Small business

From Wikipedia, the free encyclopedia
 
Small businesses on Dalrymple Street in Girvan, Scotland

Small businesses are privately owned corporations, partnerships, or sole proprietorships which have fewer employees and/or less annual revenue than a regular-sized business or corporation. Businesses are defined as "small" in terms of being able to apply for government support and qualify for preferential tax policy varies depending on the country and industry. Small businesses range from fifteen employees under the Australian Fair Work Act 2009, fifty employees according to the definition used by the European Union, and fewer than five hundred employees to qualify for many U.S. Small Business Administration programs. While small businesses can also be classified according to other methods, such as annual revenues, shipments, sales, assets, or by annual gross or net revenue or net profits, the number of employees is one of the most widely used measures.

Small businesses in many countries include service or retail operations such as convenience stores, small grocery stores, bakeries or delicatessens, hairdressers or tradespeople (e.g., carpenters, electricians), restaurants, guest houses, photographers, very small-scale manufacturing, and Internet-related businesses such as web design and computer programming. Some professionals operate as small businesses, such as lawyers, accountants, dentists, and medical doctors (although these professionals can also work for large organizations or companies). Small businesses vary a great deal in terms of size, revenues, and regulatory authorization, both within a country and from country to country. Some small businesses, such as a home accounting business, may only require a business license. On the other hand, other small businesses, such as day cares, retirement homes, and restaurants serving liquor are more heavily regulated and may require inspection and certification from various government authorities.

Characteristics

Small businesses in the Central Zone of São Paulo

Researchers and analysts of small or owner-managed businesses generally behave as if nominal organizational forms (e.g., partnership, sole-trader, or corporation), and the consequent legal and accounting boundaries of owner-managed firms are consistently meaningful. However, owner-managers often do not distinguish between their personal and business interests. Lenders also often skirt organizational (corporate) boundaries by seeking personal guarantees or accepting privately held assets as collateral. Because of this behavior, researchers and analysts may wish to be cautious in assessing the organizational types and implied boundaries relating to owner-managed firms. This includes the analysis of traditional accounting disclosures and studies that treat the firm as defined by a formal organizational structure.

Concepts of small business, self-employment, entrepreneurship, and startup

Portici di Sottoripa, Genova, Italy. Galleries tend to form clusters of small business owners over time.

The concepts of small business, self-employment, entrepreneurship, and startup overlap but also carry important distinctions. These four concepts are often conflated.Their key differences can be summarized as:

  • self-employment: an organization created primarily to provide income to the founders, i.e. sole proprietor operations.
  • entrepreneurship: all new organizations.
  • startup: a new organization created to grow (and have employees).
  • small business: an organization that is small (in employees or revenue) and may or may not have the intention to grow.

Many small businesses are sole proprietor operations consisting only of the owner, but many also have additional employees. Some small businesses that offer a product, process or service, do not have growth as their primary objective. In contrast, a business that is created to become a big firm is known as a startup. Startups aim for growth and often offer an innovative product, process, or service. The entrepreneurs of startups typically aim to scale up the company by adding employees, seeking international sales, and so on, a process which is often but not always financed by venture capital and angel investments. Successful entrepreneurs have the ability to lead a business in a positive direction by proper planning, adapting to changing environments, and understand their own strengths and weakness. Spectacular success stories stem from startups that expanded in growth. Examples would be Microsoft, Genentech, and Federal Express which all embody the sense of new venture creation on small businesses.

Self-employment provides work primarily for the founders. Entrepreneurship refers to all new businesses, including self-employment and businesses that never intend to grow big or become registered, but startups refer to new businesses that intend to grow beyond the founders, to have employees, and grow large.

Size definitions

The legal definition of "small business" varies by country and by industry. In addition to the number of employees, methods used to classify small companies include annual sales (turnover), the value of assets and net profit (balance sheet), alone or as a combination of factors.

  • In India, all the manufacturing and service enterprises having investment "Not more than Rs 10 crore" and Annual Turnover "not more than Rs 50 crore" come under this category.
  • In the United States, the Small Business Administration establishes small business size standards on an industry-by-industry basis but generally specifies a small business as having fewer than 500 employees for manufacturing businesses and less than $7.5 million in annual receipts for most non-manufacturing businesses. The definition can vary by circumstance—for example, a small business having fewer than 25 full-time equivalent employees with average annual wages below $50,000 qualifies for a tax credit under the health care reform bill Patient Protection and Affordable Care Act. By comparison, a medium-sized business or mid-sized business has fewer than 500 employees.
  • The European Union generally defines a small business as one that has fewer than fifty employees and either turnover or balance sheet less than €10 m. but the European Commission is undertaking a review of this definition. By comparison, a medium-sized business has fewer than 250 employees and either turnover less than €50 m. or balance sheet less than €43 m.
  • In Australia, a small business is defined by the Fair Work Act 2009 as one with fewer than fifteen employees. By comparison, a medium-sized business or mid-sized business has fewer than two hundred employees.
  • In South Africa, the National Small Business Amendment Act (Act 26 of 2003) defines businesses in a variety of ways using five categories previously established by the National Small Business Act (Act 102 of 1996), namely, standard industrial sector and subsector classification, size of class, equivalent of paid employees, turnover and asset value excluding fixed property.

Small businesses usually do not dominate their field.

The following table serves as a guide to business size nomenclature.

Demographics

In 2016 a study that examined the demographic of small business owners was published. The study showed that the median American small business owners were above the age of 50. The ages were distributed as 51% over 50 years old, 33% between the ages 35–49, and 16% being under the age of 35. As for sex: 55% were owned by males, 36% by females, and 9% being equal ownership of both males and females. As for race: 72% were white/Caucasian, 13.5% were Latinos, 6.3% were African American, 6.2% were Asian, and 2% as other. As for educational background: 39% had obtained a bachelor's degree or higher, 33% had some college background, and 28% received at least a high school diploma.

The United States census data for the years 2014 and 2015 shows the women's ownership share of small businesses by firm size. The data explains percentages owned by women along with the number of employees including the owner. Generally, the smaller the business, the more likely it to be owned by a woman. The data shows that about 22% of small businesses with 100-500 employees were owned by women, a percentage that rises the smaller the business. 41% of businesses with just 2-4 employees were run by women, and in businesses with just one person, that person was a woman in 51% of cases.

Franchise businesses

Franchising is a way for small business owners to benefit from the economies of scale of the big corporation (franchiser). McDonald's and Subway are examples of a franchise. The small business owner can leverage a strong brand name and purchasing power of the larger company while keeping their own investment affordable. However, some franchisees conclude that they suffer the "worst of both worlds" feeling they are too restricted by corporate mandates and lack true independence. It is an assumption that small business is just franchisees, but the truth is many franchisers are also small businesses, Although considered to be a successful way of doing business, literature has proved that there is a high failure rate in franchising as well, especially in the UK, where research indicates that out of 1658 franchising companies operating in 1984, only 601 remained in 1998, a mere 36%.

Retailers' cooperative

A retailers' cooperative is a type of cooperative that employs economies of scale on behalf of its retailer members. Retailers' cooperatives use their purchasing power to acquire discounts from manufacturers and often share marketing expenses. They are often recognized as "local groups" because they own their own stores within the community. It is common for locally-owned grocery stores, hardware stores, and pharmacies to participate in retailers' cooperatives. Ace Hardware, True Value, and NAPA are examples of a retailers' cooperative. Retail cooperatives also allow consumers to supply their own earnings and gain bargaining power outside of the business sector. Retail cooperatives mainly reside within small communities where local businesses are often shut down.

Advantages

Small business in Bursa, Turkey. One of the claimed advantages of small business owners is the ability to serve market niches not served by mass production industries. Consider how few major corporations would be willing to deal with the risks and uncertainty that small antique store deals with buying and selling non-standardized items and making quick assessments of the value of rare items.

Many small businesses can be started at a low cost and on a part-time basis, while a person continues a regular job with an employer or provides care for family members in the home. In developing countries, many small businesses are sole-proprietor operations such as selling products at a market stall or preparing hot food to sell on the street, which provide a small income. In the 2000s, a small business is also well suited to Internet marketing; because, it can easily serve specialized niches, something that would have been more difficult before the Internet revolution which began in the late 1990s. Internet marketing gives small businesses the ability to market with smaller budgets. Adapting to change is crucial in business and particularly small business; not being tied to the bureaucratic inertia associated with large corporations, small businesses can respond to changing marketplace demand more quickly. Small business proprietors tend to be in closer personal contact with their customers and clients than large corporations, as small business owners see their customers in person each week.

One study showed that small, local businesses are better for a local economy than the introduction of new chain stores. By opening up new national level chain stores, the profits of locally owned businesses greatly decrease and many businesses end up failing and having to close. This creates an exponential effect. When one store closes, people lose their jobs, other businesses lose business from the failed business, and so on. In many cases, large firms displace just as many jobs as they create.

Independence

Independence is another advantage of owning a small business. A small business owner does not have to report to a supervisor or manager. Also, many people desire to make their own decisions, take their own risks, and reap the rewards of their efforts. Small business owners possess the flexibility and freedom to make their own decisions within the constraints imposed by economic and other environmental factors. However, entrepreneurs have to work for very long hours and understand that ultimately their customers are their bosses.

Small businesses (often carried out by family members) may adjust quicker to the changing conditions; however, they may also be closed to the absorption of new knowledge and employing new labor from outside.

Financial reporting

Small businesses benefit from less extensive accounting and financial reporting requirements than those faced by larger businesses.

The European Union's Directive on annual financial statements of 2013 aims to "limit administrative burdens and provide for simple and robust accounting rules, especially for small and medium-sized enterprises (SMEs)". In the UK, the Companies, Partnerships and Groups (Accounts and Reports) Regulations 2015 transposed the EU Directive into UK law and amended the reporting regime for reduced disclosure accounts for any accounting period commencing on or after 1 January 2016. "Abbreviated accounts" were permitted for smaller entities under "FRSSE", the Financial Reporting Standard for Smaller Entities). Until 2015, companies deemed small under the UK Companies Act 2006 were allowed to use this standard. For accounting years ending on or after 1 January 2016, FRSSE is no longer available, but there are options known as "abridged accounts" and "filleted accounts":

  • Abridged accounts: accounting for profit / loss begins with the declaration of gross profit or loss, not turnover
  • Filleted financial statements or filleted accounts: profit and loss accounts are excluded, but balance sheet and balance sheet notes are to be disclosed.

Alternatively, the smallest companies are able to file "micro-entity accounts". FRS 105 is a Financial Reporting Standard applicable to the Micro-entities Regime.

Challenges

Small businesses often face a variety of problems, some of which are related to their size. A frequent cause of bankruptcy is under capitalization. This is often a result of poor planning rather than economic conditions. It is a common rule of thumb that the entrepreneur should have access to a sum of money at least equal to the projected revenue for the first year of business in addition to his or her anticipated expenses. For example, if the prospective owner thinks that he or she will generate 100,000 in revenues in the first year with 150,000 in start-up expenses, then he or she should have not less than 250,000 available. Start-up expenses are often grossly underestimated adding to the burden of the business. Failure to provide this level of funding for the company could leave the owner liable for all of the company's debt should he or she end up in bankruptcy court, under the theory of undercapitalization.

In addition to ensuring that the business has enough capital, the small business owner must also be mindful of contribution margin (sales minus variable costs). To break even, the business must be able to reach a level of sales where the contribution margin equals fixed costs. When they first start, many small business owners underprice their products to a point where even at their maximum capacity, it would be impossible to break even. Cost controls or price increases often resolve this problem.

In the United States, some of the largest concerns of small business owners are insurance costs (such as liability and health), rising energy costs, taxes, and tax compliance. In the United Kingdom and Australia, small business owners tend to be more concerned with perceived excessive governmental red tape.

Contracting fraud has been an ongoing problem for small businesses in the United States. Small businesses are legally obligated to receive a fair portion (23 percent) of the total value of all the government's prime contracts as mandated by the Small Business Act of 1953. Since 2002, a series of federal investigations have found fraud, abuse, loopholes, and a lack of oversight in federal small business contracting, which has led to the diversion of billions of dollars in small business contracts to large corporations.

Another problem for many small businesses is termed the 'Entrepreneurial Myth' or E-Myth. The mythic assumption is that an expert in a given technical field will also be an expert at running that kind of business. Additional business management skills are needed to keep a business running smoothly. Some of this misunderstanding arises from the failure to distinguish between small business managers as entrepreneurs or capitalists. While nearly all owner-managers of small firms are obliged to assume the role of capitalist, only a minority will act as entrepreneurs. The line between an owner-manager and an entrepreneur can be defined by whether or not their business is growth-oriented. In general, small business owners are primarily focused on surviving rather than growing; therefore, not experiencing the five stages of the corporate life cycle (birth, growth, maturity, revival, and decline) as an entrepreneur would.

Another problem for many small businesses is the capacity of much larger businesses to influence or sometimes determine their chances for success. Business networking and social media has been used as a major tool by small businesses in the UK, but most of them just use a "scattergun" approach in a desperate attempt to exploit the market which is not that successful. Over half of small firms lack a business plan, a tool that is considered one of the most important factors for a venture's success. Business planning is associated with improved growth prospects. Funders and investors usually require a business plan. A plan also serves as a strategic planning document for owners and CEOs, which can be used as a "bible" for decision-making. 

An international trade survey indicated that the British share of businesses that are exporting rose from 32% in 2012 to 39% in 2013. Although this may seem positive, in reality, the growth is slow, as small business owners shy away from exporting due to actual and perceived barriers. Learning the basics of a foreign language could be the solution to open doors to new trade markets, it is a reality that not all foreign business partners speak English. China is stated to grow by 7.6% in 2013 and still, 95% of business owners who want to export to China have no desire and no knowledge to learn their local language.

Bankruptcy

When small business fails, the owner may file for bankruptcy. In most cases, this can be handled through a personal bankruptcy filing. Corporations can file bankruptcy, but if it is out of business and valuable corporate assets are likely to be repossessed by secured creditors, there is little advantage to going to the expense of a corporate bankruptcy. Many states offer exemptions for small business assets so they can continue to operate during and after personal bankruptcy. However, corporate assets are normally not exempt; hence, it may be more difficult to continue operating an incorporated business if the owner files bankruptcy. Researchers have examined small business failures in some depth, with attempts to model the predictability of failure.

Social responsibility

Small businesses can encounter several problems related to engaging in corporate social responsibility, due to characteristics inherent in their size. Owners of small businesses often participate heavily in the day-to-day operations of their companies. This results in a lack of time for the owner to coordinate socially responsible efforts, such as supporting local charities or not-for-profit activities. Additionally, a small business owner's expertise often falls outside the realm of socially responsible practices, which can contribute to a lack of participation. Small businesses also face a form of peer pressure from larger forces in their respective industries, making it difficult to oppose and work against industry expectations. Furthermore, small businesses undergo stress from shareholder expectations. Because small businesses have more personal relationships with their patrons and local shareholders, they must also be prepared to withstand closer scrutiny if they want to share in the benefits of committing to socially responsible practices or not.

Job quality

While small businesses employ over half the workforce in the US and have been established as a main driving force behind job creation, the quality of the jobs these businesses create has been called into question. Small businesses generally employ individuals from the Secondary labor market. As a result, in the U.S., wages are 49% higher for employees of large firms. Additionally, many small businesses struggle or are unable to provide employees with benefits they would be given at larger firms. Research from the U.S. Small Business Administration indicates that employees of large firms are 17% more likely to receive benefits including salary, paid leave, paid vacation, bonuses, insurance, and retirement plans. Both lower wages and fewer benefits combine to create a job turnover rate among U.S. small businesses that is three times higher than large firms. Employees of small businesses also must adapt to the higher failure rate of small firms, which means that they are more likely to lose their job due to the firm going under. In the U.S. 69% of small businesses last at least two years, but this percentage drops to 51% for firms reaching five years in operation. The U.S. Small Business Administration counts companies with as much as $35.5 million in sales and 1,500 employees as "small businesses", depending on the industry. Outside government, companies with less than $7 million in sales and fewer than five hundred employees are widely considered small businesses.

Cyber crime

Cybercrime in the business world can be broken down into 4 main categories. They include loss of reputation and consumer confidence, cost of fixing the issue, loss of capital and assets, and legal difficulties that can come from these problems. Loss of reputation and consumer confidence can be impacted greatly after one attack. Many small businesses will struggle to gain confidence and trust in their customers after being known for having problems prior. The cost of fixing the cyber attack would require experts outside of their field to further the investigation and find the problem. Being down for a business means losing money at the same time. This could halt the online operations and mean the business could potentially be down for a long period of time. Loss of capital and assets ties well in with the cost of fixing the issue. During a cyberattack, a business may lose its funds for that business. Worst-case scenario, a business may actually lose all its working capital and funds. The legal difficulties involved with cybercrime can become pricy and hurt the business itself for not having standard security measures and standards. Security not only for the business but more importantly the customer should be the number one priority when dealing with security protocol.

The monetary dollar damage caused by cybercrime in 2016 equaled out to be over 1.33 billion dollars in the United States alone. In 2016, California alone had over 255 million dollars reported to the IC3. The average company this year in the United States amounted to 17.36 million dollars in cybercrime attacks. Certain cyber attacks can vary on how long it takes to solve a problem. It can take upwards to 69 days for an average everyday attack on a business. The types of attacks include viruses and malware issues. Employee activities within the workspace can also render a cyber attack. Employees using mobile devices or remote work access off the job makes it easier for a cyber attack to occur.

Marketing

Although small businesses have close relationships with their existing customers, finding new customers and reaching new markets is a major challenge for small business owners. Small businesses typically find themselves strapped for time to do marketing, as they have to run the day-to-day aspects of the business. To create a continual stream of new business and find new clients and customers, they must work on marketing their business continuously. Low sales (the result of poor marketing) is one of the major reasons for small business failure. Common marketing techniques for small business include business networking (e.g., attending Chamber of Commerce events or trade fairs), "word of mouth" promotion by existing customers, customer referrals, Yellow pages directories, television, radio, and outdoor ads (e.g., roadside billboards), print ads, and Internet marketing. TV ads can be quite expensive, so they are normally intended to create awareness of a product or service. Another means by which small businesses can advertise is through the use of "deal of the day" websites such as Groupon and Living Social. These Internet deals encourage customers to patronize small businesses.

Example of keyword analysis based on market competition

Many small business owners find internet marketing more affordable. Google AdWords and Yahoo! Search Marketing are two popular options of getting small business products or services in front of motivated web searchers. Social media has also become an affordable route of marketing for small businesses. It is a fraction of the cost of traditional marketing and small businesses can do it themselves or find small social marketing agencies that they can hire out for a small fee. Statistically, social media marketing has a higher lead-to-close rate than traditional media. Successful online small business marketers are also adept at utilizing the most relevant keywords in their website content. Advertising on niche websites that are frequented by potential customers can also be effective, but with the long tail of the Internet, it can be time-intensive to advertise on enough websites to garner an effective reach.

Creating a business website has become increasingly affordable with many do-it-yourself programs now available for beginners. A website can provide significant marketing exposure for small businesses when marketed through the Internet and other channels. Some popular services are WordPress, Joomla, Squarespace, and Wix. Social media has proven to be very useful in gaining additional exposure for many small businesses. Many small business owners use Facebook and Twitter as a way to reach out to their loyal customers to give them news about specials of the day or special coupons, generate repeat business and reach out to new potential clients. The relational nature of social media, along with its immediacy and twenty-four-hour presence lend an intimacy to the relationships small businesses can have with their customers while making it more efficient for them to communicate with greater numbers. Facebook ads are also a very cost-effective way for small business owners to reach a targeted audience with a very specific message. In addition to the social networking sites, blogs have become a highly effective way for small businesses to position themselves as experts on issues that are important to their customers. This can be done with a proprietary blog and/or by using a back-link strategy wherein the marketer comments on other blogs and leaves a link to the small business' own website. Posting to a blog about the company's business or service area regularly can increase web traffic to a company website.

Marketing plan

  • Market research – To produce a marketing plan for small businesses, research needs to be done on similar businesses, which should include desk research (done online or with directories) and field research. This gives an insight into the target group’s behavior and shopping patterns. Analyzing the competitor’s marketing strategies makes it easier for small businesses to gain market share.
  • Marketing mix – Marketing mix is a crucial factor for any business to be successful. Especially for a small business, examining a competitor’s marketing mix can be very helpful. An appropriate market mix, which uses different types of marketing, can help to boost sales.
  • Product life cycle – After the launch of the business, crucial points of focus should be the growth phase (adding customers, adding products or services, and/or expanding to new markets) and working towards the maturity phase. Once the business reaches the maturity stage, an extension strategy should be in place. Re-launching is also an option at this stage. Pricing strategy should be flexible and based on the different stages of the product life cycle.
  • Promotion techniques – It is preferable to keep promotion expenses as low as possible. ‘Word of mouth’, ‘email marketing’, ‘print-ads’ in local newspapers, etc. can be effective.
  • Channels of distribution – Selecting an effective channel of distribution may reduce the promotional expenses as well as overall expenses for a small business.

Contribution to the economy

In the US, small businesses (fewer than five hundred employees) account for more than half the non-farm, private GDP and around half the private sector employment. Regarding small business, the top job provider is those with fewer than ten employees, and those with ten or more but fewer than twenty employees comes in as the second, and those with twenty or more but fewer than one hundred employees comes in as the third (interpolation of data from the following references). The most recent data shows firms with fewer than twenty employees account for slightly more than 18% of the employment.

According to "The Family Business Review", "there are approximately seventeen million sole-proprietorship in the US. It can be argued that a sole-proprietorship (an unincorporated business owned by a single person) is a type of family business" and "there are twenty-two million small businesses (fewer than five hundred employees) in the US and approximately 14,000 big businesses". Also, it has been found that small businesses created the newest jobs in communities, "In 1979, David Birch published the first empirical evidence that small firms (fewer than 100 employees) created the newest jobs", and Edmiston claimed that "perhaps the greatest generator of interest in entrepreneurship and small business is the widely held belief that small businesses in the United States create most new jobs. The evidence suggests that small businesses indeed create a substantial majority of net new jobs in an average year." The U.S. Small Business Administration has found small businesses have created two-thirds of net new private-sector jobs in the US since 2007. Local businesses provide competition to each other and also challenge corporate giants. Of the 5,369,068 employer firms in 1995, 78.8 percent had fewer than ten employees, and 99.7 percent had fewer than five hundred employees.

Sources of funding

Small businesses in Biloela, Central Queensland, Australia, 1949
 

Small businesses use various sources available for start-up capital:

  • Self-financing by the owner through cash savings, equity loan on his or her home, and or other assets
  • Loans or financial gifts from friends or relatives
  • Grants from private foundations, government, or other sources
  • Private stock issue
  • Forming partnerships
  • Angel investors
  • Loans from banks, credit unions, or other financial institutions
  • SME finance, including collateral-based lending and venture capital, given sufficiently sound business venture plans

Some small businesses are further financed through credit card debt—usually a risky choice, given that the interest rate on credit cards is often several times the rate that would be paid on a line of credit at a bank or a bank loan and terms can change unpredictably. Recent research suggests that the use of credit scores in small business lending by community banks is surprisingly widespread. Moreover, the scores employed tend to be the consumer credit scores of the small business owners rather than the more encompassing small business credit scores that include data on the firms as well as on the owners. Many owners seek a bank loan in the name of their business; however, banks will usually insist on a personal guarantee by the business owner.

On October 2010, Alejandro Cremades and Tanya Prive founded the first equity crowdfunding platform for small businesses in history as an alternative source of financing. The platform operates under the name of Rock The Post.

Government support

Several organizations in the United States also provide help for the small business sector, such as the Internal Revenue Service's Small Business and Self-Employed One-Stop Resource. The Small Business Administration (SBA) runs several loan programs that may help a small business secure loans. In these programs, the SBA guarantees a portion of the loan to the issuing bank, and thus, relieves the bank of some of the risk of extending the loan to a small business. The SBA also requires business owners to pledge personal assets and sign as a personal guarantee for the loan. The 8(a) Business Development Program assists in the development of small businesses owned and operated by African Americans, Hispanics, and Asians.

Canadian small businesses can take advantage of federally funded programs and services. See Federal financing for small businesses in Canada (grants and loans).

In the United Kingdom, the Small Business Commissioner (SBC) provides information and advice for small businesses and deals with complaints resolution with specific reference to late payment problems and other unfavourable payment practices. The SBC's role is to make non-binding recommendations advising on how the parties can resolve a dispute.

Small businesses are also encouraged per public policy on taxation. For example, from January 1, 2020, Armenia introduced a special micro-entrepreneurship tax system with a non-taxable base of 24 million AMD. Accordingly, a micro-business will be exempted from taxes other than income tax which will not exceed 5,000 AMD per employee. 

Business networks and advocacy groups

Small businesses often join or come together to form organizations to advocate for their causes or to achieve economies of scale that larger businesses benefit from, such as the opportunity to buy cheaper health insurance in bulk. These organizations include local or regional groups such as Chambers of Commerce and independent business alliances, as well as national or international industry-specific organizations. Such groups often serve a dual purpose, as business networks to provide marketing and connect members to potential sales leads and suppliers, and also as advocacy groups, bringing together many small businesses to provide a stronger voice in regional or national politics. In the case of independent business alliances, promoting the value of locally owned, independent business (not necessarily small) through public education campaigns is integral to their work.

The largest regional small business group in the United States is the Council of Smaller Enterprises, located in Greater Cleveland.

United Kingdom Trade and Investment gives out research in different markets around the world, and research in program planning and promotional activities to exporters. The BEXA's (British Exporters Association) role is to connect new exporters to expert services. It can provide details about regional export contacts, who could be made informally to discuss issues. Trade associations and all major banks often provide links to international groups in foreign markets, and some help set up joint ventures and trade fairs.

Several youth organizations, including 4-H, Junior Achievement, and Scouting, have interactive programs and training to help young people run their own small business under adult supervision.

Philosophy of science

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Philosophy_of_science

Philosophy of science is a branch of philosophy concerned with the foundations, methods, and implications of science. The central questions of this study concern what qualifies as science, the reliability of scientific theories, and the ultimate purpose of science. This discipline overlaps with metaphysics, ontology, and epistemology, for example, when it explores the relationship between science and truth. Philosophy of science focuses on metaphysical, epistemic and semantic aspects of science. Ethical issues such as bioethics and scientific misconduct are often considered ethics or science studies rather than philosophy of science.

There is no consensus among philosophers about many of the central problems concerned with the philosophy of science, including whether science can reveal the truth about unobservable things and whether scientific reasoning can be justified at all. In addition to these general questions about science as a whole, philosophers of science consider problems that apply to particular sciences (such as biology or physics). Some philosophers of science also use contemporary results in science to reach conclusions about philosophy itself.

While philosophical thought pertaining to science dates back at least to the time of Aristotle, general philosophy of science emerged as a distinct discipline only in the 20th century in the wake of the logical positivist movement, which aimed to formulate criteria for ensuring all philosophical statements' meaningfulness and objectively assessing them. Charles Sanders Peirce and Karl Popper moved on from positivism to establish a modern set of standards for scientific methodology. Thomas Kuhn's 1962 book The Structure of Scientific Revolutions was also formative, challenging the view of scientific progress as steady, cumulative acquisition of knowledge based on a fixed method of systematic experimentation and instead arguing that any progress is relative to a "paradigm", the set of questions, concepts, and practices that define a scientific discipline in a particular historical period.

Subsequently, the coherentist approach to science, in which a theory is validated if it makes sense of observations as part of a coherent whole, became prominent due to W.V. Quine and others. Some thinkers such as Stephen Jay Gould seek to ground science in axiomatic assumptions, such as the uniformity of nature. A vocal minority of philosophers, and Paul Feyerabend in particular, argue that there is no such thing as the "scientific method", so all approaches to science should be allowed, including explicitly supernatural ones. Another approach to thinking about science involves studying how knowledge is created from a sociological perspective, an approach represented by scholars like David Bloor and Barry Barnes. Finally, a tradition in continental philosophy approaches science from the perspective of a rigorous analysis of human experience.

Philosophies of the particular sciences range from questions about the nature of time raised by Einstein's general relativity, to the implications of economics for public policy. A central theme is whether the terms of one scientific theory can be intra- or intertheoretically reduced to the terms of another. That is, can chemistry be reduced to physics, or can sociology be reduced to individual psychology? The general questions of philosophy of science also arise with greater specificity in some particular sciences. For instance, the question of the validity of scientific reasoning is seen in a different guise in the foundations of statistics. The question of what counts as science and what should be excluded arises as a life-or-death matter in the philosophy of medicine. Additionally, the philosophies of biology, of psychology, and of the social sciences explore whether the scientific studies of human nature can achieve objectivity or are inevitably shaped by values and by social relations.

Introduction

Defining science

Karl Popper in the 1980s

Distinguishing between science and non-science is referred to as the demarcation problem. For example, should psychoanalysis, creation science, and historical materialism be considered pseudosciences? Karl Popper called this the central question in the philosophy of science. However, no unified account of the problem has won acceptance among philosophers, and some regard the problem as unsolvable or uninteresting. Martin Gardner has argued for the use of a Potter Stewart standard ("I know it when I see it") for recognizing pseudoscience.

Early attempts by the logical positivists grounded science in observation while non-science was non-observational and hence meaningless. Popper argued that the central property of science is falsifiability. That is, every genuinely scientific claim is capable of being proven false, at least in principle.

An area of study or speculation that masquerades as science in an attempt to claim a legitimacy that it would not otherwise be able to achieve is referred to as pseudoscience, fringe science (though often times a fringe science becomes mainstream, even developing into a Paradigm Shift), or junk science. Physicist Richard Feynman coined the term "cargo cult science" for cases in which researchers believe they are doing science because their activities have the outward appearance of it but actually lack the "kind of utter honesty" that allows their results to be rigorously evaluated.

Scientific explanation

A closely related question is what counts as a good scientific explanation. In addition to providing predictions about future events, society often takes scientific theories to provide explanations for events that occur regularly or have already occurred. Philosophers have investigated the criteria by which a scientific theory can be said to have successfully explained a phenomenon, as well as what it means to say a scientific theory has explanatory power.

One early and influential account of scientific explanation is deductive-nomological model. It says that a successful scientific explanation must deduce the occurrence of the phenomena in question from a scientific law. This view has been subjected to substantial criticism, resulting in several widely acknowledged counterexamples to the theory. It is especially challenging to characterize what is meant by an explanation when the thing to be explained cannot be deduced from any law because it is a matter of chance, or otherwise cannot be perfectly predicted from what is known. Wesley Salmon developed a model in which a good scientific explanation must be statistically relevant to the outcome to be explained. Others have argued that the key to a good explanation is unifying disparate phenomena or providing a causal mechanism.

Justifying science

The expectations chickens might form about farmer behavior illustrate the "problem of induction."

Although it is often taken for granted, it is not at all clear how one can infer the validity of a general statement from a number of specific instances or infer the truth of a theory from a series of successful tests. For example, a chicken observes that each morning the farmer comes and gives it food, for hundreds of days in a row. The chicken may therefore use inductive reasoning to infer that the farmer will bring food every morning. However, one morning, the farmer comes and kills the chicken. How is scientific reasoning more trustworthy than the chicken's reasoning?

One approach is to acknowledge that induction cannot achieve certainty, but observing more instances of a general statement can at least make the general statement more probable. So the chicken would be right to conclude from all those mornings that it is likely the farmer will come with food again the next morning, even if it cannot be certain. However, there remain difficult questions about the process of interpreting any given evidence into a probability that the general statement is true. One way out of these particular difficulties is to declare that all beliefs about scientific theories are subjective, or personal, and correct reasoning is merely about how evidence should change one's subjective beliefs over time.

Some argue that what scientists do is not inductive reasoning at all but rather abductive reasoning, or inference to the best explanation. In this account, science is not about generalizing specific instances but rather about hypothesizing explanations for what is observed. As discussed in the previous section, it is not always clear what is meant by the "best explanation". Ockham's razor, which counsels choosing the simplest available explanation, thus plays an important role in some versions of this approach. To return to the example of the chicken, would it be simpler to suppose that the farmer cares about it and will continue taking care of it indefinitely or that the farmer is fattening it up for slaughter? Philosophers have tried to make this heuristic principle more precise in terms of theoretical parsimony or other measures. Yet, although various measures of simplicity have been brought forward as potential candidates, it is generally accepted that there is no such thing as a theory-independent measure of simplicity. In other words, there appear to be as many different measures of simplicity as there are theories themselves, and the task of choosing between measures of simplicity appears to be every bit as problematic as the job of choosing between theories. Nicholas Maxwell has argued for some decades that unity rather than simplicity is the key non-empirical factor in influencing choice of theory in science, persistent preference for unified theories in effect committing science to the acceptance of a metaphysical thesis concerning unity in nature. In order to improve this problematic thesis, it needs to be represented in the form of a hierarchy of theses, each thesis becoming more insubstantial as one goes up the hierarchy.

Observation inseparable from theory

Five balls of light are arranged in a cross shape.
Seen through a telescope, the Einstein cross seems to provide evidence for five different objects, but this observation is theory-laden. If we assume the theory of general relativity, the image only provides evidence for two objects.

When making observations, scientists look through telescopes, study images on electronic screens, record meter readings, and so on. Generally, on a basic level, they can agree on what they see, e.g., the thermometer shows 37.9 degrees C. But, if these scientists have different ideas about the theories that have been developed to explain these basic observations, they may disagree about what they are observing. For example, before Albert Einstein's general theory of relativity, observers would have likely interpreted an image of the Einstein cross as five different objects in space. In light of that theory, however, astronomers will tell you that there are actually only two objects, one in the center and four different images of a second object around the sides. Alternatively, if other scientists suspect that something is wrong with the telescope and only one object is actually being observed, they are operating under yet another theory. Observations that cannot be separated from theoretical interpretation are said to be theory-laden.

All observation involves both perception and cognition. That is, one does not make an observation passively, but rather is actively engaged in distinguishing the phenomenon being observed from surrounding sensory data. Therefore, observations are affected by one's underlying understanding of the way in which the world functions, and that understanding may influence what is perceived, noticed, or deemed worthy of consideration. In this sense, it can be argued that all observation is theory-laden.

The purpose of science

Should science aim to determine ultimate truth, or are there questions that science cannot answer? Scientific realists claim that science aims at truth and that one ought to regard scientific theories as true, approximately true, or likely true. Conversely, scientific anti-realists argue that science does not aim (or at least does not succeed) at truth, especially truth about unobservables like electrons or other universes. Instrumentalists argue that scientific theories should only be evaluated on whether they are useful. In their view, whether theories are true or not is beside the point, because the purpose of science is to make predictions and enable effective technology.

Realists often point to the success of recent scientific theories as evidence for the truth (or near truth) of current theories. Antirealists point to either the many false theories in the history of science,epistemic morals, the success of false modeling assumptions, or widely termed postmodern criticisms of objectivity as evidence against scientific realism. Antirealists attempt to explain the success of scientific theories without reference to truth. Some antirealists claim that scientific theories aim at being accurate only about observable objects and argue that their success is primarily judged by that criterion.

Values and science

Values intersect with science in different ways. There are epistemic values that mainly guide the scientific research. The scientific enterprise is embedded in particular culture and values through individual practitioners. Values emerge from science, both as product and process and can be distributed among several cultures in the society.

If it is unclear what counts as science, how the process of confirming theories works, and what the purpose of science is, there is considerable scope for values and other social influences to shape science. Indeed, values can play a role ranging from determining which research gets funded to influencing which theories achieve scientific consensus. For example, in the 19th century, cultural values held by scientists about race shaped research on evolution, and values concerning social class influenced debates on phrenology (considered scientific at the time). Feminist philosophers of science, sociologists of science, and others explore how social values affect science.

History

Pre-modern

The origins of philosophy of science trace back to Plato and Aristotle who distinguished the forms of approximate and exact reasoning, set out the threefold scheme of abductive, deductive, and inductive inference, and also analyzed reasoning by analogy. The eleventh century Arab polymath Ibn al-Haytham (known in Latin as Alhazen) conducted his research in optics by way of controlled experimental testing and applied geometry, especially in his investigations into the images resulting from the reflection and refraction of light. Roger Bacon (1214–1294), an English thinker and experimenter heavily influenced by al-Haytham, is recognized by many to be the father of modern scientific method. His view that mathematics was essential to a correct understanding of natural philosophy was considered to be 400 years ahead of its time.

Modern

Francis Bacon's statue at Gray's Inn, South Square, London

Francis Bacon (no direct relation to Roger, who lived 300 years earlier) was a seminal figure in philosophy of science at the time of the Scientific Revolution. In his work Novum Organum (1620)—an allusion to Aristotle's Organon—Bacon outlined a new system of logic to improve upon the old philosophical process of syllogism. Bacon's method relied on experimental histories to eliminate alternative theories. In 1637, René Descartes established a new framework for grounding scientific knowledge in his treatise, Discourse on Method, advocating the central role of reason as opposed to sensory experience. By contrast, in 1713, the 2nd edition of Isaac Newton's Philosophiae Naturalis Principia Mathematica argued that "... hypotheses ... have no place in experimental philosophy. In this philosophy[,] propositions are deduced from the phenomena and rendered general by induction." This passage influenced a "later generation of philosophically-inclined readers to pronounce a ban on causal hypotheses in natural philosophy". In particular, later in the 18th century, David Hume would famously articulate skepticism about the ability of science to determine causality and gave a definitive formulation of the problem of induction. The 19th century writings of John Stuart Mill are also considered important in the formation of current conceptions of the scientific method, as well as anticipating later accounts of scientific explanation.

Logical positivism

Instrumentalism became popular among physicists around the turn of the 20th century, after which logical positivism defined the field for several decades. Logical positivism accepts only testable statements as meaningful, rejects metaphysical interpretations, and embraces verificationism (a set of theories of knowledge that combines logicism, empiricism, and linguistics to ground philosophy on a basis consistent with examples from the empirical sciences). Seeking to overhaul all of philosophy and convert it to a new scientific philosophy, the Berlin Circle and the Vienna Circle propounded logical positivism in the late 1920s.

Interpreting Ludwig Wittgenstein's early philosophy of language, logical positivists identified a verifiability principle or criterion of cognitive meaningfulness. From Bertrand Russell's logicism they sought reduction of mathematics to logic. They also embraced Russell's logical atomism, Ernst Mach's phenomenalism—whereby the mind knows only actual or potential sensory experience, which is the content of all sciences, whether physics or psychology—and Percy Bridgman's operationalism. Thereby, only the verifiable was scientific and cognitively meaningful, whereas the unverifiable was unscientific, cognitively meaningless "pseudostatements"—metaphysical, emotive, or such—not worthy of further review by philosophers, who were newly tasked to organize knowledge rather than develop new knowledge.

Logical positivism is commonly portrayed as taking the extreme position that scientific language should never refer to anything unobservable—even the seemingly core notions of causality, mechanism, and principles—but that is an exaggeration. Talk of such unobservables could be allowed as metaphorical—direct observations viewed in the abstract—or at worst metaphysical or emotional. Theoretical laws would be reduced to empirical laws, while theoretical terms would garner meaning from observational terms via correspondence rules. Mathematics in physics would reduce to symbolic logic via logicism, while rational reconstruction would convert ordinary language into standardized equivalents, all networked and united by a logical syntax. A scientific theory would be stated with its method of verification, whereby a logical calculus or empirical operation could verify its falsity or truth.

In the late 1930s, logical positivists fled Germany and Austria for Britain and America. By then, many had replaced Mach's phenomenalism with Otto Neurath's physicalism, and Rudolf Carnap had sought to replace verification with simply confirmation. With World War II's close in 1945, logical positivism became milder, logical empiricism, led largely by Carl Hempel, in America, who expounded the covering law model of scientific explanation as a way of identifying the logical form of explanations without any reference to the suspect notion of "causation". The logical positivist movement became a major underpinning of analytic philosophy, and dominated Anglosphere philosophy, including philosophy of science, while influencing sciences, into the 1960s. Yet the movement failed to resolve its central problems, and its doctrines were increasingly assaulted. Nevertheless, it brought about the establishment of philosophy of science as a distinct subdiscipline of philosophy, with Carl Hempel playing a key role.

For Kuhn, the addition of epicycles in Ptolemaic astronomy was "normal science" within a paradigm, whereas the Copernican revolution was a paradigm shift.

Thomas Kuhn

In the 1962 book The Structure of Scientific Revolutions, Thomas Kuhn argued that the process of observation and evaluation takes place within a paradigm, a logically consistent "portrait" of the world that is consistent with observations made from its framing. A paradigm also encompasses the set of questions and practices that define a scientific discipline. He characterized normal science as the process of observation and "puzzle solving" which takes place within a paradigm, whereas revolutionary science occurs when one paradigm overtakes another in a paradigm shift.

Kuhn denied that it is ever possible to isolate the hypothesis being tested from the influence of the theory in which the observations are grounded, and he argued that it is not possible to evaluate competing paradigms independently. More than one logically consistent construct can paint a usable likeness of the world, but there is no common ground from which to pit two against each other, theory against theory. Each paradigm has its own distinct questions, aims, and interpretations. Neither provides a standard by which the other can be judged, so there is no clear way to measure scientific progress across paradigms.

For Kuhn, the choice of paradigm was sustained by rational processes, but not ultimately determined by them. The choice between paradigms involves setting two or more "portraits" against the world and deciding which likeness is most promising. For Kuhn, acceptance or rejection of a paradigm is a social process as much as a logical process. Kuhn's position, however, is not one of relativism. According to Kuhn, a paradigm shift occurs when a significant number of observational anomalies arise in the old paradigm and a new paradigm makes sense of them. That is, the choice of a new paradigm is based on observations, even though those observations are made against the background of the old paradigm.

Current approaches

Naturalism's axiomatic assumptions

All scientific study inescapably builds on at least some essential assumptions that are untested by scientific processes. Kuhn concurs that all science is based on an approved agenda of unprovable assumptions about the character of the universe, rather than merely on empirical facts. These assumptions—a paradigm—comprise a collection of beliefs, values and techniques that are held by a given scientific community, which legitimize their systems and set the limitations to their investigation. For naturalists, nature is the only reality, the only paradigm. There is no such thing as 'supernatural'. The scientific method is to be used to investigate all reality, and Naturalism is the implicit philosophy of working scientists.

The following basic assumptions are needed to justify the scientific method.

  1. that there is an objective reality shared by all rational observers. "The basis for rationality is acceptance of an external objective reality.". "As an individual we cannot know that the sensory information we perceive is generated artificially or originates from a real world. Any belief that it arises from a real world outside us is actually an assumption. It seems more beneficial to assume that an objective reality exists than to live with solipsism, and so people are quite happy to make this assumption. In fact we made this assumption unconsciously when we began to learn about the world as infants. The world outside ourselves appears to respond in ways which are consistent with it being real. ... The assumption of objectivism is essential if we are to attach the contemporary meanings to our sensations and feelings and make more sense of them." "Without this assumption, there would be only the thoughts and images in our own mind (which would be the only existing mind) and there would be no need of science, or anything else."
  2. that this objective reality is governed by natural laws. "Science, at least today, assumes that the universe obeys to knoweable principles that don't depend on time or place, nor on subjective parameters such as what we think, know or how we behave." Hugh Gauch argues that science presupposes that "the physical world is orderly and comprehensible."
  3. that reality can be discovered by means of systematic observation and experimentation. Stanley Sobottka said, "The assumption of external reality is necessary for science to function and to flourish. For the most part, science is the discovering and explaining of the external world." "Science attempts to produce knowledge that is as universal and objective as possible within the realm of human understanding."
  4. that Nature has uniformity of laws and most if not all things in nature must have at least a natural cause. Biologist Stephen Jay Gould referred to these two closely related propositions as the constancy of nature's laws and the operation of known processes. Simpson agrees that the axiom of uniformity of law, an unprovable postulate, is necessary in order for scientists to extrapolate inductive inference into the unobservable past in order to meaningfully study it.
  5. that experimental procedures will be done satisfactorily without any deliberate or unintentional mistakes that will influence the results.
  6. that experimenters won't be significantly biased by their presumptions.
  7. that random sampling is representative of the entire population. A simple random sample (SRS) is the most basic probabilistic option used for creating a sample from a population. The benefit of SRS is that the investigator is guaranteed to choose a sample that represents the population that ensures statistically valid conclusions.

Coherentism

Jeremiah Horrocks makes the first observation of the transit of Venus in 1639, as imagined by the artist W. R. Lavender in 1903

In contrast to the view that science rests on foundational assumptions, coherentism asserts that statements are justified by being a part of a coherent system. Or, rather, individual statements cannot be validated on their own: only coherent systems can be justified. A prediction of a transit of Venus is justified by its being coherent with broader beliefs about celestial mechanics and earlier observations. As explained above, observation is a cognitive act. That is, it relies on a pre-existing understanding, a systematic set of beliefs. An observation of a transit of Venus requires a huge range of auxiliary beliefs, such as those that describe the optics of telescopes, the mechanics of the telescope mount, and an understanding of celestial mechanics. If the prediction fails and a transit is not observed, that is likely to occasion an adjustment in the system, a change in some auxiliary assumption, rather than a rejection of the theoretical system.

In fact, according to the Duhem–Quine thesis, after Pierre Duhem and W.V. Quine, it is impossible to test a theory in isolation. One must always add auxiliary hypotheses in order to make testable predictions. For example, to test Newton's Law of Gravitation in the solar system, one needs information about the masses and positions of the Sun and all the planets. Famously, the failure to predict the orbit of Uranus in the 19th century led not to the rejection of Newton's Law but rather to the rejection of the hypothesis that the solar system comprises only seven planets. The investigations that followed led to the discovery of an eighth planet, Neptune. If a test fails, something is wrong. But there is a problem in figuring out what that something is: a missing planet, badly calibrated test equipment, an unsuspected curvature of space, or something else.

One consequence of the Duhem–Quine thesis is that one can make any theory compatible with any empirical observation by the addition of a sufficient number of suitable ad hoc hypotheses. Karl Popper accepted this thesis, leading him to reject naïve falsification. Instead, he favored a "survival of the fittest" view in which the most falsifiable scientific theories are to be preferred.

Anything goes methodology

Paul Feyerabend (1924–1994) argued that no description of scientific method could possibly be broad enough to include all the approaches and methods used by scientists, and that there are no useful and exception-free methodological rules governing the progress of science. He argued that "the only principle that does not inhibit progress is: anything goes".

Feyerabend said that science started as a liberating movement, but that over time it had become increasingly dogmatic and rigid and had some oppressive features, and thus had become increasingly an ideology. Because of this, he said it was impossible to come up with an unambiguous way to distinguish science from religion, magic, or mythology. He saw the exclusive dominance of science as a means of directing society as authoritarian and ungrounded. Promulgation of this epistemological anarchism earned Feyerabend the title of "the worst enemy of science" from his detractors.

Sociology of scientific knowledge methodology

According to Kuhn, science is an inherently communal activity which can only be done as part of a community. For him, the fundamental difference between science and other disciplines is the way in which the communities function. Others, especially Feyerabend and some post-modernist thinkers, have argued that there is insufficient difference between social practices in science and other disciplines to maintain this distinction. For them, social factors play an important and direct role in scientific method, but they do not serve to differentiate science from other disciplines. On this account, science is socially constructed, though this does not necessarily imply the more radical notion that reality itself is a social construct.

However, some (such as Quine) do maintain that scientific reality is a social construct:

Physical objects are conceptually imported into the situation as convenient intermediaries not by definition in terms of experience, but simply as irreducible posits comparable, epistemologically, to the gods of Homer ... For my part I do, qua lay physicist, believe in physical objects and not in Homer's gods; and I consider it a scientific error to believe otherwise. But in point of epistemological footing, the physical objects and the gods differ only in degree and not in kind. Both sorts of entities enter our conceptions only as cultural posits.

The public backlash of scientists against such views, particularly in the 1990s, became known as the science wars.

A major development in recent decades has been the study of the formation, structure, and evolution of scientific communities by sociologists and anthropologists – including David Bloor, Harry Collins, Bruno Latour, Ian Hacking and Anselm Strauss. Concepts and methods (such as rational choice, social choice or game theory) from economics have also been applied for understanding the efficiency of scientific communities in the production of knowledge. This interdisciplinary field has come to be known as science and technology studies. Here the approach to the philosophy of science is to study how scientific communities actually operate.

Continental philosophy

Philosophers in the continental philosophical tradition are not traditionally categorized as philosophers of science. However, they have much to say about science, some of which has anticipated themes in the analytical tradition. For example, Friedrich Nietzsche advanced the thesis in his The Genealogy of Morals (1887) that the motive for the search for truth in sciences is a kind of ascetic ideal.

Hegel with his Berlin students
Sketch by Franz Kugler

In general, continental philosophy views science from a world-historical perspective. Georg Wilhelm Friedrich Hegel (1770-1831) became one of the first philosophers to support this view. Philosophers such as Pierre Duhem (1861-1916) and Gaston Bachelard (1884-1962) also wrote their works with this world-historical approach to science, predating Kuhn's 1962 work by a generation or more. All of these approaches involve a historical and sociological turn to science, with a priority on lived experience (a kind of Husserlian "life-world"), rather than a progress-based or anti-historical approach as emphasised in the analytic tradition. One can trace this continental strand of thought through the phenomenology of Edmund Husserl (1859-1938), the late works of Merleau-Ponty (Nature: Course Notes from the Collège de France, 1956–1960), and the hermeneutics of Martin Heidegger (1889-1976).

The largest effect on the continental tradition with respect to science came from Martin Heidegger's critique of the theoretical attitude in general, which of course includes the scientific attitude. For this reason, the continental tradition has remained much more skeptical of the importance of science in human life and in philosophical inquiry. Nonetheless, there have been a number of important works: especially those of a Kuhnian precursor, Alexandre Koyré (1892-1964). Another important development was that of Michel Foucault's analysis of historical and scientific thought in The Order of Things (1966) and his study of power and corruption within the "science" of madness. Post-Heideggerian authors contributing to continental philosophy of science in the second half of the 20th century include Jürgen Habermas (e.g., Truth and Justification, 1998), Carl Friedrich von Weizsäcker (The Unity of Nature, 1980; German: Die Einheit der Natur (1971)), and Wolfgang Stegmüller (Probleme und Resultate der Wissenschaftstheorie und Analytischen Philosophie, 1973–1986).

Other topics

Reductionism

Analysis involves breaking an observation or theory down into simpler concepts in order to understand it. Reductionism can refer to one of several philosophical positions related to this approach. One type of reductionism suggests that phenomena are amenable to scientific explanation at lower levels of analysis and inquiry. Perhaps a historical event might be explained in sociological and psychological terms, which in turn might be described in terms of human physiology, which in turn might be described in terms of chemistry and physics. Daniel Dennett distinguishes legitimate reductionism from what he calls greedy reductionism, which denies real complexities and leaps too quickly to sweeping generalizations.

Social accountability

A broad issue affecting the neutrality of science concerns the areas which science chooses to explore, that is, what part of the world and of humankind are studied by science. Philip Kitcher in his Science, Truth, and Democracy argues that scientific studies that attempt to show one segment of the population as being less intelligent, successful or emotionally backward compared to others have a political feedback effect which further excludes such groups from access to science. Thus such studies undermine the broad consensus required for good science by excluding certain people, and so proving themselves in the end to be unscientific.

Philosophy of particular sciences

There is no such thing as philosophy-free science; there is only science whose philosophical baggage is taken on board without examination.

— Daniel Dennett, Darwin's Dangerous Idea, 1995

In addition to addressing the general questions regarding science and induction, many philosophers of science are occupied by investigating foundational problems in particular sciences. They also examine the implications of particular sciences for broader philosophical questions. The late 20th and early 21st century has seen a rise in the number of practitioners of philosophy of a particular science.

Philosophy of statistics

The problem of induction discussed above is seen in another form in debates over the foundations of statistics. The standard approach to statistical hypothesis testing avoids claims about whether evidence supports a hypothesis or makes it more probable. Instead, the typical test yields a p-value, which is the probability of the evidence being such as it is, under the assumption that the hypothesis being tested is true. If the p-value is too low, the hypothesis is rejected, in a way analogous to falsification. In contrast, Bayesian inference seeks to assign probabilities to hypotheses. Related topics in philosophy of statistics include probability interpretations, overfitting, and the difference between correlation and causation.

Philosophy of mathematics

Philosophy of mathematics is concerned with the philosophical foundations and implications of mathematics. The central questions are whether numbers, triangles, and other mathematical entities exist independently of the human mind and what is the nature of mathematical propositions. Is asking whether "1+1=2" is true fundamentally different from asking whether a ball is red? Was calculus invented or discovered? A related question is whether learning mathematics requires experience or reason alone. What does it mean to prove a mathematical theorem and how does one know whether a mathematical proof is correct? Philosophers of mathematics also aim to clarify the relationships between mathematics and logic, human capabilities such as intuition, and the material universe.

Philosophy of physics

Unsolved problem in physics:

How does the quantum description of reality, which includes elements such as the "superposition of states" and "wavefunction collapse", give rise to the reality we perceive?

Philosophy of physics is the study of the fundamental, philosophical questions underlying modern physics, the study of matter and energy and how they interact. The main questions concern the nature of space and time, atoms and atomism. Also included are the predictions of cosmology, the interpretation of quantum mechanics, the foundations of statistical mechanics, causality, determinism, and the nature of physical laws. Classically, several of these questions were studied as part of metaphysics (for example, those about causality, determinism, and space and time).

Philosophy of chemistry

Philosophy of chemistry is the philosophical study of the methodology and content of the science of chemistry. It is explored by philosophers, chemists, and philosopher-chemist teams. It includes research on general philosophy of science issues as applied to chemistry. For example, can all chemical phenomena be explained by quantum mechanics or is it not possible to reduce chemistry to physics? For another example, chemists have discussed the philosophy of how theories are confirmed in the context of confirming reaction mechanisms. Determining reaction mechanisms is difficult because they cannot be observed directly. Chemists can use a number of indirect measures as evidence to rule out certain mechanisms, but they are often unsure if the remaining mechanism is correct because there are many other possible mechanisms that they have not tested or even thought of. Philosophers have also sought to clarify the meaning of chemical concepts which do not refer to specific physical entities, such as chemical bonds.

Philosophy of astronomy

The philosophy of astronomy seeks to understand and analyze the methodologies and technologies utilized by experts in the discipline, focusing on how observations made about space and astrophysical phenomena can be studied. Given that astronomers rely and utilize theories and formulas from other scientific disciplines, such as chemistry and physics, the pursuit of understanding how knowledge can be obtained about the cosmos, as well as the relation in which our planet and Solar System have within our personal views of our place in the universe, philosophical insights into how facts about space can be scientifically analyzed and configure with other established knowledge is a main point of inquiry.

Philosophy of Earth sciences

The philosophy of Earth science is concerned with how humans obtain and verify knowledge of the workings of the Earth system, including the atmosphere, hydrosphere, and geosphere (solid earth). Earth scientists’ ways of knowing and habits of mind share important commonalities with other sciences, but also have distinctive attributes that emerge from the complex, heterogeneous, unique, long-lived, and non-manipulatable nature of the Earth system.

Philosophy of biology

Peter Godfrey-Smith was awarded the Lakatos Award for his 2009 book Darwinian Populations and Natural Selection, which discusses the philosophical foundations of the theory of evolution.

Philosophy of biology deals with epistemological, metaphysical, and ethical issues in the biological and biomedical sciences. Although philosophers of science and philosophers generally have long been interested in biology (e.g., Aristotle, Descartes, Leibniz and even Kant), philosophy of biology only emerged as an independent field of philosophy in the 1960s and 1970s. Philosophers of science began to pay increasing attention to developments in biology, from the rise of the modern synthesis in the 1930s and 1940s to the discovery of the structure of deoxyribonucleic acid (DNA) in 1953 to more recent advances in genetic engineering. Other key ideas such as the reduction of all life processes to biochemical reactions as well as the incorporation of psychology into a broader neuroscience are also addressed. Research in current philosophy of biology includes investigation of the foundations of evolutionary theory (such as Peter Godfrey-Smith's work), and the role of viruses as persistent symbionts in host genomes. As a consequence, the evolution of genetic content order is seen as the result of competent genome editors in contrast to former narratives in which error replication events (mutations) dominated.

Philosophy of medicine

A fragment of the Hippocratic Oath from the third century.

Beyond medical ethics and bioethics, the philosophy of medicine is a branch of philosophy that includes the epistemology and ontology/metaphysics of medicine. Within the epistemology of medicine, evidence-based medicine (EBM) (or evidence-based practice (EBP)) has attracted attention, most notably the roles of randomisation, blinding and placebo controls. Related to these areas of investigation, ontologies of specific interest to the philosophy of medicine include Cartesian dualism, the monogenetic conception of disease and the conceptualization of 'placebos' and 'placebo effects'. There is also a growing interest in the metaphysics of medicine, particularly the idea of causation. Philosophers of medicine might not only be interested in how medical knowledge is generated, but also in the nature of such phenomena. Causation is of interest because the purpose of much medical research is to establish causal relationships, e.g. what causes disease, or what causes people to get better.

Philosophy of psychiatry

Philosophy of psychiatry explores philosophical questions relating to psychiatry and mental illness. The philosopher of science and medicine Dominic Murphy identifies three areas of exploration in the philosophy of psychiatry. The first concerns the examination of psychiatry as a science, using the tools of the philosophy of science more broadly. The second entails the examination of the concepts employed in discussion of mental illness, including the experience of mental illness, and the normative questions it raises. The third area concerns the links and discontinuities between the philosophy of mind and psychopathology.

Philosophy of psychology

Philosophy of psychology refers to issues at the theoretical foundations of modern psychology. Some of these issues are epistemological concerns about the methodology of psychological investigation. For example, is the best method for studying psychology to focus only on the response of behavior to external stimuli or should psychologists focus on mental perception and thought processes? If the latter, an important question is how the internal experiences of others can be measured. Self-reports of feelings and beliefs may not be reliable because, even in cases in which there is no apparent incentive for subjects to intentionally deceive in their answers, self-deception or selective memory may affect their responses. Then even in the case of accurate self-reports, how can responses be compared across individuals? Even if two individuals respond with the same answer on a Likert scale, they may be experiencing very different things.

Other issues in philosophy of psychology are philosophical questions about the nature of mind, brain, and cognition, and are perhaps more commonly thought of as part of cognitive science, or philosophy of mind. For example, are humans rational creatures? Is there any sense in which they have free will, and how does that relate to the experience of making choices? Philosophy of psychology also closely monitors contemporary work conducted in cognitive neuroscience, evolutionary psychology, and artificial intelligence, questioning what they can and cannot explain in psychology.

Philosophy of psychology is a relatively young field, because psychology only became a discipline of its own in the late 1800s. In particular, neurophilosophy has just recently become its own field with the works of Paul Churchland and Patricia Churchland. Philosophy of mind, by contrast, has been a well-established discipline since before psychology was a field of study at all. It is concerned with questions about the very nature of mind, the qualities of experience, and particular issues like the debate between dualism and monism.

Philosophy of archaeology

The philosophy of archaeology seeks to investigate the foundations, methods and implications of the discipline of archaeology in order to further understanding of the human past and present. Central questions include what is archaeology? What is the theoretical basis of archaeology? How should archaeology conceive of time? Why, and for who, is archaeology practiced. What is the nature and reality of the objects and processes of archaeological study? Analytic philosophy of archaeology investigates the logic behind concepts such as artefact, site, the archaeological record and archaeological cultures. These are just some examples of the metaphysical, aesthetic, epistemological, ethical and theoretical concerns at the heart of the practice of archaeology.

Philosophy of anthropology

The philosophy of anthropology is a branch of philosophy dealing with questions of metaphysics and phenomenology of the human person. By analyzing the philosophical factors of what it means to be human, such as cultural, biological, historical, and linguistic variables, the pursuit of trying to understand the question of what it means to be human is viewed in a holistic manner.

Philosophy of geography

The philosophy of geography is a subfield of the philosophy of science which deals with epistemological, metaphysical, and axiological issues in geography, with geographic methodology in general, and with more broadly related issues such as the perception and representation of space and place.

Philosophy of linguistics

The philosophy of linguistics is a branch of the philosophy of science that seeks to comprehend and analyze matters of meaning and reference within languages and dialects. Specific topics within this discipline include issues in language learnability, language change, the competence-performance distinction, and the expressive power of linguistic theories.

Philosophy of economics

Amartya Sen was awarded the Nobel Prize in Economics for "combining tools from economics and philosophy."

Philosophy of economics is the branch of philosophy which studies philosophical issues relating to economics. It can also be defined as the branch of economics which studies its own foundations and morality. It can be categorized into three central topics. The first concerns the definition and scope of economics and by what methods it should be studied and whether these methods rise to the level of epistemic reliability associated with the other special sciences. For example, is it possible to research economics in such a way that it is value-free, establishing facts that are independent of the normative views of the researcher? The second topic is the meaning and implications of rationality. For example, can buying lottery tickets (increasing the riskiness of your income) at the same time as buying insurance (decreasing the riskiness of your income) be rational? The third topic is the normative evaluation of economic policies and outcomes. What criteria should be used to determine whether a given public policy is beneficial for society?

Philosophy of social science

The philosophy of social science is the study of the logic and method of the social sciences, such as sociology and political science. Philosophers of social science are concerned with the differences and similarities between the social and the natural sciences, causal relationships between social phenomena, the possible existence of social laws, and the ontological significance of structure and agency.

The French philosopher, Auguste Comte (1798–1857), established the epistemological perspective of positivism in The Course in Positivist Philosophy, a series of texts published between 1830 and 1842. The first three volumes of the Course dealt chiefly with the natural sciences already in existence (geoscience, astronomy, physics, chemistry, biology), whereas the latter two emphasised the inevitable coming of social science: "sociologie". For Comte, the physical sciences had necessarily to arrive first, before humanity could adequately channel its efforts into the most challenging and complex "Queen science" of human society itself. Comte offers an evolutionary system proposing that society undergoes three phases in its quest for the truth according to a general 'law of three stages'. These are (1) the theological, (2) the metaphysical, and (3) the positive.

Comte's positivism established the initial philosophical foundations for formal sociology and social research. Durkheim, Marx, and Weber are more typically cited as the fathers of contemporary social science. In psychology, a positivistic approach has historically been favoured in behaviourism. Positivism has also been espoused by 'technocrats' who believe in the inevitability of social progress through science and technology.

The positivist perspective has been associated with 'scientism'; the view that the methods of the natural sciences may be applied to all areas of investigation, be it philosophical, social scientific, or otherwise. Among most social scientists and historians, orthodox positivism has long since lost popular support. Today, practitioners of both social and physical sciences instead take into account the distorting effect of observer bias and structural limitations. This scepticism has been facilitated by a general weakening of deductivist accounts of science by philosophers such as Thomas Kuhn, and new philosophical movements such as critical realism and neopragmatism. The philosopher-sociologist Jürgen Habermas has critiqued pure instrumental rationality as meaning that scientific-thinking becomes something akin to ideology itself.

Philosophy of technology

The philosophy of technology is a sub-field of philosophy that studies the nature of technology. Specific research topics include study of the role of tacit and explicit knowledge in creating and using technology, the nature of functions in technological artifacts, the role of values in design, and ethics related to technology. Technology and engineering can both involve the application of scientific knowledge. The philosophy of engineering is an emerging sub-field of the broader philosophy of technology.
