Secularism

From Wikipedia, the free encyclopedia
 
Secularism is the principle of the separation of government institutions and persons mandated to represent the state from religious institution and religious dignitaries (the attainment of such is termed secularity). One manifestation of secularism is asserting the right to be free from religious rule and teachings, or, in a state declared to be neutral on matters of belief, from the imposition by government of religion or religious practices upon its people. Another manifestation of secularism is the view that public activities and decisions, especially political ones, should be uninfluenced by religious beliefs or practices.

Secularism draws its intellectual roots from Greek and Roman philosophers such as Epicurus and Marcus Aurelius; from Enlightenment thinkers such as John Locke, Denis Diderot, Voltaire, Baruch Spinoza, James Madison, Thomas Jefferson, and Thomas Paine; and from more recent freethinkers and atheists such as Robert Ingersoll, Bertrand Russell, and Christopher Hitchens. It shifts the focus from religion to other ‘temporal’ and ‘this-worldly’ things with emphasis on nature, reason, science, and development.[2]

The purposes and arguments in support of secularism vary widely.[3] In European laicism, it has been argued that secularism is a movement toward modernization, and away from traditional religious values (also known as secularization). This type of secularism, on a social or philosophical level, has often occurred while maintaining an official state church or other state support of religion. In the United States, some argue that state secularism has served to a greater extent to protect religion and the religious from governmental interference, while secularism on a social level is less prevalent.[4][5]

Overview

The British writer George Jacob Holyoake (1817–1906) coined the term "secularism" in 1851[6]
 
Italian law professor Alberico Gentili (1552–1608) first split secularism from canon law and Roman Catholic theology.

The term "secularism" was first used by the British writer George Jacob Holyoake in 1851.[6] Holyoake invented the term secularism to describe his views of promoting a social order separate from religion, without actively dismissing or criticizing religious belief. An agnostic himself, Holyoake argued that "Secularism is not an argument against Christianity, it is one independent of it. It does not question the pretensions of Christianity; it advances others. Secularism does not say there is no light or guidance elsewhere, but maintains that there is light and guidance in secular truth, whose conditions and sanctions exist independently, and act forever. Secular knowledge is manifestly that kind of knowledge which is founded in this life, which relates to the conduct of this life, conduces to the welfare of this life, and is capable of being tested by the experience of this life."[7]

Barry Kosmin of the Institute for the Study of Secularism in Society and Culture breaks modern secularism into two types: hard and soft secularism. According to Kosmin, "the hard secularist considers religious propositions to be epistemologically illegitimate, warranted by neither reason nor experience." However, in the view of soft secularism, "the attainment of absolute truth was impossible and therefore skepticism and tolerance should be the principle and overriding values in the discussion of science and religion."[8]

History

The departure from reliance on religious faith to reason and science marks the beginning of the secularization of education and society in history. According to Domenic Marbaniang, Secularism emerged in the West with the establishment of reason over religious faith as human reason was gradually liberated from unquestioned subjection to the dominion of religion and superstition.[9] Secularism first appeared in the West in the classical philosophy and politics of ancient Greece, disappeared for a time after the fall of Greece, but resurfaced after a millennium and half in the Renaissance and the Reformation. He writes:
An increasing confidence in human capabilities, reason, and progress, that emerged during the Italian Renaissance, together with an increasing distrust in organized and state supported religion during the Reformation, was responsible for the ushering of modernity during the Enlightenment, which brought all facets of human life including religion under the purview of reason and thus became responsible for the freeing of education, society, and state from the domination of religion; in other words, the development of modern secularism.[10]
Harvey Cox explains that the Enlightenment hailed Nature as the "deep reality" that transcended the corrupted man-made institutions of men. Consequently, the rights of man were not considered as God-given but as the de facto benefits of Nature as revealed by Reason.[11]

State secularism

In political terms, secularism is a movement towards the separation of religion and government (often termed the separation of church and state). This can refer to reducing ties between a government and a state religion, replacing laws based on scripture (such as Halakha, Dominionism, and Sharia law) with civil laws, and eliminating discrimination on the basis of religion. This is said to add to democracy by protecting the rights of religious minorities.[12]

In his On Temporal Authority (1523), Martin Luther argued for the division of the church and the state. He specified two distinct powers: weltliches Regiment (German word for ‘the kingdom of the world,’ ‘the State’) and geistliches Regiment (German word for ‘the kingdom of God,’ ‘the Church’) and argued that citizens need only subject to the ruler's edict as long as the edict conformed to God's divine will as revealed in the scriptures.[13]

Scholars, such as Jacques Berlinerblau of the Program for Jewish Civilization at the Edmund A. Walsh School of Foreign Service at Georgetown University, have argued that the separation of church and state is but one possible strategy to be deployed by secular governments. What all secular governments, from the democratic to the authoritarian, share is a concern about the relationship between the church and the state. Each secular government may find its own unique policy prescriptions for dealing with that concern (separation being one of those possible policies; French models, in which the state carefully monitors and regulates the church, being another).[14]

A major impact on the idea of state religious liberty came from the writings of John Locke who, in his A Letter Concerning Toleration argued in favor of religious toleration. He argued that government must treat all citizens and all religions equally and that it can restrict actions but not the religious intent behind them.[15]

Maharaja Ranjeet Singh of the Sikh empire of the first half of the 19th century successfully established a secular rule in the Punjab. This secular rule respected members of all races and religions and it allowed them to participate without discrimination in Ranjeet Singh's darbar and he had Sikh, Muslim and Hindu representatives heading the darbar.[16] Ranjit Singh also extensively funded education, religion, and arts of various different religions and languages.[17]

Secularism is most often associated with the Age of Enlightenment in Europe and it plays a major role in Western society. The principles, but not necessarily the practices, of separation of church and state in the United States and Laïcité in France draw heavily on secularism. Secular states also existed in the Islamic world during the Middle Ages (see Islam and secularism).[18]

Due in part to the belief in the separation of church and state, secularists tend to prefer that politicians make decisions for secular rather than religious reasons.[19] In this respect, policy decisions pertaining to topics like abortion, contraception, embryonic stem cell research, same-sex marriage, and sex education are prominently focused upon by American secularist organizations such as the Center for Inquiry.[20][21]

Some Christian fundamentalists (notably in the United States) oppose secularism, often claiming that there is a "radical secularist" ideology being adopted in our current day and they see secularism as a threat to "Christian rights"[22] and national security.[23] The most significant forces of religious fundamentalism in the contemporary world are Christian fundamentalism and Islamic fundamentalism. At the same time, one significant stream of secularism has come from religious minorities who see governmental and political secularism as integral to the preservation of equal rights.[24]

Some of the well known states that are often considered "constitutionally secular" are the United States,[25] France,[26] Mexico[27] South Korea, and Turkey although none of these nations have identical forms of governance with respect to religion.

Secular society

In studies of religion, modern democracies are generally recognized as secular. This is due to the near-complete freedom of religion (beliefs on religion generally are not subject to legal or social sanctions), and the lack of authority of religious leaders over political decisions. Nevertheless, it has been claimed that surveys done by Pew Research Center show Americans as generally being more comfortable with religion playing a major role in public life, while in Europe the impact of the church on public life is declining.[28]

The aspirations of a secular society could characterize a society as one which:
  1. Refuses to commit itself as a whole to any supernatural views of the nature of the universe, or the role of mankind in it.
  2. Is not homogeneous, but is pluralistic.
  3. Is very tolerant of religious diversity. It widens the sphere of private decision-making.
  4. While every society must have some common aims, which implies there must be agreed upon methods of problem-solving, and a common framework of law; in a secular society these are as limited as possible.
  5. Problem solving is approached rationally, through examination of the facts. While the secular society does not set any overall aim, it helps its members realize their shared aims.
  6. Is a society without any official images. Nor is there a common ideal type of behavior with universal application.
Positive Ideals behind the secular society:
  1. Respect for individuals and the small groups of which they are a part.
  2. Equality of all people.
  3. Each person should be free to realize their particular excellence.
  4. Breaking down of the barriers of class and caste.[29]
Modern sociology has, since Max Weber, often been preoccupied with the problem of authority in secularized societies and with secularization as a sociological or historical process.[30] Twentieth-century scholars, whose work has contributed to the understanding of these matters, include Carl L. Becker, Karl Löwith, Hans Blumenberg, M. H. Abrams, Peter L. Berger, Paul Bénichou and D. L. Munby, among others.

Some societies become increasingly secular as the result of social processes, rather than through the actions of a dedicated secular movement; this process is known as secularization.

Sociologist Peter L. Berger maintained that the modern world can no longer be described as being secular or becoming increasingly secular, instead it can best be described as being pluralistic. [31]

Secular ethics

George Holyoake's 1896 publication English Secularism describes secularism as follows:
Secularism is a code of duty pertaining to this life, founded on considerations purely human, and intended mainly for those who find theology indefinite or inadequate, unreliable or unbelievable. Its essential principles are three: (1) The improvement of this life by material means. (2) That science is the available Providence of man. (3) That it is good to do good. Whether there be other good or not, the good of the present life is good, and it is good to seek that good.[32]
Holyoake held that secularism and secular ethics should take no interest at all in religious questions (as they were irrelevant), and was thus to be distinguished from strong freethought and atheism. In this he disagreed with Charles Bradlaugh, and the disagreement split the secularist movement between those who argued that anti-religious movements and activism was not necessary or desirable and those who argued that it was.

Contemporary ethical debate in the West is often described as "secular." The work of well known moral philosophers such as Derek Parfit and Peter Singer, and even the whole field of contemporary bioethics, have been described as explicitly secular or non-religious.[33][34][35][36]

American interpretation of secularism

It has been argued that the concept of secularism has frequently been misinterpreted.[37] In a July 2012 Huffington Post article titled Secularism Is Not Atheism, Jacques Berlinerblau, Director of the Program for Jewish Civilization at Georgetown University, wrote that "Secularism must be the most misunderstood and mangled ism in the American political lexicon. Commentators on the right and the left routinely equate it with Stalinism, Nazism and Socialism, among other dreaded isms. In the United States, of late, another false equation has emerged. That would be the groundless association of secularism with atheism. The religious right has profitably promulgated this misconception at least since the 1970s."[37]

Secularism in late 20th century political philosophy

It can be seen by many of the organizations (NGO's) for secularism that they prefer to define secularism as the common ground for all life stance groups, religious or atheistic, to thrive in a society that honors freedom of speech and conscience. An example of that is the National Secular Society in the UK. This is a common understanding of what secularism stands for among many of its activists throughout the world. However, many scholars of Christianity and conservative politicians seem to interpret secularism more often than not, as an antithesis of religion and an attempt to push religion out of society and replace it with atheism or a void of values, nihilism. This dual aspect (as noted above in "Secular ethics") has created difficulties in political discourse on the subject. It seems that most political theorists in philosophy following the landmark work of John Rawl´s Theory of Justice in 1971 and its following book, Political Liberalism (1993),[38] would rather use the conjoined concept overlapping consensus rather than secularism. In the latter Rawls holds the idea of an overlapping consensus as one of three main ideas of political liberalism. He argues that the term secularism cannot apply;
But what is a secular argument? Some think of any argument that is reflective and critical, publicly intelligible and rational, as a secular argument; [...], Nevertheless, a central feature of political liberalism is that it views all such arguments the same way it views religious ones, and therefore these secular philosophical doctrines do not provide public reasons. Secular concepts and reasoning of this kind belong to first philosophy and moral doctrine, and fall outside the domain of the political.[38]
Still, Rawl´s theory is akin to Holyoake´s vision of a tolerant democracy that treats all life stance groups alike. Rawl´s idea it that it is in everybody´s own interest to endorse "a reasonable constitutional democracy" with "principles of toleration". His work has been highly influential on scholars in political philosophy and his term, overlapping consensus, seems to have for many parts replaced secularism among them. In textbooks on modern political philosophy, like Colin Farelly´s, An Introduction to Contemporary Political Theory,[39] and Will Kymlicka´s, Contemporary Political Philosophy,[40] the term secularism is not even indexed and in the former it can be seen only in one footnote. However, there is no shortage of discussion and coverage of the topic it involves. It is just called overlapping consensus, pluralism, multiculturalism or expressed in some other way. In The Oxford Handbook of Political Theory,[41] there is one chapter called "Political secularism", by Rajeev Bhargava. It covers secularism in a global context and starts with this sentence: "Secularism is a beleaguered doctrine."

Organizations

Groups such as the National Secular Society (United Kingdom) and Americans United campaign for secularism are often supported by Humanists. In 2005, the National Secular Society held the inaugural "Secularist of the Year" awards ceremony. The award's first winner was Maryam Namazie, of the Worker-Communist Party of Iran and the Council of Ex-Muslims of Britain[42] which aims to break the taboo that comes with renouncing Islam and to oppose apostasy laws and political Islam.[43]
The Scottish Secular Society is active in Scotland and is currently focused on the role of religion in education. In 2013 it raised a petition at the Scottish Parliament to have the Education (Scotland) Act 1980 changed so that parents will have to make a positive choice to opt into Religious Observance.

Another secularist organization is the Secular Coalition for America. The Secular Coalition for America lobbies and advocates for separation of church and state as well as the acceptance and inclusion of Secular Americans in American life and public policy. While Secular Coalition for America is linked to many secular humanistic organizations and many secular humanists support it, as with the Secular Society, some non-humanists support it.

Local organizations work to raise the profile of secularism in their communities and tend to include secularists, freethinkers, atheists, agnostics, and humanists under their organizational umbrella.

Student organizations, such as the Toronto Secular Alliance, try to popularize nontheism and secularism on campus. The Secular Student Alliance is an educational nonprofit that organizes and aids such high school and college secular student groups.

In Turkey, the most prominent and active secularist organization is Atatürkist Thought Association (ADD), which is credited for organizing the Republic Protests – demonstrations in the four largest cities in Turkey in 2007, where over 2 million people, mostly women, defended their concern in and support of secularist principles introduced by Mustafa Kemal Atatürk.

Leicester Secular Society founded in 1851 is the world's oldest secular society.

Saturn moon Titan has chemical that could form bio-like ‘membranes’ says NASA

Cassini spacecraft also discovered "carbon chain anions" in Titan’s upper atmosphere that may be building blocks for more complex organic molecules.

Molecules of vinyl cyanide reside in the atmosphere of Titan, Saturn’s largest moon, says NASA. Titan is shown here in an optical (atmosphere) infrared (surface) composite from NASA’s Cassini spacecraft. Titan’s atmosphere is a veritable chemical factory, harnessing the light of the sun and the energy from fast-moving particles that orbit around Saturn to convert simple organic molecules into larger, more complex chemicals.

NASA researchers have found large quantities (2.8 parts per billion) of acrylonitrile* (vinyl cyanide, C2H3CN) in Titan’s atmosphere that could self-assemble as a sheet of material similar to a cell membrane.

Consider these findings, presented July 28, 2017 in the open-access journal Science Advances, based on data from the ALMA telescope in Chile (and confirming earlier observations by NASA’s Cassini spacecraft):

1. Researchers have proposed that acrylonitrile molecules could come together as a sheet of material similar to a cell membrane. The sheet could form a hollow, microscopic sphere that they dubbed an “azotosome.”

2. The azotosome sphere could serve as a tiny storage and transport container, much like the spheres that biological lipid bilayers can form. The thin, flexible lipid bilayer is the main component of the cell membrane, which separates the inside of a cell from the outside world.

“The ability to form a stable membrane to separate the internal environment from the external one is important because it provides a means to contain chemicals long enough to allow them to interact,” said Michael Mumma, director of the Goddard Center for Astrobiology, which is funded by the NASA Astrobiology Institute.

3. Acrylonitrile condenses in the cold lower atmosphere and rains onto its solid icy surface, ending up in seas of methane liquids on its surface.

4. A lake on Titan named Ligeia Mare that could have accumulated enough acrylonitrile to form about 10 million azotosomes in every milliliter (quarter-teaspoon) of liquid. Compare that to roughly a million bacteria per milliliter of coastal ocean water on Earth.

Chemistry in Titan’s atmosphere. Nearly as large as Mars, Titan has a hazy atmosphere made up mostly of nitrogen with a smattering of organic, carbon-based molecules, including methane (CH4) and ethane (C2H6). Planetary scientists theorize that this chemical make-up is similar to Earth’s primordial atmosphere. The conditions on Titan, however, are not conducive to the formation of life as we know it; it’s simply too cold (95 kelvins or -290 degrees Fahrenheit). (credit: ESA)

5. A related open-access study published July 26, 2017 in The Astrophysical Journal Letters notes that Cassini has also made the surprising detection of negatively charged molecules known as “carbon chain anions” in Titan’s upper atmosphere. These molecules are understood to be building blocks towards more complex molecules, and may have acted as the basis for the earliest forms of life on Earth.

“This is a known process in the interstellar medium, but now we’ve seen it in a completely different environment, meaning it could represent a universal process for producing complex organic molecules,” says Ravi Desai of University College London and lead author of the study.

Abstract of ALMA detection and astrobiological potential of vinyl cyanide on Titan

Recent simulations have indicated that vinyl cyanide is the best candidate molecule for the formation of cell membranes/vesicle structures in Titan’s hydrocarbon-rich lakes and seas. Although the existence of vinyl cyanide (C2H3CN) on Titan was previously inferred using Cassini mass spectrometry, a definitive detection has been lacking until now. We report the first spectroscopic detection of vinyl cyanide in Titan’s atmosphere, obtained using archival data from the Atacama Large Millimeter/submillimeter Array (ALMA), collected from February to May 2014. We detect the three strongest rotational lines of C2H3CN in the frequency range of 230 to 232 GHz, each with >4σ confidence. Radiative transfer modeling suggests that most of the C2H3CN emission originates at altitudes of ≳200 km, in agreement with recent photochemical models. The vertical column densities implied by our best-fitting models lie in the range of 3.7 × 1013 to 1.4 × 1014 cm−2. The corresponding production rate of vinyl cyanide and its saturation mole fraction imply the availability of sufficient dissolved material to form ~107 cell membranes/cm3 in Titan’s sea Ligeia Mare.

New solar power nanotechnology material converts 90 percent of captured light into heat

(Nanowerk News) A multidisciplinary engineering team at the University of California, San Diego developed a new nanoparticle-based material for concentrating solar power plants designed to absorb and convert to heat more than 90 percent of the sunlight it captures. The new material can also withstand temperatures greater than 700 degrees Celsius and survive many years outdoors in spite of exposure to air and humidity. Their work, funded by the U.S. Department of Energy's SunShot program, was published recently in two separate articles in the journal Nano Energy ("Tandem structured spectrally selective coating layer of copper oxide nanowires combined with cobalt oxide nanoparticles").

By contrast, current solar absorber material functions at lower temperatures and needs to be overhauled almost every year for high temperature operations.

Engineers at UC San Diego have developed a nanoparticle-based material for concentrating solar power plants that converts 90% of captured sunlight to heat. With particle sizes ranging from 10 nanometers to 10 micrometers, the multiscale structure traps and absorbs light more efficiently and at temperatures greater than 700 degrees Celsius.

"We wanted to create a material that absorbs sunlight that doesn't let any of it escape. We want the black hole of sunlight," said Sungho Jin, a professor in the department of Mechanical and Aerospace Engineering at UC San Diego Jacobs School of Engineering. Jin, along with professor Zhaowei Liu of the department of Electrical and Computer Engineering, and Mechanical Engineering professor Renkun Chen, developed the Silicon boride-coated nanoshell material. They are all experts in functional materials engineering.

The novel nanotechnology material features a "multiscale" surface created by using particles of many sizes ranging from 10 nanometers to 10 micrometers. The multiscale structures can trap and absorb light which contributes to the material's high efficiency when operated at higher temperatures.

Concentrating solar power (CSP) is an emerging alternative clean energy market that produces approximately 3.5 gigawatts worth of power at power plants around the globe—enough to power more than 2 million homes, with additional construction in progress to provide as much as 20 gigawatts of power in coming years. One of the technology's attractions is that it can be used to retrofit existing power plants that use coal or fossil fuels because it uses the same process to generate electricity from steam.

Traditional power plants burn coal or fossil fuels to create heat that evaporates water into steam. The steam turns a giant turbine that generates electricity from spinning magnets and conductor wire coils. CSP power plants create the steam needed to turn the turbine by using sunlight to heat molten salt. The molten salt can also be stored in thermal storage tanks overnight where it can continue to generate steam and electricity, 24 hours a day if desired, a significant advantage over photovoltaic systems that stop producing energy with the sunset.

Spray-Painting
UC San Diego mechanical engineering professor Renkun Chen spray paints a novel material designed that could significantly improve the cost competitiveness of solar energy by converting more than 90 percent of the sunlight it captures into heat. Funded by the US Department of Energy's SunShot Initiative, the team is tasked with coming up with a material that can last for years in the air and humidity before it needs to be repainted, a feat the team believes it is close to achieving. (Image: David Baillot/UC San Diego Jacobs School of Engineering)

One of the most common types of CSP systems uses more than 100,000 reflective mirrors to aim sunlight at a tower that has been spray painted with a light absorbing black paint material. The material is designed to maximize sun light absorption and minimize the loss of light that would naturally emit from the surface in the form of infrared radiation.

The UC San Diego team's combined expertise was used to develop, optimize and characterize a new material for this type of system over the past three years. Researchers included a group of UC San Diego graduate students in materials science and engineering, Justin Taekyoung Kim, Bryan VanSaders, and Jaeyun Moon, who recently joined the faculty of the University of Nevada, Las Vegas. The synthesized nanoshell material is spray-painted in Chen's lab onto a metal substrate for thermal and mechanical testing. The material's ability to absorb sunlight is measured in Liu's optics laboratory using a unique set of instruments that takes spectral measurements from visible light to infrared.

Current CSP plants are shut down about once a year to chip off the degraded sunlight absorbing material and reapply a new coating, which means no power generation while a replacement coating is applied and cured. That is why DOE's SunShot program challenged and supported UC San Diego research teams to come up with a material with a substantially longer life cycle, in addition to the higher operating temperature for enhanced energy conversion efficiency. The UC San Diego research team is aiming for many years of usage life, a feat they believe they are close to achieving.

Modeled after President Kennedy's moon landing program that inspired widespread interest in science and space exploration, then-Energy Secretary Steven P. Chu launched the Sunshot Initiative in 2010 with the goal of making solar power cost competitive with other means of producing electricity by 2020.

Freethought

From Wikipedia, the free encyclopedia

Freethought (or "free thought") is a philosophical viewpoint which holds that positions regarding truth should be formed on the basis of logic, reason, and empiricism, rather than authority, tradition, revelation, or dogma. In particular, freethought is strongly tied with rejection of traditional social or religious belief systems. The cognitive application of freethought is known as "freethinking", and practitioners of freethought are known as "freethinkers". The term first came into use in the 17th century in order to indicate people who inquired into the basis of traditional religious beliefs.

Definition

Freethinkers hold that knowledge should be grounded in facts, scientific inquiry, and logic. The skeptical application of science implies freedom from the intellectually limiting effects of confirmation bias, cognitive bias, conventional wisdom, popular culture, prejudice, or sectarianism.
Modern freethinkers consider freethought as a natural freedom of all negative and illusive thoughts acquired from the society [5]

Atheist author Adam Lee defines freethought as thinking which is independent of revelation, tradition, established belief, and authority,[6] and considers it as a "broader umbrella" than atheism "that embraces a rainbow of unorthodoxy, religious dissent, skepticism, and unconventional thinking."[7]

The basic summarizing statement of the essay The Ethics of Belief by the 19th-century British mathematician and philosopher William Kingdon Clifford is: "It is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence."[8] The essay became a rallying cry for freethinkers when published in the 1870s, and has been described as a point when freethinkers grabbed the moral high ground.[9] Clifford was himself an organizer of freethought gatherings, the driving force behind the Congress of Liberal Thinkers held in 1878.

Regarding religion, freethinkers typically hold that there is insufficient evidence to support the existence of supernatural phenomena.[10] According to the Freedom from Religion Foundation, "No one can be a freethinker who demands conformity to a bible, creed, or messiah. To the freethinker, revelation and faith are invalid, and orthodoxy is no guarantee of truth." and "Freethinkers are convinced that religious claims have not withstood the tests of reason. Not only is there nothing to be gained by believing an untruth, but there is everything to lose when we sacrifice the indispensable tool of reason on the altar of superstition. Most freethinkers consider religion to be not only untrue, but harmful."[11]

However, philosopher Bertrand Russell wrote the following in his 1944 essay "The Value of Free Thought:"
What makes a freethinker is not his beliefs but the way in which he holds them. If he holds them because his elders told him they were true when he was young, or if he holds them because if he did not he would be unhappy, his thought is not free; but if he holds them because, after careful thought he finds a balance of evidence in their favour, then his thought is free, however odd his conclusions may seem.
— Bertrand Russell, The Value of Free Thought. How to Become a Truth-Seeker and Break the Chains of Mental Slavery, from the first paragraph
The whole first paragraph of the essay makes it clear that a freethinker is not necessarily an atheist or an agnostic, as long as he or she satisfies this definition:
The person who is free in any respect is free from something; what is the free thinker free from? To be worthy of the name, he must be free of two things: the force of tradition, and the tyranny of his own passions. No one is completely free from either, but in the measure of a man's emancipation he deserves to be called a free thinker.
— Bertrand Russell, The Value of Free Thought. How to Become a Truth-Seeker and Break the Chains of Mental Slavery, from the first paragraph
Fred Edwords, former executive of the American Humanist Association, suggests that by Russell's definition, liberal religionists who have challenged established orthodoxies can be considered freethinkers.[12]

On the other hand, according to Bertrand Russell, atheists and/or agnostics are not necessarily freethinkers. As an example, he mentions Stalin, whom he compares to a "pope":
what I am concerned with is the doctrine of the modern Communistic Party, and of the Russian Government to which it owes allegiance. According to this doctrine, the world develops on the lines of a Plan called Dialectical Materialism, first discovered by Karl Marx, embodied in the practice of a great state by Lenin, and now expounded from day to day by a Church of which Stalin is the Pope. […] Free discussion is to be prevented wherever the power to do so exists; […] If this doctrine and this organization prevail, free inquiry will become as impossible as it was in the middle ages, and the world will relapse into bigotry and obscurantism.
— Bertrand Russell, The Value of Free Thought. How to Become a Truth-Seeker and Break the Chains of Mental Slavery
In the 18th and 19th century, many thinkers regarded as freethinkers were deists, arguing that the nature of God can only be known from a study of nature rather than from religious revelation. In the 18th century, "deism" was as much of a 'dirty word' as "atheism", and deists were often stigmatized as either atheists or at least as freethinkers by their Christian opponents.[13][14] Deists today regard themselves as freethinkers, but are now arguably less prominent in the freethought movement than atheists.

Symbol

The pansy, symbol of freethought

The pansy serves as the long-established and enduring symbol of freethought; literature of the American Secular Union inaugurated its usage in the late 1800s. The reasoning behind the pansy as the symbol of freethought lies both in the flower's name and in its appearance. The pansy derives its name from the French word pensée, which means "thought". It allegedly received this name because the flower is perceived by some to bear resemblance to a human face, and in mid-to-late summer it nods forward as if deep in thought.[15]

History

Pre-modern movement

Critical thought has flourished in the Hellenistic Mediterranean, in the repositories of knowledge and wisdom in Ireland and in the Iranian civilizations (for example in the era of Khayyam (1048–1131) and his unorthodox Sufi Rubaiyat poems), and in other civilizations, such as the Chinese (note for example the seafaring renaissance of the Southern Song dynasty of 420–479),[16] and on through heretical thinkers on esoteric alchemy or astrology, to the Renaissance and the Protestant Reformation.

French physician and writer Rabelais celebrated "rabelaisian" freedom as well as good feasting and drinking (an expression and a symbol of freedom of the mind) in defiance of the hypocrisies of conformist orthodoxy in his utopian Thelema Abbey (from θέλημα: free "will"), the device of which was Do What Thou Wilt:
So had Gargantua established it. In all their rule and strictest tie of their order there was but this one clause to be observed, Do What Thou Wilt; because free people ... act virtuously and avoid vice. They call this honor.
When Rabelais's hero Pantagruel journeys to the "Oracle of The Div(in)e Bottle", he learns the lesson of life in one simple word: "Trinch!", Drink! Enjoy the simple life, learn wisdom and knowledge, as a free human. Beyond puns, irony, and satire, Gargantua's prologue-metaphor instructs the reader to "break the bone and suck out the substance-full marrow" ("la substantifique moëlle"), the core of wisdom.

Modern movements

The year 1600 is considered a landmark in the era of modern freethought. It was the year of the execution in Italy of Giordano Bruno, a former Dominican Monk, by the Inquisition.[17][18][19]

England

The term free-thinker emerged towards the end of the 17th century in England to describe those who stood in opposition to the institution of the Church, and the literal belief in the Bible. The beliefs of these individuals were centered on the concept that people could understand the world through consideration of nature. Such positions were formally documented for the first time in 1697 by William Molyneux in a widely publicized letter to John Locke, and more extensively in 1713, when Anthony Collins wrote his Discourse of Free-thinking, which gained substantial popularity. This essay attacks the clergy of all churches and it is a plea for deism.

The Freethinker magazine was first published in Britain in 1881.

France

In France, the concept first appeared in publication in 1765 when Denis Diderot, Jean le Rond d'Alembert, and Voltaire included an article on Liberté de penser in their Encyclopédie.[20] The European freethought concepts spread so widely that even places as remote as the Jotunheimen, in Norway, had well-known freethinkers such as Jo Gjende by the 19th century.[21]
François-Jean Lefebvre de la Barre (1745–1766) was a young French nobleman, famous for having been tortured and beheaded before his body was burnt on a pyre along with Voltaire's Philosophical Dictionary. La Barre is often said to have been executed for not saluting a Roman Catholic religious procession, but the elements of the case were far more complex.[22]

In France, Lefebvre de la Barre is widely regarded a symbol of the victims of Christian religious intolerance; La Barre along with Jean Calas and Pierre-Paul Sirven, was championed by Voltaire. A second replacement statue to de la Barre stands nearby the Basilica of the Sacred Heart of Jesus of Paris at the summit of the butte Montmartre (itself named from the Temple of Mars), the highest point in Paris and an 18th arrondissement street nearby the Sacré-Cœur is also named after Lefebvre de la Barre.

Germany

In Germany, during the period 1815–1848 and before the March Revolution, the resistance of citizens against the dogma of the church increased. In 1844, under the influence of Johannes Ronge and Robert Blum, belief in the rights of man, tolerance among men, and humanism grew, and by 1859 they had established the Bund Freireligiöser Gemeinden Deutschlands (literally Union of Free Religious Communities of Germany), an association of persons who consider themselves to be religious without adhering to any established and institutionalized church or sacerdotal cult. This union still exists today, and is included as a member in the umbrella organization of free humanists. In 1881 in Frankfurt am Main, Ludwig Büchner established the Deutscher Freidenkerbund (German Freethinkers League) as the first German organization for atheists and agnostics. In 1892 the Freidenker-Gesellschaft and in 1906 the Deutscher Monistenbund were formed.[23]

Freethought organizations developed the "Jugendweihe" (literally Youth consecration), a secular "confirmation" ceremony, and atheist funeral rites.[23][24] The Union of Freethinkers for Cremation was founded in 1905, and the Central Union of German Proletariat Freethinker in 1908. The two groups merged in 1927, becoming the German Freethinking Association in 1930.[25]

More "bourgeois" organizations declined after World War I, and "proletarian" Freethought groups proliferated, becoming an organization of socialist parties.[23][26] European socialist freethought groups formed the International of Proletarian Freethinkers (IPF) in 1925.[27] Activists agitated for Germans to disaffiliate from their respective Church and for seculari-zation of elementary schools; between 1919–21 and 1930–32 more than 2.5 million Germans, for the most part supporters of the Social Democratic and Communist parties, gave up church membership.[28] Conflict developed between radical forces including the Soviet League of the Militant Godless and Social Democratic forces in Western Europe led by Theodor Hartwig and Max Sievers.[27] In 1930 the Soviet and allied delegations, following a walk-out, took over the IPF and excluded the former leaders.[27] Following Hitler's rise to power in 1933, most freethought organizations were banned, though some right-wing groups that worked with so-called Völkische Bünde (literally "ethnic" associations with nationalist, xenophobic and very often racist ideology) were tolerated by the Nazis until the mid-1930s.[23][26]

Belgium

The Université Libre de Bruxelles and the Vrije Universiteit Brussel, along with the two Circles of Free Inquiry (Dutch and French speaking), defend the freedom of critical thought, lay philosophy and ethics, while rejecting the argument of authority.

Netherlands

In the Netherlands, freethought has existed in organized form since the establishment of De Dageraad (now known as De Vrije Gedachte) in 1856. Among its most notable subscribing 19th century individuals were Johannes van Vloten, Multatuli, Adriaan Gerhard and Domela Nieuwenhuis.

In 2009, Frans van Dongen established the Atheist-Secular Party, which takes a considerably restrictive view of religion and public religious expressions.

Since the 19th century, Freethought in the Netherlands has become more well known as a political phenomenon through at least three currents: liberal freethinking, conservative freethinking, and classical freethinking. In other words, parties which identify as freethinking tend to favor non-doctrinal, rational approaches to their preferred ideologies, and arose as secular alternatives to both clerically aligned parties as well as labor-aligned parties. Common themes among freethinking political parties are "freedom", "liberty", and "individualism".

United States

The Free Thought movement first organized itself in the United States as the "Free Press Association" in 1827 in defense of George Houston, publisher of The Correspondent, an early journal of Biblical criticism in an era when blasphemy convictions were still possible. Houston had helped found an Owenite community at Haverstraw, New York in 1826–27. The short-lived Correspondent was superseded by the Free Enquirer, the official organ of Robert Owen's New Harmony community in Indiana, edited by Robert Dale Owen and by Fanny Wright between 1828 and 1832 in New York. During this time Robert Dale Owen sought to introduce the philosophic skepticism of the Free Thought movement into the Workingmen's Party in New York City. The Free Enquirer's annual civic celebrations of Paine's birthday after 1825 finally coalesced in 1836 in the first national Free Thinkers organization, the "United States Moral and Philosophical Society for the General Diffusion of Useful Knowledge". It was founded on August 1, 1836, at a national convention at the Lyceum in Saratoga Springs with Isaac S. Smith of Buffalo, New York, as president. Smith was also the 1836 Equal Rights Party's candidate for Governor of New York and had also been the Workingmen's Party candidate for Lt. Governor of New York in 1830. The Moral and Philosophical Society published The Beacon, edited by Gilbert Vale.[29]


Driven by the revolutions of 1848 in the German states, the 19th century saw an immigration of German freethinkers and anti-clericalists to the United States (see Forty-Eighters). In the United States, they hoped to be able to live by their principles, without interference from government and church authorities.[31]

Many Freethinkers settled in German immigrant strongholds, including St. Louis, Indianapolis, Wisconsin, and Texas, where they founded the town of Comfort, Texas, as well as others.[31]

These groups of German Freethinkers referred to their organizations as Freie Gemeinden, or "free congregations".[31] The first Freie Gemeinde was established in St. Louis in 1850.[32] Others followed in Pennsylvania, California, Washington, D.C., New York, Illinois, Wisconsin, Texas, and other states.[31][32]

Freethinkers tended to be liberal, espousing ideals such as racial, social, and sexual equality, and the abolition of slavery.[31]

The "Golden Age of Freethought" in the US came in the late 1800s. The dominant organization was the National Liberal League which formed in 1876 in Philadelphia. This group re-formed itself in 1885 as the American Secular Union under the leadership of the eminent agnostic orator Robert G. Ingersoll. Following Ingersoll's death in 1899 the organization declined, in part due to lack of effective leadership.[33]

Freethought in the United States declined in the early twentieth century. Its anti-religious views alienated would-be sympathizers.[citation needed] The movement also lacked cohesive goals or beliefs. By the early twentieth century, most Freethought congregations had disbanded or joined other mainstream churches. The longest continuously operating Freethought congregation in America is the Free Congregation of Sauk County, Wisconsin, which was founded in 1852 and is still active as of 2016. It affiliated with the American Unitarian Association (now the Unitarian Universalist Association) in 1955.[34] D. M. Bennett was the founder and publisher of The Truth Seeker in 1873, a radical freethought and reform American periodical.

German Freethinker settlements were located in:

Canada

In 1873 a handful of secularists founded the earliest known secular organization in English Canada, the Toronto Freethought Association. Reorganized in 1877 and again in 1881, when it was renamed the Toronto Secular Society, the group formed the nucleus of the Canadian Secular Union, established in 1884 to bring together freethinkers from across the country.

A significant number of the early members appear to have come from the educated labour "aristocracy", including Alfred F. Jury, J. Ick Evans and J. I. Livingstone, all of whom were leading labour activists and secularists. The second president of the Toronto association, T. Phillips Thompson, became a central figure in the city's labour and social-reform movements during the 1880s and 1890s and arguably Canada's foremost late nineteenth-century labour intellectual. By the early 1880s scattered freethought organizations operated throughout southern Ontario and parts of Quebec, eliciting both urban and rural support.

The principal organ of the freethought movement in Canada was Secular Thought (Toronto, 1887–1911). Founded and edited during its first several years by English freethinker Charles Watts (1835–1906), it came under the editorship of Toronto printer and publisher James Spencer Ellis in 1891 when Watts returned to England.

In 1968 the Humanist Association of Canada (HAC) formed to serve as an umbrella group for humanists, atheists, and freethinkers, and to champion social justice issues and oppose religious influence on public policy—most notably in the fight to make access to abortion free and legal in Canada. HAC, also known as Humanist Canada, operates as an active voice for humanism in Canada[citation needed] and supports the activities of groups who wish to raise awareness about secular issues.

The Canadian Secular Alliance is an active community.[citation needed]

Anarchism

In the United States, "freethought was a basically anti-christian, anti-clerical movement, whose purpose was to make the individual politically and spiritually free to decide for himself on religious matters. A number of contributors to Liberty were prominent figures in both freethought and anarchism. The individualist anarchist George MacDonald was a co-editor of Freethought and, for a time, The Truth Seeker. E.C. Walker was co-editor of the freethought/free love journal Lucifer, the Light-Bearer."[37] "Many of the anarchists were ardent freethinkers; reprints from freethought papers such as Lucifer, the Light-Bearer, Freethought and The Truth Seeker appeared in Liberty...The church was viewed as a common ally of the state and as a repressive force in and of itself."[37]

In Europe, a similar development occurred in French and Spanish individualist anarchist circles. "Anticlericalism, just as in the rest of the libertarian movement, in another of the frequent elements which will gain relevance related to the measure in which the (French) Republic begins to have conflicts with the church...Anti-clerical discourse, frequently called for by the French individualist André Lorulot, will have its impacts in Estudios (a Spanish individualist anarchist publication). There will be an attack on institutionalized religion for the responsibility that it had in the past on negative developments, for its irrationality which makes it a counterpoint of philosophical and scientific progress. There will be a criticism of proselitism and ideological manipulation which happens on both believers and agnostics".[38] These tendencies will continue in French individualist anarchism in the work and activism of Charles-Auguste Bontemps and others. In the Spanish individualist anarchist magazines Ética and Iniciales "there is a strong interest in publishing scientific news, usually linked to a certain atheist and anti-theist obsession, philosophy which will also work for pointing out the incompatibility between science and religion, faith, and reason. In this way there will be a lot of talk on Darwin´s theories or on the negation of the existence of the soul".[39]

In 1901, Catalan anarchist and freethinker Francesc Ferrer i Guàrdia established "modern" or progressive schools in Barcelona in defiance of an educational system controlled by the Catholic Church.[40] The schools' stated goal was to "educate the working class in a rational, secular and non-coercive setting". Fiercely anti-clerical, Ferrer believed in "freedom in education", education free from the authority of church and state.[41] Ferrer's ideas, generally, formed the inspiration for a series of Modern Schools in the United States,[40] Cuba, South America and London. The first of these was started in New York City in 1911. It also inspired the Italian newspaper Università popolare, founded in 1901.

Ray Kurzweil reveals plans for ‘linguistically fluent’ Google software

Ray Kuzweil, a director of engineering at Google, reveals plans for a future version of Google’s “Smart Reply” machine-learning email software (and more) in a Wired article by Tom Simonite published Wednesday (Aug. 2, 2017).

Running on mobile Gmail and Google Inbox, Smart Reply suggests up to three replies to an email message, saving typing time or giving you ideas for a better reply.

Smarter autocomplete

Kurzweil’s team is now “experimenting with empowering Smart Reply to elaborate on its initial terse suggestions,” Simonite says.

“Tapping a Continue button [in response to an email] might cause ‘Sure I’d love to come to your party!’ to expand to include, for example, ‘Can I bring something?’ He likes the idea of having AI pitch in anytime you’re typing, a bit like an omnipresent, smarter version of Google’s search autocomplete. ‘You could have similar technology to help you compose documents or emails by giving you suggestions of how to complete your sentence,’ Kurzweil says.”

As Simonite notes, Kurzweil’s software is based on his hierarchical theory of intelligence, articulated in Kurzweil’s latest book, How to Create a Mind and in more detail in an arXiv paper by Kurzweil and key members of his team, published in May.

“Kurzweil’s work outlines a path to create a simulation of the human neocortex (the outer layer of the brain where we do much of our thinking) by building a hierarchy of similarly structured components that encode increasingly abstract ideas as sequences,” according to the paper. “Kurzweil provides evidence that the neocortex is a self-organizing hierarchy of modules, each of which can learn, remember, recognize and/or generate a sequence, in which each sequence consists of a sequential pattern from lower-level modules.”

The paper further explains that Smart Reply previously used a “long short-term memory” (LSTM) network*, “which are much slower than feed-forward networks [used in the new software] for training and inference” because with LSTM, it takes more computation to handle longer sequences of words.

Kurzweil’s team was able to produce email responses of similar quality to LSTM, but using fewer computational resources by training hierarchically connected layers of simulated neurons on clustered numerical representations of text. Essentially, the approach propagates information through a sequence of ever more complex pattern recognizers until the final patterns are matched to optimal responses.

Kona: linguistically fluent software

But underlying Smart Reply is “a system for understanding the meaning of language, according to Kurzweil,” Simonite reports.

“Codenamed Kona, the effort is aiming for nothing less than creating software as linguistically fluent as you or me. ‘I would not say it’s at human levels, but I think we’ll get there,’ Kurzweil says. More applications of Kona are in the works and will surface in future Google products, he promises.”

* The previous sequence-to-sequence (Seq2Seq) framework [described in this paper] uses “recurrent neural networks (RNNs), typically long short-term memory (LSTM) networks, to encode sequences of word embeddings into representations that depend on the order, and uses a decoder RNN to generate output sequences word by word. …While Seq2Seq models provide a generalized solution, it is not obvious that they are maximally efficient, and training these systems can be slow and complicated.”
