A sophist (Greek: σοφιστής, sophistes) was a specific kind of teacher in ancient Greece, in the fifth and fourth centuries BC. Many sophists specialized in using the tools of philosophy and rhetoric, though other sophists taught subjects such as music, athletics and mathematics. In general, they claimed to teach arete ("excellence" or "virtue", applied to various subject areas), predominantly to young statesmen and nobility.
The term sophist comes from the Greek term σοφιστής (sophistēs), which is derived from σοφός (sophós) meaning "wise man", σοφία (sophia) meaning "wisdom" and σοφίζω (Sophizo) meaning "I am wise". It stands for a "wise maker", that is, one who makes pupils wise.

Etymology
The Greek  σοφός (sophos), related to the noun σοφία (sophia), had the meaning "skilled" or "wise" since the time of the poet Homer
 and originally was used to describe anyone with expertise in a specific
 domain of knowledge or craft. For example, a charioteer, a sculptor, or
 a warrior could be described as sophoi in their occupations. 
Gradually, the word also came to denote general wisdom and especially 
wisdom about human affairs, for example, in politics, ethics, or 
household management. This was the meaning ascribed to the Greek Seven Sages of 7th and 6th century BC (such as Solon and Thales), and it was the meaning that appears in the histories of Herodotus. 
From the word σοφός (sophos) is derived the verb σοφίζω (sophizo),
 which means "to instruct or make learned", and in the passive voice 
means "to become or be wise", or "to be clever or skilled in a thing". 
From this verb is derived the noun σοφιστής (sophistes), which originally meant "a master of one's craft" but later came to mean "a prudent man" or "wise man". The word for "sophist" in various languages comes from sophistes.
The word "sophist" could be combined with other Greek words to form compounds. Examples include meteorosophist, which roughly translates to "expert in celestial phenomena"; gymnosophist (or "naked sophist", a word used to refer to Indian philosophers, deipnosophist or "dinner sophist" (as in the title of Athenaeus's Deipnosophistae), and iatrosophist, a type of physician in the later Roman period.
History
Few 
writings from and about the first sophists survive. The early sophists 
charged money in exchange for education and providing wisdom, and so 
were typically employed by wealthy people. This practice resulted in the
 condemnations made by Socrates through Plato in his dialogues, as well as by Xenophon in his Memorabilia and, somewhat controversially, by Aristotle. As a paid tutor to Alexander the Great, Aristotle could be accused of being a sophist. Aristotle did not actually accept payment from Philip, Alexander's father, but requested that Philip reconstruct Aristotle's home town of Stageira as payment, which Philip had destroyed in a previous campaign, terms which Philip accepted. James A. Herrick wrote: "In De Oratore, Cicero blames Plato for separating wisdom and eloquence in the philosopher's famous attack on the sophists in Gorgias." Through works such as these, sophists were portrayed as "specious" or "deceptive", hence the modern meaning of the term.
The classical tradition of rhetoric and composition refers more to philosophers such as Aristotle, Cicero, and Quintilian than to the sophists. Owing largely to the influence of Plato and Aristotle, philosophy
 came to be regarded as distinct from sophistry, the latter being 
regarded as specious and rhetorical, a practical discipline. Thus, by 
the time of the Roman Empire, a sophist was simply a teacher of rhetoric and a popular public speaker. For instance, Libanius, Himerius, Aelius Aristides, and Fronto were sophists in this sense.
 However, despite the opposition from philosophers Socrates, Plato, and 
Aristotle, it is clear that sophists had a vast influence on a number of
 spheres, including the growth of knowledge and on ethical political 
theory.  Their teachings had a huge influence on thought in the fifth 
century BCE.
 The sophists focused on the rational examination of human affairs and 
the betterment and success of human life.  They argued that gods could 
not be the explanation of human action.
5th century BC
In the second half of the 5th century BC, particularly in Athens,
 "sophist" came to denote a class of mostly itinerant intellectuals who 
taught courses in various subjects, speculated about the nature of 
language and culture, and employed rhetoric
 to achieve their purposes, generally to persuade or convince others. 
"Sophists did, however, have one important thing in common: whatever 
else they did or did not claim to know, they characteristically had a 
great understanding of what words would entertain or impress or persuade
 an audience."
 Sophists went to Athens to teach because the city was flourishing at 
the time. It was good employment for those good at debate, which was a 
specialty of the first sophists, and they received the fame and fortune 
they were seeking. Protagoras is generally regarded as the first of these professional sophists. Others include Gorgias, Prodicus, Hippias, Thrasymachus, Lycophron, Callicles, Antiphon, and Cratylus.
 A few sophists claimed that they could find the answers to all 
questions.  Most of these sophists are known today primarily through the
 writings of their opponents (particularly Plato and Aristotle), which makes it difficult to assemble an unbiased view of their practices and teachings. In some cases, such as Gorgias,
  original rhetorical works are extant, allowing the author to be judged
 on his own terms, but in most cases knowledge about what individual 
sophists wrote or said comes from fragmentary quotations that lack 
context and are usually hostile.
Sophists could be described both as teachers and philosophers,
 having traveled about in Greece teaching their students various life 
skills, particularly rhetoric and public speaking. These were useful 
qualities of the time, during which persuasive ability had a large 
influence on one's political power and economic wealth. Athens became 
the center of the sophists' activity, due to the city's freedom of 
speech for non-slave citizens and its wealth of resources. The sophists 
as a group had no set teachings, and they lectured on subjects that were
 as diverse as semantics and rhetoric, to ontology, and epistemology. Most sophists claimed to teach arête
 (“excellence” or “virtue”) in the management and administration of not 
only one’s affairs, but the city’s as well. Before the fifth century BC,
 it was believed that aristocratic birth qualified a person for arête 
and politics.  However, Protagoras, who is regarded as the first 
sophist, argued that arête was the result of training rather than birth.
1st century AD
From the late 1st century CE the Second Sophistic,
 a philosophical and rhetorical movement, was the chief expression of 
intellectual life. The term "Second Sophistic" comes from Philostratos,
 who rejecting the term "New Sophistic" traced the beginnings of the 
movement to the orator Aeschines in the 4th century BC. But its earliest
 representative was really Nicetas of Smyrna,
 in the late 1st century AD. Unlike the original Sophistic movement of 
the 5th century BC, the Second Sophistic was little concerned with politics. But it was, to a large degree, to meet the everyday needs and respond to the practical problems of Greco-Roman society. It came to dominate higher education and left its mark on many forms of literature. Lucian, himself a writer of the Second Sophistic, even calls Jesus "that crucified sophist". This article, however, only discusses the Sophists of Classical Greece.
Major figures
Most
 of what is known about sophists comes from commentaries from others. In
 some cases, such as Gorgias, some of his works survive, allowing the 
author to be judged on his own terms. In one case, the Dissoi logoi,
 an important sophist text survived but knowledge of its author has been
 lost. However, most knowledge of sophist thought comes from fragmentary
 quotations that lack context. Many of these quotations come from Aristotle, who seems to have held the sophists in slight regard.
Protagoras
Protagoras was one of the best known and most successful sophists of his era; however, some later philosophers, such as Sextus Empiricus
 treat him as a founder of a philosophy rather than as a sophist. 
Protagoras taught his students the necessary skills and knowledge for a 
successful life, particularly in politics. He trained his pupils to 
argue from both points of view because he believed that truth could not 
be limited to just one side of the argument. Protagoras wrote about a 
variety of subjects and advanced several philosophical ideas, 
particularly in epistemology.
 Some fragments of his works have survived.  He is the author of the 
famous saying, "Man is the measure of all things," which is the opening 
sentence of a work called Truth.
Gorgias
Gorgias
 was a well-known sophist whose writings showcased his ability to make 
counter-intuitive and unpopular positions appear stronger. Gorgias 
authored a lost work known as On the Non-Existent, which argues that nothing exists. In it, he attempts to persuade his readers that thought and existence are different. He also wrote Encomium of Helen in which he presents all of the possible reasons for which Helen could be blamed for causing the Trojan War and refutes each one of them.
Criticism
Many
 sophists taught their skills for a price. Due to the importance of such
 skills in the litigious social life of Athens, practitioners often 
commanded very high fees. The sophists' practice of questioning the 
existence and roles of traditional deities and investigating into the 
nature of the heavens and the earth prompted a popular reaction against 
them. The attacks of some of their followers against Socrates prompted a vigorous condemnation from his followers, including Plato and Xenophon, as there was a popular view of Socrates as a sophist. For example, in the comic playwright The Clouds, Aristophanes criticizes the sophists as hairsplitting wordsmiths, and makes Socrates their representative.
 Their attitude, coupled with the wealth garnered by many of the 
sophists, eventually led to popular resentment against sophist 
practitioners and the ideas and writings associated with sophism.
Plato
As only small portions of the sophists’ writings have survived they are mainly known through the works of Plato.
 Plato's dialogs present his generally hostile views on the sophists’ 
thought, due to which he is largely responsible for the modern view of 
the sophist as an avaricious instructor who teaches deception.  Plato 
depicts Socrates as refuting some sophists in several of his dialogues, 
depicting sophists in an unflattering light. It is unclear how accurate 
or fair Plato's representation of them may be; however, Protagoras and 
Prodicus are portrayed in a largely positive light in.
Aristophanes
The comic playwright Aristophanes,
 a contemporary of the sophists, criticized the sophists as 
hairsplitting wordsmiths.  Aristophanes, however, made no distinction 
between sophists and philosophers, and showed either of them as willing 
to argue any position for the right fee. In Aristophanes's comedic play The Clouds,
 Strepsiades seeks the help of Socrates (a parody of the actual 
philosopher) in an effort to avoid paying his debts. In the play, 
Socrates promises to teach Strepsiades' son to argue his way out of 
paying his debts.
Socrates
An ongoing debate is centered on the difference between the sophists, who charged for their services, and Socrates, who did not. Instead of giving instruction Socrates professed a self-effacing and questioning posture, exemplified by what is known as the Socratic method, although Diogenes Laërtius wrote that Protagoras—a sophist—invented this method.)
 Socrates' attitude towards the sophists was by not entirely 
oppositional. In one dialogue Socrates even stated that the sophists 
were better educators than he was, which he validated by sending one of his students to study under a sophist. W. K. C. Guthrie classified Socrates as a sophist in his History of Greek Philosophy.
Before Plato, the word "sophist" could be used as either a respectful or contemptuous title. It was in Plato’s dialogue, Sophist,
 that the first record of an attempt to answer the question “what is a 
sophist?” is made. Plato described sophists as paid hunters after the 
young and wealthy, as merchants of knowledge, as athletes in a contest 
of words, and purgers of souls. From Plato's assessment of sophists it 
could be concluded that sophists do not offer true knowledge, but only 
an opinion of things. Plato describes them as shadows of the true, 
saying, "[...] the art of contradiction making, descended from an 
insincere kind of conceited mimicry, of the semblance-making breed, 
derived from image making, distinguished as portion, not divine but 
human, of production, that presents, a shadow play of words—such are the
 blood and the lineage which can, with perfect truth, be assigned to the
 authentic sophist". Plato sought to distinguish sophists from 
philosophers, arguing that a sophist was a person who made his living 
through deception, whereas a philosopher was a lover of wisdom who 
sought the truth. To give the philosophers greater credence, Plato gave 
the sophists a negative connotation.
Plato
 depicts Socrates as refuting  sophists in several dialogues.  These 
texts often depict the sophists in an unflattering light, and it is 
unclear how accurate or fair Plato's representation of them may be; 
however, Protagoras and Prodicus are portrayed in a largely positive 
light in Protagoras (dialogue). Protagoras argued that "man is the measure of all things," meaning man decides for himself what he is going to believe.
 The works of Plato and Aristotle have had much influence on the modern 
view of the "sophist" as a greedy instructor who uses rhetorical 
sleight-of-hand and ambiguities of language in order to deceive, or to 
support fallacious reasoning. In this view, the sophist is not concerned
 with truth and justice, but instead seeks power.
Some scholars, such as Ugo Zilioli argue that the sophists held a relativistic view on cognition and knowledge. However, this may involve the Greek word "doxa", which means "culturally shared belief" rather than "individual opinion." The sophists' philosophy contains criticisms of religion, law, and ethics. Although many sophists were apparently as religious as their contemporaries, some held atheistic or agnostic views (for example, Protagoras and Diagoras of Melos).
Influence
Democracy
The
 sophists' rhetorical techniques were useful for any young nobleman 
looking for public office. The societal roles the sophists filled had 
important ramifications for the Athenian political system. The 
historical context provides evidence for their considerable influence, 
as Athens became more and more democratic during the period in which the
 sophists were most active.
Even though Athens was already a flourishing democracy before 
their arrival, the cultural and psychological contributions of the 
sophists played an important role in the growth of Athenian democracy. 
Sophists contributed to the new democracy in part by espousing expertise
 in public deliberation, the foundation of decision-making, which 
allowed—and perhaps required—a tolerance of the beliefs of others. This 
liberal attitude would naturally have made its way into the Athenian 
assembly as sophists began acquiring increasingly high-powered clients.
 Continuous rhetorical training gave the citizens of Athens "the ability
 to create accounts of communal possibilities through persuasive 
speech".
 This was important for the democracy, as it gave disparate and 
sometimes superficially unattractive views a chance to be heard in the 
Athenian assembly.
In addition, sophists had a great impact on the early development of law,
 as the sophists were the first lawyers in the world. Their status as 
lawyers was a result of their highly developed skills in argument.
Education
Athens
The
 sophists were the first formal teachers of the art of speaking and 
writing in the Western world. Their influence on education in general, 
and medical education in particular, has been described by Seamus Mac 
Suibhne. The sophists "offer quite a different epistemic field from that mapped by Aristotle", according to scholar Susan Jarratt, writer of Rereading the Sophists: Classical Rhetoric Refigured.
For the sophists, the science of eloquence became a method to 
earn money. In order to teach their students the art of persuasion and 
demonstrate their thoughts, they focused on two techniques: dialectics and rhetoric.
 The sophists taught their students two main techniques: the usage of 
sophisms and controversies. These means distinguished the speeches of 
the sophists from the other speakers. Controversies were important to 
the Sophists because they believed that a good rhetorician should be 
able to defend both his own opinion and the exact opposite one. In this 
way, was developed the ability to find clear, convincing arguments for 
any thesis. For the sophists, the primary purpose was to win the dispute
 in order to prove their excellence in word usage. They were convinced 
that there was no verity, but there were different opinions, equal in 
importance, and the "verity" was the only one that would be more 
convincingly demonstrated by the rhetorician.
Sophists were not limited in their speeches only to topics in 
which they were aware. For them, there were no topics they could not 
dispute, because their skill reached such a level that they were able to
 talk about completely unknown things to them and still impress upon 
listeners and the opponent. The main purpose was to pick an approach to 
the audience, to please it and to adapt the speech to it. Unlike Plato's
 approach, the Sophist rhetoricians did not focus on identifying the 
truth, but the most important thing for them was to prove their case.
The first sophist whose speeches are a perfect example of a 
sophisticated approach is Gorgias. One of his most famous speeches is 
the "Praise of Helen", which has made a significant contribution to 
rhetorical art. In this speech, Gorgias aims to make something almost 
impossible - to justify Helen, about whom the people have already had a 
negative opinion. By methods of double oppositions, stringing of 
repetitive positive qualities and insightful consistent arguments, 
Gorgias Leontynets gradually purifies the poor reputation of a woman. 
Later, Aristotle
 described the means used in Gorgias' speech as "Gorgias figures". All 
of these figures create the most accessible to the audience, varying 
depending on the type of speech and audience.
Rome
During the Second Sophistic,
 the Greek discipline of rhetoric heavily influenced Roman education. 
During this time Latin rhetorical studies were banned for the precedent 
of Greek rhetorical studies. In addition, Greek history was preferred 
for educating the Roman elites above that of their native Roman history.
Many rhetoricians during this period were instructed under 
specialists in Greek rhetorical studies as part of their standard 
education. Cicero,
 a prominent rhetorician during this period in Roman history, is one 
such example of the influence of the Second Sophistic on Roman 
education. His early life coincided with the suppression of Latin 
rhetoric in Roman education under the edicts of Crassus
 and Domitius. Cicero was instructed in Greek rhetoric throughout his 
youth, as well as in other subjects of the Roman rubric under Archias. 
Cicero benefited in his early education from favorable ties to Crassus.
In his writings, Cicero is said to have shown a "synthesis that 
he achieved between Greek and Roman culture" summed up in his work De Oratore. Despite
 his oratorical skill, Cicero pressed for a more liberal education in 
Roman instruction which focused more in the broad sciences including 
Roman history. He entitled this set of sciences as politior humanitas
 (2.72). Regardless of his efforts toward this end, Greek history was 
still preferred by the majority of aristocratic Romans during this time.
Modern usage
In modern usage, sophism, sophist and sophistry are used disparagingly. A sophism is a fallacious argument, especially one used deliberately to deceive. A sophist is a person who reasons with clever but fallacious and deceptive arguments.
