Evolutionarily stable strategy

From Wikipedia, the free encyclopedia
 
Evolutionarily stable strategy

An evolutionarily stable strategy (ESS) is a strategy (or set of strategies) that is impermeable when adopted by a population in adaptation to a specific environment, that is to say it cannot be displaced by an alternative strategy (or set of strategies) which may be novel or initially rare. Introduced by John Maynard Smith and George R. Price in 1972/3, it is an important concept in behavioural ecology, evolutionary psychology, mathematical game theory and economics, with applications in other fields such as anthropology, philosophy and political science.

In game-theoretical terms, an ESS is an equilibrium refinement of the Nash equilibrium, being a Nash equilibrium that is also "evolutionarily stable." Thus, once fixed in a population, natural selection alone is sufficient to prevent alternative (mutant) strategies from replacing it (although this does not preclude the possibility that a better strategy, or set of strategies, will emerge in response to selective pressures resulting from environmental change).

History

Evolutionarily stable strategies were defined and introduced by John Maynard Smith and George R. Price in a 1973 Nature paper. Such was the time taken in peer-reviewing the paper for Nature that this was preceded by a 1972 essay by Maynard Smith in a book of essays titled On Evolution. The 1972 essay is sometimes cited instead of the 1973 paper, but university libraries are much more likely to have copies of Nature. Papers in Nature are usually short; in 1974, Maynard Smith published a longer paper in the Journal of Theoretical Biology. Maynard Smith explains further in his 1982 book Evolution and the Theory of Games. Sometimes these are cited instead. In fact, the ESS has become so central to game theory that often no citation is given, as the reader is assumed to be familiar with it.

Maynard Smith mathematically formalised a verbal argument made by Price, which he read while peer-reviewing Price's paper. When Maynard Smith realized that the somewhat disorganised Price was not ready to revise his article for publication, he offered to add Price as co-author.

Maynard Smith on p.174 of the Postscript in his, 1982 work Evolution and the Theory of Games argues that the concept of an ESS is itself polyphyletic (i.e. derives from more than one common evolutionary ancestral group or ancestor). In this he not only mentions Price but also list various other sources for the concept. These include the following:

  • variable behaviour being explained in terms of frequency-dependent selection which he sources to Madhav Gadgil's 1972 work on Male dimorphism as a consequence of sexual selection, and Geoff Parker's 1970 work on The reproductive behaviour and the nature of sexual selection in Scatophaga stercoraria.
  • equilibrium by equalising the payoffs for producing sons and daughters, which he sources to Richard F. Shaw and James Dawson Mohler (1953)
  • the analysis of animal dispersal, which uses the observation that "fitness" should be equal at an "equilibrium" if we are to achieve an ideal free distribution is sourced to Stephen D. Fretwell and Henry L Lucas (1970).
  • the idea that reciprocal altruism can be understood for the same two opponents in a repeated game as an ESS being sourced to Robert Trivers (1971).

But the concept proper was derived from R. H. MacArthur and W. D. Hamilton's work on sex ratios, derived from Fisher's principle, especially Hamilton's (1967) concept of an unbeatable strategy. Maynard Smith was jointly awarded the 1999 Crafoord Prize for his development of the concept of evolutionarily stable strategies and the application of game theory to the evolution of behaviour.

Uses of ESS:

Motivation

The Nash equilibrium is the traditional solution concept in game theory. It depends on the cognitive abilities of the players. It is assumed that players are aware of the structure of the game and consciously try to predict the moves of their opponents and to maximize their own payoffs. In addition, it is presumed that all the players know this (see common knowledge). These assumptions are then used to explain why players choose Nash equilibrium strategies.

Evolutionarily stable strategies are motivated entirely differently. Here, it is presumed that the players' strategies are biologically encoded and heritable. Individuals have no control over their strategy and need not be aware of the game. They reproduce and are subject to the forces of natural selection, with the payoffs of the game representing reproductive success (biological fitness). It is imagined that alternative strategies of the game occasionally occur, via a process like mutation. To be an ESS, a strategy must be resistant to these alternatives.

Given the radically different motivating assumptions, it may come as a surprise that ESSes and Nash equilibria often coincide. In fact, every ESS corresponds to a Nash equilibrium, but some Nash equilibria are not ESSes.

Nash equilibrium

An ESS is a refined or modified form of a Nash equilibrium. (See the next section for examples which contrast the two.) In a Nash equilibrium, if all players adopt their respective parts, no player can benefit by switching to any alternative strategy. In a two player game, it is a strategy pair. Let E(S,T) represent the payoff for playing strategy S against strategy T. The strategy pair (S, S) is a Nash equilibrium in a two player game if and only if for both players, for any strategy T:

E(S,S) ≥ E(T,S)

In this definition, a strategy TS can be a neutral alternative to S (scoring equally well, but not better). A Nash equilibrium is presumed to be stable even if T scores equally, on the assumption that there is no long-term incentive for players to adopt T instead of S. This fact represents the point of departure of the ESS.

Maynard Smith and Price specify two conditions for a strategy S to be an ESS. For all TS, either

  1. E(S,S) > E(T,S), or
  2. E(S,S) = E(T,S) and E(S,T) > E(T,T)

The first condition is sometimes called a strict Nash equilibrium. The second is sometimes called "Maynard Smith's second condition". The second condition means that although strategy T is neutral with respect to the payoff against strategy S, the population of players who continue to play strategy S has an advantage when playing against T.

There is also an alternative, stronger definition of ESS, due to Thomas. This places a different emphasis on the role of the Nash equilibrium concept in the ESS concept. Following the terminology given in the first definition above, this definition requires that for all TS

  1. E(S,S) ≥ E(T,S), and
  2. E(S,T) > E(T,T)

In this formulation, the first condition specifies that the strategy is a Nash equilibrium, and the second specifies that Maynard Smith's second condition is met. Note that the two definitions are not precisely equivalent: for example, each pure strategy in the coordination game below is an ESS by the first definition but not the second.

In words, this definition looks like this: The payoff of the first player when both players play strategy S is higher than (or equal to) the payoff of the first player when he changes to another strategy T and the second player keeps his strategy S and the payoff of the first player when only his opponent changes his strategy to T is higher than his payoff in case that both of players change their strategies to T.

This formulation more clearly highlights the role of the Nash equilibrium condition in the ESS. It also allows for a natural definition of related concepts such as a weak ESS or an evolutionarily stable set.

Examples of differences between Nash equilibria and ESSes


Cooperate Defect
Cooperate 3, 3 1, 4
Defect 4, 1 2, 2
Prisoner's Dilemma

A B
A 2, 2 1, 2
B 2, 1 2, 2
Harm thy neighbor

In most simple games, the ESSes and Nash equilibria coincide perfectly. For instance, in the prisoner's dilemma there is only one Nash equilibrium, and its strategy (Defect) is also an ESS.

Some games may have Nash equilibria that are not ESSes. For example, in harm thy neighbor (whose payoff matrix is shown here) both (A, A) and (B, B) are Nash equilibria, since players cannot do better by switching away from either. However, only B is an ESS (and a strong Nash). A is not an ESS, so B can neutrally invade a population of A strategists and predominate, because B scores higher against B than A does against B. This dynamic is captured by Maynard Smith's second condition, since E(A, A) = E(B, A), but it is not the case that E(A,B) > E(B,B).


C D
C 2, 2 1, 2
D 2, 1 0, 0
Harm everyone

Swerve Stay
Swerve 0,0 −1,+1
Stay +1,−1 −20,−20
Chicken

Nash equilibria with equally scoring alternatives can be ESSes. For example, in the game Harm everyone, C is an ESS because it satisfies Maynard Smith's second condition. D strategists may temporarily invade a population of C strategists by scoring equally well against C, but they pay a price when they begin to play against each other; C scores better against D than does D. So here although E(C, C) = E(D, C), it is also the case that E(C,D) > E(D,D). As a result, C is an ESS.

Even if a game has pure strategy Nash equilibria, it might be that none of those pure strategies are ESS. Consider the Game of chicken. There are two pure strategy Nash equilibria in this game (Swerve, Stay) and (Stay, Swerve). However, in the absence of an uncorrelated asymmetry, neither Swerve nor Stay are ESSes. There is a third Nash equilibrium, a mixed strategy which is an ESS for this game (see Hawk-dove game and Best response for explanation).

This last example points to an important difference between Nash equilibria and ESS. Nash equilibria are defined on strategy sets (a specification of a strategy for each player), while ESS are defined in terms of strategies themselves. The equilibria defined by ESS must always be symmetric, and thus have fewer equilibrium points.

Vs. evolutionarily stable state

In population biology, the two concepts of an evolutionarily stable strategy (ESS) and an evolutionarily stable state are closely linked but describe different situations.

In an evolutionarily stable strategy, if all the members of a population adopt it, no mutant strategy can invade. Once virtually all members of the population use this strategy, there is no 'rational' alternative. ESS is part of classical game theory.

In an evolutionarily stable state, a population's genetic composition is restored by selection after a disturbance, if the disturbance is not too large. An evolutionarily stable state is a dynamic property of a population that returns to using a strategy, or mix of strategies, if it is perturbed from that initial state. It is part of population genetics, dynamical system, or evolutionary game theory. This is now called convergent stability.

B. Thomas (1984) applies the term ESS to an individual strategy which may be mixed, and evolutionarily stable population state to a population mixture of pure strategies which may be formally equivalent to the mixed ESS.

Whether a population is evolutionarily stable does not relate to its genetic diversity: it can be genetically monomorphic or polymorphic.

Stochastic ESS

In the classic definition of an ESS, no mutant strategy can invade. In finite populations, any mutant could in principle invade, albeit at low probability, implying that no ESS can exist. In an infinite population, an ESS can instead be defined as a strategy which, should it become invaded by a new mutant strategy with probability p, would be able to counterinvade from a single starting individual with probability >p, as illustrated by the evolution of bet-hedging.

Prisoner's dilemma


Cooperate Defect
Cooperate 3, 3 1, 4
Defect 4, 1 2, 2
Prisoner's Dilemma

A common model of altruism and social cooperation is the Prisoner's dilemma. Here a group of players would collectively be better off if they could play Cooperate, but since Defect fares better each individual player has an incentive to play Defect. One solution to this problem is to introduce the possibility of retaliation by having individuals play the game repeatedly against the same player. In the so-called iterated Prisoner's dilemma, the same two individuals play the prisoner's dilemma over and over. While the Prisoner's dilemma has only two strategies (Cooperate and Defect), the iterated Prisoner's dilemma has a huge number of possible strategies. Since an individual can have different contingency plan for each history and the game may be repeated an indefinite number of times, there may in fact be an infinite number of such contingency plans.

Three simple contingency plans which have received substantial attention are Always Defect, Always Cooperate, and Tit for Tat. The first two strategies do the same thing regardless of the other player's actions, while the latter responds on the next round by doing what was done to it on the previous round—it responds to Cooperate with Cooperate and Defect with Defect.

If the entire population plays Tit-for-Tat and a mutant arises who plays Always Defect, Tit-for-Tat will outperform Always Defect. If the population of the mutant becomes too large — the percentage of the mutant will be kept small. Tit for Tat is therefore an ESS, with respect to only these two strategies. On the other hand, an island of Always Defect players will be stable against the invasion of a few Tit-for-Tat players, but not against a large number of them. If we introduce Always Cooperate, a population of Tit-for-Tat is no longer an ESS. Since a population of Tit-for-Tat players always cooperates, the strategy Always Cooperate behaves identically in this population. As a result, a mutant who plays Always Cooperate will not be eliminated. However, even though a population of Always Cooperate and Tit-for-Tat can coexist, if there is a small percentage of the population that is Always Defect, the selective pressure is against Always Cooperate, and in favour of Tit-for-Tat. This is due to the lower payoffs of cooperating than those of defecting in case the opponent defects.

This demonstrates the difficulties in applying the formal definition of an ESS to games with large strategy spaces, and has motivated some to consider alternatives.

Human behavior

The fields of sociobiology and evolutionary psychology attempt to explain animal and human behavior and social structures, largely in terms of evolutionarily stable strategies. Sociopathy (chronic antisocial or criminal behavior) may be a result of a combination of two such strategies.

Evolutionarily stable strategies were originally considered for biological evolution, but they can apply to other contexts. In fact, there are stable states for a large class of adaptive dynamics. As a result, they can be used to explain human behaviours that lack any genetic influences.

Demagogue

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Demagogue
José Clemente Orozco's painting The Demagogue, 1946

A demagogue (/ˈdɛməˌɡɒɡ/; from Ancient Greek δημαγωγός (dēmagōgós) 'popular leader, mob leader'; from Ancient Greek δῆμος (dêmos) 'people, populace' and ἀγωγός (agōgós) 'leading, guiding') or rabble-rouser, is a political leader in a democracy who gains popularity by arousing the common people against elites, especially through oratory that whips up the passions of crowds, appealing to emotion by scapegoating out-groups, exaggerating dangers to stoke fears, lying for emotional effect, or other rhetoric that tends to drown out reasoned deliberation and encourage fanatical popularity. Demagogues overturn established norms of political conduct, or promise or threaten to do so.

Historian Reinhard Luthin defined demagogue as "a politician skilled in oratory, flattery and invective; evasive in discussing vital issues; promising everything to everybody; appealing to the passions rather than the reason of the public; and arousing racial, religious, and class prejudices—a man whose lust for power without recourse to principle leads him to seek to become a master of the masses. He has for centuries practiced his profession of 'man of the people'. He is a product of a political tradition nearly as old as western civilization itself."

Demagogues have appeared in democracies since ancient Athens. Demagogues exploit a fundamental weakness in democracy: Because ultimate power is held by the people, it is possible for the people to give that power to someone who appeals to the lowest common denominator of a large segment of the population. Demagogues have usually advocated immediate, forceful action to address a crisis while accusing moderate and thoughtful opponents of weakness or disloyalty. Many demagogues elected to high executive office have unraveled constitutional limits on executive power and tried to convert their democracy into a dictatorship, sometimes successfully.

History and definition of the word

A demagogue, in the strict signification of the word, is a 'leader of the rabble'.

— James Fenimore Cooper, "On Demagogues" (1838)

Demagogue, a term originally referring to a leader of the common people, was first coined in ancient Greece with no negative connotation, but eventually came to mean a troublesome kind of leader who occasionally arose in Athenian democracy. Even though democracy gave power to the common people, elections still tended to favor the aristocratic class, which favored deliberation and decorum. Demagogues were a new kind of leader who emerged from the lower classes. Demagogues relentlessly advocated action, usually violent—immediately and without deliberation.

The term "demagogue" has been used to disparage leaders perceived as manipulative, pernicious, or bigoted. However, what distinguishes a demagogue can be defined independently of whether the speaker favors or opposes a certain political leader. A demagogue is defined by how they gain or hold democratic power: by exciting the passions of the lower classes and less-educated people in a democracy toward rash or violent action and breaking established democratic institutions such as the rule of law. James Fenimore Cooper in 1838 identified four fundamental characteristics of demagogues:

  • They present themselves as a man or woman of the common people, opposed to the elites.
  • Their politics depends on a visceral connection with the people, which greatly exceeds ordinary political popularity.
  • They manipulate this connection, and the raging popularity it affords, for their own benefit and ambition.
  • They threaten or outright break established rules of conduct, institutions, and even the law.

Their methods are known as demagoguery or demagogy. The central feature of demagoguery is persuasion by means of passion, shutting down reasoned deliberation and consideration of alternatives. While many politicians in a democracy make occasional small sacrifices of truth, subtlety, or long-term concerns to maintain popular support, demagogues do these things relentlessly and without self-restraint. Demagogues "pander to passion, prejudice, bigotry, and ignorance, rather than reason."

The Austrian philosopher of language and political scientist Paul Sailer-Wlasits [de] differentiates between populism and demagoguery, asserting that "[a] central aspect that distinguishes populism from demagoguery is that demagogues in politics possess substantial systemic power for mobilization, which poses a serious threat to democracy." In political practice, he argues, a clear indication of demagoguery is when "the person, the party, and the political program merge, manifesting as over-identification and over-personalization in a single leading figure."

History and characteristics of demagogues

In every age the vilest specimens of human nature are to be found among demagogues.

— Thomas Macaulay, The History of England from the Accession of James II (1849)

Demagogues have risen to power in democracies from Athens to the present day. While many demagogues have unique, colorful personalities, the psychological tactics they use have been similar throughout history (see below).

Often considered the first demagogue, Cleon of Athens is remembered mainly for the brutality of his rule and his near destruction of Athenian democracy, resulting from his "common-man" appeal to disregard the moderate customs of the aristocratic elite. Modern demagogues include Adolf Hitler, Benito Mussolini, Huey Long, Father Coughlin, and Joseph McCarthy, all of whom built mass followings the same way that Cleon did: by exciting the passions of the masses against customs and norms of the aristocratic elites of their times. All, ancient and modern, meet Cooper's four criteria above: claiming to represent the common people, inciting intense passions among them, exploiting those reactions to take power, and breaking or at least threatening established rules of political conduct, though each in different ways.

Demagogues have often exploited the lower classes and less-educated people in society. While democracies are designed to ensure freedom for all and popular control over government authority, demagogues gain power by using popular support to undermine those same freedoms and laws. The Greek historian Polybius thought that democracies are inevitably undone by demagogues. He said that every democracy eventually decays into "a government of violence and the strong hand", leading to "tumultuous assemblies, massacres, banishments".

While conventional wisdom positions democracy and fascism as opposites, ancient political theorists understood that democracy had an innate tendency to lead to an extreme populist government and provide demagogues with an ideal opportunity to gain power. Ivo Mosley argued that totalitarian regimes may be the logical outcome of unfettered mass democracy.

Emotional oratory and personal charisma

Many demagogues have demonstrated remarkable skill at moving audiences to great emotional depths and heights during a speech. Sometimes this is due to exceptional verbal eloquence, sometimes personal charisma, and sometimes both.

Hitler often began his speeches by speaking slowly, in a low, resonant voice, telling of his life in poverty after serving in World War I, suffering in the chaos and humiliation of postwar Germany, and resolving to reawaken the Fatherland. Gradually, he would escalate the tone and tempo of his speech, ending in a climax in which he shrieked his hatred of Bolsheviks, Jews, Czechs, Poles, or whatever group he currently perceived as standing in his way—mocking them, ridiculing them, insulting them, and threatening them with destruction. Normally reasonable people became caught up in the peculiar rapport that Hitler established with his audience, believing even the most obvious lies and nonsense while under his spell. Hitler was not born with these vocal and oratorical skills; he acquired them through long and deliberate practice.

A more ordinary silver-tongued demagogue was the Negro-baiter James Kimble Vardaman (Governor of Mississippi 1904–1908, Senator 1913–1919), admired even by his opponents for his oratorical gifts and colorful language. An example, responding to Theodore Roosevelt's having invited black people to a reception at the White House: "Let Teddy take coons to the White House. I should not care if the walls of the ancient edifice should become so saturated with the effluvia from the rancid carcasses that a Chinch bug would have to crawl upon the dome to avoid asphyxiation." Vardaman's speeches tended to have little content; he spoke in a ceremonial style even in deliberative settings. His speeches served mostly as a vehicle for his personal magnetism, charming voice, and graceful delivery.

The demagogues' charisma and emotional oratory many times enabled them to win elections despite opposition from the press. The news media informs voters, and often the information is damaging to demagogues. Demagogic oratory distracts, entertains, and enthralls, steering followers' attention away from the demagogue's usual history of lies, abuses of power, and broken promises. The advent of radio enabled many 20th-century demagogues' skill with the spoken word to drown out the written word of newspapers.

Tactics

There are a number of common tactics demagogues have employed throughout history to manipulate public sentiment and incite crowds. Not all demagogues use all of these methods, and no two demagogues use exactly the same methods to gain popularity and loyalty. Even ordinary politicians use some of these techniques from time to time; a politician who failed to stir emotions at all would have little hope of being elected. What these techniques have in common, and what distinguishes demagogues' use of them, is their consistent intent to prevent reasoned deliberation by stirring up overwhelming passion.

In contrast to a demagogue, a politician's ordinary rhetoric seeks "to calm rather than excite, to conciliate rather than divide, and to instruct rather than flatter."

Scapegoating

The most fundamental demagogic technique is scapegoating: blaming the in-group's troubles on an out-group, usually of a different ethnicity, religion, or social class. For example, McCarthy claimed that all of the problems of the U.S. resulted from "communist subversion." Denis Kearney blamed all the problems of laborers in California on Chinese immigrants. Hitler blamed Jews for Germany's defeat in World War I as well as the economic troubles that came afterward. This was central to his appeal: many people said that the only reason they liked Hitler was because he was against the Jews. Fixing blame on the Jews gave Hitler a way to intensify nationalism and unity.

The claims made about the scapegoated class are mostly the same regardless of the demagogue and regardless of the scapegoated class or the nature of the crisis that the demagogue is exploiting. "We" are the "true" Americans/​Germans/​Christians/etc., and "they", the Jews/​bankers/​communists/​capitalists/​unions/​foreigners/​elites/​etc., have cheated "us" plain folk and are living in decadent luxury off riches that rightfully belong to "us". "They" are plotting to take over, are now rapidly taking power, or are already secretly running the country. "They" are subhuman, sexual perverts who will seduce or rape "our" daughters, and if "we" do not expel or exterminate "them" right away, doom is just around the corner.

Fearmongering

Many demagogues have risen to power by evoking fear in their audiences, to stir them to action and prevent deliberation. Fear of rape, for example, is easily evoked. "Pitchfork Ben" Tillman's rhetoric was most vivid when he was describing imaginary scenes in which white women were raped by black men lurking by the side of the road. He depicted black men as having an innate "character weakness" consisting of a fondness for raping white women. Tillman was elected governor of South Carolina in 1890, and elected senator repeatedly from 1895 to 1918.

After the September 11 attacks in the United States, terrorism and national security became prominent political issues. After Democrats lost control of the Congress in 2004, former U.S. president Bill Clinton opined: "When people are feeling insecure, they'd rather have someone who is strong and wrong rather than somebody who is weak and right." The Clinton aphorism was later applied to describe why the political tactics of Donald Trump were successful, and how Democrats might do better in related elections.

Lying

Demagogues typically choose their words for their emotional effect on the audience, often without regard for factual truth or for potential danger. Demagogues are opportunistic, saying whatever will generate controversy and spur public energy. Other demagogues may believe falsehoods they tell.

If one lie does not work, a demagogue often adds more lies. Joseph McCarthy claimed to have a list of 205 members of the Communist Party working in the State Department. Then, he announced there were 57 "card-carrying Communists". When pressed for names, McCarthy said that records were not available to him, but he knew "absolutely" that "approximately" 300 Communists were certified to the Secretary of State for discharge but "approximately" 80 were actually discharged. McCarthy never found a Communist in the State Department.

Accusing opponents of weakness and disloyalty

Cleon of Athens, like many demagogues who came after him, constantly advocated brutality in order to demonstrate strength, and argued that compassion was a sign of weakness that would only be exploited by enemies. "It is a general rule of human nature that people despise those who treat them well and look up to those who make no concessions." At the Mytilenian Debate over whether to recall the ships he had sent the previous day to slaughter and enslave the entire population of Mytilene, he opposed the very idea of debate, characterizing it as an idle, weak, intellectual pleasure: "To feel pity, to be carried away by the pleasure of hearing a clever argument, to listen to the claims of decency are three things that are entirely against the interests of an imperial power."

Distracting from his lack of evidence for his claims, Joe McCarthy persistently insinuated that anyone who opposed him was a communist sympathizer. G.M. Gilbert summarized this rhetoric as "I'm agin' Communism; you're agin' me; therefore you must be a communist."

Promising the impossible

Another fundamental demagogic technique is making promises only for their emotional effect on audiences, without regard for how they might be accomplished or without intending to honor them once in office. Demagogues express these empty promises simply and theatrically, but remain extremely hazy about how they will achieve them because usually they are impossible. For example, Huey Long promised that if he were elected president, every family would have a home, an automobile, a radio, and $2,000 yearly. He was vague about how he would make that happen, but people still joined his Share-the-Wealth clubs. Another kind of empty demagogic promise is to make everyone wealthy or "solve all the problems". The Polish demagogue Stanisław Tymiński, running as an unknown "maverick" on the basis of his prior success as a businessman in Canada, promised "immediate prosperity"—exploiting the economic difficulties of laborers, especially miners and steelworkers. Tymiński forced a runoff in the 1990 presidential election, nearly defeating Lech Wałęsa.

Encouraging violence and using physical intimidation

Demagogues have often encouraged their supporters to violently intimidate opponents, both to solidify loyalty among their supporters and to discourage or physically prevent people from speaking out or voting against them. "Pitchfork Ben" Tillman was repeatedly re-elected to the U.S. Senate largely through violence and intimidation. He spoke in support of lynch mobs, and he disenfranchised most black voters with the South Carolina constitution of 1895. Hitler wrote in Mein Kampf that physical intimidation was an effective way to move the masses. Hitler intentionally provoked hecklers at his rallies so that his supporters would become enraged by their remarks and assault them.

Personal insults and ridicule

Many demagogues have found that ridiculing or insulting opponents is a simple way to shut down reasoned deliberation of competing ideas, especially with an unsophisticated audience. "Pitchfork Ben" Tillman, for example, was a master of the personal insult. He got his nickname from a speech in which he called President Grover Cleveland "an old bag of beef" and resolved to bring a pitchfork to Washington to "poke him in his old fat ribs." James Kimble Vardaman consistently referred to President Theodore Roosevelt as a "coon-flavored miscegenationist" and once posted an ad in a newspaper for "sixteen big, fat, mellow, rancid coons" to sleep with Roosevelt during a trip to Mississippi.

A common demagogic technique is to pin an insulting epithet on an opponent, by saying it repeatedly, in speech after speech, when saying the opponent's name or in place of it. For example, James Curley referred to Henry Cabot Lodge Jr., his Republican opponent for Senator, as "Little Boy Blue". William Hale Thompson called Anton Cermak, his opponent for mayor of Chicago, "Tony Baloney". Huey Long called Joseph E. Ransdell, his elderly opponent for Senator, "Old Feather Duster". Joe McCarthy liked to call Secretary of State Dean Acheson "The Red Dean of Fashion". The use of epithets and other humorous invective diverts followers' attention from soberly considering how to address the important public issues of the time, scoring easy laughs instead.

Exhibiting vulgarity and behaving outrageously

Legislative bodies usually have sober standards of decorum that are intended to quiet passions and favor reasoned deliberation. Many demagogues violate standards of decorum outrageously, to show clearly that they are thumbing their noses at the established order and the genteel ways of the upper class, or simply because they enjoy the attention that it brings. The common people might find the demagogue disgusting, but the demagogue can use the upper class's contempt for him to show that he will not be shamed or intimidated by the powerful.

For example, Huey Long famously wore pajamas to highly dignified occasions where others were dressed at the height of formality. He once stood "bukk nekkid" at his hotel suite when laying down the law to a meeting of political fuglemen. Long was "intensely and solely interested in himself. He had to dominate every scene he was in and every person around him. He craved attention and would go to almost any length to get it. He knew that an audacious action, although it was harsh and even barbarous, could shock people into a state where they could be manipulated." He was "...so shameless in his pursuit of publicity, and so adept at getting press coverage, that he was soon attracting more attention from the press and the galleries than most of the rest of his colleagues combined."

In ancient Greece, Aristotle pointed out the bad manners of Cleon more than 2,000 years ago: "[Cleon] was the first who shouted on the public platform, who used abusive language and who spoke with his cloak girt about him, while all the others used to speak in proper dress and manner."

Folksy posturing

Demagogues often make a show of appearing to be down-to-earth, ordinary citizens just like the people whose votes they seek. In the United States, many took folksy nicknames: William H. Murray (1869–1956) was "Alfalfa Bill"; James M. Curley (1874–1958) of Boston was "Our Jim"; Ellison D. Smith (1864–1944) was "Cotton Ed"; the husband-and-wife demagogue team of Miriam and James E. Ferguson went by "Ma and Pa"; Texas governor W. Lee O'Daniel (1890–1969) was "Pappy-Pass-the-Biscuits".

Georgia governor Eugene Talmadge (1884–1946) put a barn and a henhouse on the executive mansion grounds, loudly explaining that he could not sleep nights unless he heard the bellowing of livestock and the cackling of poultry. When in the presence of farmers, he chewed tobacco and faked a rural accent—though he himself was college-educated—railing against "frills" and "nigger-lovin' furriners". Talamadge defined "furriner" as "Anyone who attempts to impose ideas that are contrary to the established traditions of Georgia." His grammar and vocabulary became more refined when speaking before an urban audience. Talmadge was famous for wearing gaudy red galluses, which he snapped for emphasis during his speeches. On his desk, he kept three books that he loudly told visitors were all that a governor needed: a bible, the state financial report, and a Sears–Roebuck catalog.

Huey Long emphasized his humble roots by calling himself "The Kingfish" and gulping down pot likker when visiting northern Louisiana. He once issued a press release demanding that his name be removed from the Washington Social Register. "Alfalfa Bill" made sure to remind people of his rural background by talking in the terminology of farming: "I will plow straight furrows and blast all the stumps. The common people and I can lick the whole lousy gang."

Making gross oversimplification

Demagogues commonly treat complex problems, which require patient reasoning and analysis, as if they result from one simple cause or can be solved by one simple cure. For example, Huey Long claimed that all of the U.S.'s economic problems could be solved just by "sharing the wealth". Hitler claimed that Germany had lost World War I only because of a "Stab in the Back". Scapegoating (above) is one form of gross oversimplification.

Attacking the news media

Because factual information reported by the press can undermine a demagogue's claims and standing among followers, modern demagogues have attacked the press intemperately. At times, demagogues have called for violence against newspapers who opposed them. Some have claimed that the press was acting secretly in the service of moneyed interests or foreign powers or that newspapers had a personal vendetta against them. Huey Long accused the New Orleans Times–Picayune and Item of being "bought", and had his bodyguards rough up their reporters. Oklahoma governor "Alfalfa Bill" Murray (1869–1956) once called for a bomb to be dropped on the offices of the Daily Oklahoman. Joe McCarthy accused The Christian Science Monitor, the New York Post, The New York Times, the New York Herald Tribune, The Washington Post, the St. Louis Post-Dispatch, and other leading American newspapers of being "Communist smear sheets" under the control of the Kremlin.

Actions in power

The shortest way to ruin a country is to give power to demagogues.

— Dionysius of Halicarnassus, Antiquities of Rome, VI (20 BC)

Establishing one-man rule, subverting the rule of law

In executive office, demagogues have often moved quickly to expand their power, both de jure and de facto: by getting legislation passed to officially expand their authority, and by building up networks of corruption and informal pressure to ensure that their dictates are followed regardless of constitutional authority.

For example, within two months of being appointed chancellor, Hitler unraveled all constitutional limitations on his power. He achieved this through near-daily acts of chaos, destabilizing the state and providing ever stronger reasons to justify taking more power. Hitler was appointed on January 30, 1933; on February 1, the Reichstag was dissolved; on February 27, the Reichstag building burned; on February 28, the Reichstag Fire Decree gave Hitler emergency powers and suspended civil liberties; on March 5, new general elections were held; on March 22, the first concentration camp opened, taking political prisoners. On March 24, the Enabling Act was passed, giving Hitler full legislative powers, thus ending all constitutional restraint and making Hitler absolute dictator. Consolidation of power continued even after that; see Early timeline of Nazism.

Even local demagogues have established one-man rule, or a near approximation of it, over their constituencies. "Alfalfa Bill" Murray, a demagogue who was elected governor of Oklahoma by appealing to poor rural animosity toward "craven wolves of plutocracy", promised to "make an open season on millionaires." Despite having presided over Oklahoma's constitutional convention, Murray routinely violated the constitution, ruling by executive order whenever the legislature or the courts got in his way. When federal courts ruled against him, he prevailed by relying on the National Guard, even donning a military hat and pistol and personally commanding the troops—and seeing to it that the confrontation was filmed by movie cameras. Murray attempted to expand gubernatorial powers with a set of four initiatives, replacing existing income-tax law with his own, giving him power to appoint all members of the board of education, acquiring corporation-owned land, and giving him extraordinary power over the budget, but these were defeated.

Appointing unqualified lackeys to high office

Demagogues often appoint people to high office based on personal loyalty without regard to competence for the office—opening up extraordinary avenues for graft and corruption. During "Alfalfa Bill" Murray's campaign for governor, he promised to crack down on corruption and favoritism for the rich, to abolish half the clerk jobs at the State House, to appoint no family members, to reduce the number of state-owned cars from 800 to 200, never to use convict labor to compete with commercial labor, and not to abuse the power of pardon. Once in office, he appointed wealthy patrons and 20 of his relatives to high office, purchased more cars, used prisoners to make ice for sale and clean the capitol building, and violated all the other promises. When the State Auditor pointed out that 1,050 new employees had been added to the state payroll, Murray simply said, "Just damned lies." For each abuse of power, Murray claimed a mandate from "the sovereign will of the people".

Famous historical demagogues

Ancient history

Cleon (died 422 BC)

The Athenian leader Cleon is often cited as a demagogue because of three events described in the writings of Thucydides and Aristophanes.

First, after a failed revolt by the city of Mytilene, Cleon persuaded the Athenians to slaughter not just the Mytilenean prisoners, but every man in the city, and to sell their wives and children as slaves. The Athenians rescinded the resolution the following day when they came to their senses.

Second, after Athens had completely defeated the Peloponnesian fleet in the Battle of Sphacteria and Sparta could only beg for peace on almost any terms, Cleon persuaded the Athenians to reject the peace offer.

Third, he taunted the Athenian generals over their failure to bring the war in Sphacteria to a rapid close, accusing them of cowardice, and declared that he could finish the job himself in 20 days, despite having no military knowledge. They gave him the job, expecting him to fail. Cleon shrank at being called to make good on his boast, and tried to get out of it, but he was forced to take the command. In fact, he succeeded—by getting the general Demosthenes to do it, now treating him with respect after previously slandering him behind his back. Three years later, Cleon and his Spartan counterpart Brasidas were killed at the Battle of Amphipolis, enabling a restoration of peace that lasted until the outbreak of the Second Peloponnesian War.

Modern commentators suspect that Thucydides and Aristophanes exaggerated the vileness of Cleon's real character. Both had personal conflicts with Cleon, and The Knights is a satirical, allegorical comedy that does not even mention Cleon by name. Cleon was a tradesman—a leather-tanner. Thucydides and Aristophanes came from the upper classes, predisposed to look down on the commercial classes. Nevertheless, their portrayals define the archetypal example of the "demagogue" or "rabble-rouser".

Alcibiades (c.450–404 BC)

Alcibiades convinced the people of Athens to attempt to conquer Sicily during the Peloponnesian War, with disastrous results. He led the Athenian assembly to support making him commander by claiming victory would come easily, appealing to Athenian vanity, and appealing to action and courage over deliberation. Alcibiades's expedition might have succeeded if he had not been denied command by the political maneuvers of his rivals.

Gaius Flaminius (c. 275–217 BC)

Gaius Flaminius was a Roman consul most known for being defeated by Hannibal at the Battle of Lake Trasimene during the second Punic war. Hannibal was able to make pivotal decisions during this battle because he understood his opponent. Flaminius was described as a demagogue by Polybius, in his book The Histories "...Flaminius possessed a rare talent for the arts of demagogy..." Because Flaminius was thus ill-suited, he lost 15,000 Roman lives, his own included, in the battle.

Modern era

Adolf Hitler (1889–1945)

The most famous demagogue of modern history, Adolf Hitler, first attempted to overthrow the Bavarian government not with popular support but by force in a failed putsch in 1923. While in prison, Hitler chose a new strategy: to overthrow the government democratically, by cultivating a mass movement. Even before the putsch, Hitler had rewritten the Nazi party's platform to consciously appeal to the lower classes of Germany, appealing to their resentment of wealthier classes and calling for German unity and increased central power. Hitler was delighted by the instant increase in popularity.

While Hitler was in prison, the Nazi party vote had fallen to one million, and it continued to fall after Hitler was released in 1924 and began rejuvenating the party. For the next several years, Hitler and the Nazi party were generally regarded as a laughingstock in Germany, no longer taken seriously as a threat to the country. The prime minister of Bavaria lifted the region's ban on the party, saying, "The wild beast is checked. We can afford to loosen the chain."

In 1929, with the start of the Great Depression, Hitler's populism started to become effective. Hitler updated the Nazi party's platform to exploit the economic distress of ordinary Germans: repudiating the Versailles Treaty, promising to eliminate corruption, and pledging to provide every German with a job. In 1930, the Nazi party went from 200,000 votes to 6.4 million, making it the second-largest party in Parliament. By 1932, the Nazi party had become the largest in Parliament. In early 1933, Hitler was appointed Chancellor. He then exploited the Reichstag fire to arrest his political opponents and consolidate his control of the army. Within a few years, enjoying democratic support from the masses, Hitler took Germany from a democracy to a total dictatorship.

Huey Long, governor of Louisiana

Huey Long (1893–1935)

Huey Long, nicknamed "The Kingfish", was an American politician who served as the 40th governor of Louisiana from 1928 to 1932 and as a member of the United States Senate from 1932 until his assassination in 1935. He was a populist member of the Democratic Party and rose to national prominence during the Great Depression for his vocal criticism from the left of President Franklin D. Roosevelt and his New Deal. As the political leader of Louisiana, he commanded wide networks of supporters and often took forceful action. A controversial figure, Long is celebrated as a populist benefactor or conversely denounced as a fascist demagogue.

In 1928, before Long was sworn in as governor of Louisiana, he was already supervising political appointments to ensure a loyal majority for all his initiatives. As governor, he ousted public officers not personally loyal to him and took control away from state commissions to ensure that all contracts would be awarded to people in his political machine. In a confrontation over natural gas with managers of the Public Service Corporation, he told them, truthfully, "A deck has 52 cards and in Baton Rouge I hold all 52 of them and I can shuffle and deal as I please. I can have bills passed or I can kill them. I'll give you until Saturday to decide." They yielded to Long—and became part of his ever-expanding machine.

When Long became a senator in 1932, his enemy, the lieutenant governor Paul N. Cyr, was sworn in as governor. Long, without authority, ordered state troopers to surround the executive mansion and arrest Cyr as an imposter. Long installed his ally Alvin O. King as governor, later replaced by O.K. Allen, serving as stooges for Long. Thus even in Washington, with no official authority, Long retained dictatorial control over Louisiana. When the Mayor of New Orleans, T. Semmes Walmsley, began to oppose Long's extraordinary power over the state, Long exploited a subservient judge to justify making an armed attack on the basis of cracking down on racketeering. At Long's order, Governor Allen declared martial law and dispatched National Guardsmen to seize the Registrar of Voters, allegedly "to prevent election frauds". Then, by stuffing ballot boxes, Long ensured victory for his candidates to Congress. Long's own racketeering operation then grew. With his "trained seal" legislature, armed militias, taxation used as a political weapon, control over elections, and weakened court authority to limit his power, Huey Long maintained control in Louisiana in a manner arguably comparable to that of a dictator.

Senator Joseph McCarthy, an American demagogue

Joseph McCarthy (1908–1957)

Joseph McCarthy was a U.S. Senator from the state of Wisconsin from 1947 to 1957. Though a poor orator, McCarthy rose to national prominence during the early 1950s by proclaiming that high places in the United States federal government and military were "infested" with communists, contributing to the second "Red Scare". Ultimately, his inability to provide proof for his claims, as well as his public attacks on the United States Army, led to the Army–McCarthy hearings in 1954, which in turn led to his censure by the Senate and fall from popularity.

Donald Trump

Multiple sources have described Donald Trump as a demagogue.

Positive demagoguery

Tactical demagoguery

Some scholars have challenged the consensus that demagoguery is necessarily a bad form of leadership and rhetoric. In Demagogues in American Politics, for example, Charles U. Zug argues that demagoguery can be legitimate and even good if integrated into a broader strategy for political reform and if coupled with a robust rationale for political change. Zug contrasts classical or traditional approaches to demagoguery, which assume that demagogues are motivated by vicious intentions (such as an unrestrained desire for power), with a modern approach that focuses on the external words and deeds that demagogues use to advance political goals. Relatedly, as Princeton Classicist Melissa Lane has argued, in pre-Socratic antiquity demagogues were originally viewed as neither inherently good nor inherently bad, but rather as advocates for the common people (as opposed to the oligarchs). Zug has argued that conceiving of demagoguery as an inherently negative practice incentivizes political actors to weaponize the label "demagogue"; as a consequence, otherwise innocent victims—such as the supposed leader of Shays' Rebellion, Daniel Shays—can be inaccurately branded as vicious, unscrupulous leaders.

Demagoguery in constitutional office

Zug also argues that demagoguery takes on different meanings when deployed by public officials in different institutions; for example, American federal judges should be scrutinized more carefully for using demagoguery than should legislators, since the act of judging well—i.e., adjudicating legal disputes—does not require direct appeals to the public. In contrast, being an effective member of Congress requires advocating for a constituency and getting (re)elected; and these responsibilities in turn require direct public appeals, and sometimes, demagoguery.

Sophist

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

A sophist (Greek: σοφιστής, romanizedsophistēs) was a teacher in ancient Greece in the fifth and fourth centuries BC. Sophists specialized in one or more subject areas, such as philosophy, rhetoric, music, athletics and mathematics. They taught arete, "virtue" or "excellence", predominantly to young statesmen and nobility.

The arts of the sophists were known as sophistry and gained a negative reputation as tools of arbitrary reasoning. Protagoras, regarded as the first of the sophists, became notorious for his claim to "make the weaker argument the stronger".

In modern usage, sophism, sophist, and sophistry are used disparagingly. Sophistry, or a sophism, is a fallacious argument, especially one used deliberately to deceive. A sophist is a person who reasons with clever but deceptive or intellectually dishonest arguments.[4][5]

Etymology

The Greek word σοφός, sophos, 'a wise man' is related to the noun σοφία, sophia, 'wisdom'. Since the times of Homer, it commonly referred to an expert in his profession or craft. Charioteers, sculptors, or military experts could be referred to as sophoi in their occupations. The word has gradually come to connote general wisdom and especially wisdom in human affairs such as politics, ethics, and 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.

The word σοφός gives rise to the verb σοφίζω, sophizo, 'to instruct / make learned', the passive voice of which means "to become or be wise", or "to be clever or skilled". From the verb is derived the noun σοφιστής, sophistes, which originally meant "a master of one's craft" and later "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

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. Nicholas Denyer observes that the Sophists "did ... 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 speciality 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.

The Greeks were "experimenting with a new form of government, democracy" (W. Keith, 5). Therefore, they were navigating how to make decisions without a higher authority. They needed to create laws based on demand and popular vote of the people. Back in the fifth century they did not have mass media, printing presses, and barely any texts. They mostly relied on speech. This meant that "the Athenians needed a strategy for effectively talking to other people in juries, in forums, and in the senate" (W. Keith, 5). This is when the sophist began to come about. Originally known as Sicilians, they began to teach Athenians how to speak in a persuasive manner in order to work with the courts and senate. It is not really known how these Sicilians, who came to be Sophists, initially grew an interest to teach others how to speak persuasively. However, the interest in receiving training from the Sophists increased. (The Origins of Rhetoric Keith & Lundberg)

Sophists could be described both as teachers and philosophers, having travelled 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 arete ("excellence" or "virtue") in the management and administration of not only one's affairs, but the city's as well. Before the 5th century BC, it was believed that aristocratic birth qualified a person for arete and politics. However, Protagoras, who is regarded as the first sophist, argued that arete was the result of training rather than birth.

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.

Xeniades

Xeniades was a skeptical philosopher from Corinth, probably a follower of the pre-Socratic Xenophanes. There may have been two such persons, as he is referenced by Democritus c. 400 BC, though he was also supposedly the purchaser of Diogenes the Cynic c. 350 BC, when he was captured by pirates and sold as a slave. Xeniades was supposed to have been the man who persuaded Monimus to become a follower of Diogenes, and was the source of his skeptical doctrines. The little that is known of him is derived from Sextus Empiricus, who represents him as holding the most ultrasceptical opinions, and maintaining that all notions are false, and that there is absolutely nothing true in the universe. He more than once couples him with Xenophanes.

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.

Lycophron

Lycophron is mentioned as a sophist by Aristotle, and was probably among the students of Gorgias. He rejected the supposed value of an aristocratic birth, claiming that "Now the nobility of good birth is obscure, and its grandeur a matter of words." meaning that there is no factual difference between those well-born and those low-born; only words and opinion assign value to these different circumstances of birth. This statement may indicate that Lycophron shared the beliefs of Antiphon, that (regardless of their ancestry) both Greeks and barbarians are born with the same capacities: An egalitarian belief that was a minority view in the 5th century BC. He is also known for his statement (reproduced by Aristotle, in the latter's Politics, 1280b10), that "law is only a convention, a surety to another of justice", also translated as "a guarantor of men's rights against one another". He, thus, believed that law is a matter of agreement, a social convention and not a natural or universal standard (there is no evidence that Lycophron rejected the idea that law is a universal standard – indeed his view appears far more universalist than that of Aristotle, in that Lycophron proposes a single standard, what would now be called the non aggression principle, in relation to all states). In this respect his views on law are similar to those of Protagoras. This means that he treats law as a mere means, in the context of a (perhaps primitive) social contract theory, without considering it as something special, in contradistinction to, e.g., Plato but similar to both Thrasymachus and Callicles, albeit that their theories have – as far as can be ascertained from the information available about them – more specific characteristics.

Criticism

Socrates was lampooned by Aristophanes in The Clouds as a pedantic wordsmith who lived in a basket. Later philosophers such as Plato and Xenophon sought to distinguish Socrates' ethical teachings from this comic portrayal of a sophist.

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. As there was a popular view of Socrates as a sophist, he was among the targets (which prompted a vigorous condemnation from his followers, including Plato and Xenophon). For example, in the comic play The Clouds, Aristophanes criticizes the sophists as hairsplitting wordsmiths, and makes Socrates their representative. Such criticism, coupled with the wealth garnered by many sophist practitioners, eventually led to popular resentment against sophists and the ideas and writings associated with sophism.

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 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.

Isocrates, one of the later sophists, was critical of the education practices of his predecessors

Isocrates

One of the few speeches that have survived from ancient Greece is Isocrates' Against the Sophists. The speech offers scathing criticisms against sophist teachers and their failures.

While a sophist himself, Isocrates sought to distinguish his school's pedagogical focus from other sophistic teachings. In particular, Isocrates wanted to establish an institution that educated Athenian students in a manner that would promote the success of Athenian democracy. By developing a school in Athens around 392 BC, approximately five years after Plato opened his Platonic Academy, Isocrates gave sophism more credibility in society.

Plato

As only small portions of the sophists' writings have survived they are mainly known through the works of Plato. Plato's dialogues present a generally hostile view on the sophists' thought, which is largely responsible for the modern view of the sophist as an avaricious instructor that teaches deception.

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. 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

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 Plato through Socrates 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.

Democracy

The sophists' rhetorical techniques were useful for any young nobleman seeking 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 contradictions. These means distinguished the speeches of the sophists from the other speakers. Contradictions (antithesis ) 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 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 path for the audience to the argument offered, varying depending on the type of speech and audience.

Rome

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 5th century BC. 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.

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.

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 Philostratus, 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 Nicetes of Smyrna, in the late 1st century CE. 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".

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.
