Sophisme Un article de Wikipédia, l'encyclopédie libre. Un sophisme est une argumentation à la logique fallacieuse. C'est un raisonnement qui cherche à paraître rigoureux mais qui n'est en réalité pas valide au sens de la logique (quand bien même sa conclusion serait pourtant la « vraie »). À l'inverse du paralogisme, qui est une erreur dans un raisonnement, le sophisme est fallacieux : il est prononcé avec l'intention de tromper l'auditoire afin, par exemple, de prendre l'avantage dans une discussion. Souvent, les sophismes prennent l'apparence d'un syllogisme (qui repose sur des prémisses insuffisantes ou non-pertinentes ou qui procède par enthymème, etc.). Ils peuvent aussi s'appuyer sur d'autres mécanismes psychologiques jouant par exemple avec l'émotion de l'auditoire, l'ascendant social du locuteur (argument d'autorité) ou des biais cognitifs (comme l'oubli de la fréquence de base).

List of common misconceptions From Wikipedia, the free encyclopedia Each entry on this list of common misconceptions is worded as a correction; the misconceptions themselves are implied rather than stated. These entries are concise summaries; the main subject articles can be consulted for more detail. A common misconception is a viewpoint or factoid that is often accepted as true but which is actually false. They generally arise from conventional wisdom (such as old wives' tales), stereotypes, superstitions, fallacies, a misunderstanding of science, or the popularization of pseudoscience.

Teaching and Promoting Logical & Critical Thinking List of Fallacies A fallacy is incorrect argument in logic and rhetoric resulting in a lack of validity, or more generally, a lack of soundness. Fallacies are either formal fallacies or informal fallacies. Formal fallacies[edit] Main article: Formal fallacy Appeal to probability – is a statement that takes something for granted because it would probably be the case (or might be the case).[2][3]Argument from fallacy – assumes that if an argument for some conclusion is fallacious, then the conclusion is false.Base rate fallacy – making a probability judgment based on conditional probabilities, without taking into account the effect of prior probabilities.[5]Conjunction fallacy – assumption that an outcome simultaneously satisfying multiple conditions is more probable than an outcome satisfying a single one of them.[6]Masked man fallacy (illicit substitution of identicals) – the substitution of identical designators in a true statement can lead to a false one. Propositional fallacies[edit]
Disinformation Disinformation is intentionally false or inaccurate information that is spread deliberately. It is an act of deception and false statements to convince someone of untruth. Disinformation should not be confused with misinformation, information that is unintentionally false. Unlike traditional propaganda techniques designed to engage emotional support, disinformation is designed to manipulate the audience at the rational level by either discrediting conflicting information or supporting false conclusions. A common disinformation tactic is to mix some truth and observation with false conclusions and lies, or to reveal part of the truth while presenting it as the whole (a limited hangout). Another technique of concealing facts, or censorship, is also used if the group can affect such control. Examples[edit] In espionage or military intelligence, disinformation is the deliberate spreading of false information to mislead an enemy as to one's position or course of action.

SCHOPENHAUER'S 38 STRATAGEMS, OR 38 WAYS TO WIN AN ARGUMENT Arthur Schopenhauer (1788-1860), was a brilliant German philosopher. These 38 Stratagems are excerpts from "The Art of Controversy", first translated into English and published in 1896. Carry your opponent's proposition beyond its natural limits; exaggerate it. (abstracted from the book:Numerical Lists You Never Knew or Once Knew and Probably Forget, by: John Boswell and Dan Starer) Misinformation Misinformation is false or inaccurate information that is spread unintentionally. It is distinguished from disinformation, which is intended to mislead.[1] When comparing misinformation to disinformation, Jürgen Habermas says that the motives play an active role in the effect the information has. Misinformation may have a less devastating effect in that readers can criticize what they have read and evaluate it as truth or fiction. Authors will also have to give reasoning for their beliefs and support their statements with facts.[2] Sources[edit] In an age of technological advances, social networking sites are becoming more and more popular. Identification[edit] According to Anne Mintz, editor of Web of Deception: Misinformation on the Internet, the best ways to find if information is factual is to use common sense. Examples[edit] Social media sites have allowed citizens to spread false information about any topic they find. Causes[edit] Misinformation is spread for numerous reasons.
The Art of Being Right The Art of Being Right: 38 Ways to Win an Argument (1831) (Eristische Dialektik: Die Kunst, Recht zu Behalten) is an acidulous and sarcastic treatise written by the German philosopher Arthur Schopenhauer in sarcastic deadpan.[1] In it, Schopenhauer examines a total of thirty-eight methods of showing up one's opponent in a debate. He introduces his essay with the idea that philosophers have concentrated in ample measure on the rules of logic, but have not (especially since the time of Immanuel Kant) engaged with the darker art of the dialectic, of controversy. Whereas the purpose of logic is classically said to be a method of arriving at the truth, dialectic, says Schopenhauer, "...on the other hand, would treat of the intercourse between two rational beings who, because they are rational, ought to think in common, but who, as soon as they cease to agree like two clocks keeping exactly the same time, create a disputation, or intellectual contest."

La Dialectique éristique Un article de Wikipédia, l'encyclopédie libre. Définition[modifier | modifier le code] « La dialectique éristique est l'art de la controverse. » Cet art repose sur la distinction entre la vérité objective d'une proposition et l'apparence de vérité que cette proposition peut prendre aux yeux des disputeurs et des auditeurs. Causes et fonctions de la dialectique[modifier | modifier le code] Si les hommes étaient honnêtes, il n'y aurait pas de dialectique. la malhonnêteté ;la vanité ;le fait de parler avant de réfléchir ;l'obstination dans l'erreur. Une autre cause est que l'expérience enseigne que lorsque nos arguments en faveur d'une thèse sont réfutés, il pourra toujours se trouver un nouvel argument qui nous donnera finalement raison. Le résultat de cet ensemble est que tout homme veut que sa thèse paraisse vraie, même (et surtout) quand il sait qu'elle est fausse. En conséquence, les moyens de cet art relèvent de la ruse et de l'adresse ; chacun en est pourvu, quoique de manière inégale.

Rhetoric Painting depicting a lecture in a knight academy, painted by Pieter Isaacsz or Reinhold Timm for Rosenborg Castle as part of a series of seven paintings depicting the seven independent arts. This painting illustrates rhetorics. From Ancient Greece to the late 19th century, it was a central part of Western education, filling the need to train public speakers and writers to move audiences to action with arguments.[4] The word is derived from the Greek ῥητορικός (rhētorikós), "oratorical",[5] from ῥήτωρ (rhḗtōr), "public speaker",[6] related to ῥῆμα (rhêma), "that which is said or spoken, word, saying",[7] and ultimately derived from the verb ἐρῶ (erō), "say, speak".[8] Uses of rhetoric[edit] Scope of rhetoric[edit] Scholars have debated the scope of rhetoric since ancient times. Because the ancient Greeks highly valued public political participation, rhetoric emerged as a crucial tool to influence politics. However, since the time of Aristotle, logic has changed.
Nocebo In medicine, a nocebo (Latin for "I shall harm") is a harmless substance that creates harmful effects in a patient who takes it. The nocebo effect is the negative reaction experienced by a patient who receives a nocebo. Conversely, a placebo is an inert substance that creates either a positive response or a negative response in a patient who takes it. Both nocebo and placebo effects are entirely psychogenic. Etymology[edit] The term nocebo (Latin nocēbō, "I shall harm", from noceō, "I harm")[3] was chosen by Walter Kennedy, in 1961, to denote the counterpart of one of the more recent applications of the term placebo (Latin placēbō, "I shall please", from placeō, "I please");[4] namely, that of a placebo being a drug that produced a beneficial, healthy, pleasant, or desirable consequence in a subject, as a direct result of that subject's beliefs and expectations. Description[edit] W.R. ... Houston spoke of three significantly different categories of placebo (pp.1417-1418): Response[edit]
