Rhétorique Un article de Wikipédia, l'encyclopédie libre. Au-delà de cette définition générale, la rhétorique a connu au cours de son histoire une tension entre deux conceptions antagonistes, la rhétorique comme art de la persuasion et la rhétorique comme art de l'éloquence. La rhétorique grecque, telle qu'elle fut pratiquée par les sophistes et codifiée par Aristote, se préoccupait principalement de persuader. Problématiques de la rhétorique[modifier | modifier le code] Polémiques autour d'une définition[modifier | modifier le code] Marc Fumaroli comme Joëlle Gardes-Tamine ont étudié les conceptions de la rhétorique au cours des siècles et relèvent que celles-ci peuvent se rattacher à deux traditions philosophiques[4] : la définition d'origine sophistique, selon laquelle la rhétorique doit persuader. Les recherches contemporaines ont disséqué la rhétorique et les interprétations se sont multipliées. Trois notions centrales : le logos, le pathos et l'êthos[modifier | modifier le code] Pour J.

There are two main types of arguments: deductive and inductive. A fallacy is, very generally, an error in reasoning.

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.

Logical Fallacies 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.

Top 10 Thinking Traps Exposed Our minds set up many traps for us. Unless we’re aware of them, these traps can seriously hinder our ability to think rationally, leading us to bad reasoning and making stupid decisions. Features of our minds that are meant to help us may, eventually, get us into trouble. Here are the first 5 of the most harmful of these traps and how to avoid each one of them. 1. “Is the population of Turkey greater than 35 million? Lesson: Your starting point can heavily bias your thinking: initial impressions, ideas, estimates or data “anchor” subsequent thoughts. This trap is particularly dangerous as it’s deliberately used in many occasions, such as by experienced salesmen, who will show you a higher-priced item first, “anchoring” that price in your mind, for example. What can you do about it? Always view a problem from different perspectives. 2. In one experiment a group of people were randomly given one of two gifts — half received a decorated mug, the other half a large Swiss chocolate bar. 3. 4.

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."

Top 10 Common Faults In Human Thought Humans The human mind is a wonderful thing. Cognition, the act or process of thinking, enables us to process vast amounts of information quickly. For example, every time your eyes are open, you brain is constantly being bombarded with stimuli. The Gambler’s fallacy is the tendency to think that future probabilities are altered by past events, when in reality, they are not. Reactivity is the tendency of people to act or appear differently when they know that they are being observed. Pareidolia is when random images or sounds are perceived as significant. Interesting Fact: the Rorschach Inkblot test was developed to use pareidolia to tap into people’s mental states. Self-fulfilling Prophecy Self-fulfilling prophecy is engaging in behaviors that obtain results that confirm existing attitudes. Interesting Fact: Economic Recessions are self-fulfilling prophecies. Herd mentality is the tendency to adopt the opinions and follow the behaviors of the majority to feel safer and to avoid conflict.

Figurez-vous que vous avez du style! On pourrait croire que les figures de style sont l’apanage des grands auteurs et des professeurs de français qui prennent plaisir à tourmenter leurs étudiants... Pourtant, chacun de nous emploie quotidiennement plusieurs procédés stylistiques. Sans même y penser, nous agrémentons notre discours de métaphores, de métonymies ou d’ellipses. La plupart du temps, cependant, nous serions incapables de nommer ces figures. Difficile alors de différencier l’antiphrase de l’ironie, l’euphémisme de la litote, l’anacyclique du palindrome, ou la périphrase de la circonlocution. C’est pourquoi nous vous invitons à découvrir quelques procédés stylistiques... que vous connaissez peut-être déjà, sans le savoir. Lorsque vous connaîtrez mieux les figures de style, pourquoi ne pas tester vos connaissances et faire une grille de mots croisés sur le sujet?

Why We Believe Our Own Lies 0 Share Synopsis The power of cognitive dissonance in our daily lives. Leon Festinger was an American social psychologist, responsible for the development of the Theory of Cognitive Dissonance, which suggests that when people are persuaded to say things and to behave in ways that are inconsistent with their beliefs, an uncomfortable psychological tension is aroused. Festinger’s ground-breaking social psychological experiments provide a central insight into the stories we tell ourselves about why we think and behave the way we do. You are told the experiment is about how your expectations affect the actual experience of a task. Your first task is extremely boring. Then you are ushered through to another room where you are interviewed about the experiment you've just done. After the experiment you go and talk to your friend who was also doing the experiment. "No," you insist. The Power of Cognitive Dissonance What you've just experienced is the power of cognitive dissonance.
