Frans Hendrik van Eemeren (born 7 April 1946, Helmond) is a Dutch scholar, professor in the Department of Speech Communication, Argumentation Theory and Rhetoric at the University of Amsterdam. [1] He is noted for his Pragma-dialectics theory, an argumentation theory which he developed with Rob Grootendorst from the early 1980s onwards. [2] He has published numerous books and papers, including Strategic Maneuvering in Argumentative Discourse.
Ad hominem, short for argumentum ad hominem, refers to several types of arguments, most of which are fallacious.
Dialectic, also known as the dialectical method, is a discourse between two or more people holding different points of view about a subject but wishing to establish the truth through reasoned argumentation. Dialectic resembles debate, but the concept excludes subjective elements such as emotional appeal and rhetoric. Dialectic may thus be contrasted with both the eristic, which refers to argument that aims to successfully dispute another's argument, and the didactic method, wherein one side of the conversation teaches the other. Dialectic is alternatively known as minor logic, as opposed to major logic or critique.
A fallacy is the use of invalid or otherwise faulty reasoning, or "wrong moves" in the construction of an argument which may appear stronger than it really is if the fallacy is not spotted. The term in the Western intellectual tradition was introduced in the Aristotelian De Sophisticis Elenchis.
Procatalepsis, also called prolepsis or prebuttal, is a figure of speech in which the speaker raises an objection to their own argument and then immediately answers it. By doing so, they hope to strengthen their argument by dealing with possible counter-arguments before their audience can raise them.
Argumentation theory, or argumentation, is the interdisciplinary study of how conclusions can be supported or undermined by premises through logical reasoning. With historical origins in logic, dialectic, and rhetoric, argumentation theory, includes the arts and sciences of civil debate, dialogue, conversation, and persuasion. It studies rules of inference, logic, and procedural rules in both artificial and real-world settings.
Pragma-dialectics, or pragma-dialectical theory, developed by Frans H. van Eemeren and Rob Grootendorst at the University of Amsterdam, is an argumentation theory that is used to analyze and evaluate argumentation in actual practice. Unlike strictly logical approaches, or purely communication approaches, pragma-dialectics was developed to study the entirety of an argumentation as a discourse activity. Thus, the pragma-dialectical theory views argumentation as a complex speech act that occurs as part of natural language activities and has specific communicative goals.
Douglas Neil Walton was a Canadian academic and author, known for his books and papers on argumentation, logical fallacies and informal logic. He was a Distinguished Research Fellow of the Centre for Research in Reasoning, Argumentation, and Rhetoric (CRRAR) at the University of Windsor, Ontario, Canada, and before that (2008–2014), he held the Assumption Chair of Argumentation Studies at the University of Windsor. Walton's work has been used to better prepare legal arguments and to help develop artificial intelligence.
Appeal to the stone, also known as argumentum ad lapidem, is a logical fallacy that dismisses an argument as untrue or absurd. The dismissal is made by stating or reiterating that the argument is absurd, without providing further argumentation. This theory is closely tied to proof by assertion due to the lack of evidence behind the statement and its attempt to persuade without providing any evidence.
Charles Arthur Willard is an American argumentation and rhetorical theorist. He is a retired Professor and University Scholar at the University of Louisville in Louisville, Kentucky, USA.
Sally Ann Jackson is an American scholar of argumentation, communication, and rhetoric. She is a professor of communication at the University of Illinois at Urbana-Champaign.
An argument is a statement or group of statements called premises intended to determine the degree of truth or acceptability of another statement called a conclusion. Arguments can be studied from three main perspectives: the logical, the dialectical and the rhetorical perspective.
Informal logic encompasses the principles of logic and logical thought outside of a formal setting. However, the precise definition of "informal logic" is a matter of some dispute. Ralph H. Johnson and J. Anthony Blair define informal logic as "a branch of logic whose task is to develop non-formal standards, criteria, procedures for the analysis, interpretation, evaluation, criticism and construction of argumentation." This definition reflects what had been implicit in their practice and what others were doing in their informal logic texts.
The burden of proof is the obligation on a party in a dispute to provide sufficient warrant for its position.
Rob Grootendorst was a Dutch communication and argumentation theory scholar. He was professor for Dutch speech communication at the University of Amsterdam. His contributions to the argumentation field include the co-foundation of the pragma-dialectic school in argumentation theory.
Appeal to accomplishment is a genetic fallacy wherein Person A challenges a thesis put forward by Person B because Person B has not accomplished similar feats or accomplished as many feats as Person C or Person A.
John Hayden Woods is a Canadian logician and philosopher. He currently holds the position of Director of the Abductive Systems Group at the University of British Columbia (UBC) and is The UBC Honorary Professor of Logic. He is also affiliated with the Group on Logic, Information and Computation within the Department of Informatics at King's College London where he has held the Charles S. Peirce Visiting Professorship of Logic position since 2001.
Howard Kahane was an American professor of philosophy at Bernard M. Baruch College in New York City. He was noted for promoting a popular, and non-mathematical, approach to logic, now known as informal logic. His best known publication in that area is his textbook Logic and Contemporary Rhetoric: The Use of Reason in Everyday Life, now at the 12th edition, published in 2014.
Harald R. Wohlrapp is a German philosopher. His main focus is argumentation theory.
Formal scientists have attempted to combine logic and dialectic through formalisation. These attempts include pre-formal and partially formal treatises on argument and dialectic, systems based on defeasible reasoning, and systems based on game semantics and dialogical logic.
In argumentation theory, an argumentation scheme or argument scheme is a template that represents a common type of argument used in ordinary conversation. Many different argumentation schemes have been identified. Each one has a name and presents a type of connection between premises and a conclusion in an argument, and this connection is expressed as a rule of inference. Argumentation schemes can include inferences based on different types of reasoning—deductive, inductive, abductive, probabilistic, etc.
