Argumentation theory

philosophy religion Maturity 9-11 Next article →

Argumentation theory is an interdisciplinary study of how conclusions are supported or undermined by premises. Through logical reasoning, this field examines how people use premises to reach a specific point. It encompasses the arts and sciences of civil debate, dialogue, and persuasion. Scholars in this field study rules of inference and procedural rules. These rules apply to both artificial settings and real-world human interactions. Argumentation is a daily occurrence in public debate, science, and law.

It provides the tools to express and rationally manage disagreements.

An argument possesses a specific internal structure. It typically consists of a set of assumptions or premises. These premises are connected by a method of reasoning, such as deduction. The process results in a conclusion or a main point. An argument usually has one or more premises but only one conclusion. For an argument to be effective, the premises should be consistent. This means they do not contradict one another. Some scholars seek MINCON arguments, which are minimal consistent arguments. These are the smallest set of assumptions necessary to reach a conclusion.

There are many distinct types of dialogue used in argumentation. Persuasion dialogue aims to resolve conflicting points of view. Negotiation focuses on resolving conflicts of interest through cooperation and dealmaking. Inquiry is used to resolve general ignorance by growing knowledge. Deliberation helps groups reach a decision when action is required. Information seeking reduces ignorance by requesting data from a knowledgeable party. Some dialogue is didactic, which is used specifically for teaching. In contrast, eristic dialogue is a form of social debate where victory is the primary goal.

Argumentation theory has deep historical roots in philosophy. It originated from foundationalism, a theory of knowledge known as epistemology. Early scholars sought the grounds for claims in logic and factual laws. The dialectical method was made famous by Plato. He used the character Socrates to question others through dialogue. Over time, scholars rejected the systematic philosophy of Aristotle and the idealism of Kant. They moved away from the idea that premises get soundness from formal systems. In 1958, Chaïm Perelman and Lucie Olbrechts-Tyteca introduced la nouvelle rhetorique. This approach described argumentation that was not limited to formal rules of inference.

In the mid-20th century, the field expanded toward everyday human interaction. Karl R. Wallace wrote a seminal essay in 1963 about "good reasons." This led to the study of "marketplace argumentation." This term describes the ordinary arguments made by ordinary people. Ray Lynn Anderson and C. David Mortensen published a key essay on this in 1967. This shift connected argumentation to the sociology of knowledge. Some thinkers also linked it to the pragmatism of John Dewey and Richard Rorty. Rorty referred to this shift as the "linguistic turn." These developments allowed for "non-philosophical" theories to grow in many fields.

Argumentation is vital in specialized professional fields. In law, judges and prosecutors use it to test the validity of evidence. In mathematics, scholars like Gottlob Frege sought to derive truths from logical axioms. Mathematicians use symbolic logic and proof procedures to test arguments. In science, some scholars like Alan G. Gross suggest that scientific knowledge is produced rhetorically. This means science relies on trustworthy communal methods of verification. Interpretive argumentation is also used in the humanities. This process helps people explore or resolve meanings in ambiguous texts. It is used in areas like literary theory, linguistics, and aesthetics.

Sociologists also study how argumentation functions in natural conversation. This is often called conversation analysis, or CA. It was developed in the late 1960s and early 1970s. Harvey Sacks was a principal developer of this field. He worked alongside Emanuel Schegloff and Gail Jefferson. CA is now an established force in anthropology, linguistics, and psychology. It helps researchers understand how people manage disagreements during communication. This study shows how argumentation is woven into the very fabric of human social life.
