Key components of argumentation

  • Understanding and identifying arguments, either explicit or implied, and the goals of the participants in the different types of dialogue.
  • Identifying the premises from which conclusions are derived
  • Establishing the "burden of proof" — determining who made the initial claim and is thus responsible for providing evidence why his/her position merits acceptance
  • For the one carrying the "burden of proof", the advocate, to marshal evidence
    Evidence
    Evidence in its broadest sense includes everything that is used to determine or demonstrate the truth of an assertion. Giving or procuring evidence is the process of using those things that are either presumed to be true, or were themselves proven via evidence, to demonstrate an assertion's truth...

     for his/her position in order to convince or force the opponent's acceptance. The method by which this is accomplished is producing valid, sound, and cogent arguments, devoid of weaknesses, and not easily attacked.
  • In a debate, fulfillment of the burden of proof creates a burden of rejoinder. One must try to identify faulty reasoning in the opponent’s argument, to attack the reasons/premises of the argument, to provide counterexamples if possible, to identify any logical fallacies, and to show why a valid conclusion cannot be derived from the reasons provided for his/her argument.

Internal structure of arguments

Typically an argument has an internal structure, comprising the following
  1. a set of assumptions or premises
  2. a method of reasoning or deduction and
  3. a conclusion or point.


An argument must have at least one premise and one conclusion.

Often classical logic is used as the method of reasoning so that the conclusion follows logically from the assumptions or support. One challenge is that if the set of assumptions is inconsistent then anything can follow logically from inconsistency. Therefore it is common to insist that the set of assumptions is consistent. It is also good practice to require the set of assumptions to be the minimal set, with respect to set inclusion, necessary to infer the consequent. Such arguments are called MINCON arguments, short for minimal consistent. Such argumentation has been applied to the fields of law and medicine. A second school of argumentation investigates abstract arguments, where 'argument' is considered a primitive term, so no internal structure of arguments is taken on account.

In its most common form, argumentation involves an individual and an interlocutor/or opponent engaged in dialogue, each contending differing positions and trying to persuade each other. Other types of dialogue in addition to persuasion are eristic

Conversational argumentation

The study of naturally-occurring conversation arose from the field of sociolinguistics. It is usually called conversational analysis. Inspired by ethnomethodology, it was developed in the late 1960s and early 1970s principally by the sociologist Harvey Sacks and, among others, his close associates Emanuel Schegloff and Gail Jefferson. Sacks died early in his career, but his work was championed by others in his field, and CA has now become an established force in sociology, anthropology, linguistics, speech-communication and psychology. It is particularly influential in interactional sociolinguistics

, discourse analysis and discursive psychology, as well as being a coherent discipline in its own right. Recently CA techniques of sequential analysis have been employed by phoneticians to explore the fine phonetic details of speech.

Empirical studies and theoretical formulations by Sally Jackson and Scott Jacobs, and several generations of their students, have described argumentation as a form of managing conversational disagreement within communication contexts and systems that naturally prefer agreement.

Mathematical argumentation

The basis of mathematical truth has been the subject of long debate. Frege in particular sought to demonstrate (see Gottlob Frege, The Foundations of Arithemetic, 1884, and Logicism in Philosophy of mathematics) that arithmetical truths can be derived from purely logical axioms and therefore are, in the end, logical truth

s. The project was developed by Russell and Whitehead in their Principia Mathematica. If an argument can be cast in the form of sentences in Symbolic Logic, then it can be tested by the application of accepted proof procedures. This has been carried out for Arithmetic using Peano axioms. Be that as it may, an argument in Mathematics, as in any other discipline, can be considered valid only if it can be shown that it cannot have true premises and a false conclusion.

Scientific argumentation

Perhaps the most radical statement of the social grounds of scientific knowledge appears in Alan G.Gross's The Rhetoric of Science (Cambridge: Harvard University Press, 1990). Gross holds that science is rhetorical "without remainder," meaning that scientific knowledge itself cannot be seen as an idealized ground of knowledge. Scientific knowledge is produced rhetorically, meaning that it has special epistemic authority only insofar as its communal methods of verification are trustworthy. This thinking represents an almost complete rejection of the foundationalism on which argumentation was first based.

Legal argumentation

Legal arguments are spoken presentations to a judge or appellate court by a lawyer, or parties when representing themselves of the legal reasons why they should prevail. Oral argument at the appellate level accompanies written briefs, which also advance the argument of each party in the legal dispute. A closing argument, or summation, is the concluding statement of each party's counsel reiterating the important arguments for the trier of fact, often the jury, in a court case. A closing argument occurs after the presentation of evidence.

Political argumentation

Political arguments are used by academics, media pundits, candidates for political office and government officials. Political arguments are also used by citizens in ordinary interactions to comment about and understand political events. The rationality of the public is a major question in this line of research. A robust political science research tradition seems to prove that the American public is largely irrational and ignorant of even the most basic knowledge of national or world affairs.

A central line of this way of thinking is that logic is contaminated by psychological variables such as "wishful thinking," in which subjects confound the likelihood of predictions with the desirability of the predictions. People hear what they want to hear and see what they expect to see. If planners want something to happen they see it as likely to happen. Thus planners ignore possible problems, as in the American experiment with prohibition. If they hope something will not happen, they see it as unlikely to happen.

For Toulmin, the term "field" designates discourses within which arguments and factual claims are grounded. For Willard, the term "field" is interchangeable with "community," "audience," or "readership." Along similar lines, G. Thomas Goodnight has studied "spheres" of argument and sparked a large literature created by younger scholars responding to or using his ideas. The general tenor of these field theories is that the premises of arguments take their meaning from social communities.

Field studies might focus on social movements, issue-centered publics (for instance, pro-life versus pro-choice in the abortion dispute), small activist groups, corporate public relations campaigns and issue management, scientific communities and disputes, political campaigns, and intellectual traditions. In the manner of a sociologist, ethnographer, anthropologist, participant-observer, and journalist, the field theorist gathers and reports on real-world human discourses, gathering case studies that might eventually be combined to produce high-order explanations of argumentation processes. This is not a quest for some master language or master theory covering all specifics of human activity. Field theorists are agnostic about the possibility of a single grand theory and skeptical about the usefulness of such a theory. Theirs is a more modest quest for "mid-range" theories that might permit generalizations about families of discourses.

Stephen E. Toulmin's Contributions

By far, the most influential theorist has been the late Stephen E. Toulmin, the Cambridge educated philosopher and student of Wittgenstein. What follows below is a sketch of his ideas.

An Alternative to Absolutism and Relativism

Toulmin has argued that absolutism (represented by theoretical or analytic arguments) has limited practical value. Absolutism is derived from Plato’s idealized formal logic, which advocates universal truth; thus absolutists believe that moral issues can be resolved by adhering to a standard set of moral principles, regardless of context. By contrast, Toulmin asserts that many of these so-called standard principles are irrelevant to real situations encountered by human beings in daily life.

To describe his vision of daily life, Toulmin introduced the concept of argument fields; in The Uses of Argument (1958), Toulmin states that some aspects of arguments vary from field to field, and are hence called “field-dependent,” while other aspects of argument are the same throughout all fields, and are hence called “field-invariant.” The flaw of absolutism, Toulmin believes, lies in its unawareness of the field-dependent aspect of argument; absolutism assumes that all aspects of argument are field invariant.

Toulmin’s theories resolve to avoid the defects of absolutism without resorting to relativism: relativism, Toulmin asserted, provides no basis for distinguishing between a moral or immoral argument. In Human Understanding (1972), Toulmin suggests that anthropologists have been tempted to side with relativists because they have noticed the influence of cultural variations on rational arguments; in other words, the anthropologist or relativist overemphasizes the importance of the “field-dependent” aspect of arguments, and becomes unaware of the “field-invariant” elements. In an attempt to provide solutions to the problems of absolutism and relativism, Toulmin attempts throughout his work to develop standards that are neither absolutist nor relativist for assessing the worth of ideas.

Toulmin believes that a good argument can succeed in providing good justification to a claim, which will stand up to criticism and earn a favourable verdict.

Components of argument

In The Uses of Argument (1958), Toulmin proposed a layout containing six interrelated components for analyzing arguments:
  1. Claim: Conclusions whose merit must be established. For example, if a person tries to convince a listener that he is a British citizen, the claim would be “I am a British citizen.” (1)
  2. Data: The facts we appeal to as a foundation for the claim. For example, the person introduced in 1 can support his claim with the supporting data “I was born in Bermuda.” (2)
  3. Warrant: The statement authorizing our movement from the data to the claim. In order to move from the data established in 2, “I was born in Bermuda,” to the claim in 1, “I am a British citizen,” the person must supply a warrant to bridge the gap between 1 & 2 with the statement “A man born in Bermuda will legally be a British Citizen.” (3)
  4. Backing: Credentials designed to certify the statement expressed in the warrant; backing must be introduced when the warrant itself is not convincing enough to the readers or the listeners. For example, if the listener does not deem the warrant in 3 as credible, the speaker will supply the legal provisions as backing statement to show that it is true that “A man born in Bermuda will legally be a British Citizen.”
  5. Rebuttal: Statements recognizing the restrictions to which the claim may legitimately be applied. The rebuttal is exemplified as follows, “A man born in Bermuda will legally be a British citizen, unless he has betrayed Britain and has become a spy of another country.”
  6. Qualifier: Words or phrases expressing the speaker’s degree of force or certainty concerning the claim. Such words or phrases include “possible,” “probably,” “impossible,” “certainly,” “presumably,” “as far as the evidence goes,” or “necessarily.” The claim “I am definitely a British citizen” has a greater degree of force than the claim “I am a British citizen, presumably.”


The first three elements “claim,” “data,” and “warrant” are considered as the essential components of practical arguments, while the second triad “qualifier,” “backing,” and “rebuttal” may not be needed in some arguments.

When first proposed, this layout of argumentation is based on legal arguments and intended to be used to analyze the rationality of arguments typically found in the courtroom; in fact, Toulmin did not realize that this layout would be applicable to the field of rhetoric

 and communication until his works were introduced to rhetoricians by Wayne Brockriede and Douglas Ehninger. Only after he published Introduction to Reasoning (1979) were the rhetorical applications of this layout mentioned in his works.

The Evolution of Knowledge

Toulmin's Human Understanding (1972) asserts that conceptual change is evolutionary. This book attacks Thomas Kuhn’s explanation of conceptual change in The Structure of Scientific Revolutions. Kuhn held that conceptual change is a revolutionary (as opposed to an evolutionary) process in which mutually exclusive paradigms compete to replace one another. Toulmin criticizes the relativist elements in Kuhn’s thesis, as he points out that the mutually exclusive paradigms provide no ground for comparison; in other words, Kuhn’s thesis has made the relativists’ error of overemphasizing the “field variant” while ignoring the “field invariant,” or commonality shared by all argumentation or scientific paradigms.

Toulmin proposes an evolutionary model of conceptual change comparable to Darwin’s model of biological evolution. On this reasoning, conceptual change involves innovation and selection. Innovation accounts for the appearance of conceptual variations, while selection accounts for the survival and perpetuation of the soundest conceptions. Innovation occurs when the professionals of a particular discipline come to view things differently from their predecessors; selection subjects the innovative concepts to a process of debate and inquiry in what Toulmin considers as a “forum of competitions.” The soundest concepts will survive the forum of competition as replacements or revisions of the traditional conceptions.

From the absolutists’ point of view, concepts are either valid or invalid regardless of contexts; from a relativists’ perspective, one concept is neither better nor worse than a rival concept from a different cultural context. From Toulmin’s perspective, the evaluation depends on a process of comparison, which determines whether or not one concept will provide improvement to our explanatory power more so than its rival concepts.

Rejection of Certainty

In Cosmopolis (1990), Toulmin traces the Quest for Certainty back to Descartes and Hobbes, and lauds Dewey, Wittgenstein, Heidegger and Rorty for abandoning that tradition.

Pragma-dialectics

Scholars at the University of Amsterdam in the Netherlands have pioneered a rigorous modern version of dialectic
Dialectic
Dialectic is a method of argument for resolving disagreement that has been central to Indic and European philosophy since antiquity. The word dialectic originated in Ancient Greece, and was made popular by Plato in the Socratic dialogues...

  under the name pragma-dialectics. The intuitive idea is to formulate clearcut rules that, if followed, will yield rational discussion and sound conclusions. Frans H. van Eemeren, the late Rob Grootendorst

, and many of their students have produced a large body of work expounding this idea.

The dialectical conception of reasonableness is given by ten rules for critical discussion, all being instrumental for achieving a resolution of the difference of opinion (from Van Eemeren, Grootendorst, & Snoeck Henkemans, 2002, p. 182-183). The theory postulates this as an ideal model, and not something one expects to find as an empirical fact. The model can however serve as an important heuristic and critical tool for testing how reality approximates this ideal and point to where discourse goes wrong, that is, when the rules are violated. Any such violation will constitute a fallacy. Albeit not primarily focused on fallacies, pragma-dialectics provides a systematic approach to deal with them in a coherent way.

Artificial intelligence

Efforts have been made within the field of artificial intelligence

Artificial intelligence is the intelligence of machines and the branch of computer science that aims to create it. AI textbooks define the field as "the study and design of intelligent agents" where an intelligent agent is a system that perceives its environment and takes actions that maximize its...

 to perform and analyze the act of argumentation with computers. Argumentation has been used to provide a proof-theoretic semantics for non-monotonic logic
Non-monotonic logic
A non-monotonic logic is a formal logic whose consequence relation is not monotonic. Most studied formal logics have a monotonic consequence relation, meaning that adding a formula to a theory never produces a reduction of its set of consequences. Intuitively, monotonicity indicates that learning a...

, starting with the influential work of Dung (1995). Computational argumentation systems have found particular application in domains where formal logic and classical decision theory are unable to capture the richness of reasoning, domains such as law and medicine. A comprehensive overview of this area can be found in a recent book edited by Iyad Rahwan and Guillermo R. Simari.

Within Computer Science, the ArgMAS workshop series (Argumentation in Multi-Agent Systems), the CMNA workshop series, and now the COMMA Conference, are regular annual events attracting participants from every continent. The journal Argument & Computation is dedicated to exploring the intersection between argumentation and computer science.
