. Although it was poorly received in England and satirized as "Toulmin's anti-logic book" by Toulmin's fellow philosophers at Leeds, the book was applauded by the rhetoricians in the United States, where Toulmin served as a visiting professor at New York, Stanford, and Columbia Universities in 1959. While in the States, Wayne Brockriede and Douglas Ehninger introduced Toulmin's work to communication scholars, as they recognized that his work provided a good structural model useful for the analysis and criticism of rhetorical arguments. In 1960, Toulmin returned to London to hold the position of director of the Unit for History of Ideas of the Nuffield Foundation. In 1965, Toulmin returned to the United States, where he held positions at various universities. In 1967, Toulmin served as literary executor for close friend N.R. Hanson, helping in the posthumous publication of several volumes. While at the

Meta-philosophy


Objection to absolutism and relativism

Throughout many of his works, Toulmin pointed out that
absolutism Absolutism may refer to: Government * Absolute monarchy, in which a monarch rules free of laws or legally organized opposition * Absolutism (European history), period c. 1610 – c. 1789 in Europe ** Enlightened absolutism, influenced by the En ...

's idealized formal logic, which advocates universal truth; accordingly, absolutists believe that moral issues can be resolved by adhering to a standard set of moral principles, regardless of context. By contrast, Toulmin contends that many of these so-called standard principles are irrelevant to real situations encountered by human beings in daily life. To develop his contention, Toulmin introduced the concept of argument fields. In ''The Uses of Argument'' (1958), Toulmin claims 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. 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 neglects or is unaware of the "field-invariant" elements. In order 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. In ''Cosmopolis'' (1990), he traces philosophers' "quest for certainty" back to

Humanizing modernity

In ''Cosmopolis'' Toulmin seeks the origins of the modern emphasis on universality (philosophers' "quest for certainty"), and criticizes both modern science and philosophers for having ignored practical issues in preference for abstract and theoretical issues. The pursuit of

consisting of four returns: a return to oral communication and discourse, a plea which has been rejected by modern philosophers, whose scholarly focus is on the printed page; a return to the particular or individual cases that deal with practical moral issues occurring in daily life (as opposed to theoretical principles that have limited practicality); a return to the local, or to concrete cultural and historical contexts; and, finally, a return to the timely, from timeless problems to things whose rational significance depends on the time lines of our solutions. He follows up on this critique in ''Return to Reason'' (2001), where he seeks to illuminate the ills that, in his view, universalism has caused in the social sphere, discussing, among other things, the discrepancy between mainstream ethical theory and real-life ethical quandaries.


Argumentation


The Toulmin model of argument

Arguing that
absolutism Absolutism may refer to: Government * Absolute monarchy, in which a monarch rules free of laws or legally organized opposition * Absolutism (European history), period c. 1610 – c. 1789 in Europe ** Enlightened absolutism, influenced by the En ...
lacks practical value, Toulmin aimed to develop a different type of argument, called practical arguments (also known as substantial arguments). In contrast to absolutists' theoretical arguments, Toulmin's practical argument is intended to focus on the justificatory function of argumentation, as opposed to the inferential function of theoretical arguments. Whereas theoretical arguments make inferences based on a set of principles to arrive at a claim, practical arguments first find a claim of interest, and then provide justification for it. Toulmin believed that reasoning is less an activity of inference, involving the discovering of new ideas, and more a process of testing and sifting already existing ideas—an act achievable through the process of justification. Toulmin believed that for a good argument to succeed, it needs to provide good justification for a claim. This, he believed, will ensure it stands up to criticism and earns a favourable verdict. In ''The Uses of Argument'' (1958), Toulmin proposed a layout containing six interrelated components for analyzing arguments: ;Claim (Conclusion): A conclusion whose merit must be established. In argumentative essays, it may be called the thesis. 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). ;Ground (Fact, Evidence, Data): A fact one appeals 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). ;Warrant: A statement authorizing movement from the ground to the claim. In order to move from the ground 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 and 2 with the statement "A man born in Bermuda will legally be a British citizen" (3). ;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: "I trained as a
barrister A barrister is a type of lawyer in common law jurisdictions. Barristers mostly specialise in courtroom advocacy and litigation. Their tasks include taking cases in superior courts and tribunals, drafting legal pleadings, researching law and givin ...
in London, specialising in citizenship, so I know that a man born in Bermuda will legally be a British citizen". ;Rebuttal (Reservation): Statements recognizing the restrictions which may legitimately be applied to the claim. It 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 for another country". ;Qualifier: Words or phrases expressing the speaker's degree of force or certainty concerning the claim. Such words or phrases include "probably", "possible", "impossible", "certainly", "presumably", "as far as the evidence goes", and "necessarily". The claim "I am definitely a British citizen" has a greater degree of force than the claim "I am a British citizen, presumably". (See also: Defeasible reasoning.) The first three elements, ''claim'', ''ground'', 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 Toulmin first proposed it, this layout of argumentation was based on legal arguments and intended to be used to analyze the rationality of arguments typically found in the courtroom. Toulmin did not realize that this layout could be applicable to the field of rhetoric and communication until his works were introduced to rhetoricians by Wayne Brockriede and Douglas Ehninger. Their ''Decision by Debate'' (1963) streamlined Toulmin's terminology and broadly introduced his model to the field of debate. Only after Toulmin published ''Introduction to Reasoning'' (1979) were the rhetorical applications of this layout mentioned in his works. One criticism of the Toulmin model is that it does not fully consider the use of ''questions'' in argumentation. The Toulmin model assumes that an argument starts with a fact or claim and ends with a conclusion, but ignores an argument's underlying questions. In the example "Harry was born in Bermuda, so Harry must be a British subject", the question "Is Harry a British subject?" is ignored, which also neglects to analyze why particular questions are asked and others are not. (See Issue mapping for an example of an argument-mapping method that emphasizes questions.) Toulmin's argument model has inspired research on, for example, goal structuring notation (GSN), widely used for developing

s, and argument maps and associated software.


Ethics


Good reasons approach

In ''Reason in Ethics'' (1950), his doctoral dissertation, Toulmin sets out a Good Reasons approach of ethics, and criticizes what he considers to be the subjectivism and emotivism of philosophers such as A. J. Ayer because, in his view, they fail to do justice to ethical reasoning.


The revival of casuistry

By reviving casuistry (also known as case ethics), Toulmin sought to find the middle ground between the extremes of
absolutism Absolutism may refer to: Government * Absolute monarchy, in which a monarch rules free of laws or legally organized opposition * Absolutism (European history), period c. 1610 – c. 1789 in Europe ** Enlightened absolutism, influenced by the En ...
and relativism. Casuistry was practiced widely during the

period, in ''The Abuse of Casuistry: A History of Moral Reasoning'' (1988), Toulmin collaborated with Albert R. Jonsen to demonstrate the effectiveness of casuistry in practical argumentation during the Middle Ages and the Renaissance, effectively reviving it as a permissible method of argument. Casuistry employs absolutist principles, called "type cases" or "

cases", without resorting to absolutism. It uses the standard principles (for example,

) as referential markers in moral arguments. An individual case is then compared and contrasted with the type case. Given an individual case that is completely identical to the type case, moral judgments can be made immediately using the standard moral principles advocated in the type case. If the individual case differs from the type case, the differences will be critically assessed in order to arrive at a rational claim. Through the procedure of casuistry, Toulmin and Jonsen identified three problematic situations in moral reasoning: first, the type case fits the individual case only ambiguously; second, two type cases apply to the same individual case in conflicting ways; third, an unprecedented individual case occurs, which cannot be compared or contrasted to any type case. Through the use of casuistry, Toulmin demonstrated and reinforced his previous emphasis on the significance of comparison to moral arguments, a significance not addressed in theories of absolutism or relativism.


Philosophy of science


The evolutionary model

process. In this book, Toulmin attacks Thomas Kuhn's account of conceptual change in his seminal work '' The Structure of Scientific Revolutions'' (1962). Kuhn believed that conceptual change is a revolutionary process (as opposed to an evolutionary process), during which mutually exclusive paradigms compete to replace one another. Toulmin criticized the relativist elements in Kuhn's thesis, arguing that mutually exclusive paradigms provide no ground for comparison, and that Kuhn made the relativists' error of overemphasizing the "field variant" while ignoring the "field invariant" or commonality shared by all argumentation or scientific paradigms. In contrast to Kuhn's

model of conceptual change comparable to Darwin's model of biological evolution. Toulmin states that conceptual change involves the process of 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 Moral absolutism is an ethical view that some (potentially all) actions are intrinsically right or wrong. Stealing, for instance, might be considered to be always immoral, even if done for the well-being of others (e.g., stealing food to feed a ...
' point of view, concepts are either valid or invalid regardless of contexts. From the 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 improve explanatory power more than its rival concepts.
