A Simple Theory of Argument Schemes

While there has been in depth discussion of many particular argumentation schemes, some lament that there is little to no theory underpinning the notion of an argumentation scheme. Here I shall argue against the utility of argument schemes, at least as a fundamental part of a complete theory of arguments. I shall also present and defend a minimalist theory of their nature—a scheme is just a set of proposition expressions and propositional functions. While simple, the theory contravenes several typical desiderata of argumentation schemes such as (i) aiding in the identification of enthymemes and (ii) keeping arguments constrained to a manageable taxonomy. So much the worse for the desiderata. Instead, I shall recommend focusing less on schemes and more on the component propositional functions.

Reflections on Minimal Adversariality

Beginning with my 1999 account in The Philosophy of Argument, this essay explores views about adversariality in argument. Although my distinction between minimal and ancillary adversariality is widely accepted, there are flaws in my defense of the claim that all arguments exhibit minimal adversariality and in a lack of sensitivity to aspects of gender and culture. Further discussions of minimal adversariality, including those of Scott Aikin, John Casey, Katharina Stevens and Daniel Cohen, are discussed. The claim that all argument are adversarial in at least a minimal sense is defended due to its connection with arguers’ intent to support their conclusions.

The Distinction Between False Dilemma and False Disjunctive Syllogism

Since a clear account of the fallacy of false disjunctive syllogism is missing in the literature, the fallacy is defined and its three types are differentiated after some preliminaries. Section 4 further elaborates the differentia specifica for each of the three types by analyzing relevant argument criticism of each, as well as the related profiles of dialogue. After defining false disjunctive syllogisms, it becomes possible to distinguish between a false dilemma and a false disjunctive syllogism: section 5 analyzes their similarities (which explains why the fallacies are often confused with one another) and section 6 explains their differences.

On Appeals to Non-existent Authorities as Arguments from Analogy

Herein, I consider arguments resting on an appeal to a non-existent authority as a species of argument from authority, and ultimately show them to be reliant on arguments from analogy in their inferential force. Three sub-types of argument are discussed: from authorities as yet unborn, no longer living, or incapable of ever doing so. In each case it is shown that an element of arguing from analogy is required since there can be no direct evidence of any assertions of the source. In conclusion, it is suggested that such steps of analogy are employed frequently in traditional arguments from authority.

In Memoriam

Our beloved colleague, Charles Arthur Willard, has died at the age of 76. He will be remembered within the argumentation community not only as an influential theorist but also as one of the chief architects of an international and interdisciplinary field devoted to the study of argumentation.

Discovering Warrants in Political Argumentation

Philosophers deny a proposal for actions can be deduced from arguments for or against the proposal because they may be incompatible. Nevertheless, people in general, and politicians especially, make decisions and present arguments they believe are convincing. We studied politicians who made decisions in complex situations. They spoke about possible actions, their consequences, the probabilities of these consequences and their evaluations, but rarely indicated why their arguments led to their choice. We hypothesized implicit argumentation rules involved and checked whether they predicted those choices. We found seven implicit informal logic rules involved. We also found a random sample of people made the same choices based on the same arguments, suggesting basic warrants by which people argue about decisions.

Argumentative Bullshit

Harry Frankfurt characterised bullshit as assertions that are made without a concern for truth. Assertions, however, are not the only type of speech act that can be bullshit. Here, I propose the concept of argumentative bullshit and show how a speech acts account of bullshit assertions can be generalised to bullshit arguments. Argumentative bullshit, on this account, would be the production of an argument without a concern for the supporting relation between reasons and claim.

Inference Claims as Assertions

When a speaker states an argument in arguing—in its core sense—for the conclusion, the speaker asserts, as opposed to merely implies or implicates, the associated inference claim to the effect that the conclusion follows from the premises. In defense of this, I argue that how an inference claim is conveyed when stating an argument is constrained by constitutive and normative conditions for core cases of the speech of arguing for a conclusion. The speech act of assertion better reflects such conditions than does implication, conversational implicature, or conventional implicature.

Illocutionary Performance and Objective Assessment in the Speech Act of Arguing

This paper endorses a view of argumentation and arguments that relates both to a special type of speech action, namely, the performance of speech acts of arguing. Its aim is to advance an analysis of those acts that takes into account two kinds of norms related to their correct performance, namely, felicity conditions and objective requirements related to the “correspondence with the facts.” It assumes that the requirement that certain objective conditions be satisfied is among the set of felicity conditions of speech acts of arguing. Taking this into account helps clarify the position and role of warrants in the performance and assessment of these acts.
