    Reasonable Doubt: A Note on Neutral Illatives and Arguments
    Argumentation 13 (3): 243-250. 1999.
    George Bowles and Thomas Gilbert claim that illatives such as so, therefore, and hence convey the meaning that the premise confers upon the conclusion a probability greater than 1/2. This claim is false, for there are straightforward uses of these illatives that do not convey the meaning that the probability is greater than 1/2. In addition, because Bowles' and Gilbert's claim is false, a revision of their definition of argument is required

    Exemplification and Argument
    Canadian Journal of Philosophy 42 (3-4): 235-254. 2012.
    Suppose you doubt that rationally persuasive arguments can have just premises that are obviously false. But now consider:(X) Grass is red. Some arguments have merely obviously false premises.'Grass is red' is the only premise and is obviously false, so (X) should convince you that there are arguments with merely obviously false premises. On the face of it, there is nothing irrational about being so convinced by (X). But then (X) is a rationally persuasive argument with merely obviously false pre…Read more

    A useful time machine
    Philosophy 77 (2): 281-282. 2002.
    Robert Casati and Achille C. Varzi, argue that time machines would be useless or have no practical applications on the grounds that travelling to the past would involve doing what has already been done. I argue that the sense in which travelling to the past involves doing what has already been done fails to support the claim that time machines would have no practical applications.

    Why We Still Do Not Know What a “Real” Argument Is
    Informal Logic 34 (1): 62-76. 2014.
    In his recent paper, “What a Real Argument is”, Ben Hamby attempts to provide an adequate theoretical account of “real” arguments. In this paper I present and evaluate both Hamby’s motivation for distinguishing “real” from non-“real” arguments and his articulation of the distinction. I argue that neither is adequate to ground a theoretically significant class of “real” arguments, for the articulation fails to pick out a stable proper subclass of all arguments that is simultaneously both theoreti…Read more

    Cogency and the Validation of Induction
    Argumentation 18 (1): 25-41. 2004.
    I.T. Oakley claims that the cogency of invalid, but cogent, arguments is context independent. Robert Pargetter and John Bigelow claim that the apparent cogency of any cogent, but invalid, argument is to be explained by the existence of a corresponding valid argument. I argue that both claims are incorrect and provide my own account of the cogency of arguments

    David Hitchcock, in his recent “Informal Logic and the Concept of Argument”, defends a recursive definition of ‘argument.’ I present and discuss several problems that arise for his definition. I argue that refining Hitchcock’s definition in order to resolve these problems reveals a crucial, but minimally explicated, relation that was, at best, playing an obscured role in the original definition or, at worst, completely absent from the original definition.
