    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

    What exactly is logical pluralism?

    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.

    Contextualists with regard to knowledge argue that the truth of the claim 'x knows that P' is contextually dependent. In doing so, they attempt to articulate the nature of the contextual dependence. Since part of making knowledge claims involves the adequate justification of beliefs, I shall explore whether any epistemic contextualist theories can be modified or adapted to provide an account of the context-dependence of justificatory strength for arguments. I shall conclude that the prospects ar…Read more

    Banana peels and time travel
    Dialectica 61 (4). 2007.
    A world in which time travel into the past occurred would seem like a most strange world. Nicholas Smith, however, in his ‘Bananas Enough for Time Travel’, argues that time travel is not so strange as we think. In particular, he argues against what he views as the main reason time travel worlds seem so strange – the claim that time travel entails unusual numbers of coincidences. I shall argue that Smith's argument for rejecting the claim is inadequate. Hence, the debate over the consequences of …Read more
