    Truthmakers and the disjunction thesis
    Mind 109 (432): 67-80. 2000.
    The correspondence theory of truth has experienced something of a revival recently in the form of the Truthmaker Axiom: whatever is true, something makes it true. We consider various postulates which have been proposed to characterize truthmaking, in particular, the Disjunction Thesis (DT), that whatever makes a disjunction true must make one or other disjunct true. In conjunction with certain other assumptions, DT leads to triviality. We show that there are elaborations of truthmaking on which …Read more

    Western Logic
    Journal of the Indian Council for Philosophical Research 27 (1): 13-45. 2010.
    The editors invited us to write a short paper that draws together the main themes of logic in the Western tradition from the Classical Greeks to the modern period.
