51The Force of TruthPhilosophical Investigations 34 (4): 393-395. 2011.The theme of the paper is that what is true cannot be false and conversely. This position was anticipated by Aristotle in De Interpretatione and by G. H. von Wright. The latter calls it “a truth of the logic of relative modalities.”Aristotle has been taken to task by Susan Haack and others for arguing fallaciously from the Principle of Bivalence, that every statement is either true or false, to fatalism. The implication holds, but we show that it is unreasonable to assume that Aristotle grounded…Read more

We suggest that ‘possible’ formalized as ‘◊’ is to be understood as ‘can or could have been’ and not simply as ‘can’. The argument we discuss conflates the two. We end by rounding out, hope-fully, some left over corners of serious concern to the theist
