We show, that given two fundamental theses of Kripke, no statement of the form ‘‘a=b’ is necessarily true’, is true, if ‘a’ and ‘b’ are distinct rigid designators.

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 his argument on this implication rather than on what we call the force of truth. (shrink)

We suggest that the classical version of the consequence argument contending that freedom and determinism are incompatible subtly misstates the core intuition, which is that if a true conditional and a true antecedent are jointly beyond our control, then so is the consequent. We show however that the improved version no less than the classical implies fatalism.Interestingly, the reasoning, that yields fatalism, undermines a direct argument for the soundness of the improved version. But if fatalism is sound, then trivially, so (...) is the new version. We shall however argue that the new version cannot be sound. A weaker version is proved sound but its domain of application excludes the most intuitive paradigm cases.We share van Inwagen's thought that his “‘N’is a very interesting operator” and debate some of its features. Our results, if sound, suggest that the consequence argument in terms of ensurable and non‐ensurable truth may not be the right way to approach issues of determinism and freedom. (shrink)

We show that the thesis that identity is necessary is equivalent to the thesis that everything is necessarily what it is. Hence the challenges facing either, faces them both.

Alex Blum ABSTRACT: We argue that the part of the future which is up to us is in principle unknowable. Download PDF.

We contend that since what is true cannot be false, foreknowledge is transparently incompatible with free will. We argue that what is crucial to the conflict is the role of truth in foreknowledge and that the identity of the one who foreknows is irrelevant.

We argue that the part of the future which is up to us is in principle unknowable.

We discuss some of the consequences of the belief that while God keeps His promises under every possible circumstance He can nevertheless break them. One interesting consequence is that no proof is possible for the proposition that God keeps His promises. We also point out that for this believer, necessity and possibility cannot be reformulated as truth in all and some possible worlds, respectively.

In 'The Structure of Science' Nagel contends that a deductive explanation of the occurrence of an individual event must contain at least one instantial statement as a premiss (Nagel, 1961, p. 31). I shall defend a version of his contention.

It is argued that the constraints placed on the non-law premisses of a D–N explanation are irrelevant to their function and will not salvage the deductive requirement from triviality.

We show that Kripke’s argument for the necessity of identity statements relating objects a and b by their rigid designators demands an additional significant premise.

We content that a very seductive argument for theological fatalism fails. In the course of our discussion we point out that theological fatalism is incompatible with the existence of a being who is omnipotent, omniscient and infallible. We end by suggesting 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.
