"This is an important book, and no one interested in issues which touch on the free will will want to ignore it."--Ethics. In this stimulating and thought-provoking book, the author defends the thesis that free will is incompatible with determinism. He disputes the view that determinism is necessary for moral responsbility. Finding no good reason for accepting determinism, but believing moral responsiblity to be indubitable, he concludes that determinism should be rejected.

Joseph Keim Campbell has recently criticized Peter van Inwagen's Third Argument against compatibilism for its reliance on the existence of a remote past. In response, Anthony Brueckner has offered a new version of the Third Argument showing that determinism and free will are incompatible for all times t relative to which there is a past . In this paper I argue that although Brueckner's retooled argument fails to prove anything in favour of incompatibilism, its conclusion can be exploited to provide (...) another version of van Inwagen's original argument that doesn't rely on the existence of past times, thus withstanding Campbell's criticism.

This book is an English version of a book published in 1984 in French, the aim of which was to give a reconstruction of Diodorus Cronus's Master Argument, together with a historical analysis of some of the central modal notions on which it draws. In preparing the English text, Vuillemin has made some changes to the logic of his reconstruction of Diodorus's Argument and added an epilogue. The Master Argument consisted of three premises: Every past truth is necessary, The impossible (...) does not follow from the possible, and Something is possible which neither is nor will be true. Diodorus claimed that these premises are inconsistent, and purported to derive the negation of the third premise, which is plausibly to be identified with the principle of plenitude, from the first two premises.

The Master Argument, recorded by Epictetus, indicates that Diodorus had deduced a contradiction from the conjoint assertion of three propositions. The Argument, which has to do with necessity and contingency and therefore with freedom, has attracted the attention of logicians above all. There have been many attempts at reconstructing it in logical terms, without excessive worry about historical plausibility and with the foregone conclusion that it was sophistic since it directly imperilled our common sense notion of freedom. This text takes (...) exception to recent tradition, translating the propositions into logical terms. The propositions figuring in The Master Argument are interpreted in terms of temporal modal logic where both the modalities and the statements they govern have chronological indices. This means that the force of the argument comes not from purely logical or modal considerations, but from our experience of time. (shrink)
