We give a tensor formulation of synchronization transformations within special relativity in order to bridge the gap between some philosophical discussions (e.g., by Grünbaum and Winnie) and the analyses given by physicists (e.g., Møller). As an application, we discuss a physical interpretation of the duality between covariant and contravariant indices in the tensor formulation.

This is a welcome reprint of a book that continues to grow in importance.

The question of political sovereignty must at all times be of acute academic interest, since it is practically impossible to say anything about the state without implying something about sovereignty, or vice versa. Political theory has very generally found this conception central to its inquiry; but in recent years the notion has been thrown into sharp relief by political events . In Fascism and Nazism the doctrine of state sovereignty is “made flesh” in startlingly substantial forms. These modern incarnations of (...) Leviathan , and their threat to much which has come to be deeply valued, give unprecedented importance to an age-long discussion. Political theory is not to-day, if it has ever seemed, a simply academic issue, or an “arm-chair” branch of philosophy. Not all of those who carry through revolutions, who build barricades and defend them with their lives, have a clear philosophical theory of the state; but powerful beliefs and motives they certainly have; and it daily becomes more manifest that unless the world is content to allow its political future to be determined more and more by obscure visceral impulses or crude economic motives a more intense effort to achieve and to apply true beliefs in the political field is imperative.

Two attitudes are possible: one, that the world is an absolute jungle and that the exercise of coercive power by rulers is only a manifestation of this; and the other, that it is both necessary and right that there should be this exercise of power, that through it the world is much less of a jungle than it could possibly be without it, so that one should in principle be glad of the existence of such power, and only take exception (...) to its unjust exercise.

The author presents and defends three theses: (1) "the first is that it is not profitable for us at present to do moral philosophy; that should be laid aside at any rate until we have an adequate philosophy of psychology." (2) "the second is that the concepts of obligation, And duty... And of what is morally right and wrong, And of the moral sense of 'ought', Ought to be jettisoned if this is psychologically possible...." (3) "the third thesis is that (...) the differences between the well-Known english writers on moral philosophy from sidgwick to the present day are of little importance." (staff). (shrink)

In 2005 St Andrews Studies published a volume of essays by Anscombe entitled Human Life, Action and Ethics, followed in 2008 by a second with the title Faith in a Hard Ground. Both books were highly praised. This third volume brings essays on the thought of historical philosophers in which Anscombe engages directly with their ideas and arguments. Many are published here for the first time and the collection provides further testimony to Anscombe's insight and intellectual imagination.

John Buridan was a fourteenth-century philosopher who enjoyed an enormous reputation for about two hundred years, was then totally neglected, and is now being 'rediscovered' through his relevance to contemporary work in philosophical logic. The final chapter of Buridan's Sophismata deals with problems about self-reference, and in particular with the semantic paradoxes. He offers his own distinctive solution to the well-known 'Liar Paradox' and introduces a number of other paradoxes that will be unfamiliar to most logicians. Buridan also moves on (...) from these problems to more general questions about the nature of propositions, the criteria of their truth and falsity and the concepts of validity and knowledge. This edition of that chapter is intended to make Buridan's ideas and arguments accessible to a wider range of readers. The volume should interest many philosophers, linguists and logicians, who are increasingly finding in medieval work striking anticipations of their own concerns. (shrink)
