Support functions $s(h,e)=p(h\backslash e)-p(h)$ are widely used in discussion of explanation, causality and, recently, in connection with the possibility or otherwise of probabilistic induction. With this latter application in view, a rather complete analysis of the variety of support functions, their interrelationships and their "non-deductive" and "inductive" components is presented. With the restriction to two propositions, three variable probabilities are enough to discuss such problems. The analysis is illustrated by graphs, a Venn diagram and by using the Laplace Rule of (...) Succession as an illustrative example. It is concluded that within this framework one cannot prove or disprove the possibility of probabilistic induction. (shrink)

Two problems have long been confused with each other: the gravitational redshift as discussed by the equivalence principle; and the Doppler shift observed by a detector which moves with constant proper acceleration away from a stationary source. We here distinguish these two problems and give for the first time a solution of the former which is ‘exact’ within the context of the equivalence principle in a sense discussed in the paper. The equivalence principle leads to transformations between flat spacetimes. These (...) are analyzed, and a generalized Lorentz transformation is proposed which covers transformations from inertial to uniformly accelerated frames of reference. (shrink)

It is suggested that anoversight occurred in classical mechanics when time-derivatives of observables were treated on the same footing as the undifferentiated observables. Removal of this oversight points in the direction of quantum mechanics. Additional light is thrown on uncertainty relations and on quantum mechanics, as a possible form of a subtle statistical mechanics, by the formulation of aclassical uncertainty relation for a very simple model. The existence of universal motion,i.e., of zero-point energy, is lastly made plausible in terms of (...) a gravitational constant which is time-dependent. By these three considerations an attempt is made to link classical and quantum mechanics together more firmly, thus giving a better understanding of the latter. (shrink)

«The chapter on «Times's Arrows» is a confusing blend of speculation and possibly wrong ideas.»From a review of M Gell‐Mann's «The Quark and the Jaguar» by P W Anderson in Physics World, August 1994.

It is shown, assuming the linear case of Schinzel's Hypothesis, that the first-order theory of the structure $\langle \omega; +, P\rangle$ , where P is the set of primes, is undecidable and, in fact, that multiplication of natural numbers is first-order definable in this structure. In the other direction, it is shown, from the same hypothesis, that the monadic second-order theory of $\langle\omega; S, P\rangle$ is decidable, where S is the successor function. The latter result is proved using a general (...) result of A. L. Semenov on decidability of monadic theories, and a proof of Semenov's result is presented. (shrink)

"No other work treating Indian philosophy on a comparable scale contains the illuminating comparisons between doctrines of Indian schools and the thought of Western philosophy ranging from Plato to Sartre and Wittgenstein...It will, moreover, contribute to the understanding of Western philosophy by Indian thinkers and vice versa...Raju has an intimate acquaintance with a remarkable range of Western thinkers and this distinguishes his work from most of what has gone before...Raju, moreover, is himself a critical thinker and consequently, although he has (...) written a history, he treats the ideas and doctrines in a philosophical mode and his assessments of positions are often original and illuminating." -- John E. Smith, Clark Professor of Philosophy, Yale University "Purpose: To deal with Indian philosophy in a fashion reflecting the way the best German historians of philosophy deal with Western philosophy...The book is remarkable for its comprehensiveness in combination with extensive critical discussions...Raju's book...is more critical than Radhakrishnan's and more philosophical than Dasgupta's. Radhakrishnan's comments are far less philosophically sophisticated and interesting than Raju's....a monument to a senior Indian philosopher's lifelong study and thoughtful critical consideration of the great classical systems of his tradition." -- Karl H. Potter, Professor of Philosophy, University of Washington "Raju's credentials are impeccable. He is one of the few scholars in the world who could presume to write a major work on Indian thought. Accordingly, his knowledge of the Indian schools is accurate and impressive. To the extent that one of his intentions is to cast those schools in terms which make them more intelligible to western readers, his work measures up very well." -- Harold H. Oliver, Professor of Philosophy, Boston University. (shrink)

The Euthyphro might well be given to undergraduates to read early in their philosophical training. The arguments are apparently simple, but some of them, as I shall show, lead naturally on to thorny problems of modern philosophy. Another benefit that could be gained from reading the Euthyphro is that the reader may learn to be forewarned against some common fallacies and debating tricks in moral disputes.

Those philosophers who gave a negative answer to all four questions were called "eel-wrigglers" by the Buddhists. It was impossible to fix their position either for approval or for rejection. They would criticize any view, positive or negative, but would not themselves hold any. And it was difficult for a serious person to enter into any controversy with them.

It is fortunate for my purposes that English has the two words ‘almighty’ and ‘omnipotent’, and that apart from any stipulation by me the words have rather different associations and suggestions. ‘Almighty’ is the familiar word that comes in the creeds of the Church; ‘omnipotent’ is at home rather in formal theological discussions and controversies, e.g. about miracles and about the problem of evil. ‘Almighty’ derives by way of Latin ‘omnipotens’ from the Greek word ‘pantokratōr’; and both this Greek word, (...) like the more classical ‘pankratēs’, and ‘almighty’ itself suggest God's having power over all things. On the other hand the English word ‘omnipotent’ would ordinarily be taken to imply ability to do everything; the Latin word ‘omnipotens’ also predominantly has this meaning in Scholastic writers, even though in origin it is a Latinization of ‘pantocratōr’. So there already is a tendency to distinguish the two words; and in this paper I shall make the distinction a strict one. I shall use the word ‘almighty’ to express God's power over all things, and I shall take ‘omnipotence’ to mean ability to do everything. (shrink)

It may be seen from the foregoing that Pauline's existence is multiply jeopardized; or rather, that my right to use 'Pauline' as a name, the way I said I was going to, is very doubtful, for I agree with Parmenides that one cannot name what is not there to be named. The words I have used to describe Pauline's various perils are full of what Ryle aptly called "systematically misleading expressions"; but we need not worry about that for the moment-enough (...) for now if the words succeed in bringing the various cases before our minds--and we can tidy up our language as we come to see things more clearly.

The title I have chosen naturally suggests the question: What are you saying omnipotence is irrelevant to? I reply: This doctrine is irrelevant to worthwhile discussion of the problem of evil. By this phrase I understand: the problem how the existence of a God with the attributes traditionally ascribed to him in Christian belief can be reconciled with the occurrence of the sorts of evil that we find in the world.
