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.

In April 1939, G. E. Moore read a paper to the Cambridge University Moral Science Club entitled ‘Certainty’. In it, amongst other things, Moore made the claims that: the phrase ‘it is certain’ could be used with sense-experience-statements, such as ‘I have a pain’, to make statements such as ‘It is certain that I have a pain’; and that sense-experience-statements can be said to be certain in the same sense as some material-thing-statements can be — namely in the sense that (...) they can be safely counted on. When Moore later read his paper to Wittgenstein, Wittgenstein took violent exception to it, and the two entered into a heated exchange. The only known notes of this exchange are a previously unpublished verbatim record of part of it, taken by Norman Malcolm. This paper is an edition of Malcolm’s notes. These notes are valuable for both philosophical and scholarly reasons. They give us a glimpse of a sustained exchange between Wittgenstein and a real-life interlocutor; they contain a defence by Wittgenstein of the idea that a word’s use can illuminate its meaning; and they provide evidence of Wittgenstein’s philosophical engagement with the topic of certainty, and with Moore’s thought on it, long before he began to write the notes which make up On Certainty, in 1949.

G.E. Moore, more than either Bertrand Russell or Ludwig Wittgenstein, was chiefly responsible for the rise of the analytic method in twentieth-century philosophy. This selection of his writings shows Moore at his very best. The classic essays are crucial to major philosophical debates that still resonate today. Amongst those included are: * A Defense of Common Sense * Certainty * Sense-Data * External and Internal Relations * Hume's Theory Explained * Is Existence a Predicate? * Proof of an External World (...) In addition, this collection also contains the key early papers in which Moore signals his break with idealism, and three important previously unpublished papers from his later work which illustrate his relationship with Wittgenstein.

_Zettel, _ an en face bilingual edition, collects fragments from Wittgenstein's work between 1929 and 1948 on issues of the mind, mathematics, and language.

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.

The following suggestions for the interpretation of Parmenides and Melissus can be grouped for convenience about one problem. This is the problem whether, as Aristotle thought and as most commentators still assume, Parmenides wrote his poem in the broad tradition of Ionian and Italian cosmology. The details of Aristotle's interpretation have been challenged over and again, but those who agree with his general assumptions take comfort from some or all of the following major arguments. First, the cosmogony which formed the (...) last part of Parmenides' poem is expressly claimed by the goddess who expounds it to have some measure of truth or reliability in its own right, and indeed the very greatest measure possible for such an attempt. Second, the earlier arguments of the goddess prepare the ground for such a cosmogony in two ways. For in the first place these arguments themselves start from assumptions derived from earlier cosmologists, and are concerned merely to work out the implications of this traditional material. And, in the second place, they end by establishing the existence of a spherical universe: the framework of the physical world can be secured by logic even if the subsequent introduction of sensible qualities or ‘powers’ into this world marks some decline in logical rigour.

This book was first published in 1991. The study of ancient science and its relations with Greek philosophy has made a significant and growing contribution to our understanding of ancient thought and civilisation. This collection of articles on Greek science contains fifteen of the most important papers published by G. E. R. Lloyd in this area since 1961, together with three newer articles. The topics range over all areas and periods of Greek science, from the earliest Presocratic philosophers to Ptolemy (...) and Galen. In each case the article is preceded by an introduction that assesses scholarly debate on the topic since the original publication. Professor Lloyd also suggests modifications and developments to his own position in the light of those debates and his own further research. (shrink)

Originally published in 1965. This is a textbook of modern deductive logic, designed for beginners but leading further into the heart of the subject than most other books of the kind. The fields covered are the Propositional Calculus, the more elementary parts of the Predicate Calculus, and Syllogistic Logic treated from a modern point of view. In each of the systems discussed the main emphases are on Decision Procedures and Axiomatisation, and the material is presented with as much formal rigour (...) as is compatible with clarity of exposition. The techniques used are not only described but given a theoretical justification. Proofs of Consistency, Completeness and Independence are set out in detail. The fundamental characteristics of the various systems studies, and their relations to each other are established by meta-logical proofs, which are used freely in all sections of the book. Exercises are appended to most of the chapters, and answers are provided. (shrink)

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)

This book challenges several widespread views concerning Aristotle's methods and practices of scientific and philosophical research. Taking central topics in psychology, zoology, astronomy and politics, Professor Lloyd explores generally unrecognised tensions between Aristotle's deeply held a priori convictions and his remarkable empirical honesty in the face of complexities in the data or perceived difficult or exceptional cases. The picture that emerges of Aristotle's actual engagement in scientific research and of his own reflections on that research is substantially more complex than (...) is usually allowed. (shrink)

Written over the last 18 months of his life and inspired by his interest in G. E. Moore's defence of common sense, this much discussed volume collects Wittgenstein's reflections on knowledge and certainty, on what it is to know a proposition for sure.

These notes of G. E. Moore's lectures for the three terms of 1934-1935 were compiled by Alice Ambrose, then Student of Newnham College, and Margaret Macdonald, then Fellow of Girton College. The lectures cover a wealth of interrelated topics, and provide instances of the analyses which made Moore «the father of the analytic school.» Since his analyses of such concepts as material objects, sense data, and truth rest on the ordinary use of expressions for these concepts, «ordinary language» philosophers found (...) in him their champion. Moore examines the views of Broad, Russell, F. P. Ramsey, W. E. Johnson, and John Wisdom. (shrink)

In this thesis I argue for the following theory: constitutive Russellian phenomenal bonding panpsychism. To do so I do three main things: 1) I argue for Russellian panpsychism. 2) I argue for phenomenal bonding panpsychism. 3) I defend the resultant phenomenal bonding panpsychist model. The importance of arguing for such a theory is that if it can be made to be viable, then it is proposed to be the most promising theory of the place of consciousness within nature. This is (...) because constitutive Russellian panpsychism has all the theoretical virtues of physicalism and dualism but does not face the problems they do. The combination problem, however, is the most significant problem for the Russellian panpsychist, and, hence, in order to show the viability of the theory I address this problem. Moreover, I present a novel ”mereological argument’ for panpsychism which makes it necessary that the Russellian panpsychist addresses the combination problem. The focus of this thesis is therefore addressing this problem. I argue that the combination problem can indeed be solved. To do so I argue for the phenomenal bonding solution proposed by Goff. I argue that this solution works and that we can form a positive concept of the phenomenal bonding relation. This forces the panpsychist to make sense of how experiencing subjects can be proper parts of other experiencing subjects. I then argue that this can indeed be made sense of and show that we can indeed be composite subjects made of other subjects. To show that we can be subjects made up of other subjects I defend this proposal from various objections from throughout the literature. All these objections can be responded to by the constitutive Russellian phenomenal bonding panpsychist. Ultimately this leaves us with a novel and interesting account of what conscious subjects are, and what the material world is: they are both composite entities made wholly of conscious matter.

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

Some statements couched in the present tense have no reference to time. They are, if you like, grammatically tensed but logically tenseless. Mathematical statements such as ‘twice two is four’ or ‘there is a prime number between 125 and 128’ are of this sort. So is the statement I have just made. To ask in good faith whether there is still the prime number there used to be between 125 and 128 would be to show that one did not understand (...) the use of such statements, and so would any attempt to answer the question. It is tempting to take another step and talk of such timeless statements as statements about timeless entities. If the number 4 neither continues nor ceases to be twice two this is, surely, because the number 4 has no history of any kind, not even the being a day older today than yesterday. Other timeless statements might shake our confidence in this inference: ‘clocks are devices for measuring time’ is a timeless statement, but it is not about a class of timeless clocks. But, given a preoccupation with a favoured set of examples and a stage of thought at which men did not distinguish the properties of statements from the properties of the things they are about, we can expect timeless entities to appear as the natural proxies of timeless statements.

It is now nearly axiomatic among Platonic scholars that the Timaeus and its unfinished sequel the Critias belong to the last stage of Plato's writings. The Laws is generally held to be wholly or partly a later production. So, by many, is the Philebus, but that is all. Perhaps the privileged status of the Timaeus in the Middle Ages helped to fix the conviction that it embodies Plato's maturest theories.

pain' and ┌I think that p┐ express the pain and the thought that p, themselves. The book is most impressive. It is packed with careful argument, and addresses a remarkable range of important issues about the mind. I have very much enjoyed studying it.
