According to the prevailing sentiment, changing the past is logically impossible. The prevailing sentiment is wrong. In this paper, I argue that the claim that changing the past entails a contradiction ultimately rests upon an empirical assumption, and so the conclusion that changing the past is logically impossible is to be resisted. I then present and discuss a model of time which drops the empirical assumption and coherently models changing the past. Finally, I defend the model, and changing the past, (...) against objections.

These documents, published here for the first time, present the Treasury's counter-arguments during the period when Keynes was developing the ideas that led to the Keynesian revolution in economic policy. Keynes spent much effort trying to persuade the Treasury to adopt policies designed to raise employment and stabilise prices, and to create an international monetary system that would favour these objectives. His arguments are set out fully in the Royal Economic Society's 30-volume set of The Collected Writings of John Maynard (...) Keynes. In contrast, the views of his Treasury critics have hitherto been much less accessible.Economists and historians have tended to assume that Keynes was right and the Treasury was wrong; this volume shows that the Treasury anticipated the political problems that would be encountered in putting Keynes's ideas into practice. Much of what Keynes published was deliberately polemical: he believed that words should be 'a little wild', for they were 'the assault of thought on the unthinking'. Treasury officials were by no means as unthinking as Keynes tended to portray them, and they had a coherent and intellectually respectable understanding of public finance. Ministers in the inter-war period and early in the Second World War were sensitive to the use that political opponents might make of Keynes's arguments; officials had to provide counter-arguments, and in doing so they revealed much about their views on economics and public finance. Once Keynes became an adviser to the Chancellor of the Exchequer in 1940, the debate became internal to the Treasury, but officials continued to subject Keynes's ideas to critical analysis.The documents in this volume show Treasury responses to Keynes on a range of issues crucial to understanding the period and the context of the Keynesian revolution in public policy. The topics covered include: the return to the gold standard; the use of public expenditure to cure unemployment in the inter-war period; how to avoid inflation in the war; planning for the post-war international economy; and the 1944 white paper on employment policy. This edition is an essential tool for the study of a formative period of British history and a great intellectual debate. (shrink)

David Hitchcock, in his recent “Informal Logic and the Concept of Argument”, defends a recursive definition of ‘argument.’ I present and discuss several problems that arise for his definition. I argue that refining Hitchcock’s definition in order to resolve these problems reveals a crucial, but minimally explicated, relation that was, at best, playing an obscured role in the original definition or, at worst, completely absent from the original definition.

In his recent paper, “What a Real Argument is”, Ben Hamby attempts to provide an adequate theoretical account of “real” arguments. In this paper I present and evaluate both Hamby’s motivation for distinguishing “real” from non-“real” arguments and his articulation of the distinction. I argue that neither is adequate to ground a theoretically significant class of “real” arguments, for the articulation fails to pick out a stable proper subclass of all arguments that is simultaneously both theoretically relevant and a proper (...) subclass of all arguments.

Articles on Indic philosophy and religion.

Numerous informal logi- cians and argumentation theorists restrict their theorizing to what they call “real” arguments. But is there a clear distinction to be made between “real” and “non-real” arguments? Here I explore four possible accounts of the alleged distinction and argue that none can serve the theoretical uses to which the distinction is most often put. Résumé: Plusieurs logiciens construction formels et théoriciens de l’argument- ation limitent leur non de théories à ce qu’ils appellent des arguments « authentiques ». (...) Mais y-a- t’il une distinction claire entre des arguments« authentiques » et « inau- thentiques » ? Ici j’explore quatre descriptions possibles de cette préten- due distinction et je soutiens qu’- aucune ne répond aux besoins théori- ques auxquels elles sont censées ré- pondre. (shrink)

Quantum mechanics, which describes the behavior of subatomic particles, seems to challenge common sense. Waves behave like particles; particles behave like waves. You can tell where a particle is, but not how fast it is moving--or vice versa. An electron faced with two tiny holes will travel through both at the same time, rather than one or the other. And then there is the enigma of creation ex nihilo, in which small particles appear with their so-called antiparticles, only to disappear (...) the next instant in a tiny puff of energy. Since its inception, physicists and philosophers have struggled to work out the meaning of quantum mechanics. Some, like Niels Bohr, have responded to quantum mechanics' mysteries by replacing notions of position and velocity with probabilities. Others, like Einstein and Penrose, have disagreed and think that the entire puzzle reflects not a fundamental principle of nature but our own ignorance of basic scientific processes. Sneaking a Look at God's Cards offers the general reader a deep and real understanding of the problems inherent to the interpretation of quantum mechanics, from its inception to the present. The book presents a balanced overview of current debates and explores how the theory of quantum mechanics plays itself out in the real world. Written from the perspective of a leading European physicist, the book looks extensively at ideas from both sides of the Atlantic and also considers what philosophers have contributed to the scientific discussion of this field. Sneaking a Look at God's Cards sets out what we know about the endlessly fascinating quantum world, how we came to this understanding, where we disagree, and where we are heading in our quest to comprehend the seemingly incomprehensible.

We analyse a recent paper in which an alleged devastating criticism of the so called GRW proposal to account for the objectification of the properties of macroscopic systems has been presented and we show that the author has not taken into account the precise implications of the GRW theory. This fact makes his conclusions basically wrong. We also perform a survey of measurement theory aimed to focus better on the physical and the conceptual aspects of the so-called macro-objectification problem.

The Platonic Commentators.—After Cicero the Academy is no more than a few names to us for nearly five centuries. The nearest that we get to contact with it in this period is in the writings of Plutarch. He was himself a student there, and was well read in the books of Plato and the commentaries thereon.
