We discuss some recent work by Tim Maudlin concerning Black Hole Information Loss. We argue, contra Maudlin, that there is a paradox, in the straightforward sense that there are propositions that appear true, but which are incompatible with one another. We discuss the significance of the paradox and Maudlin's response to it.

We show a sense in which the spacetime property of effective completeness—a type of “local hole-freeness” or “local inextendibility”—is not stable.

Little is in print on the development in Britain of university disciplines including the academic study of education. This paper provides a historical narrative of the study of adolescence from the 1870 Education Act to the contemporary day. Adolescence textbooks are examined in the context of changes in the education system, such as the demand for secondary education and the expansion of teacher education. Changing emphases in adolescence research are traced through various publications to illustrate curriculum developments. The important contributions (...) of Dame Olive Wheeler, Professor W. D. Wall and other leading writers on adolescence are evaluated. It is clear that in over a century of national educational provision British teachers have never faced a great choice of adolescence texts and the paper concludes with some reflections on this observation.

This, the fifth volume to appear in the "authoritative" edition of The Works of William James, is the first that is not strictly based on a previously published work, although 11 of the 21 essays were included in Collected Essays and Reviews, edited in 1920 by Ralph Barton Perry, and 2 in Memories and Studies, edited in 1911 by Henry James, the philosopher’s son. The selection is based on subject matter, "philosophy in a narrower sense" than was customary for James, (...) and subsequent volumes will include parallel collections of "essays in psychology, in religion and morality, and in psychic research".

At once a distinguished mathematician and an important figure in the Vienna Circle, Hans Hahn conducted a seminar in 1924-25 on the Principia Mathematica to "a very large audience" of mathematicians and philosophers. Translated from the German and edited by Brian McGuinness, with a biographical introduction by Karl Menger, the present volume consists largely of papers in the philosophy of mathematics covering the years 1929-34. "Our adoption of Russell’s position," writes Hahn, "may cause some surprise in Germany where all ears (...) are tuned, to the controversy between... Hilbert and Brouwer." It turns out, however, that Wittgenstein has made the decisive move: mathematics consists of tautologies, Russell having "shown" how to get by without sets. (shrink)

In the paper I offer a brief sketch of one of the sources of utilitarianism. Our biological ancestry is a matter of fact that is not altered by the way we describe ourselves. With philosophical theories it is otherwise. Utilitarianism can be described in ways that make it look as if it is as old as moral philosophy – as J. S. Mill thought it was. For my historical purposes, it is more useful to have an account that brings out (...) what is specific about Benthamism and its descendants. Let us try to make do with the following. First, utilitarianism asserts that the fundamental requirement of morality is that we are to maximize good, for everyone and not just for the agent. This basic principle presupposes that it makes sense to think of aggregating goods to make a total, and of comparing amounts of good thus aggregated. Second, the good to be brought about is located in feelings of pleasure, and the evil to be avoided in feelings of pain. These feelings have inherent value or disvalue regardless of how they are caused to exist and regardless of their own consequences. Third, all moral principles can be derived from the requirement that good be maximized. The principles involved in evaluating agents as well as in giving moral direction to action are nothing but applications of the basic principle. (shrink)

J. B. Schneewind's "The Invention of Autonomy" has been hailed as a major interpretation of modern moral thought. Schneewind's narrative, however, elides several serious interpretive issues, particularly in the transition from late medieval to early modern thought. This results in potentially distorted accounts of Thomas Aquinas, Hugo Grotius, and G. W. Leibniz. Since these thinkers play a crucial role in Schneewind's argument, uncertainty over their work calls into question at least some of Schneewind's larger agenda for the history of ethics.

Reasoning under uncertainty, that is, making judgements with only partial knowledge, is a major theme in artificial intelligence. Professor Paris provides here an introduction to the mathematical foundations of the subject. It is suited for readers with some knowledge of undergraduate mathematics but is otherwise self-contained, collecting together the key results on the subject, and formalising within a unified framework the main contemporary approaches and assumptions. The author has concentrated on giving clear mathematical formulations, analyses, justifications and consequences of the (...) main theories about uncertain reasoning, so the book can serve as a textbook for beginners or as a starting point for further basic research into the subject. It will be welcomed by graduate students and research workers in logic, philosophy, and computer science as a textbook for beginners, a starting point for further basic research into the subject, and not least, an account of how mathematics and artificial intelligence can complement and enrich each other.
