B. H. Slater has argued that there cannot be any truly paraconsistent logics, because it's always more plausible to suppose whatever "negation" symbol is used in the language is not a real negation, than to accept the paraconsistent reading. In this paper I neither endorse nor dispute Slater's argument concerning negation; instead, my aim is to show that as an argument against paraconsistency, it misses (some of) the target. A important class of paraconsistent logics - the preservationist logics - are not subject to this objection. In addition I show that if we identify logics by means of consequence relations, at least one dialetheic logic can be reinterpreted in preservationist (non-dialetheic) terms. Thus the interest of paraconsistent consequence relations - even those that emerge from dialetheic approaches - does not depend on the tenability of dialetheism. Of course, if dialetheism is defensible, then paraconsistent logic will be required to cope with it. But the existence (and interest) of paraconsistent logics does not depend on a defense of dialetheism

Two aims are at work in James Brown'sSmoke and Mirrors:to defend realism against some of its recent detractors, and to expound his own programmatic commitment to a Platonic form of realism. I am sympathetic to his first goal, and dubious about the second, so, as Brown himself predicts, I am enthusiastic about the critical part of the book but critical of his Platonic project. But I will begin this review with a hearty recommendation.Smoke and Mirrorsis clear, articulate, perceptive, occasionally provocative, and a healthy antidote to the sceptical pessimism about science that one encounters so often today.

Whether we’re reading H.G. Wells, Robert Heinlein, Ray Bradbury, or Kurt Vonnegut, time travel is a wonderful narrative trick, freeing a story from the normal ‘one damn thing after another’ progression of time. But many philosophers claim it can never be more than that because backwards causation in general, and time travel in particular, are logically impossible.In this paper I examine one type of argument commonly given for this disappointing conclusion: the time travel paradoxes. Happily for science fiction fans, these arguments fall far short of showing what they are intended to show. Why they fail can be better understood in the light of an analogy between these arguments and some arguments libertarians offer against determinism.

Darwinian natural selection draws on Malthus’ harsh vision of human society to explain how organisms come to be adapted to their environments. Natural selection produces the appearance of teleology, but requires only efficient causal processes: undirected, heritable variation combined with effects of the variations on survival and reproduction. This paper draws a sharp distinction between the resulting form of backwards-directed teleology and the future-directed teleology we ascribe to intentional human activity. Rather than dismiss teleology as mere illusion, the paper concludes with an account of how future-directed teleology came to be a justifiable part of how we understand ourselves

The most pressing problems facing humanity today - over-population, energy shortages, climate change, soil erosion, species extinctions, the risk of epidemic disease, the threat of warfare that could destroy all the hard-won gains of civilization, and even the recent fibrillations of the stock market - are all ecological or have a large ecological component. in this volume philosophers turn their attention to understanding the science of ecology and its huge implications for the human project. To get the application of ecology to policy or other practical concerns right, humanity needs a clear and disinterested philosophical understanding of ecology which can help identify the practical lessons of science. Conversely, the urgent practical demands humanity faces today cannot help but direct scientific and philosophical investigation toward the basis of those ecological challenges that threaten human survival. This book will help to fuel the timely renaissance of interest in philosophy of ecology that is now occurring in the philosophical profession. Provides a bridge between philosophy and current scientific findings Covers theory and applications Encourages multi-disciplinary dialogue
