In "personal and impersonal identity" ("mind", 1988) timothy sprigge discusses reasons for a general suspicion of trans-temporal identity, and rejects what he says are the usual grounds given against the suspicion, providing instead his own reasons for rejecting it. he concludes that trans-temporal identity, including personal identity, is as genuine a case of identity as what he considers to be the paradigmatic case of identity. in this brief note i take issue with some of the basic elements of sprigge's argument

This is an introductory talk on why I am not a consequentialist. I am not going to go into the details of consequentialist theory, or to compare and contrast different versions of consequentialism. Nor am I going to present all the reasons I am not a consequentialist, let alone all the reasons why you should not be one. All I want to do is focus on some key problems that in my view, and the view of many others, make consequentialism a totally unacceptable moral theory – a theory about what is right, what is good, or obligatory, or forbidden, or permissible, or praiseworthy. So let me begin by giving a basic definition of consequentialism, one all supporters of the view can agree on. Consequentialism is the theory that the fundamental aim of morality is to maximize value. Now I was tempted to say ‘sole aim’, but some consequentialists will disagree with that. They might hold, for instance, that one of the aims of morality is to abide by certain rules, or to cultivate certain virtues. But for them, what gives obedience to a rule or the cultivation of a virtue its point is that, ultimately, such behaviour maximizes value. So although maximizing value might not be the sole aim of morality – the sole answer to the question ‘What should I do to be good?’ and similar questions – still it is the fundamental aim of morality, and all other kinds of decision, action, and so on, derive their justification by reference to it. For my purposes, then, the difference between ‘sole’ and ‘fundamental’ is merely terminological. Now the first thing that might occur to someone is a pair of simple questions. Why should anyone believe that the fundamental aim of morality is to maximize value? What intuitive force does the idea even have in the first place? These are good questions. I was a consequentialist once, and I don’t think I ever posed them to myself. I just took it as understood that since so many philosophers were consequentialists, and since so many of my fellow students were as well, then even if it were ultimately shown not to be true, the maximization thought (as I will call it) was at least the obvious place to start when one did ethics..

Over the course of a career that has spanned more than fifty years, philosopher Fred Sommers has taken on the monumental task of reviving the development of Aristotelian (syllogistic) logic after it was supplanted by the predicate logic of Gottlob Frege and Bertrand Russell. The enormousness of Sommers's undertaking can be gauged by the fact that most philosophers had come to believe - as David S. Oderberg writes in his preface - that "Aristotelian logic was good but is now as good as dead." A revival of traditional syllogistic logic would involve not only its restatement but its refashioning into a system that could rival the elegance and deductive power of predicate logic. Building on work by medieval scholastic logicians, Leibniz, and nineteenth-century algebraic logicians, Sommers accomplished this renovation and rehabilitation of syllogistic logic with his magnum opus The Logic of Natural Language, published in 1982. In The Old New Logic, essays by a diverse group of contributors show how widely influential Sommers's work has been-not only in logic, but in category theory and other areas. Scholars in psychology, linguistics, and computer science join philosophers and logicians in discussing aspects of Sommers's contributions to philosophy. Sommers himself provides an intellectual autobiography at the beginning and in the final chapter offers comments on the contributions. This collection should help bring to Sommers's work the attention it deserves from the wider philosophical and intellectual community.

Distinguished metaphysicians examine issues central to the high-profile debate between philosophers over how to classify the natural world, and discuss issues in applied ontology such as the classification of diseases. Leading metaphysicians explore fundamental questions related to the classification and structure of the natural world An essential commentary on issues at the heart of the contemporary debate between philosophy and science Interweaves discussion of overarching themes with detailed material on applied ontology

You might be wondering what an article 0n animal rights is doing in a journal devoted to the defence of human life. It turns out that the connections are closer than you may think. Grasping them is crucial to a proper understanding of just why innocent human life must be defended, of why the killing of even the tiniest, youngest member of the human species is an unspeakable crime. For it is by analysing the issue of whether animals have rights that we come to see the core differences between humans and other animals1—-the differences in the nature of humans and animals that mean..
