A couple of decades after becoming a major area of both public and philosophical concern, animal ethics continues its inroads into main- stream consciousness. Increasingly, philosophers, ethicists, professionals who use animals, and the broader public confront specific ethical issues regarding human use of animals as well as more fundamental questions about animals’ moral status. A parallel, related development is the explo- sion of interest in animals’ mental lives, as seen in exciting new work in cognitive ethology and in the plethora (...) of movies, television commercials, and popular books featuring apparently intelligent animals. -/- As we approach the turn of the twenty-first century, philosophical animal ethics is an area of both increasing diversity and unrealized poten- tial – a thesis supported by this essay as a whole. Following up on an earlier philosophical review of animal ethics (but without that review’s focus on animal research), the present article provides an updated narrative – one that offers some perspective on where we have been, a more detailed account of where we are, and a projection of where we might go. Each of the three major sections offers material that one is unlikely to find in other reviews of animal ethics: the first by viewing familiar territory in a different light (advancing the thesis that the utility-versus-rights debate in animal ethics is much less important than is generally thought); the second by reviewing major recent works that are not very well-known (at least to nonspecialists); and the third by identifying important issues that have been largely neglected.

The Units of Selection debate is a dispute about the causes of population change. I argue that it is generated by a particular `dynamical'' interpretation of natural selection theory, according to which natural selection causes differential survival and reproduction of individuals and natural selection explanations cite these causes. I argue that the dynamical interpretation is mistaken and offer in outline an alternative, `statistical'' interpretation, according to which natural selection theory is a fancy kind of `bookkeeping''. It explains by citing the (...) statistical structure of a population and not by citing the causes of survival and reproduction. From the perspective of the statistical interpretation there is no substantive Units of Selection issue. (shrink)

This paper argues that the foundations of our knowledge are the bed-rock certainties of ordinary life, what may be called the Moorean truths. Beyond that are the well-established results within the empirical sciences, and whatever has been proved in the rational sciences of mathematics and logic. Otherwise there is only belief, which may be more or less rational. A moral drawn from this is that dogmatism should be moderated on all sides.

Recently, certain philosophers of mathematics (Fallis [1997]; Womack and Farach [(1997]) have argued that there are no epistemic considerations that should stop mathematicians from using probabilistic methods to establish that mathematical propositions are true. However, mathematicians clearly should not use methods that are unreliable. Unfortunately, due to the fact that randomized algorithms are not really random in practice, there is reason to doubt their reliability. In this paper, I analyze the prospects for establishing that randomized algorithms are reliable. I end (...) by arguing that it would be inconsistent for mathematicians to suspend judgement on the truth of mathematical propositions on the basis of worries about the reliability of randomized algorithms.

We investigate the semantics of the logical systems obtained by introducing the modalities and into the family of substructural implication logics (including relevant, linear and intuitionistic implication). Then, in the spirit of the LDS (Labelled Deductive Systems) methodology, we "import" this semantics into the classical proof system KE. This leads to the formulation of a uniform labelled refutation system for the new logics which is a natural extension of a system for substructural implication developed by the first two authors in (...) a previous paper.

What has come to be known as “a priori physicalism” is the thesis, roughly, that the non-physical truths in the actual world can be deduced a priori from a complete physical description of the actual world. To many contemporary philosophers, a priori physicalism seems extremely implausible. In this paper I distinguish two kinds of a priori physicalism. One sort – strict a priori physicalism – I reject as both unmotivated and implausible. The other sort – liberal a priori physicalism – (...) I argue is both motivated and plausible. This variety of a priori physicalism insists that the necessitation of non-physical truths by the physical facts must be underwritten in a certain fashion by a priori knowledge, but the a priori knowledge need not amount to a simple deduction of the non-physical truths from a complete physical description of the world. Further, this sort of liberal a priori physicalism has the advantage that it offers hope for a genuinely satisfying account of how the physical facts manage to necessitate the facts about phenomenal consciousness – thereby in effect solving the “hard problem” of consciousness. The first half of the paper sets out the motivation for liberal a priori physicalism and its superiority to the strict version; the second half presents one strategy available to the liberal a priori physicalist for showing how consciousness can be accommodated in a purely physical world.

In his 1987 book _Conditionals, Frank Jackson presents an argument to the effect that the indicative conditionals of natural language have the same truth conditions as the material conditional of truth-functional logic. This Jackson refers to as the "paradox of indicative conditionals." I offer a solution to this paradox by arguing that some conditionals that appear to be in the indicative mood are actually subjunctives, to which the paradox does not apply. I support this proposed solution with some historical observations (...) on the evolution of the English verb phrase. (edited). (shrink)

We report the results of a randomized trial to assess the impact of an innovative ethics curriculum on the knowledge and confidence of 85 medical house officers in a university hospital programme, as well as their responses to a simulated clinical case. Twenty-five per cent of the house officers received a lecture series, 25 per cent received lectures and case conferences, with an ethicist in attendance, and 50 per cent served as controls. A post-intervention questionnaire was administered. Knowledge scores did (...) not differ among the groups. Confidence regarding ethical issues was significantly greater in the aggregate intervention group compared to the control group. Confidence regarding procedural issues related to ethics was significantly higher for the EI group than for the controls. Responses to a simulated case showed that significantly fewer house officers in the EI group would intubate a patient for whom such therapy would be futile. We conclude that ethics education can have an impact on house officers' confidence and their responses to a simulated case, and that the EI was more effective than the LI. Such results have implications regarding the implementation of ethics education during residency. (shrink)

The role of the environment in producing the correct classical limit in the Bohm interpretation of quantum mechanics is investigated, in the context of a model of quantum Brownian motion. One of the effects of the interaction is to produce a rapid approximate diagonalisation of the reduced density matrix in the position representation. This effect is, by itself, insufficient to produce generically quasi-classical behaviour of the Bohmian trajectory. However, it is shown that, if the system particle is initially in an (...) approximate energy eigenstate, then there is a tendency for the Bohmian trajectory to become approximately classical on a longer time-scale. The relationship between this phenomenon and the behaviour of the Wigner function post-decoherence is discussed. (shrink)

Critical factors that appear to encourage vocal development in humans are altriciality and long immaturity. Hominid infants appear to have evolved a specific tendency to use elaborate vocalization as a means of soliciting long-term investment from caregivers. The development of such vocal capacity provides necessary infrastructure for language development across human life history.

In 1987 Jerrold Levinson wrote, in a review of George Dickie's _The Art Circle_, that in reading it he felt 'caught in a kind of aesthetic time warp'. I had the same feeling, and indeed have the same feeling when I read papers published since on Dickie's theory. A recent criticism in this journal by Oswald Hanfling is a case in point. To be fair, Hanfling explicit states that he is discussing the 1974 version of the theory rather than Dickie's (...) current views. However, this weakens the paper as a contribution to the current debate. Dickie no longer advocates the 1974 theory, as opposed to the 1984 version. Hanfling also directs most of his argument against the second disjunct of that definition, largely ignoring the first. furthermore, following recent work on the theory by others, Dickie's theory has become a more protean creature than Hanfling suppose. Criticism are rarely decisive; what works against one version of the theory is ineffective against another. In this paper I will argue that the theory as standardly conceived can be broken down into two logically independent parts. Once this is done, the objections current in the literature are not decisive. I will then attempt to evaluate what I take to be the improved version. (shrink)

In his 'The Disorder of Things' John Dupré presents an objection to reductionism which I call the 'anti-essentialist objection': it is that reductionism requires essentialism, and essentialism is false. I unpack the objection and assess its cogency. Once the objection is clearly in view, it is likely to appeal to those who think conceptual analysis a bankrupt project. I offer on behalf of the reductionist two strategies for responding, one which seeks to rehabilitate conceptual analysis and one (more concessive) which (...) avoids commitment to any such analysis.

What has been the fate of Christianity since Nietzsche's famous announcement of the "death of God"? What is the possibility of religion, specifically Christianity, thriving in our postmodern era? In this provocative new book, Gianni Vattimo, leading Italian philosopher, politician, and framer of the European constitution, addresses these critical questions. When Vattimo was asked by a former teacher if he still believed in God, his reply was, "Well, I believe that I believe." This paradoxical declaration of faith serves as the (...) foundation for a brilliant exposition on Christianity in the new millennium -- an age characterized by a deep uncertainty of opinion -- and a personal account of how Vattimo himself recovered his faith through Nietzsche and Heidegger. He first argues that secularization is in fact the fulfillment of the central Christian message, and prepares us for a new mode of Christianity. He then explains that Nietzsche's thesis concerns only the "moral god" and leaves room for the emergence of "new gods." Third, Vattimo claims that the postmodern condition of fragmentation, anti-Eurocentrism, and postcolonialism can be usefully understood in light of Joachim of Fiore's thesis concerning the "Spiritual Age" of history. Finally, Vattimo argues for the idea of "weak thought." Because philosophy in the postmetaphysical age can only acknowledge that "all is interpretation," that the "real" is always relative and not the hard and fast "truth" we once thought it to be, contemporary thought must recognize itself and its claims as "weak" as opposed to "strong" foundationalist claims of the metaphysical past. Vattimo concludes that these factors make it possible for religion and God to become a serious topic for philosophy again, and that philosophy should now formally engage religion. (shrink)

In this paper I discuss the topics of mechanism and algorithmicity. I emphasise that a characterisation of algorithmicity such as the Turing machine is iterative; and I argue that if the human mind can solve problems that no Turing machine can, the mind must depend on some non-iterative principle — in fact, Cantor's second principle of generation, a principle of the actual infinite rather than the potential infinite of Turing machines. But as there has been theorisation that all physical systems (...) can be represented by Turing machines, I investigate claims that seem to contradict this: specifically, claims that there are noncomputable phenomena. One conclusion I reach is that if it is believed that the human mind is more than a Turing machine, a belief in a kind of Cartesian dualist gulf between the mental and the physical is concomitant.

A method for constructing continua of logics squeezed between some intermediate predicate logics, developed by Suzuki [8], is modified and applied to intervals of the form [L, L+ ¬¬S], where Lis a predicate logic, Sis a closed predicate formula. This solves one of the problems from Suzuki's paper.

In «The Normativity of Meaning», Eric Gampel argues that the capacity to justify a linguistic usage is essential to meaning and suggests that this fact entails that naturalistic theories of meaning must take a non-reductive form if they are to be viable. I will argue that reductive and non-reductive naturalisms stand or fall together in the face of Gampel's argument that meaning plays an essential justificatory role. I will further argue that, if they fall, the lesson to be learned is (...) not that we should avoid reductionism, but rather, that we should steer clear of physicalism in our meaning theory; if Gampel's argument is cogent, any theory of meaning will have to make reference to at least some abstract objects.

The Kenya-born philosopher Henry Odera Oruka (1944 - 1995) persistently, and consistently, made proposals for a different moral approach to addressing, and possibly solving, some of the root causes of human conflicts across the world. I will call it “taking suffering seriously” as the basis of his idea of a global-level collective justice which, for him, raised the idea of the ethics of care to the level of global justice. I propose in this paper to show that this concern can (...) be found to be pervasive in Oruka’s works, connecting many of his well known positions as well as less known ones, and to discuss its philosophical merits.
