Michael Almeida has recently tried to show that if S5 correctly represents metaphysical necessity, there can be no non-trivial evidence for or against the existence of the traditional God. Evidence would thus be irrelevant to the reasonability of traditional theistic belief. Almeida's argument has implications beyond its announced target: it amounts to a new argument for sweeping scepticism. Almeida's argument for the irrelevance of evidence to the existence of God would apply to any state of affairs that entails some metaphysical (...) necessity. In S5, every state of affairs entails some metaphysical necessity, so Almeida should conclude that non-trivial evidence for or against any state of affairs is impossible. I argue that the problem is not with S5 but with inadequately motivated assumptions about evidential support. Avoiding those assumptions disables the argument for sweeping scepticism and without foreclosing the possibility of non-trivial evidence for or against the existence of the traditional God. (shrink)

In the long history of moral theory, non-human animals—hereafter, just animals—have often been neglected entirely or have been relegated to some secondary status. Since its emergence in the early 19th century, utilitarianism has made a difference in that respect by focusing upon happiness or well-being (and their contraries) rather than upon the beings who suffer or enjoy. Inevitably, that has meant that human relations to and use of other animals have appeared in a different light. Some cases have seemed easy: (...) once admit that the interests of animals matter and there can be little hesitation in condemning their cruel treatment. Among the more difficult cases has been the bearing of utilitarianism upon the use of animals in various kinds of research where, though the animals might suffer, there were believed to be prospects of great human benefit and where no cruel or malicious motives need be involved. What I shall provide in the current paper is an extended discussion of the bearing of utilitarianism upon practices of animal research. Since such practices have attracted both utilitarian criticism and defense, this will require the examination of arguments on both sides, including consideration of the human benefits, the animal costs, and the ways in which the one can be weighed against the other.

Recent divine command theorists make a serious and impressive case that a sophisticated divine command theory has significant metaethical advantages and can adequately meet traditional objections, such as the Euthyphro problem. I survey the attempt sympathetically with a view to explaining how the divine command theory can deal with traditional objections while delivering on metaethical desiderata, such as providing an account of ethical objectivity. I argue, however, that to the extent that a divine command theory succeeds, an ideal observer theory (...) can do equally well. Once the divine command theory is rendered immune to Euthyphro-related objections, we will have all the machinery needed to show that an ideal observer theory can provide the same metaethical advantages, without supposing the existence of a divine commander. Other things being equal, ontological simplicity favors the ideal observer theory. (shrink)

Eudaemonism is the common structure of the family of theories in which the central moral conception is eudaemonia , understood as "living well" or "having a good life." In its best form, the virtues are understood as constitutive and therefore essential means to achieving or having such a life. What I seek to do is to lay the groundwork for an approach to eudaemonism grounded in practical reason, and especially in instrumental reasoning, rather than in natural teleology. In the first (...) chapter, I argue that an approach based in natural teleology will not work. In the second, the claims of decision theory to be an adequate formal representation of instrumental reasoning are examined and found wanting. In the third, I develop an account of ordinary instrumental reasoning. In the fourth, I discuss the structure of eudaemonism, with the aim of showing that there is an intelligible and attractive doctrine that can be disentangled from the natural teleology. In the fifth, I sketch an argument showing that instrumental reasoning, as explicated in the third chapter, can bear on the selection of final and ultimate ends, and that it is plausible that the instrumental approach to moral theory that I am urging yields conclusions with a eudaemonistic structure. I also indicate directions for further development and exploration. (shrink)

Regan appeals to the benefit of the doubt as a reason to include some animals within the scope of his arguments about the rights of animals. I think the informal appeal to the benefit of the doubt can be fleshed out and made more compelling. What I shall do differs from his project, however. It is narrower in scope, because I shall focus on a single issue, the dietary use of animals. On another dimension, though, I aim to do more. (...) Regan thinks that it is “not unreasonable” to extend the benefit of the doubt, and that it is better to do so. I shall be arguing that it is unreasonable not to do so. (shrink)

In _The Conscious Mind: In Search of a Fundamental Theory_, David Chalmers poses an interesting and powerful challenge to materialism or physicalism. Further, he goes a long way towards providing a proof by example that the rejection of materialism need not commit one to scientifically suspicious “ghost in the machine” doctrines, but can be wedded to a generally naturalistic perspective. As an (as yet) unpersuaded physicalist and functionalist, his case against physicalism seems an appropriate target for criticism. However, it would (...) be beyond the scope of the present paper—or anything of similar length—to attempt a full-scale reply. A full-scale reply could be executed in brief compass only if Chalmers were guilty of (and rested his case entirely upon) some relatively simple mistake. But he does not. If he is mistaken, the mistakes are more subtle and difficult to bring to light. Instead, I shall outline the essentials of his case against materialism, attempt to point to one problem that appears to infect his views and argue that, if his position is to be acceptable, he needs to deal with it more adequately than he has so far.

The cover illustration for Richard Joyce’s elegant and powerful recent work, The Evolution of Morality, is a reproduction of an oddly fascinating and disturbing sixteenth-century engraving, the Anatomia del corpo humano. One has to examine the image for a minute to realize that the standing human figure, stripped of skin, and with muscles, tendons and joints revealed, holds the anatomist’s knife in his left hand and that, with his right, he holds up the single piece of skin, from bearded face (...) to dangling extremities, that had once covered his body. This is the anatomist self-flayed, revealed to inspection by his own knife. A double worry is suggested: the body without the skin may have surprising, or disquieting, features. There is no assurance that what is revealed will accord with our preconceptions. Additionally, there is the thought that only the artist’s magic, freezing a moment in time, permits the body to maintain its integrity. In reality, the body of the self-flayer would collapse and die in short order. -/- Richard Joyce similarly undertakes to wield the analytic knife of science and philosophy to cut away the surface appearance of the moral sense and see what lies beneath. Again, what we find may be surprising or disquieting. Beneath the surface, we find the once-hidden articulation of the moral sensibility. We see its parts, how they are connected, how one links to another. And we may also suspect or fear that what remains cannot long stand inspection in such a state. It may be, indeed, that “we murder to dissect.” And if so, then like the self-flayer, we are ourselves the victims. (shrink)

Decision theorists generally object to “honoring sunk costs” – that is, treating the fact that some cost has been incurred in the past as a reason for action, apart from the consideration of expected consequences. This paper critiques the doctrine that sunk costs should never be honored on three levels. As background, the rationale for the doctrine is explained. Then it is shown that if it is always irrational to honor sunk costs, then other common and uncontroversial practices are also (...) irrational. Second, it is argued that there is no satisfactory way to make a distinction between the two kinds of cases. Third, a proposal is developed which would explain how it could be rational, under certain circumstances, to honor sunk costs. (shrink)

Certain apparently simple problems of coming to an agreement are surprisingly difficult to analyze in terms of individually rational behavior with a given set of preferences and beliefs. Though initially the solution appears obvious, the reasoning that would be needed to reach the solution on the part of a pair of rational individuals seems baroque and doubtful. This is used to suggest that a more fruitful tack is to analyze the situation in terms of a kind of joint or shared (...) intentionality. If that can be invoked, what appears simple in practice will turn out to be simple in theory as well. (shrink)
