In this article I show that the argument in John Harris's famous "Survival Lottery" paper cannot be right. Even if we grant Harris's assumptions—of the justifiability of such a lottery, the correctness of maximizing consequentialism, the indistinguishability between killing and letting die, the practical and political feasibility of such a scheme—the argument still will not yield the conclusion that Harris wants. On his own terms, the medically needy should be less favored (and more vulnerable to being killed), than Harris suggests

There is a world-wide shortage of kidneys for transplantation. Many people will have to endure lengthy and unpleasant dialysis treatments, or die before an organ becomes available. Given this chronic shortage, some doctors and health economists have proposed offering financial incentives to potential donors to increase the supply of transplantable organs. In this paper, I explore objections to the practice of buying and selling organs from the point of view 1) justice, 2) beneficence and 3) Commodification. Regarding objection to the Commodification of transplant organs, I examine a number of possible justifications of this objection but conclude that each of these would, if true, rule out the donation of transplant organs or the selling of numerous accepted commodities, or is implausible for some other reason.

Analytic philosophers often claim that the giving and criticizing of deductive arguments is the main or only business of philosophy. I argue that this is mistaken and show analytic philosophers also use formal schemas, distinctions, examples, and analogies so as to make some aspect of reality manifest. That is, some analytic philosophers sometimes simply try to ‘tell it like it is’. This ‘method of descriptive manifestation’ is less commonly recognized than it should be given its divergence from the self-image of analytic philosophy

I begin by asking the meta-epistemological question, 'What is justification?', analogous to the meta-ethical question, 'What is rightness?' I introduce the possibility of non-cognitivist, naturalist, non-naturalist, and eliminativist answers in meta-epistemology,corresponding to those in meta-ethics. I devote special attention to the naturalistic hypothesis that epistemic justification is identical to probability, showing its antecedent plausibility. I argue that despite this plausibility, justification cannot be identical with probability, under the standard interpretation of the probability calculus, for the simple reason that justification can increase indefinitely but probability cannot. I then propose an alternative model for prima facie justification, based on an analogy with Ross's account of prima facie obligation, arguing that this model illuminates the differences between justification and probability and, given the plausible assumption of epistemic pluralism, explains them as well.

The Clarke/Rowe version of the Cosmological Argument is sound only if the Principle of Sufficient Reason is true, but many philosophers, including Rowe, think that there is not adequate evidence for the principle of sufficient reason. I argue that there may be indirect evidence for PSR on the grounds that if we do not accept it, we lose our best justification for an important principle of metaethics, namely, the Principle of Universalizability. To show this, I argue that all the other justifications of the Principle of Universalizability on offer, including Richard Hare's, are inadequate

I present a problem for a prominent kind of conservatism, viz., the combination of traditional moral & religious values, patriotic nationalism, and libertarian capitalism. The problem is that these elements sometimes conflict. In particular, I show how libertarian capitalism and patriotic nationalism conflict via a scenario in which the thing that libertarian capitalists love – unregulated market activity – threatens what American patriots love – a strong, independent America. Unrestricted libertarian rights to buy and sell land would permit the sale of all American territory by private individuals to foreign powers. Patriotic nationalists regard this as outrageous, but libertarian capitalists cannot refuse it.

Walter Sinnott-Armstrong's recent defense of moral skepticism raises the debate to a new level, but I argue that it is unsatisfactory because of problems with its assumption of global skepticism, with its use of the Skeptical Hypothesis Argument, and with its use of the idea of contrast classes and the correlative distinction between "everyday" justification and "philosophical" justification. I draw on Chisholm's treatment of the Problem of the Criterion to show that my claim that I know that, e.g., baby-torture is wrong, is no more question-begging than Sinnott-Armstrong's denial that I know this.

Bertrand Russell famously disparaged Thomas Aquinas as having ‘little of the true philosophic spirit’, because ‘he does not, like the Platonic Socrates, set out to follow wherever the argument may lead.’ Like many of Russell's pronouncements, this is breathtakingly supercilious and unfair. Still, even an enthusiastic admirer of Aquinas may worry that there is something in it, that there is something wrong with religious ‘commitments’ in philosophy. I examine Russell's objection by comparing standards of permissibility in epistemology with standards of permissibility in ethics, where these issues are better understood. I conclude that the epistemic standard behind Russell's criticism is no less contentious in epistemology than, say, direct utilitarianism is in ethics.

This article is not intended to state what I positively believe to be true, but to make a suggestion which I think it well-worth working out. The suggestion is not altogether unfamiliar, but it has certain implications that seem to have been so far overlooked, or at any rate have never been developed. I do not think that it is the duty of a philosopher to confine himself in his publications to working out theories of the truth of which he is convinced.… It is a part of a philosopher's work, as it is of a scientist's, to try out tentative hypotheses and examine their advantages and disadvantages

This paper is an attempt to bring some order to a classic debate over the mind/body problem. I formulate the dualist, identity, and eliminativist positions and then examine the disagreement between eliminativists and their critics. I show how the apparent impasse between eliminativists and non-eliminativists can be helpfully interpreted in the light of the higher-order debate over methodological versus substantive commitments in philosophy. I argue that non-eliminativist positions can be defended using Roderick Chisholm's defense of what he calls "particularism" in the problem of the criterion.

What do Ross’s The Right and the Good; Chisholm’s Theory of Knowledge; Kripke’s Naming and Necessity; and Audi’s The Architecture of Reason have in common? They all advance important philosophical positions, but not so much via analytic arguments as via formal schemas, distinctions, examples, and analogies. They use such formal schemas, etc, to describe the world so as to make some aspect of it manifest. That is, they simply try to ‘tell it like it is’. This ‘method of descriptive manifestation’ is less commonly recognized than it should be given its divergence from the self-image of analytic philosophy.

Is it possible to have moral knowledge? ‘Moral justification skeptics’ hold it is not, because moral beliefs cannot have the sort of epistemic justification necessary for knowledge. This skeptical stance can be summed up in a single, neat argument, which includes the premise that ‘Inductive arguments from non-moral premises to moral conclusions are not possible.’ Other premises in the argument may rejected, but only at some cost. It would be noteworthy, therefore, if ‘inductive inferentialism’ about morals were shown to be at least possible. Some philosophers may suppose that inductive moral arguments from non-moral premises cannot get off the ground, but I show that a perfectly legitimate inductive moral argument exists. This argument has non-moral premises and a moral conclusion, its premises are related to its conclusion in the right way, and it avoids some of the problems of other, better-known arguments from ‘Is’ to ‘Ought’.

Philosophical naturalism is a cluster of views and impulses typically taken to include atheism, physicalism, radical empiricism or naturalized epistemology, and some sort of relativism, subjectivism or nihilism about morality. I argue that a problem arises when the naturalist offers the argument from evil for atheism. Since the argument from evil is a moral argument, it cannot be effectively deployed by anyone who holds the denatured ethical theories that the naturalist typically holds. In the context of these naturalistic ethical theories, the argument from evil typically fails to provide good reason for either the naturalist or the theist to disbelieve in the God of theism. This does not prove that naturalism is false, or that the argument from evil is unsound, but rather that certain naturalists’ use of the argument has been misguided

The Clarke/Rowe version of the Cosmological Argument is sound only if the Principle of Sufficient Reason (PSR) is true, but many philosophers, including Rowe, think that there is not adequate evidence for the principle of sufficient reason. I argue that there may be indirect evidence for PSR on the grounds that if we do not accept it, we lose our best justification for an important principle of metaethics, namely, the Principle of Universalizability. To show this, I argue that all the other justifications of the Principle of Universalizability on offer, including Richard Hare's, are inadequate

According to the cosmological argument, there must be a self-existent being, because, if every being were a dependent being, we would lack an explanation of the fact that there are any dependent beings at all, rather than nothing. This argument faces an important, but little-noticed objection: If self-existent beings may exist, why may not also self-explanatory facts also exist? And if self-explanatory facts may exist, why may not the fact that there are any dependent beings be a self-explanatory fact? And if that fact is self-explanatory, why make recourse to self-existent beings? This line of questioning is surprisingly hard to answer, but I find resources for an answer in Bertrand Russell's logical atomism.

Walter Sinnott-Armstrong’s recent defence of moral scepticism raises the debate to a new level, but I argue that it is unsatisfactory because of problems with its assumption of global scepticism, with its use of the Sceptical Hypothesis Argument, and with its use of the idea of contrast classes and the correlative distinction between ‘everyday’ justification and ‘philosophical’ justification. I draw on Chisholm’s treatment of the Problem of the Criterion to show that my claim that I know that, e.g., baby-torture is wrong, is no more question-begging than Sinnott-Armstrong’s denial that I know this.

Alexander Miller has recently considered an ingenious extension of Frank Jackson and Philip Pettit's account of 'program explanation' as a way of defending non-reductive naturalist versions of moral realism against Harman's explanatory criticism. Despite the ingenuity of this extension, Miller concludes that program explanation cannot help such moral realists in their attempt to defend moral properties. Specifically, he argues that such moral program explanations are dispensable from an epistemically unlimited point of view. I show that Miller's argument for this negative claim is inadequate, and that he has, in spite of himself, identified a promising defence of moral realism.

The best judge of the soundness of a philosophical argument is the philosopher with the greatest philosophical aptitude, the deepest knowledge of the relevant subject matter, the most scrupulous character, and a disinterested position with respect to the subject matter. This last feature is important because even a highly intelligent and scrupulous judge may find it hard to reach the right conclusion about a subject in which he or she has a vested interest. When the subject of inquiry is the soundness of theistic arguments, the best judge will be the most intelligent and scrupulous philosopher who is also disinterested in the soundness of the theistic argument under consideration. I argue that, in this case, the disinterestedness requirement is best satisfied by the theist whose belief in God is “properly basic”, and in the course of defending this argument I uncover a little-recognized desideratum for theistic arguments.

This paper is critical examination of eliminativism in the philosophy of mind. I begin by identifying eliminativism over and against two other positions in the mind/brain debate. I examine a 'postulational' version of the argument and Richard Rorty's version, arguing that the former is best interpreted as an attempt to eliminate singular terms whereas the latter is best interpreted as an attempt to eliminate predicates. I then set the eliminativism debate in the context of the metaphilosphical debate over substantive vs methodological commitments, concluding that the non-eliminativists/particularists need not find the eliminativist argument compelling.
