Adherents of the epistemological position called internalism typically believe that the view they oppose, called externalism, is such a new and radical departure from the established way of seeing knowledge that its implications are uninteresting. Perhaps itis relatively novel, but the approach to knowledge with the greatest antiquity is the one that equates it withcertainty, and while this conception is amenable to the demands of the internalist, it is also a non-starter in the opinion of almost all contemporary epistemologists since obviously it directly implies that we know nothing about the world. Perhaps skepticism is correct, but there are conceptions of knowledge at least as plausible as the certainty equation that do not obviously land us there. It is its promise along these lines that makes the so-called traditional conception of knowledge initially interesting. But contrary to popular belief, the traditional conception cannot be claimed by internalists if it is to have any chance at all in avoiding skepticism; to avoid skepticism, I shall argue, it has to have an externalist element.Moreover, each of the departures from the traditional view that appears in the Gettier literature is externalist as well, or at least all of the ones of which I am aware. The only genuine forms of internalism are those held by philosophers who draw a fairly sharp line between knowledge and justified belief, ignore the former, then offer an internalist account of the latter. This approach is very common and very plausible. But it is not as useful as is often thought; in particular, I shall suggest, it must succumb to a form of skepticism.

I examine an argument that appears to take us from Parfit’s [Reasons and Persons, Oxford: Clarendon Press (1984)] thesis that we have no reason to fulfil desires we no longer care about to the conclusion that the effect of posthumous events on our desires is a matter of indifference (the post-mortem thesis). I suspect that many of Parfit’s readers, including Vorobej [Philosophical Studies 90 (1998) 305], think that he is committed to (something like) this reasoning, and that Parfit must therefore give up the post-mortem thesis. However, as it turns out, the argument is subtly equivocal and does not commit Parfit to the post-mortem thesis. I close with some doubts about Parfit’s case for his indifference thesis.

‘Skepticism’ refers primarily to two positions. Knowledge skepticism says there is no such thing as knowledge, and justification skepticism denies the existence of justified belief. How closely the two views are related depends on the relationship between knowledge and justification: if knowledge entails justified belief, as many theorists say, then justification skepticism entails knowledge skepticism (but not vice versa). Either form of skepticism can be limited in scope. Global (or radical) skepticism challenges the epistemic credentials of all beliefs, saying that no one knows anything, or no belief is justified. More local skepticism is restricted to some domain; thus some skeptics question the epistemic credentials of beliefs about other minds (but not beliefs about one’s own mind), or beliefs concerning empirical matters (but not concerning a priori matters).

This volume meets the increasing interest in a range of philosophical issues connected with the nature and significance of life and death, and the ethics of killing. What is it to be alive and to die? What is it to be a person? What must time be like if we are to persist? What makes one life better than another? May death or posthumous events harm the dead? The chapters in this volume address these questions, and also discuss topical issues such as abortion, euthanasia, and suicide. They explore the interrelation between the metaphysics, significance, and ethics of life and death, and they discuss the moral significance of killing both people and animals, and the extent to which death harms them. The volume is for all those studying the philosophy of life and death, for readers taking applied ethics courses, and for those studying ethics and metaphysics more generally.

The harm thesis says that death may harm the individual who dies. The posthumous harm thesis says that posthumous events may harm those who die. Epicurus rejects both theses, claiming that there is no subject who is harmed, no clear harm which is received, and no clear time when any harm is received. Feldman rescues the harm thesis with solutions to Epicurus' three puzzles based on his own version of the deprivation account of harm. But many critics, among them Lamont, Grey, Feit and Bradley, have rejected Feldman's solution to the timing puzzle, offering their own solutions in its place. I discuss these solutions to the timing puzzle, and defend the view that while we are alive we may incur harm for which death and posthumous events are responsible

Can we render death harmless to us by perfecting life, as the ancient Epicureans and Stoics seemed to think? It might seem so, for after we perfect life—assuming we can—persisting would not make life any better. Dying earlier rather than later would shorten life, but a longer perfect life is no better than a shorter perfect life, so dying would take nothing of value from us. However, after sketching what perfecting life might entail, I will argue that it is not a desirable approach to invulnerability after all.

According to Epicurus (1966a,b), neither death, nor anything that occurs later, can harm those who die, because people who die are not made to suffer as a result of either. In response, many philosophers (e.g., Nagel 1970, Feinberg 1984, and Pitcher 1984) have argued that Epicurus is wrong on both counts. They have defended the mortem thesis: death may harm those who die. They have also defended the post-mortem thesis: posthumous events may harm people who die. Their arguments for this joint view are by now quite familiar, and there is no need to rehearse them here (for a summary, see Luper 2002). Instead, our topic is a third position, which carves out intermediate ground between the other two. The intermediate view takes the mortem thesis for granted, like the critics of Epicurus, but rejects the post-mortem thesis, like Epicurus himself. For Epicurus’ project—the attainment of ataraxia, or equanimity—the intermediate view is almost useless (we are not tranquil if we regard death as a tragedy whose peculiarity is that it frees us from the possibility of any further misfortune); however, it is far more plausible than Epicurus’ own position since it avoids his absurd claim that death cannot harm us, while retaining his view that events occurring while we are dead and gone cannot harm us. According to the proponent of the intermediate view, when we understand the harm death inflicts, we must reject the idea that events following death can be bad for us. The damage death itself does is so severe that people are not subject to harm by any subsequent events. Thus the intermediate view rests on the mortem thesis together with the immunity thesis: death leaves its victims immune from posthumous harm.

Ideally, our account of knowledge would help us to understand the appeal of (and flaws in) skepticism,2 while remaining consistent with our ‘intuitions,' and supporting epistemic principles that seem eminently plausible. Of course, we don't always get what we want; we may not be able to move from intuitions and principles to an account that fully squares with them. As a last resort, we may have to move in the other direction, and give up intuitions or principles that are undermined by an otherwise compelling account of knowledge, so as to achieve ‘reflective equilibrium.'3 But last resorts come last.

In early essays and in more recent work, Fred Dretske argues against the closure of perception, perceptual knowledge, and knowledge itself. In this essay I review his case and suggest that, in a useful sense, perception is closed, and that, while perceptual knowledge is not closed under entailment, perceptually based knowledge is closed, and so is knowledge itself. On my approach, which emphasizes the safe indication account of knowledge, we can both perceive, and know, that sceptical scenarios (such as being a brain in a vat) do not hold.

Suppose Ted is in an ordinary house in good viewing conditions and believes red, his table is red, entirely because he sees his table and its color; he also believes not-white, it is false that his table is white and illuminated by a red light, because not-white is entailed by red. The following three claims about this table case clash, but each seems plausible: 1. Ted’s epistemic position is strong enough for him to know red. 2. Ted cannot know not-white on the basis of red. 3. The epistemic closure principle, suitably restricted, is true. Stewart Cohen has called this three-way clash of intuitions the problem of easy knowledge. If we wish to resolve the clash without accepting skepticism, we seem to have two options. According to the hard argument, the best response is to reject 3. The easy argument rejects 2. But there may be a third alternative, the reverse argument, which rejects 1 without ceding a substantial amount of ground to the skeptic. In this essay I criticize recent versions of the reverse argument and the hard argument, thereby lending support to the easy argument

Epistemic relativism rejects the idea that claims can be assessed from a universally applicable, objective standpoint. It is greatly disdained because it suggests that the real ‘basis’ for our views is something fleeting, such as ‘‘the techniques of mass persuasion’’ (Thomas Kuhn 1970) or the determination of intellectuals to achieve ‘‘solidarity’’ (Rorty 1984) or ‘‘keep the conversation going’’ (Rorty 1979). But epistemic relativism, like skepticism, is far easier to despise than to convincingly refute, for two main reasons. First, its definition is unclear, so we cannot always tell where relativism leaves off and other views, such as skepticism or subjectivism, begin. Consequently, it can be difficult to tell when a criticism has done enough. Second, the grounds for relativism are unclear, which can make it hard to know how to attack it or whether we have dismantled all of the ways of supporting it.

The Philosophy of Death is a discussion of the basic philosophical issues concerning death, and a critical introduction to the relevant contemporary philosophical literature. Luper begins by addressing questions about those who die: What is it to be alive? What does it mean for you and me to exist? Under what conditions do we persist over time, and when do we perish? Next, he considers several questions concerning death, including: What does dying consist in; in particular, how does it differ from ageing? Must death be permanent? By what signs may it be identified? Is death bad for the one who dies? If so why? Finally he discusses whether, and why, killing is morally objectionable, and suggests that it is often permissible; in particular, suicide, euthanasia and abortion may all be morally permissible. His book is a lively and engaging philosophical treatment of a perennially fascinating and relevant subject.
