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.

Most of us think we can always enlarge our knowledge base by accepting things that are entailed by (or logically implied by) things we know. The set of things we know is closed under entailment (or under deduction or logical implication), which means that we know that a given claim is true upon recognizing, and accepting thereby, that it follows from what we know. However, some theorists deny that knowledge is closed under entailment, and the issue remains controversial. The arguments against closure include the following
