In Rethinking the Good, Larry Temkin argues that the common belief in the transitivity of better than is incompatible with various other value judgments to which many of us are deeply committed; accordingly, we should take seriously the possibility that the better than relation is not, in fact, a transitive one. However, although Temkin is right, I think, about the mutual incompatibility of the beliefs in question, for the most part his examples don’t leave me inclined to deny transitivity. Nonetheless, there is one example, involving infinity, that does seem to me particularly troubling.

According to the dominant philosophical tradition, intrinsic value must depend solely upon intrinsic properties. By appealing to various examples, however, I argue that we should at least leave open the possibility that in some cases intrinsic value may be based in part on relational properties. Indeed, I argue that we should even be open to the possibility that an object''s intrinsic value may sometimes depend (in part) on its instrumental value. If this is right, of course, then the traditional contrast between intrinsic value and instrumental value is mistaken.

Most intuitively forceful criticisms of utilitarianism, I believe, reduce to two basic objections. Both arise from the relentlessness of the utilitarian injunction to promote the overall good. On the one hand, this means that agents are permitted to perform an act of any kind whatsoever–provided only that the consequences of that act are better than those of any alternative. In particular, this means that it is permissible to impose tremendous sacrifices or injuries upon someone, if this is the only way to ensure even greater gains for others. But in allowing agents to deliberately impose harm on someone for the sake of others, utilitarianism seems to permit acts which are morally unacceptable. Intuitively, we want to say that rights, or other moral prohibitions, forbid treating people in certain ways–ways allowed by utilitarianism. This, then, is the first major objection: utilitarianism permits too much.

Typically, discussions of well-being focus almost exclusively on the positive aspects of well-being, those elements which directly contribute to a life going well, or better. It is generally assumed, without comment, that there is no need to explicitly discuss ill-being as well—that is, the part of the theory of well-being that specifies the elements which directly contribute to a life going badly, or less well—since (or so it is thought) this raises no special difficulties or problems. But this common assumption is a mistake, since it is far from obvious how to extend even familiar theories of well-being so as to explicitly cover ill-being as well. This paper acts as an introduction to ill-being, noting some of the interesting and overlooked problems ill-being raises for qualitative hedonism, preference theory, and objective list theories. Particular attention is paid, by way of illustration, to the claim that knowledge is an objective good. Assuming this is so, what exactly is the opposite of knowledge, the objective bad which lowers one’s well-being in the same way that knowledge raises it?

What are the limits of well-being? This question nicely captures one of the central debates concerning the nature of the individual human good. For rival theories differ as to what sort of facts directly constitute a person's being well-off. On some views, well-being is limited to the presence of pleasure and the absence of pain. But other views push the boundaries of well-being beyond this, so that it encompasses a variety of mental states, not merely pleasure alone. Some theories then draw the line here, limiting well-being to the presence of the appropriately broadened set of mental states. But still others extend the limits of well-being even further, so that it is constituted in part by facts that are not themselves mental states at all; on such views, well-being is partly constituted by states of affairs that are “external” to the individual's experiences. In this essay, I want to explore some of this debate by focusing on a particular stretch of the dialectic. That is, I want to think hard about a particular connected series of arguments and counterarguments. These arguments – or, at least, the concerns they seek to express – emerge naturally in the give and take of philosophical discussion. Together they make up a rather simple story, whose plot, in very rough terms, is this: first there is an attempt to push the limits of well-being outward, moving from a narrow to a broader conception; then comes the claim that the resulting notion is too broad, and so we must retreat to a narrower conception after all

Anyone who reflects on the way we go about arguing for or against moral claims is likely to be struck by the central importance we give to thinking about cases. Intuitive reactions to cases—real or imagined—are carefully noted, and then appealed to as providing reason to accept various claims. When trying on a general moral theory for size, for example, we typically get a feel for its overall plausibility by considering its implications in a range of cases. Similarly, when we try to refine the statement of a principle meant to cover a fairly specific part of morality, we guide ourselves by testing the various possible revisions against a carefully constructed set of cases. And when arguing against a claim, we take ourselves to have shown something significant if we can find an intuitively compelling counterexample, and such counterexamples almost always take the form of a description of one or another case where the implications of the claim in question seem implausible. Even when we find ourselves faced with a case where we have no immediate and clear reaction, or where we have such a reaction, but others don't share it and we need to persuade them, in what is probably the most common way of trying to make progress we consider various analogies and disanalogies; that is to say, we appeal to still other cases, and by seeing what we want to say there, we discover what it is plausible to say in the original case. In these and other ways, then, the appeal to cases plays a central and ubiquitous role in our moral thinking

000000001. Introduction Call a theory of the good—be it moral or prudential—aggregative just in case (1) it recognizes local (or location-relative) goodness, and (2) the goodness of states of affairs is based on some aggregation of local goodness. The locations for local goodness might be points or regions in time, space, or space-time; or they might be people, or states of nature.1 Any method of aggregation is allowed: totaling, averaging, measuring the equality of the distribution, measuring the minimum, etc.. Call a theory of the good finitely additive just in case it is aggregative, and for any finite set of locations it aggregates by adding together the goodness at those locations. Standard versions of total utilitarianism typically invoke finitely additive value theories (with people as locations). A puzzle can arise when finitely additive value theories are applied to cases involving an infinite number of locations (people, times, etc.). Suppose, for example, that temporal locations are the locus of value, and that time is discrete, and has no beginning or end.2 How would a finitely additive theory (e.g., a temporal version of total utilitarianism) judge the following two worlds? Goodness at Locations (e.g. times) w1:..., 2, 2, 2, 2, 2, 2, 2, 2, 2, ..... w2:..., 1, 1, 1, 1, 1, 1, 1, 1, 1, ..... Example 1 At each time w1 contains 2 units of goodness and w2 contains only 1. Intuitively, we claim, if the locations are the same in each world, finitely additive theorists will want to claim that w1 is better than w2. But it's not clear how they could coherently hold this view. For using standard mathematics the sum of each is the same infinity, and so there seems to be no basis for claiming that one is better than the other.3 (Appealing to Cantorian infinities is of no help here, since for any Cantorian infinite N, 2xN=1xN.)
