If A is better than B and B is better than C, then A is better than C, right? Larry Temkin and Stuart Rachels say: No! Betterness is nontransitive, they claim. In this paper, I discuss the central type of argument advanced by Temkin and Rachels for this radical idea, and argue that, given this view very likely has sceptical implications for practical reason, we would do well to identify alternative responses. I propose one such response, which employs the idea (...) that rational agents might regard some options as incommensurate in value, and will reasonably employ a heuristic of status quo maintenance to avoid suboptimal choices from incommensurate goods.

This paper deals with the truth-Conditions and the logic for vague languages. The use of supervaluations and of classical logic is defended; and other approaches are criticized. The truth-Conditions are extended to a language that contains a definitely-Operator and that is subject to higher order vagueness.

John Pollock aims to construct a theory of rational decision making for real agents--not ideal agents. Pollock argues that theories of ideal rationality are largely irrelevant to the decision making of real agents. Thinking about Acting aims to provide a theory of "real rationality.".

In choosing between moral alternatives -- choosing between various forms of ethical action -- we typically make calculations of the following kind: A is better than B; B is better than C; therefore A is better than C. These inferences use the principle of transitivity and are fundamental to many forms of practical and theoretical theorizing, not just in moral and ethical theory but in economics. Indeed they are so common as to be almost invisible. What Larry Temkin's book shows (...) is that, shockingly, if we want to continue making plausible judgments, we cannot continue to make these assumptions. Temkin shows that we are committed to various moral ideals that are, surprisingly, fundamentally incompatible with the idea that "better than" can be transitive. His book develops many examples where value judgments that we accept and find attractive, are incompatible with transitivity. While this might seem to leave two options -- reject transitivity, or reject some of our normative commitments in order to keep it -- Temkin is neutral on which path to follow, only making the case that a choice is necessary, and that the cost either way will be high. Temkin's book is a very original and deeply unsettling work of skeptical philosophy that mounts an important new challenge to contemporary ethics. (shrink)

If a potential person would have a good life if he were to come into existence, can we coherently regard his coming into existence as better for him than his never coming into existence? And can we regard the situation in which he never comes into existence as worse for him? In this paper, we argue that both questions should be answered affirmatively. We also explain where prominent arguments to differing conclusions go wrong. Finally, we explore the relevance of our (...) answers to issues in population ethics. (shrink)

The authors of this paper earlier argued that concrete objects, such as things or persons, may have final value , which is not reducible to the value of states of affairs that concern the object in question.Our arguments have been challenged. This paper is an attempt to respond to some of these challenges, viz. those that concern the reducibility issue. The discussion presupposes a Brentano-inspired account of value in terms of fitting responses to value bearers. Attention is given to a (...) yet another type of reduction proposal, according to which the ultimate bearers of final value are abstract particulars rather than abstract states or facts. While the proposal is attractive , it confronts serious difficulties. To recognise tropes as potential bearers of final value, along with other objects, is one thing; but to reduce the final value of concrete objects to the final value of tropes is another matter.

In "Futurc Generations: Further Problems,"‘ and Part Four of Reasons and Persons} Derek Pariit raises many perplexing questions. Although some think his ingenious arguments little more than delightful puzzles, I believe they challenge some of our deepest beliefs. In this article, I examine some of Pariit’s arguments, focusing mainly on "The Mere Addition Paradox." If my analysis is correct, Parfit’s arguments have extremely interesting and important implications that not even Pariit rcalized. In Part I, I present ParHt’s argument for the (...) Merc Addition Paradox, and show that given Pa.rHt’s assumptions, a radical conclusion seems t0 follow; the notion of "bctter th2m"—indced, even the notion of "aH things.. (shrink)

This dissertation provides a defense of the normative intuition known as the Procreation Asymmetry, according to which there is a strong moral reason not to create a life that will foreseeably not be worth living, but there is no moral reason to create a life just because it would foreseeably be worth living. Chapter 1 investigates how to reconcile the Procreation Asymmetry with our intuitions about another recalcitrant problem case in population ethics: Derek Parfit's Non-Identity Problem. I show that what (...) has prevented philosophers from developing a theory that gives a satisfactory account of both these problems is their tacit commitment to a teleological conception of well-being, as something to be `promoted'. Replacing this picture with one according to which our reasons to confer well-being on people are conditional on their existence allows me to do better. It also enables us to understand some of the deep structural parallels between seemingly disparate normative phenomena such as procreating and promising. Chapter 2 attempts to connect my defense of the Procreation Asymmetry to corresponding evaluative claims about the goodness of the outcomes produced by procreative decisions. I propose a view, the `biconditional buck-passing view of outcome betterness', according to which facts about the comparative goodness of outcomes are a function of our reasons for bringing about one outcome rather than another under certain conditions. This enables me to derive an Evaluative Procreation Asymmetry from the corresponding normative claims established in Chapter 1. The biconditional buck-passing view also provides me with a principled basis for challenging a version of the Independence of Irrelevant Alternatives Principle. This, in turn, permits me to provide a novel solution to another famous problem in population ethics: Parfit's Mere Addition Paradox. Finally, in Chapter 3, I rebut some key objections to the Procreation Asymmetry by showing that upholding it does not commit us to anti-natalism and that it is compatible with a moral concern for the long-term survival of humanity.
