Abstract: Leibniz's Law (or as it sometimes called, 'the Indiscerniblity of Identicals') is a widely accepted principle governing the notion of numerical identity. The principle states that if a is identical to b, then any property had by a is also had by b. Leibniz's Law may seem like a trivial principle, but its apparent consequences are far from trivial. The law has been utilised in a wide range of arguments in metaphysics, many leading to substantive and controversial conclusions. This article discusses the applications of Leibniz's Law to arguments in metaphysics. It begins by presenting a variety of central arguments in metaphysics which appeal to the law. The article then proceeds to discuss a range of strategies that can be drawn upon in resisting an argument by Leibniz's Law. These strategies divide into three categories: (i) denying Leibniz's Law; (ii) denying that the argument in question involves a genuine application of the law; and (iii) denying that the argument's premises are true. Strategies falling under each of these three categories are discussed in turn.

Introduction: What is wisdom? Remarkably few contemporary analytic philosophers have proposed an answer to this ancient question. I think the question is interesting and deserves some careful attention. In this paper, I will present and evaluate several analyses of wisdom. I will then defend my own analysis of wisdom.

Publisher's Note: Could gender, race, and sexuality be relevant to knowledge? Although their positions and arguments differ in several respects, feminists have asserted that science, knowledge, and rationality cannot be severed from their social, political, and cultural aspects. This book presents a comprehensive introduction to feminist epistemologies situated at the intersection of philosophical, sociological, and cultural investigations of knowledge. It provides several critiques of more traditional approaches, and explores the alternatives proposed by feminists. In particular, this book contains extensive discussions of topics such as objectivity, rationality, power, and subject. Drawing on a variety of sources, the author also argues that when knowledge is conceived in terms of practices, it becomes possible to see it as normative and socially constituted."

Introduction: This article discusses expected utility theory as a normative theory - that is, a theory of how people should make decisions. In classical economics, expected utility theory is often used as a descriptive theory - that is, a theory of how people do make decisions - or as a predictive theory - that is, a theory that, while it may not accurately model the psychological mechanisms of decision-making, correctly predicts people's choices. Expected utility theory makes faulty predictions about people's decisions in many real-life choice situations (see Kahneman & Tversky 1982); however, this does not settle whether people should make decisions on the basis of expected utility considerations. The expected utility of an act is a weighted average of the utilities of each of its possible outcomes, where the utility of an outcome measures the extent to which that outcome is preferred, or preferable, to the alternatives. The utility of each outcome is weighted according to the probability that the act will lead to that outcome. Section 1 fleshes out this basic definition of expected utility in more rigorous terms, and discusses its relationship to choice. Section 2 discusses two types of arguments for expected utility theory: representation theorems, and long-run statistical arguments. Section 3 considers objections to expected utility theory; section 4 discusses its applications in philosophy of religion, economics, ethics, and epistemology.
