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.
Normative Theories of Rational Choice: Expected Utility
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.
The epistemology of Perception
Abstract: An overview of the epistemology of perception, covering the nature of justification, immediate justification, the relationship between the metaphysics of perceptual experience and its rational role, the rational role of attention, and cognitive penetrability. The published version will contain a smaller bibliography, due to space constraints in the volume.
Do Visual Experiences have contents?
Abstract: This paper argues that despite the differences between perception and belief, perception involves states that are importantly similar to beliefs: conscious visual experiences. According to the Content View, these experiences have contents in the form of accuracy conditions. The paper develops and defends the Content View, discusses its significance, and argues that contrary to what is often supposed, the Content View is compatible with Naive Realist disjunctivism.
Wisdom
Introduction: What is wisdom? Philosophers, psychologists, spiritual leaders, poets, novelists, life coaches, and a variety of other important thinkers have tried to understand the concept of wisdom. This entry will provide a brief and general overview, and analysis of, several philosophical views on the topic of wisdom. It is not intended to capture the many interesting and important approaches to wisdom found in other fields of inquiry. Moreover, this entry will focus on several major ideas in the Western philosophical tradition. In particular, it will focus on five general approaches to understanding what it takes to be wise: (1) wisdom as epistemic humility, (2) wisdom as epistemic accuracy, (3) wisdom as knowledge, (4) a hybrid theory of wisdom, and (5) wisdom as rationality.
Feminist Social Epistemology
Summary: Survey article on feminist epistemology and its intersection with social epistemology. Includes discussion on topics such as the historical development of feminist epistemology as well as on epistemic injustice and the epistemology of ignorance.
Du Châtelet on Freedom, Self-Motion, and Moral Necessity
Abstract: This paper explores the theory of freedom that Emilie du Châtelet advances in her essay “On Freedom.” Using contemporary terminology, we can characterize this theory as a version of agent-causal compatibilism. More specifically, the theory has the following elements: (a) freedom consists in the power to act in accordance with one’s choices, (b) freedom requires the ability to suspend desires and master passions, (c) freedom requires a power of self-motion in the agent, and (d) freedom is compatible with moral necessity but not with physical necessity. While these elements may at first appear disparate, the paper shows that they fit together quite well. The resulting theory is a surprising combination of doctrines that appear to be based on Samuel Clarke’s libertarian account of free will and doctrines that are reminiscent of the compatibilist accounts of John Locke, Anthony Collins, Gottfried Leibniz, and Thomas Hobbes.
Evolutionary Debunking of Moral Realism
Abstract: Evolutionary debunking arguments move from a premise about the influence of evolutionary forces on our moral beliefs to a skeptical conclusion about those beliefs. My primary aim is to clarify this empirically grounded epistemological challenge. I begin by distinguishing among importantly different sorts of epistemological attacks. I then demonstrate that instances of each appear in the literature under the ‘evolutionary debunking- title. Distinguishing them clears up some confusions and helps us better understand the structure and potential of evolutionary debunking arguments.
A History of Women’s Political Thought in Europe, 1400–1700
Publisher’s Note: This ground-breaking book surveys the history of women’s political thought in Europe from the late medieval period to the early modern era. The authors examine women’s ideas about topics such as the basis of political authority, the best form of political organisation, justifications of obedience and resistance, and concepts of liberty, toleration, sociability, equality, and self-preservation. Women’s ideas concerning relations between the sexes are discussed in tandem with their broader political outlooks; and the authors demonstrate that the development of a distinctively sexual politics is reflected in women’s critiques of marriage, the double standard, and women’s exclusion from government. Women writers are also shown to be indebted to the ancient idea of political virtue, and to be acutely aware of being part of a long tradition of female political commentary. This work will be of tremendous interest to political philosophers, historians of ideas, and feminist scholars alike.
Paradox of Dignity: Everyday Racism and the Failure of Multiculturalism
Abstract: Liberal multiculturalism was introduced to support integration and anti-racism, but everyday racism continues to be a fact of life. This paper analyzes first some frameworks and problems that race and racism raise, and discusses two common liberal approaches for solving the problem of racism: the individualized conception of dignity and the social conception of multiculturalism. I argue that the ontological and epistemological assumptions involved in both of these approaches, coupled with the absence of the political-progressive notion of «race» in Germany, in fact obscure important paths against racism. Lastly I introduce a politico-existential position from Cornel West and conclude that racism should be seen as a failure of a democratic process rather than a problem of race.
