So-called "thick" moral concepts are distinctive in that they somehow "hold together" evaluation and description. But how? This paper argues against the standard view that the evaluations which thick concepts may be used to convey belong to sense or semantic content. That view cannot explain linguistic data concerning how thick concepts behave in a distinctive type of disagreements and denials which arise when one speaker regards another's thick concept as "objectionable" in a certain sense. The paper also briefly considers contextualist, (...) presuppositional, and implicature accounts of the evaluative contents of thick concepts, but finds none clearly superior to the others. (shrink)

The distinction between “thick” and “thin” value concepts, and its importance to ethical theory, has been an active topic in recent meta-ethics. This paper defends three claims regarding the parallel issue about thick and thin epistemic concepts. (1) Analogy with ethics offers no straightforward way to establish a good, clear distinction between thick and thin epistemic concepts. (2) Assuming there is such a distinction, there are no semantic grounds for assigning thick epistemic concepts priority over the thin. (3) Nor does (...) the structure of substantive epistemological theory establish that thick epistemic concepts enjoy systematic theoretical priority over the thin. In sum, a good case has yet to be made for any radical theoretical turn to thicker epistemology. (shrink)

Many philosophers have been concerned with the nature of thick normative concepts. In this paper, I try to motivate a different project: understanding the nature of thick normative properties and facts. I propose a ground-theoretic approach to this project. I then argue that some of the simplest and most initially plausible ways of understanding thick facts fail, and that we are forced to accept some initially implausible views. I try to show how these views are not so implausible after all.

I argue that knowledge is a particular kind of concept known as a thick concept. Examples of thick concepts include courage, generosity, loyalty, brutality, and so forth. These concepts are commonly said to combine both evaluation and description, and one of the main goals of this dissertation is to provide a new account of how a thick concept combines these elements. It is argued that thick concepts are semantically evaluative, and that they combine evaluation and description in a way similar (...) to that of concepts like good qua dancer and bad qua violinist. In the final chapter, this basic idea is applied to the concept of knowledge. There, the concept of knowledge is analyzed in terms of good qua belief. The upshot is that two central epistemological problems—the Gettier Problem and the Value Problem—can be resolved. (shrink)

The dissertation is centered around the Moral Virtuosity Project . The central task of the dissertation is to examine what other philosophers have had to say on this topic and ultimately to successfully complete this project. ;Chapter One is concerned exclusively with Aristotle's attempt to complete the Moral Virtuosity Project. I defend the view that Aristotle holds that each moral virtue is a disposition toward proper practical reasoning, action, and emotion within a certain sphere. I critically examine Aristotle's argument for (...) the unity of the virtues. I then try to point to some areas where Aristotle's views on moral virtue fail to correspond with our ordinary common sense views on moral virtue. ;Chapter Two has three main parts. First, I consider Immanuel Kant's attempt to complete the Moral Virtuosity Project. I develop an interpretation of Kant's views on this topic. Second, I take up the topic of the relationship between Aristotle's views on moral virtue and Kant's views on moral virtue. Third, I examine some objections to Kant's views on moral virtue. I conclude that Kant's account of moral virtue goes wrong because it is inextricably tied up with the concept of moral obligation. ;Chapter Three is devoted to critical discussions of contemporary attempts to complete the Moral Virtuosity Project. Authors whose views are discussed include: G. H. von Wright, Philippa Foot, Judith Thomson, Linda Zagzebski, and Thomas Hurka. I conclude that each view has serious problems. ;In Chapter Four I develop a novel account of moral virtue by appealing to the concept of admirability. Drawing on work on virtue by Michael Slote, I try to shed some light on the concept of admirability and distinguish the concept from related concepts. I then appeal to the concept of admirability to explicate the concept of a moral virtue, thus completing the Moral Virtuosity Project. I discuss a number of other topics, including "hard cases", excessive virtue, and two sorts of morally virtuous persons: the Good Hearted Hero and the Conflicted Hero. (shrink)
