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 Gettier problem has stymied epistemologists. But, whether or not this problem is resolvable, we still must face an important question: Why does the Gettier problem arise in the first place? So far, philosophers have seen it as either a problem peculiar to the concept of knowledge, or else an instance of a general problem about conceptual analysis. But I would like to steer a middle course. I argue that the Gettier problem arises because knowledge is a thick concept, and (...) a Gettier-like problem is just what we should expect from attempts at analyzing a thick concept. Section 2 is devoted to establishing the controversial claim that knowledge is thick, and, in Sect. 3, I show that there is a general problem for analyzing thick concepts of which the Gettier problem is a special instance. I do not take a stand on whether the Gettier problem, or its general counterpart, is resolvable. My primary aim is to bring these problems into better focus. (shrink)

Philosophers and linguists currently lack the means to reliably identify evaluative concepts and measure their evaluative intensity. Using a corpus-based approach, we present a new method to distinguish evaluatively thick and thin adjectives like ‘courageous’ and ‘awful’ from descriptive adjectives like ‘narrow,’ and from value-associated adjectives like ‘sunny.’ Our study suggests that the modifiers ‘truly’ and ‘really’ frequently highlight the evaluative dimension of thick and thin adjectives, allowing for them to be uniquely classified. Based on these results, we believe our (...) operationalization may pave the way for a more quantitative approach to the study of thick and thin concepts. (shrink)

A term expresses a thick concept if it expresses a specific evaluative concept that is also substantially descriptive. It is a matter of debate how this rough account should be unpacked, but examples can help to convey the basic idea. Thick concepts are often illustrated with virtue concepts like courageous and generous, action concepts like murder and betray, epistemic concepts like dogmatic and wise, and aesthetic concepts like gaudy and brilliant. These concepts seem to be evaluative, unlike purely descriptive concepts (...) such as red and water. But they also seem different from general evaluative concepts. In particular, thick concepts are typically contrasted with thin concepts like good, wrong, permissible, and ought, which are general evaluative concepts that do not seem substantially descriptive. When Jane says that Max is good, she appears to be evaluating him without providing much description, if any. Thick concepts, on the other hand, are evaluative and substantially descriptive at the same time. For instance, when Max says that Jane is courageous, he seems to be doing two things: evaluating her positively and describing her as willing to face risk. Because of their descriptiveness, thick concepts are especially good candidates for evaluative concepts that pick out properties in the world. Thus they provide an avenue for thinking about ethical claims as being about the world in the same way as descriptive claims. -/- Thick concepts became a focal point in ethics during the second half of the twentieth century. At that time, discussions of thick concepts began to emerge in response to certain disagreements about thin concepts. For example, in twentieth-century ethics, consequentialists and deontologists hotly debated various accounts of good and right. It was also claimed by non-cognitivists and error-theorists that these thin concepts do not correspond to any properties in the world. Dissatisfaction with these viewpoints prompted many ethicists to consider the implications of thick concepts. The notion of a thick concept was thought to provide insight into meta-ethical questions such as whether there is a fact-value distinction, whether there are ethical truths, and, if there are such truths, whether these truths are objective. Some ethicists also theorized about the role that thick concepts can play in normative ethics, such as in virtue theory. By the beginning of the twenty-first century, the interest in thick concepts had spread to other philosophical disciplines such as epistemology, aesthetics, metaphysics, moral psychology, and the philosophy of law. -/- Nevertheless, the emerging interest in thick concepts has sparked debates over many questions: How exactly are thick concepts evaluative? How do they combine evaluation and description? How are thick concepts related to thin concepts? And do thick concepts have the sort of significance commonly attributed to them? This article surveys various attempts at answering these questions. (shrink)

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)

Thick terms and concepts in ethics somehow combine evaluation and non-evaluative description. The non-evaluative aspects of thick terms and concepts underdetermine their extensions. Many writers argue that this underdetermination point is best explained by supposing that thick terms and concepts are semantically evaluative in some way such that evaluation plays a role in determining their extensions. This paper argues that the extensions of thick terms and concepts are underdetermined by their meanings in toto, irrespective of whether their extensions are partly (...) determined by evaluation; the underdetermination point can therefore be explained without supposing that thick terms and concepts are semantically evaluative. My argument applies general points about semantic gradability and context-sensitivity to the semantics of thick terms and concepts. (shrink)
