Thick Concepts

An international team of experts explores the distinction between 'thin' concepts (general, evaluative terms like 'good' and 'bad') and 'thick' concepts (more specific concepts, such as 'brave', or 'rude'). Their essays touch on key debates in metaethics about the evaluative and normative, and raise fascinating questions about how language works. What is the difference between judging someone to be good and judging them to be kind? Both judgements are typically positive, but the latter seems to offer more description of the person: we get a more specific sense of what they are like. Very general evaluative concepts (such as good, bad, right and wrong) are referred to as thin concepts, whilst more specific ones (including brave, rude, gracious, wicked, sympathetic, and mean) are termed thick concepts. In this volume, an international team of experts addresses the questions that this distinction opens up. How do the descriptive and evaluative functions or elements of thick concepts combine with each other? Are these functions or elements separable in the first place? Is there a sharp division between thin and thick concepts? Can we mark interesting further distinctions between how thick ethical concepts work and how other thick concepts work, such as those found in aesthetics and epistemology? How, if at all, are thick concepts related to reasons and action? These questions, and others, touch on some of the deepest philosophical issues about the evaluative and normative. They force us to think hard about the place of the evaluative in a (seemingly) nonevaluative world, and raise fascinating issues about how language works.
