In Defence of Thick Concepts

This paper focuses on the way in which thick concepts manage to combine the descriptive and the evaluative. It accepts Blackburn’s suggestion that thick terms have variable relevance, but disputes his conclusion that there are no thick concepts. The views of Wiggins and McDowell on these topics play an important role in the discussion. In the process a richer picture of the thick begins to emerge. The paper ends by considering the question whether the doctrine of the supervenience of the evaluative on the natural can still be sustained as a result.
