Cornell realists maintain that irreducible moral properties have earned a place in our ontology in virtue of the indispensable role they play in a variety of explanations. These explanations can be divided into two groups: those that employ thin ethical concepts and those that employ thick ethical concepts. Recent work on thick concepts suggests that they are not inherently evaluative in their meaning. If correct, this creates problems for the moral explanations of Cornell realists, since the most persuasive moral explanations (...) are those that employ thick concepts. If thick concepts are not inherently evaluative, then the most plausible explanations on offer cannot support Cornell realism. Moral explanations employing thin concepts, however, are too flimsy to support the view. Unless proponents can develop a compelling story about thick concepts or thin explanations, Cornell realism is in trouble. (shrink)

In ethics, aesthetics and increasingly in epistemology, a distinction is drawn between thick and thin evaluative concepts. A common characterisation of the distinction is that thin concepts have only evaluative content, whereas thick concepts combine evaluative and descriptive content. Because of this combination, it is again commonly thought that thick concepts have various distinctive powers including the power to undermine the distinction between fact and value. This paper discusses the accuracy of this view of the thick concepts debate, as well (...) as assessing the prospects for a thick concepts argument against the fact value distinction, while introducing the three main philosophical positions on the nature of thick concepts.

Legality is a monograph scoring distinct contributions across the board of jurisprudential discourse. Among the most prominent arguments marshalled in this book is an impressively robust defence of reductionism about legal norms. The concept of a plan is invoked in the service of delivering a formidable task, that of disembarrassing the legal philosopher of the quest for what makes legal norms metaphysically distinct. The answer is simple, yet relies on an intricate chain of arguments: talk of legal norms is just (...) a linguistic convention for referring to a metaphysically more versatile kind of object, namely, plans. This essay aims to record and evaluate the metaphysical implications of this reductionist turn. More precisely, it shall locate two defensible, yet sharply divergent, variants of plan positivism which Shapiro’s dense analysis appears to conflate at the expense of his theory’s explanatory ambitions. The concern this essay intends to raise regards an... (shrink)
