Abstract

It has become common to distinguish between two kinds of ethical concepts: thick and thin ones. Bernard Williams, who coined the terms, explains that thick concepts such as “coward, lie, brutality, gratitude and so forth” are marked by having greater empirical content than thin ones. They are both action-guiding and world-guided: If a concept of this kind applies, this often provides someone with a reason for action… At the same time, their application is guided by the world. A concept of this sort may be rightly or wrongly applied, and people who have acquired it can agree that it applies or fails to apply to some new situation. Thin concepts are concepts such as good and bad, right and wrong, obligation and duty. Judgments applying thick concepts have been seen as lending support to the possibility of explaining moral knowledge, and objectivity in ethics. It appears that due to their empirical content – their world-guidedness – judgments employing thick concepts can be true or false, depending on whether they get the worldly facts right. In addition they provide reasons for action – they are action-guiding – and thus may provide the starting point of a realist account of practical reasons: the view that reasons are facts and whether or not a person has a reason to act does not (normally) depend on her attitudes. The cruelty of an action is a reason not to perform it or to prevent it; that an action is kind is a reason in its favour. Of course these remarks aren’t conclusive – far from it. But even so, some non-cognitivists may regard them as completely wrongheaded, and so does Bernard Williams even though he is not a non-cognitivist. However, he believes that having a practical reason does depend on a person’s attitudes and motives. A certain worry about thick concepts will make clear what the problem is. It has most expressly been raised by Simon Blackburn, who sees it as undermining even the most superficial plausibility of moral cognitivism, as well as the claim that the properties picked out by thick concepts provide reasons. While we may readily accept that the kindness of an action or the fact that it is required by justice is a reason to perform it, there are many thick concepts whose action-guiding role we would reject. Some derogatory – e.g., racist or sexist - words express thick concepts too, Blackburn notes. And surely there are no racist or sexist truths. Furthermore there are concepts that some people use evaluatively (like chaste or obscene), but many of us do not regard the propositions in which those concepts feature as even prima facie reason giving. In raising these points, Blackburn claims that it is morally objectionable to regard the facts asserted in propositions which employ thick concepts as action-guiding because it leads to “a conservative and ultimately self-serving complacency.” As he sees it, the problem is that if we believe that the correct application of thick concepts yields evaluative truths and that evaluative truths state reasons for actions, we seem to be committed to accepting that some people are, say, fat, derog., and therefore to be ridiculed, and that there is at least a pro tanto reason to lead a chaste life, or feel affection towards cute women. Therefore, the view that all evaluative properties provide reasons for action or for attitudes such as admiration, affection or (dis)approval must be rejected. I will call this worry henceforth Blackburn’s challenge. The challenge is that understanding judgments employing thick concepts as expressing evaluative truths and providing reasons for actions or for attitudes leads to a morally unacceptable view. Blackburn suggests instead that we should separate the conditions for applying thick concepts and the reasons that we have in virtue of the concept applying. She may be cute, yes, but that is not a reason for “admiration and arousal.” …it is morally vital that we proceed by splitting the input from the output in such a case. By refusing to split we fail to open an essential specifically normative dimension of criticism. According to Blackburn, the meaning of thick concepts is made up of two distinct and in principle separable components: a descriptive one and the expression of an attitude. The truth-aptness and cognitive appearance of judgments employing thick concepts is explained by the descriptive component alone. Blackburn writes “[w]e get nothing but detachable and flexible attitudes, coupled with delineations of traits of character or action”. I will call this reply to Blackburn’s challenge the separability thesis. I agree with Blackburn that any account of thick concepts has to face and answer the challenge that he poses. In this paper, I will focus on one reply to the challenge which denies separability, namely Bernard Williams’s. Williams answers Blackburn’s challenge, while holding on to a cognitivist understanding of thick concepts. But his particular brand of cognitivism is peculiar: Williams rejects the separability thesis, and claims that correct applications of thick concepts yield evaluative (and not just descriptive) knowledge. But this is a special kind of knowledge. It is confined to a local community. The members of a community which uses certain thick concepts may have reasons to act accordingly, but the non-members do not. And even the reasons of members remain a little fragile: they may not want to continue using their concepts upon thorough reflection. The local knowledge view allows Williams to answer Blackburn’s challenge, because even though thick concepts are evaluative concepts and their application can yield evaluative knowledge, no one who isn’t a member of the relevant community has reason to be guided by the concept. Complementing a cognitivist view of thick concepts with reasons internalism allows Williams to answer the challenge. My aim in this paper is to show that Williams’s position is, despite its initial attraction, untenable. In particular, I am going to show why the internal reasons view is incompatible with Williams’s own understanding of thick concepts. My modest result is that the internalist view of reasons does not help to answer Blackburn’s challenge. My aim in this paper is not to answer the challenge but, rather, to explore the possibility of developing Williams’s attenuated version of cognitivism, and the possibility of combining it with reasons internalism.
