It must be considered that a man who only does what everyone of the society to which he belongs would do is not a dishonest man.A lack of confidence in the ability of a tribunal correctly to estimate evidence of states of mind and the like can never be sufficient ground for excluding from enquiry the most fundamental element in a rational and humane criminal code.

As is well known, the Humean account of causal inference gives a central location to inference habits. Some of these habits one can discipline. Thus, one can so discipline oneself as to reason in accordance with the “rules by which to judge of causes and effects”, that is, one can discipline oneself to think scientifically, rather than, say, in accordance with the rules of prejudice, or of superstition. All such judgments, even those of science, are, however, upon the Humean account (...) fallible. Some, or rather very many, have raised the issue about how any such causal judgment or inference is justified. That is, how can such inference habits be justified, shown to be reasonable. Hume meets this challenge by arguing that there are some habits all men do and must have. Because we must have them we ought to have them. They are, therefore, justified. (shrink)

In section I, I lay out key components of my favoured non-cognitivist interpretation of Mill's metaethics. In section II, I respond to several objections to this style of interpretation posed by Christopher Macleod. In section III, I respond to David Brink's treatment of the well-known ‘competent judges’ passage in Mill'sUtilitarianism. I argue that important difficulties face both Brink'sevidential interpretationand the rivalconstitutive interpretationthat he proposes but rejects. I opt for a third interpretative option that I call thepsychological interpretation. This interpretation makes (...) sense of otherwise difficult aspects of chapter IV ofUtilitarianism. In section IV, I offer some reasons for rejecting Nicholas Drake's claim that Mill is ultimately best characterized as a Humean constructivist. If we accept Drake's suggestion that Mill's non-cognitivism is compatible with his being a constructivist, I argue, we should view Mill as putting forward a distinctively Millian form of constructivism rather than a Humean one.
