What does it mean to be a master of a craft?
Alasdair MacIntyre’s notion of the goods internal to a practice self-consciously separates the standards of practitioners from mere material gain, which constitute “external goods”. As a follower of McCloskey, it seems clear to me that the sacred and the profane are not so cleanly separable. Previously, when I have written about this, I argued that external goods must be internalized in some way. That is, part of the way you become a good carpenter, or good lawyer, or good salesman, is by making money in a good way. That is to say, part of the ethics of a practice is precisely how you deal with your customers or clients or patrons or donors.
If you buy the argument that internal goods exist, what you think about the nature of them probably relates to your beliefs about the nature of morality in general. I have my own thoughts on the matter.
