Christine M. Korsgaard, The Constitution of Agency: Essays on Practical Reason and Moral Psychology (Oxford: Oxford University Press, 2008), x + 345 pp. Christine Korsgaard is one of our most stimulating and arresting voices in moral philosophy.

(1) It is a style whose candid vitality is very effective in communicating, that is, sharing, both the seriousness and the fun of first-hand philosophical investigation.
