This interesting volume (published by Yale University Press, 1974) offers sustenance to almost all who have an appetite for the problems of practical reason. As the Proceedings of the First Bristol Conference on Critical Philosophy, it contains the five papers presented there, with the remarks of commentators and, in three cases, replies. First, the bill of fare.

Roderick Chisholm opens with “Practical Reason and the Logic of Requirement”, about which I shall say no more than to quote the beginning of G.E.M. Anscombe's comment: “It is characteristic of Professor Chisholm to carry one always by a succession of small harmless-looking moves which then suddenly enable him to pull out some large kicking rabbits like a conjurer operating with a hat. This time he has produced the large kicking rabbits, but the initial movements do not seem as unsuspicious as usual.” (pp 17–18) Those who like what Chisholm does, will find fine detail in his paper, the comments, and his reply; unfortunately, for me Professor Chisholm's rabbits have the disconcerting invisibility of Harvey.
