Some writers about the history of philosophy in Canada have wondered why it should be studied. That is a worthy question, but it is not the one I want to discuss here. I am going to assume there are good reasons for doing so because I want to consider some general features of the subject of such studies and to determine what has to be done to establish certain descriptive claims about it. I will also point out some concerns I have about the proper explanation of certain interesting features of Canadian philosophic activity, and I will present a brief evaluation of one major study. I will do this with the aid of a contention that the study of the history of an intellectual discipline is a little like an evolutionary study of a biological species, but I will close by pointing out one reason for doing history which goes beyond description, and even explanation, of the past.
