Book excerpt: Sage Philosophy is an anthology of three main parts: Part one contains papers by Odera Oruka clearing the way and arguing about his research over the last decade on indigenous sages in Kenya. Part Two introduces verbatim interviews with a given number of those sages, while Part Three consists of published papers by scholars who are critics or commentators on the Oruka project. The author has spent the last decade in Kenya carrying out his research. It is the general stand of the book that the sages turn out to be thinkers or philosophers in no trivial sense, despite their lack of modern formal education. This study is a critique for all those scholars who hitherto have found no practice of critical philosophy in traditional Africa.
