Anthony Oseghare, a PhD student of Odera Oruka, makes a distinction between sagacity and knowledge. Both involve the acquisition and usage of skills, but they are not identical. Sagacity involves wisdom of a practical nature which is achieved through experience. It has a broader meaning than knowledge. Within sagacity too, there is a sagacity that stops with common sense and a sagacity that transcends common sense. Oseghare's critique, unlike Masolo's and Bodunrin's, is not negative but meant to clarify and enhance Odera Oruka's project.
