In this essay the question whether or not African philosophy exists is considered through an examination of the meaning of doubt. In St. Augustine and Descartes the basic presupposition with regard to doubt is the indubitable certainty that the doubting subject must exist before there can be any doubt at all. By parity of reasoning, African philosophy must first exist before it can doubt its own existence or be doubted by another. The origin and meaning of the term “Africa” is then examined. This culminates in the thesis that, once the indigenous conquered peoples of the continent choose to retain the term “Africa”, then they are entitled to give content and meaning to it.
