Abstract
Does the biography of a philosopher have any relevance to assessing their philosophy? After considering and rejecting three distinct treatments of this question, a different answer is articulated here. Distinguishing between the content and approach of a philosophical text, this article argues that biography is relevant to assessing the approach of the text in three ways: in its socio-historical context, its philosophical context, and its personal context in the life of the philosopher. Such a strategy offers new ways of comparing very different texts and assessing them in terms of the aims of the philosopher writing them.
