Bernard Williams’ philosophy is shaped by a distinctive and abiding interest in the borderlands between Philosophy and History. He famously considers moral philosophy, and particularly moral theory, to over‐step the border that marks the real ‘limits’ of the discipline, and in his later work he explicitly advances the idea of doing ‘impure’ philosophy, by which he meant philosophy that mixed itself with history. By examining the complex impression left on Williams’ historical self‐consciousness by his engagements with two very different figures (...) in the history of philosophy, namely Descartes and Wittgenstein, I will explore a number of ways in which philosophy and history are closely intertwined for Williams. This will draw out the positive vision he modelled for us of ‘impure’ philosophy—a philosophical style he took to contribute to nurturing philosophy as a humanistic discipline. (shrink)
