This essay examines the profound affinities between Wittgenstein and the historical Socrates. The first five sections argue that similarities between their personalities and circumstances can explain a comparable pattern of philosophical development. The next nine show that many apparently chance similarities between the two men's lives and receptions can be explained by their shared conceptions ofphilosophical method. The last three sections consider the difficulty of practising this method through writing, and examine the solutions which Plato and Wittgenstein adopted.
