Wittgenstein is a notoriously difficult philosopher, and anyone approaching his work will inevitably ask themselves the question: Is it going to be worthwhile?  It’s a common problem, of course. Do I really want to set aside the enormous amount of time and effort that it will take to understand Heidegger, or Derrida, or Deleuze?  Often the answer is no (and for good reason).  Part of what convinced me early on that Wittgenstein would be worth the effort was the portrait of Wittgenstein that emerges in Malcolm’s memoir: a man of fierce, extraordinary intelligence who was driven by the very deepest questions of human life.”
