While certain aspects of this book will be unintelligible to those lacking a technical education (like me) in American analytic philosophy--or to those who've never read Sartre, Hegel or Heidegger--the style of the book renders its main points interesting and comprehensible to an intelligent, thoughtful reader. Rorty's main points come through clearly and powerfully. The metaphor of philosophy as a mirror of nature--and the imperative need to move beyond this metaphor--is compelling and independent of the more analytically dense portions of the book. The full second half is fairly easy to follow for those who have more than a passing interest in philosophy.
But, this isn't it's main value. If you're daunted by the prospect of reading Derrida or Foucault--or even Sartre--parts of this book are the most honest and readable abridgments I've run across. As a lit grad student, I barely understood Derrida. Reading Rorty was like being given a magic key to unlock the inscrutable mysteries of continental postmodernism. Some find Rorty's style strained, but I think he's one of the most talented English-language stylists philosophy has known--perhaps second only to Jane Addams or William James.
This isn't light beach-reading material, but it is a great read for those at all interested in contemporary philosophy.
