If you have become as discouraged as I have in the past in the struggle to decipher what philosophers are really up to, then this book will provide very helpful explanations. It is not a book that can be read through quickly, and it does require a fairly broad familiarity with the language of philosophy, however the effort to understand it is very well worth it. It is also not a book that reassures the kind of person who seeks to avoid personal responsibility and self-direction. It dissolves ordinary refuges of transcendently comforting words rather than promotes them. That is, this book is for fiercely independently-minded individuals. If you want to not be misled into the same mistakes philosophers have been making over the past two millennia, then this book is essential towards your quest.
