The Blue and Brown Books (1998)

Second Hand

Excellent Condition

These works, as the subtitle makes clear, are unfinished sketches for Philosophical Investigations, possibly the most important & influential philosophical work of modern times.

The Blue Book is a set of notes dictated to Witgenstein's Cambridge students in 1933-34: the Brown Book was a draft for what eventually became the growth of the 1st part of Philosophical Investigations. This book reveals the germination & growth of the ideas which found their final expression in his later work.

It's indispensable therefore to students of Witgenstein's thought & to all those who wish to study at 1st-hand the mental processes of a thinker who fundamentally changed the course of modern philosophy.
