 History of Western Philosophy

In spite of Principia Mathematica, The Analysis of Mind and other land- 

 marks, this history may prove to be the crowning achievement of one of 

 the greatest intellects of our day. 



"It is certain of a very wide audience, and is, in my opinion, just the 

 kind of thing people ought to have to make them understand the past. . . . 

 It may be one of the most valuable books of our time. . . ." DR. G. M. 

 TREVELYAN. 



"Bertrand Russell's remarkable book is, so far as I am aware, the first 

 attempt to present a history of Western philosophy in relation to its 

 social and economic background. As such, and also as a brilliantly 

 written expose of changing philosophical doctrines, it should be widely 

 read." DR. JULIAN HUXLEY. 



My Philosophical Development

In this book Bertrand Russell gives an account of his philosophical 

 development from crude adolescent attempts at the age of 15 down to 

 the present day. He tells of his Hegelian period during the years 1894-8, 

 and includes hitherto unpublished notes for a Hegelian philosophy of 

 science. He deals next with the two-fold revolution involved in his 

 abandonment of idealism and adoption of a mathematical logic founded 

 upon that of Peano. After two chapters on Principia Mathematica, he 

 passes to the problems of perception as dealt with in Our Knowledge of 

 the External World. There is a chapter on "The Impact of Wittgenstein" 

 in which he examines what he now thinks must be accepted and what 

 rejected in that philosopher's work. He notes the changes from earlier 

 theories required by the adoption of William James's view that sensation 

 is not essentially relational and is not per se a form of knowledge. In 

 an explanatory chapter, he endeavours to remove misconceptions of 

 and objections to his theories as to the relation of perception to scientific 

 knowledge. The book concludes with a reprint of some recent articles 

 on modern Oxford philosophy. 



Such a survey as this, by one of the world's leading thinkers, of nearly 

 seventy years of his own philosophical work, is clearly as important as 

 it is fascinating. It is a masterpiece of philosophical autobiography.
