AUTHOR'S NOTE ON THE FOURTH EDITION This little book on Materialism and the Dialectical Method originated from lectures given under the auspices of the London District Committee of the Communist Party of Great Britain in 1950. That was a long time ago and a lot has been thought and written on the subject since then. I am glad that nevertheless it has continued to be found useful—though to try to make it so I have now had to revise it three times over. In these revisions I have changed as little as possible. In preparing this fourth edition I have made mostly only minor stylistic changes intended to render the meaning clearer and avoid misunderstandings. In particular I have left intact references to J. V. Stalin's booklet on Dialectical and Historical Materialism and Mao Tse-tung's lecture On Contradictions, both of which seem to me to remain worthy of quotation whatever may be objected against other words and deeds of their authors. The only substantial change I have made is in the reference to biology and the controversial theories of Trofim Lysenko in Chapter 7, where what I had written originally was obviously written in error. I would like to stress that this book has no pretentions to be anything more than "an Introduction". It is not a textbook of Marxist philosophy but an introduction to some key philosophical ideas of Marxism which it still remains for Marxists to work out, criticise and develop further. M.C. London, January 1968
