Ever since Engels' arrival in London in 1870, he was keen to write a comprehensive work on science and dialectical materialism. The notes and studies for such a work make up the present volume, originally published in 1925. It is an essential read for all those who want to develop a deeper understanding of Marxist philosophy.
