Lessons on the Philosophy of Life (1899) Book

A very concise and easy-to-read guide for understanding the theory of dialectical materialism. Hegel will no longer seem that intimidating.

I think it was Trotsky who observed that a good approach towards understanding a theory - even a complicated mathematical theory - is to analyze its history, how that theory came into being. This is what Engels does here for dialectical materialism. So why is the title about Feuerbach then?, you may ask. Simply because his materialism is an important step away from Hegel's idealism, as it stands midway between the latter and Marx.
