This is a supplemental reading to assist with your understanding ...
This is a supplemental reading to assist with your understanding of dialectical materialism. I strongly suggest you read this with Socialism: Scientific and Utopian by Engels if you wish to have a conceptual understanding of dialectical materialism without going through massive tomes by other authors.
Stalin writes fairly straightforward, and he covers a basic introduction of what dialectical and historical materialism are and how they work.
