Human nature is determined by the material conditions of a society, e.g. the relations of production, the productive forces, and the mode of production. It’s a historical development and doesn’t exist in a vacuum, neither does it float above us in the sky and beyond our comprehension. To understand human nature we must study how society reproduces itself, from the way our ape ancestors lived up to how human beings live now. Historical materialism is the method we should use to study human nature. We always had to produce in order to exist, however primitive those means of production may have been, and our labor has always been social, however primitive those means of communication were, such as language.

Stalin’s https://redsails.org/dialectical-and-historical-materialism/ is a necessary read for any ML who wants to advance the cause of communism in all aspects of our movement. I suspect that the “human nature” argument that the libs throw at us constantly is one of these aspect we need to understand thoroughly because they keep pushing it and without seeing the misanthropy underlying their logic, no progress can be achieve against “individualism.”
