You don’t need a Phd to read Marxist works, wtf you talking about?

Dilaectical Materialism is influenced by Hegel’s Dialectical Idealism, but rejects the majority of it as idealism. A good primer is Elementary Principles of Philosophy, by Georges Politzer, which goes over the history of Idealism, Dialectics, and Materialism, before showing how they gave way to Dialectical and Historical Materialism.

It requires reading to understand, but certainly no PhD!
