There are multiple classic books of Marxist Critique on Idealism in the 19th and the beginning of the 20th century, but I have never seen one about the later philosophies such as Existentialism, Structuralism, Post-structuralism, etc…
Is there an author that has already given the Marxist point of view regarding those philosophies?
no problem. I didn’t knew him before too, bc he’s from India.
