What is the epochal, national and class nature of philosophy ?

Philosophy does not stand outside its time; it is the knowledge of the substance of its time.

Every man is the spawn of his age. Philosophy, too, is its age grasped in thought.

Any true philosophy is the essence of the spirit of its own age.

2) The Nationality of Philosophy

"That a cultured people should have no metaphysics is like a temple, otherwise richly adorned, but without a supreme god."

3),, Classes of Philosophy

Philosophy is classless; truth is classless, and what is classless is not truth. For example, in dialectics, we have not heard of "proletarian dialectics" and "bourgeois dialectics"; for example, there is no distinction between "proletarian materialism" and "bourgeois materialism" in materialism. For example, materialism does not distinguish between "proletarian materialism" and "bourgeois materialism".
