The book "Hegel's Theory of Being, the Foundation of Historical Philosophy" is one of the most important books by Herbert Marcuse, with a valuable translation, introduction and commentary by the great translator, critic and researcher in the field of philosophy, Ibrahim Fathi. This book presents the unity of ontology, logic, and epistemology according to the great philosopher Hegel, the most important founder of German idealism in philosophy in the late eighteenth century AD, as a theoretical basis for the philosophy of history. Hegel's theory of being (ontology) differs from that of his predecessors.
