Leonardo Polo proposes a new interpretation of the history of philosophy, based on three remarkable periods: Athens, with Aristotle; Paris, With Thomas Aquinas; and Berlin, with Hegel. Taking advantage of the study of these three great thinkers, he has built the main outlines of his own philosophy, particularly his transcendental anthropology, amplifying remar-kably the transcendentals of classic philosphy. It also contains a new and very seminal interpretation of man. Finally, it supplies a reorientation of modern philosophy as a whole.
