Leonardo Polo proposes a new interpretation of the history of philosophy, based on three remarkable periods: Athens, with Aristotle; Paris, With Thomas Aquinas; and Berlín, 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 remarkably 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.
