The Idea of Man: Concepts of Human Ontology

The Idea of Man presents a new ontology, or idea of human being, by developing the logic that naturally flows from that which is original, necessary, inherent and essential to this being - upright posture. The verticality of man, simply and mutely constituted by his innate 'uprightness', is taken as the ontological key to understanding the idea of man, the world of language and the very possibility of Being itself.
In this, the book conceives in unison both an Ontological Anthropology and an Anthropological Ontology.
