Abstract

Heraclitus said: "Wisdom is one thing: to know the gnome, the thought, by which all things are guided through all." Heidegger has said: "To think is to confine yourself to a single thought that one day stands still like a star in the world’s sky." Hegel portrayed the history of philosophy as the development of one single thought, which he expressed throughout a lifetime of philosophical genius: the speculative concept of self-consciousness, the identity of subject and object, of differents and opposites.
