That individual philosophical concepts are not anything capricious or autonomously evolving, but grow up in connection and relationship with each other; that, however suddenly and arbitrarily they seem to appear in the history of thought, they nevertheless belong just as much to a system as all the members of the fauna of a continent - is betrayed in the end also by the fact that the most diverse philosophers keep filling in a definite fundamental scheme of possible philosophies. Under an invisible spell, they always revolve once more in the same orbit; however independent of each other they may feel themselves with their critical or systematic wills, something within them leads them, something impels them in a definite order, one after the other - to wit, the innate systematic structure and relationship of their concepts. Their thinking is, in fact, far less a discovery than a recognition, a remembering, a return and a homecoming to a remote, primordial, and inclusive household of the soul, out of which those concepts grew originally: philosophizing is to this extent a kind of atavism of the highest order.
