By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature--for instance in a biological survey of evolution--we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.
