ABSTRACT
The human species is naturally governed biologically by the same laws as other forms of life; furthermore, the stability of its genetic constitution greatly limits its chances for progress through Darwinian evolution. But human beings are endowed with a spirit of adventure and fantasy that enables them to move into many different environments and to create innumerable social structures. Most human beings have some latitude in selecting the conditions under which they live. They move into environments or adopt customs that appeal to them, rather than merely accepting the conditions under which they have been placed by the accidents of life. Throughout history and prehistory humankind also has had to choose repeatedly between opposite tendencies which seem to be inherent in human nature. The spiritual and emotive quality of nature does not reside in brute facts but rather originates from the transmutation of these facts into new values by human imagination and fantasy.
