" Since the survival impulse in nature is transmuted into two different and contradictory spiritualized forms, which we may briefly designate as the will-to-live-truly and the will-to-power, man is at variance with himself. The power of the second impulse places him more fundamentally in conflict with his fellowman than democratic liberalism realizes. "
