Abstract
Values provide evidence of spirit in human life. Spirit is a creative mental force for realizing values, a force which shows signs of a superindividual growth and decline, a life of its own. This paper documents the historic rise and decline of several waves of human creativity. I also consider possible factors that would account for the rise and fall: the presence of new material, social encouragement and/or patronage, temperamental egotism on the part of creators, the attraction of pioneering talent, or a collective or superindividual spirit.
