If meanings evolve on their own, and not through human agency, then is not all culture the result of the evolution of meanings, their random changes, and selective retention? The stage of mixed natural and cultural selection lasted for hundreds of thousands, perhaps millions of years; the stage of traditional choice lasted for thousands or tens of thousands of years. During this period, proto-human and early human populations self-reproduced by collective rather than individual action. Collective existence overshadowed the lives of individuals, their plans, and their destinies. Alfred Kroeber wrote that looking back over thousands of years of history, one might come to believe that hidden forces control individuals who have no influence over their lives:
“When one has acquired the habit of viewing the millennial sweeps and grand contours, and individuals have shrunk to insignificance, it is very easy to deny them consequential influence, even any influence—and therewith one stands in the gateway of belief in undefined immanent forces; a step more, and the forces have become mysterious” (Kroeber 1952, p. 9).
The difficult questions arise as to whether the individual is the origin of all action, whether he plays a significant role in the evolution of culture and whether man has free will at all.
As with natural selection, in the early stages of mixed selection, individuals were not its agents but merely inactive elements of self-reproducing populations—imitators and followers of first animal and then human traditions. A single human cannot reproduce himself. A human alone cannot give birth to or raise another human. He cannot even retain his common sense when alone. But as meanings accumulated in the course of mixed selection, the experience and sophistication of primitive communities increased, and with it the agency of individuals.
The increasing complexity of technologies, organizations and psychologies implies the emergence of consciousness and personality as its manifestation. Man becomes (self-)conscious and is a personality when he detaches himself from the community and at the same time searches for himself in a community of which he is a part. Michael Graziano writes that consciousness is a
