All our literature, music, art, drama, history, law, and legend has been wholly founded on our genetically engineered misperceptions. There are responses to changes at all levels in earth's partially open planetary system. Solar and other forms of radiation enter our atmosphere, as do asteroids containing ice, minerals, and perhaps the basis for life itself. Gravitational energy influences tides and is said to affect biological cycles. Daylight periods and climate do not obey human commands.
Human freedoms are in reality constrained by innumerable factors, and perhaps limited in scope.
Yet, in life, we can experience existential angst engendered by our perception of freedom as overwhelming. I agree with Morrison that uncertainty about the unknown, causal linkages, the future, reciprocal love, personal health and security combine with the human emotional makeup to engender to some aspects of our experience and imagination a 'value endowment' of extraordinary, supernatural qualities. The highly valued and greatly feared attain this special status. It must, therefore, have served our forefathers well, or the trait would have become vestigial or counterproductive and have been de-selected. It has become our Achilles heel, and is related to thinking with our loins - another naturally selected trait.
