The capacity of the human mind for formulating and solving complex problems is very small compared with the size of the problems whose solution is required for objectively rational behavior in the real world.
Human beings, viewed as behaving systems, are quite simple. The apparent complexity of our behavior over time is largely a reflection of the complexity of the environment in which we find ourselves.
The human being cannot live in a condition of emptiness for very long: if he is not growing toward something, he does not merely stagnate; the pent-up potentialities turn into morbidity and despair, and eventually into destructive activities.
