I agree that there is no doubt that mental illness is a phenomena. One could describe Modern America as an epidemic of mental illness. Except for a few diseases, schizophrenia, for example, the vast majority of mental issues are environmental, not genetic.
Apprentice Anon has written how Adam used reasoning (cause and effect) to determine that the problems experienced in the Garden of Eden was the responsibility of the Lord God. Adam has realized that if either the tree of knowledge of good and evil was not present or Eve was not created then the situation would never have occurred. The Lord God did not understand it as a matter of reasoning, nor should we expect reason from the lawgiver.
Understanding Adam's reasoning will allow us to resolve the issue of mental illness-all mental illness is a result of unnatural behavior- to wit, living in cites and being subjected to other human's behavior. By applying Adam's reasoning that without either the tree or the woman, the transgression could not have happened, likewise, without the city, mental illness would be unknown.
Human beings living in a lagoon without concern about how they look (anorexia), how they feel (depression), what they have (hoarding), what they do not posses (envy leads to crime) and what others think of them (paranoia, self esteem and resentment) could be described as paradise.
Fred writes that man is not the end or the goal of our existence and he also states that man is a bridge to the superman-the next step in our evolution-a being without the problems of modern man who will behave according to the dictates of Nature and his will to power.
Gentle Reader, judging by modern America, we can expect this evolution to be described as micro, not macro.
