The id is that very protohuman psychic core that our evolution has spent millions of years molding to fit the planetary environment. Its seeming unruliness deserves a deeper understanding…the id conserves from its long maturing process our treasury of ecological intelligence. Its intractability stems from its deeply ingrained resistance to all social forms that endanger the harmony of the human and the natural; its untamed selfishness represents a bond between psyche and cosmos whose distant origins reach back to the initial conditions of the Big Bang. Just as there is a wisdom of the body which often has a better sense of health than medical science, so too there may be a wisdom of the id that knows what sanity is better than any school of psychiatry whose standard of normality is essentially a defense of misconceived social necessity.
