The upshot of genetic studies leads in two (!) directions: a narrow path and a broad one. The narrow road heads toward simplistic, monogenic causes. It wants to pinpoint bits of tissue and correlate them with the vast complexity of psychic meanings. The folly of reducing mind to brain never seems to leave the Western scene. We can never give it up because it is so basic to our Western rationalist and positivist mind-set. The rationalist in the psyche wants to locate causes you can put your hands on and fix.
Machines provide the best models for meeting this desire. Take them apart, find their inner mechanisms, and then adjust their functioning by modifying their ratchets, enriching their fuel, greasing their connections. Henry Ford as father of American mental health. Result: Ritalin, Prozac, Zoloft, and dozens of other effective products for internal adjustments that we consume in abundance, millions of us, daily or twice daily. The simplistics of monogenic causes eventually leads to the control of behavior by drugs–that is, to drugged behavior.
Robert Plomin, on whose passionate, prolific, and perceptive writings this chapter has frequently relied, urgently warns against using genetics in a simplistic manner. He states: “Genetic effects on behavior are polygenic and probabilistic, not single gene and deterministic.” I gather from him a warning to psychiatry: Do not capsize your noble vessel under the weight of pharmaceutical, insurance company, and government gold, and do not set your compass toward Fantasy Island, where genetics will define “disease entities in psychiatry.” “We have learned little about the genetics of development [how genes act and interact over time] except to appreciate its complexity.” Therefore we can never arrive at that equation where one defective gene equals one clinical picture (except for true anomalies like Huntington’s chorea).
These warnings have little effect; simplistic thinking fulfills too many wishes. The heads of Henry Ford and Thomas Edison are carved into the Mount Rushmore of the mind. The monster of mechanism appears in every century of modern Western history and must be watched for by each generation–especially ours, when to hold out for “something else” besides nature or nurture means believing in ghosts or magic.
Ever since French rationalism of the seventeenth (Marin Mersenne, Nicolas de Malebranche) and eighteenth (Etienne de Condillac, Julien Offroy de La Mettrie) centuries and right through to the positivism of the nineteenth (Antoine Destutt de Tracy, Auguste Comte) in which all mental events were reduced to biology, a piece of the collective Western mind had been yolked like a dumb ox to the heavy tumbrel of French mechanistic materialism. It is astounding how people with such subtle taste as the French and with such erotic sensibility can go on and on contributing so much rationalist rigor mortis to psychology. Every import that arrives from France must be inspected for this French disease, even though it carries the fashionable label of Lacanism, Structuralism, Deconstruction, or whatever.
Today rationalism is global, computer-compatible every-where. It is the international style of the mind’s architecture. We cannot pin it to a particular flag, unless to the banners of the multinational corporation that can spend big bucks turning psychiatry, and eventually psychological thinking, and therefore soul control, toward monogenetic monotheism. One gene for one disorder: Splice the gene, teach it tricks, combine it, and the disorder is gone, or at least you don’t know you have it. The narrow path leads back to the thirties and forties of psychiatric history, though in a more refined manner and with better press releases. From 1930 into the 1950s, correlating specific brain areas with large emotional and functional concepts provided the rationale for the violence of psychosurgery and the lobotomizing of many a troubled soul at odds with circumstance.
The narrow path is yet more retro, going back to the skill analysis of Franz Josef Gall (M.D., Vienna, 1795), who settled in Paris and was much appreciated by the French. From him came the “evidence” that skull bumps and declivities could be correlated with psychological faculties (a system later called phrenology). Much as they are today, the faculties were given big names, such as memory, judgment, emotionalism, musical and mathematical talent, criminality, and so on. Refinement in methods over the years does not necessarily lead to progress in theorizing: 1795 or 1995–material location, and then reduction of psyche to location, prompts the enterprise.
The contrary direction to narrowing nature to brain simplistics is expanding nurture to a far more embracing notion of environment. If environment means literally what’s around, it must also mean whatever is around. This because the unconscious psyche selects quite arbitrarily among the stuff encountered every day in the environment. Tiny and trivial bits of information may have huge subliminal psychic effects, as the days’ residues in dreams show. We do dream of the damnedest things! Much of each day is never noticed or recalled, but the psyche picks up the environmental flotsam and delivers it to the dream. The dream–a processing plant recycling the environment, finding soul values in junk. The dream–an artist, appropriating images from the environment for recollection in tranquility.
Because we walk about in fields of psychic realities that influences our lives, we have to broaden the notion of environment in terms of “deep ecology,” the hypothesis that the planet is a living, breathing, and self-regulating organism. Since anything around can nourish our souls by feeding imagination, there is soul stuff out there. So why not admit, as does deep ecology, that the environment itself is ensouled, animated, inextricably meshed with us and not fundamentally separate from us?
The ecological vision restores to environment also the classical idea of providentia–that the world provides for us, looks out for us, even looks after us. It wants us around, too. Predators, tornadoes, and blackflies in June are only pieces of the picture. Just think of all that’s delicious and sweet-smelling. Do birds sing but for each other? This breathable, edible, and pleasant planet, invisibly serviced and maintained, keeps us all by means of its life-support system. Such would be an idea of nurture that is truly nurturing.
“Environment,” then, would be imagined well beyond social and economic conditions, beyond the entire cultural setting, to include every item that takes care of us every day: our tires and coffee cups and door handles and the book you are holding in your hands. It becomes impossible to exclude this bit of environment as irrelevant in favor of that bit as significant, as if we could rank world phenomena in order of importance. Important for whom? Our understanding of importance itself has to change; instead of “important to me,” think of “important to other aspects of the environment.” Does this item nurture what else is around, not merely us who are around? Does it contribute to the intentions of the field of which we are only one short-lived part?
As notions of environment shift, we notice environment differently. It becomes more and more difficult to make a cut between psyche and world, subject and object, in here and out there. I can no longer be sure whether the psyche is in me or whether I am in the psyche as I am in my dreams, as I am in the moods of the landscapes and the city streets, as I am in “music heard so deeply/That it is not heard at all, but you are the music/While the music lasts” (T.S. Eliot). Where does the environment stop and I begin, and can I begin at all without being in some place, deeply involved in, nurtured by the nature of the world?
