Two methods are available—the educational and the biochemical. We can take adults and children as they are and give them a much better training than we are giving them now. Or, by appropriate biochemical methods, we can transform them into superior individuals. If these superior individuals are given a superior education, the results will be revolutionary. They will be startling even if we continue to subject them to the rather poor educational methods at present in vogue. Will it in fact be possible to produce superior individuals by biochemical means? The Russians certainly believe it. They are now halfway through a Five Year Plan to produce “pharmacological substances that normalize higher nervous activity and heighten human capacity for work.” Precursors of these future mind improvers are already being experimented with. It has been found, for example, that when given in massive doses some of the vitamins—nicotinic acid and ascorbic acid for example—sometimes produce a certain heightening of psychic energy. A combination of two enzymes—ethylene disulphonate and adenosine triphosphate, which, when injected together, improve carbohydrate metabolism in nervous tissue—may also turn out to be effective.

Meanwhile good results are being claimed for various new synthetic, nearly harmless stimulants. There is iproniazid, which, according to some authorities, “appears to increase the total amount of psychic energy.” Unfortunately, iproniazid in large doses has side effects which in some cases may be extremely serious. Another psychic energizer is an amino alcohol which is thought to increase the body’s production of acetylcholine, a substance of prime importance in the functioning of the nervous system. In view of what has already been achieved, it seems quite possible that, within a few years, we may be able to lift ourselves up by our own biochemical bootstraps.

In the meantime let us all fervently wish the Russians every success in their current pharmacological venture. The discovery of a drug capable of increasing the average individual’s psychic energy, and its wide distribution throughout the U.S.S.R., would probably mean the end of Russia’s present form of government. Generalized intelligence and mental alertness are the most powerful enemies of dictatorship and at the same time the basic conditions of effective democracy. Even in the democratic West we could do with a bit of psychic energizing. Between them, education and pharmacology may do something to offset the effects of that deterioration of our biological material to which geneticists have frequently called attention.

From these political and ethical considerations let us now pass to the strictly religious problems that will be posed by some of the new mind changers. We can foresee the nature of these future problems by studying the effects of a natural mind changer, which has been used for centuries past in religious worship; I refer to the peyote cactus of Northern Mexico and the Southwestern United States. Peyote contains mescaline—which can now be produced synthetically—and mescaline, in William James’ phrase, “stimulates the mystical faculties in human nature” far more powerfully and in a far more enlightening way than alcohol and, what is more, it does so at a physiological and social cost that is negligibly low. Peyote produces self-transcendence in two ways—it introduces the taker into the Other World of visionary experience, and it gives him a sense of solidarity with his fellow worshipers, with human beings at large and with the divine nature of things.

The effects of peyote can be duplicated by synthetic mescaline and by LSD (lysergic acid diethylamide), a derivative of ergot. Effective in incredibly small doses, LSD is now being used experimentally by psychotherapists in Europe, in South America, in Canada and the United States. It lowers the barrier between conscious and subconscious and permits the patient to look more deeply and understandingly into the recesses of his own mind. The deepening of self-knowledge takes place against a background of visionary and even mystical experience.

When administered in the right kind of psychological environment, these chemical mind changers make possible a genuine religious experience. Thus a person who takes LSD or mescaline may suddenly understand—not only intellectually but organically, experientially—the meaning of such tremendous religious affirmations as “God is love,” or “Though He slay me, yet will I trust in Him.”

It goes without saying that this kind of temporary self-transcendence is no guarantee of permanent enlightenment or a lasting improvement of conduct. It is a “gratuitous grace,” which is neither necessary nor sufficient for salvation, but which if properly used, can be enormously helpful to those who have received it. And this is true of all such experiences, whether occurring spontaneously, or as the result of swallowing the right kind of chemical mind changer, or after undertaking a course of “spiritual exercises” or bodily mortification.

Those who are offended by the idea that the swallowing of a pill may contribute to a genuinely religious experience should remember that all the standard mortifications—fasting, voluntary sleeplessness and self-torture—inflicted upon themselves by the ascetics of every religion for the purpose of acquiring merit, are also, like the mind-changing drugs, powerful devices for altering the chemistry of the body in general and the nervous system in particular. Or consider the procedures generally known as spiritual exercises. The breathing techniques taught by the yogi of India result in prolonged suspensions of respiration. These in turn result in an increased concentration of carbon dioxide in the blood; and the psychological consequence of this is a change in the quality of consciousness. Again, meditations involving long, intense concentration upon a single idea or image may also result—for neurological reasons which I do not profess to understand—in a slowing down of respiration and even in prolonged suspensions of breathing.

Many ascetics and mystics have practiced their chemistry-changing mortifications and spiritual exercises while living, for longer or shorter periods, as hermits. Now, the life of a hermit, such as Saint Anthony, is a life in which there are very few external stimuli. But as Hebb, John Lilly and other experimental psychologists have recently shown in the laboratory, a person in a limited environment, which provides very few external stimuli, soon undergoes a change in the quality of his consciousness and may transcend his normal self to the point of hearing voices or seeing visions, often extremely unpleasant, like so many of Saint Anthony’s visions, but sometimes beatific.

That men and women can, by physical and chemical means, transcend themselves in a genuinely spiritual way is something which, to the squeamish idealist, seems rather shocking. But, after all, the drug or the physical exercise is not the cause of the spiritual experience; it is only its occasion.

Writing of William James’ experiments with nitrous oxide, Bergson has summed up the whole matter in a few lucid sentences. “The psychic disposition was there, potentially, only waiting a signal to express itself in action. It might have been evoked spiritually by an effort made on its own spiritual level. But it could just as well be brought about materially, by an inhibition of what inhibited it, by the removing of an obstacle; and this effect was the wholly negative one produced by the drug.” Where, for any reason, physical or moral, the psychological dispositions are unsatisfactory, the removal of obstacles by a drug or by ascetic practices will result in a negative rather than a positive spiritual experience. Such an infernal experience is extremely distressing, but may also be extremely salutary. There are plenty of people to whom a few hours in hell—the hell that they themselves have done so much to create—could do a world of good.
