The chief distinction between primitive and modern man lies in the consideration that in the first case the blunder is inevitable, in the latter case the remedy lies to hand. How could primitive man be aware of the real connection between the use of certain drugs or herbs and an excitation or depression of the activities
of the nervous system? He does observe consequences, but he is quite ignorant of causes. Even to-day their full consequences are unknown; and it is absurd to expect that savage humanity should have been better informed. And even when a more rational theory exists, the practice persists under various forms. This is a principle that receives vivid illustration from the history of religions. The modern believer in mystical states of consciousness no longer advocates the use of drugs, and even fasting is going out of fashion. But we still have a continuation of the primitive practice in the shape of insistence on the cultivation of abnormal frames of mind if we are to experience a consciousness of communion with an alleged supersensible reality. That is, we are to achieve by a mental discipline what the savage or the medieval monk achieved by coarser and more obvious methods. To withdraw the mind from the normal influence of everyday life is to expose it to the play of hallucination and delusion. There is really no vital difference between unhealthy, solitary brooding on a given subject and drugging the mind with hashish. This class of modern mystic is one with the savage in an inability to recognise that the illumination is the product of the discipline, not the mere condition of its possession. Between the drug of the savage, the fasting and self-torture of the medieval monk and the prayerful meditation of the modern mystic, the difference is only that of changed times and altered conditions. The method is the same throughout.
The truth of this has been well put by Tylor:—
"The religious beliefs of the lower races are in no small measure based on the evidence of visions and
dreams, regarded as actual intercourse with spiritual being. From the earliest stages of culture we find religion in close alliance with ecstatic physical conditions. These are brought on by various means of interference with the healthy action of body and mind, and it is scarcely needful to remind the reader that, according to philosophic theories antecedent to those of modern medicine, such morbid disturbances are explained as symptoms of divine visitation, or at least of superhuman spirituality. Among the strongest means of disturbing the functions of the mind so as to produce ecstatic vision, is fasting, accompanied, as it usually is, with other privations, and with prolonged solitary contemplation in the desert or in the forest. Among the ordinary vicissitudes of savage life, the wild hunter has many a time to try involuntarily the effects of such a life for days together, and under these circumstances he soon comes to see and talk with phantoms which are to him invisible spirits. The secret of spiritual intercourse thus learnt, he has thence-forth but to reproduce the cause in order to renew the effects."[22]
As a means, then, of strengthening and perpetuating a consciousness of intercourse with the spiritual world, we have to reckon with, not merely the accidental occurrence of abnormal nervous conditions, but with their deliberate cultivation. The practice is world-wide, and persists in some form or other in all ages. Thus we find the Australians and many tribes of North American Indians use tobacco for this purpose. In Western Siberia a species of fungi, the 'fly Agaric,' so called because it is often steeped and the solution used
to destroy house flies, is used to produce religious ecstasy. Its action on the muscular system is stimulatory, and it greatly excites the nervous system.[23] An early Spanish observer says of the ancient Mexicans that they used a kind of mushroom, "which are eaten raw, and on account of being bitter, they drink after them, or eat with them a little honey of bees, and shortly after they see a thousand visions."[24] The mushroom was called the "bread of the gods." The Californian Indians give children tobacco, in order to receive instruction from the resulting visions. North American Indians held intoxication by tobacco to be supernatural ecstasy, and the dreams of men in this state to be inspired. The Darien Indians use the seeds of the Datura Sanguinea to induce visions. In Peru the priests prepared themselves for intercourse with the gods by partaking of a narcotic drink from the same plant. In Guiana the priest was prepared for his functions by fasting and flagellation, and was afterwards dosed with tobacco juice.[25] In India the Laws of Manu give explicit instructions as to the means of producing visions. Chief of these is the use of the 'Soma' drink. This is prepared from the flower of the lotus. The sap of this, says De Candolle, would be poisonous if taken in large quantities, but in small doses merely induces hallucination. Opium and hashish, a preparation of the hemp plant, have been in general use among Eastern peoples, as a means of producing ecstasy from remote antiquity. Opium, it is well known, produces an
extraordinary state of exaltation, intensifying the sense of one's personality, and inducing a pleasurable consciousness of mental strength and clarity. Under its influence, as De Quincey said, time lengthens to infinity and space swells to immensity.[26] Belladonna, a drug much used by medieval witches and sorcerers, has also had its vogue for purely religious purposes.
With the Greeks the laurel was sacred to Æsculapius. Those who wished to ask counsel of the god appeared before the altar crowned with laurel and chewing its leaves. Before prophesying, the Greek priestesses drank a preparation of laurel water. This contains, although it was, of course, unknown to them, two toxic substances—prussic acid and the volatile oil of laurel. The first would induce convulsions, the second, hallucinatory visions. The two combined were calculated to produce with both subject and observer a profound impression of spiritual illumination and possession.
It is unnecessary to multiply examples of the action of various drugs or herbs on the nervous system, or to cite the people who use them. Enough has been said to indicate how widespread is the practice, and the consequences are not hard to foresee. A very moderate development of intelligence would enable men to associate certain consequences with the use of particular drugs, but a very considerable amount of knowledge would be required to explain why these consequences were produced. In a social environment saturated with superstition the explanation lies ready to hand, and is accepted without question. A people that sees spiritual agency in all the familiar phenomena of nature are certainly not less likely to trace its influence in the mysterious and unaccountable effects of narcotics and stimulants. And each repeated experiment provides additional proof. Man thus not only believes himself to be surrounded by a spiritual world; he is actually able to enter into communication with it by methods that are defined in the clearest possible manner. Every repetition strengthens the delusion and
