quite commonly does not understand the things which our philosophy very creditably explains. The two types of mind are different, and, as Professor James expresses it, "the scientific-academic mind and the feminine-mystical mind shy from each other's facts just as they fly from each other's temper and spirit."
Certain special influences combine with these fundamental differences of attitude to favor the spread of belief in the occult; and of these the character of the beliefs as of the believers furnishes some evidence. At various stages of the discussion I have referred to the deceptive nature of the argument by analogy; to the dominating sympathy with a conclusion, and the resulting assimilation and overestimation of apparent evidence in its favor; to the frequent failure to understand that the formation of valid opinion and the interpretation of evidence in any field of inquiry require somewhat of expert training and special aptitude, obviously so in technical matters, but only moderately less so in matters misleadingly regarded as general; to bias and superstition, to the weakness that bends easily to the influences of contagion, to unfortunate educational limitations and perversions, and, not the least, to a defective grounding in the nature of scientific fact and proof. The mystery attaching to the behavior of the magnet led Mesmer to call his curative influence "animal magnetism,"—a conception that still prevails among latter-day occultists. The principle of sympathetic vibration, in obedience to which a tuning-fork takes up the vibrations of another in unison with it, is violently transferred to imaginary brain vibrations and to still more imaginary telepathic currents. The X-ray and wireless telegraphy are certain to be utilized in corroboration of unproven modes of mental action, and will be regarded as furnishing the key to clairvoyance and rapport; just as well-known electrical phenomena have given rise to the notions of positive and negative temperaments and mediumistic polar attraction and repulsion. All this results from the unwarranted and absurd application of analogies; for analogies, even when appropriate, are little more than suggestive or corroborative of relations or conceptions which owe their main support to other and more sturdy evidence. Analogy under careful supervision may make a useful apprentice, but endless havoc results when the servant plays the part of the master.
No better illustrations could be desired of the effects of mental prepossession and the resulting distortion of evidence and of logical insight than those afforded by the career of Spiritualism and that of Christian Science. In both these movements the assimilation of a religious trend has been of inestimable importance to their dissemination. Surely it is not merely or mainly the evidences obtainable in the séance chamber, nor the irresistible accumulation of cures by argument and thought-healings, that account for the organized gatherings of Spiritualists and the costly temples and thriving congregations of Christ Scientist. It is the presentation of a practical doctrine of immortality and of the spiritual nature of disease in conjunction with an accepted religious system, that is responsible for these vast results. The "Key to the Scriptures" has immeasurably reinforced the "Science and Health," and brought believers to a new form of Christianity who never would have been converted to a new system of medicine presented on purely intellectual grounds. Rationality is doubtless a characteristic tendency of humanity, but logicality is an acquired possession, and one by no means firmly established in the race at large. So long as we are reproved by the discipline of nature, and that rather promptly, we tend to act in accordance with the established relations of things; that is rationality. But the recognition of the more remote connections between antecedent and consequent, and the development of habits of thought which shall lead to reliable conclusions in complex situations; and again, the ability to distinguish between the plausible and the true, the firmness to support principle in the face of paradox and seeming nonconformity, to think clearly and consistently in the absence of the practical reproof of nature—that is logicality. It is only as the result of a prolonged and conscientious training, aided by an extensive experience and by a knowledge of the historical experience of the race, that the inherent rational tendencies develop into established logical habits and principles of belief. For many this development remains stunted or arrested; and they continue as children of a larger growth, leaning much on others, rarely venturing abroad alone, and wisely confining their excursions to familiar ground. When they become possessed with the desire to travel among other cultures, their lack of appreciation of the sights which their journeys bring before them gives to their reports the same degree of reliability and value as attaches to the much ridiculed comments of the philistine nouveaux riches.
The survey of the modern occult makes it seem quite utopian to look forward to the day when the occult shall have disappeared, and the lion and the lamb shall feed and grow strong on the same nourishment. Doubtless new forms and phases of the occult will arise to take the place of the old as their popularity declines; and the world will be the more interesting and more characteristically a human dwelling-place for containing all sorts and conditions of minds. None the less, it is the plain duty and privilege of each generation to utilize every opportunity to dispel error and superstition, and to oppose the dissemination of irrational beliefs. It is particularly the obligation of the torch-bearers of science to illuminate the path of progress, and to transmit the light to their successors with undiminished power and brilliancy; the flame must burn both as a beacon-light to guide the wayfarer along the highways of advance, and as a warning against the will-o'-the-wisps that shine seductively in the by-ways. The safest and most efficient antidote to the spread of the pernicious tendencies inherent in the occult lies in the cultivation of a wholesome and whole-souled interest in the genuine and profitable problems of nature and of life, and in the cultivation with it of a steadfast adherence to common sense, that results in a right perspective of the significance and value of things. These qualities, fortunately for our forefathers, were not reserved to be the exclusive prerogative of the modern; and, fortunately for posterity, are likely to remain characteristic of the scientific and antagonistic to the occult.
THE PROBLEMS OF PSYCHICAL RESEARCH
I
The division of the sciences reflects the diversity of human interests; it represents the economical adaptation of organized thought to the conditions of reality; and it likewise recognizes the intrinsically and objectively distinct realms and aspects, in which and under which phenomena occur. It is obvious that the sciences were shaped by human needs; that physics and chemistry and geology and biology and psychology do not constitute independent departments of nature's régime, but only so many aspects of complex natural activities; that a cross-section of the composite happenings of a cosmic moment would reveal an endlessly heterogeneous concomitance of diverse forms of energy acting upon diverse types of material; that, as we confine our attention somewhat arbitrarily to one or another component of the aggregate, we become physicists, or chemists, or geologists, or biologists, or psychologists; that, indeed, Nature is all things to all men. There is, furthermore, a community of spirit between the several sciences, as there is a logical unity of method and purpose within the realm of each. However ignorant they may be of one another's facts, the chemist and the psychologist readily appreciate one another's purposes, and find a bond of sympathy in the pursuit of a commonly inspired though differently applied method. The search for objective truth, the extension of the realm of law and regularity, the expansion and organization of the army of facts constantly marshaled and reviewed and made ready for service, the ever widening development of principles and the furthering of a deeper insight into their significance,—these are ideals for the advancement of science, far easier of expression than of execution, but the clear and accepted formulation of which itself attests a highly developed stage of accurate thought. A clear-cut conception of the purposes and methods of scientific investigation and of the scope of the several sciences is a dearly bought product of generations of well-directed, as also of misdirected, effort. The path of progress leading to this achievement has been tortuous and indirect; there has been much expenditure of energy that resulted merely in marking time, in going through the movements of locomotion but with no advance, in following a false trail, or, through a loss of the sense of direction, in coming back after a circuitous march to an earlier starting-point.
