Fact and Fable in Psychology

Astrology, Phrenology, Physiognomy, and Palmistry have in common a search for positive knowledge whereby to regulate the affairs of life, to foretell the future, to comprehend one's destiny and capabilities. They aim to secure success, or at least to be forearmed against failure by being forewarned. This is a natural, a practical, and in no essential way an occult desire. It becomes occult, or, more accurately, superstitious, when it is satisfied by appeals to relations and influences which do not exist, and by false interpretation of what may be admitted as measurably and vaguely true and about equally important. When not engaged in their usual occupation of building most startling superstructures on the most insecure foundations, practical occultists are like Dr. Holmes's katydid, "saying an undisputed thing in such a solemn way." They will not hearken to the experience of the ages that success cannot be secured nor character read by discovering their unreal or mystic stigmata; they will not learn from physiology and psychology that the mental capabilities, the moral and emotional endowment of an individual are not stamped on his body in such a way that they may be revealed by half an hour's use of the calipers and tape-measure; they will not listen when science and common sense unite in teaching that the knowledge of mental powers is not such as may be applied by rule of thumb to individual cases, but that, like much other valuable knowledge, it proceeds by the exercise of sound judgment, and must as a rule rest content with suggestive generalizations and imperfectly established correlations. An educated man with wholesome interests and a vigorous logical sense can consider a possible science of character and the means of aiding its advance without danger and with some profit. But this meat is sheer poison to those who are usually attracted to this type of speculations, while it offers to the unscrupulous charlatan a most convenient net to spread for the unwary. In so far as these occult mariners, the astrologists and phrenologists et id genus omne, are sincere, and in so far represent superstition rather than commercial fraud, they simply ignore, through obstinacy or ignorance, the lighthouses and charts and the other aids to modern navigation, and persist in steering their craft by an occult compass. In some cases they are professedly setting out, not for any harbor marked on terrestrial maps, but their expedition is for the golden fleece or for the apples of the Hesperides; and with loud-voiced advertisements of their skill as pilots, they proceed to form stock companies for the promotion of their several enterprises and to dispose of the shares to credulous speculators.

It would be a profitless task to review the alleged data of Astrology or Phrenology or Palmistry, except for the illustrations which they readily yield of the nature of the conceptions and of the logic which command a certain popular interest and acceptance. The interest in these notions is, as Mr. Lang argues about ghosts and rappings and bogles, in how they come to be believed, rather than in how much or how little they chance to be true. It must be remembered also that our present interest is in the occult factors of these composite systems; they each contain other factors,—in part incorporations of vague and distorted scientific truths, in part dogmatic overstatement of results of observation, which, if reduced to the proportions warranted by definite evidence, dissolve into insignificance or intangibility, in part plausible or specious argumentation, and in still greater part mere fanciful assertion. And if we proceed to examine the professed evidence for the facts and laws and principles (sit venia verbis) that pervade Astrology or Phrenology or Palmistry or dream-interpretation, or beliefs of that ilk, we find the flimsiest kind of texture, that will hardly bear examination, and holds together only so long as it is kept secluded from the light of day. Far-fetched analogy, baseless assertion, the uncritical assimilation of popular superstitions, a great deal of prophecy after the event (it is wonderful how clearly the astrologer finds the indications of Napoleon's career in his horoscope, or the phrenologist reads them in the Napoleonic cranial protuberances), much fanciful elaboration of detail, ringing the variations on a sufficiently complex and non-demonstrable proposition, cultivating a convenient vagueness of expression, together with an apologetic skill in providing for and explaining exceptions, the courage to ignore failure and the shrewdness to profit by coincidences and half-assimilated smatterings of science, and with it all an insensibility to the moral and intellectual demands of the logical decalogue,—and you have the skeleton, which, clothed with one flesh, becomes Astrology, and with another Phrenology, and with another Palmistry or Solar Biology or Descriptive Mentality or what not. Such pseudo-sciences thrive upon that widespread and intense craving for practical guidance of our individual affairs, which is not satisfied with judicious applications of general principles, with due consideration of the probabilities and uncertainties of human life, but demands an impossible and precise revelation. Not all that passes for, and in a way is knowledge, is or is likely soon to become scientific; and when a peasant parades in an academic gown the result is likely to be a caricature.
