The reasons that hallucinations take the -particular form they do lie partly in the physical nature of the world, but mostly in education and a familiarity with gods and religious history. But I do mean to suggest (1) that there are in the brain aptic structures for the very existence of such hallucinations, 20 Schreber, pp. 226, 332. 21 Ibid., p. 269. 22 J. Custance, Wisdom, Madness and Folly (New York: Pellegrini and Cudahy, 1952), p. 18. 417 S C H I Z O P H R E N I A (2) that these structures develop in civilized societies such that they determine the general religious quality and authority of such hallucinated voices, and perhaps organize them into hierarchies, (3) that the paradigms behind these aptic structures were evolved into the brain by natural and human selection during the early civilizing of mankind, and (4) are released from their normal inhibition by abnormal biochemistry in many cases of schizophrenia and particularized into experience.
