The totally robotized Rationalist, the one whose nervous system has stopped growing entirely, can be recognized by two signs: He or she is constantly trying to prove that much of the daily experience of the rest of humanity is “delusion,” “hallucination,” “group hallucination,” “mass hallucination,” “mere coincidence,” “sheer coincidence,” or “sloppy research.” And he or she never thinks that any of his or her own experience would fit into any of those categories.
