ABSTRACT
The foregoing discussion of Shelley’s psychology, and especially of what was abnormal in it, would hardly be complete without some reference to the possibility of his having possessed what may be termed higher psychic powers. The whole subject is, of course, difficult, and this is not the place to embark on a long analysis of the general evidence for the existence of super-normal faculties. But, in view of the considerable researches that have been of late undertaken in this field, and of the general results that have been achieved, some mention of this aspect of Shelley’s genius is not inappropriate. We have noted in his private life the recurrence of certain ideas of persecution and of certain hallucinations. These things, like all other mental aberrations, 107require, as their necessary condition, some degree of dissociation of the various components of the mind. Just as the growth of a tumour indicates a certain autonomy of one portion of the body, so such phenomena as hallucination, double-personality, mediumistic trances, hysteria, and obsessions, indicate the autonomy of certain constituents of the mind or personality. But this capacity for decentralisation is not merely pathological in its effects ; the same partial suspension of the control normally exercised by the conscious mind may liberate either the repressed impulses of the hysterical patient or the latent divinations and intuitions which mark the genius or the mystic.
