The dream state and the experiences thence derived are subjects for psychological science to investigate. The experiences allotted by du Maurier to "Peter Ibbetson" are not altogether fantastic and unwarranted, as the records of somnambulism and hypnotism abundantly prove. When we remember that nothing deserving the name of Psychology or Psychic Science exists in the western world to-day, we need not wonder why men eminent for investigations in other departments prove themselves novices and dogmatists here. The folklore, the traditions, and the mythology of dreams would form a very interesting subject for discussion. It is true that the literature of the subject is fantastic, mixed with fable and often altogether unreliable; but these difficulties offer no more formidable bar to scientific investigation than many another problem already classified and formulated for systematic study. I know a lady of very superior ability, the mother of a prominent jurist, who all her life has had distinct premonitions of many calamities and coming events, and there are those who dream true in every community. Fantasies, nightmare, dreams from indigestion and delirium, form a separate class where the dreamer is entangled in the meshes of the bodily functions. Here fasting, either voluntary or enforced, comes in, and drugs known to the remotest times are found to promote and to determine the character of dreams. There are furthermore processes of mental gymnastics whereby the thinker withdraws himself from the bodily avenues of sense and functions at will on the subjective plane of being. "When then," said Socrates, in the _Phaedo_, "does the soul light on the truth? for when it attempts to consider anything in conjunction with the body, it is plain that it is led astray by it." "And surely," he continues, "the soul reasons best when none of these things disturb it, neither hearing, nor sight, nor pain, nor pleasure of any kind, but it retires as much as possible _within itself_, _taking leave of the body_, and as far as it can, not communicating or being in contact with it, _it aims at the discovery of that which is_." I hold that the most valuable triumphs of science in the future lie in the realm of psychology, and that by no means the least important contribution in this direction will come from the study of Folklore, of which belief in the separable soul, and the phenomena and universality of the dream state must form a very important part. One final consideration is suggested not without some degree of hesitation and diffidence. If there be a soul in man destined to continued existence, and if in any case perfection is the goal of evolution as formulated by Herbert Spencer for a future residue of the human race, then this soul in its essential elements is without beginning in time.
