Part 2 (1/2)

_Percipient._--The correlative term to Agent; the person on whose mind the telepathic impact falls; or, more generally, the person who perceives any motor or sensory impression.

_Phantasm and Phantom._--Phantasm and phantom are, of course, mere variants of the same word; but since phantom has become generally restricted to _visual_ hallucinations, it is convenient to take phantasm to cover a wider range, and to signify any hallucinatory sensory impression, whatever sense--whether sight, hearing, touch, smell, taste, or diffused sensibility--may happen to be affected.

_Phantasmogenetic centre._--A point in s.p.a.ce apparently modified by a spirit in such a way that persons present near it perceive a phantasm.

_Phobies._--Irrational restricting or disabling preoccupations or fears; _e.g._, _agoraphobia_, fear of open s.p.a.ces.

_Photism._--See _Secondary sensations_.

_Point de repere._--Guiding mark. Used of some (generally inconspicuous) real object which a hallucinated subject sometimes sees as the nucleus of his hallucination, and the movements of which suggest corresponding movements of the hallucinatory object.

_Polyzoism._--The property, in a complex organism, of being composed of minor and quasi-independent organisms. This is sometimes called ”colonial const.i.tution,” from animal _colonies_.

_Possession._--A developed form of motor automatism, in which the automatist's own personality disappears for a time, while there appears to be a more or less complete subst.i.tution of personality, writing or speech being given by another spirit through the entranced organism.

_Post-hypnotic._--Used of a suggestion given during the hypnotic trance, but intended to operate after that trance has ceased.

_Precognition._--Knowledge of impending events supernormally acquired.

_Premonition._--A supernormal indication of any kind of event still in the future.

_*Preversion._--A tendency to characteristics a.s.sumed to lie at a further point of the evolutionary progress of a species than has yet been reached; opposed to reversion.

_*Promnesia._--The paradoxical sensation of recollecting a scene which is only now occurring for the first time; the sense of the _deja vu_.

_*Psychorrhagy._--A special idiosyncrasy which tends to make the phantasm of a person easily perceptible; the breaking loose of a psychical element, definable mainly by its power of producing a phantasm, perceptible by one or more persons, in some portion of s.p.a.ce.

_*Psychorrhagic diathesis._--A habit or capacity of detaching some psychical element, involuntarily and without purpose, in such a manner as to produce a phantasm.

_Psycho-therapeutics._--”Treatment of disease by the influence of the mind on the body.” (Tuke's _Dict._)

_Reciprocal._--Used of cases where there is both agency and percipience at each end of the telepathic chain, so that A perceives P, and P perceives A also.

_*Retrocognition._--Knowledge of the past, supernormally acquired.

_Secondary personality._--It sometimes happens, as the result of shock, disease, or unknown causes, that an individual experiences an alteration of memory and character, amounting to a change of personality, which generally seems to have come on during sleep. The new personality is in that case termed _secondary_, in distinction to the original, or _primary_, personality.

_Secondary sensations_ (_Secunddrempfindungen_, _audition coloree_, _sound-seeing_, _synaesthesia_, _etc._).--With some persons every sensation of one type is accompanied by a sensation of another type; as for instance, a special sound may be accompanied by a special sensation of colour or light (_chromatisms_ or _photisms_). This phenomenon is a.n.a.logous to that of _number-forms_,--a kind of diagrammatic mental picture which accompanies the conception of a progression of numbers.

See Galton's _Inquiries into Human Faculty_.

_Sh.e.l.l-hearing._--The induction of hallucinatory voices, etc., by listening to a sh.e.l.l. a.n.a.logous to crystal-gazing.

_Stigmatisation._--The production of blisters or other cutaneous changes on the hands, feet, or elsewhere, by suggestion or self-suggestion.

_Subliminal._--Of thoughts, feelings, etc., lying beneath the ordinary _threshold_ (_limen_) of consciousness, as opposed to _supraliminal_, lying _above_ the threshold.

_Suggestion._--The process of effectively impressing upon the subliminal intelligence the wishes of some other person. _Self-suggestion_ means a suggestion conveyed by the subject himself from one stratum of his personality to another, without external intervention.
