Note 93 — LECTURE VI SUBCONSCIOUS PROCESSES

The mechanism is probably not quite so simple as this, probably past visual perceptions of self and the environment took part, so that the vision was a fusion or composite of these older primary images and the secondary images. The principle of mechanism, however, would not be affected by this added element. Sidis (The Doctrine of Primary and Secondary Sensory Elements, Psych. Rev., January-March, 1908) has maintained that all hallucinations are the emerging of the secondary images of previous perceptions. If, on the other hand, the vision be interpreted as something fabricated by the subconscious process—as must be the case with some hallucinations—then this process must have been much more complicated than memory. Something akin at least to constructive imagination and intelligence that translated the experiences into visual terms.
