perceptic (sense message) errors in the organic sphere are caused by psycho-somatic errors.
    Glasses are seen on noses everywhere around, even on children. The majority of these spectacles are perched on the face in an effort to correct a condition which the body itself is fighting to uncorrect again. Eyesight, when the stage of glasses is entered (not because of glasses), is deteriorating on the psycho-somatic principle. And this observation is about as irresponsible as a statement that when apples fall out of trees they usually obey gravity. One of the incidental things which happen to a clear is that his eyesight, if it had been bad as an aberree, generally improves markedly, and with some slight attention will recover optimum perception in time. (Far from an optician’s argument against dianetics, this assures rather good business, for clears have been known, at treatment’s end, to have to buy, in rapid succession, five pairs of glasses to compensate adjusting eyesight; and many aberrees, cleared late in life, settle down ocularly at a maximum a little under optimum.) The eyesight was reduced in the aberree on an organic basis by his aberrations so that the perceptic organ itself was reduced from optimum operating function. With the removal of aberrations, repeated tests have proven that the body makes a valiant effort to reconstruct back to optimum.
    Hearing, in addition to other perceptics, varies organically over a wide range. Calcium deposits, for instance, can make the ears “ring” incessantly. The removal of aberrations permits the body to readjust toward its reachable optimum, the calcium deposit disappears, and the ears stop ringing. But far and beyond this very specific case, there are great differences in hearing on the organic basis. Organically as well as aberrationally, hearing can become remarkably extended or closely inhibited so that one person may hear footsteps a block away as a normal activity and another would not hear a bass drum thundering on the porch.
    That the various perceptions differ widely from individual to individual on an aberrational and psycho-somatic basis is the least of the discoveries outlined here. Ability to recall is far more fantastic in its variation from person to person.

    An entirely new recall process which was inherent in the mind but which had not been noticed came to light in the process of observing clears and aberrees. This recall process is possible in only a small proportion of aberrees in its fullest sense. It is standard, however, in a clear. Naturally, no intimation is made here that the scholars of past ages have been unobservant. We are dealing here with an entirely new and hitherto non-existent object of inspection, the clear. What a clear can do easily, quite a few people have, from time to time, been partially able to do in the past.
    An inherent, not a taught, ability of the remembering mechanisms of the mind can be termed, as a technical word of dianetics, returning. It is used in its dictionary sense, with the addition of the fact that the mind has it as a normal remembering function, as follows: the person can “send” a portion of his mind to a past period on either a mental or combined mental and physical basis and can re-experience incidents which have taken place in his past in the same fashion and with the same sensations as before. Once upon a time an art known as hypnotism used what was called “regression” on hypnotized subjects, the hypnotist sending the subject back, in one of two ways, to incidents in his past. This was done with trance techniques, drugs and considerable technology.
    The hypnotic subject could be sent back to a moment “entirely” so that he gave every appearance of being the age to which he was returned with only the apparent faculties and recollections he had at that moment: this was called “revivification” (re-living). “Regression”
    was a technique by which part of the individual’s self remained in
