SCN 8-8008: Perception

This paper presents Section 24 from the book SCIENTOLOGY 8-8008 by L. RON HUBBARD. The contents are from the original publication of this book by The Church of Scientology (1952).

The paragraphs of the original material (in black) are accompanied by brief comments (in color) based on the present understanding.  Feedback on these comments is appreciated.

The heading below is linked to the original materials.



The entire subject of perception is the subject of energy. As the preclear goes down the tone-scale, he is less capable of differentiation and is thus less and less capable of handling energy and is more and more subject to energy, until at last he will not emanate or handle energy. Even in the higher ranges of this descent his perception begins to diminish.

According to Kant, perception arises when sensations from external stimulus are assimilated into the mental matrix. By calling this a subject of energy, one is identifying perception as a “fast moving substance”. The clarity of perception exists at the upper end of the Tone scale. It starts to get blurred as a person moves down the Tone scale.

Perception is the basis of all ideas and knowledge. Therefore, as perception deteriorates, so do ideas and knowledge. As the person goes down the tone scale he is unable to see the gaps in reality as he fills them with expectations and assumptions. His logic takes short cuts and his ability to think suffers. He becomes increasingly subjective.

The rehabilitation of perception is essentially the rehabilitation of force. Force is rehabilitated by rehabilitating the control of energy. This is done by ARC processing and in many other ways. The chief way in which this is done is by establishing the preclear’s ability, by creative processing, to handle blackness.

The fundamental substance is force. Its movement is energy. Rehabilitation is learning to control this movement of force. This is done by bringing about consistency, harmony and continuity. The ultimate goal is to make the perception closely approximate the external stimulus.

An entire science called perceptics can easily be constructed and is mentioned in the original thesis (1948).

The rehabilitation of sight in the blind, hearing in the deaf, the ability to speak, anaesthesia of the body or body areas or the genital organs, depends upon the rehabilitation of the preclear’s ability to handle energy. Creative processing, with particular attention to handling blackness, is essential in this process.

General perception improves as one handles specific blackness in different areas. Blackness is occlusion.


Key Words: Perception, Blackness,



General perception improves as one handles specific blackness in different areas. As perception improves so do the ideas and knowledge. He can now see gaps in his reality and starts to fill them with actual observation. He becomes increasingly objective.

The ultimate goal is to make one’s perception closely approximate the external stimulus.
