1. a departure from rational thought or behavior. From the Latin, aberrare, to wander from; Latin, ab, away, errare, to wander. It means basically to err, to make mistakes, or more specifically to havefixed ideas which are not true. The word is also used in its scientific sense. It means departure from a straightline. If a line should go from A to B, then if it is aberrated it would g o from A to some other point, to some other point, to some other point, to some other point, to some other point, and finally arrive at B. Taken in its scientific sense, it would also mean the lack of straightness or to see crookedly as, in example, a man sees a horse but thinks he sees an elephant. Aberrated conduct would be wrong conduct, or conduct not supported by reason. Aberration is opposed to sanity, which would be its opposite. 2. Aberration depends upon uncertainty. —LRH, 8-8008 —Scientology 8-8008 Glossary Final approval c. 3 Mar 1990
