“The ability to perceive the world around one and the ability to draw accurate conclusions about it are, to all intents, the same thing.
“Glasses are a symptom of the decline of consciousness.” Hubbard, NSOL, 75/76
This is empiricism pure and invalidates the very essence of consciousness which is to be self aware and being self aware one has meta-perception and can think things over and evaluate. Evaluation is not part of perception. Drawing conclusions are processes of logic and reason, not perception.
Same with glasses they have nothing to do with consciousness. All these professors with glasses do not in the least suffer from lack of consciousness. Hubbard confuses awareness or sentience with consciousness as has been pointed out already.
