“Consciousness cannot be accounted for in physical terms. For consciousness is absolutely fundamental. It cannot be accounted for in terms of anything else.”

“If nothing exists, there can be no consciousness, a consciousness with nothing to be conscious of is a contradiction in terms. A consciousness conscious of nothing but itself is a contradiction in terms: before it could identify itself as consciousness, it had to be conscious of something. If that which you claim to perceive does not exist, what you possess is not consciousness.”

“The word 'God' is used in most cases as by no means a term of science or exact knowledge, but a term of poetry and eloquence, a term thrown out, so to speak, as a not fully grasped object of the speaker's consciousness — a literary term, in short; and mankind mean different things by it as their consciousness differs.”

“Rather than thinking in terms of good and bad, it is more helpful to think in terms of conscious and unconscious, aware, and unaware.”

“Defined in psychological terms, a fanatic is a man who consciously overcompensates a secret doubt.”

“Thinking is only a small aspect of consciousness. Thought cannot exist without consciousness, but consciousness does not need thought”
