Consciousness and Unconsciousness
Consciousness is one of the most basic concepts of psychology (as I understand psychology). No other psychological phenomena exist unless the person is conscious, at least to some degree.
The words consciousness and awareness are often used interchangeably, and I will use them this way also. Arousal and alertness are two other words often used as meaning the same thing as consciousness.
Short idea (17): An agitated, angry moment; an ecstatic, happy feeling; an itch in the right knee; a dream of a red fox walking in the snow; a thought of tomorrow's barbecue — all are made of the same "stuff." There is a common denominator.
Short idea (21): Everything passes including the awareness that everything passes.
Short idea (190): Knowledge and Power:
The Intellect thinks: "Knowledge is power."
The Imagination, when it experiences Self-Knowledge in itself or in others, thinks: "Super-Power!"
When the Imagination experiences Consciousness, it thinks: "Magic" or "God-like" or even "All-Powerful" ("Omnipotent") and "All-Knowing" ("Omniscient").
[This observations grew out my wife, Adelle Hersh's, thought that it is both a blessing and responsibility to have self-knowledge.]
