Man has such a predilection for systems and abstract deductions that he is ready to distort the truth intentionally, he is ready to deny the evidence of his senses only to justify his logic.
Dostoevsky
The concept, the label, is perpetually hiding from us all the nature of the real.
Joyce Cary
Matter is less material and the mind less spiritual than is generally supposed. The habitual separation of physics and psychology, mind and matter is metaphysically indefensible.
Bertrand Russell
Our soul is cast into a body, where it finds number, time, dimension. Thereupon it reasons, and calls this nature necessity, and can believe nothing else.
Pascal
All that we see or seem
Is but a dream within a dream.
Edgar Allan Poe
