Logic
Logic (from the Ancient Greek: λογική, translit. logikḗ), originally meaning "the word" or "what is spoken", but coming to mean "thought" or "reason", is a subject concerned with the most general laws of truth, and is now generally held to consist of the systematic study of the form of valid inference. A valid inference is one where there is a specific relation of logical support between the assumptions of the inference and its conclusion. (In ordinary discourse, inferences may be signified by words like therefore, hence, ergo, and so on.)
Logic
Logic is a feeble reed, friend. "Logic" proved that airplanes can't fly and that H-bombs won't work and that stones don't fall out of the sky. Logic is a way of saying that anything which didn't happen yesterday won't happen tomorrow.
Robert A. Heinlein, Glory Road, (1967), Ch. 5.
Logic
No, no, you're not thinking; you're just being logical.
Attributed to Niels Bohr in: William Glen (1994) The Mass-Extinction Debates: How Science Works in a Crisis. p. 62
Logic
It is by logic that we prove, but by intuition that we discover. To know how to criticize is good, to know how to create is better.
Henri Poincaré, Science and Method (1908) Part II. Ch. 2 : Mathematical Definitions and Education, p. 129
