Logic is Marmite

Logic is like Marmite some people love it and, I'm afraid, some people hate it. It divides opinion. Here are a few thoughts on logic:

There's a mighty big difference between good, sound reasons and reasons that sound good
Burton Hillis

Logical errors are, I think, of greater practical importance than many people believe; they enable their perpetrators to hold the comfortable opinion on every subject in turn.
Bertrand Russell


Once master the machinery of Symbolic Logic, and you have a mental occupation always at hand, of absorbing interest, and one that will be of real use to you in any subject you may take up. It will give you clearness of thought—the ability to see your way through a puzzle—the habit of arranging your ideas in an orderly and get-at-able form—and, more valuable than all, the power to detect fallacies, and to tear to pieces the flimsy illogical arguments, which you will so continually encounter in books, in newspapers, in speeches, and even in sermons, and which so easily delude those who have never taken the trouble to master this fascinating Art.
Lewis Carroll


Logic is the art of going wrong with confidence
Joseph Wood Krutch


Better to be without logic than without feeling
Charlotte Brontë

Albert Einstein

Oscar Wilde

Logic: The art of thinking and reasoning in strict accordance with the limitations and incapacities of the human misunderstanding.
Ambrose Bierce
