Quotes About 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.

It was all very well going on about pure logic and how the universe was ruled by logic and the harmony of numbers, but the plain fact of the matter was that the Disc was manifestly traversing space on the back of a giant turtle and the gods had a habit of going round to atheists' houses and smashing their windows.

To make music means to express human intelligence by sonic means.

The principles of logic and mathematics are true simply because we never allow them to be anything else.

Atlantis: Fabled. Mystical. Golden. Mysterious. Glorious and magical. There are those who claim that it never was. But then there are also those who think they are safe in this modern world of technology and weapons. Safe from all the ancient evils.

I didn't plan on falling in love with you, and I doubt if you planned on falling in love with me. But once we met, it was clear that neither of us could control what was happening to us. We fell in love, despite our differences, and once we did, something rare and beautiful was created. For me, love like that has happened only once, and that's why every minute we spent together has been seared in my memory. I'll never forget a single moment of it.

The only rule was that the stuff had to be funny and pretty short. To me, the quintessential Army Man joke was one of John Swartzwelder's: 'They can kill the Kennedys. Why can't they make a cup of coffee that tastes good?' It's a horrifying idea juxtaposed with something really banal-and yet there's a kind of logic to it. It's illuminating because it's kind of how Americans see things: Life's a big jumble, but somehow it leads to something I can consume. I love that.

Mankind has moved away from the heart of the world to the logic of the mind, and their belief is in the chemist, the physicist, and the mathematician. Science has proven to them that all this ancient belief in ceremony is simply ignorance.

My brother used to say that when you deal with women, it's difficult to remove emotions from an argument. I never really knew what he meant.

Man has been condemning women. Perhaps there is a reason; perhaps he was aware of some superiority in woman - the superiority of love. No logic can be higher than love, and no mind can be higher than the heart. But the mind can be very murderous; the mind can be very violent, and that's what the mind has done for centuries. Man has been beating women, repressing women, condemning women.

I tended to be more a romantic than a realist, and chose blind faith over cold logic.
