Logic is the art of going wrong with confidence.
Anonymous
Dependability, integrity, the characteristic of never knowingly doing anything wrong, that you would never cheat anyone, that you would give everybody a fair deal. Character is a sort of an all-inclusive thing. If a man has character, everyone has confidence in him. Soldiers must have confidence in their leader.
Omar Bradley
For generations, scientists and philosophers have tried to explain ordinary reasoning in terms of logical principles—with virtually no success. I suspect this enterprise failed because it was looking in the wrong direction: common sense works so well not because it is an approximation of logic; logic is only a small part of our great accumulation of different, useful ways to chain things together.
Marvin Minsky
Not knowing what one is looking for is pure agony. Too much analytical thinking, too much logic, too many meanings! Life has no logic, so why does there have to be logic to explain what it means? Also, what is logic? I think I may need to break away from analytical thinking; this is the cause of all my anxieties.
Gao Xingjian
So much of modern mathematical work is obviously on the border-line of logic, so much of modern logic is symbolic and formal, that the very close relationship of logic and mathematics has become obvious to every instructed student. The proof of their identity is, of course, a matter of detail: starting with premisses which would be universally admitted to belong to logic, and arriving by deduction at results which as obviously belong to mathematics, we find that there is no point at which a sharp line can be drawn, with logic to the left and mathematics to the right. If there are still those who do not admit the identity of logic and mathematics, we may challenge them to indicate at what point, in the successive definitions and deductions of Principia Mathematica, they consider that logic ends and mathematics begins. It will then be obvious that any answer must be quite arbitrary.
Bertrand Russell
We are not wrong, we are not wrong in what we are doing. If we are wrong, the Supreme Court of this nation is wrong. If we are wrong, the Constitution of the United States is wrong. And if we are wrong, God Almighty is wrong. If we are wrong, Jesus of Nazareth was merely a utopian dreamer that never came down to Earth. If we are wrong, justice is a lie, love has no meaning. And we are determined here in Montgomery to work and fight until "justice runs down like water, and righteousness like a mighty stream."
