Quotes About Logic

Logic, n. The art of thinking and reasoning in strict accordance with the limitations and incapacities of the human misunderstanding. The basic of logic is the syllogism, consisting of a major and a minor premise and a conclusion - thus: Major Premise: Sixty men can do a piece of work sixty times as quickly as one man. Minor Premise: One man can dig a post-hole in sixty seconds; Therefore- Conclusion: Sixty men can dig a post-hole in one second.

We know that mathematicians care no more for logic than logicians for mathematics. The two eyes of science are mathematics and logic; the mathematical set puts out the logical eye, the logical set puts out the mathematical eye; each believing that it sees better with one eye than with two.

When you have to cast movies from a producer's standpoint - when you've been on the other side of casting sessions - you just get a completely different perspective on what that process is of getting a job for an actor. You realize how completely impersonal it is. If anything, I think it's made me a lot less sensitive.

Furthermore, they're going to attack you because you will be portrayed as not being credible: "You're an actor. What do you know?"
