Quotes About Logic

I end with a word on the new symbols which I have employed. Most writers on logic strongly object to all symbols. ...

The professor husband of a friend of mine has likened children to the insane. I often think of it. He says that children live on the edge of madness, that their behavior, apparently unmotivated, shares the same dream logic as crazy people's.

Stories are there to be told, and each story changes with the telling. Time changes them. Logic changes them. Grammar changes them. History changes them. Each story is shifted side-ways by each day that unfolds. Nothing ends. The only thing that matters, as Faulkner once put it, is the human heart in conflict with itself. At the heart of all this is the possibility, or desire, to create a piece of art that talks to the human instinct for recovery and joy.

Poets often describe love as an emotion that we can't control, one that overwhelms logic and common sense. That's what it was like for me. 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.

In every enterprise ... the mind is always reasoning, and, even when we seem to act without a motive, an instinctive logic still directs the mind.

In laying hands upon the sacred ark of absolute permanency, in treating the forms that had been regarded as types of fixity and perfection as originating and passing away, the Origin of Species introduced a mode of thinking that in the end was bound to transform the logic of knowledge, and hence the treatment of morals, politics, and religion.

This is the perpetual and pitiful tragedy of the practical man in practical affairs. He always begins with a flourish of contempt for what he calls theorizing and what people who can do it call thinking. He will not wait for logic-that is, in the most exact sense, he will not listen to reason. It will therefore appear to him an idle and ineffectual proceeding to say that there is a reason for his present failure. Nevertheless, it may be well to say it, and to try and make it clear even to him.
