People knew there were two ways of coming at truth. One was science, or what the Greeks called Logos, reason, logic. And that was essential that the discourse of science or logic related directed to the external world. The other was mythos, what the Greeks called myth, which didn't mean a fantasy story, but it was a narrative associated with ritual and ethical practice but it helped us to address problems for which there were no easy answers, like mortality, cruelty, the sorrow that overtakes us all that's part of the human condition. And these two were not in opposition, we needed both.

You are a white. The Imperial Wizard. Now, if you don't think this is logic you can burn me on the fiery cross. This is the logic: You have the choice of spending fifteen years married to a woman, a black woman or a white woman. Fifteen years kissing and hugging and sleeping real close on hot nights. With a black, black woman or a white, white woman. The white woman is Kate Smith. And the black woman is Lena Horne. So you're not concerned with black or white anymore, are you? You are concerned with how cute or how pretty. Then let's really get basic and persecute ugly people!

Anti-Semitism is best understood as a virus. It has no logic.

Hate needs no logic. It is a sickness of the soul.

The world of shapes, lines, curves, and solids is as varied as the world of numbers, and it is only our long-satisfied possession of Euclidean geometry that offers us the impression, or the illusion, that it has, that world, already been encompassed in a manageable intellectual structure. The lineaments of that structure are well known: as in the rest of life, something is given and something is gotten; but the logic behind those lineaments is apt to pass unnoticed, and it is the logic that controls the system.

The strength of the computer lies in its being a logic machine. It does precisely what it is programed to do. This makes it fast and precise. It also makes it a total moron; for logic is essentially stupid.

With the end of the nominating process, American politics leaves logic behind.

The main condition is that the spiritual ear should be open to overhear and patiently take in, and the will ready to obey that testimony which, I believe, God bears in every human heart, however dull, to those great truths which the Bible reveals. This, and not logic, is the way to grow in religious knowledge, to know that the truths of religion are not shadows, but deep realities.

There is no learned man but will confess be hath much profited by reading controversies,--his senses awakened, his judgment sharpened, and the truth which he holds firmly established. If then it be profitable for him to read, why should it not at least be tolerable and free for his adversary to write? In logic they teach that contraries laid together, more evidently appear; it follows then, that all controversy being permitted, falsehood will appear more false, and truth the more true; which must needs conduce much to the general confirmation of an implicit truth.

Hold fast to your beliefs and others will listen.

When I began my career as a cosmologist some twenty years ago, I was a convinced atheist. I never in my wildest dreams imagined that one day I would be writing a book purporting to show that the central claims of Judeo-Christian theology are in fact true, that these claims are straightforward deductions of the laws of physics as we now understand them. I have been forced into these conclusions by the inexorable logic of my own special branch of physics.

Chess is a unique battlefield for human minds and computers - human intuition, our creativity, fantasy, our logic, versus the brute force of calculation and a very small portion of accumulated knowledge infused by other human beings. So in chess we can compare these two incompatible things and probably make projections into our future. Is there danger that the human mind will be overshadowed by the power of computers, or we can still survive?

Murder is a horror, but an often necessary horror, never criminal, which it is essential to tolerate in a republican State. Is it or is it not a crime? If it is not, why make laws for its punishment? And if it is, by what barbarous logic do you, to punish it, duplicate it by another crime?

I read one or two other books which gave me a background in mathematics other than logic.

As a science, logic institutes an analysis of the process of the mind in reasoning, and investigating the principles on which argumentation is conducted; as an art, it furnishes such rules as may be derived from those principles, for guarding against erroneous deductions.

Certain issues in philosophy of science (having to do with observation and the definition of a theory's empirical import) had beenmisconstrued as issues in philosophy of logic and of language. With respect to modality, I hold the exact opposite: important philosophical problems concerning language have been misconstrued as relating to the content of science and the nature of the world. This is not at all new, but is the traditional nominalist line.

Some people will follow their minds without listening to their hearts, and others will follow their hearts without listening to their minds. This is why reason exists, for there to be balance between the heart and mind. We were not meant to follow the mind and ignore the heart. Instead, we were meant to follow the heart over the mind, but without completely abandoning logic. The middle way is the preferred way, and this path simply means to allow your heart to drive you, but do not forget to balance reason with your conscience.

Developing a compiler was a logical move; but in matters like this, you don't run against logic - you run against people who can't change their minds.

There's a Mr. Hyde for every happy Jekyll face, a dark face on the other side of the mirror. The brain behind that face never heard of razors, prayers, or the logic of the universe. You turn the mirror sideways and see your face reflected with a sinister left-hand twist, half mad and half sane.

Logic is the foundation of the certainty of all the knowledge we acquire.

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.

The deep paradox uncovered by AI research: the only way to deal efficiently with very complex problems is to move away from pure logic.... Most of the time, reaching the right decision requires little reasoning.... Expert systems are, thus, not about reasoning: they are about knowing.... Reasoning takes time, so we try to do it as seldom as possible. Instead we store the results of our reasoning for later reference.

I reached in experience the nirvana which is unborn, unrivalled, secure from attachment, undecaying and unstained.

People who are unable to use their hands skillfully for all kinds of work, will not become good thinkers and will behave awkwardly in life. It is not the head alone, but the whole human being that is a logician. Activities demanding manual and bodily skill, such as knitting, leads to the enhancement of the faculty of judgment. This faculty is actually developed least of all by exercises in logic.

It is all about numbers. It is all about sequence. It's the mathematical logic of being alive. If everything kept to its normal progression, we would live with the sadness-cry and then walk-but what really breaks us cleanest are the losses that happen out of order.

When money, instead of man, is at the center of the system, when money becomes an idol, men and women are reduced to simple instruments of a social and economic system, which is characterized, better yet dominated, by profound inequalities.

Does the logic connect? What are the range of probably outcomes? You want to figure out what those probabilities are and ideally be the House. It's fine to gamble, as long as you're the House.
