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.

I end with a word on the new symbols which I have employed. Most writers on logic strongly object to all symbols. ... I should advise the reader not to make up his mind on this point until he has well weighed two facts which nobody disputes, both separately and in connexion. First, logic is the only science which has made no progress since the revival of letters; secondly, logic is the only science which has produced no growth of symbols.

The Nazis played the same games against Jews that today’s left plays against 'Eurocentrism,' 'whiteness,' and 'logocentrism.' When you hear a campus radical denounce 'white logic' or 'male logic,' she is standing on the shoulders of a Nazi who denounced 'Jewish logic' and the 'Hebrew disease'...The white man is the Jew of liberal fascism.

In this world are very few things made from logic alone. It is illogical for man to be too logical. Some things we must just let stand. The mystery is more important than any possible explanation. The searcher after truth must search with humanity. Ruthless logic is the sign of a limited mind. The truth can only add to the sum of what you know, while a harmless mystery left unexplored often adds to the meaning of life. When a truth is not so important, it is better left as a mystery.

His musical inspiration operates in a world uncluttered by conventional bar lines, conventional chord changes, and conventional ways of blowing or fingering a saxophone. Such practical 'limitations' did not even have to be overcome in his music; they somehow never existed for him. Despite this - or more accurately, because of this - his playing has a deep inner logic. Not an obvious surface logic, it is based on subtleties of reaction, subtleties of timing and color that are, I think, quite new to jazz - at least they have never appeared in so pure and direct a form.

Clinging to any form of conservatism can be dangerous. Become too conservative and you are unprepared for surprises. You cannot depend on luck. Logic is blind and often knows only its own past. Logic is good for playing chess but is often too slow for the needs of survival.

I think every film is somehow a political film. You show a perspective and a world that has logic, and that logic is inserted into a political environment, and it means something. Yes, why not?

I hope you become comfortable with the use of logic without being deceived into concluding that logic will inevitably lead you to the correct conclusion.

Desperation precludes reflection. That is one of the reasons why smart people can get involved in very obviously unworkable relationships. Like addiction, that deep, Imago attachment is more powerful than logic, and in fact disables logic. So, any explanation or analysis or reflection on such a feeling is already many steps removed from the experience.

My life isn’t theories and formulae. It’s part instinct, part common sense. Logic is as good a word as any, and I’ve absorbed what logic I have from everything and everyone… from my mother, from training as a ballet dancer, from Vogue magazine, from the laws of life and health and nature.

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.

Logic is justly considered the basis of all other sciences, even if only for the reason that in every argument we employ concepts taken from the field of logic, and that ever correct inference proceeds in accordance with its laws.

Logic is immaturity weaving its nets of gossamer wherewith it aims to catch the behemoth of knowledge. Logic is a crutch for the cripple, but a burden for the swift of foot and a greater burden still for the wise.

Nature cares nothing for logic, our human logic: she has her own, which we do not recognize and do not acknowledge until we are crushed under its wheel

I am like a machine being driven to excessive rotations: the bearings are incandescing and, in a minute, melted metal will begin to drip and everything will turn to nothing. Quick: get cold water, logic. I am pouring it over myself by the bucketload but the logic sizzles on the hot bearings and dissipates elusive white steam into the air.

All the Dachaus must remain standing. The Dachaus, the Belsens, the Buchenwalds, the Auschwitzes - all of them. They must remain standing because they are a monument to a moment in time when some men decided to turn the Earth into a graveyard. Into it they shoveled all of their reason, their logic, their knowledge,,then we become the gravediggers.

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.

Soul-directed events defy logic and ridicule reason.

Logic is the technique by which we add conviction to truth.

People who lean on logic and philosophy and rational exposition end by starving the best part of the mind.

But logic is not all, one needs one's heart to follow an idea.

Mathematicians care no more for logic than logicians for mathematics.

Mathematics expresses values that reflect the cosmos, including orderliness, balance, harmony, logic, and abstract beauty.

Logic can provide you with various facts and figures but can't comprehend them in their totality.

When quite young I can remember I had no thought or wish of surpassing others. I was rather taken with a liking of little arts and bits of learning. My mother carefully fostered a liking for botany, giving me a small microscope and many books, which I yet have. Strange as it may seem, I now believe that botany and the natural system, by exercising discrimination of kinds, is the best of logical exercises. What I may do in logic is perhaps derived from that early attention to botany.

Nothing is as depressing as absolute logic. Look at the maze of French politics perpetrated by a logical people.

I approach my life with logic. I do not act on impulse or emotion. I very seldom find that I say, 'And then I can't think what came over me, but I did this or that or the other.' I nearly always know how I will act and I nearly always act in that way. I don't catch myself out in embarrassing situations because I've acted without forethought. I calculate what I will do.

Sir, we must beware of needless innovation, especially when guided by logic.

We didn't want to live anymore in the old logic. And I like that. The consequence of that is to create the dream of that, but we all know this dream may be not possible. So here we have the key of the ambiguity of the atmosphere of my films. Is it possible, this dream? Is it as funny as it seems, or is it tragic?

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?

President Bush Sr. and Secretary Baker, way back when, told Gorbachev, "We are not going to advance NATO into Eastern Europe. We're not going to - we're not going to advance NATO into East Germany, if you allow the unification of Germany." Where is that pledge? Where is the logic behind a military alliance, devised in the time of communism, before the Berlin Wall fell, now being in the Ukraine, in Poland, in Estonia, in Latvia and Lithuania? I don't understand.

It was the most convulted, ridiculous piece of logic I'd heard in awhile... It was something I would have come up with.

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?

Every song has a composer, every book has an author, every car has a maker, every painting has a painter, and every building has a builder. So it isn't irrational to take this simple logic a little further and say that nature must have had a Maker. It would be irrational to believe that it made itself.

Admit nothing - that was his first rule. Appeal to logic - second rule. Delay the inevitable - third rule.

Right up till the 1980s, SF envisioned giant mainframe computers that ran everything remotely, that ingested huge amounts of information and regurgitated it in startling ways, and that behaved (or were programmed to behave) very much like human beings... Now we have 14-year-olds with more computing power on their desktops than existed in the entire world in 1960. But computers in fiction are still behaving in much the same way as they did in the Sixties. That's because in fiction [artificial intelligence] has to follow the laws of dramatic logic, just like human characters.

As in political revolutions, so in paradigm choice--there is no standard higher than the assent of the relevant community. To discover how scientific revolutions are effected, we shall therefore have to examine not only the impact of nature and of logic, but also the techniques of persuasive argumentation effective within the quite special groups that constitute the community of scientists.

Logic and mathematics are nothing but specialised linguistic structures.

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. This condition is indeed reached by me which is deep, difficult to see, difficult to understand, tranquil, excellent, beyond the reach of mere logic, subtle, and to be realized only by the wise.

Why is it, my shadow-striding friend, that we don't fear dreams? We lose consciousness, lose control, things happen with no apparent logic and abiding by no apparent rules.... We don't fear dreams, but we do fear madness, and death terrifies us.

The plant never lapses into mere arid functionalism; it fashions and shapes according to logic and suitability, and with its primeval force compels everything to attain the highest artistic form.

Not for the first time in my life, and certainly not for the last, a self-righteous gloom had edged out all semblance of logic.

Any useful logic must concern itself with Ideas with a fringe of vagueness and a Truth that is a matter of degree.

Intuitionists think that there are cases in which, say, some identity statement between real numbers is neither true nor false, even though we know that it cannot possibly be false. That is: We know that it cannot not be that a = b, say, but we cannot conclude that a = b. We can't, in general, move from not-not-p to p in intuitionistic logic. , I suggest that the believer in vague objects should say something similar. It can never be true that it is vague whether A is B. But that does not imply that there is always a fact of the matter whether A is B.

Those who desire to rise as high as our human condition allows, must renounce intellectual pride, the omnipotence of clear thinking, belief in the absolute power of logic.

Anything that contradicts experience and logic should be abandoned.
