People will hold an opinion because they want to keep the company of others who share the opinion, or because they think it is the respectable opinion, or because they have publicly expressed the opinion in the past and would be embarrassed by a “U-turn,” or because the world would suit them better if the opinion were true, or . . . Perhaps it is better to get on with your family and friends, to avoid embarrassment, or to comfort yourself with fantasies than to believe the truth. But those who approach matters in this way should give up any pretensions to intellectual seriousness. They are not genuinely interested in reality.

Perfect logic applied to insufficient information in limited time almost always results in a flawed decision

Perhaps it's the alien equivalent of a discarded tomato can. Does a beetle know why it can enter the can only from one end as it lies across the trail to the beetle's burrow? Does the beetle understand why it is harder to climb to the left or right, inside the can, than it is to follow a straight line? Would the beetle be a fool to assume the human race put the can there to torment it — or an egomaniac to believe the can was manufactured only to mystify it? It would be best for the beetle to study the can in terms of the can's logic, to the limit of the beetle's ability. In that way, at least, the beetle can proceed intelligently. It may even grasp some hint of the can's maker. Any other approach is either folly or madness.

Persistence wears down resistance.

Physical laws are ruled by logic, and are ungovernable: so when the die comes to rest on its edge, it owes neither apology nor account.

Philosophy is easy... who on the fucking world has said that it's easy... it's not about logic... but and aboutnon logic... once enable logic... once and forever non logic is state disable.

Poetry is seeing everything when there is only one thing. It is looking at a rose but seeing the stars, moons, seas, and trees. It is a truth beyond logic, an experience beyond thought. Poetry is the Earth pausing on its axis in order to manifest itself as a rose.

Prejudice is by definition unreasonable and illogical. A reasoned dislike or a logical objection is not a prejudice, although false reasoning and pseudo logic are often found in the service of prejudice. Prejudice is invariably a symptom of a character defect, but tragically it is one that is shared in some degree by us all. Race, national and cultural prejudice is being recognized by thinking men as the great evil which as brought us to the brink of destruction. Prejudice which finds its focus in the accents,manners and styles of others is passed off as comparatively innocuous, but even this brand of prejudice does more to divide men than does any real differences in ideals and aspirations.

Pure analysis puts at our disposal a multitude of procedures whose infallibility it guarantees; it opens to us a thousand different ways on which we can embark in all confidence; we are assured of meeting there no obstacles; but of all these ways, which will lead us most promptly to our goal? Who shall tell us which to choose? We need a faculty which makes us see the end from afar, and intuition is this faculty. It is necessary to the explorer for choosing his route; it is not less so to the one following his trail who wants to know why he chose it.

Quentin was thin and tall, though he habitually hunched his shoulders in a vain attempt to brace himself against whatever blow was coming from the heavens, and which would logically hit the tall people first.

Pure mathematics consists entirely of assertions to the effect that, if such and such a proposition is true of anything, then such and such another proposition is true of that thing. It is essential not to discuss whether the first proposition is really true, and not to mention what the anything is, of which it is supposed to be true. [...] Thus mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true. People who have been puzzled by the beginnings of mathematics will, I hope, find comfort in this definition, and will probably agree that it is accurate.

Questioning a genius with logic limits his imagination.

Reason itself is fallible, and this fallibility must find a place in our logic.

Rage swallowed remorse. Rage drop-kicked self-pity. Rage murdered sorrow. And then, like blood-red wine tucked into the refrigerator, rage chilled to become cold, calculating anger. Anger was a creature that arrived on her doorstep with a suitcase full of strategy and vengeance. It tipped its hat at her and hopped into her brain. It knocked on the Logic Department's door. It found a broken mirror somewhere in the crevices between her hippocampus and her hypothalamus, and it was wondering if somebody had misplaced it. No retaliation? It scoffed. Think again, missy.

Reasonable doubt trumps everything.

Reason. It is no more reliable a tool than instinct, myth or dream. But it has the potential to be far more dangerous...

Recently I am so much in to numbers, equations & scientific facts! I learned how to link logic to reason, and to be honest sometimes I couldn't, simply because logic is not stander defined, it defers from one to another (it is the science of reasoning), that made me think deeply about life, what is the real reason behind all the unbelievable stories in my life, how can I discover the logic behind what is happening behind the scene! Then it hit me, I discovered that everything is supernaturally working in harmony to serve me at the end, no matter how hard it felt ! I was granted hope in different ways, only in the mysterious equations of love that any logic or reasons can be found, Because of the only logic I found I am able to be alive now! Amazing how God love us, yet we are so blind to see it, because we accept blessings as a given right!

Reason like a sphere? What type of reasoning does a wooden sphere do?" "The circular type, I should think. And, by coincidence, it is my favorite type as well. Perhaps that's why I'm so good at the game.

Reason is an outcome of frailty and resentment. When Will fails to cope with the labour of life, or the life of labour, its fragile remnants are set to construct a slighter world of justifications.

Religion, like science, is only noteworthy when it emphasizes a matter of what is true rather than whose belief is greater or lesser or which deity works for whom. Sincere religion and tested science are similar in that their assertions can be argued logically and objectively; otherwise, we get false cults and babble.

Religion equals logic... but the logic of the human mind can't perceptible it

Religion is a subject which, if the believers used the same "reasoning" to address problems at work as they use to defend their beliefs, they'd soon find themselves unemployed. And if they found their child applying that kind of "reasoning" on a homework assignment they'd wonder what the hell was the wrong with their child.

Religion is beyond the realm of logic, but if any priest, pundit or maulvi tries to justify his religion with logic, it sounds absurd and illogical.

Religion and philosophy have different logics, speak different languages. Their logics are mutually exclusive, languages sometimes overlapping. It is hard to find something really common in them. I think I---a man in totally unconditional pursuit of happiness, whatever it is, wherever it lies---am only supposed to consider which of them has more in common with life!

Religion without sense is like a car with no wheels. You can be in it, but it won’t take you anywhere. We must be logical and good-natured if we want it to take us places for the greater good.

Relying only on logic, on what can be factually established, may inform or intimidate, but it will rarely stir anyone into action or change.

Reason will always be logical, Logic not always reasonable, For truth from reason derivable, And logic falsehood multipliable.

Repetition of an argument proves your determination, not truth.

Review the multiplicity of language-games in the following examples, and in others: Giving orders, and obeying them— Describing the appearance of an object, or giving its measurements— Constructing an object from a description (a drawing)— Reporting an event— Speculating about an event— Forming or teasing a hypothesis— Presenting the results of an experiment in tables and diagrams— Making up a story; and reading it— Singing catches— Guessing riddles— Making riddles— Making a joke; telling it— Solving a problem in practical arithmetic— Translating from one language into another— Asking, thanking, cursing, greeting, praying. —It is interesting to compare the multiplicity of the tools in language and of the ways they are used, the multiplicity of kinds of word and sentence, with what logicians have said about the structure of language. (Including the author of the Tractatus Logico-Philosophicus.)

[Rumsfield's] reply included a complex formulation that would become inextricably associated with him: 'There are known knowns. These are things we know that we know. There are known unknowns. That is to say, there are things that we know we don't know. But there are also unknown unknowns. There are things we don't know we don't know.

Roughly speaking: to say of two things that they are identical is nonsense, and to say of one thing that it is identical with itself is to say nothing.

Sabism is thematic pallet, philosophical colourism, chromatic signature and dual art, bi-chromatic scale, soft scale, poetics of attractiveness, mythologism, actual value, logism of color, active color, logical panel.

Richness and fat does need, In logic clever fine deeds, But paunches never do breed, Fine thoughts or sublime seeds. [45] - 2

Ruthlessness is the most practical of emotions, Reen's voice whispered. She ignored it.

Russell is reputed at a dinner party once to have said, ‘Oh, it is useless talking about inconsistent things, from an inconsistent proposition you can prove anything you like.’ Well, it is very easy to show this by mathematical means. But, as usual, Russell was much cleverer than this. Somebody at the dinner table said, 'Oh, come on!’ He said, 'Well, name an inconsistent proposition,’ and the man said, 'Well, what shall we say, 2 = 1.’ 'All right,’ said Russell, 'what do you want me to prove?’ The man said, 'I want you to prove that you’re the pope.’ 'Why,’ said Russell, 'the pope and I are two, but two equals one, therefore the pope and I are one.

Sapiens don’t behave according to a cold mathematical logic, but rather according to a warm social logic. We are ruled by emotions.

Sadly, because of our tribal brains, science carries a hefty cost. Treasured ideas that are loved by the community may be left behind, unable to compete with conflicting observations. Admired heroes may be found to have been mistaken. Years of hard work can amount to nothing thanks to a single observation, making a lifetime of effort seem like a waste of time. For our tribal brain, the philosopher’s toolbox is full of double-edged knives, capable of cutting away our hopes with the myths.

Scientific literacy is a rather noble ideal. Achieving it, however, is problematic thanks to our tribal brains. If science is equated with knowledge, then communicating facts, figures, and theories should be a way to increase the public’s level of engagement with it. However, this boils down to the authority distributing the information. Who do you listen to when there are conflicting sources? Our brain’s desire for certainty and its tendency to evaluate new information based on social clues means anybody painted as an expert, who sounds confident, shares our values and flatters our expectations, is more likely to win over our opinion...regardless of the scientific merits of their argument.

She plays chess from the passions and I play it from logic and she usually wins. Once, I took her queen and she hit me.” Though, he recalled, not sufficiently brutally to require that he tie her wrists together with his belt, force her to kneel and beat her until she toppled over sideways. She raised a strangely joyous face to him; the pallor of her skin and the almost miraculous lustre of her eyes startled and even awed him.

Selon Gilles Deleuze et Félix Guattari: [...] "C'est une véritable haine qui anime la logique, dans sa rivalité ou sa volonté de supplanter la philosophie. Elle tue le concept deux fois. Pourtant le concept renaît, parce qu'il n'est pas une fonction spécifique, et parce qu'il n'est pas une proposition logique : il n'appartient à aucun système discursif, il n'a pas de référence. Le concept se montre, et ne fait que se montrer. Les concepts sont des monstres qui renaissent de leurs débris." Il serait malaisé pour moi d'expliquer ce que ce passage veut dire [...]. Renaître de ses débris, pour un monstre, est une opération dont personne ne sait grand-chose. Ne pourrait-on pas aussi bien affirmer, avec autant de raisons, qu'un concept est une machine à laver ou un chameau ?

She had been too well-trained to allow her emotions to take control of her at the time, but the feelings were too strong to quietly recede into a regimen of critical thought. Deep inside her they stewed, logic and reason slowly boiling off. Reduced to their essence, her feelings became more potent, condensed into an emotional certainty. I should have saved them.

Shepherd Book: What are we up to, sweetheart? River: Fixing your Bible. Book: I, um... What? River: Bible's broken. Contradictions, false logistics - doesn't make sense. Shepherd Book: No, no. You-you-you can't... River: So we'll integrate non-progressional evolution theory with God's creation of Eden. Eleven inherent metaphoric parallels already there. Eleven. Important number. Prime number. One goes into the house of eleven eleven times, but always comes out one. Noah's ark is a problem. Shepherd Book: Really? River: We'll have to call it early quantum state phenomenon. Only way to fit 5000 species of mammal on the same boat. Shepherd Book: River, you don't fix the Bible. River: It's broken. It doesn't make sense. Book: It's not about making sense. It's about believing in something, and letting that belief be real enough to change your life. It's about faith. You don't fix faith, River. It fixes you.

She's not quite making sense, but no one does all the time.

Smartass Disciple: Which one was first created, time or things? Master of Stupidity: No things, no changes. No changes, no time.

So each one of you agrees to disagree with whatever the other one agrees with, but if you both disagree with the same thing, aren't you really in agreement?

Some persons fancy that bias and counter-bias are favorable to the extraction of truth–that hot and partisan debate is the way to investigate. This is the theory of our atrocious legal procedure. But Logic puts its heel upon this suggestion. It irrefragably demonstrates that knowledge can only be furthered by the real desire for it, and that the methods of obstinacy, of authority and every mode of trying to reach a foregone conclusion, are absolutely of no value. These things are proved. The reader is at liberty to think so or not as long as the proof is not set forth, or as long as he refrains from examining it. Just so, he can preserve, if he likes, his freedom of opinion in regard to the propositions of geometry; only, in that case, if he takes a fancy to read Euclid, he will do well to skip whatever he finds with A, B, C, etc., for, if he reads attentively that disagreeable matter, the freedom of his opinion about geometry may unhappily be lost forever.

Someone. Everyone. Anyone. No-one. One. One can't be everyone, but there isn't more than one everyone, at the same time. And at the same time no-one can't be someone, but anyone can be one, and also anyone can be a no-one. To sum up - everyone is someone, and any-one becomes a no-one if you divide the one part long enough by every part of every-one, so in conclusion, I have no idea what I’m talking about, basically.

Sometimes I think humans have a common sense that completely defies logic.

Sometimes the endpoint is the startpoint

sometimes the most logical thought that come out from our head is far from "logic" in reality.
