İt is not true that the more you read, the more intelligent you become. Without thinking you cannot be intelligent. You need to think in order to avoid ready-form answers, which can satisfy the inquisitive mind, but cannot give a clear insight into anything, making the brain only some kind of container of various information similar to the microchip of robot or computer. You would become a social robot whose brain contains various information but cannot think. That is why most men know a lot, but learn nothing from that knowledge. Most men know a lot, but can understand nothing on the base of that knowledge. However, it is not also true that the more you think, the more intelligent you become. Without reading you cannot be intelligent. You need to read, especially scientific literature, in order to model any problem which fascinates your mind in a proper and clear way. There cannot be vacuum in the human mind, if there is no scientific rationality there, then mystical irrationality would cover the whole space in your mind. There is no need to emphasize that being under the strong influence of mystical irrationality would confuse your mind more and more. But if scientific rationality appears, mystical irrationality disappears immediately.

It is one of the greatest Curses visited upon Mankind, he told me, that they shall fear where no Fear is: this astrological and superstitious Humour disarms men's Hearts, it breaks their Courage, it makes them help to bring such Calamities on themselves. Then he stopped short and looked at me, but my Measure was not yet fill'd up so I begg' d him to go on, go on. And he continued: First, they fancy that such ill Accidents must come to pass, and so they render themselves fit Subjects to be wrought upon; it is a Disgrace to the Reason and Honour of Mankind that every fantasticall Humourist can presume to interpret the Skies (here he grew Hot and put down his Dish) and to expound the Time and Seasons and Fates of Empires, assigning the Causes of Plagues and Fires to the Sins of Men or the Judgements of God. This weakens the Constancy of Humane Actions, and affects Men with Fears, Doubts, Irresolutions and Terrours. I was afraid of your Moving Picture, I said without thought, and that was why I left. It was only Clock-work, Nick. But what of the vast Machine of the World, in which Men move by Rote but in which nothing is free from Danger? Nature yields to the Froward and the Bold. It does not yield, it devours: You cannot master or manage Nature. But, Nick, our Age can at least take up the Rubbidge and lay the Foundacions: that is why we must study the principles of Nature, for they are our best Draught. No, sir, you must study the Humours and Natures of Men: they are corrupt, and therefore your best Guides to understand Corrupcion. The things of the Earth must be understood by the sentient Faculties, not by the Understanding. There was a Silence between us now until Sir Chris. says, Is your Boy in the Kitchin? I am mighty Hungry.

It may be considered as an honour to the animal faculties of man to obtain redress by courage and danger, but it is far greater honour to the rational faculties to accomplish the same object by reason, accommodation, and general consent.

It's difficult to know where to begin, sir.' 'Yes, the beginning is the tricky part. But perhaps there is no beginning, perhaps we can't look that far back.' He got up from his desk and went over to the window, from where he could see thin pillar of smoke rising into the clouds. 'I never know where anything comes from, Walter.' 'Comes from, sir?' 'Where you come from, where I come from, where all this comes from.' And he gestured at the offices and homes beneath him. He was about to say something else but he stopped, embarrassed; and in any case he was coming to the limits of his understanding. He was not sure if all the movements and changes in the world were part of some coherent development, like the weaving of a quilt which remains one fabric despite its variegated pattern. Or was it a more delicate operation than this - like the enlarging surface of a balloon in the sense that, although each part increased at the same rate of growth as every other part, the entire object grew more fragile as it expanded? And if one element was suddenly to vanish, would the others disappear also - imploding upon each other helplessly as if time itself were unravelling amid a confusion of Sights, calls, shrieks and phrases of music which grew smaller and smaller? He thought of a train disappearing into the distance, until eventually only the smoke and the smell of its engine remained.

It's hard to imagine a more extraordinary claim than that some hidden intelligence created a universe of more than a hundred billion galaxies, each containing more than a hundred billion stars, and then waited more than 13.7 billion years until a planet in a remote corner of a single galaxy evolved an atmosphere sufficiently oxygenated to support life, only to then reveal his existence to an assortment of violent tribal groups before disappearing again.

It takes a huge amount of culture to normalize "crazy", and of course that's its main focus

It takes irrationality to hold, but intelligence to profit from, conflicting beliefs and attitudes.

It takes courage to speak or react way slower than you think.

It was a fairy tale, no fooling. It was unreality becoming real. This frightened her. Because people don't care for unreality becoming real. It pricks their well-fed minds, you see, with something like a hunger pang. They prefer the logical stuffiness of expectancy. It is only at certain times that they weaken, letting imagination in. That's the time to get them. (“The Disinheritors”)

It was a good answer that was made by one who when they showed him hanging in a temple a picture of those who had paid their vows as having escaped shipwreck, and would have him say whether he did not now acknowledge the power of the gods, — ‘Aye,’ asked he again, ‘but where are they painted that were drowned after their vows?’ And such is the way of all superstition, whether in astrology, dreams, omens, divine judgments, or the like; wherein men, having a delight in such vanities, mark the events where they are fulfilled, but where they fail, though this happens much oftener, neglect and pass them by.

It was definitely not something that could be understood within any acceptable context. But then, wasn’t it the case that all people believed they were rational? What they were doing in their minds and what they were doing with their hands were never the same thing.

I've seen people severely messed up by their own knowledge of biases. They have more ammunition with which to argue against anything they don't like. And that problem—too much ready ammunition—is one of the primary ways that people with high mental agility end up stupid, in Stanovich's "dysrationalia" sense of stupidity.

I’ve suppressed my aspirations to forget all rationality and let the moment explain everything, for nothing to be said and everything understood. If only I knew how to let these feelings out.

I want to say a word to the Brahmins: In the name of God, religion, sastras you have duped us. We were the ruling people. Stop this life of cheating us from this year. Give room for rationalism and humanism.

Logic, if used as the main instrument for thinking, frustrates the functions of the mind – it doesn‘t improve them. Great ideas are often the result of creativity, serendipity and higher pleasures. A logical thought experiment may be thus successful only if it is infused with the aforementioned three elements.

Logiškai mąstė, o paskui elgėsi logiška išvada. Tačiau daugelis iš mūsų, įtariu, daro priešingai: priima instinktyvų sprendimą, paskui kuria priežasčių infrastruktūrą jam pateisinti. O rezultatą pavadina sveiku protu.

Logic stays true, wherever you may go, So logic never tells you where you live.

Love is a country where you leave the passports of rationality at the customs when you enter, to be collected when you exit.

I try to be rational (or at least my imaginary facsimile of what rationality is supposed to be). I try to look at the available data objectively (fully aware that this is impossible). I try to extrapolate what may be happening now into what will be happening later. And this, of course, is where naïve realism punches me in the throat. There's simply no way around the limited ceiling of my own mind. It's flat-out impossible to speculate on the future without (a) consciously focusing on the most obvious aspects of what we already know and (b) unconsciously excluding all the things we don't have the intellectual potential to grasp.

It seems that life, in order to maintain itself, must revolt every so often against man's ceaseless attempts to master its irrational forces with his mind.

Man: an irrational being who imagines himself to be a rational one.

Many of the cataclysmic leadership failures were failures of rationality. The pendulum of leadership development needs to swing back toward the rational: strategy, creativity, foresight, decision-making, and analytics.

Melancholy is an escape not from reality, but unreality of the world.

Mind you, I cannot swear that my story is true. It may have been a dream; or worse, a symptom of some severe mental disorder. But I believe it is true. After all, how are we to know what things there are on earth? Strange monstrosities still exist, and foul, incredible perversions. Every war, each new geographical or scientific discovery, brings to light some new bit of ghastly evidence that the world is not altogether the same place we fondly imagine it to be. Sometimes peculiar incidents occur which hint of utter madness. How can we be sure that our smug conceptions of reality actually exist? To one man in a million dreadful knowledge is revealed, and the rest of us remain mercifully ignorant. There have been travelers who never came back, and research workers who disappeared. Some of those who did return were deemed mad because of what they told, and others sensibly concealed the wisdom that had so horribly been revealed. Blind as we are, we know a little of what lurks beneath our normal life. There have been tales of sea serpents and creatures of the deep; legends of dwarfs and giants; records of queer medical horrors and unnatural births. Stunted nightmares of men's personalities have blossomed into being under the awful stimulus of war, or pestilence, or famine. There have been cannibals, necrophiles, and ghouls; loathsome rites of worship and sacrifice; maniacal murders, and blasphemous crimes. When I think, then, of what I saw and heard, and compare it with certain other grotesque and unbelievable authenticities, I begin to fear for my reason.

Most reject the more repugnant or indefensible dogmas while still holding onto some core belief. Many believers will proudly describe themselves as "reasonable" or "rational" based on how little of their religion they still embrace versus how much they now reject. I think it's funny when people realize that the less you believe the more reasonable you are, but they stop before they reach the logical conclusion.

Nations that take pride in or glorify war, violence and death are sick societies. When unbridled patriotism trumps humanity, peace, justice & rationality, it becomes a poisonous cancer that is both abhorrent as well as mortiferous.

Never trust books on the question of whether or not to trust your rational thinking. Trust your rational thinking on the question of whether or not to trust the books.

No being with a sexual appetite can be a rational being.

No validation of our rationality - of our very sanity - can be accomplished using our rationality itself. How can a person operating within a system of beliefs, including beliefs about beliefs, get outside that system to determine whether it is rational? If your entire system becomes infected with madness, including the very rules by which you reason, then how can you ever reason your way out of your madness?

Obviously, al-Ghazali rejected the Mu‘tazilite position that there is no faith without reason, or that faith requires rational assent, since for him reason is “blind.

Of course, I rationalize the fear. I realize it’s not real, that my house isn’t burning down, that the deer aren’t going to kill me.

Of course, when you shut off your brain from rational analysis, any book is dangerous. Taking literally ancient parables from thousands of years ago is much more dangerous than playing with a loaded gun. Ancient scrawls, written by different authors in different centuries with different agendas--yeah, let's get mad literal about that. The literalness problem is compounded in religion by the circular logic of not being allowed to question anything, or else you're lacking faith.

Oh, you humans may prefer empathy and mercy, but that's like intuiting the answer to an equation: you still have to go back and work the problem to be certain you were right. We can come to genuinely moral conclusions by our own paths.

Once upon a time, there was a man who was convinced that he possessed a Great Idea. Indeed, as the man thought upon the Great Idea more and more, he realized that it was not just a great idea, but the most wonderful idea ever. The Great Idea would unravel the mysteries of the universe, supersede the authority of the corrupt and error-ridden Establishment, confer nigh-magical powers upon its wielders, feed the hungry, heal the sick, make the whole world a better place, etc. etc. etc. The man was Francis Bacon, his Great Idea was the scientific method, and he was the only crackpot in all history to claim that level of benefit to humanity and turn out to be completely right.

Once your fairytale gets shattered multiple times, life will finally paint reality in its place.

One could be forgiven for supposing that rationality (or, more softly, ‘reasonableness’) is irrelevant – and even possibly opposed – to being a good lover. This is perhaps because we tend to think of love as a feeling, rather than as an achievement of intelligence. A reasonable or rational person is not one who is only interested in logic, or someone who tries in a cold, robotic fashion to substitute calculation and analysis for kindness or yearning. We are reasonable when we are moved by accurate explanation. Thus a reasonable person is slow to anger; they do not jump to conclusions

One of my colleagues in Duke, Ralph Keeney, noted that America's top killer isn't cancer or heart disease, nor is it smoking or obesity. It's our inability to make smart choices and overcome our own self-destructive behaviours. Ralph estimates that about half of us will make a lifestyle decision that will ultimately lead us to an early grave. And as if this were not bad enough, it seems that the rate at which we make these deadly decisions is increasing at an alarming pace. I suspect that over the next few decades, real improvements in life expectancy and quality are less likely to be driven by medical technology than by improved decision making. Since focusing on long-term benefits is not our natural tendency, we need to more carefully examine the cases in which we repeatedly fail, and try to come up with some remedies for these situations. For an overweight movie loved, the key might be to enjoy watching a film while walking on the treadmill. The trick is to find the right behavioural antidote for each problem. By pairing something that we love with something that we dislike but that is good for us, we might be able to harness desire with outcome - and thus overcome some of the problems with self-control we face every day.

Love of Truth is one of the strongest motives for replacing what really happens by a streamlined account or, to express it in a less polite manner -- love of truth is one of the strongest motives for deceiving oneself and others.

One obvious palliative of the evils of democracy in its present form would be to encourage much more publicity and initiative on the part of civil servants. They ought to have the right, and, on occasion, the duty, to frame Bills in their own names, and set forth publicly the arguments in their favor.

One of chief pieces of advice I give to aspiring rationalists is "Don't try to be clever." And, "Listen to those quiet, nagging doubts." If you don't know, you don't know what you don't know, you don't know how much you don't know, and you don't know how much you needed to know.

One's very own free, unfettered desire, one's own whim, no matter how wild, one's own fantasy, even though sometimes roused to the point of madness -- all this constitutes precisely that previously omitted, most advantageous advantage which isn't included under any classification and because of which all systems and theories are constantly smashed to smithereens.

Only a measured rationing of our egos can lead us down a path of measured rationality.

Only education, self-respect and rational qualities will uplift the down-trodden.

On your quest to spirituality it is often required to suspend your rationality; but true spirituality asks that you enhance your rationality.

Our propensity to overvalue what we own is a basic human bias, and it reflects a more general tendency to fall in love with, and be overly optimistic about, anything that has to do with ourselves. Think about it - don't you feel that you are a better-than-average driver, are more likely to be able to afford retirement, and are less likely to suffer from high cholesterol, get a divorce, or get a parking ticket if you overstay your meter by a few minutes? This positivity bias, as psychologists call it, has another name: "The Lake Wobegone Effect", named after the fictional town in Garrison Keillor's popular radio series 'A Prairie Home Companion', In Lake Wobegone, according to Keillor, "all the women are strong, all the men are good-looking, and all the children are above average." I don't think we can become more accurate and objective in the way we think about our children and houses, but maybe we can realize that we have such biases and listen more carefully to the advice and feedback we get from the others.

Out of a single man, they get a thousand: homo economicus, homo politicus, homo physico-chimicus, homo endocrinus, homo skeletonicus, homo emotions, homo percipiens, homo libidinosus, homo peregrinans, homo ridens, homo ratiocinans, homo artifex, homo aestbeticus, homo religiosus, homo sapiens, homo historicus, homo ethnographicus, and many, many more. But at the very end of the production line in this laboratory of mine sits a Scienter who is quite unique. Three thousand brains in one. His function is to collect all the data and clarifications written up by the specialist Scienters. When he has collated everything, he is convinced that he has clasped the red rabbit or the essential man entire to his understanding. There you are, you can see him from here,' he ended, with a sign to one of his assistants who brought me a pair of binoculars. I put them to my eyes and, indeed, at the far end of the gallery, I saw the Omniscienter. There he was, an enormous cranial dome with a tiny, shapeless, crumpled face, which seemed to me to be hanging by the ears from the two ebony knobs on the back of a raised throne. Swinging to and fro beneath this head was a little cloth puppet which dangled its empty trouser legs over the crimson plush seat. His tiny right arm was kept aloft by means of a wire, and the index finger rested on his temple in the gesture of one who knows. Above the throne ran a banner bearing this inscription: I KNOW EVERYTHING, BUT I DON'T UNDERSTAND ANY OF IT

P.C. Hodgell said - That which can be destroyed by the truth should be. Do not flinch from experiences that might destroy your beliefs. The thought you cannot think controls you more than thoughts you speak aloud. Submit yourself to ordeals and test yourself in fire. Relinquish the emotion which rests upon a mistaken belief, and seek to feel fully that emotion which fits the facts. If the iron approaches your face, and you believe it is hot, and it is cool, the Way opposes your fear. If the iron approaches your face, and you believe it is cool, and it is hot, the Way opposes your calm. Evaluate your beliefs first and then arrive at your emotions. Let yourself say - If the iron is hot, I desire to believe it is hot, and if it is cool, I desire to believe it is cool.

People go funny in the head when talking about politics. The evolutionary reasons for this are so obvious as to be worth belaboring: In the ancestral environment, politics was a matter of life and death. And sex, and wealth, and allies, and reputation... When, today, you get into an argument about whether "we" ought to raise the minimum wage, you're executing adaptations for an ancestral environment where being on the wrong side of the argument could get you killed. Being on the right side of the argument could let you kill your hated rival! [...] Politics is an extension of war by other means. Arguments are soldiers. Once you know which side you're on, you must support all arguments of that side, and attack all arguments that appear to favor the enemy side; otherwise it's like stabbing your soldiers in the back—providing aid and comfort to the enemy. People who would be level-headed about evenhandedly weighing all sides of an issue in their professional life as scientists, can suddenly turn into slogan-chanting zombies when there's a Blue or Green position on an issue.

People who are more rational don't perceive emotion less, they just regulate it better.

Perfect rationality consists, not in believing what is true, but in attaching to every proposition a degree of belief corresponding to its degree of credibility.
