Quotes About Certainty

... moral certainty is certainty which is sufficient to regulate our behaviour, or which measures up to the certainty we have on matters relating to the conduct of life which we never normally doubt, though we know that it is possible, absolutely speaking, that they may be false.

We absolutely must leave room for doubt or there is no progress and no learning. There is no learning without having to pose a question. And a question requires doubt. People search for certainty. But there is no certainty.

The significant contribution of empiricism was not the eradication of certainty, but the eradication of infallibility as a criterion of certainty. And this shift from infallibilism to fallibilism has profound consequences not only for toleration, but also for the subordination of faith to reason and theology to philosophy.

The very foundation of science is to keep the door open to doubt. Precisely because we keep questioning everything, especially our own premises, we are always ready to improve our knowledge. Therefore a good scientist is never ‘certain’. Lack of certainty is precisely what makes conclusions more reliable than the conclusions of those who are certain: because the good scientist will be ready to shift to a different point of view if better elements of evidence, or novel arguments emerge. Therefore certainty is not only something of no use, but is in fact damaging, if we value reliability.

Another thing very injurious to the child is the tying and cutting of the navel string too soon, which should always be left till the child has not only repeatedly breathed but till all pulsation in the cord ceases. As otherwise the child is much weaker than it ought to be, a part of the blood being left in the placenta which ought to have been in the child and at the same time the placenta does not so naturally collapse, and withdraw itself from the sides of the uterus, and is not therefore removed with so much safety and certainty.

It is...extraordinary intelligence!

The Scripture abounds in commands and cautions for our utmost diligence in our search and inquiry as to whether we are made partakers of Christ or not, or whether His Spirit dwells in us or not-which argue both the difficulty of attaining an assured confidence herein, as also the danger of our being mistaken, and yet the certainty of a good issue upon the diligent and regular use of means to that purpose.

I count it as a certainty that in paradise, everyone naps.

The insistence on complete certainty about the full details of global warming-the most serious threat we have ever faced-is actually an effort to avoid facing the awful, uncomfortable truth: that we must act boldly, decisively, comprehensively, and quickly, even before we know every last detail about the crisis. Those who continue to argue that the appropriate response is merely additional research are simply seeking to camouflage timidity or protect their vested interest in the status quo.

Just as the spectroscope opened up a new astronomy by enabling the astronomer to determine some of the constituents of which distant stars are composed, so the seismograph, recording the unfelt motion of distant earthquakes, enables us to see into the earth and determine its nature with as great a certainty, up to a certain point, as if we could drive a tunnel through it and take samples of the matter passed through.

A great advantage of X-ray analysis as a method of chemical structure analysis is its power to show some totally unexpected and surprising structure with, at the same time, complete certainty.

So we stand there, part of a crowd a thousand people strong, beaming up at the sky with wonder. I knew with a sudden certainty that wherever I am in the future - up in my treehouse, alone in the school cafeteria, or trying to figure out what my teachers are talking about, a part of me will always be right here, right now, wish that giant eye in the sky shining down on me, telling me it's going to be alright.

Moral certainty can deafen people to any truth other than their own.

If I was gay, there’d be no closet. You’d never see the closet I came out of. Why? I would have burned it for kindling by the time I was twelve! Because I know, with all certainty in my mind, there’s nothing wrong with being gay and you know it! And there’s nothing wrong with being into chicks if you’re a girl. And there’s nothing wrong with being into all of it…. How awesome would it be to be bisexual? To just walk into a room and go ‘MMMM, ALRIGHT!!!!’

It is wrong for a man to say that he is certain of the objective truth of any proposition unless he can produce evidence which logically justifies that certainty. This is what Agnosticism asserts; and, in my opinion, it is all that is essential to Agnosticism. That which Agnostics deny and repudiate, as immoral, is the contrary doctrine, that there are propositions which men ought to believe without logically satisfactory evidence; and that reprobation ought to attach to the profession of disbelief in such inadequately supported propositions.

The only certainty is uncertainty

One must treat theory-in-use as both a psychological certainty and an intellectual hypothesis.

Man's quest for knowledge is an expanding series whose limit is infinity, but philosophy seeks to attain that limit at one blow, by a short circuit providing the certainty of complete and inalterable truth. Science meanwhile advances at its gradual pace, often slowing to a crawl, and for periods it even walks in place, but eventually it reaches the various ultimate trenches dug by philosophical thought, and, quite heedless of the fact that it is not supposed to be able to cross those final barriers to the intellect, goes right on.

And it would be a spare life he would be certain to lead as a schoolteacher in some urban location. But he had a serenity that came with the choice of the life he wanted to live. And this serenity and certainty I have seen only among those who have the armour of books close by.

We see it [the as-yet unseen, probable new planet, Neptune] as Columbus saw America from the coast of Spain. Its movements have been felt, trembling along the far-reaching line of our analysis with a certainty hardly inferior to that of ocular demonstration.

The character truest to itself becomes eccentric rather than immovably centered, as Emerson defined the noble character of the hero. At the edge, the certainty of borders gives way. We are more subject to invasions, less able to mobilize defenses, less sure of who we really are, even as we may be perceived by others as a person of character. The dislocation of self from center to indefinite edge merges us more with the world, so that we can feel blest by everything.

A tender young cork, however, would have had no more chance against a pair of corkscrews, or a tender young tooth against a pair of dentists, or a little shuttlecock against two battledores, than I had against Uriah and Mrs. Heep. They did just what they liked with me; and wormed things out of me that I had no desire to tell, with a certainty I blush to think of.

There’s faith that knows itself as faith, Proyas, and there’s faith that confuses itself for knowledge. The first embraces uncertainty, acknowledges the mysteriousness of the God. It begets compassion and tolerance. Who can entirely condemn when they’re not entirely certain they’re in the right? But the second, Proyas, the second embraces certainty and only pays lip service to the God’s mystery. It begets intolerance, hatred, violence.

Why had we come to the moon? The thing presented itself to me as a perplexing problem. What is this spirit in man that urges him for ever to depart from happiness and security, to toil, to place himself in danger, to risk an even a reasonable certainty of death? It dawned upon me that there in the moon as a thing I ought always to have known, that man is not made to go about safe and comfortable and well fed and amused. ... against his interest, against his happiness, he is constantly being driven to do unreasonable things. Some force not himself impels him, and he must go.

We share in the certainty that people labeled with mental illness are first and above all, human beings. Our lives are precious and are of infinite value.

It is my mind, with its store of images, that gives the world color and sound; and that supremely real and rational certainty which I can "experience" is, in its most simple form, an exceedingly complicated structure of mental images. Thus there is, in a certain sense, nothing that is directly experienced except the mind itself. Everything is mediated through the mind, translated, filtered, allegorized, twisted, even falsified by it. We are . . . enveloped in a cloud of changing and endlessly shifting images.

Certainty is the mark of the commonsense life-gracious uncertainty is the mark of the spiritual life.
