Quotes About Certainty

Scientists do not believe in fundamental and absolute certainties. For the scientist, certainty is never an end, but a search; not the ordering of certainty, but its exploration. For the scientist, certainty represents the highest degree of probability.

Every patient reacts a little differently, both biologically and psychologically. The only constant in cancer is inconstancy; the only certainty is a future of uncertainty, a truism for all of modern life but one made vivid by life-threatening illness.

God himself was once as we are now, and is an exalted man, and sits enthroned in yonder heavens! That is the great secret.... It is the first principle of the Gospel to know for a certainty the Character of God, and to know... that he was once a man like us.... Here, then, is eternal life - to know the only wise and true God; and you have got to learn how to be Gods yourselves... the same as all Gods have done before you.

No one can forecast the economy with certainty.

He wondered how he could ever have thought of the planets, even of the Earth, as islands of life and reality floating in a deadly void. Now with a certainty which never after deserted him, he saw the planets - as mere holes or gaps in the living heaven - excluded and rejected wastes of heavy matter and murky air, formed not by addition to, but by subtraction from, the surrounding brightness.

The good gardener knows with absolute certainty that if he does his part, if he gives the labour, the love, and every aid that his knowledge of his craft, experience of the conditions of his place, and exercise of his personal wit can work together to suggest, that so surely will God give the increase. Then with the honestly-earned success comes the consciousness of encouragement to renewed effort, and, as it were, an echo of the gracious words, 'Well done my good and faithful servant'.

The afflicted are not listened to. They are like someone whose tongue has been cut out and who occasionally forgets the fact. When they move their lips no ear perceives any sound. And they themselves soon sink into impotence in the use of language, because of the certainty of not being heard.

Summers was simply a master explainer, able to deftly boil down the complexities of economic and financial, and to put them in terms the non-expert could understand.

As its best, SF is the medium in which our miserable certainty that tomorrow will be different from today in ways we cant predict, can be transmuted to a sense of excitement and anticipation, occasionally evolving into awe.

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.

Grace cannot prevail...until our lifelong certainty that someone is keeping score has run out of steam and collapsed.

When you believe you have found an important scientific fact, and are feverishly curious to publish it, constrain yourself for days, weeks, years sometimes, fight yourself, try and ruin your own experiments, and only proclaim your discovery after having exhausted all contrary hypotheses.

A beautiful woman, Simone Weil said, seeing herself in the mirror, knows "This is I." An ugly woman knows with equal certainty, "This is not I." Maud knew this neat division represented an over-simplification. The doll-mask she saw had nothing to do with her, nothing.

There are many paths to enlightenment. Some of us who have expanded to a degree of illumination have thereafter preached the dogmatic certainty of one particular path. But enlightenment doesn't care how you get there. And if you aren't going to be thinking about it in paradise, then don't worry about it now.

But no one can predict of a certainty what will happen. And none of it will change how I intend to spend the rest of my life. I will live it on my terms. And you... you can have all of me or nothing. I won't be an invalid any longer. Not even if it means losing you.

Be sure of the foundation of your life. Know why you live as you do. Be ready to give a reason for it. Do not, in such a matter as life, build an opinion or custom on what you guess is true. Make it a matter of certainty and science.

The term ignorant is indeed perhaps an overstatement, implying as it does that something is known somewhere, whereas in reality we are not even sure of this: we in fact cannot aver with any degree of certainty that we are ignorant. Yet this is not so bad; we have at any rate kept our open-mindedness -- that, at least, we may be sure that we have -- and are not in any danger, or so it seems, of freezing into the pious attitudes of those true spiritual bigots whose faces are turned toward eternity and who therefore can see nothing.

Once you have given up the ghost, everything follows with dead certainty, even in the midst of chaos.

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.

Scripture will ultimately suffice for a saving knowledge of God only when its certainty is founded upon the inward persuasion of the Holy Spirit. Indeed, these human testimonies which exist to confirm it will not be vain if, as secondary aids to our feebleness, they follow that chief and highest testimony. But those who wish to prove to unbelievers that Scripture is the Word of God are acting foolishly, for only by faith can this be known.

Almost all religions provide opportunities for human beings to convince themselves of their own righteousness, to speak in the name of God, and even to go to war on God's behalf. This 'blasphemy of certainty' is also rife among secularists who in their case have not God but science or the proletariat on their side.

Revolution is the only thing, the only power, that ever worked out freedom for any people. The powers that have ruled long and learned to love ruling, will never give up that prerogative until they must, till they see the certainty of overthrow and destruction if they do not. To plant-to revolutionize-these are the twin stars that have ruled our pathway. What have we then to dread in the word Revolution-we, the children of rebels!

The court was unable to rule on all circumstances in which nuclear weapons might be used, and it said in view of the problems, the risks posed by nuclear weapons, and in view of the lack of certainty of the law in all circumstances, the best course is fulfilling the obligation of good faith negotiations of nuclear disarmament contained in the nuclear non-proliferation treaty.

This surpassed the fear of death. Death would be a mercy if it would make the feeling stop, the uncontrollable panic mingling with the mind-scrambling certainty of something sinister approaching, something with no need to hurry, something that would not be so kind as to let him die. The fear was palpable, suffocating, irresistible.

I never wavered in my certainty that God did not exist. I was simply liberated by the thought that there might be a way to engage with religion without having to subscribe to its supernatural content - a way, to put it in more abstract terms, to think about Fathers without upsetting my respectful memory of my own father. I recognized that my continuing resistance to theories of an afterlife or of heavenly residents was no justification for giving up on the music, buildings, prayers, rituals, feasts, shrines, pilgrimages, communal meals and illustrated manuscripts of the faiths.
