Quotes About Certainty

Climate Change is a national security issue. We found that climate instability will lead to instability in geopolitics and impact American military operations around the world.

If you wait until you have 100 percent certainty, something bad is going to happen on the battlefield.

While the dogmatist is harmful, the sceptic is useless ...; one is certain of knowing, the other of not knowing. What philosophy should dissipate is certainty, whether of knowledge or of ignorance. Knowledge is not so precise a concept as is commonly thought. Instead of saying 'I know this', we ought to say 'I more or less know something more or less like this'. ...

Out of the element of participation follows the certainty of faith; out of the element of separation follows the doubt in faith. And each is essential for the nature of faith.

Otherwise it would be indifference.

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.

It is...extraordinary intelligence!

She loved Bram in a clear-eyed way she’d never loved her ex-husband, no rose-colored glasses or mindless giddiness, no Cinderella fantasies or false certainty that he’d put her life in order. What she felt for Bram was messy, honest, and soul-deep. He felt like…part of her, the best and the worst. Like someone she wanted to struggle through life with; share triumphs and catastrophes; share holidays, birthdays, every days

One third, more or less, of all the sorrow that the person I think I am must endure is unavoidable. It is the sorrow inherent in the human condition, the price we must pay for being sentient and self-conscious organisms, aspirants to liberation, but subject to the laws of nature and under orders to keep on marching, through irreversible time, through a world wholly indifferent to our well-being, toward decrepitude and the certainty of death. The remaining two thirds of all sorrow is homemade and, so far as the universe is concerned, unnecessary.

I then began to study arithmetical questions without any great apparent result, and without suspecting that they could have the least connexion with my previous researches. Disgusted at my want of success, I went away to spend a few days at the seaside, and thought of entirely different things. One day, as I was walking on the cliff, the idea came to me, again with the same characteristics of conciseness, suddenness, and immediate certainty, that arithmetical transformations of indefinite ternary quadratic forms are identical with those of non-Euclidian geometry.

This is what it is to be human: to see the essential existential futility of all action, all striving -- and to act, to strive. This is what it is to be human: to reach forever beyond your grasp. This is what it is to be human: to live forever or die trying. This is what it is to be human: to perpetually ask the unanswerable questions, in the hope that the asking of them will somehow hasten the day when they will be answered. This is what it is to be human: to strive in the face of the certainty of failure. This is what it is to be human: to persist.

"What is the meaning of life?" This question has no answer except in the history of how it came to be asked. There is no answer because words have meaning, not life or persons or the universe itself.

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.

In the end it all comes down to this: you have a choice (or more accurately a rolling tangle of choices) between giving your work your best shot and risking that it will not make you happy, or not giving it your best shot - and thereby guaranteeing that it will not make you happy. It becomes a choice between certainty and uncertainty. And curiously, uncertainty is the comforting choice.

He detached himself from himself (s'est détacher de lui-même", Fr.), has identified himself with something greater and more lasting than himself; his homeland ("patrie", Fr.); thus, while dying as an individual, he has the certainty to survive in a larger existence.
