Doubt is the feeling of uncertainty about something, calling into question whether something is true or possible. Uncertainty is a feeling or status where something is not known, and can also signal a lack of conviction. Doubt and uncertainty usually carry a connotation of less intensity than skepticism.
It would be better for us to have some doubts in an honest pursuit of truth, than it would be for us to be certain about something that was not true.
When men are most sure and arrogant they are commonly most mistaken, giving views to passion without that proper deliberation which alone can secure them from the grossest absurdities.
Everything worth doing in the world is a desperate gamble, a game of chance, where nothing is certain.
What is love? Is it not a wild and sublime speculation that can end in ecstasy or despair?
What is courage? Is it not a hazardous risk of fortune that can end in victory or defeat?
What is adventure? Is it not a blind leap in the dark that can end in joy or disaster?
As we know, there are known knowns. There are things we know we know. We also know there are known unknowns. That is to say we know there are some things we do not know. But there are also unknown unknowns, the ones we don’t know we don’t know.
The great lesson here for all imaginatively gridlocked systems is that the acceptance and even cherishing of uncertainty is critical to keeping the human mind from voyaging into the delusion of omniscience.
Creativity requires the courage to let go of certainties.
Philosophy when superficially studied, excites doubt, when thoroughly explored, it dispels it.
Lord, make me an instrument of your peace; where there is hatred, let me sow love; where there is injury, pardon; where there is doubt, faith; where there is despair, hope; where there is darkness, light; and where there is sadness, joy
You may be deceived if you trust too much, but you will live in torment if you don’t trust enough.
The beginning of knowledge is the discovery of something we do not understand.
The only limit to our realization of tomorrow will be our doubts of today.
What replaces fear? A capacity to trust the abundance of life. All wisdom traditions posit the profound truth that there are two fundamental ways to live life: from fear and scarcity or from trust and abundance…. We come to believe that even if something unexpected happens or if we make mistakes, things will turn out all right, and when they don’t, life will have given us an opportunity to learn and grow.
Madness is the result not of uncertainty but of certainty.
We are on the road to producing a race of men too mentally modest to believe in the multiplication table. We are in danger of seeing philosophers who doubt the law of gravity as being a mere fancy of their own. Scoffers of old time were too proud to be convinced; but these are too humble to be convinced.
It is not bigotry to be certain we are right; but it is bigotry to be unable to imagine how we might possibly have gone wrong.
One’s first step in wisdom is to question everything – and one’s last is to come to terms with everything.
If I am fool, it is, at least, a doubting one; and I envy no one the certainty of his self-approved wisdom.
It’s being here now that’s important. There’s no past and there’s no future. Time is a very misleading thing. All there is ever, is the now. We can gain experience from the past, but we can’t relive it; and we can hope for the future, but we don’t know if there is one.
There is a kind of courtesy in skepticism. It would be an offense against polite conventions to press our doubts too far.
Profound skepticism is favorable to conventions, because it doubts that the criticism of conventions is any truer than they are.
The future has a way of arriving unannounced.
Life is about not knowing, having to change, taking the moment and making the best of it without knowing what’s going to happen next. Delicious ambiguity.
Moral certainty is always a sign of cultural inferiority. The more uncivilized the man, the surer he is that he knows precisely what is right and what is wrong. All human progress, even in morals, has been the work of men who have doubted the current moral values, not of men who have whooped them up and tried to enforce them. The truly civilized man is always skeptical and tolerant, in this field as in all others. His culture is based on “I am not too sure.”
A man must not swallow more beliefs than he can digest.
An absolute can only be given in an intuition, while all the rest has to do with analysis.
Doubt everything or believe everything: these are two equally convenient strategies. With either we dispense with the need for reflection.
Man’s greatest asset is the unsettled mind.
Doubt is part of all religion. All the religious thinkers were doubters.
I’ve put in so many enigmas and puzzles that it will keep the professors busy for centuries arguing over what I meant, and that’s the only way of insuring one’s immortality.
Our doubts are traitors and make us lose the good we often might win, by fearing to attempt.
