As soon as one returns to Doubt (if it could be said that one has ever left it), undertaking anything at all seems not so much useless as extravagant. Doubt works deep within you like a disease, or even more effectively, like a faith.
Emil Cioran
Most of all, faith brings recognition that our quest never leads us to certainty. We are always uncertain, always in doubt that our way is God's way. That self-doubt makes it possible to be reconciled to one another. It is faith that makes the reconciling work of politics possible.
John Danforth
But how is the spirit of expenditure to be exorcised? Not by preaching; I doubt if even by yours. I seriously doubt whether it will ever give place to the old spirit of economy, as long as we have the income-tax. There, or hard by, lie questions of deep practical moment.
William Ewart Gladstone
The scientist has a lot of experience with ignorance and doubt and uncertainty, and this experience is of very great importance, I think. When a scientist doesn’t know the answer to a problem, he is ignorant. When he has a hunch as to what the result is, he is uncertain. And when he is pretty damn sure of what the result is going to be, he is still in some doubt. We have found it of paramount importance that in order to progress, we must recognize our ignorance and leave room for doubt. Scientific knowledge is a body of statements of varying degrees of certainty — some most unsure, some nearly sure, but none absolutely certain. Now, we scientists are used to this, and we take it for granted that it is perfectly consistent to be unsure, that it is possible to live and not know. But I don’t know whether everyone realizes this is true. Our freedom to doubt was born out of a struggle against authority in the early days of science. It was a very deep and strong struggle: permit us to question — to doubt — to not be sure. I think that it is important that we do not forget this struggle and thus perhaps lose what we have gained.
Richard Feynman
There is a need for what [Michael] Polanyi calls the critique of doubt. When we undertake to doubt any statement, we do so on the basis of beliefs which--in the act of doubting--we do not doubt. I can only doubt the truth of a statement on the ground of other things--usually a great many things--which I believe to be true. It is impossible at the same time to doubt both the statement, and the beliefs on the basis of which the statement is doubted.
Lesslie Newbigin
"The Devil is not the Prince of Matter; the Devil is the arrogance of the spirit, faith without smile, truth that is never seized by doubt. The Devil is grim because he knows where he is going, and, in moving, he always returns whence he came."
