Certitude is not the test of certainty. We have been cocksure of many things that were not so.
Oliver Wendell Holmes

FEU. Dieu d'Abraham, Dieu d'Isaac, Dieu de Jacob, non des philosophes et savants. Certitude. Certitude. Sentiment. Joie. Paix.
Blaise Pascal
Religious people often say that religion offers absolute certainty about right and wrong; 'god tells them' what it is. Even supposing that the aforementioned gods exist, and that the believers really know what the gods think, that still does not provide certainty, because any being no matter how powerful can still be wrong. Whether gods exist or not, there is no way to get absolute certainty about ethics. Without absolute certainty, what do we do? We do the best we can. Injustice is happening now; suffering is happening now. We have choices to make now. To insist on absolute certainty before starting to apply ethics to life decisions is a way of choosing to be amoral.
Richard M. Stallman
In our worship of certainty we must distinguish between the sound certainty and the sham, between what is gold and what is tinsel; and then, when certainty is attained, we must remember that it is not the only good; that we can buy it at too high a price; that there is danger in perpetual quiescence as well as in perpetual motion; and that a compromise must be found in a principle of growth.
Benjamin N. Cardozo
...human beings have religious needs. They have a need for a feeling of certitude in their minds about things they cannot control and they do not fully understand, and with humility, they admit they do not understand...
Carroll Quigley
I have approximate answers and possible beliefs in different degrees of certainty about different things, but I'm not absolutely sure of anything, and of many things I don't know anything about, but I don't have to know an answer. I don't feel frightened by not knowing things, by being lost in the mysterious universe without having any purpose which is the way it really is as far as I can tell possibly. It doesn't frighten me.
Richard Feynman
