As quoted in "J. Robert Oppenheimer" by L. Barnett, in Life, Vol. 7, No. 9, International Edition (24 October 1949), p. 58; sometimes a partial version (the final sentence) is misattributed to Marcel Proust.
Context: There must be no barriers to freedom of inquiry … There is no place for dogma in science. The scientist is free, and must be free to ask any question, to doubt any assertion, to seek for any evidence, to correct any errors. Our political life is also predicated on openness. We know that the only way to avoid error is to detect it and that the only way to detect it is to be free to inquire. And we know that as long as men are free to ask what they must, free to say what they think, free to think what they will, freedom can never be lost, and science can never regress.

“It is better to keep your mouth shut and appear stupid than to open it and remove all doubt.”

Variant: It is better to keep your mouth closed and let people think you are a fool than to open it and remove all doubt.

Widely known as The Prayer of St. Francis, it is not found in Esser's authoritative collection of Francis's writings.
[Fr. Kajetan, Esser, OFM, ed., Opuscula Sancti Patris Francisci Assisiensis, Rome, Grottaferrata, 1978]. Additionally there is no record of this prayer before the twentieth century.
[Fr. Regis J., Armstrong, OFM, Francis and Clare: The Complete Works, New York, Paulist Press, 1982, 10, 0-8091-2446-7]. Dr. Christian Renoux of the University of Orleans in France traces the origin of the prayer to an anonymous 1912 contributor to La Clochette, a publication of the Holy Mass League in Paris. It was not until 1927 that it was attributed to St. Francis.

Luther's Latin: “Nullus ex patribus, quorum infinitus est numerus, de Sacramento sic loquutus est, ut Sacramentarii. Nam nemo ex iis talibus verbis utitur Tantum panis & vinum est: Vel Corpus & Sanguis Christi non adestProfecto non est credibile, nec possibile cum toties ab iis res ista agatur & repetatur, quod non aliquando, vel semel tantum excidissent haec verba. Est merus Panis, aut, non quod Christi corpus corporaliter adsit, aut his similia, cum tamen multum referat ne homines seducantur, Sed omnes praecise ita loquuntur, quasi nullus dubitet, quin ibi praesto sit corpus & sanguis Christi. Sane ex tot patribus, & tot scriptis, ab aliquibus, vel saltem ab uno potuisset negativa sententia proferri, ut in aliis articulis usitatum & frequens est, si non sensissent, corpus & sanguinem Christi vere inesse. Verum omnes concordes & constantes uno ore affirmatium proferunt.” See Luther's Opera Omnia, Wittenberg ed., (1558), vol., 7, p. 391. http://books.google.com/books?id=jrpjO-K_kQYC&pg=PR10&dq=Accipitae+Hoc+%22corpus+meum%22+luther&hl=en&ei=9iFBTeOqIonbgQeJ4IXmAQ&sa=X&oi=book_result&ct=result&resnum=1&ved=0CCkQ6AEwAA#v=onepage&q=coenae&f=false

Context: My friend has said to me that I am a poor hand to quote Scripture. I will try it again, however. It is said in one of the admonitions of our Lord, "As your Father in Heaven is perfect, be ye also perfect." The Saviour, I suppose, did not expect that any human creature could be perfect as the Father in Heaven; but He said, "As your Father in Heaven is perfect, be ye also perfect." He set that up as a standard; and he who did most toward reaching that standard, attained the highest degree of moral perfection. So I say in relation to the principle that all men are created equal, let it be as nearly reached as we can. If we cannot give freedom to every creature, let us do nothing that will impose slavery upon any other creature. Let us then turn this Government back into the channel in which the framers of the Constitution originally placed it. Let us stand firmly by each other. If we do not do so we are turning in the contrary direction, that our friend Judge Douglas proposes — not intentionally — as working in the traces tend to make this one universal slave nation. He is one that runs in that direction, and as such I resist him. My friends, I have detained you about as long as I desired to do, and I have only to say, let us discard all this quibbling about this man and the other man; this race and that race and the other race being inferior, and therefore they must be placed in an inferior position; discarding our standard that we have left us. Let us discard all these things, and unite as one people throughout this land, until we shall once more stand up declaring that all men are created equal. My friends, I could not, without launching off upon some new topic, which would detain you too long, continue to-night. I thank you for this most extensive audience that you have furnished me to-night. I leave you, hoping that the lamp of liberty will burn in your bosoms until there shall no longer be a doubt that all men are created free and equal.

"Reflections on Gandhi" (1949)
Context: I could see even then that the British officials who spoke of him with a mixture of amusement and disapproval also genuinely liked and admired him, after a fashion. Nobody ever suggested that he was corrupt, or ambitious in any vulgar way, or that anything he did was actuated by fear or malice. In judging a man like Gandhi one seems instinctively to apply high standards, so that some of his virtues have passed almost unnoticed. For instance, it is clear even from the autobiography that his natural physical courage was quite outstanding: the manner of his death was a later illustration of this, for a public man who attached any value to his own skin would have been more adequately guarded. Again, he seems to have been quite free from that maniacal suspiciousness which, as E. M. Forster rightly says in A Passage to India, is the besetting Indian vice, as hypocrisy is the British vice. Although no doubt he was shrewd enough in detecting dishonesty, he seems wherever possible to have believed that other people were acting in good faith and had a better nature through which they could be approached.

Article on Philosophy, Vol. 25, p. 667, as quoted in Main Currents of Western Thought : Readings in Western European Intellectual History from the Middle Ages to the Present (1978) by Franklin Le Van Baumer
Variant translation: Reason is to the philosopher what grace is to the Christian. Grace moves the Christian to act, reason moves the philosopher. Other men walk in darkness; the philosopher, who has the same passions, acts only after reflection; he walks through the night, but it is preceded by a torch. The philosopher forms his principles on an infinity of particular observations. … He does not confuse truth with plausibility; he takes for truth what is true, for forgery what is false, for doubtful what is doubtful, and probable what is probable. … The philosophical spirit is thus a spirit of observation and accuracy.
L'Encyclopédie (1751-1766)
Context: Reason is to the philosopher what grace is to the Christian.
Grace causes the Christian to act, reason the philosopher. Other men are carried away by their passions, their actions not being preceded by reflection: these are the men who walk in darkness. On the other hand, the philosopher, even in his passions, acts only after reflection; he walks in the dark, but by a torch.
The philosopher forms his principles from an infinity of particular observations. Most people adopt principles without thinking of the observations that have produced them, they believe the maxims exist, so to speak, by themselves. But the philosopher takes maxims from their source; he examines their origin; he knows their proper value, and he makes use of them only in so far as they suit him.
Truth is not for the philosopher a mistress who corrupts his imagination and whom he believes to be found everywhere; he contents himself with being able to unravel it where he can perceive it. He does not confound it with probability; he takes for true what is true, for false what is false, for doubtful what is doubtful, and probable what is only probable. He does more, and here you have a great perfection of the philosopher: when he has no reason by which to judge, he knows how to live in suspension of judgment...
The philosophical spirit is, then, a spirit of observation and exactness, which relates everything to true principles...

The Value of Science (1955)
Context: 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 darn 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.

As quoted in Words from the Wise : Over 6,000 of the Smartest Things Ever Said (2007) by Rosemarie Jarski, p. 312
Context: I doubt if a single individual could be found from the whole of mankind free from some form of insanity. The only difference is one of degree. A man who sees a gourd and takes it for his wife is called insane because this happens to very few people.
