10 Denis Diderot Quotes on Truth

Denis Diderot quotes on truth

4. Only a very bad theologian would confuse the certainty that follows revelation with the truths that are revealed. They are entirely different things.

18. The more man ascends through the past, and the more he launches into the future, the greater he will be, and all these philosophers and ministers and truth-telling men who have fallen victims to the stupidity of nations, the atrocities of priests, the fury of tyrants, what consolation was left for them in death? This: That prejudice would pass, and that posterity would pour out the vial of ignominy upon their enemies. O Posterity! Holy and sacred stay of the unhappy and the oppressed; thou who art just, thou who art incorruptible, thou who findest the good man, who unmaskest the hypocrite, who breakest down the tyrant, may thy sure faith, thy consoling faith never, never abandon me!

19. Pithy sentences are like sharp nails which force truth upon our memory.

31. On doit exiger de moi que je cherche la verite, mais non que je la trouve.

36. Scepticism is the first step towards truth.

42. 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...

47. In order to shake a hypothesis, it is sometimes not necessary to do anything more than push it as far as it will go.

61. We swallow greedily any lie that flatters us, but we sip only little by little at a truth we find bitter.

80. How easy it is to tell tales!

94. Of course it would not do for the church to allow a man to die in peace who had added to the intellectual wealth of the world. The moment Diderot was dead, Catholic priests began painting and recounting the horrors of his expiring moments. They described him as overcome with remorse, as insane with fear; and these falsehoods have been repeated by the Protestant world, and will probably be repeated by thousands of ministers after we are dead. The truth is, he had passed his threescore years and ten. He had lived for seventy-one years. He had eaten his supper. He had been conversing with his wife. He was reclining in his easy chair. His mind was at perfect rest. He had entered, without knowing it, the twilight of his last day. Above the horizon was the evening star, telling of sleep. The room grew still and the stillness was lulled by the murmur of the street. There were a few moments of perfect peace. The wife said, 'He is asleep.' She enjoyed his repose, and breathed softly that he might not be disturbed. The moments wore on, and still he slept. Lovingly, softly, at last she touched him. Yes, he was asleep. He had become a part of the eternal silence.
