Denis Diderot Quotes

This: That prejudice would pass, and that posterity would pour out the vial of ignominy upon their enemies. O Posterity!

• 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...
• Go further, and require each of them to make a contribution: you will see how many things are still missing, and you will be obliged to get the assistance of a large number of men who belong to different classes, priceless men, but to whom the gates of the academies are nonetheless closed because of their social station. All the members of these learned societies are more than is needed for a single object of human science; all the societies together are not sufficient for a science of man in general.
• If exclusive privileges were not granted, and if the financial system would not tend to concentrate wealth, there would be few great fortunes and no quick wealth. When the means of growing rich is divided between a greater number of citizens, wealth will also be more evenly distributed; extreme poverty and extreme wealth would be also rare.

• There are three principal means of acquiring knowledge available to us: observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination. Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.
• In order to shake a hypothesis, it is sometimes not necessary to do anything more than push it as far as it will go.
• The following general definition of an animal: a system of different organic molecules that have combined with one another, under the impulsion of a sensation similar to an obtuse and muffled sense of touch given to them by the creator of matter as a whole, until each one of them has found the most suitable position for it shape and comfort.

How is this mass to make a transition to a different structure, to sentience, to life? Through heat. And what will produce that heat in it? Motion.

• In any country where talent and virtue produce no advancement, money will be the national god. Its inhabitants will either have to possess money or make others believe that they do. Wealth will be the highest virtue, poverty the greatest vice. Those who have money will display it in every imaginable way. If their ostentation does not exceed their fortune, all will be well. But if their ostentation does exceed their fortune they will ruin themselves. In such a country, the greatest fortunes will vanish in the twinkling of an eye. Those who don't have money will ruin themselves with vain efforts to conceal their poverty. That is one kind of affluence: the outward sign of wealth for a small number, the mask of poverty for the majority, and a source of corruption for all.

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.
