Denis Diderot: Man

“Man was born to live with his fellow human beings. Separate him, isolate him, his character will go bad, a thousand ridiculous affects will invade his heart, extravagant thoughts will germinate in his brain, like thorns in an uncultivated land.”

Denis Diderot

The character Suzanne Simon, in La Religieuse [The Nun] (1796)

“The more man ascends through the past, and the more he launches into the future, the greater he will be”

Denis Diderot

As quoted in "Diderot" in The Great Infidels (1881) by Robert Green Ingersoll; The Works of Robert G. Ingersoll Vol. III (1900), p. 367
Context: 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!

“We are constantly railing against the passions; we ascribe to them all of man’s afflictions, and we forget that they are also the source of all his pleasures”

Denis Diderot book Philosophical thoughts

As translated in Diderot (1977) by Otis Fellows, p. 39
Variant translations:
One declaims endlessly against the passions; one imputes all of man's suffering to them. One forgets that they are also the source of all his pleasures.
Only passions, great passions, can elevate the soul to great things.
Pensées Philosophiques (1746)
Source: Pensées philosophiques
Context: We are constantly railing against the passions; we ascribe to them all of man’s afflictions, and we forget that they are also the source of all his pleasures … But what provokes me is that only their adverse side is considered … and yet only passions, and great passions, can raise the soul to great things. Without them there is no sublimity, either in morals or in creativity. Art returns to infancy, and virtue becomes small-minded.

“Every man has his dignity. I'm willing to forget mine, but at my own discretion and not when someone else tells me to.”

Forgetting

“If your little savage were left to himself and be allowed to retain all his ignorance, he would in time join the infant’s reasoning to the grown man’s passion, he would strangle his father and sleep with his mother.”

“There is no kind of harassment that a man may not inflict on a woman with impunity in civilized societies.”

"On Women" (1772), as translated in Selected Writings (1966) edited by Lester G. Crocker

“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.”

“What a hell of an economic system! Some are replete with everything while others, whose stomachs are no less demanding, whose hunger is just as recurrent, have nothing to bite on. The worst of it is the constrained posture need puts you in. The needy man does not walk like the rest; he skips, slithers, twists, crawls.”

“No man has received from nature the right to give orders to others. Freedom is a gift from heaven, and every individual of the same species has the right to enjoy it as soon as he is in enjoyment of his reason.”

Denis Diderot

Aucun homme n'a recu de la nature le droit de commander aux autres. La liberté est un présent du ciel, et chaque individu de la meme espèce a le droit d'en jouir aussitòt qu'il jouit de la raison.

“I am beginning to feel that I am growing old; soon, I shall have to eat mush like children. I shall no longer be able to speak, which will be a rather great advantage for others and but a small inconvenience for myself. … The time in which I count in years is gone; that in which I count in days is here. … I had thought that the fibers of the heart would grow callous with age, it's not at all the case. I am not sure that my sensitivity hasn't increased; everything moves me, affects me. … To fade out between a man feeling your pulse and another bothering your head; not to know where one comes from, why one came, where one is going …”

“Although a man may wear fine clothing, if he lives peacefully; and is good, self-possessed, has faith and is pure; and if he does not hurt any living being, he is a holy man.”
