It seems to be a wise provision of nature that the follies of men should be short-lived; but books interfere and immortalize them. A fool, not content with having bored all those who have lived with him, insists on tormenting generations to come; he would have his folly triumph over oblivion, which should have been as welcome to him as death; he wishes posterity to be informed of his existence, and he would have it remember for ever that he was fool.

[La nature sembloit avoir sagement pourvu à ce que les sottises des hommes fussent passagères, et les livres les immortalisent. Un sot devroit être content d’avoir ennuyé tous ceux qui ont vécu avec lui : il veut encore tourmenter les races futures, il veut que sa sottise triomphe de l’oubli, dont il auroit pu jouir comme du tombeau; il veut que la postérité soit informée qu’il a vécu, et qu’elle sache à jamais qu’il a été un sot.]

Charles-Lewis de Secondat, Baron de Montesquieu (1689-1755) French political philosopher

Commonly paraphrased as "An author is a fool who, not content with having bored those who have lived with him, insists on boring future generations."

Nature seems wisely to have provided that the Follies of Men shou'd pass away, but Books perpetuate them. A Fool ought to be satisfy'd with having teaz'd those who liv'd at the same Time with him: but he is for going further, and is resolved to plague the Generations to come he is resolv'd to make his Impertinence triumph over Oblivion, which he might have enjoy'd as well as his Grave: he will have Posterity know that such a one liv'd, and all future Ages be inform'd that he was a Fool.
[tr. Ozell (1736 ed.), Letter 64]

Nature seems to have provided, that the follies of men should be transient, but they by writing books render them permanent. A fool ought to content himself with having wearied those who lived with him: but he is for tormenting future generations; he is desirous that his folly should triumph over oblivion, which he ought to have enjoyed as well as his grave; he is desirous that posterity should be informed that he lived, and that it should be known for ever that he was a fool.
[tr. Floyd (1762)]

Nature has wisely provided that the follies of men should be ephemeral; but, unhappily, these very follies are immortalised in books. A fool ought to have been satisfied with boring all those who have lived with him; yet he insists on torturing future races; he is determined that his folly shall triumph over the oblivion in which he ought to have been able to find as much enjoyment as he does in his last slumber; he wishes posterity to know that he has lived, and remember forever that he was a fool.
[tr. Betts (1897)]

While nature seems wisely to have provided that the stupidities of men should be transient, books immortalize them. A fool should be content with boring everyone who has lived with him, but he further undertakes to torment future generations. He wants his folly to triumph over the oblivion which he should welcome like the sleep of the tomb; he wants to inform posterity that he has lived, and to have it forever remembered that he was a fool.
[tr. Healy (1964)]

Nature in her wisdom seems to have arranged for man's follies to be short-lived, and books render them immortal. A fool ought to be satisfied with having bored all his own contemporaries, but he also seeks to torment those as yet unborn; he wants his stupidity to triumph over oblivion, which he might, like the tomb, have enjoyed; but no, he wants posterity to be notified that he has lived, and he wants her to know, for all eternity, that he was an idiot.
[tr. Mauldon (2008), Letter 64]

Nature has so arranged things that the absurdities men say are passing things, but books give them immortal life. A fool ought to have been content to have annoyed those who live near him, but instead he wants the chance to torment future generations. He wants his absurdities to triumph over the complete oblivion that he really ought to have welcomed and enjoyed like a tomb. He wants posterity to be informed that he lived, and he wants it known for all time that he was a fool.
[tr. MacKenzie (2014), Letter 64]
