Not to be able to bear with all bad-tempered people with whom the world is crowded, shows that a man has not a good temper himself: small change is as necessary in business as golden coin.

[Ne pouvoir supporter tous les mauvais caractères dont le monde est plein n’est pas un fort bon caractère: il faut dans le commerce des pièces d’or et de la monnaie.]

Jean de La Bruyère (1645-1696) French essayist, moralist

The Characters [Les Caractères], ch. 5 “Of Society and Conversation [De la Société et de la Conversation],” § 37 (5.37) (1688) [tr. Van Laun (1885)]

We must bear with some peoples bad Characters, as we do with bad Money, for the benefit of Commerce.
[Bullord ed. (1696)]

Not to be able to bear with all the bad Characters the World is full of, is no good Character: Copper Mony, for the sake of Commerce, is necessary as well as Gold and Silver.
[Curll ed. (1713)]

We must bear with some Peoples ill Tempers, as we do with Copper Money, for the benefit of Commerce.
[Browne ed. (1752)]

To be unable to endure all the unpleasant characters of whom the world is full is not an admirable characteristic: we need, in our dealings, both gold coins and small change.
[tr. Stewart (1970)]
