Nothing reveals more clearly men’s attitude to learning and literature, and what use they think these are to the State, than the low price they put on them, and their opinion of those who have chosen to practice them.

[Rien ne découvre mieux dans quelle disposition sont les hommes à l’égard des sciences et des belles-lettres, et de quelle utilité ils les croient dans la république, que le prix qu’ils y ont mis, et l’idée qu’ils se forment de ceux qui ont pris le parti de les cultiver.]

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

The Characters [Les Caractères], ch. 12 “Of Opinions [Des Jugements],” § 17 (12.17) (1688) [tr. Stewart (1970)]

[Browne ed. (1752)]

Nothing better demonstrates how men regard science and literature, and of what use they are considered in the State, than the recompense assigned to them, and the idea generally entertained of those persons who resolve to cultivate them.
