In order to achieve great things, we must live as though we were never going to die. - Luc de Clapiers, marquis de Vauvenargues

Superficial knowledge … is hurtful to those who possess true genius; for it necessarily draws them away from their main object, wastes their industry over details and subjects foreign to their needs and natural talent, and lastly does not serve, as they flatter themselves, to prove the breadth of their mind. In all ages there have been men of very moderate intelligence who knew much, and so on the contrary, men of the highest intelligence who knew very little. Ignorance is not lack of intelligence, nor knowledge a proof of genius.

The generality of men are so bound within the sphere of their circumstances that they have not even the courage to get out of them through their ideas, and if we see a few whom, in a way, speculation over great things makes incapable of mean ones, we find still more with whom the practice of small things takes away the feeling for great ones.

La modération des grands hommes ne borne que leurs vices. La modération des faibles est médiocrité.
