Never Renounce.—Renouncing the world without knowing it, like a nun, results in a fruitless and perhaps melancholy solitude. This has nothing in common with the solitude of the vita contemplativa of the thinker: when he chooses this form of solitude he wishes to renounce nothing; but he would on the contrary regard it as a renunciation, a melancholy destruction of his own self, if he were obliged to continue in the vita practica. He forgoes this latter because he knows it, because he knows himself. So he jumps into his water, and thus gains his cheerfulness.
