On Sleep
Reason directs that we should always go the same way, but not always at the same pace. And, consequently, though a wise man ought not so much to give the reins to human passions as to let him deviate from the right path, he may, notwithstanding, without prejudice to his duty, leave it to them to hasten or to slacken his speed. Could virtue itself put on flesh and blood, I believe the pulse would beat faster going on to assault than in going to dinner. I have taken notice, as of an extraordinary thing, of some great men, who in the highest enterprises and most important affairs have kept themselves in so settled and serene a calm, as not at all to break their sleep.

Michel de Montaigne
