“Be” in order to “Do” meant a life of equilibrium. Zeal for mission in defiance of the needs of the body produces few results. Writing to the superior of the Aix community, Eugene insists on equilibrium.
The obligation of seven hours of sleep is imposed to remedy. The extravagant piety of certain men who want to serve God as they see fit in defiance of all reason, common sense, justice and enlightened religion. What can a man do, there’s no cure for crackpots. I urge you to order Father Aubert on my behalf never to take less than seven hours sleep. This young priest needs a lot of sleep, he isn’t willing to admit it but it is obviously so. I noticed it a long time ago and others too have made the same observation. I don’t permit any excuses. I positively insist that he submit to this ruling.
Letter to Hippolyte Courtès, 8 September 1836, EO VIII n 582
Good advice for all of us to prevent us becoming crackpots!
