Context

“it lets me not an hour alone, sleeping or waking, but is always preaching to me death, patience, and repentance. I now defend myself from temperance, as I have formerly done from pleasure; it draws me too much back, and even to stupidity. Now I will be master of myself, to all intents and purposes; wisdom has its excesses, and has no less need of moderation than folly. Therefore, lest I should wither, dry up, and overcharge myself with prudence, in the intervals and truces my infirmities allow me: “Mens intenta suis ne seit usque malis.” [“That my mind may not eternally be intent upon my ills.”” source
