Book Three, Chapter 44
Of not Drawing to Ourselves Exterior Things

In many things it behooves you to be ignorant, and to esteem yourself as dead upon earth, and as one to whom the whole world is crucified....It is more profitable to turn away your eyes from such things as displease you, and leave to every one his own way of thinking, than to give loose to contentious discourses....That which is of little or no profit takes up our thoughts, and that which is necessary above all is negligently passed over; for the whole man sinks down into outward things, and unless he quickly recovers himself, he willingly continues immersed in exterior things.
