2. How can our principles become dead, unless the impressions [thoughts] which correspond to them are extinguished? But it is in thy power continuously to fan these thoughts into a flame. I can have that opinion about anything which I ought to have. If I can, why am I disturbed? The things which are external to my mind have no relation at all to my mind.—Let this be the state of thy affects, and thou standest erect. To recover thy life is in thy power. Look at things again as thou didst use to look at them; for in this consists the recovery of thy life. 3. The idle business of show, plays on the stage, flocks of sheep, herds, exercises with spears, a bone cast to little dogs, a bit of bread into fishponds, laborings of ants and burden-carrying, runnings about of frightened little mice, puppets pulled by strings—[all alike]. It is thy duty then in the midst of such things to show good humor and not a proud air; to understand however that every man is worth just so much as the things are worth about which he busies himself. 4. In discourse thou must attend to what is said, and in every movement thou must observe what is doing. And in the one thou shouldst see immediately to what end it refers, but in the other watch carefully what is the thing signified.
