“I'm investigating people who sacrifice trained killers to dark gods.
Perfect, it will keep him occupied.
In what capacity?
Bait.”

Context: He who suffers time to slip away and does not grow in virtue the more one thinks about him the sadder one becomes. No man has a capacity for virtue who sacrifices honour for gain. Fortune is powerless to help one who does not exert himself. That man becomes happy who follows Christ. There is no perfect gift without great suffering. Our triumphs and our pomps pass away; gluttony and sloth and enervating luxury have banished every virtue from the world; so that as it were wandering from its course our nature is subdued by habit. Now and henceforth it is meet that you cure yourself of laziness. The Master has said that sitting on down or lying under the quilts will not bring thee to fame. He who without it has frittered life away leaves no more trace of himself upon the earth than smoke does in the air or the foam on the water.
