Out of this discussion Mr. Duncan evolved the copy line, "The success of a life is in direct proportion to its net contribution to human happiness," and Dave sat writing it far into the night.
As soon as Dave had learned to read a little Mr. Duncan took him one day to the public library, and the young man groped in amazement up and down the great rows of books. Presently a strange sense of inadequateness came over him. "I can never read all of those books, nor half of them," he said. "I suppose one must read them in order to be well informed."
Mr. Duncan appeared to change the subject.
"When you go into a fruit store do you stand and say, 'I can never eat all of that fruit; crates and crates of it, and carloads more in the warehouse?' Of course you don't. You eat enough for the good of your system, and let it go at that. Now, just apply the same sense to your reading. Read enough to keep your mind fresh, and alert, and vigorous; give it one new thought to wrestle with every day, and let the rest go. . . Oh, I know that there is a certain school which holds that unless you have read this author or that author, or this book or that book, you are hopelessly uninformed or behind the times. That's literary snobbery. Let them talk. A mind that consumes more than it can assimilate is morally on a par with a stomach that swallows more than it can digest. Gluttons, both of them. Read as much as you can think about, and no more. The trouble with many of our people is that they do not read to think, but to save themselves the trouble of thinking. The mind, left to itself, insists upon activity. So they chloroform it."
Mr. Duncan also took occasion to speak with Dave about his religious views. He did not forget Dave's explanation of why he went out of the church. "I sympathize with your point of view a great deal," he said, "but don't be too sweeping in your conclusions. The church is too fussy over details; too anxious to fit the mind of man--which is his link with the Infinite--into some narrow, soul-crushing creed; too insistent upon the form of belief and not nearly insistent enough upon conduct. It makes me think of a man who was trying to sell me an automobile the other day. He was explaining all about the trimmings; the cushions and the lights and the horn and all that sort of stuff, and when he was through I said, 'Now tell me something about the motor. I want to know about the thing that makes the wheels go round. If it's no good I guess the trimmings are only fit for junk.' Well, that's the way with the church. The motor that has kept it running for nineteen centuries is the doctrine of love; love of man to man, love of man to God, love of God to man. Nothing about wrath--that's only a back-fire--but love. Without that motor all the trimmings are junk. Each sect has its own trimmings, but they all profess to use the same motor. . . Still, the motor is all right, even if it is neglected and abused. I don't think you'll find a better, and you must have power of some kind."
