Knowledge has come into the world in vain if it is not to emancipate those who may have it from narrowness, censoriousness, fussiness, an intemperate zeal for petty things. It would be a most pleasant, a truly humane world, would we but open our ears with a more generous welcome to the clear voices that ring in those writings upon life and affairs which mankind has chosen to keep. Not many splenetic books, not many intemperate, not many bigoted, have kept men’s confidence; and the mind that is impatient, or intolerant, or hoodwinked, or shut in to a petty view shall have no part in carrying men forward to a true humanity, shall never stand as examples of the true humankind. What is truly human has always upon it the broad light of what is genial, fit to support life, cordial, and of a catholic spirit of helpfulness. Your true human being has eyes and keeps his balance in the world; deems nothing uninteresting that comes from life; clarifies his vision and gives health to his eyes by using them upon things near and things far. The brute beast has but a single neighborhood, a single, narrow round of existence; the gain of being human accrues in the choice of change and variety and of experience far and wide, with all the world for stage—a stage set and appointed by this very art of choice—all future generations for witnesses and audience. When you talk with a man who has in his nature and acquirements that freedom from constraint which goes with the full franchise of humanity, he turns easily with topic to topic; does not fall silent or dull when you leave some single field of thought such as unwise men make a prison of. The men who will not be broken from a little set of subjects, who talk earnestly, hotly, with a sort of fierceness, of certain special schemes of conduct, and look coldly upon everything else, render you infinitely uneasy, as if there were in them a force abnormal and which rocked toward an upset of the mind; but from the man whose interest swings from thought to thought with the zest and poise and pleasure of the old traveler, eager for what is new, glad to look again upon what is old, you come away with faculties warmed and heartened—with the feeling of having been comrade for a little with a genuine human being. It is a large world and a round world, and men grow human by seeing all its play of force and folly. VI
