To-day the new science explains the difficulty of right living, by the largeness of man's endowment. There are few failures in the animal or vegetable world. Instinct guides the beast, while the shrub attains its end by automatic processes. No vine was ever troubled to decide whether it should produce grapes or thorns. No fig tree ever had to go to school to learn how to avoid bearing thistles. The humming bird, flying from shrub to shrub, hears the inner voice called instinct. These instincts serve as guide books. The animal creation that moves through the air or water or the forests experiences but little difficulty in finding out the appointed pathway. But the problem of rose, lark or lion is very simple and easy, compared with the problem of man. If the oak must needs bear acorns, man is like a vine that can at will bring forth any one of a hundred fruits. He is like an animal that can at its option walk or fly, swim or run. The pathway opened before the brute world is narrow and its task therefore is very simple, while the vast number of pathways possible to man often embarrasses his judgment and sometimes works bewilderment. After thousands of years man is still ignorant whether it is best for him to eat flesh or confine himself only to fruit; whether the juice of the grape is helpful or harmful; whether the finest culture comes from confining one's study to a single language, as did Socrates and Shakespeare, or through learning many languages, as did Cicero and Milton; whether a monarchy or democracy is better suited for securing the people's happiness and prosperity; whether the love of God in front is a motive sufficient to pull a man heavenward, or whether fear and fire kindled in the rear will not lend greater swiftness to his footsteps. It is wonderful how many problems yet remain to be solved. Nor could it be otherwise. As things increase in size and complexity the difficulty of handling them increases. It is easy to manage a spinning-wheel, but difficult to handle a Jacquard loom having hundreds of delicate parts. It is easy to use a boy's whistle, but hard to master the pipe organ with keys rising bank upon bank. Out of an alphabet numbering six and twenty letters all the sciences and arts can be fashioned; but the alphabet of man's faculties numbers four and forty letters. Who shall measure the divine literatures possible to all these combinations of thought, feeling and aspiration? The scientist tells us that all of the instruments and excellences distributed among the animals are united in man.
