Let us confess that man easily masters every other art and science. His discoveries as to stars and stones and shrubs provoke ever fresh surprise. His inventions, who can number? He easily masters winds and rivers. He takes the sting out of the thunderbolt and makes it harmless. Afterward with electric lamps he illumines towns. With invisible sunbeams he paints instantaneous pictures of faces, palaces, mountains, and landscapes. With the dark X-rays he photographs the bone incased in flesh, the coins contained in the purse. With his magnet the scientist throws a rope around the cathode rays and drags them whithersoever he will. In the field the inventor uses an electric hoe to kill the germs of the thistle and deadly nightshade. Strange that he cannot invent an instrument for killing the germs of hatred and envy in his own heart! The gardener easily masters the art of cultivating roses and violets, but breaks down in trying to produce in himself those beauteous growths called love, truth, justice--flowers, these, that are rooted in heaven, but blossom here on earth. An expert driver will hold the reins over six fiery steeds, or even eight, but he descends from his coach to find that his own passions are steeds of the sun that run away with him, bringing wreckage and ruin. Man has skill for turning poisons into medicines. He changes deadly acids into balms, but he has no skill for taking envy's poisons out of the tongue, or sheathing the keen sword of hatred. As to physical nature, man seems rapidly approaching the time when all the forces of land and sea and sky will yield themselves as willing and obedient servants to do his will. But, having made himself monarch in every other realm, man breaks down utterly in attempting the task of living peaceably with his friends and neighbors. Sublime in his integrity and strength, he is most pitiable in the way he wrecks his own happiness, and ruins the happiness of others. Pestilence in the city, tornado in the country, the fire in the forest--these are but feeble types of man as a destroyer. One science is as yet unmastered by man--the science of right living and the art of getting along smoothly with himself and his fellows.
