The test of all beliefs is their practical effect in life. If it be true that optimism compels the world forward, and pessimism retards it, then it is dangerous to propagate a pessimistic philosophy. One who believes that the pain in the world outweighs the joy, and expresses that unhappy conviction, only adds to the pain. Schopenhauer is an enemy to the race. Even if he earnestly believed that this is the most wretched of possible worlds, he should not promulgate a doctrine which robs men of the incentive to fight with circumstance. If Life gave him ashes for bread, it was his fault. Life is a fair field, and the right will prosper if we stand by our guns. Let pessimism once take hold of the mind, and life is all topsy-turvy, all vanity and vexation of spirit. There is no cure for individual or social disorder, except in forgetfulness and annihilation. “Let us eat, drink and be merry,” says the pessimist, “for to-morrow we die.” If I regarded my life from the point of view of the pessimist, I should be undone. I should seek in vain for the light that does not visit my eyes and the music that does not ring in my ears. I should beg night and day and never be satisfied. I should sit apart in awful solitude, a prey to fear and despair. But since I consider it a duty to myself and to others to be happy, I escape a misery worse than any physical deprivation. Who shall dare let his incapacity for hope or goodness cast a shadow upon the courage of those who bear their burdens as if they were privileges? The optimist cannot fall back, cannot falter; for he knows his neighbor will be hindered by his failure to keep in line. He will therefore hold his place fearlessly and remember the duty of silence. Sufficient unto each heart is its own sorrow. He will take the iron claws of circumstance in his hand and use them as tools to break away the obstacles that block his path. He will work as if upon him alone depended the establishment of heaven on earth. We have seen that the world’s philosophers--the Sayers of the Word--were optimists; so also are the men of action and achievement--the Doers of the Word. Dr. Howe found his way to Laura Bridgman’s soul because he began with the belief that he could reach it. English jurists had said that the deaf-blind were idiots in the eyes of the law. Behold what the optimist does. He controverts a hard legal axiom; he looks behind the dull impassive clay and sees a human soul in bondage, and quietly, resolutely sets about its deliverance. His efforts are victorious. He creates intelligence out of idiocy and proves to the law that the deaf-blind man is a responsible being.
