We have found that our great philosophers and our great men of action are optimists. So, too, our most potent men of letters have been optimists in their books and in their lives. No pessimist ever won an audience commensurately wide with his genius, and many optimistic writers have been read and admired out of all measure to their talents, simply because they wrote of the sunlit side of life. Dickens, Lamb, Goldsmith, Irving, all the well-beloved and gentle humorists, were optimists. Swift, the pessimist, has never had as many readers as his towering genius should command, and indeed, when he comes down into our century and meets Thackeray, that generous optimist can hardly do him justice. In spite of the latter-day notoriety of the "Rubáiyát" of Omar Khayyám, we may set it down as a rule that he who would be heard must be a believer, must have a fundamental optimism in his philosophy. He may bluster and disagree and lament as Carlyle and Ruskin do sometimes; but a basic confidence in the good destiny of life and of the world must underlie his work.
Shakespeare is the prince of optimists. His tragedies are a revelation of moral order. In "Lear" and "Hamlet" there is a looking forward to something better, some one is left at the end of the play to right wrong, restore society and build the state anew. The later plays, "The Tempest" and "Cymbeline," show a beautiful, placid optimism which delights in reconciliations and reunions and which plans for the triumph of external as well as internal good.
If Browning were less difficult to read, he would surely be the dominant poet in this century. I feel the ecstasy with which he exclaims, "Oh, good gigantic smile o' the brown old earth this autumn morning!" And how he sets my brain going when he says, because there is imperfection, there must be perfection; completeness must come of incompleteness; failure is an evidence of triumph for the fulness of the days. Yes, discord is, that harmony may be; pain destroys, that health may renew; perhaps I am deaf and blind that others likewise afflicted may see and hear with a more perfect sense! From Browning I learn that there is no lost good, and that makes it easier for me to go at life, right or wrong, do the best I know, and fear not. My heart responds proudly to his exhortation to pay gladly life's debt of pain, darkness and cold. Lift up your burden, it is God's gift, bear it nobly.
