Another block of stumbling, about which much has been written, is Emerson’s optimism, which rests upon the belief that evil is negative, merely the privation or shadow of good, without real existence. It was the heresy of “Uriel” that there was nothing inherently and permanently bad: no line of division between good and evil—“Line in nature is not found”; “Evil will bless and ice will burn.” He turned away resolutely from the contemplation of sin, crime, suffering: was impatient of complaints of sickness, of breakfast-table talk about headaches and a bad night’s sleep. Doubtless had he lived to witness the Christian Science movement, he would have taken an interest in the underlying doctrine, while repelled by the element of quackery in the practice and preaching of the sect. Hence the tragedy of life is ignored or evaded by Emerson. But _ici bas_, the reality of evil is not abolished, as an experience, by calling it the privation of good; nor will philosophy cure the grief of a wound. We suffer quite as acutely as we enjoy. We find that all those disagreeable appearances—“swine, spiders, snakes, pests, mad-houses, prisons, enemies,”—which he assures us will disappear, when man comes fully into possession of his kingdom, do not disappear but persist. The dispute between optimism and pessimism rests, in the long run, on individual temperament and personal experience, and admits of no secure solution. Imposing systems of philosophy have been erected on these opposing views. Leibnitz proved that everything is for the best in the best of all possible worlds. Schopenhauer demonstrated the futility of the will to live; and showed that he who increaseth knowledge increaseth sorrow. Nor does it avail to appeal from the philosophers to the poets, as more truly expressing the general sense of mankind; and to array Byron, Leopardi, Shelley, and the book of “Lamentations,” and “The City of Dreadful Night” against Goethe, Wordsworth, Browning, and others of the hopeful wise. The question cannot be decided by a majority vote: the question whether life is worth living, is turned aside by a jest about the liver. Meanwhile men give it practically an affirmative answer by continuing to live. Is life so bad? Then why not all commit suicide? Dryden explains, in a famous tirade, that we do not kill ourselves because we are the fools of hope:— When I consider life, ’tis all a cheat . . . Shelley, we are reminded, calls birth an “eclipsing curse”; and Byron, in a hackneyed stanza, invites us to count over the joys our life has seen and our days free from anguish, and to recognize that whatever we have been, it were better not to be at all. The question as between optimist and pessimist is not whether evil is a necessary foil to good, as darkness is to light—a discipline without which we could have no notion of good,—but whether or not evil predominates in the universe. Browning, who seems to have had somewhat of a contempt for Bryon, affirms:—
