Literature, therefore, is a mass of written enlightenment concerning human beings, human hearts, and human thought. Name, if you will, any other study which could better fit a man for grappling with the problems of humanity in that portion of his life which we call public.
But man is something more than a public instrument. We cannot separate the man of citizen life, playing his part in the practical world, from the man of private intercourse, and the man of inward culture and resource. There is a sufficiently "practical" outcome of literary study if it makes the man wiser in himself, if it makes him truer in his judgment, richer and broader in his feelings, makes him put forth antennæ of tact and sympathy, if also it supplies him with such inward resources that he can dispense with unattainable luxuries or with vulgar methods of passing his time. Such results are surely a profoundly useful application of the results of study to life.
Take a human being in the loneliness—the absolute isolation or the intellectual isolation—of the bush; take one who is disabled by illness or disease; take one who is perforce environed all his days by company which is ignoble and dull; take one who can ill afford any of the distractions of the wealthy. How shall he keep alive his higher part, or fill his leisure with contentment and delight, except by constant intercourse with the mightiest minds in the history of the thinking world? Said Rousseau: "Let one destine my pupil to the army, to the church, the bar, or anything else; yet, before his parents have chosen his vocation, nature has called him to the vocation of human life; living is the trade I want to teach him." All the rest is but means to an end. "We live," asserts the poet, "by admiration, hope, and love." And nothing can stimulate these sensations like great literature.
In this connexion I must insist for a few minutes upon the relations of literature to the intellectual idol of to-day—to wit science—science in the popular, if inaccurate, sense. I have to maintain that literature—and particularly poetry—is the indispensable ally and complement of science; that it is, in the end, the means by which the essential truths of science will reach their application to life; that it supplies the force by which the great facts of science are made to operate for good upon our thinking and our feeling. Literature supplies that which science alone cannot supply.
I am aware there are those who fancy that science itself is sufficient guide and equipment for human existence. Huxley, if I remember rightly, asserted in his nonage that science would even afford us a newer and more enlightened morality. But I have never heard any scientist repeat that doctrine; I have never heard any scientist claim that the altruism of the Sermon on the Mount or of Buddha had been superseded by the dry light of scientific conclusions. Physical science and its inventions have not obviously advanced the delicacy of sentiments or of ethical ideas. Chaucer's notion of a "parfit gentil knight," and his "poure parsoun of a toun" could not be bettered for anything discovered in all the five centuries since. It is not easy to see how science can stimulate us to warm-hearted charity, to self-sacrificing love and loyalty, to patriotism, and other manifestations of qualities which we universally recognize as virtues, and as things without which human life would be a dreary and intolerable waste. Without them suicide were almost best. And the cultivation of the emotions belongs to literature, not to objective science.
Will you pardon me if I repeat an illustration which has been used before, though I forget where? There are two ways of regarding tears. They may be the infinitely appealing outward and visible signs of some great inward troubling of the spirit. They may "rise in the heart and gather to the eyes" from "the depths of some divine despair." On the other hand they may be what they were to a certain character in Balzac. The physicist Baltazar retorts in answer to an outburst of tears, "Ah! tears! I have analysed them; they contain a little phosphate of lime, chloride of sodium, mucin, and water!" I do not happen to know if that is a correct analysis, but I do know that both these aspects of tears are true aspects. There is nothing contradictory about them. The one is the aspect of objective science; the other—the human and moral aspect—is that of literature. Is there any doubt which aspect ultimately concerns us the more as human beings, livers of human lives?
There is no conflict between science and literature, especially between science and poetry.
The astronomer tells us the immense distances and immense sizes of the stars—great facts, most interesting facts; but the imagination of literature gets hold of all the vastness and wonder and suggestion of such a universe, and by the gift of expression it makes us realize them, makes us feel an awe and admiration, which may at least lend some chastening to minds which sorely need it. I believe that all true men of science recognise this power of literature, and that they are no more satisfied than the veriest poet with the mere facts of nature without the beauty and marvel and moral stimulation. They do not wish that a flower should be rendered less beautiful because they dissect it and classify it under a hard dog-Latin name. "A primrose by the river's brim a dicotyledon was to him, and it was nothing more." That is not their attitude.
There is not much influence on the higher side of life to be got from a study of nothing else but metals, or nothing else but triangles, or nothing else but germs. But literature exerts a most potent influence on this higher side of life; for it not only supplies thoughts and expresses feelings, but it is in itself—thanks to its expression—a force to make them felt and to give them effective life. It not only instructs—it moves. For, remember, great literature was never produced by cynicism nor by affectation: men of weak convictions or feelings have never been supreme writers. As at Athens, at Rome, or in Elizabethan England, great literature belongs to periods full of animation, of enterprise, of high ideals, of strong aims or strong beliefs. In that prevailing spirit the great writers share, and they impart it forever to us who read. There exhales from what they write an inspiring power of earnestness. As Longinus phrases it, we seem to be possessed by a divine effluence from those mighty minds.
