In order to conceive of science or philosophy as hostile to poetry, we must think of them as building up some barrier between us and the world. But in this respect modern science does not threaten poetry, for it recognises the homogeneity of a material self with a material world; neither does idealism threaten the source of this emotion, regarding the self and the world as both essentially ideal.
The aim of modern thought has been, not to isolate the soul, but rather to give it back to the world of relations. It seems to me that, in so far as Religion has attempted to separate between the Self and things, between God and Man, between the soul and the flesh, Religion has cut at the roots of poetry; but the Religion which attempted this is not, I believe, the religion of the modern world.
Whitman then accepted modern science and philosophy with equanimity, in so far as he understood them, and in their own spheres. Apparent antagonisms between them did not trouble him. They were for him different functions of the one soul. He was too sensible of his own identity and unity in himself to share in the perplexity of those who lose this sense through the exclusive exercise of one or other of their functions. His joint exercise of these proved them to be harmonious. He was unconscious of any quarrel in himself between the scientific and the poetic, the religious and the philosophic faculties.
Definitions in such large matters must generally seem absurd and almost useless, yet here they may be suggestive. If Whitman had formulated his thought he might, perhaps, have said: “Science is the Self probing into the details of the Not-self; Philosophy is the Self describing the Not-self as a Whole; Religion is the attitude of the Self toward the Not-self; and Poetry springs from the passionate realisation of the homogeneity of the Self with the Not-self”.
In such rough and confessedly crude definitions we may suggest, at any rate, a theory for his attitude toward the thought of his day. That thought, it seems unnecessary to add, was impregnated by the positive spirit of science. Names like those of Leibnitz, Lamarck, Goethe, Hegel and Comte remind us that the idea of evolution was becoming more and more suggestive in every field—soon to be enforced anew, and more definitely, by Darwin, Wallace and Spencer. The idea of an indwelling and unfolding principle or energy is the special characteristic of nineteenth century thought; and it has been accompanied by a new reverence for all that participates in the process of becoming. Every form of life has its secret, and is worthy of study, for that secret is a part of the World’s Secret, the Eternal Purpose which affects every soul. We are each a part of that progressive purpose which we call the universe. But we are each absolutely and utterly distinct and individual. Every one has his own secret, his own purpose; in the old phrase, it is to his own master that each one standeth or falleth.
Ideas such as these, the affirmations of a new age, were driving the remnants of the old faiths and the dogmas of the school of Paley into the limbo of the incredible; but they were also casting out the futile atheisms and scepticisms of the dead century. The era of Mazzini, Browning, Ruskin, Emerson, was an era of affirmations, not an era of doubt. And Whitman caught the spirit of his age: eagerly he accepted and assimilated it.
His knowledge of modern thought came to him chiefly through the more popular channels of periodical literature, and through conversations with thoughtful men. Probably the largest and most important part of his reading, then and always, was the daily press. A journalist himself, he had besides an insatiable craving for living facts, and especially for American facts. He wanted to know everything about his country. America was his passion: he understood America. Sometimes he wondered if he was alone in that.
The papers were, indeed, crowded with news of enterprise and adventure. In California, the new territory which Frémont and Stockton had taken from Mexico, gold was discovered in 1848, and in eighteen months a torrent of 50,000 argonauts had poured across the isthmus and over the plains, leaving their trail of dead through the awful grey solitude of the waterless desert. In the summer of ’49 there were five hundred vessels lying in San Francisco harbour,[130] where a few years earlier a single visitor had been comparatively rare. And at the same hour, on the eastern coast, every port was a-clamour with men frantically demanding a passage, and the refrain of the pilgrims’ song was everywhere heard,
Oh, California, that’s the land for me.
