The traveller, as he opened his Saturday Review upon his return to London, and read the current essay on Whitman, would have been faced by a problem fit to puzzle Montesquieu, a problem to floor Goethe. And yet Whitman is representative. He is a real product, he has a real and most interesting place in the history of literature, and he speaks for a class and type of human nature whose interest is more than local, whose prevalence is admitted,--a type which is one of the products of the civilization of the century, perhaps of all centuries, and which has a positively planetary significance. There are, in every country, individuals who, after a sincere attempt to take a place in organized society, revolt from the drudgery of it, content themselves with the simplest satisfactions of the grossest need of nature, so far as subsistence is concerned, and rediscover the infinite pleasures of life in the open air. If the roadside, the sky, the distant town, the soft buffeting of the winds of heaven, are a joy to the aesthetic part of man, the freedom from all responsibility and accountability is Nirvana to his moral nature. A man who has once tasted these two joys together, the joy of being in the open air and the joy of being disreputable and unashamed, has touched an experience which the most close-knit and determined nature might well dread. Life has no terrors for such a man. Society has no hold on him. The trifling inconveniences of the mode of life are as nothing compared with its satisfactions. The worm that never dies is dead in him. The great mystery of consciousness and of effort is quietly dissolved into the vacant happiness of sensation,--not base sensation, but the sensation of the dawn and the sunset, of the mart and the theatre, and the stars, the panorama of the universe. To the moral man, to the philosopher or the business man, to any one who is a cog in the wheel of some republic, all these things exist for the sake of something else. He must explain or make use of them, or define his relation to them. He spends the whole agony of his existence in an endeavor to docket them and deal with them. Hampered as he is by all that has been said and done before, he yet feels himself driven on to summarize, and wreak himself upon the impossible task of grasping this cosmos with his mind, of holding it in his hand, of subordinating it to his purpose. The tramp is freed from all this. By an act as simple as death, he has put off effort and lives in peace. It is no wonder that every country in Europe shows myriads of these men, as it shows myriads of suicides annually. It is no wonder, though the sociologists have been late in noting it, that specimens of the type are strikingly identical in feature in every country of the globe.
