"He is something far more convincing, far more comforting, far more religiously significant than an optimist: he is a happy man."

Now the supreme value of Browning as an optimist lies in this that we have been examining, that beyond all his conclusions, and deeper than all his arguments, he was passionately interested in and in love with existence. If the heavens had fallen, and all the waters of the earth run with blood, he would still have been interested in existence, if possible a little more so. He is a great poet of human joy for precisely the reason of which Mr. Santayana complains: that his happiness is primal, and beyond the reach of philosophy.

This happiness he finds, as every man must find happiness, in his own way. He does not find the great part of his joy in those matters in which most poets find felicity. He finds much of it in those matters in which most poets find ugliness and vulgarity. He is to a considerable extent the poet of towns. "Do you care for nature much?" a friend of his asked him. "Yes, a great deal," he said, "but for human beings a great deal more." Nature, with its splendid and soothing sanity, has the power of convincing most poets of the essential worthiness of things. There are few poets who, if they escaped from the rowdiest waggonette of trippers, could not be quieted again and exalted by dropping into a small wayside field. The speciality of Browning is rather that he would have been quieted and exalted by the waggonette.

To Browning, probably the beginning and end of all optimism was to be found in the faces in the street. To him they were all the masks of a deity, the heads of a hundred-headed Indian god of nature. Each one of them looked towards some quarter of the heavens, not looked upon by any other eyes. Each one of them wore some expression, some blend of eternal joy and eternal sorrow, not to be found in any other countenance. The sense of the absolute sanctity of human difference was the deepest of all his senses. He was hungrily interested in all human things, but it would have been quite impossible to have said of him that he loved humanity. He did not love humanity but men. His sense of the difference between one man and another would have made the thought of melting them into a lump called humanity simply loathsome and prosaic. It would have been to him like playing four hundred beautiful airs at once. The mixture would not combine all, it would lose all. Browning believed that to every man that ever lived upon this earth had been given a definite and peculiar confidence of God. Each one of us was engaged on secret service; each one of us had a peculiar message; each one of us was the founder of a religion. Of that religion our thoughts, our faces, our bodies, our hats, our boots, our tastes, our virtues, and even our vices, were more or less fragmentary and inadequate expressions.
