Here, no less, hides the mystery of democracy. Who shall guess this secret of nature and providence and a free polity? Whatever the vigor and vitality of the stock from which he sprang, its mere vigor and soundness do not explain where this man got his great heart that seemed to comprehend all mankind in its catholic and benignant sympathy, the mind that sat enthroned behind those brooding, melancholy eyes, whose vision swept many an horizon which those about him dreamed not of—that mind that comprehended what he had never seen, and understood the language of affairs with the ready ease of one to the manner born—or that nature which seemed in its varied richness to be the familiar of men of everyday life. This is the sacred mystery of democracy, that its richest fruits spring up out of soils which no man has prepared and in circumstances amidst which they are the least expected. This is a place alike of mystery and of reassurance.
