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 it 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 every way of 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. It is likely that in a society ordered otherwise than our own Lincoln could not have found himself or the path of fame and power upon which he walked serenely to his death. In this place it is right that we should remind ourselves of the solid and striking facts upon which our faith in democracy is founded. Many another man besides Lincoln has served the nation in its highest places of counsel and of action whose origins were as humble as his. Though the greatest example of the universal energy, richness, stimulation, and force of democracy, he is only one example among many. The permeating and all-pervasive virtue of the freedom which challenges us in America to make the most of every gift and power we possess every page of our history serves to emphasize and illustrate. Standing here in this place, it seems almost the whole of the stirring story.
