The present is not a fitting occasion to examine, with any completeness, the causes that led to the Proclamation of Emancipation; but the peculiar relation of that act to the character of Abraham Lincoln cannot be understood, without considering one remarkable fact in his history. His earlier years were passed in a region remote from the centers of political thought, and without access to the great world of books. But the few books that came within his reach he devoured with the divine hunger of genius. One paper, above all others, led him captive, and filled his spirit with the majesty of its truth and the sublimity of its eloquence. It was the Declaration of American Independence. The author and the signers of that instrument became, in his early youth, the heroes of his political worship. I doubt if history affords any example of a life so early, so deeply, and so permanently influenced by a single political truth, as was Abraham Lincoln's by the central doctrine of the Declaration,--the liberty and equality of all men. Long before his fame had become national he said, "That is the electric cord in the Declaration, that links the hearts of patriotic and liberty-loving men together, and that will link such hearts as long as the love of freedom exists in the minds of men throughout the world."
