Not long after his return home he was stricken with serious sickness. The disease was not of such a character that it was expected to prove fatal, but the highest medical skill and most tender nursing were unavailing. The truth was, although unsuspected, that his vital energies were completely exhausted by the enormous labors and deep agitations of the past ten years. He had just passed his 48th birthday but was already gray and prematurely old. He had dwelt amid the tempest for twenty years and had felt more of severe strain than most men who had seen the Psalmist's three score years and ten. When told that his end was near, and asked what message he would send to his boys: "Tell them," he said, "to obey the laws and support the Constitution of the United States." On the morning of June 3rd he died. His remains lie buried in Chicago on the shore of Lake Michigan, a spot fitly chosen as the last resting place of this most ceaselessly active and inexhaustibly resourceful of American statesmen. History has not been kind to Douglas. The farther we recede from events the more trivial seem the temporary circumstances which influence them and the clearer appear the changeless principles which ought to mold men's conduct. But to the eager, impetuous man of action, the temporary circumstances are apt to be of overmastering force. He was a practical man of action, whose course was generally guided by the accidental circumstances of the hour, rather than by fixed principles. His education was defective. He entered the great arena with little of either mental or moral culture. Yet, severely as we now judge him, he did not fall below the prevailing standard of political morals. His real sin was that he did not rise above the ethics of the times; that he remained deaf as an adder to the voices of the great reformers who sought to regenerate the age, and who were compelled to grapple with him in deadly struggle before they could gain footing on the stage. The time was out of joint and he felt no vocation to set it right. While his ethics has fared hard, his mental gifts have been over-estimated. The availability of all his resources, his overwhelming energy and marvelous efficiency among men of intellect, gave rise to the impression which still survives that he was a man of original genius. But of all his numerous speeches, heard or read by millions, not a sentence had enough vitality to survive even one generation. Though for ten years of stormy agitation he was the most commanding figure in our public life and wielded power of which Presidents and Cabinets stood in awe, the things for which he is chiefly remembered are his unfortunate doctrine of popular sovereignty and the resistless power with which he defended his most dubious relation to the question of slavery.
