In the exposition just foregoing, the thought has been drawn into allusions to Lincoln's premonitions or aspirations towards immortality, for the Union, if not for himself. This was in the course of an effort to find the spring-head of his kindliness. And it culminated in the suggestion that deep within Lincoln's being there was enshrined an assurance, however unconfessed or even half unconscious, of personal immortality. And that from within this shrine of living hope, common to him with every man, he drew his inspiration and his very pattern of a national Union and a national peace that would endure forever. Here is something that calls for examination, for in this we touch a radical quality of Lincoln's moral being. This eager craving after permanence was in him an appetite that could never be fed or satisfied by any things that perish. In itself and in its nutriment there is an irrepealable call for something indefeasable, something utterly superior to all fear of death, something never amenable to any form of dissolution or decay, something spiritually pure, and essentially kindred to the essential being of a deathless soul. The matter may be approached to start with by saying some things negatively. Lincoln was centrally in no sense a materialist. He was indeed firmly sensitive to the physical majesties of this continent, though in his day they were hardly half disclosed. He calculated with carefulness our material capacities for expansion in power and wealth. He foresaw our certain outward growth into a puissant Nation, the coveted and ample resort and refuge and home of hordes of men from other lands. In his own well-seasoned and resourceful physique he felt and knew the worth of physical virility. He could thoughtfully compute the glittering values, the goodly financial revenues, the days and months and total seasons of physical idleness and delights that accrue to human owners from the unrequited toil of human slaves. And in the current civil war he completely understood that no less a concern than the perpetuity of the American Union was pending upon contests largely consisting of encounters of physical prowess, of tests of muscular endurance and strength.
