Here Lincoln shows his mental strength. Among all these elements he traced a fundamental similarity. A common pattern embraced them all. The highest and the lowest were essentially alike. All were dowered with kindred capacities for nobility. He never suffered himself or any of his fellowmen to forget his own elevation from lowliest ignorance and poverty to the presidency. However humble, all could rise. However ignorant, all could learn. However unbefriended, all deserved regard. Life and liberty and happiness were a common boon, an even, universal right. For fellowship with God, even when buffeted beneath divine rebukes, all might hope. The ultimate, open possibility of such divine companionship is shown in this last inaugural, where Lincoln's keen discernment avails to comprehend, that even sinning men may, through penitent acceptance of heaven's rebukes, win heaven's favor and walk with God. Thus Lincoln learned and knew that among all men, and between all men and God there was a fundamental ground of imperishable affiance. Here lies the foundation of his philosophy. And this affiance was in its being moral. With him the real was ethical. Pure equity was the primal verity. By character were all things judged. Politics and ethics were identical. In the thought of Lincoln the qualities constituting our American Union, the qualities that defined and contained its very being, the qualities that made it a civic entity, securing to it its coherence and perpetuity, the qualities guaranteeing that it should not dissolve and disappear in the fate and wreck of all decaying things, the qualities that made it worth the faithful care of God and the loving loyalty of men, were identical with the qualities constituting himself a free, responsible soul. The same humble reverence, the same mutual goodwill, the same regard for durability, the same jealousy for integrity as informed his personal conscience and inspired his personal will, should form the law and determine the deeds of the Nation as well, if the Nation was ever to have in its civic being a dignity worthy to survive. Here is a standard conformable at once with the measure of things in heaven, the measure of a Nation, and the measure of every man.
