Reading Aristotle and applying his notion of philia, or political friendship, across 26 centuries sheds significant light into Abraham Lincoln’s career. It is precisely in Lincoln’s embodiment of the Aristotelian notion of friendship that we come to understand his unique greatness. Perhaps he alone of all Americans proved capable of such extraordinary feats as leading the Republican party to victory in 1860, holding the Union together through the secession crisis and four long years of bloody civil war, ending slavery without white backlash, and offering reconciliation with the incredible magnanimity expressed in the ringing phrases of the Second Inaugural address. The basis of Lincoln’s preternatural political genius proved to be his ability to comprehend all sides, a comprehension that can only come from a profound belief in the importance of friendship. Americans, Lincoln argued throughout a terrible war as he had his entire life, were not enemies but friends who shared a commitment to nature and nature’s law as expressed in the Declaration.
