Few at the North were able to understand the secession movement, most denying that a man at once thoughtful and honorable could join in it. So centralized had the North by 1861 become in all social and economic particulars, that centrality in government was taken as a matter of course. Representing this, the nation was deemed paramount to any state. Governmental sovereignty, like travel and trade, had come to ignore state lines. The whole idea and feeling of state sovereignty, once as potent North as South, had vanished and been forgotten. Far otherwise at the South, where, owing to the great size of states and to the paucity of railways and telegraphs, interstate association was not yet a force. Each state, being in square miles ample enough for an empire, retained to a great extent the consciousness of an independent nation. The state was near and palpable; the central government seemed a vague and distant thing. Loyalty was conceived as binding one primarily to one's own state. It is a misconception to explain this feeling--for in most cases it was feeling rather than reasoned conviction--by Calhoun's teaching. It resulted from geography and history, and, these factors working as they did, would have been what it was had Calhoun never lived. These considerations explain how Colonel Lee, certainly one of the most conscientious men who ever lived, felt bound in duty and honor to side with seceding Virginia, though he doubted the wisdom of her course. Most striking among the characteristics of General Lee which made him so successful was his exalted and unmatched excellence as a man, his unselfishness, sweetness, gentleness, patience, love of justice, and general elevation of soul. Lee much loved to quote Sir William Hamilton's words: "On earth nothing great but man: in man nothing great but mind." He always added, however: "In mind nothing great save devotion to truth and duty." Though a soldier, and at last very eminent as a soldier, he retained from the beginning to the end of his career the entire temper and character of an ideal civilian. He did not sink the man in the military man. He had all a soldier's virtues, the "chevalier without fear and without reproach," but he was glorified by a whole galaxy of excellences which soldiers too often lack. He was pure of speech and of habit, never intemperate, never obscene, never profane, never irreverent. In domestic life he was an absolute model. Lofty command did not make him vain.
