PAUL M. A. LINEBARGER. December, 1936. INTRODUCTION. The Problem of the _San Min Chu I_. The Materials. Sun Yat-sen played many rôles in the history of his times. He was one of those dramatic and somewhat formidable figures who engage the world’s attention at the very outset of their careers. In the late years of the nineteenth century, he was already winning some renown in the West; it was picturesque that a Cantonese, a Christian physician, should engage in desperate conspiracies against the Manchu throne. Sun became known as a political adventurer, a forerunner, as it were, of such mutually dissimilar personages as Trotsky, Lawrence, and Major-General Doihara. With the illusory success of the revolution of 1911, and his Presidency of the first Republic, Sun ceased being a conspirator in the eyes of the world’s press, and became the George Washington of China. It is in this rôle that he is most commonly known, and his name most generally recalled. After the world war, in the atmosphere of extreme tension developed, perhaps, by the Bolshevik revolution, Sun was regarded as an enigmatic leader, especially significant in the struggle between Asiatic nationalisms allied with the Soviets against the traditional capitalist state-system. It was through him that the Red anti-imperialist policy was pushed to its greatest success, and he was hated and admired, ridiculed and feared, down to the last moments of his life. When he died, American reporters in Latvia cabled New York their reports of Russian comments on the event.(3) More, perhaps, than any other Chinese of modern times, Sun symbolized the entrance of China into world affairs, and the inevitable confluence of Western and Far Eastern history. It is characteristic of Sun that he should have appeared in another and final rôle after his death. He had been thought of as conspirator, statesman, and mass leader; but with the advent of his party to power it became publicly apparent that he had also been a political philosopher. The tremendous prestige enjoyed by him as state-founder and party leader was enhanced by his importance as prophet and law-giver. His doctrines became the state philosophy of China, and for a while his most zealous followers sought to have him canonized in a quite literal fashion, and at one stroke to make him replace Confucius and the Sons of Heaven. After the extreme enthusiasms of the Sun Yat-sen cult subsided, Sun remained the great national hero-sage of modern China. Even in those territories where the authority of his political heirs was not completely effective, his flag was flown and his doctrines taught.
