胡汉民与汪精卫都是民国史上重要的政治人物。他们一生有许多共同之处:他们是同乡,留日时是同学,又是追随孙中山进行民主革命的同志,都深得孙中山的赏识和重用,共同的生活经历曾使他们结成生死与共的挚友。孙中山去世之后,胡、汪二人开始分道扬镳,最终成为不共戴天的政敌。与此同时,胡、汪二人的思想也发生了巨大变化,各自产生了许多不同乃至针锋相对的思想。尤其是九一八事变以来,面对日寇的入侵,胡汉民积极主张抗日,而汪精卫却一步步地沦为大汉奸。本文拟就二人对日寇入侵的态度略作比较,以探讨他们民族主义思想的嬗变及不同之处。 Hu Hanmin and Wang Jingwei are both important political figures in the history of the Republic of China. They have many things in common in their lives. They are fellow countrymen, students in Japan, and followers of Sun Yat-sen for their democratic revolution. Both of them are deeply admired and reused by Sun Yat-sen. Their common life experiences have made them a close friend of life and death. After Sun Yat-sen’s death, Hu and Wang began to part ways and eventually became common political enemies. At the same time, great changes have taken place in the thinking of Hu and Wang, each producing many different and even diametrically opposed ideas. In particular, since the September 18 Incident, in response to the invasion by the Japanese invaders, Hu Hanmin actively advocated resistance to Japan and Wang Jingwei was gradually reduced to a great traitor. This article intends to compare the attitudes of the two against invaders in order to explore the evolution and differences of their nationalist ideologies.
