本文旨在闡述孫中山先生於中華民國成立之後，竭盡所能欲促成國家統一，所發表的一系列言論中，對『統一中國』所堅持的理念。本文首先從其發表的言論中，歸納出他對『統一』的看法和主張，並指出他堅持『民主共和』的主張，無畏於北方軍閥的強大，他認定『民主的中國』才是他一生奮鬥的目標。並試圖以孫中山的立場來看有關『兩岸統一』的問題，盧列孫中山有關『統一』的論述為之論證，『統一』必須以「人民」的最大利益為主導，『統一』必須堅持「民主」與「和平」為手段；民主、和平比統一更重要且更有價值。我們都渴望和平，憎恨戰爭。

This article's purpose is to outline Dr. Sun Yat-sen's discussion and narration on "unification" after Republic of China was founded. He spent his energy on attaining the unification of China. He wrote and published much material on this subject to ensure that unification would be maintained. Firstly, his thesis induced me to ponder on unification. It pointed out his steadfast position on democratic government, without threat from northern military warlords. Dr. Sun concluded that the democratization's China was his life's target. Secondly, the author is attempting, from Sun's viewpoint to discuss unification of China. He illustrates Sun's insistence that the majority would benefits from unification because it results in peace and democracy. So democracy and peace are more important and valuable than unification. We are all desirous of peace, and detest war.
