对于刘师培叛变的原因,人们已经作了不少分析。信仰支撑的崩坍,是导致刘师培堕落的又一重要原因。这种支撑,既来自理念,也来自力量;这种力量,既来自组织、同志,也来自朋友、亲人。理论上的简单比附、随意多变导致了他的民主共和理念的破灭。卷入同盟会的纷争,导致他远离了团体和同志;彼此间的龃龉,导致他与最亲密的朋友章炳麟、苏曼殊反目;妻子率先叛变,离他而去。信仰的力量支撑也崩坍了,这一切,最终加速了这个名利欲极旺而又好走极端的青年革命家的堕落。 Liu Shipei mutiny for the reasons, people have made a lot of analysis. The collapsing of belief support is another important reason for the fall of Liu Shipei. This support comes not only from the concept but also from the forces that come from the organizations and from the comrades and from friends and relatives. The simple comparison of theory and the arbitrary change have led to the demise of his concept of democratic republic. Involved in the Union dispute, led him to stay away from the groups and comrades; each other’s shackles, leading him and his closest friends Zhang Binglin, Su Manshu opposition; his wife took the lead in mutiny, leaving him. The power and support of faith also collapsed, all of which eventually accelerated the fall of this famed and prosperous young revolutionary.
