从马克思主义理论视角全面总结分析党性尤其是中国共产党的党性,是开展党性教育,提升党性修养的基础性问题。党性作为政党所固有的本质属性,体现了政党特殊的质的规定性。共产党人集中代表了无产阶级的利益与意志,具有鲜明的阶级性。党性的核心是阶级性。党的先进性、人民性、组织性均建立在其阶级性的基础上。中国共产党作为马克思主义政党,党性的核心同样是阶级性。但由于中国工人阶级除了具有工人阶级的共性外,还具有自身的质的规定性,这使得中国共产党的阶级性,及其先进性、人民性、组织性都有了自身的表现。 To comprehensively analyze and analyze the party spirit, especially that of the CPC, from the perspective of Marxist theory is the basic issue of developing party spirit education and enhancing the party spirit accomplishment. Party nature as the inherent nature of political parties, embodies the special nature of the political parties. The Communists have collectively represented the interests and will of the proletariat and have distinct class. The core of the party spirit is class. The advanced nature, people’s character and organization of the party are based on their class nature. As a Marxist party, the CPC’s core is also a class. However, since the Chinese working class has its own qualitative stipulations in addition to the commonalities of the working class, this makes the CPC’s class nature, its advanced nature, its people’s character and its organizational nature both manifest itself.
