论中国共产党历史发展主题和主线的革命性与科学性

中国共产党历史发展的主题和主线，贯穿着鲜明的革命性和科学性。这种革命性与科学性不仅有其历史起源，而且以二者相统一为基本特征，集中体现于党的历史发展的主流和本质。革命性与科学性相统一的基本特征在党的历史发展中虽有阶段性差异，但总体上一以贯之。牢牢把握党史主题和主线的革命性与科学性，要着重理解党领导革命、选择社会主义道路的合规律性，正确看待党的历史发展中的失误和曲折，警惕和抵御否定中国革命和中国共产党领导的历史虚无主义思潮。

Revolutionariness and Scientificity of the Theme and Thread in the Historical Development of the Communist Party of China

The theme and thread in the historical development of the Communist Party of China are permeated by distinct revolutionariness and scientificity, which not only have historical origins but also have unity as their bas- ic feature that is embodied in the mainstream and essence of the Party＇ s historical development. Although the basic feature of unity between revolutionariness and scientificity varies in different stages of the Party ＇ s historical develop- ment, it pervades the entire course in general. To solidly grasp the theme and thread of the Party history, we should pay special emphasis to understand the reasonability for the Party to lead the revolution and choose a social- ist path, properly regard the mistakes and errors in the Party＇ s historical development, and keep vigilance against and resist the trend of historical nihilism that negates the revolution in China and the leadership of the Communist Party of China.
