自由主义者以抽象的教条看待马克思主义的原则。他们赞成马克思主义，但是不准备实行之，或不准备完全实行之，不准备拿马克思主义代替自己的自由主义。这些人，马克思主义是有的，自由主义也是有的：说的是马克思主义，行的是自由主义；对人是马克思主义，对己是自由主义。两样货色齐备，各有各的用处。这是一部分人的思想… - Mao Zedong

Wide, wide flow the nine streams through the land,
Dark, dark threads the line from south to north.

人们要想得到工作的胜利即得到预想的结果，一定要使自己的思想合于客观外界的规律性，如果不合，就会在实践中失败。人们经过失败之后，也就从失败取得教训，改正自己的思想使之适合于外界的规律性，人们就能变失败为胜利，所谓“失败者成功之母”，“吃一堑长一智”，就是这个道理。
