保持党的先进性问题，从来就是党的建设的核心问题。马克思主义认识论告诉我们，客观事物和反映客观事物的观念形态都是具体的历史的，而不是抽象的、一成不变的。党的先进性也是如此。时代前进了，世界变化了，我们对党的先进性的认识也要发展和深化，否则，就会陷入盲目性， Maintaining the advanced nature of the party has always been the core issue of party building. Marxist epistemology tells us that objective things and the notion of ideas that reflect objective things are concrete historical rather than abstract and immutable. The same is true of the advanced nature of the party. The times have advanced and the world has changed. Our understanding of the advanced nature of the party must also be developed and deepened. Otherwise, we will fall into blindness.
