“三个代表”思想 ,既在新的历史时期突出了党的先进性问题 ,又结合新的实践丰富发展了无产阶级政党先进性的理论 ,其精髓和灵魂是党的先进性问题。先进性是党的根本性质 ,是党的生命 ,关系到无产阶级政党的生死存亡。党的先进性本质的实现 ,既不是自发的 ,更不是一劳永逸的 ,需要党自觉追求 ,不断努力。 The “three represents” theory not only highlighted the issue of the advanced nature of the party during the new historical period, but also enriched and developed the advanced nature of the proletarian party by combining the new practice. The essence and soul of the “three represents” theory are the issue of the advanced nature of the party. Progressiveness is the fundamental nature of the party and the life of the party, and affects the survival of proletarian parties. The realization of the essence of the advanced nature of the party is neither spontaneous nor even permanent and requires the party’s conscious pursuit and continuous efforts.
