矛盾是唯物辩证法中最核心和实质的问题。从矛盾的存在看,唯物辩证法认为,矛盾存在于一切事物之中,即事事有矛盾;矛盾贯穿于每一个事物发展过程的始终,即时时有矛盾,这就是矛盾的普遍性。矛盾普遍性的特征,要求我们在现实生活中要用“一分为二”的观点看待事情,处理问题。 Contradictions are the core and the essence of materialist dialectics. From the perspective of the existence of contradictions, materialist dialectics argue that contradictions exist in all things, that is, there is contradiction in everything; contradictions run through the development of each thing from start to finish, that is, there are always contradictions. This is the universality of contradictions. The characteristics of the universality of contradictions require that we look at things and deal with problems in our real life from the perspective of “dividing one into two.”
