The human understanding of human beings themselves has always been dominated by abstract views. One can concretely understand and grasp a thing, but whenever one is faced with the object of “human beings”, one unconsciously falls into the trap of abstract views. As is well known, Marx’s philosophy established the concrete view of human beings. One of Marx’s significant contributions is that he discovered the way from the “abstract kingdom” to the “real world” and from “abstract human beings” to “concrete” and actual human beings. According to Engels, Marx’s philosophy is “the science of real human beings and their historical development”. It is indeed strange that the human beings that can understand everything are real and that the human beings to be understood are also real, but human beings are always understood in an abstract way and are reduced to ossified beings such as things.
