In exploring humanized education, researchers tend to look at education problems from the perspective of anti-humanization, without a further analysis of the concept of anti-humanized education. The difference among anti-humanization, dehumanization and weak humanization in education is obscure. Using the category of purpose-means, we seek to reveal and clarify the connotation of the three, their boundaries and interrelationships. We argue that the core of the anti-humanized education is domestication of education, which violates humanity; while the core of dehumanized education is the materialization of education, which is separate from humanity; and the core of weak humanization is alienation of education, which deviates from humanity. Therefore, education should develop towards truth-breaking away from the fetters of domestication, towards harmony-evading the snare of materialization, and towards freedom-getting rid of the fence of alienation.
