Abstract: From five aspects: the "abstract freedom" "here-being freedom" "knowledge freedom" "practical freedom" "aesthetic
freedom", and four categories: pre-cognition—cognition, form—content, static—dynamic, opposing—reunification, this paper
explained the freedom of human being. The realization of human being's freedom is the realization of human's nature and its own value.
The process of consciously and constantly enriching and improving people themselves is the process of ego realization of freedom.
Freedom is the result of ego- presupposition and the inevitability of being human. Freedom is based on the behavioral agent's
relationship of being implemented and already having been realized for contacting there-being and here-being and achieving ego
identity.
