Value is the core concept in the Philosophy of Value. I think that value is the human being itself and self-realization. Value can be divided into the value itself and the valuable things. The human being itself and self-realization are the value itself, and those things, which are valuable to human being itself and self-realization are valuable things. The value itself is the core that the Philosophy of Value specializes in, and the valuable things are the objects that the Philosophy of Value specializes in.
