In Chinese, Xin means the heart, here it refers to the thought in the brain. The thought includes perceptual thinking and rational thinking. Xing refers to human nature, needs and interests. Nature includes human temper, disposition, habits, character, cultivation, sentiment and spirit. Qing includes emotion, feeling and vision. Feeling includes bitterness, joy, happy, anger, sorrow, fear, love, evil, surprise, worry and so on. Feeling is the main driving force to produce the will of behavior. When people’s feelings develop into passions, it will produce the biggest driving force to behavior, and people will burst out with great creativity, fighting power or destructive power. Emotion is relatively short feeling, including anxiety, excitement, panic, satisfaction, pride, etc. Vision is relatively rational feeling, such as wish, dream, ideal, yearning, and so on. Yi means the direct power that governs people’s behavior, including people’s attitude, will, perseverance and decision-making. Moral ideas belong to attitude or will. Decisions include concrete decisions and abstract decisions. All normative theories are abstract decisions, including technology, principles, laws, regulations, systems, ethics, customs, etc.

Thought products include knowledge, hypotheses, assumptions, fantasy, myths, fairy tale, lies, arts, religion, prejudice, and so on. Among them, knowledge includes experience, ideas and theories. Experience includes both direct experience and indirect experience. Direct experience includes direct experience of external things and experience of subjective world of one’s own body and mind, in which there are many illusions. Ideas include opinions, prejudices, hypotheses, assumptions, impressions, and half-baked ideas. Theories include scientific theories, philosophical theories, and all kinds of fallacies. Experience, idea and theory describe abstract Matter and Tao. Knowledge is the most objective consciousness, all other consciousness are less objective or no objective. Knowledge creates an objective world, which can be called objective world 2, knowledge is the content of objective world 2.

In the subjective world, the Xing of people (nature, needs, interests) and emotion are the id; the feeling, thought, attitude, will, decision, experience and idea are the ego; the vision and science, art, religion of thought products are the superego.

4. Dialectical Relation of Two Worlds

There are the sun, the moon, the stars, tables, chairs and human society in the objective world. And there is the human brain, the movement of brain and the consciousness generated by brain movement. Human consciousness produces the subjective world, in which there is what I see and think. I see tables and chairs, I see people and their behaviors, I see the sun, the moon and the stars, I think of the Big Bang, I think of the wave-particle duality of light and so on. These things constitute the objective world, which is inside the subjective world. This objective world is objective world 2. The real objective world is objective world 1.
