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.

Figure 2. Dialectical Relation of the Two World.

The objective world we think and talk about is not the real objective world, but is made of our experience, ideas and theories. It is an artificial objective world. For example, when we think of a stone, we think of its round or irregular shape, of its hardness, of its colour being white or grey, and so on. These shapes, hardness, and color are our sensory experience of a certain thing, and the combination of sensory experience makes up an object. The object, which is made up of sensory experience, is often different from the real object. The real stone has a complex composition and structure inside. These objective content is much more than we can think of. So the object world we think and talk about is actually part of the subjective world, it is the objective 2, not the objective world 1.
