A reductionistic and physicalistic understanding concerning consciousness - An explanatory framework

This article brings a new perspective on understanding consciousness, and it is an attempt to establish a reductionistic and physicalistic explanatory framework. It strives from two directions: (1) By studying the features of consciousness, we can formulate a theoretical model for consciousness. (2) Consciousness is existence, therefore, by asking what is existence in the physical world, we can distinguish three kinds of existence, by excluding the less feasible two of these three kinds, we can narrow the scope of research and focus on one of them. By figuring out the possible physical foundation, we can establish a concrete model to match the features of the theoretical model of consciousness. Base on this model, many phenomena can also be explained, such as, who or what am “I” (the self), why there is “something it is like”, What is the difference between conscious and unconscious, why digital computer cannot be conscious, etc.
