Lecture Abstract

At the beginning of the investigation of consciousness, we need to remind ourselves of what we already know.

1. Consciousness, (subjective, qualitative, intentionalistic and unified) really exists as a real part of the biological world. It cannot be eliminated or reduced to something else.
2. All conscious states are caused by lower-level neuronal processes in the brain.
3. Consciousness is realized in the brain as a higher-level or system feature.
4. Consciousness functions causally in producing the behavior of conscious organisms.

Confusions about these four are common and derive from a set of mistaken assumptions. The main sources of the mistakes are the traditional dualistic vocabulary of mental and physical, the ambiguous concept of reduction, the traditional (from Hume) conception of causation and the concept of identity. Once we get over the obstacles created by these confusions, we will not have solved the problem of consciousness, but we will at least have removed some of the major obstacles to its solution.
