Abstract

The mind is a collection of various classes of processes that can be studied empirically. To limit the field of mental processes we must follow the criteria of folk psychology. There are three kinds of mind: human, animal and mechanical. But the human mind is the paradigm or model of mind. The existence of mechanical minds is a serious challenge to the materialism or the mind-brain identity theory. Based on this existence we can put forward the antimaterialist argument of machines. Intelligence is a class of mental processes such that the mind is the genus and the intelligence is a species of this genus. The capacity to solve problems is a clear and definite criterion of intelligence. Again, like in the mind, the human intelligence is the paradigm of the intelligence. There are also three kinds of intelligence: human, animal and mechanical. Searle’s Chinese room argument is misleading because Searle believes that it is possible to maintain a sharp distinction between syntax and semantics. The reasonable dualism in the brain-mind problem defends the existence of brain-mental processes, physical-mental processes, and nonphysical-mental processes. Constitution of the personal project of life, self-consciousness and free volitions are examples of spiritual processes. Usually the intelligence has been considered the most important quality of human beings, but freedom, or the world of free volitions, is a more specific quality of human beings.
