They believe in combing the two principles and speak of a theory that of central state of mind that makes some aspects of the human mind immaterial. The emotions and the advanced development of the humans are due to advancements in the mechanical body owing to evolution. This reasoning of the mind and the so-called intuition is due to the facts garnered from various sources that people encounter. There has been a lot of debate between science and philosophy. The philosophers argue that mind cannot be confined by the regular science. The scientist and doctors say that this there is mechanical reasoning behind every thought and emotion. For every phenomenon there is viable scientific reasoning. This further proves the existence of the mechanical mind. If it cannot be explained right away it does not mean the reason is not behind the certain event. The central state of mind amalgamates the concepts of behaviorism, mechanical principles of the body and dualism. But when every emotion experienced by the human body can be accounted bythe principles of science the concept that mind is an immaterial mind seems unlikely. This is why there is general criticism of the immaterial mind theory. Immaterial theory is not a plausible theory as scientific notions rather it is derived from sources that do not exist.
