Mind-body dualism is generally considered the central question in the philosophy of mind. The problem with mind-body dualism is that it is unclear whether the mind is actually a separate entity from the human body, as Descartes says in his argument, or whether the mind is the brain itself. Descartes believed that in a person there were two major components, the physical body and the non-physical body called the spirit or soul. As a scientist, Descartes believed in mechanical theories of matter, but he was also very religious and did not believe that people could simply be mechanical creatures functioning like a "clock." So it was Descartes who argued that the mind directs thoughts. To explain this, he divided the world into two parts, the scientific world and the mental world. The scientific world was everything physical, like the human body. The mental world was the mind that could neither be seen nor touched. Thus, mind-body dualism was created. If the spirit could not be seen or touched, how could it interact with the human body and therefore how could we know if it existed? Furthermore, how would we know if other minds exist if we cannot make contact with other minds? Questions like these are what made Descartes' version of dualism improbable and led to different theories of mind such as physicalism, which is the belief that the mind is simply the result of brain states such as nerve impulses in certain areas of the brain. Dualism is true and minds are not physical, so it is impossible for us to contact the minds of others. We assume that if another person behaves the same way we do, then they must have a mind. This could be troublesome because, according to Turing, machines may soon be able to imitate human behavior...... middle of paper ..., which would be very likely. If AIs were used in this way, wouldn't it be considered slavery since the AIs would have a mind? In an episode of Star Trek, entitled Data, a man wants to dismantle an automaton equipped with artificial intelligence to learn how to recreate it and mass produce it. By mass-producing the automaton, he wants to create an army of AIs to use in dangerous missions that would save human lives but put the AIs in danger. This example once again shows how AIs would be forced to fight for the human race at their own risk. The possibility of AI also challenges people's religious beliefs. If an AI has a mind and a conscience, then we will have to ask whether or not it has a soul according to religious belief. If it is decided that AIs have souls, then they will have the chance to go to heaven or any other form of afterlife.?
