MIND vs. BODY

So I have intro to philosophy every Monday, Wednesday and Friday and 10am in the morning. Its crazy. SOme things that we talk about I don't really agree with but not because I have anything to disprove it, just because I believe differently. To be more specific, our teacher is pretty biased when it comes to religion, (to say he's a strong disbeliever) and it doesn't really bother me, I just wish I could know enough, or have enough logic to argue with him. But its impossible, and I don't even try. So we talk about some crazy things. For example right now were talking about how mind and body may or may not be two separate entities. Our professor uses an example of a zombie and a ghost to illustrate. To start, God can create anything that we can think of. So if we can fathom a mind with no body, like ghost, it should be God should be able to create it..right? Can we fathom a body with no soul? The argument sort of reminds me of the excerpt that I used a while back in one of my entries. In the East of Eden Cathy is characterized as being a sort of monster. She is a body lacking soul. She is not lacking a brain. A brain is different. She is lacking a soul. So I do think its possible to lack a mind. Scary...but possible. More broadly put, the argument is labeled Dualism vs. Materialism. Materialism is the theory that everything can be simplified to some sort of physical state. So we can understand everything totally by just studying it. Dualism theorizes the opposite. It states that it is not possible to understand everything by just observing it objectively. An example in the Dualists favor uses a character Frank. Frank can see one more color than anyone else. When observing tomatoes, he claims he sees two different color reds. No one else can see it. He separates the fruits consistently, putting the tomatoes in two different groups every time he asked to resort. Although we know everything about colors, and we know that Frank can see an extra one, there is a missing piece to an outsider's understanding of it. We do not understand how the color makes Frank feel. There is something about the color's effect on one's experiences that we do not know. Therefore Physicalism/Materialism has a missing piece and is not functional.
Anyways, those are just some arguments we have been reviewing. Im no philosopher so sorry if you don't follow.
