Read another response about Mind
Hello, My name is Kyle, I'm a physics student. I have zero training in philosophy, save for an introductory philosophy course in my freshman year. I've been thinking about something quite frequently, and would like to hear an opinion from somebody who is knowledgable in the subject; The mind and the ego is a construct of the brain( at least as far as I know), and it's experiences. And I think it's fair to say that the brain is a clever organization of atoms, in what is essentially a computer. It has memories, which I think forms the ego, in a seemingly contiguous storyline. The hardware of the brain is however constantly changing, with atoms being lost and gained, through cell death, reproduction, respiration, and other biochemical functions, and yet our subjective experience remains. Suppose this effect is recreated in hypothetical setting where it is possible to create an exact replica of a person(A) to an artificially constructed person (b). Now, the copy is an exact replica, with every electrochemical charge in the brain at their respective locations. The copy(b) would be finishing the thought that person (a) was thinking at the start of the process, with every memory in place. Suppose the process kills person (a) leaving only person (b) who feels as if nothing happened. This process is analogous to the natural biochemical exchange discussed before. This thought experiment leaves me a bit puzzled as to the implications on the ego and subjective experience. If anyone could derive a conclusion, I would love to hear.
