That's an assertion.
I deposit those in the trash, so to speak. They have no conviction.
You noted that the brain can be artificially manipulated by another human (doctor/scientist). From this, I gathered you also knew that that the person whose brain was being manipulated to move a body part, or to talk, might say, amazed, "But I didn't do that."
No doubt that the body part moved. Everyone saw it, but "I" (the person whose brain was being manipulated) didn't do it. Gives one pause, does it not? Maybe worth considering before tossing it into the trash?
Look, I am betting we both agree that there is a humongous amount we don't know. For that reason, I do not think we should limit the field of knowledge to matter and to what can be measured by the five senses. Science itself baldly states it does not know what happens to conscience after death; that it does not know i whether the brain is the generator or if it is the receptor--there is no way of telling. (And doesn't the 'artificial' tests argue for it being a receptor of signals as well as the transmitter of signals?) In any case, because we do not know, this sends us into the field of philosophy, and both sides of the philosophy are worth considering in our educational system.
