Panpsychism is a metaphysics, as is physicalism, and they arent put forth as an explanation for split-brains. Graham earlier claimed that splitting/merging of minds is absolutely impossible/ineffable, and rejected panpsychism on those ground. I pointed out that it isnt impossible, since it happens with split-brains. He then acknowledged it is possible, but only with physicalism.DavidMcC wrote:pl0bs wrote:No.It happens in split-brain patients, no? How can you reject panpsychism on such grounds then?Of course. A flock of birds, a storm, a cloud of electrons or a solution of molecules can divide or merge because there is no private internal subjective essence splitting or merging. All that happens is that some go this way and some go that way. The dace varies. In panpsychism we must suppose that the mysterious private subjective that is me is a combination of private subjectives that are not me, that multiple experience of others can become quite different experience for me. How could that possibly work?

AFAIK, panspychism does not restrict itself to split brain patients. Therefore, it should be rejected as an explanation of the behaviour of split-brain patients (or anyone else). Such patients really do have two personalities, sharing one body, because the two brain hemispheres function entirely separately in the absence of the corpus callosum, having their own opinions, etc.
