I was really responding to what you failed to write, i.e. a relevant response to my comment. The point is that it doesn't matter if you use the words "eternal soul," "ontologically basic mental state," or "minds are Forms"; none of those ideas matches up with reality. The position most strongly supported by the evidence is that minds, mental states, etc. are produced by physical brains interacting with physical phenomena. We dismiss those other ideas because they're unsupported and holding them prevents the realization that you are a brain, and the universe is physical.

It seems like you're arguing that we ought to take ideas seriously simply because people believe them. The fact of someone's belief in an idea is only weak Bayesian evidence by itself, though. What has more weight is why ey believes it, and the empirical evidence just doesn't back up any concept of souls.
