My problem with panpsychism is that its scientifically vacuous. A brain is conscious in an obvious, observable way. An equivalent amount of sand is not. We need an account of why the brain behaves the way that it does, but panpsychism furnishes no such account and the content of that accounting would basically be neuroscience as we know it, including all the philosophical difficulties of why things feel like things at all (this, I feel, is also vacuous, but a different question). Thus panpsychism is of no help at all for explaining anything so what precisely is the point of believing it?
