There is nothing useful to be read about panpsychism. It is admitted by its proponents that there is no evidence for the idea and no evidence against it. There is also no possible way to ever provide any evidence for or against it. It is an unprovable hypothesis and therefore it is by definition 'not even wrong'.
If I propose that an invisible unicorn lives silently in my garage how much time would an intelligent person spend trying to prove I was wrong? Panpsychism is exactly like that. It does absolutely nothing to help us understand human consciousness. It is a pointless distraction.
