Leon of After Nature gives a detailed defense.
I plan to critique him, particularly on the point of emergence. I expect that he already knows what I am going to say, but I think that the exercise will be productive for both of us. Moreover, one of my first thoughts was that his description of panpsychism makes it sound like he is accepting dualism without admitting it. Leon, be thinking about that, as I suspect you will have time to give a counter to that argument before I can raise a predictable critique.
