Full Idea
The only form of interactionist dualism that has seemed even remotely tenable in the contemporary picture is one that exploits certain properties of quantum mechanics.
Gist of Idea
Maybe dualist interaction is possible at the quantum level?

A Reaction
I think he is bluffing. No doubt quantum mechanics offers many intriguing possibilities, such as the interaction of many worlds within the mind, but I am not aware that anything non-physical is ever postulated. Physicists don't deal in the non-physical.
