Query: Toy Models of Top Down Causation   Models in which causation arises from higher level structures as well as from
microdynamics may be relevant to unifying quantum theory with classical physics
or general relativity. They also give a way of defining a form of
panprotopsychist property dualism, in which consciousness and material physics
causally affect one another. I describe toy models based on probabilistic
cellular automata that illustrate possibilities and difficulties with these
ideas.
