An exclusion problem for epiphenomenalist dualism

The chief motivation for epiphenomenalist dualism is
its promise to solve dualism's causal exclusion problem without inducing causal overdetermination or
violations of the causal closure of the physical. This
paper argues that epiphenomenalist dualism is itself
susceptible to an exclusion problem. The problem
exploits symmetries of determination and influence
generated by a wide class of physical theories. Further,
I argue that there is an interference effect between
solving epiphenomenalist dualism's exclusion problem
and using epiphenomenalist dualism as a solution to
the causal exclusion problem. What emerges is an
overlooked, empirically motivated challenge to
epiphenomenalist dualism.
