Russellian Monism and Epiphenomenalism

Contemporaries often reject epiphenomenalism (EPI) out of hand, while Russellian Monism (RM) is regarded as worthy of further development. It is argued here that this difference of attitudes is indefensible, because the easy rejection of EPI is due to its violating a certain Causal Intuition, and RM implicitly violates that same intuition. An enriched version of RM mitigates the violation, but the same mitigation results if we make a parallel enrichment of EPI. If RM and EPI are approached on a level playing field, it is not obvious which will prove to be the better view.
