Davidson’s views are widely known rather than widely accepted, I think. I don’t recall seeing them beign used
for a serious argument for epiphenomenalism, I can see how they could be, if you tie causality to laws. OTOH,
I can see how you could argue in the opposite direction: if mental events are identical to physical events, then, by Leibnitz’s law, they have the same causal powers as physical events.
