As you know biologists (atheist, physicalists, darwinists) have held to their dogma of strong physicalism and MUST deny epiphenomenalism. Once they go to epiphenominalism they have crossed the breach to the metaphysical. Yet to fail to embrace, at least, epiphenomenalism, is to refuse to acknowledge their own consciousness, logic, reason and rational thought. ( and much, much more). To be on the horns of that delima must be the metaphysical equivalent of an ivory enema (if you have ever ridden bulls, you know the joke).
I don't have to be a bull rider to grasp how unpleasant it must be to be on the wrong end of an "ivory enema."
Thank you ever so much, dear Texas Songwriter, for your trenchent (and hilarious) observations!
