 J. A. Baltimore (2010) has responded by arguing that there are reasons other than that illustrated by the mice tails example for denying efficacy to mental events. M. Baumgartner (2010; see Woodward, 2015 for response) suggests that Shapiro and Sober’s approach depends on a certain (interventionist-inspired) view of causation, but that attributions of causation in virtue of mental properties cannot be counted as making sense without departing from the terms of that view. Whether this strong critique is accepted or not, it is evident that removing a reason for objecting to efficacy of mental events in virtue of their mental properties does not by itself provide a positive reason for asserting such efficacy.
