 In reply, PAP’s defenders might take a cue from contextualists and say that in ordinary contexts, determinism is routinely (and properly) ignored. This would explain why micro-physics never appears in ordinary thinking about responsibility, but in a way compatible with our recognizing PAP’s truth: if determinism were to become salient—as it is in philosophical and scientific contexts—its block of alternatives would cause us to retract our ordinary judgments (cp. Hawthorne 2001). Another option is to say that we ordinarily assume—even if we don’t yet know—that determinism is false (Wiggins 1973: §8), and with this we normally take ourselves to have alternatives. Perhaps if we became determinists, we would stop our practices of praise and blame, or at least stop thinking they were justified, precisely because we endorse PAP or some closely related principle. There is a growing experimental literature on whether we would attribute moral responsibility under the explicit assumption of determinism, but the results so far seem to be mixed (Sommers 2010; Nichols 2015: ch. 4).
