The Problem of Massive Deception for Justification Norms of Action
In this paper, I argue against recent versions of justification norms of action and practical deliberation (Neta, Noûs 43:684–699, 2009; Gerken, Synthese 178:529–547, 2011, Synthese 189:373–394, 2012; Smithies, Noûs 46:265–288, 2012). I demonstrate that these norms yield unacceptable results in deception cases. However, a further modification of justification norms in the light of these results appears to be ad hoc. Hence, I claim, we should reject justification norms of action and practical deliberation.
