Abstract
Central to Gideon Yaffe's powerful theory of the legitimate criminalization of unsuccessful attempts is his according to which, I argue that this principle, taken together with Yaffe's theory of the nature of attempts, threatens to lead to a normatively problematic conclusion in support of the legitimate criminalization of attempts that are merely a matter of thinking and do not involve action in the public space. And I argue that Yaffe's efforts to block this conclusion are themselves problematic. This leads to a proposed revision of the one that draws on plausible normative views about the nonlegitimacy of criminal sanctions in cases of attempts that are merely a matter of thinking and do not involve action in the public space
