Gideon Yaffe's Attempts is a masterfully executed philosophical investigation of what it means to attempt something. Yaffe is obviously motivated by the fact that the criminal law punishes attempted crimes, and he believes that his philosophical analysis can shed light on and be used to criticize the law's understanding of those crimes. I focus exclusively on the relevance of Yaffe's philosophical analysis of attempts to the criminal law of attempts. I assume that Yaffe's account of what it is to attempt (...) something is basically correct and ask whether the criminal law uses in the way Yaffe uses it, and whether it should use Yaffe's conception of an attempt. I conclude that a lot of criminal-law doctrine, including, very importantly, the influential Model Penal Code's treatment of attempts, is inconsistent with Yaffe's conception of attempts. Because Yaffe is principally interested in what it means to attempt something rather than in the criminal law's treatment of attempts, I believe he misanalyzes the problem of factual versus legal impossibility. And Yaffe's chapter on inherently impossible attempts concludes by positing a quite paradoxical type of criminal attempt, one that is indeed an attempt but for which the defendant should not be convicted because the evidence of its commission is insufficient. I find Yaffe's argument to this effect opaque and therefore unconvincing. (shrink)
