I am indebted to Joseph Boyle and Antony Duff for their comments on an earlier draft of this paper. They saved me from many (if not all) errors and infelicities.

A. Donagan’s objection to the Principle, that “the doctrine underlying all forms of the theory of the double effect is that what lies outside the scope of a man’s intentions in acting does not belong to his action, and so is not subject to moral judgement,” The Theory of Morality (Chicago: University of Chicago Press, 1977) at 164, is surely incorrect.Google ScholarPubMed

39. To forestall any misunderstanding, let me emphasize that my talk of “balancing” here in no way implies any commitment to consequentialism (any more than does the notion of “proportionate reason” for the Principle of Double Effect; see Boyle, , supra, note 23 at 528, n. 7).Google Scholar

42. To avoid this (to him undesirable) consequence, Finnis would redefine murder to include “doing without lawful justification or excuse an act which one is sure will kill.” Supra, note 35 at 49.

43. By the “circumstances” of an action is meant any state of affairs which the agent neither brings about, nor intends to bring about, by that action, but which in some way forms (part of) the context of that action; see Donagan, , supra, note 23 at 39–40;Google Scholar Duff, , supra, note 25 at 42.Google Scholar

This test is, of course, simply the counterfactual test of intention applied to circumstances. Fletcher presents this test not as a test of intention but as “providing an account of what ordinary people mean when they talk about ‘trying’ or ‘attempting’ to do something.” Fletcher, G., Rethinking Criminal Law (Boston: Little, Brown, 1978) at 161.Google Scholar

As Fletcher recognizes, the test of rational motivation “points in the direction of liability” in the case of attempted murder by voodoo, although the “consensus of Western legal systems is that there should be no liability”, ibid, at 166. However, I believe that liability can be excluded by using the rule of proximity; see “Attempting the Impossible (Again)” (1983) 25 Criminal Law Quarterly 294 at 300–02.Google Scholar
