Abstract

Paul Ramsey has argued that the rule of double effect is morally significant because of the existence of indeterminate choices between incommensurable values. I interpret his argument as the following disjunctive syllogism. There are two sorts of principles we can appeal to in dealing with indeterminate choices: the rule of double effect and a commensurate reason principle. The second does not work, so we are left with the first. I respond, first, that this argument commits the fallacy of bifurcation and second, that for all Ramsey has shown, and surprisingly, a commensurate reason principle can deal with indeterminate choices.
