 But if we can account for the moral data on various types of theories, why opt to do so in terms of act-consequentialism rather than non-consequentialism? In other words, why consequentialize rather than, say, Kantianize?

This claim is, of course, controversial, but we’ll address this controversy both in the next section and in  section 4.1  below.
