 In formulating his harm principle, Feinberg is careful to qualify his central claim with conditions relating to what would be “effective” and of what the “cost” may be to “other values”. Not so, however, when he formulates legal moralism. This may be no more than an oversight. However, considerations of the sort—potential “effectiveness”, “cost to other values”—are central to legal moralists as will be seen in the next section (Devlin 1965; Moore 1997: 663–665). Stressing these, as regards the harm principle, but omitting them, as regards legal moralism, leaves the unfair impression that the former has a subtlety and a realism that the latter lacks. Furthermore, Feinberg’s formulation makes wrongdoing or immorality sound like something of an afterthought or a factor of only marginal importance to the criminalization question. The legal moralist by contrast sees wrongdoing or immorality not as marginal or in play only after harm and offence have had their due, but as central or pivotal. Wrongs, as Devlin would have it, “shape” crimes. Of the best known—murder, rape, battery, theft, fraud, arson—so called mala in se—we should say “a moral idea shapes the content of the law” (Devlin 1965: 27). It is true, the moralist will say, that while these crimes are shaped by morality, the criminal offence of, say, murder is not identical to the moral wrong of murder as law will import various other requirements, of legality and so on; for example the law
