absorb much time, which might be spent to better purpose, is perhaps conclusive against it. So long as men desire to live as strongly as they do, and so long as it is certain that they will continue to do so, anything which hinders them from devoting their energy to the attainment of positive goods, seems plainly bad as a means. And the general practice of murder, falling so far short of universality as it certainly must in all known conditions of society, seems certainly to be a hindrance of this kind.
A similar defence seems possible for most of the rules, most universally enforced by legal sanctions, such as respect of property; and for some of those most commonly recognised by Common Sense, such as industry, temperance and the keeping of promises. In any state of society in which men have that intense desire for property of some sort, which seems to be universal, the common legal rules for the protection of property must serve greatly to facilitate the best possible expenditure of energy. And similarly: Industry is a means to the attainment of those necessaries, without which the further attainment of any great positive goods is impossible; temperance merely enjoins the avoidance of those excesses, which, by injuring health, would prevent a man from contributing as much as possible to the acquirement of these necessaries; and the keeping of promises greatly facilitates cooperation in such acquirement.
Now all these rules seem to have two characteristics to which it is desirable to call attention. (1) They seem all to be such that, in any known state of society, a general observance of them would be good as a means. The conditions upon which their utility depends, namely the tendency to preserve and propagate life and the desire of property, seem to be so universal and so strong, that it would be impossible to remove them; and, this being so, we can say that, under any conditions which could actually be given, the general observance of these rules would be good as a means. For, while there seems to be no reason to think that their observance ever makes a society worse than one in which they are not observed, it is certainly necessary as a means for any state of things in which the greatest
