ETHICS IN RELATION TO CONDUCT
[CHAP.

possible goods can be attained. And (2) these rules, since they can be recommended as a means to that which is itself only a necessary condition for the existence of any great good, can be defended independently of correct views upon the primary ethical question of what is good in itself. On any view commonly taken, it seems certain that the preservation of civilised society, which these rules are necessary effect, is necessary for the existence, in any great degree, of anything which may be held to be good in itself.

96. But not by any means all the rules commonly recognised combine these two characteristics. The arguments offered in defence of Common Sense morality very often presupposes the existence of conditions, which cannot be fairly assumed to be so universally necessary as the tendency to continue life and to desire property. Such arguments, accordingly, only prove the utility of the rule, so long as certain conditions, which may alter, remain the same: it cannot be claimed of the rules thus defended, that they would be generally good as means in every state of society: in order to establish this universal general utility, it would be necessary to arrive at a correct view of what is good or evil in itself. This, for instance, seems to be the case with most of the rules comprehended under the name of Chastity. These rules are commonly defended, by Utilitarian writers who assume as their end the conservation of society, with arguments which presuppose the necessary existence of such sentiments as conjugal jealousy and paternal affection. These sentiments are no doubt sufficiently strong and general to make the defence valid for many conditions of society. But it is not difficult to imagine a civilised society existing without them; and, in such a case, if chastity were still to be defended, it would be necessary to establish that its violation produced evil effects, other than htose due to the assumed tendency of such violation to disintegrate society. Such a defence may, no doubt, be made; but it would require an examination into the primary ethical question of what is good and bad in itself, far more thorough than any ethical writer has ever offered to us. Whether this be so in this particular case or not, it is certain that a distinction, not commonly recognised,
