what appear to us monstrous acts of cruelty, were dictated by that very feeling of humanity, the universal perception of the merit of which they are cited to disprove,(117) and even when this is not the case, all that can be inferred is, that the standard of humanity was very low. But still humanity was recognised as a virtue, and cruelty as a vice. At this point, I may observe how completely fallacious is the assertion that a progressive morality is impossible upon the supposition of an original moral faculty.(118) To such statements there are two very simple answers. In the first place, although the intuitive moralist asserts that certain qualities are necessarily virtuous, he fully admits that the degree in which they are acted upon, or in other words, the standard of duty, may become progressively higher. In the next place, although he refuses to resolve all virtue into utility, he admits as fully as his opponents, that benevolence, or the promotion of the happiness of man, is a virtue, and that therefore discoveries which exhibit more clearly the true interests of our kind, may throw new light upon the nature of our duty. The considerations I have urged with reference to humanity, apply with equal force to the various relations of the sexes. When the passions of men are altogether unrestrained, community of wives and all eccentric forms of sensuality will be admitted. When men seek to improve their nature in this respect, their object will be to abridge and confine the empire of sensuality. But to this process of improvement there are obvious limits. In the first place the continuance of the species is only possible by a sensual act. In the next place the strength of this passion and the weakness of humanity are so great, that the moralist must take into account the fact that in all societies, and especially in those in which free scope had long been given to the passions, a large amount of indulgence will arise which is not due to a simple desire of propagating the species. If then incest is prohibited, and community of wives replaced by ordinary polygamy, a moral improvement will have been effected, and a standard of virtue formed. But this standard soon becomes the starting-point of new progress. If we examine the Jewish law, we find the legislator prohibiting adultery, regulating the degrees of marriage, but at the same time authorising polygamy, though with a caution against the excessive multiplication of wives. In Greece monogamy, though not without exceptions, had been enforced, but a concurrence of unfavourable influences prevented any high standard being attained among the men, and in their case almost every form of indulgence beyond the limits of marriage was permitted. In Rome the standard was far higher. Monogamy was firmly established. The ideal of female morality was placed as high as among Christian nations. Among men, however, while unnatural love and adultery were regarded as wrong, simple unchastity before marriage was
