Doctrines like these, if consistently carried out, would have utterly destroyed so much of morality as depends on the social sanction; while, by inculcating the absolute indifference of external actions, they might ultimately have paralysed the individual conscience itself. But the Stoics were not consistent. Unlike some modern moralists, who are ready to forgive every injury so long as they are not themselves the victims, our philosophers were unsparing in their denunciations of wrong-doing; and it is very largely to their indignant protests that we are indebted for our knowledge of the corruption prevalent in Roman society under the Empire. It may even be contended that, in this respect, our judgment has been unfairly biassed. The picture drawn by the Stoics, or by writers trained under their influence, seems to have been too heavily charged with shadow; and but for the archaeological evidence we should not have known how much genuine human affection lay concealed in those lower social strata whose records can only be studied on their tombs.[99] It was among these classes that Christianity found the readiest acceptance, simply because it gave a supernatural sanction to habits and sentiments already made familiar by the spontaneous tendencies of an unwarlike régime. VII. Before parting with Stoicism we have to say a few words on the metaphysical foundation of the whole system—the theory of Nature considered as a moral guide and support. It has been shown that the ultimate object of this, as of many other ethical theories, both ancient and modern, was to reconcile the instincts of individual self-preservation with virtue, which is the instinct of self-preservation in an entire community. The Stoics identified both impulses by declaring that virtue is the sole good of the individual no less than the supreme interest of the whole; thus involving themselves in an insoluble contradiction. For, from their nominalistic point of view, the good of the whole can be nothing but an aggregate of particular goods, or else a means for their attainment; and in either case the happiness of the individual has to be accounted for apart from his duty. And an analysis of the special virtues and vices would equally have forced them back on the assumption, which they persistently repudiated, that individual existence and pleasure are intrinsically good, and their opposites intrinsically evil. To prove their fundamental paradox—the non-existence of individual as distinguished from social interest—the Stoics employed the analogy of an organised body where the good of the parts unquestionably subserves the good of the whole;[100] and the object of their teleology was to show that the universe and, by implication, the human race, were properly to be viewed in that light. The acknowledged adaptation of life to its environment furnished some plausible arguments in support of their thesis; and the deficiencies were made good by a revival of
