Thus it was that, in the earlier state of Roman society, the most important moral principles--not to add that, from their nature, conscience confirmed and enforced the national law and feeling--really had an authority as strong as any human sanction can give. To violate them involved loss of caste, and a great deal more. The offenders were regarded as traitors against their country; the very mention of their names would be the most deadly insult to those who had the misfortune to be allied to them by blood or marriage. They became a proverb of reproach. So terrible was this punishment that the law which gave to a husband power of life or death over a guilty wife, and the feeling of the nation which not only justified him in executing it, but required it of him, hardly added to its severity. The virtues which tends to success in war were also enforced by the circumstances of Rome. A State contained within the walls of a single city and surrounded by cities, many of which were as powerful as itself, and with each of which it was liable to be at war, depended for its very existence upon the courage, bodily strength, and military training of all its citizens; and if the city was overcome in war, each of them was likely enough to be sold as a slave, or at the very best to be reduced to a position something like that of a serf. No wonder that under such circumstances consuls and dictators were content to hold the plough, and esteemed the success and victory of their country far more important to each of them than their possessions or their life. But when Rome became the head of a widespread empire, the preservation of her early traditions became simply impossible. The contemporaries of Augustus well knew that from war (except, indeed, civil war) they had nothing to fear. The men of a generation earlier were no doubt vexed and provoked by the disastrous defeat of Crassus and the destruction of his army; but their personal comfort, nay, their very pride of superiority to all the world, was no way affected by it. How was it possible that they should really feel like their forefathers, 'When Romans in Rome's quarrel Spared neither land nor gold, Nor son nor wife, nor limb nor life, In the brave days of old?' And, as for the more strictly moral traditions of the early Republicans, they were, from their nature, from the very first, of very limited application. Men who had never learned those glorious truths, 'Which sages would have died to learn, Now taught by cottage dames,'
