M. Guizot, in his elaborate work on the History of Civilization in France, has a few curious pages, on the causes of the decline of civil society in Roman Gaul, and its consequent weakness and ruin. He tells you how the Senators or Clarissimi did not constitute a true aristocracy, able to lead and protect the people, being at the mercy of the Emperor, and nominated and removed at his pleasure. How the Curiales, or wealthy middle class, who were bound by law to fulfil all the municipal offices, and were responsible for the collection of the revenue, found their responsibilities so great, that they by every trick in their power, avoided office. How, as M. Guizot well puts it, the central despotism of Rome stript the Curiales of all they earned, to pay its own functionaries and soldiers; and gave them the power of appointing magistrates, who were only after all the imperial agents of that despotism, for whose sake they robbed their fellow-citizens. How the plebs, comprising the small tradesmen and free artizans, were utterly unable to assert their own opinions or rights. How the slave population, though their condition was much improved, constituted a mere dead weight of helpless brutality. And then he says, that the Roman Empire was dying. Very true: but often as he quotes Salvian, he omits always to tell us what Roman society was dying of. Salvian says, that it was dying of vice. Not of bad laws and class arrangements, but of bad men. M. Guizot belongs to a school which is apt to impute human happiness and prosperity too exclusively to the political constitution under which they may happen to live, irrespectively of the morality of the people themselves. From that, the constitutionalist school, there has been of late a strong reaction, the highest exponent, nay the very coryphaeus of which is Mr. Carlyle. He undervalues, even despises, the influence of laws and constitutions: with him private virtue, from which springs public virtue, is the first and sole cause of national prosperity. My inaugural lecture has told you how deeply I sympathize with his view--taking my stand, as Mr. Carlyle does, on the Hebrew prophets.
