I cannot even perceive that great men are wanting in those periods of corruption and decay; on the contrary, these periods are often signalized by the appearance of men remarkable for energy of character and stern virtue.[41] If we look at the catalogue of Roman emperors, we find a great number of them as exalted in merit as in rank; we meet with names like those of Trajan, Antoninus Pius, Septimius Severus, Alexander Severus, Jovian; and if we glance beneath the throne, we see a glorious constellation of great doctors of our faith, of martyrs, and apostles of the primitive church; not to consider the number of virtuous pagans. Active, firm, and valorous minds filled the camps and the forums, so that it may reasonably be doubted whether Rome, in the times of Cincinnatus, possessed so great a number of eminent men in every department of human activity. Many other examples might be alleged, to prove that senile and tottering communities, so far from being deficient in men of virtue, talent, and action, possess them probably in greater number than young and rising states; and that their general standard of morals is often higher. Public morality, indeed, varies greatly at different periods of a nation's history. The history of the French nation, better than any other, illustrates this fact. Few will deny that the Gallo-Romans of the fifth and sixth centuries, though a subject race, were greatly superior in point of morals to their heroic conquerors.[42] Individually taken, they were often not inferior to the latter in courage and military virtue.[43] The intermixture of the two races, during the eighth, ninth, and tenth centuries, reduced the standard of morals among the whole nation to a disgraceful level. In the three succeeding centuries, the picture brightens again. Yet, this period of comparative light was succeeded by the dark scenes of the fourteenth and fifteenth centuries, when tyranny and debauchery ran riot over the land, and infected all classes of society, not excepting the clergy; when the nobles robbed their vassals, and the commonalty sold their country to a foreign foe. This period, so distinguished for the total absence of patriotism, and every honest sentiment, was emphatically one of decay; the state was shaken to its very foundation, and seemed ready to bury under its ruins so much shame and dishonor. But the crisis passed; foreign and intestine foes were vanquished; the machinery of government reconstructed on a firmer basis; the state of society improved. Notwithstanding its bloody follies, the sixteenth century dishonors less the annals of the nation than its predecessors, and it formed the transition period to the age of those pure and ever-brilliant lights, Fenelon, Bossuet, Montausier, and others. This period, again, was succeeded by the vices of the regency, and the horrors of the Revolution. Since that time, we have witnessed almost incredible fluctuations of public morality every decade of years.
