More than once, a society has been seen to give way before the wind which is let loose upon mankind; history is full of the shipwrecks of nations and empires; manners, customs, laws, religions⁠—and some fine day that unknown force, the hurricane, passes by and bears them all away. The civilizations of India, of Chaldea, of Persia, of Syria, of Egypt, have disappeared one after the other. Why? We know not. What are the causes of these disasters? We do not know. Could these societies have been saved? Was it their fault? Did they persist in the fatal vice which destroyed them? What is the amount of suicide in these terrible deaths of a nation and a race? Questions to which there exists no reply. Darkness enwraps condemned civilizations. They sprung a leak, then they sank. We have nothing more to say; and it is with a sort of terror that we look on, at the bottom of that sea which is called the past, behind those colossal waves, at the shipwreck of those immense vessels, Babylon, Nineveh, Tarsus, Thebes, Rome, beneath the fearful gusts which emerge from all the mouths of the shadows. But shadows are there, and light is here. We are not acquainted with the maladies of these ancient civilizations, we do not know the infirmities of our own.
