Why did a thousand years invent nothing better than Sibylline books, Orphic poems, Byzantine imitations of classical histories, Christian reproductions of Greek plays, novels like the silly and obscene romances of Longus and Heliodorus, innumerable forged epistles, a great many epigrams, biographies of the meanest and most meagre description, a sham philosophy which was the bastard progeny of the union between Hellas and the East? Only in Plutarch, in Lucian, in Longinus, in the Roman emperors Marcus Aurelius and Julian, in some of the Christian fathers are there any traces of good sense or originality, or any power of arousing the interest of later ages. And when new books ceased to be written, why did hosts of grammarians and interpreters flock in, who never attain to any sound notion either of grammar or interpretation? Why did the physical sciences never arrive at any true knowledge or make any real progress? Why did poetry droop and languish? Why did history degenerate into fable? Why did words lose their power of expression? Why were ages of external greatness and magnificence attended by all the signs of decay in the human mind which are possible?
To these questions many answers may be given, which if not the true causes, are at least to be reckoned among the symptoms of the decline. There is the want of method in physical science, the want of criticism in history, the want of simplicity or delicacy in poetry, the want of political freedom, which is the true atmosphere of public speaking, in oratory.
