Greek philosophy was one of the distinctive features of ancient civilization long after the Greeks had ceased to speculate on the laws of mind or the nature of the soul, on the existence of God or future rewards and punishments. Although it was purely Grecian in its origin and development, it became one of the grand ornaments of the Roman schools. The Romans did not originate medicine, but Galen was one of its greatest lights; they did not invent the hexameter verse, but Virgil sang to its measure; they did not create Ionic capitals, but their cities were ornamented with marble temples on the same principles as those which called out the admiration of Pericles. So, if they did not originate philosophy, and generally had but little taste for it, still its truths were systematized and explained by Cicero, and formed no small accession to the treasures with which cultivated intellects sought everywhere to be enriched. It formed an essential part of the intellectual wealth of the civilized world, when civilization could not prevent the world from falling into decay and ruin. And as it was the noblest triumph which the human mind, under Pagan influences, ever achieved, so it was followed by the most degrading imbecility into which man, in civilized countries, was ever allowed to fall. Philosophy, like art, like literature, like science, arose, shone, grew dim, and passed away, leaving the world in night. Why was so bright a glory followed by so dismal a shame? What a comment is this on the greatness and littleness of man!
