But it is not sufficient for a moral system to form a bulwark against vice, it must also be capable of admitting those extensions and refinements of moral sympathies which advancing civilisation produces, and the inflexibility of its antagonism to evil by no means implies its capacity of enlarging its conceptions of good. During the period which elapsed between the importation of Stoical tenets into Rome and the ascendancy of Christianity, an extremely important transformation of moral ideas had been effected by political changes, and it became a question how far the new elements could coalesce with the Stoical ideal, and how far they tended to replace it by an essentially different type. These changes were twofold, but were very closely connected. They consisted of the increasing prominence of the benevolent or amiable, as distinguished from the heroic qualities, and of the enlargement of moral sympathies, which having at first comprised only a class or a nation, came at last, by the destruction of many artificial barriers, to include all classes and all nations. The causes of these changes—which were the most important antecedents of the triumph of Christianity—are very complicated and numerous, but it will, I think, be possible to give in a few pages a sufficiently clear outline of the movement. It originated in the Roman Empire at the time when the union of the Greek and Latin civilisations was effected by the conquest of Greece. The general humanity of the Greeks had always been incomparably greater than that of the Romans. The refining influence of their art and literature, their ignorance of gladiatorial games, and their comparative freedom from the spirit of conquest, had separated them widely from their semi-barbarous conquerors, and had given a peculiar softness and tenderness to their ideal characters. Pericles, who, when the friends who had gathered round his death-bed, imagining him to be insensible, were recounting his splendid deeds, told them that they had forgotten his best title to fame—that “no Athenian had ever worn mourning on his account;” Aristides, praying the gods that those who had banished him might never be compelled by danger or suffering to recall him; Phocion, when unjustly condemned, exhorting his son never to avenge his death, all represent a type of character of a milder kind than that which Roman influences produced. The plays of Euripides had been to the ancient world the first great revelation of the supreme beauty of the gentler virtues. Among the many forms of worship that flourished at Athens, there was an altar which stood alone, conspicuous and honoured beyond all others. The suppliants thronged around it, but no image of a god, no symbol of dogma was there. It was dedicated to Pity, and was venerated through all the ancient world as the first great assertion among mankind of the supremo sanctity of Mercy.(347)
