And as on the side of metaphysics they were delivered from the perplexities of speculation, so on the side of ethics they were undisturbed by the perplexities of conscience. Their religion, it is true, had a bearing on their conduct, but a bearing, as we saw, external and mechanical. If they sinned they might be punished directly by physical evil; and from this evil religion might redeem them by the appropriate ceremonies of purgation. But on the other hand they were not conscious of a spiritual relation to God, of sin as an alienation from the divine power and repentance as the means of restoration to grace. The pangs of conscience, the fears and hopes, the triumph and despair of the soul which were the preoccupations of the Puritan, were phenomena unknown to the ancient Greek. He lived and acted undisturbed by scrupulous introspection; and the function of his religion was rather to quiet the conscience by ritual than to excite it by admonition and reproof. From both these points of view, the metaphysical and the ethical, the Greeks were brought by their religion into harmony with the world. Neither the perplexities of the intellect nor the scruples of the conscience intervened to hamper their free activity. Their life was simple, straightforward and clear; and their consciousness directed outwards upon the world, not perplexedly absorbed in the contemplation of itself. On the other hand, this harmony which was the essence of the Greek civilisation, was a temporary compromise, not a final solution. It depended on presumptions of the imagination, not on convictions of the intellect; and as we have seen, it destroyed itself by the process of its own development. The beauty, the singleness, and the freedom which attracts us in the consciousness of the Greek was the result of a poetical view of the world, which did but anticipate in imagination an ideal that was not realised in fact or in thought. It depended on the assumption of anthropomorphic gods, an assumption which could not stand before the criticism of reason, and either broke down into scepticism, or was developed into the conception of a single supreme and spiritual power.
