The worldliness, through which the Renaissance seems to offer so striking a contrast to the Middle Ages, owed its first origin to the flood of new thoughts, purposes, and views, which transformed the mediaeval conception of nature and man. The spirit is not in itself more hostile to religion than that 'culture' which now holds its place, but which can give us only a feeble notion of the universal ferment which the discovery of a new world of greatness then called forth. This worldliness was not frivolous, but earnest, and was ennobled by art and poetry. It is a lofty necessity of the modern spirit that this attitude, once gained, can never again be lost, that an irresistible impulse forces us to the investigation of men and things, and that we must hold this inquiry to be our proper end and work. How soon and by what paths this search will lead us back to God, and in what ways the religious temper of the individual will be affected by it, are questions which cannot be met by any general answer. The Middle Ages, which spared themselves the trouble of induction and free inquiry, can have no right to impose upon us their dogmatical verdict in a matter of such vast importance.
