Before the rise of the new science of nature there was de- veloped amethod for adjusting the claims of natural reason and moral authority by means of adivision of the field: the doctrine of "the two-fold nature of truth." The realm of the ends and values authoritative for conduct was that of the revealed will of God. The organ for its apprehension was faith. Nature is the object of knowledge and with respect to it the claims of reason are supreme. The two realms are so separate that no conflict can occur. The work of Kant may be regarded as aperpetuation of the method of adjustment by means of partition of territories. He did not of course de- marcate the realm of moral authority on the ground of faith in revelation. He substituted the idea of faith grounded in practical reason. But he continued the older distinction of one realm where the intellect has sway and one in which the re- quirements of will are supreme. He retained also the notion of an isolation of the two fields so complete that there is no possible overlapping and hence no possibility of interference. If the kingdoms of science and of righteousness nowhere touch, there can be no strife between them.
