Then he proceeds to reinterpret in terms of the sensuous natural principle and the ideal rational principle the main doctrines of Lutheran Protestantism. The doctrines of incarnation, original sin, atonement, justification by faith and sanctification, while baseless literally and historically, are symbols of the dual nature of man, as phenomenal and noumenal. And while Kant scourges ecclesiastical religions so far as they have relied upon ceremonies and external authority, upon external rewards and punishments, yet he ascribes transitional value to them in that they have symbolized ultimate moral truths. Although dogmas are but the external vesture of inner truths, yet it may be good for us "to continue to pay reverence to the outward vesture since that has served to bring to general acceptance a doctrine which really rests upon an authority within the soul of man, and which, therefore, needs no miracle to commend it." It is a precarious undertaking to single out some one thing in German philosophy as of typical importance in understanding German national life. Yet I am committed to the venture. My conviction is that we have its root idea in the doctrine of Kant concerning the two realms, one outer, physical and necessary, the other inner, ideal and free. To this we must add that, in spite of their separateness and independence, the primacy always lies with the inner. As compared with this, the philosophy of a Nietzsche, to which so many resort at the present time for explanation of what seems to them otherwise inexplicable, is but a superficial and transitory wave of opinion. Surely the chief mark of distinctively German civilization is its combination of self-conscious idealism with unsurpassed technical efficiency and organization in the varied fields of action. If this is not a realization in fact of what is found in Kant, I am totally at loss for a name by which to characterize it. I do not mean that conscious adherence to the philosophy of Kant has been the cause of the marvelous advances made in Germany in the natural sciences and in the systematic application of the fruits of intelligence to industry, trade, commerce, military affairs, education, civic administration and industrial organization. Such a claim would be absurd. But I do mean, primarily, that Kant detected and formulated the direction in which the German genius was moving, so that his philosophy is of immense prophetic significance; and, secondarily, that his formulation has furnished a banner and a conscious creed which in solid and definite fashion has intensified and deepened the work actually undertaken.
