November 10

It [the principle of the Oneness of Mankind] implies an organic change in the structure of present-day society, a change such as the world has not yet experienced. It constitutes a challenge, at once bold and universal, to outworn shibboleths of national creeds -- creeds that have had their day and which must, in the ordinary course of events as shaped and controlled by Providence, give way to a new gospel, fundamentally different from, and infinitely superior to, what the world has already conceived. It calls for no less that the reconstruction and the demilitarization of the whole civilized world -- a world organically unified in all the essential aspects of its life, its political machinery, its spiritual aspiration, its trade and finance, its script and language, and yet infinite in the diversity of the national characteristics of its federated units. .
