Chapter 1

The appeal to history. Previous great schisms in Europe which have been surmounted give hope for the present. The Reformation. The Napoleonic Wars.

The two points of view, (1) Man's nature itself tending to unity through conflict. (2) The stages in the process developed in history.

In pre-history conflict and diversity are predominant, though the necessities of life prescribe certain uniformities. Consolidation comes in favoured physical conditions, especially great river-basins like the Nile and the Euphrates.

The possibility of a world-unity first consciously envisaged in the Greco-Roman world. Greece gives unity in thought, Rome in practice. Order with a solid intellectual foundation established with the Roman Empire. In the mediaeval world a unity mainly spiritual is reached in the same framework. The position of Germany in this development. The break-up of the fourteenth and fifteenth century. The enlargement of the known world and the growth of wealth and knowledge. This crisis still continues and has been recently accentuated by the birth-throes of nationalities. The supreme problem for international unity is now the reconciliation of national units with the interests of the whole. Underneath the superficial turmoil the great unifying forces of science and of common sentiments continue to grow and will ultimately prevail.
