Two centuries ago the Abbé de Saint-Pierre set forth his scheme for a federation of the States of Europe, which meant, at that time, a federation of all the civilised states of the world. It was the age of great ideas, scattered abroad to germinate in more practical ages to come.
The amiable Abbé enjoyed all the credit of his large and philanthropic conceptions. But no one dreamed of realizing them, and the forces which alone could realize them had not yet appeared above the horizon.
13In this matter, at all events, the world has progressed, and a federation of the States of the world is no longer the mere conception of a philosophic dreamer. The first step will be taken when two of the leading countries of the world—and it would be most reasonable for the states having the closest community of origin and language to take the initiative—resolve to submit all their differences without reserve to arbitration. As soon as a third power of magnitude joined this federation the nucleus would be constituted of a world state. Such a state would be able to impose peace on even the most recalcitrant outside states, for it would furnish that "visible power to keep them in awe," which Hobbes rightly declared to be indispensable; it could even, in the last resort, if necessary, enforce peace by war. Thus there might still be war in the world. But there would be no wars that were not Holy Wars. There are other methods than war of enforcing peace, and these such a federation of great states would be easily able to bring to bear on even the most warlike of states, but the necessity of a mighty armed international force would remain for a long time to come.
