The long ages of infancy and childhood, through which the human race had to pass, have receded into the background. Humanity is now experiencing the commotions invariably associated with the most turbulent stage of its evolution, the stage of adolescence, when the impetuosity of youth and its vehemence reach their climax, and must gradually be superseded by the calmness, the wisdom, and the maturity that characterize the stage of manhood. Then will the human race reach that stature of ripeness which will enable it to acquire all the powers and capacities upon which its ultimate development must depend. ... Unification of the whole of mankind is the hall mark of the stage which human society is now approaching. Unity of family, of tribe, of city-state, and nation have been successively attempted and fully established. World unity is the goal towards which a harassed humanity is striving. Nation-building has come to an end. The anarchy inherent in state sovereignty is moving towards a climax. A world, growing to maturity, must abandon this fetish, recognize the oneness and wholeness of human relationships, and establish once for all the machinery that can best incarnate this fundamental principle of its life. ...

A world executive, backed by an international Force, will carry out the decisions arrived at, and apply the laws enacted by, this world legislature, and will safeguard the organic unity of the whole commonwealth. A world tribunal will adjudicate and deliver its compulsory and final verdict in all and any disputes that may arise between the various elements constituting this universal system. A mechanism of world inter-communication will be devised, embracing the whole planet, freed from national hindrances and restrictions, and functioning with marvellous swiftness and perfect regularity. A world metropolis will act as the nerve centre of a world civilization, the focus towards which the unifying forces of life will converge and from which its energizing influences will radiate. A world language will either be invented or chosen from among the existing languages and will be taught in the schools of all the federated nations as an auxiliary to their mother tongue.
