But teleological considerations can lead no further than to a belief and a hope. They do not give certainty.
All species capable of grasping this fact manage better in the struggle for existence than those which rely upon their own strength alone: the wolf, which hunts in a pack, has a greater chance of survival than the lion, which hunts alone.
A pacifist will often - at least nowadays - be an internationalist and vice versa. But history shows us that a pacifist need not think internationally.
Hand in hand with nationalist economic isolationism, militarism struggles to maintain the sovereign state against the forward march of internationalism.
The idea of eternity lives in all of us. We thirst to live in a belief which raises our small personality to a higher coherence - a coherence which is human and yet superhuman, absolute and yet steadily growing and developing, ideal and yet real.
Internationalism is a community theory of society which is founded on economic, spiritual, and biological facts. It maintains that respect for a healthy development of human society and of world civilization requires that mankind be organized internationally.
Within each such social group, a feeling of solidarity prevails, a compelling need to work together and a joy in doing so that represent a high moral value.
Upon the union of the male germ cell with the female egg cell, a new cell is created which almost immediately splits into two parts. One of these grows rapidly, creating the human body of the individual with all its organs, and dies only with the individual.
Today we stand on a bridge leading from the territorial state to the world community. Politically, we are still governed by the concept of the territorial state; economically and technically, we live under the auspices of worldwide communications and worldwide markets.
The theoretically unrestricted right to develop power, to wage war against other states, is antisocial and is doubly dangerous, because the state as a mass entity represents a low moral and intellectual level.
The territorial state is such an ancient form of society - here in Europe it dates back thousands of years - that it is now protected by the sanctity of age and the glory of tradition. A strong religious feeling mingles with the respect and the devotion to the fatherland.
The sovereign state has in our times become a lethal danger to human civilization because technical developments enable it to employ an infinite number and variety of means of destruction.
Moreover, if the territorial state is to continue as the last word in the development of society, then war is inevitable.
The main concept is that of an international solidarity expressed in practice through worldwide division of labor: free trade is the principal point in the program of internationalism.
Modern techniques have torn down state frontiers, both economical and intellectual. The growth of means of transport has created a world market and an opportunity for division of labor embracing all the developed and most of the undeveloped states.
