Concord, solidarity, and mutual help are the most important means of enabling animal species to survive.

Hand in hand with nationalist economic isolationism, militarism struggles to maintain the sovereign state against the forward march of internationalism.

It is against this concept of the sovereign state, a state isolated by protectionism and militarism, that internationalism must now engage in decisive battle.

Propaganda must appeal to mankind's better judgment and to the necessary belief in a better future. For this belief, the valley of the shadow of death is but a war station on the road to the blessed summit.

The free trade movement in the middle of the last century represents the first conscious recognition of these new circumstances and of the necessity to adapt to them.

In particular, the efforts to reestablish peace after the World War have been directed toward the formation of states and the regulation of their frontiers according to a consciously national program.

Like all social theories, internationalism must seek its basis in the economic and technical fields; here are to be found the most profound and the most decisive factors in the development of society.

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.

A pacifist will often -- at least nowadays -- be an internationalist and vice versa. But history shows us that a pacifist need not think internationally.

No state is free from militarism, which is inherent in the very concept of the sovereign state. There are merely differences of degree in the militarism of states.

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.

For the state by its nature claims sovereignty, the right to an unlimited development of power, determined only by self-interest. It is by nature anarchistic.

Militarism is basically a way of thinking, a certain interpretation of the function of the state; this manner of thinking is, moreover, revealed by its outer forms: by armaments and state organization.

It is characteristic that this should take place just when it is becoming more and more clear to all who think about the matter, that technically and economically we have left the territorial state behind us.

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.

Every time economic and technical development takes a step forward, forces emerge which attempt to create political forms for what, on the economic-technical plane, has already more or less become reality.

On the contrary. Internationalism also recognizes, by its very name, that nations do exist. It simply limits their scope more than one-sided nationalism does.

Internationalism is a social and political theory, a certain concept of how human society ought to be organized, and in particular a concept of how the nations ought to organize their mutual relations.

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.
