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

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

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.

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.

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.

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.

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.
