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.

Earlier ages fortified themselves behind the sovereign state, behind protectionism and militarism.

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.

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.

Just as characteristic, perhaps, is the intellectual interdependence created through the development of the modern media of communication: post, telegraph, telephone, and popular press.

It is an accepted commonplace in psychology that the spiritual level of people acting as a crowd is far lower than the mean of each individual's intelligence or morality.

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.
