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. Nationalities should form the constitutive links in a great world alliance, and must be guaranteed an independent life in the realm of the spiritual and for locally delimited tasks, while economic and political objectives must be guided internationally in a spirit of peaceful cooperation for the promotion of mankind's common interests.

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.

But teleological considerations can lead no further than to a belief and a hope. They do not give certainty.

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.

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

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

Internationalism on the other hand admits that spiritual achievements have their roots deep in national life; from this national consciousness art and literature derive their character and strength and on it even many of the humanistic sciences are firmly based.
