Technology is a useful servant but a dangerous master.

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.

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

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.

Only recently, during the nineteenth century, and then only in Europe, do we meet forms of the state which have been created by a deliberate national feeling.

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.

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.
