contrary, it is law and a central government that are lacking, since
independence exists for external as for internal affairs. The stage
we have reached in the affairs of Europe corresponds to the stage
reached in our internal affairs during the Wars of the Roses, when
turbulent barons frustrated the attempt to make them keep the king's
peace. Thus, although the goal is the same in the two cases, the
steps to be taken in order to achieve it are quite different.

There can be no good international system until the boundaries of
states coincide as nearly as possible with the boundaries of nations.

But it is not easy to say what we mean by a nation. Are the Irish a
nation? Home Rulers say yes, Unionists say no. Are the Ulstermen a
nation? Unionists say yes, Home Rulers say no. In all such cases it
is a party question whether we are to call a group a nation or not. A
German will tell you that the Russian Poles are a nation, but as for
the Prussian Poles, they, of course, are part of Prussia. Professors
can always be hired to prove, by arguments of race or language or
history, that a group about which there is a dispute is, or is not, a
nation, as may be desired by those whom the professors serve. If we
are to avoid all these controversies, we must first of all endeavor to
find some definition of a nation.

A nation is not to be defined by affinities of language or a common
historical origin, though these things often help to produce a nation.
Switzerland is a nation, despite diversities of race, religion, and
language. England and Scotland now form one nation, though they did
not do so at the time of the Civil War. This is shown by Cromwell's
saying, in the height of the conflict, that he would rather be subject
to the domain of the royalists than to that of the Scotch. Great
