The supreme function of statesmanship is to provide against preventable evils.
The nation state is the product of that logic. In England … it was worked out to its final conclusion at the Henrician reformation, the event by which the English nation state was fully realised. All exertion of authority, whether the making or the enforcement of law, the taking of collective decisions of an executive (i. e. not legislable) character, the imposition and collection of taxes, the judgment of causes—in short, all duress brought to bear by the society upon the individual—proceeds from one source, and that source an internal and native one. The England of Henry VIII found it impossible that its laws should be made, that its causes should be judged, or that a revenue should be procured from it by an external authority. In other words, there was no such thing as external authority: the expression was a contradiction in terms… There is a name for appealing over the head of the Crown to an authority outside the realm, and that name is treason. The word may be disused, but the thing is not; and the penalties of praemunire, which those guilty of it formerly incurred, were not disproportionate to its seriousness.
I do not believe that the loyalty of those many who over those 270 years, and particularly in this century, worked together and died together as part of the union under the Crown, was to the Crown quite simply, even though they wore the Crown on their uniforms and many of them wore it on their hearts. They were not the mercenaries of a Habsburg empire bound together by personal union and dynastic marriages; they were not the servants of a Hohenzollern empire imposed by military force. It was the Crown of the United Kingdom in parliament which was the centre of loyalty, as it is the essential unifying element of this realm, in the name of which and under the inspiration of which men and women these 270 years have worked and lived and died together.
