the merely sentimental diagnosis which explains wars or other national blunders by outbursts of patriotic animosity or errors of statecraft. Doubtless at every outbreak of war not only the man in the street but the man at the helm is often duped by the cunning with which aggressive motives and greedy purposes dress themselves in defensive clothing. There is, it may be safely asserted, no war within memory, however nakedly aggressive it may seem to the dispassionate historian, which has not been presented to the people who were called upon to fight as a necessary defensive policy, in which the honour, perhaps the very existence, of the State was involved.
The disastrous folly of these wars, the material and moral damage inflicted even on the victor, appear so plain to the disinterested spectator that he is apt to despair of any State attaining years of discretion, and inclines to regard these natural cataclysms as implying some ultimate irrationalism in politics. But careful analysis of the existing relations between business and politics shows that the aggressive Imperialism which we seek to understand is not in the main the product of blind passions of races or of the mixed folly and ambition of politicians. It is far more rational than at first sight appears. Irrational from the standpoint of the whole nation, it is rational enough from the standpoint of certain classes in the nation. A completely socialist State which kept good books and presented regular balance-sheets of expenditure and assets would soon discard Imperialism; an intelligent laissez-faire democracy which gave duly proportionate weight in its policy to all economic interests alike would do the same. But a State in which certain well-organised business interests are able to outweigh the weak, diffused interest of the community is bound to pursue a policy which accords with the pressure of the former interests.
In order to explain Imperialism on this hypothesis we have to answer two questions. Do we find in Great Britain to-day any well-organised group of special commercial and social interests which stand to gain by
