This pedantry would destroy itself: by the application of the same principles it could be proved that a General Election was necessary once a month, or once a week, or once a day. But the real objection is that which these _a priori_ Reformers constantly overlooked, the fact that a Constitution is after all only {108} a machine contrived for certain practical ends of government, that it must be arranged upon a basis of convenience, and that infinitely greater hardship could be inflicted upon the country by interrupting trade for one month in every twelve and spending a million pounds in unproductive ways, than by forcing a small portion of the population to abstain from voting even until it was as much as twenty-eight years old. These doctrines being based upon pure logic, and not upon practical convenience, were naturally made applicable to all peoples without distinction. "All being pure and genuine," said Cartwright, "the result will be, a strict unity of form universally applicable; and exhibiting its subject, political liberty, as evidently a common right and inheritance of every people or nation; for to talk of English liberty, and French or Spanish or Italian liberty, as different in nature is contrary to reason."[120] It is easy to understand why men like Fox and Grey, accustomed to grapple with the affairs of men who were swayed by prejudice, tradition, interest, by everything but reason, were contemptuous of political theories of this sort. No one who has been engaged in active politics can fail to understand that men are infinitely variable, and that what suits one race will not suit another. There was really only one problem to consider. Given a society with a known history, composed of human beings of a known character, and distributed among known conditions, what form of government was best suited to their case? Origin, character, social and economic distribution, and past history, are all different in different peoples, and political institutions will inevitably differ also. The Radicals were far enough away from real life. But with all their incapacity for politics, they performed the great service of preaching the political importance of individuality.
