A history that should pursue all the subtle threads from end to end might be eminently valuable, but not as a tribute to peace and conciliation. Few discoveries are more irritating than those which expose the pedigree of ideas. Sharp definitions and unsparing analysis would displace the veil beneath which society dissembles its divisions, would make political disputes too violent for compromise and political alliances too precarious for use, and would embitter politics with all the passion of social and religious strife. Sir Erskine May writes for all who take their stand within the broad lines of our constitution. His judgment is averse from extremes. He turns from the discussion of theories, and examines his subject by the daylight of institutions, believing that laws depend much on the condition of society, and little on notions and disputations unsupported by reality. He avows his disbelief even in the influence of Locke, and cares little to inquire how much self-government owes to Independency, or equality to the Quakers; and how democracy was affected by the doctrine that society is founded on contract, that happiness is the end of all government, or labour the only source of wealth; and for this reason, because he always touches ground, and brings to bear, on a vast array of sifted fact, the light of sound sense and tried experience rather than dogmatic precept, all men will read his book with profit, and almost all without offence. Although he does not insist on inculcating a moral, he has stated in his introductory pages the ideas that guide him; and, indeed, the reader who fails to recognise the lesson of the book in every chapter will read in vain. Sir Erskine May is persuaded that it is the tendency of modern progress to elevate the masses of the people, to increase their part in the work and the fruit of civilisation, in comfort and education, in self-respect and independence, in political knowledge and power. Taken for a universal law of history, this would be as visionary as certain generalisations of Montesquieu and Tocqueville; but with the necessary restrictions of time and place, it cannot fairly be disputed. Another conclusion, supported by a far wider induction, is that democracy, like monarchy, is salutary within limits and fatal in excess; that it is the truest friend of freedom or its most unrelenting foe, according as it is mixed or pure; and this ancient and elementary truth of constitutional government is enforced with every variety of impressive and suggestive illustration from the time of the Patriarchs down to the revolution which, in 1874, converted federal Switzerland into an unqualified democracy governed by the direct voice of the entire people.
