Alexis de Tocqueville (see Vol. XII, p. 117), being commissioned at the age of twenty-six to investigate and report on American prisons, made use of his residence in the United States to gain a thorough insight into the political institutions and social conditions of the great Republic. The results of his observations and reflections were given to the world in 1835, in the two famous volumes _De la Démocratie en Amérique_, which were followed in 1840 by a third and fourth volume under the same title. As an analysis of American political institutions De Tocqueville's work has been superseded by Mr. Bryce's admirable study of the same subject; but as one of the great classics of political philosophy it can never be superseded, and has rarely been rivalled. With all a Frenchman's simplicity and lucidity he traces the manifold results of the democratic spirit; though sometimes an excessive ingenuity, which is also French, leads him to over-speculative conclusions. The work was received with universal applause. _I.--Equality_ The most striking impression which I received during my residence in the United States was that of the equality which reigns there. This equality gives a peculiar character to public opinion and to the laws of that country, and influences the entire structure of society in the most profound degree. Realising that equality, or democracy, was rapidly advancing in the Old World also, I determined to make a thorough study of democratic principles and of their consequences, as they are revealed in the western continent. We have only to review the history of European countries from the days of feudalism, to understand that the development of equality is one of the great designs of Providence; inasmuch as it is universal, inevitable, and lasting, and that every event and every individual contributes to its advancement. It is impossible to believe that a social movement which has proceeded so far as this movement towards equality has done, can be arrested by human efforts, or that the democracy which has bearded kings and barons can be successfully resisted by a wealthy bourgeoisie. We know not whither we are moving; we only know that greater equality is found to-day among Christian populations than has been known before in any age or in any country. I confess to a kind of religious terror in the presence of this irresistible revolution, which has defied every obstacle for the last ten centuries. A new political science is awaited by a world which is wholly new; but the most immediate duties of the statesman are to instruct the democracy, if possible to revive its beliefs, to purify its morals, to enlighten its inexperience by some knowledge of political principles, and to substitute for the blind instincts which sway it, the consciousness of its true interests.
