Montaigne, Bayle, and Grotius may be considered the predecessors on the Continent of the French Philosophic movement, but its great impulse came from England. Bacon had much to do with it; Hooker and Hobbes were not without influence; Newton's discoveries directed men's minds towards physical science; but of the metaphysical and political ideas of the century, John Locke was the fountain-head. Some Frenchmen have in modern times disputed his claims. To refute these disputants it is only necessary to turn from their books to those of Voltaire and his contemporaries. The services rendered by France to the human race are so great that her sons need never claim any glory which does not clearly belong to them. All through modern history, Frenchmen have stood in the front rank of civilization. They have stood there side by side with Englishmen, Italians, and Germans. International jealousy should spare the leaders of human thought. They belong to the whole European family of nations. The attempt to set aside Locke, Newton, and Bacon, as guides of the eighteenth century belongs not to that age but to our own. The works of Locke are on the shelves of most considerable libraries; but many men, now that the study of metaphysics is out of fashion, are appalled at the suggestion that they should read an essay in three volumes on the human understanding, evidently considering their own minds less worthy of study than their bodies or their estates. It may be worth while, therefore, to give a short summary of those theories, or discoveries of Locke which most modified French thought in the eighteenth century. The great thinker was born in 1632 and died in 1704. His principal works were published shortly after the English Revolution of 1688, but had been long in preparation; and the "Essay on the Human Understanding" is said to have occupied him not less than twenty years.
