"It is hard on Locke to attribute his success so much to opportunity and current. In the history of thought, especially of thought bearing on action, he is, not the greatest certainly, but the largest of all Englishmen, looming tremendously, and filling an immense space. The Lettres sur les Anglais, which put England into continental circulation, deal most with him and Newton, and he is the master of Voltaire and Condillac. As the—unscientific—inventor of the division of power, he is the master of Montesquieu. By his theory of Education and the Social Contract, he is the master of Rousseau, the most powerful political writer that ever lived. By his political economy he is the master of Adam Smith, and, in a sense, of Turgot. He gave to Whiggism whatever general ideas it mixed with the specific national elements, and is the theorist of government by the great families. Lastly, in the Catena of tradition on Toleration, he is very nearly the principal classic."
