Under the influence of the English thinker the scientific period was ushered in. The study of social science is beginning; men profess a materialism or a positivism hostile to the older ontological ideas; they believe in science even more than in the sciences, { 277} in the rational explanation of all mysteries, in the supremacy of mathematics and physics. Various influences are at work, and the confused result thereof favours the triumph of positivism. The political and social theories of Dr. Gustave Le Bon, the impetuous writings of Max Nordau, the criminology of Lombroso and Ferri, the formulæ of Taine, the biology and sociology of Letourneau, are studied and commented upon in the universities, the parliaments, and the schools of South America. Eloquence is repudiated as contrary to scientific precision, and romantic faith is disdained by the positivist. A party which has ruled over the evolution of Mexico for the last thirty years has named itself the "Scientific Party."
The significance of these doctrines rapidly acquired an excessive importance; in place of lucid methods and clear ideas we find the teaching of the professors full of the narrowness of dogma. Positivism implants a limited and vulgar rationalism, a new metaphysic which accords an absolute truth to the formulæ of science; which exalts egoism and practical interests, and the frantic pursuit of wealth in daily life. The tendency of the American mind being undue simplification, this philosophy has not been a discipline of knowledge and action, but has limited the effort of man to the conquest of the useful. The positivists organise plutocratic tyrannies in certain American nations.
Without reigning in the schools as Spencer has done, a French philosopher, M. Fouillée, has greatly influenced law, politics, and education. In spite of the reign of positivism his flexible doctrine has attracted many Americans, and his works, such as the _Idée du Droit_ and the _Histoire de la Philosophie_, are coming into use as text-books in some universities. The theory of unavoidable ideas is well known; and thinkers and philosophers have been { 278} inspired by this "philosophy of hope." By its noble idealism, by its admirable wealth, its serene rationalism, and its essentially Latin character, the harmonious system of M. Fouillée has won considerable popularity among the youth of America.
