To this corresponds a profound difference in their systems, which is by no means adequately characterized by saying that Hobbes brings into the foreground the mathematical element neglected by his predecessor, and turns his attention chiefly to politics. The dependence of Hobbes on Bacon is, in spite of their personal acquaintance, not so great as formerly was universally assumed. His guiding stars are rather the great mathematicians of the Continent, Kepler and Galileo, while Cartesian influences also are not to be denied. He finds his mission in the construction of a strictly mechanical view of the world. Mechanism applied to the world gives materialism; applied to knowledge, sensationalism of a mathematical type; applied to the will, determinism; to morality and the state, ethical and political naturalism. Nevertheless, the empirical tendency of his nation has a certain power over him; he holds fast to the position that all ideas ultimately spring from experience. With his energetic but short-breathed thinking, he did not succeed in fusing the rationalistic elements received from foreign sources with these native tendencies, so as to produce a unified system. As Grimm has correctly shown (Zur Geschichte des Erkenntnissproblems), there is an unreconciled contradiction between the dependence of thought on experience, which he does not give up, and the universal validity of the truths derived from pure reason, which he asserts on the basis of the mathematico-philosophical doctrines of the Continent. A similar unmediated dualism will meet us in Locke also.
Thomas Hobbes (1588-1679) was repelled while a student at Oxford by Scholastic methods in thought, with which he agreed only in their nominalistic results (there are no universals except names). During repeated sojourns in Paris, where he made the acquaintance of Gassendi, Mersenne, and Descartes, he devoted himself to the study of mathematics, and was greatly influenced by the doctrines of Galileo; while the disorders of the English revolution led him to embrace an absolutist theory of the state. His chief works were his politics, under the title Leviathan, 1651, and his Elementa Philosophiae, in three parts (De Corpore, De Homine, De Cive), of
