If we should assign to the theosophy of Boehme a position in the development of later philosophy corresponding to the inner content of its principle, it would most properly be placed as a complement to the system of _Spinoza_. If Spinoza taught the flowing back of all the finite into the eternal one, Boehme, on the other hand, shows the procession of the finite from the eternal one, and the inner necessity of this procession, since the being of this one would be rather a not-being without such a self-duplication. Compared with Descartes, Boehme has at least more profoundly apprehended the conception of self-consciousness and the relation of the finite to God. But his historical position in other respects is far too isolated and exceptional, and his mode of statement far too impure, to warrant us in incorporating him anywhere in a series of systems developed continuously and in a genetic connection.
The beginner and founder of modern philosophy is _Descartes_. While he, like the men of the transition epoch just noticed, broke loose entirely from the previous philosophizing, and began his work wholly _de novo_, yet he did not content himself, like Bacon, with merely bringing out a new method, or like Boehme and his contemporaries among the Italians, with affirming philosophical views without a methodical ground. He went further than any of these, and making his standpoint one of universal doubt, he affirms a new, positive, and pregnant philosophical principle, from which he attempted logically to deduce the chief points of his system. The character and novelty of his principle makes him the beginner, and its inner fruitfulness the founder, of modern philosophy.
Rene Descartes (_Renatus Cartesius_) was born in 1596, at La Haye in Torraine. Possessing an independent property, he volunteered as a soldier in his twenty-first year, and served in the wars with the Dutch, the Bavarians, and the Imperialists. After this he travelled a good deal, and then abode a considerable time in Paris. In 1629 he left his native land, and betook himself to Holland, that he might there, undisturbed and unknown, devote himself to philosophy, and elaborate his scientific ideas. He spent twenty years in Holland, enduring much vexatious treatment from fanatical theologians, till in 1649 he accepted an invitation from Queen Christina of Sweden, to visit Stockholm, where he died in the following year.
