intellect, knowing the world and its ways. “The book has surpassed my hope,” said Henry IV. The style is as supple, the fancy as rich, as Montaigne’s; but scepticism has given place to Christianism; St. Francis de Sales does not doubt, he believes; ingenious and moderate withal, he escapes out of the controversies of the violent and the incertitudes of the sceptics. The step is firm, the march is onward towards the seventeenth century, towards the reign of order, rule, and method. The vigorous language and the beautiful arrangement in the style of the magistrates had already prepared the way for its advent. Descartes was the first master of it and its great exponent. [Illustration: Descartes at Amsterdam----316] Never was any mind more independent in voluntary submission to an inexorable logic. Rene Descartes, who was born at La Haye, near Tours, in 1596, and died at Stockholm in 1650, escaped the influence of Richelieu by the isolation to which he condemned himself, as well as by the proud and somewhat uncouth independence of his character. Engaging as a volunteer, at one and twenty, in the Dutch army, he marched over Germany in the service of several princes, returned to France, where he sold his property, travelled through the whole of Italy, and ended, in 1629, by settling himself in Holland, seeking everywhere solitude and room for his thoughts. “In this great city of Amsterdam, where I am now,” he wrote to Balzac, “and where there is not a soul, except myself, that does not follow some commercial pursuit, everybody is so attentive to his gains, that I might live there all my life without being noticed by anybody.

I confess that if the notion of the earth’s motion is false, all the foundations of my philosophy are too, since it is clearly demonstrated by them. It is so connected with all parts of my treatise that I could not detach it without rendering the remainder
