ONE:Meanwhile a new and powerful agency was about to interpose with decisive effect in the doubtful struggle. This was the study of mathematics. Revived by the Arabians and never wholly neglected during the Middle Ages, it had profited by the general movement of the Renaissance, and was finally applied to the cosmical problem by Galileo. In this connexion, two points of profound philosophical interest must be noted. The first is that, even in its fall, the Aristotelian influence survived, to some extent, both for good and for evil. To Aristotle belongs the merit of having been the first to base astronomy on physics. He maintains the earths immobility on experimental no less than on speculative grounds. A stone thrown straight up in the air returns to its starting-point instead of falling to the west of it; and the absence of stellar385 parallax seems to show that there is no change in our position relatively to the heavenly bodies. After satisfying himself, on empirical considerations, that the popular astronomy is true, he proceeds to show that it must be true, by considerations on the nature of matter and motion, which, although mistaken, are conceived in a genuinely scientific spirit. Now Galileo saw that, to establish the Copernican system, he must first grapple with the Peripatetic physics, and replace it by a new dynamical theory. This, which he could hardly have effected by the ordinary mathematical methods, he did by borrowing the analytical method of Atomism and applying it to the measurement of motion. The law of falling bodies was ascertained by resolving their descent into a series of moments, and determining its rate of velocity at successive intervals; and curvilinear motions were similarly resolved into the combination of an impulsive with an accelerating force, a method diametrically opposed to that of Bacon, who would not even accept the rough analysis of the apparent celestial motions proposed by Greek astronomers.
TWO:In the department of philosophy flourished also Bishop Berkeley (b. 1684; d. 1753), author of "The Principles of Human Knowledge," whostartled the world with the theory that matter has no existence in the universe, but is merely a fixed idea of the mind; Dr. Mandeville, a Dutchman by birth, who settled in London, and published various medical and metaphysical works of a freethinking character; Hutchinson, an opponent of Dr. Woodward in natural history, and Newton in natural philosophy; and David Hartley, author of "Observations on Man." Bishop Butler, Warburton, Hoadley, Middleton, author of "A Free Inquiry into the Miraculous Powers of the Church," and Secker, Archbishop of Canterbury, were the leading theologians in the Church; but Dissent could also boast of its men of light and leading in Dr. Isaac Watts, author of a system of Logic and of the popular Hymns; Calamy, the opponent of Hoadley; Doddridge, and others.
ONE:A few minutes before seven they all came back into the sitting room. The men wore black coats, by way of compromise, and Mrs. Kirby and the children were in white.
TWO:It was plain, even to Felipa, how thoroughly he enjoyed being with one who could talk of the past and of the present, from his own point of view. His Coventry had been almost complete since the day that the entire army, impersonated in Crook, had turned disapproving eyes upon him once, and had then looked away from him for good and all. It had been too bitter[Pg 310] a humiliation for him ever to subject himself to the chance of it again.And thats why you brought us hereto help you watch? Sandy asked.
