were variations from Calvinism's common path which, when augmented by English and French liberalism, by the influence of Quakerism and the frontier, were to give rise to democracy, rationalism, and scientific deism. The Church of England through the seventeenth and eighteenth centuries had "pursued a liberal latitudinarian policy which, as a mode of thought, tended to promote deism by emphasizing rational religion and minimizing revelation."[i-35] It was to be expected that in colonies created by Puritans (or even Quakers), deism would have a less spectacular and extensive success than it appears to have had in the mother country. If militant deism remained an aristocratic cult until the Revolution,[i-36] scientific rationalism (Newtonianism) long before this, from the time of Mather, became a common ally of orthodoxy. If a "religion of nature" may be defined with Tillotson as "obedience to Natural Law, and the performance of such duties as Natural Light, without any express and supernatural revelation, doth dictate to man," then it was in the colonies, prior to the Revolution, more commonly a buttress to revealed religion than an equivalent to it. Lockian sensism and Newtonian science were the chief sources of that brand of colonial rationalism which at first complemented orthodoxy, and finally buried it among lost causes. The Marquis de Chastellux was astounded when he found on a center table in a Massachusetts inn an "Abridgment of Newton's Philosophy"; whereupon he "put some questions" to his host "on physics and geometry," with which he "found him well acquainted."[i-37] Now, even a superficial reading of the eighteenth century discloses countless allusions to Newton, his popularizers, and the implications of his physics and cosmology. As Mr. Brasch suggests, "From the standpoint of the history of science," the extent of the vogue of Newtonianism "is yet very largely unknown history."[i-38]
