Identifier: Coll-33/Quarto A [45]
Scope and Contents A short critique of William Whiston's A New Theory of the Earth, from its Original to the Consummation of all Things, (1696) , intended to damn Cartesian astronomy and advance corollaries to Newtonian thought instead. He affirmed the truth of the flood narrative in Genesis, ascribing the deluge to the impact of a comet. Whiston had been converted to Newtonianism by a paper of David Gregory. At the foot of this document is an unrelated note, dated 6 Sept. 1708, to the...
