Newton thought highly of it and contributed his ‘lunar theory’—which had long served as a guide for practical astronomers in determining the Moon’s motions—for inclusion in it (p. 332). The discussion in the preface, in which the doctrine of gravitation was vindicated on the grounds of its antiquity, likewise originated with Newton.” (DNB) – Second expanded edition. – 38.
