This article discusses Isaac Newton’s relations with two older colleagues at the University of Cambridge, Ralph Cudworth and Henry More, two of the so-called Cambridge Platonists,. It shows that there are biographical links between them, especially between More and Newton. Despite differences in theological outlook (e.g. on the Trinity), they shared intellectual interests and scholarly approach. All three were critical of Descartes, and More, like Newton, posited infinite space. In addition, there were parallels in their investigations of biblical prophecy—thanks to their debt to the Cambridge Bible scholar Joseph Mede. Newton drew on Cudworth and, like More, examined the texts of the Kabbala denudata. It is argued here that, although Newton differed from them in his conclusions, More and Cudworth were a significant part of Newton’s intellectual background.
