This chapter considers whether and in what way Whichcote, More, Cudworth and Smith can be called ‘Platonists’. Was Platonism a part of the story they told about themselves, or that their contemporaries told about them, or is it simply an anachronistic label invented by modern scholarship? I argue that ‘Platonism’ was a live intellectual category in the Cambridge Platonists’ seventeenth-century philosophical and theological context and denoted a particular set of doctrinal positions which were associated with ancient Platonism, such as the primacy of God’s goodness over his will. The chapter also investigates evidence of a surge of interest in ancient and Renaissance Platonism at Cambridge in the latter half of the 1630s, centred at Emmanuel College, which included John Sadler, Peter Sterry and Laurence Sarson and also coincides with Henry More’s discovery of Platonism, and Cudworth’s early Platonic letters to John Stoughton. It is argued that these developments provide important context for the origins of Cambridge Platonism, and illuminate the ways in which Whichcote, More, Cudworth and Smith’s intellectual development was shaped by engagement with Platonic texts and ideas.
