A Ramist tradition took root in Christ's College, Cambridge in the 1570s, when Laurence Chaderton became the leading Ramist, and Gabriel Harvey lectured on the rhetoric of Ramus. Marshall McLuhan's dissertation on Thomas Nashe (via the classical trivium), who was involved in a high-profile literary quarrel with Harvey, was shaped by his interest in aligning Harvey with dialectic and the plain style (logic in the sense of Ramus), and Nashe with the full resources of Elizabethan rhetoric. After Chaderton, there was a succession of important theologians using Ramist logic, including William Perkins, and William Ames (Amesius), who made Ramist dialectic integral to his approach.
