 More published Baxter’s letter and his reply to it, An Answer to a Letter of a Learned Psychopyrist, in his edition of Joseph Glanvill’s Saducismus Triumphatus of 1682. Glanvill, one of More’s most devoted followers, had died before he could produce his response to the anti-witchcraft treatise of John Webster (1611–1682), The Displaying of Supposed Witchcraft (1677), which had attacked Glanvill’s earlier books on the reality of witchcraft (Crocker 2003). But Glanvill’s books on witchcraft were largely intended as contributions to More’s own long standing campaign for proving the existence of a spiritual realm by anecdotal evidence, and so More saw the work through the press. He took the opportunity, however, to add his own most recent attempts to impress his theories on the reading public, including his response to Baxter, an English translation of two chapters from the Enchiridion metaphysicum (chapters 27 and 28) which defined the nature of spirit, and yet more stories of witchcraft and apparitions which More himself had collected.
