John Dee's Natural Philosophy: Between Science and Religion

Nicholas Clulee's study makes a specific, checkable historical argument, that John Dee's mathematical work and his later angelic conversations belong to one continuous natural philosophy rather than representing a break between an earlier rational Dee and a later credulous one, a reading built from Dee's own writings across his career rather than from later reputation alone. That documented, career-spanning textual argument is the book's real evidentiary basis. Use it to establish this specific scholarly account of the continuity in Dee's own thought; a claim about the specific content of Dee's angelic system itself, as opposed to its place in his broader philosophy, needs a dedicated primary or reception source such as Asprem's Arguing with Angels.
