 The final book in this series, and for the time being the culmination of More’s philosophical ambitions, was the Immortality of the Soul, So farre forth as it is demonstrable from the Knowledge of Nature and the Light of Reason (1659). As is evident from the title, the book marks a return to natural theology, but it also returns to other earlier themes, including the parallel between Cartesian matter theory and the three “vehicles” of the soul, and the reality of spiritual phenomena as revealed in accounts of witchcraft, apparitions, and the like. A major new focus of concern is the philosophy of Thomas Hobbes, whose Leviathan had appeared in 1651. More decries Hobbes for his materialism, his determinism, and his mortalism (emphasising the resurrection of the body on a far distant Day of Judgment, with no interim post mortem punishment, or reward), all of which, of course, are seen by More as incompatible with Christian theism.
