Thomas Tenison was a prominent English churchman who became archbishop of Canterbury in 1695. He administered to both William and Mary at their deathbeds, though he was less popular with Queen Anne. He was a founder of the Society for the Propagation of the Gospel. G.A.J. Rogers discusses this work at length in the Dictionary of Seventeenth-Century British Philosophers. He notes that "Tenison recognized the intellectual power in Hobbes's philosophy, and this made him a much more worthy critic than many who took up the sword against Hobbes." The book is written in the form of a dialogue between 'Hobbes' and 'a Student,' who represents Tenison. The Student attacks Hobbes' conception of a deity and states that 'Hobbes' fails to distinguish between having an idea of God and having an image of God, noting that we cannot have an image of a non-material God, but we can have an idea of one. This leads to an examination of the nature of space and the coherence of the doctrine of the Trinity, the possibility of an infinite cause, the possibility of the universe having a beginning, and the coherence of immaterial substances. "Tenison provides powerful argument for his non-materialist position and challenges Hobbes's claims in forceful ways. He does so without seriously distorting Hobbes's own position, which gives the whole work a strength often lacking in anti-Hobbist literature of the period. Although it is Tenison's only truly philosophical work it provides considerable evidence of his intellectual sophistication, and shows that debate with Hobbes in the seventeenth century could be philosophically fruitful" (ibid, p. 809). ESTC states that several copies are found in British libraries, although it is still quite scarce in American libraries. Wing (CD-ROM, 1996).
