 It is perhaps worth noting also that John Finch, More’s former student and Anne’s half-brother, also moved away from More’s way of thinking at this time. During his time in Turkey as a diplomat (1674–1681), Finch wrote a large manuscript Treatise of natural philosophy which remains unpublished. Finch’s philosophy is materialist and based on an empiricist epistemology, and is highly critical of many of More’s views. Rejecting More’s dualism, Finch takes an almost Hobbesian line, but couples it with fideism in religion: we cannot prove the existence of God or immaterial substances by the use of reason and so must trust in the Gospels (Crocker 2003).
