 But how is it that this incorporeal substance can “actuate grand proportions of matter”? Here More draws on Neoplatonic emanationism. The Spirit of Nature, he says, actuates matter as it emanates outward in a “sphere of life and activity” (More 1662, Immortality of the Soul, separately paginated, 27). It does so because it is axiomatic that an “Emanative Cause” is “such a cause as merely by Being, no other activity or causality interposed, produces an Effect.” An example of an emanative cause is light from a candle. When a candle is lit it emits light and cannot fail to do so. There must be such a cause in the world, he says, because “something must move itself” (More 1662, Immortality of the Soul, separately paginated, 27).
