Leibniz on Spontaneity, The Eduction of Substantial Forms, and Creaturely Interaction

Abstract

Leibniz argued that (i) substantial forms only begin to exist via Divine creation; (ii) created substances cannot transeuntly cause accidents in distinct substances; and yet (iii) created substances immanently produce their accidents. Some of Leibniz’s support for (i) came from his endorsement of a widely-made argument against the eduction of substantial forms. However, in defense of eduction, Suárez argued that if creatures cannot produce substantial forms, they also cannot produce accidents, threatening the consistency of (i) and (iii). In this paper, I argue that Leibniz successfully defends the consistency of (i) and (iii) against Suárez’s argument, but at the expense of the consistency of (ii) and (iii).
