Abstract
In the fourth book of An Essay Concerning Human Understanding Locke hints that he could explain how God may have created matter exnihilo, but refrains from doing so. Leibniz, when he came upon this passage, pricked up his ears. There ensued a sequence of personal events which are not without charm and piquancy, and a sequence of philosophical events which are of some interest. In this paper we tell the tale.Locke has been discussing the view that the creation of matter out of nothing is so inconceivable — it is so utterly impossible to think of how it might be done — that not even omnipotence could bring off such a feat, and matter must therefore be co-eternal with God.
