John Locke's comments on experimental natural philosophy can plausibly be seen as a part of the physico-theological project of certain Christian virtuosi of the Royal Society to show that the workings of nature reveal the existence of a providential God. As I make clear, Locke thinks that God providentially designs us with limited epistemic capacities in order to check our pride and to motivate us to seek perfection in God. Locke maintains that a true science of nature is possible, but (...) he is pessimistic about the prospects of realizing such a science, given our epistemic limitations. I argue that this seeming tension can be resolved by appreciating that the horizon for obtaining this science is eschatological. In other words, Locke thinks that we will have a true science of nature in a state of perfection, as God transforms the probable knowledge we have of bodies into certain and comprehensive knowledge.
