Locke, God, and Materialism

Abstract

This chapter investigates Locke’s views about materialism, by looking at the discussion in Essay IV.x. There Locke—after giving a cosmological argument for the existence of God—argues that God could not be material, and that matter alone could never produce thought. In discussing the chapter, I pay particular attention to some comparisons between Locke’s position and those of two other seventeenth-century philosophers, René Descartes and Ralph Cudworth. Making use of those comparisons, I argue for two main claims. The first is that the important argument of Essay IV.x.10 is fundamentally an argument about the causation of perfections. Indeed, Locke gives multiple such arguments in the chapter. My second main claim is that my proposed reading of IV.x is not merely consistent with what Locke says elsewhere about superaddition, but also provides reasons to favor a particular understanding of what superaddition is.
