Critics of Berkeley's divine language argument usually dismiss it for one of two main reasons: (1) it appears to be a mere variation on Descartes's argument for the existence of other minds, or (2) there is too little similarity between human languages and the ‘discourse of nature’. I will first show that the compositional features of language on which Berkeley partially bases his argument include systematicity and productivity – not merely the generativity on which Descartes's is based. I will then show that the analogy between human languages and the discourse of nature is stronger than typically appreciated, even given contemporary understandings of language.
