I examine three arguments that purport to show that connectionist, associationist architectures cannot achieve key features of human thought. Hume anticipated each of these three arguments and provided a unified strategy for responding to each, the “externalist gambit.” On this account, external natural language provides the necessary structure for associationist systems to achieve those features of thought that their opponents take them to lack. The externalist gambit provides a promising avenue for today’s defenders of connectionism about the human mind.
