Abstract: The aim of this article is twofold: First, it is argued that Tyler Burge’s case for externalism in the philosophy of mind, which is based on Hilary Putnam’s twin-earth thought experiment, fails. Second, it is shown that a convincing argument for externalism can be nonetheless construed by relying on Putnam’s thought experiment.

Keywords: Externalism; twin earth; philosophy of mind; beliefs; Putnam; Burge.
