Locke's "internal" questions

Abstract

As Moore does in his proof of the external world, Locke asks the question about the existence of things external to our minds as, in Carnap's sense, an "internal" question. The real reason to be dissatisfied with Locke's causal arguments against skepticism is not that they fail to remove the skeptical alternatives imperiling our knowledge, but in the fact that they sidestep the philosophical skepticism, the characteristically "external" way of posing the philosophical questions about the knowledge of external objects.
