Abstract

How are the contents of our beliefs, our intentions, and other attitudes individuated? Just what makes our contents what they are? Content externalism, as Hilary Putnam, Tyler Burge, and others have argued, is the position that our contents depend in a constitutive manner on items in the external world, that they can be individuated by our causal interaction with the items they are about. Content internalism, by contrast, is the position that our contents depend primarily on the properties of our bodies, such as our brains. Internalists, moreover, typically hold that our contents are narrow, insofar as they locally supervene on the properties of our bodies or brains. In this article surveys the arguments and problems for these contrasting positions.
