Abstract

There is a continuing debate as to whether externalism about mental content is compatible with certain commonly accepted views about the nature of self-knowledge. Both sides to this debate seem to agree that externalism is _not compatible with the traditional view that self-knowledge is acquired by means of observation. In this paper, I argue that externalism is compatible with this traditional view of self-knowledge, and that, in fact, we have good reason to believe that the self-knowledge at issue is acquired by means of observation
