One of the most influential and significant developments in the philosophy of language over the last thirty years has been the rise of externalist conceptions of content. This essay aims to explore the implications of a form of externalism, largely derived from the work of Donald Davidson, for thinking about history, and in so doing to suggest one way in which contemporary philosophy of language may engage with contemporary philosophy of history. Much of the discussion focuses on the elaboration of the externalism that is at issue, along with the holistic approach to content with which it is connected. It will be argued that such holistic externalism is itself thoroughly in keeping with the very character of historical inquiry itself, and can be seen to provide an underpinning to certain contemporary developments in historical thinking.
