Abstract

“Intentionality,” as introduced to modern philosophy by Brentano, denotes the property that distinguishes the mental from all other things. As such, intentionality has been related to purposiveness. I suggest, however, that there are many kinds of purposes that are not mental nor derived from anything mental, such as the purpose of one’s stomach to digest food or the purpose of one’s protective eye blink reflex to keep out the sand. These purposes help us to understand intentionality in a naturalistic way. The naturalist challenge here is to show, first, that natural purposiveness can explain the intentionality of explicitly represented purposes, hence that it is associated with “aboutness” (as in Brentano’s usage). Second, it needs to show how the same kind of analysis can also be used to naturalize intentionality in cases where facts are represented rather than purposes or ends.
