Optimality vs. Intent: Limitations of Dennett's Artifact Hermeneutics.

Dennett has argued that when people interpret artifacts and other designed objects (such as biological items) they rely on optimality considerations, rather than on designer's intentions. On his view, we infer an item's function by finding out what it is best at; and such functional attribution is more reliable than when we depend on the intention it was developed with. This paper examines research in cognitive psychology and archaeology, and argues that Dennett's account is implausible. We conclude that, quite in contrast to Dennett, intentional considerations play a crucial role in artifact hermeneutics, and even stronger, are necessary for the sake of simplicity and precision. Finally, we question Dennett's contention that the interpretation of artifacts is the same project as the interpretation of any other designed entity. [ABSTRACT FROM AUTHOR]
