Abstract

Christian von Ehrenfels’s foremost contribution to philosophy of mind is undeniably his seminal 1890 article on Gestalt qualities. This work is considered to have been a “watershed” (Smith 1988b, 15) and a “revolution” (Smith 1994, 20). Ehrenfels’ notion of Gestalt resonated not only with his contemporaries, in the School of Brentano and in phenomenology (see e.g. Heinämaa 2009), but it continues to inform cognitive science (see e.g. Wildgen 2001) and philosophy of mind. In this chapter I will outline some of the influences and background of his conception, briefly discuss his notion of Gestalt, explain how it was taken up by others, and then consider how Ehrenfels himself further applied and developed it.
