Abstract
In his last book, Gibson (1979/1986) clearly described crucial elements for an ontology for ecological psychology, but left his overarching ontology implicit and incomplete. As a partial remedy, Turvey (1992) presented a compact, well- packaged outline of an ontology for ecological psychology derived in part from the work of Bunge. In appreciation of Turvey's pioneering and thought-provoking attack on this difficult issue, we offer our own reflections on Turvey's propertied realism. In reviewing Turvey's work we use both the insights of Heidegger and recent experimental findings in ecological psychology to argue for the need for a different ontological foundation. We argue that a Heideggerian ontology can provide us with a broader and more complete ontological foundation with which to deal with complex issues, such as prospective control, than can Turvey's proposed ontology. Also, we suggest that a Heideggerian ontology can be used to supply what is missing or understated in Gibson. We argue against propertied realism as a basis for ecological psychology's ontology and contend that a proper conception of intentionality provides a way to transcend traditional object-subject ontologies. We propose that fields should be considered real ontological entities that differ from matter. Finally, we reflect on how the highly nonscientific language of Heidegger might possibly be formalized to make it more suitable for scientific use.
