Although the act-object analysis of experience has not enjoyed widespread support lately, Hector-Neri Castañeda embraced it completely and, in his characteristically systematic way, developed an original and deeply interesting version of it as an integral part of his general ontology (see especially Castañeda 1977, 1980). Few of those who reject the act-object analysis are able to articulate a reasonable alternative view of the ontology of experience. In this essay, I defend the only alternative that is a going concern, viz., the adverbial account.¹
