In this paper, I develop and defend a new adverbial theory of perception. I first present a semantics for direct-object perceptual reports that treats their object-positions as supplying adverbial modifiers, and I show how this semantics definitively solves the many-property problem for adverbialism. My solution is distinctive in that it articulates adverbialism from within a well-established formal semantic framework and ties adverbialism to a plausible semantics for perceptual reports in English. I then go on to present adverbialism as a theory of the metaphysics of perception. The metaphysics I develop treats adverbial perception as a directed activity: it is an activity with success conditions. When perception is successful, the agent bears a relation to a concrete particular, but perception need not be successful; this allows perception to be fundamentally non-relational. The result is a novel formulation of adverbialism that eliminates the need for representational contents, but also treats successful and unsuccessful perceptual events as having a fundamental common factor.

Moral life sometimes involves life-and-death decisions, and philosophers often consider them by examining intuitions about ideal cases. Contemporary philosophical discourse on such matters has been dominated by Trolley-type cases, which typically present us with the need to make decisions on whether to sacrifice one person in order to save a larger number of similar others. Such cases lead to a distinct view of moral dilemmas and of moral life generally. The case I present here, “Hostage Situation,” is quite unlike them and should generate intuitions that differ greatly from those brought forth by standard Trolley-type cases. The implications are surprising and suggest that familiar and widely prevalent perceptions of the normative field are inadequate.
