ABSTRACT
This chapter first explains two implications of Fred Dretske's nomological, objectivist view of information that stand in an interesting but not immediately obvious relation to each other. It discusses three theories of perception that are markedly at variance with each other in these respects: David Marr's computational view of visual perception, Gibson's ecological approach to visual perception as the former's main antagonist and the main focus of attention in the chapter, and the Empirical Strategy of perception as a contemporary theory of intermediate status, which endorses the notion of context-boundedness of perception while relying on computational models. The issues of illusion and misperception are also discussed. The chapter discusses how to account for illusion and misperception if information is an objective commodity and perception is the activity of tracking the relations that make up that commodity.
