Abstract

Abstract Disjunctivism is the view that we must give different explanations for genuine perceptual experience and for perceptual illusions and hallucinations. Some contemporary scholars have argued that Nyāya philosophy of perception is disjunctivist. This chapter disagrees with this claim, and demonstrates that, for Nyāya, seeing is uniform. The entire point of the Nyāya discussion of illusion is that an absent feature is mistakenly presented as-present. The perceptual experience is, therefore, erroneous, precisely because something which is actually absent is presented-as-actually-present. But, insofar as this feature is one with which the perceiver is presentationally acquainted, the experience remains firmly within the orbit of relationalism. Nyāya relationalism supplies a uniform analysis of the nature of perceptual experiences.
