Diversity Reading List

Abstract: The subject of mental processes or mental states is usually assumed to be an individual, and hence the boundaries of mental features -  in a strict or metaphorical sense - are naturally regarded as reaching no further than the boundaries of the individual. This chapter addresses various philosophical developments in the 20th and 21st century that questioned this natural assumption. I will frame this discussion by first presenting a historically influential commitment to the individualistic nature of the mental in Descartes' theory. I identify various elements in the Cartesian conception of the mind that were subsequently criticized and rejected by various externalist theories, advocates of the extended mind hypothesis and defenders of embodied cognition. Then I will indicate the main trends in these critiques.

Abstract: Disjunctivist theories of perceptual experience claim that veridical and non-veridical experiences are radically unalike in some respect (other than the obvious difference in their causal histories). This chapter outlines four ways of elaborating this basic claim, each motivated by a different concern. The first is disjunctivism about the objects of experience, motivated by Direct Realism. The second is disjunctivism about the content of experience, motivated by the view that some experiences have object-dependent content. The third is disjunctivism about perceptual evidence (also known as epistemological disjunctivism), which is a strategy for responding to a particular sort of argument for scepticism about the external world. The fourth is disjunctivism about the metaphysical structure of experience (also known as metaphysical disjunctivism), which is motivated by Naïve Realism (a species of Direct Realism).

Abstract: Many philosophers are skeptical about disjunctivism—a theory of perceptual experience which holds roughly that a situation in which I see a banana that is as it appears to me to be (the good case) and one in which I have a hallucination as of a banana (a certain kind of bad case) are mentally completely different. Often this skepticism is rooted in the suspicion that such a view cannot adequately account for the bad case—in particular, (i) that such a view cannot explain why what it’s like to have a hallucination can be exactly like what it’s like to have a veridical experience, (ii) that it cannot explain why the hallucination I have in the bad case is subjectively indistinguishable from the kind of experience I have in the good case, and (iii) that it cannot offer a viable account of the nature of hallucination. In this paper, I argue that a proper formulation of disjunctivism can avoid these objections. Disjunctivism should be formulated as the weakest claim required to preserve its primary motivation, viz., Naïve Realism—the view that veridical experience fundamentally consists in the subject perceiving entities in her environment. And the weakest claim required to preserve Naïve Realism allows for many sorts of commonalities across the good and hallucinatory cases, commonalities that can be marshaled in responding to the objections. Most importantly, disjunctivism properly formulated is compatible with “positive” accounts of the nature of hallucination (as against M.G.F. Martin’s widely accepted argument to the contrary).
