Imagine a zombie world that looks “from the outside” just like ours, but where there is no phenomenal consciousness. Creatures that look like us move about just as we do and make the same noises we do, but nobody experiences or feels anything. How much of the epistemic value that’s exemplified in our world survives in that one? The short answer is: any kind of epistemic value that requires the occurrence of consciousness for its exemplification cannot exist in that world, (...) but epistemic value that doesn’t require consciousness can exist. The real question, though, is what kinds of epistemic value require the occurrence of consciousness. We will consider four central epistemic values: justification, truth, acquaintance, and understanding. (shrink)

This chapter considers how Liberal Naturalism interacts with the main problems and theories in the philosophy of perception. After briefly summarising the traditional philosophical problems of perception and outlining the standard philosophical theories of perceptual experience, it discusses whether a Liberal Naturalist outlook should incline one towards or away from any of these standard theories. Particular attention is paid to the work of John McDowell and Hilary Putnam, two of the most prominent Liberal Naturalists, whose work was also very influential (...) in the philosophy of perception. There is also a section focusing on colour, an especially important topic not only for debates about perceptual experience but also for debates concerning how our ‘manifest image’ of the natural world relates to our best theories in the physical sciences.

The time-lag argument seems to put some pressure on naïve realism to agree that seeing must happen simultaneously with what is seen; meanwhile, a wide-accepted empirical fact suggests that light takes time to transmit from objects at a distance to perceivers—which implies what is seen happened before seeing, and, accordingly, naïve realism must be false. In this paper, I will, first of all, show that the time-lag argument has in fact involves a misunderstanding concept of simultaneity: according to Special Relativity, (...) simultaneity is a matter of convention rather than a matter of fact, so, in principle, we can stipulate a perceptual conception of simultaneity, according to which what is seen is simultaneous with seeing. Secondly, the generalized time-lag argument has a mistaken view on the perceived events and perceiving; it has a doubtful assumption that these events are momentary in the mathematical sense. Such idealization is the main reason why we have the intuition that the time-lag effect of perceiving is in conflict with our ordinary perceptual experiences. Finally, I argue that the naïve realist account of the perceptual relation is a nontemporal constitutive relation; and hence naïve realism is compatible with the claim that we can perceive things as they were, and it should not be weakened by the time-lag argument.

Naïve Realism claims that veridical perceptual experiences essentially consist in genuine relations between perceivers and mind-independent objects and their features. The contemporary debate in the philosophy of perception has devoted little attention to assessing one of the main motivations to endorse Naïve Realism–namely, that it is the only view which articulates our ‘intuitive’ conception of perception. In this paper, I first clarify in which sense Naïve Realism is supposed to be ‘naïve’. In this respect, I argue that it is put (...) forward as the only view which can take our introspective knowledge of perception at face value, and I identify the two key features of such introspective knowledge. Second, I challenge the claim that one of these features-namely, that it seems as one could not be in the same perceptual state unless the putative objects of perception existed and were perceived–is introspectively evident. Consequently, I argue that a view of perceptual experience–such as Intentionalism–which denies that this feature is true of perception can still take introspection at face value. This undermines the claim that Naïve Realism is the only account which accommodates our intuitions on the nature of perception. (shrink)

How does the philosophical debate between naive realism and intentionalism relate to the psychological debate between ecological theories and constructivist theories? The participants in each debate take themselves to be doing something distinctive, but I show that characterizing the distinction is difficult: the theories in both debates use inference to the best explanation to draw contingent conclusions about the constitutive nature of perception. I argue that both debates concern the metaphysics of perception, and that philosophers of perception are wrong to (...) think that constructivist and ecological theories are engaged in a distinct and non-metaphysical task.

This paper considers whether we should believe philosophical claims on the basis of testimony in light of related debates about aesthetic and moral testimony. It is argued that we should not believe philosophical claims on testimony, and different explanations of why we should not are considered. It is suggested that the reason why we should not believe philosophical claims on testimony might be that philosophy is not truth-directed.

Recent work within such disparate research areas as the epistemology of perception, theories of well-being, animal and medical ethics, the philosophy of consciousness, and theories of understanding in philosophy of science and epistemology has featured disconnected discussions of what is arguably a single underlying question: What is the value of consciousness? The purpose of this paper is to review some of this work and place it within a unified theoretical framework that makes contributions (and contributors) from these disparate areas more (...) visible to one another.

Why think that conscious experience of reality is any more epistemically valuable than testimony about it? I argue that conscious experience of reality is epistemically valuable because it provides cognitive contact with reality. Cognitive contact with reality is a goal of experiential inquiry which does not reduce to the goal of getting true beliefs or propositional knowledge. Such inquiry has awareness of the truth-makers of one’s true beliefs as its proper goal. As such, one reason why conscious experience of reality (...) is more epistemically valuable than testimony about reality is that it gives us more epistemic goods than only true belief or propositional knowledge. I defend this view from two rival accounts. First, that while conscious experience of reality has greater value than testimony, its value is only eudaimonic. Second, that while it has greater epistemic value than testimony, this value is not distinctive: for it only promotes truth better than testimony. (shrink)

Externalism about colour phenomenology claims that the phenomenal character of colour experiences is determined by mind-independent properties of perceptual objects. The structural mismatch argument shows that physical properties of perceived mind-independent things are not similar in ways that correlate with the ways in which the phenomenal character of colour experiences are similar. Structural mismatch has thus been perceived by some to demonstrate that correlative externalism (which takes mind-independent physical properties to correlate systematically with colour phenomenology) is false. This argument is (...) defused if there are broad physical properties that can bear similarity relations that do correlate with those held by the phenomenal character of colour experiences. I defend the view that disjunctive properties can perform this role by showing that disjunctive properties can account for metamerism, the unique and binary hue distinction, and differences in perceived colours between subjects. Finally, I argue that correlative externalism is better placed than other views to explain why the physical properties identified by the physical sciences correlate with colour experiences with the particular phenomenal character they have.
