Shoemaker on Phenomenal Content

Sydney Shoemaker has given a sophisticated theory of phenomenal content, motivated by the transparency of experience and by the possibility of spectrum inversion without illusion (1994, 2000, 2001, 2002). It centers on the idea that color experiences represent what he calls “appearance properties”. I consider the different sorts of appearance properties that Shoemaker has suggested might enter into phenomenal content – occurrent appearance properties, dispositional appearance properties, and higher-order dispositional appearance properties – and argue that none of them are plausibly represented by color experiences. I argue that Shoemaker's theory faces a dilemma – either it makes misperception too difficult, or it does not truly accommodate veridical spectrum inversion. I then examine some alternative Russellian theories of phenomenal content that might be consistent with Shoemaker's motivations, including a different sort of proposal recently suggested by Shoemaker (forthcoming). I argue that these views are also lacking, for similar reasons as the appearance property view. Finally, I conclude that in order for a representationalist theory to properly accommodate spectrum inversion without illusion, phenomenal content must include an indexical element. Such a view requires the adoption of a broadly Fregean theory of phenomenal content, according to which sameness of phenomenal character does not entail sameness in extension. What phenomenally identical experiences have in common is not what they represent, but how they represent.     

Kant on Complete Determination and Infinite Judgement

In the Transcendental Ideal Kant discusses the principle of complete determination: for every object and every predicate A, the object is either determinately A or not-A. He claims this principle is synthetic, but it appears to follow from the principle of excluded middle, which is analytic. He also makes a puzzling claim in support of its syntheticity: that it represents individual objects as deriving their possibility from the whole of possibility. This raises a puzzle about why Kant regarded it as synthetic, and what his explanatory claim means. I argue that the principle of complete determination does not follow from the principle of excluded middle because the externally negated or ‘negative’ judgement ‘Not (S is P)’ does not entail the internally negated or ‘infinite’ judgement ‘S is not-P.’ Kant's puzzling explanatory claim means that empirical objects are determined by the content of the totality of experience. This entails that empirical objects are completely determinate if and only if the totality of experience has a completely determinate content. I argue that it is not a priori whether experience has such a completely determinate content and thus not analytic that objects obey the principle of complete determination.     

Sensory consciousness explained (better) in terms of ‘corporality’ and ‘alerting capacity’

How could neural processes be associated with phenomenal consciousness? We present a way to answer this question by taking the counterintuitive stance that the sensory feel of an experience is not a thing that happens to us, but a thing we do: a skill we exercise. By additionally noting that sensory systems possess two important, objectively measurable properties, corporality and alerting capacity, we are able to explain why sensory experience possesses a sensory feel, but thinking and other mental processes do not. We are additionally able to explain why different sensory feels differ in the way they do.     

Consciousness as sensory quality and as implicit self-awareness

When a mental state is conscious – in the sense that there is something it is like for the subject to have it – it instantiates a certain property F in virtue of which it is a conscious state. It is customary to suppose that F is the property of having sensory quality. The paper argues that this supposition is false. The first part of the paper discusses reasons for thinking that unconscious mental states can have a sensory quality, for example in cases of absent-minded perception. If unconscious mental states can have a sensory quality, then sensory quality is an insufficient condition for consciousness. The second part of the paper argues that there are even better reasons to think that sensory quality is an unnecessary condition for consciousness. The idea is that mental states can be conscious even when they lack sensory quality, for example, in the case of certain conscious propositional attitudes. In the third part of the paper, an alternative to the rejected supposition, drawn from the phenomenological tradition, is offered: that consciousness is a matter of implicit self-awareness, rather than of sensory quality. According to this alternative, a mental state is conscious when, and only when, it involves implicit self-awareness.     

The representational theory of phenomenal character: A phenomenological critique

According to a currently popular approach to the analysis of phenomenal character mandates that the phenomenal character of an experience is entirely determined by, and is in fact identical with, the experience’s representational content. Two underlying assumptions motivate this approach to phenomenal character: (1) that conscious experiences are diaphanous or transparent, in the sense that it is impossible to discern, via introspection, any intrinsic features of an experience of x that are not experienced as features of x; and (2) that the immediate objects of consciousness are not objects per se, but rather properties. This paper explores these assumptions, advancing the thesis that each is rejectable on phenomenological grounds.     

Kant's transcendental idealism and contemporary anti‐realism

This paper compares Kant's transcendental idealism with three main groups of contemporary anti‐realism, associated with Wittgenstein, Putnam, and Dummett, respectively. The kind of anti‐realism associated with Wittgenstein has it that there is no deep sense in which our concepts are answerable to reality. Associated with Putnam is the rejection of four main ideas: theoryindependent reality, the idea of a uniquely true theory, a correspondence theory of truth, and bivalence. While there are superficial similarities between both views and Kant's, I find more significant differences. Dummettian anti‐realism, too, clearly differs from Kant's position: Kant believes in verification‐transcendent reality, and transcendental idealism is not a theory of meaning or truth. However, I argue that part of the Dummettian position is extremely useful for understanding part of Kant's position – his idealism about the appearances of things. I argue that Kant's idealism about appearances can be expressed as the rejection of experiencetranscendent reality with respect to appearances.     

Phenomenology and the project of naturalization

In recent years, more and more people have started talking about the necessity of reconciling phenomenology with the project of naturalization. Is it possible to bridge the gap between phenomenological analyses and naturalistic models of consciousness? Is it possible to naturalize phenomenology? Given the transcendental philosophically motivated anti-naturalism found in many phenomenologists such a naturalization proposal might seem doomed from the very start, but in this paper I will examine and evaluate some possible alternatives.     

Phenomenal transparency and cognitive self-reference

A representationalist analysis of strong first-person phenomena is developed (Baker 1998), and it is argued that conscious, cognitive self-reference can be naturalized under this representationalist analysis. According to this view, the phenomenal first-person perspective is a condition of possibility for the emergence of a cognitive first-person perspective. Cognitive self-reference always is reference to the phenomenal content of a transparent self-model. The concepts of phenomenal transparency and introspection are clarified. More generally, I suggest that the concepts of phenomenal opacity and phenomenal transparency are interesting instruments for analyzing conscious, self-representational content, and that their relevance in understanding reflexive, i.e., cognitive subjectivity may have been overlooked in the past.     

WHAT IS CONSCIOUSNESS AND HAS IT EVOLVED?

Research into consciousness has now become respectable, and much has been written about it. Is consciousness the exclusive property of human beings, or can it be found also in animals? Can machines become conscious? Is consciousness an illusion, and are all mental states ultimately reducible to the movement of molecules? If consciousness is other than matter, what connection does it have with matter? These and others like them are now serious scientific questions in the West. This article discusses consciousness within the frame of the following assertions: Consciousness has evolved from earlier states of awareness to be found in lower forms of life. The current scientific method is too restrictive for the study of conscience and its evolution. In particular classical logic leads scientists to ignore or reject consciousness as a legitimate field of study. Mind and matter, generalized as knowing and being, have equal status.     

Panpsychism,The Combination Problem,and Plural Collective Properties

Panpsychism claims that each fundamental entity is conscious, but then faces the problem of how such entities combine to make up our ordinary consciousness. In this paper, I show how panpsychism can avoid this so-called combination problem by taking seriously plural collective properties at the fundamental level.     

Why Are Some Phenomenal Experiences ‘Vivid’ and Others ‘Faint’? Representationalism,Imagery, and Cognitive Phenomenology

One central brand of representationalism claims that the specific phenomenal character of an experience is fully determined by its content. A challenge for this view is that cognitive and perceptual experiences sometimes seem to have the same representational content while differing in phenomenal character. In particular, it might seem that one can have faint imagery experiences or conscious thoughts with the same contents as vivid perceptual experiences. This paper argues that such cases never arise, and that they are probably metaphysically impossible. I also suggest a fully representational account of differences in vividness between phenomenal experiences.
