A major obstacle to the acceptance of materialist theories of the mind is the problem of sensory consciousness. How could a physical brain produce conscious sensory states that exhibit the rich and luxurious qualities of red velvet, a Mozart concerto or fresh-brewed coffee? A full answer to this question requires two different sorts of theory. The first sort considers what all these conscious sensory states have in common, by virtue of being conscious as opposed to unconscious states. The second sort considers what distinguishes conscious sensory-states from each other, for example, how the qualities in a conscious sensory state of red velvet differ from those of a Mozart concerto. I propose a theory of the first sort, that is, an explanation of the distinction between conscious and unconscious sensory states. ;According to the second sense theory, conscious sensory states are coordinated sensory representations of the present moment produced by a second sense. Three elements are necessary and jointly sufficient for sensory consciousness. Sensory representations must be coordinated toward action in the world. The representations included in the content of a conscious sensory state are those that will aid the creature in assessing current environmental conditions according to the task at hand. Conscious sensory states represent states of affairs as occurring at the present moment. In other words, sensory consciousness is constituted by the coordination of sensory representations into a representation of what is happening 'now.' The mechanism responsible for coordinating sensory representations into conscious sensory states is the second sense. A second sense mechanism explains how some sensory representations become coordinated into a conscious sensory state while others remain unconscious. ;In addition to providing an explanation of sensory consciousness, the second sense theory is nicely suited to a Gibsonian account of subjectivity, whereby information about the subject is specified simultaneously in perception with information about the object. I argue that the subject, at its most bare, is the locus of an egocentric map, the zero point of a coordinate system which specifies objects according to here

Philosophical theories of memory rarely distinguish between importantly different sorts of memory: procedural, semantic and episodic. I argue for a temporal representation theory to explain the unique characteristic of episodic memory as the only form of conscious memory. A careful distinction between implicit and explicit representation shows how the past figures in memory. In procedural and semantic memory, the influence of the past is implicit by which I mean that the past experience is used but not represented in the skill or knowledge. Episodic memory, in contrast, depends on representing a past experience as past. On a temporal representation theory of consciousness, a conscious state represents the present moment, and in the case of episodic memory, it includes a representation of past experience. The embedded account of the ‘feeling of pastness’ takes past experience to be part of the explicit content of a conscious state. An episodic memory is a representation of the present that includes a representation of the past. Whereas a higher-order theory of consciousness can give no reason why only episodic memories are conscious, a temporal theory explains why episodic memories are both higher-order and conscious. Finally, I consider the essential role of episodic memory in the formation of a temporally extended self. The demands of a social environment motivate development of an ability to track the mental states of others and oneself over time. By incorporating past experience (and future experience) into the present, episodic memory extends experience in time to form the sense of self. Through a careful examination of the function of temporal representation, we can see why the past is not consciously represented in procedural and semantic memory and the value of consciously representing the past in episodic memory.

A major obstacle for materialist theories of the mind is the problem of sensory consciousness. How could a physical brain produce conscious sensory states that exhibit the rich and luxurious qualities of red velvet, a Mozart concerto or fresh-brewed coffee? Caging the Beast: A Theory of Sensory Consciousness offers to explain what these conscious sensory states have in common, by virtue of being conscious as opposed to unconscious states. After arguing against accounts of consciousness in terms of higher-order representation of mental states, the theory claims that sensory consciousness is a special way we have of representing the world. The book also introduces a way of thinking about subjectivity as separate and more fundamental than consciousness, and considers how this foundational notion can be developed into more elaborate varieties. An appendix reviews the connection between consciousness and attention with an eye toward providing a neuropsychological instantiation of the proposed theory.

Does neuroscience show that free will is an illusion? No, it shows that unconscious mental states are causally effective in action. Because free will includes initiation by both conscious and unconscious states, the self as free agent should be characterized in terms of more than her conscious deliberations to range over unconscious beliefs, memories and feelings. Further, the ways social relations influence action and the ways actions influence the social environment are relevant to a full account of free will. Given this broader perspective, it is clear that recent neuroscientific studies only show that the conscious feeling of volition does not play the agential role it seems to play. Consciousness is nonetheless causally effective in planning and monitoring actions to ensure they conform to goals. This causal process unfolds over a span of time and encompasses a wide array of factors

Self-conflict is a feature of most women’s lives, particularly as we struggle to balance the demands of work and family. Theories of autonomy that rest on a notion of a coherent self treat self-conflict as incompatible with autonomy; therefore, women who suffer self-conflict fail to act autonomously. Though autonomy and self-conflict can be accommodated by conceiving of autonomy as a matter of degree relative to a context of choice, this result sanctions a political system that forces the prioritization of one context over another. Yet choices in one context often compromise choices in another context, creating a situation where acting autonomously simultaneously diminishes autonomy. Given that autonomous choice justifies political liberalism, it is unjust that choices are set against one another in this way. Consequently, the burden on liberal governments to address the structural sources of self-conflict is far greater than is often supposed.

Consciousness has a peculiar affinity for presence; conscious states represent their contents as now. To understand how conscious states come to represent time in this way, we need a distinction between a mental state that represents now and one that simply occurs now. A teleofunctional theory accounts for the distinction in terms of the development and function of explicit temporal representation. The capacity to represent a situation explicitly as ‘now’ and compare it with past situations in order to prepare for the future involves the separation of goals from the particular action required to attain them. That is, when a creature is able to consider alternative paths of action, it becomes necessary to conceive of alternate future times as distinct from the present moment. The developmental, functional approach of a teleofunctional theory is promising in its ability to integrate research from diverse empirical fields for support of its claims
