Though the following problem is not explicitly raised by her, it seems sufficiently similar to an issue of pertinence to Akins's "Black and White and Color" (this volume) to merit the moniker, Akins's Problem : Can there be a visual experience devoid of both color phenomenology and black-and-white phenomenology? The point of the present paper is to draw from Akins's paper the materials needed to sketch a case for a positive answer to Akins's Problem. I am unsure about how much of what follows Akins will want to endorse, but I hope this helps move us forward in our collective pursuit of a theory of visual consciousness.

In this paper I explore the question of how artificial life might be used to get a handle on philosophical issues concerning the mind-body problem. I focus on questions concerning what the physical precursors were to the earliest evolved versions of intelligent life. I discuss how cellular automata might constitute an experimental platform for the exploration of such issues, since cellular automata offer a unified framework for the modeling of physical, biological, and psychological processes. I discuss what it would take to implement in a cellular automaton the evolutionary emergence of cognition from non-cognitive artificial organisms. I review work on the artificial evolution of minimally cognitive organisms and discuss how such projects might be translated into cellular automata simulations.

I argue against a class of philosophical views of color perception, especially insofar as such views posit the existence of color sensations. I argue against the need to posit such nonconceptual mental intermediaries between the stimulus and the eventual conceptualized perceptual judgment. Central to my arguments are considerations of certain color illusions. Such illusions are best explained by reference to high-level, conceptualized knowledge concerning, for example, object identity, likely lighting conditions, and material composition of the distal stimulus. Such explanations obviate the need to appeal to nonconceputal mental links in the causal chains eventuating in conceptualized color discriminations.

Cognitive Science is a major new guide to the central theories and problems in the study of the mind and brain. The authors clearly explain how and why cognitive science aims to understand the brain as a computational system that manipulates representations. They identify the roots of cognitive science in Descartes - who argued that all knowledge of the external world is filtered through some sort of representation - and examine the present-day role of Artificial Intelligence, computing, psychology, linguistics and neuroscience. Throughout, the key building blocks of cognitive science are clearly illustrated: perception, memory, attention, emotion, language, control of movement, learning, understanding and other important mental phenomena. Cognitive Science: presents a clear, collaborative introduction to the subject is the first textbook to bring together all the different strands of this new science in a unified approach includes illustrations and exercises to aid the student

I argue for the superiority of non-gappy physicalism over gappy physicalism. While physicalists are united in denying an ontological gap between the phenomenal and the physical, the gappy affirm and the non-gappy deny a relevant epistemological gap. Central to my arguments will be contemplation of Swamp Mary, a being physically intrinsically similar to post-release Mary (a physically omniscient being who has experienced red) but has not herself (the Swamp being) experienced red. Swamp Mary has phenomenal knowledge of a phenomenal character not instantiated by any of her past or current mental states. I issue a challenge to gappy physicalists to account for how it is that Swamp Mary can satisfy the psychosemantic requirements on phenomenal knowledge while non-Swamp pre-release Mary cannot. I argue that gappy physicalists cannot meet this psychosemantic challenge.

I develop an argument that believing in the survivability of a mind uploading procedure conveys value to its believers that is assessable independently of assessing the truth of the belief. Regardless of whether the first-order metaphysical belief is true, believing it conveys a kind of Darwinian fitness to the believer. Of course, a further question remains of whether having that Darwinian property can be a basis—in a rational sense of being a basis—for one’s holding the belief. I’ll also make some remarks in the present article toward answering that latter question.

I develop advice to the reductionist about consciousness in the form of a transcendental argument that depends crucially on the sorts of knowledge claims concerning consciousness that, as crucial elements in the anti-reductionists’ epistemicgap arguments, the anti-reductionist will readily concede. The argument that I develop goes as follows. P1. If I know that I am not a zombie, then phenomenal character is (a certain kind of) conceptualized egocentric content. P2. I know that I am not a zombie. P3. Phenomenal character is (a certain kind of) conceptualized egocentric content. P4. Fixing my physical properties fixes my conceptualized egocentric contents. C. Fixing my physical properties fixes my phenomenal properties.

Is the Introspection Thesis true? It certainly isn’t obvious. Introspection is the faculty by which each of us has access to his or her own mental states. Even if we were to suppose that mental states are identical to brain states, it doesn’t follow immediately from this supposition that we can introspect our mental states as brain states. This point is analogous to the following. It doesn’t follow immediately from the mere fact that some distant object is identical to a horse that we can perceive it as a horse. Further, it isn’t obvious that any amount of education would suffice to make some distant speck on the horizon seem like a horse. It may very well be the case that no matter how well we know that some distant speck is a horse; as long as we are sufficiently distant from it we will only be able to see it as a speck. Analogously then, it may very well be the case that no matter how well we know that our mental states are brain states, we will only be able to introspect them as irreducibly mental

A movement dedicated to applying neuroscience to traditional philosophical problems and using philosophical methods to illuminate issues in neuroscience began about twenty-five years ago. Results in neuroscience have affected how we see traditional areas of philosophical concern such as perception, belief-formation, and consciousness. There is an interesting interaction between some of the distinctive features of neuroscience and important general issues in the philosophy of science. And recent neuroscience has thrown up a few conceptual issues that philosophers are perhaps best trained to deal with. After sketching the history of the movement, we explore the relationships between neuroscience and philosophy and introduce some of the specific issues that have arisen.

The philosophical technical term "supervenience" is frequently used in the philosophy of mind as a concise way of characterizing the core idea of physicalism in a manner that is neutral with respect to debates between reductive physicalists and nonreductive physicalists. I argue against this alleged neutrality and side with reductive physicalists. I am especially interested here in debates between psychoneural reductionists and nonreductive functionalist physicalists. Central to my arguments will be considerations concerning how best to articulate the spirit of the idea of supervenience. I argue for a version of supervenience, "fine-grained supervenience," which is the claim that if, at a given time, a single entity instantiates two distinct mental properties, it must do so in virtue of instantiating two distinct physical properties. I argue further that despite initial appearances to the contrary, such a construal of supervenience can be embraced only by reductive physicalists

The majority of contemporary philosophers of mind are physicalists. The majority of physicalists, however, are non-reductive physicalists. As nonreductive physicalists, these philosophers hold that a system's mental properties are different from a system's physical properties, that is, they hold that the sum total of mental facts about some system is a different set of facts than the sum total of physical facts about the same system. As physicalists, however, these nonreductivists hold that mental facts are nonetheless determined by physical facts, that is, they subscribe to the supervenience thesis, i.e., the thesis that no mental differences can obtain without physical differences obtaining. In this paper I take up the issue of how best to understand the notion of supervenience, especially in the light of recent advances in the neurosciences

This article tackles problems concerning the reduction of phenomenal consciousness to brain processes that arise in consideration of specifically epistemological properties that have been attributed to conscious experiences. In particular, various defenders of dualism and epiphenomenalism have argued for their positions by assuming special epistemic access to phenomenal consciousness. Many physicalists have reacted to such arguments by denying the epistemological premises. My aim in this paper is to take a different approach in opposing dualism and argue that when we correctly examine both the phenomenology and neural correlates of phenomenal consciousness we will see that granting the epistemological premises of special access are the best hope for a scientific study of consciousness. I argue that essential features of consciousness involve both their knowability by the subject of experience as well as their egocentricity, that is, their knowability by the subject as belonging to the subject. I articulate a neuroscientifically informed theory of phenomenal consciousness

Computation and philosophy intersect three times in this essay. Computation is considered as an object, as a method, and as a model used in a certain line of philosophical inquiry concerning the relation of mind to matter. As object, the question considered is whether computation and related notions of mental representation constitute the best ways to conceive of how physical systems give rise to mental properties. As method and model, the computational techniques of artificial life and embodied evolutionary connectionism are used to conduct prosthetically enhanced thought experiments concerning the evolvability of mental representations. Central to this essay is a discussion of the computer simulation and evolution of three-dimensional synthetic animals with neural network controllers. The minimally cognitive behavior of finding food by exhibit- ing positive chemotaxis is simulated with swimming and walking creatures. These simulations form the basis of a discussion of the evolutionary and neurocomputa- tional bases of the incremental emergence of more complex forms of cognition. Other related work has been used to attack computational and representational theories of cognition. In contrast, I argue that the proper understanding of the evolutionary emergence of minimally cognitive behaviors is computational and representational through and through.

According to representionalists, qualia-the introspectible properties of sensory experience-are exhausted by the representational contents of experience. Representationalists typically advocate an informational psychosemantics whereby a brain state represents one of its causal antecedents in evolutionarily determined optimal circumstances. I argue that such a psychosemantics may not apply to certain aspects of our experience, namely, our experience of space in vision, hearing, and touch. I offer that these cases can be handled by supplementing informational psychosemantics with a procedural psychosemantics whereby a representation is about its effects instead of its causes. I discuss conceptual and empirical points that favor a procedural representationalism for our experience of space.

Many have urged that the biggest obstacles to a physicalistic understanding of consciousness are the problems raised in connection with the subjectivity of consciousness. These problems are most acutely expressed in consideration of the knowledge argument against physicalism. I develop a novel account of the subjectivity of consciousness by explicating the ways in which mental representations may be perspectival. Crucial features of my account involve analogies between the representations involved in sensory experience and the ways in which pictorial representations exhibit perspectives or points of view. I argue that the resultant account of subjectivity provides a basis for the strongest response physicalists can give to the knowledge argument

  In this paper I discuss one of the key issuesin the philosophy of neuroscience:neurosemantics. The project of neurosemanticsinvolves explaining what it means for states ofneurons and neural systems to haverepresentational contents. Neurosemantics thusinvolves issues of common concern between thephilosophy of neuroscience and philosophy ofmind. I discuss a problem that arises foraccounts of representational content that Icall ``the economy problem'': the problem ofshowing that a candidate theory of mentalrepresentation can bear the work requiredwithin in the causal economy of a mind and anorganism. My approach in the current paper isto explore this and other key themes inneurosemantics through the use of computermodels of neural networks embodied and evolvedin virtual organisms. The models allow for thelaying bare of the causal economies of entireyet simple artificial organisms so that therelations between the neural bases of, forinstance, representation in perception andmemory can be regarded in the context of anentire organism. On the basis of thesesimulations, I argue for an account ofneurosemantics adequate for the solution of theeconomy problem

Control consciousness is the awareness or experience of seeming to be in control of one’s actions. One view, which I will be arguing against in the present paper, is that control consciousness is a form of sensory consciousness. In such a view, control consciousness is exhausted by sensory elements such as tactile and proprioceptive information. An opposing view, which I will be arguing for, is that sensory elements cannot be the whole story and must be supplemented by direct contributions of nonsensory, motor elements. More specifically, I will be arguing for the view that the neural basis of control consciousness is constituted by states of recurrent activation in relatively intermediate levels of the motor hierarchy

This is Philosophy. In keeping with the mission of the series, This is Philosophy: Philosophy of Mind will be both accessible to the average student and technology oriented, integrating with supplemental online material. Also, while the proposed book will cover all of the topics one would expect in a traditional philosophy of mind course, it will be up to date and cover recent advances that are sadly missing from many competitor volumes. My proposed volume will not be limited to what has become a very oldfashioned approach to teaching philosophy of mind, which is to focus solely on the mindbody problem via Cartesian substance dualism and the twentieth-century reactions to it (behaviorism, identity theory, functionalism, and eliminativism). In recent decades philosophers of mind have made exciting progress toward, for example, explanations of consciousness, and explications of the nature of perception and emotion. It is increasingly clear that the progress made is now part of canonical philosophy of mind

The present paper has three aims. The first and foremost aim is to introduce into philosophy of mind and related areas (philosophy of language, etc) a discussion of Slow Earth, an analogue to the classic Twin Earth scenario that features a difference from aboriginal Earth that hinges on time instead of the distribution of natural kinds. The second aim is to use Slow Earth to call into question the central lessons often alleged to flow from consideration of Twin Earth, lessons having to do with relations of minds to spatially definable boundaries of bodies such as skin or skull. The third aim is to suggest a puzzle for adherents of cognitive content externalism having to do with the metaphysical requirements on slow-switching, a hypothetical process whereby changes in the relations between subjects and their environments are followed by gradual changes in cognitive contents

00192001 Philosophy of science is primarily concernedto provide accounts of the principles and processes of scientific explanation. Early in the twentieth century, philosophers of science focusedon the logical structure of scientific thought, whereas in the later part of the century logic was de-emphasized in favour of other frameworks for conceptualizing scientific reasoning andexplanation, andan emphasis on historical andsociological factors that shape scientific thinking. While tracing through the landmarks of this history we note many points of contact between the philosophy of science and the cognitive sciences

The neurophilosophy of consciousness brings neuroscience to bear on philosophical issues concerning phenomenal consciousness, especially issues concerning what makes mental states conscious, what it is that we are conscious of, and the nature of the phenomenal character of conscious states. Here attention is given largely to phenomenal consciousness as it arises in vision. The relevant neuroscience concerns not only neurophysiological and neuroanatomical data, but also computational models of neural networks. The neurophilosophical theories that bring such data to bear on the core philosophical issues of phenomenal conscious construe consciousness largely in terms of representations in neural networks associated with certain processes of attention and memory
