Prinz In this dissertation I defend a theory of perceptual consciousness titled “Quantum Uncertainty Reduction” (QUR1) Theory of Attended Access and Phenomenal Consciousness.” Consciousness is widely perceived as a phenomenon that poses a special explanatory problem for science. The problem arises in the apparent rift between an immediate first-person acquaintance with consciousness and our lack of ability to provide an objective/scientific third- person characterization of consciousness. I begin by reviewing philosophical ideas of Ned Block, David Chalmers and Jesse Prinz whose characterizations of consciousness provide a conceptual framework that the proposed theory aims to satisfy. Block and Chalmers argue that consciousness is a mongrel concept combining two distinct aspects: access and phenomenal consciousness, while Jesse Prinz’s argues for the central role of attention in engendering consciousness. Since the proposed solution is an aspect of quantum information processing in a mechanism, I discuss and adopt methodological approach of the use of mechanisms in scientific explanations developed by William Bechtel, Carl Craver and others. I outline a mechanism based on Shannon 1 Pronounced as “cure.” iv Communication System and enhanced with Bayesian predictive processing developed by Carl Friston, Jacob Hohwy, and Andy Clark as well as Control Theory by Rick Grush. Based on views of Marcin Miłkowski, Gualtiero Piccinini and others on information processing in physical systems, I argue that the suggested mechanism implements physical information processing or computation. After a brief overview of relevant aspects of quantum theory, I review recent developments that aim to reconstruct quantum theory by using epistemic approach to explain the nature of quantum states vs. the traditional ontic one. I adopt the epistemic approach and argue that by performing a functional analysis of physical computation in the suggested mechanism we can identify a certain process as involving processing/manipulation of quantum and classical information. I further suggest that the central aspect of the process, namely, quantum uncertainty reduction gives rise to qualitative properties of phenomenal and access consciousness. Further, I compare the suggested information processing formulation of Access and Phenomenal consciousness with those of Block and Chalmers, that are, correspondingly, non- functional and non-physical. I argue that my conceptualization is preferable since it gives a functional and physical account of phenomenal and access consciousness while accommodating thought experiments that Block and Chalmers use to argue for their views on consciousness. Finally, while largely agreeing with the where and when of consciousness of Prinz’s AIR (Attended Intermediate Representations) theory of consciousness, QUR theory offers new arguments for an extended where and more nuanced when of phenomenal consciousness. v Acknowledgements Portions of this dissertation were presented at the CUNY Graduate Center Cognitive Science Symposium and Discussion Group, Towards a Science of Consciousness, and The New Jersey Regional Philosophy Association.

    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by PhilPapers Forthcoming in Trends in Cognitive Sciences What is wrong with the no-report paradigm and how to fix it Ned Block New York University Correspondence: [email protected] Key words: consciousness, perception, rivalry, frontal, global workspace, higher order Abstract Is consciousness based in prefrontal circuits involved in cognitive processes like thought, reasoning, and memory or, alternatively, is it based in sensory areas in the back of the neocortex? The no-report paradigm has been crucial to this debate because it aims to separate the neural basis of the cognitive processes underlying post-perceptual decision and report from the neural basis of conscious perception itself. However, the no-report paradigm is problematic because, even in the absence of report, subjects might engage in post-perceptual cognitive processing. Therefore, to isolate the neural basis of consciousness, a no-cognition paradigm is needed. Here, I describe a no-cognition approach to binocular rivalry and outline how this approach can help resolve debates about the neural basis of consciousness.

What is the Neural Basis of Consciousness? In recent years the scientific study of consciousness (see Glossary) has focused on finding the neural basis of consciousness in the brain. There are many theories of the neural basis of consciousness, but in broad strokes theories tend to divide on whether consciousness is rooted in the ‘front’ or the ‘back’ of the brain.

  • Consciousness, Philosophical Issues About Ned Block New York University I
    To appear in The Encyclopedia of Cognitive Science Consciousness, Philosophical Issues about Ned Block New York University I. The Hard Problem There are a number of different matters that come under the heading of ‘consciousness’. One of them is phenomenality, the feeling of say a sensation of red or a pain, that is what it is like to have such a sensation or other experience. Another is reflection on phenomenality. Imagine two infants, both of which have pain, but only one of which has a thought about that pain. Both would have phenomenal states, but only the latter would have a state of reflexive consciousness. This entry will start with phenomenality, moving later to reflexivity and then to one other kind of consciousness. The Hard Problem of consciousness is how to explain a state of consciousness in terms of its neurological basis. If neural state N is the neural basis of the sensation of red, why is N the basis of that experience rather than some other experience or none at all? Chalmers (1996) distinguishes between the Hard Problem and “easy” problems that concern the function of consciousness. The Hard Problem (though not under that name) was identified by Nagel (1974) and further analyzed in Levine (1983). There are two reasons for thinking that the Hard Problem has no solution. 1. Actual Failure. In fact, no one has been able to think of even a highly speculative answer. 2. Principled Failure. The materials we have available seem ill suited to providing an answer. As Nagel says, an answer to this question would seem to require an objective account that necessarily leaves out the subjectivity of what it is trying to explain.

Splitting Concepts* Gualtiero Piccinini and Sam Scott†‡ A common presupposition in the concepts literature is that concepts constitute a sin- gular natural kind. If, on the contrary, concepts split into more than one kind, this literature needs to be recast in terms of other kinds of mental representation. We offer two new arguments that concepts, in fact, divide into different kinds: (a) concepts split because different kinds of mental representation, processed independently, must be posited to explain different sets of relevant phenomena; (b) concepts split because different kinds of mental representation, processed independently, must be posited to explain responses to different kinds of category. Whether these arguments are sound remains an open empirical question, to be resolved by future empirical and theoretical work. 1. Introduction. In the past 35 years, psychologists, philosophers, and linguists have generated a vast interdisciplinary literature on the nature of concepts. This literature has produced three main families of psycho- logical theories: the prototype, exemplar, and theory theories of concepts (e.g., Hampton [1993] for prototypes, Nosofsky [1988] for exemplars, and Gopnik and Meltzoff [1997] for theories).

  • The Mystery of David Chalmers
    Daniel C. Dennett The Mystery of David Chalmers 1. Sounding the Alarm ‘The Singularity’ is a remarkable text, in ways that many readers may not appreciate. It is written in an admirably forthright and clear style, and is beautifully organized, gradually introducing its readers to the issues, sorting them carefully, dealing with them all fairly and with impressive scholarship, and presenting the whole as an exercise of sweet reasonableness, which in fact it is. But it is also a mystery story of sorts, a cunningly devised intellectual trap, a baffling puzzle that yields its solution — if that is what it is (and that is part of the mystery) — only at the very end. It is like a ‘well made play’ in which every word by every character counts, retrospectively, for something. Agatha Christie never concocted a tighter funnel of implications and suggestions. Bravo, Dave. Copyright (c) Imprint Academic 2013 So what is going on in this essay? It purports to be about the pros- pects of the Singularity, and since I can count on readers of my essay For personal use only -- not for reproduction to have read Chalmers, I needn’t waste so much as a sentence on what that is or might be. See Chalmers (2010). I confess that I was initially repelled by the prospect of writing a commentary on this essay since I have heretofore viewed the Singularity as a dismal topic, involving reflections on a technological fantasy so far removed from actuality as to be an indulgence best resisted. Life is short, and there are many serious problems to think about.

  • Advertisement for a Semantics for Psychology
    MIDWEST STUDIES IN PHILOSOPHY, X (1986) Advertisement for a Semantics for Psychology NED BLOCK eaning is notoriously vague. So, it should not be surprising that se- Mmanticists (those who study meaning) have had somewhat different purposes in mind, and thus have sharpened the ordinary concept of meaning in somewhat different ways. It is a curious and unfortunate fact that semanti- cists typically tell us little about what aspects of meaning they are and are not attempting to deal with. One is given little guidance as to what extent “rival” research programs actually disagree. My purpose here is to advocate an approach to semantics relevant to the foundations of psychology, or, rather, one approach to one branch of psychology, namely cognitive science. I shall be tallung in terms of some of the leading ideas of cognitive science, most importantly the representational theory of mind, aspects of which will be sketched as they become relevant.’ The representalist doctrine that my argument depends on is that thoughts are structured entities. I know this will be a sticking point for some readers, so I will say a bit more about what this comes to, and I will compare my position with related positions that reject it. My strategy will be to begin with some desiderata. These desiderata vary along many dimensions: how central they are to meaning, how psycho- logically oriented they are, how controversial they are. I will argue that one approach to semantics (not to keep you in suspense-conceptual role seman- tics) promises to handle such desiderata better than the others that I know about.

  • Consciousness, Accessibility, and the Mesh Between Psychology and Neuroscience
    BEHAVIORAL AND BRAIN SCIENCES (2007) 30, 481–548 Printed in the United States of America doi: 10.1017/S0140525X07002786 Consciousness, accessibility, and the mesh between psychology and neuroscience Ned Block Department of Philosophy, New York University, New York, NY 10003 [email protected] Abstract: How can we disentangle the neural basis of phenomenal consciousness from the neural machinery of the cognitive access that underlies reports of phenomenal consciousness? We see the problem in stark form if we ask how we can tell whether representations inside a Fodorian module are phenomenally conscious. The methodology would seem straightforward: Find the neural natural kinds that are the basis of phenomenal consciousness in clear cases – when subjects are completely confident and we have no reason to doubt their authority – and look to see whether those neural natural kinds exist within Fodorian modules. But a puzzle arises: Do we include the machinery underlying reportability within the neural natural kinds of the clear cases? If the answer is “Yes,” then there can be no phenomenally conscious representations in Fodorian modules. But how can we know if the answer is “Yes”? The suggested methodology requires an answer to the question it was supposed to answer! This target article argues for an abstract solution to the problem and exhibits a source of empirical data that is relevant, data that show that in a certain sense phenomenal consciousness overflows cognitive accessibility. I argue that we can find a neural realizer of this overflow if we assume that the neural basis of phenomenal consciousness does not include the neural basis of cognitive accessibility and that this assumption is justified (other things being equal) by the explanations it allows.

  • How to Explain Miscomputation
    volume 18, no. 24 Introduction december 2018 Just as a theory of representation is deficient if it can’t explain how misrepresentation is possible, a theory of computation is deficient if it can’t explain how miscomputation is possible. You might expect, then, that philosophers of computation have well-worked-out theories of miscomputation. But you’d be wrong. They have generally ignored miscomputation.1 How to Explain My primary goal in this paper is to clarify both what miscompu- tation is and what needs to be accomplished in order to adequately explain it. Miscomputation is a special kind of malfunction. If the bat- tery breaks, a system may fail to compute what it is supposed to com- Miscomputation pute. But it’s not miscomputing, because it’s not computing at all. Just as something doesn’t misrepresent unless it represents, something doesn’t miscompute unless it computes. To miscompute is to com- pute in a way that violates a computational norm. Consequently, an adequate account of miscomputation requires an account of what the system is computing when the system is violating the relevant compu- tational norms. A secondary goal is to defend an individualist approach to miscom- putation. The advantage of this account is that it provides a simple and straightforward explanation of miscomputation. Piccinini contends that, by appealing to teleological functions, his externalist account Chris Tucker also enjoys this advantage. It does not. Not yet, anyway. Following just College of William & Mary about every discussion of functional individuation, Piccinini focuses on how to individuate proper function.2 I focus instead on how to indi- viduate actual function.

  • The Varieties of Computation: a Reply
    The Varieties of Computation: A Reply David J. Chalmers I am grateful to the twelve commentators on my article “A Computational Foundation for the Study of Cognition”. The commentaries reflect a great deal of thought by authors many of whom have thought about this topic in more depth than I have in recent years. In many cases, they raise issues that I did not anticipate when I wrote the article and that require me to rethink various aspects of the account I gave there.1 Publication of this symposium, almost twenty years after writing the paper, has encouraged me to dig into my records to determine the article’s history. The roots of the article lie in a lengthy e-mail discussion on the topic of “What is Computation?”, organized by Stevan Harnad in 1992. I was a graduate student in Doug Hofstadter’s AI laboratory at Indiana University at that point and vigorously advocated what I took to be a computationalist position against skeptics. Harnad suggested that the various participants in that discussion write up “position papers” to be considered for publication in the journal Minds and Machines. I wrote a first draft of the article in December 1992 and revised it after reviewer comments in March 1993. I decided to send a much shorter article on implementation to Minds and Machines and to submit a further revised version of the full article to Behavioral and Brain Sciences in April 1994. I received encouraging reports from BBS later that year, but for some reason (perhaps because I was finishing a book and then moving from St.

  • Computation Without Representation1
    Philosophical Studies (2006) Ó Springer 2006 DOI 10.1007/s11098-005-5385-4 GUALTIERO PICCININI COMPUTATION WITHOUT REPRESENTATION1 ABSTRACT. The received view is that computational states are individu- ated at least in part by their semantic properties. I offer an alternative, according to which computational states are individuated by their func- tional properties. Functional properties are specified by a mechanistic explanation without appealing to any semantic properties. The primary purpose of this paper is to formulate the alternative view of computational individuation, point out that it supports a robust notion of computational explanation, and defend it on the grounds of how computational states are individuated within computability theory and computer science. A sec- ondary purpose is to show that existing arguments for the semantic view are defective. 1. THE PROBLEM OF COMPUTATIONAL INDIVIDUATION In some fields, such as computer science and cognitive sci- ence, there are scientific theories that explain the capacities of a mechanism À respectively, the computer and the brain À by appealing to the computations it performs. This paper per- tains to the individuation of computational states, inputs, and outputs within such scientific theories. For short, I will main- ly talk about computational states; the same conclusions ap- ply to computational inputs and outputs. The received view is that ‘‘[t]here is no computation with- out representation’’ (Fodor 1981, p. 180). The reason usually given is that computational states are individuated, or taxon- omized, by their semantic properties. The same point is sometimes made by saying that computational states have their content essentially.2 I call this the semantic view of com- putational individuation.
