An important objection to the "higher-order" theory of consciousness turns on the possibility of higher-order misrepresentation. I argue that the objection fails because it illicitly assumes a characterization of consciousness explicitly rejected by HO theory. This in turn raises the question of what justifies an initial characterization of the data a theory of consciousness must explain. I distinguish between intrinsic and extrinsic characterizations of consciousness, and I propose several desiderata a successful characterization of consciousness must meet. I then defend the (...) particular extrinsic characterization of the HO theory, the "transitivity principle," against its intrinsic rivals, thereby showing that the misrepresentation objection conclusively falls short.

Some theorists approach the Gordian knot of consciousness by proclaiming its inherent tangle and mystery. Others draw out the sword of reduction and cut the knot to pieces. Philosopher Thomas Metzinger, in his important new book, Being No One: The Self-Model Theory of Subjectivity,1 instead attempts to disentangle the knot one careful strand at a time. The result is an extensive and complex work containing almost 700 pages of philosophical analysis, phenomenological reflection, and scientific data. The text offers a sweeping (...) and comprehensive tour through the entire landscape of consciousness studies, and it lays out Metzinger's rich and stimulating theory of the subjective mind. Metzinger's skilled integration of philosophy and neuroscience provides a valuable framework for interdisciplinary research on consciousness.

Subjective experiences take place whe n there is a conscious perspective, an active first-person point of view. It occurs in. (shrink)

The same-order representation theory of consciousness holds that conscious mental states represent both the world and themselves. This complex representational structure is posited in part to avoid a powerful objection to the more traditional higher-order representation theory of consciousness. The objection contends that the higher-order theory fails to account for the intimate relationship that holds between conscious states and our awareness of them--the theory 'divides the phenomenal labor' in an illicit fashion. This 'failure of intimacy' is exposed by the possibility (...) of misrepresentation by higher-order states. In this paper, I argue that despite appearances, the same-order theory fails to avoid the objection, and thus also has troubles with intimacy. (shrink)

s Gibson (1982) correctly points out, despite Quine’s brief flirtation with a “mitigated phenomenalism” (Gibson’s phrase) in the late 1940’s and early 1950’s, Quine’s ontology of 1953 (“On Mental Entities”) and beyond left no room for non-physical sensory objects or qualities. Anyone familiar with the contemporary neo-dualist qualia-freak-fest might wonder why Quinean lessons were insufficiently transmitted to the current generation.

David Rosenthal and Josh Weisberg have recently provided a counter argument to Ned Block’s argument that a Higher Order Thought (HOT) theory of consciousness cannot accommodate the existence of hallucinatory conscious states (i.e. a conscious episode consisting of a HOT without the presence of a relevant lower order thought). Their counter argument invokes the idea of mental appearances: a non-existent intentional object which is to aid in an account of subjective conscious awareness. I argue that if mental appearances (...) are to do the work they are supposed to, we cannot draw a mental appearance/reality distinction. I provide an alternative story that a HOT theorist can invoke to account for cases of conscious misrepresentation. Such a story will require denying the existence of hallucinatory conscious states while still accounting for conscious misrepresentation. This is a cost I believe the HOT theorist should be willing to pay. (shrink)

It is widely held that consciousness is partially constituted by a “pre-reflective” self-consciousness. Further, it’s argued that the presence of pre-reflective self-consciousness poses a problem for “higher-order” theories of consciousness. Higher-order theories invoke reflective representation and so do not appear to have the resources to explain pre-reflective self-consciousness. This criticism is rooted in the Heidelberg School’s deep reflection on the nature of self-consciousness, and accordingly, I will label this challenge the “Heidelberg problem.” In this chapter, I will offer a higher-order (...) answer to the Heidelberg problem. Instead of attacking the problem head-on, I’ll argue that the view can explain why there appears to be a Heidelberg problem, even if consciousness is ultimately realized by higher-order representation. But I’ll also argue that the theory has indexical resources to more directly counter the Heidelberg problem. Either way, I hope to show that the higher-order theory survives its trip to Heidelberg.

ABSTRCT: In this commentary, I criticize Metzinger's interdisciplinary approach to fixing the explanandum of a theory of consciousness and I offer a commonsense alternative in its place. I then re-evaluate Metzinger's multi-faceted working concept of consciousness, and argue for a shift away from the notion of "global availability" and towards the notio ns of "perspectivalness" and "transparency." This serves to highlight the role of Metzinger's "phenomenal model of the intentionality relation" (PMIR) in explaining consciousness, and it helps to locate Metzinger's (...) theory in relation to other naturalistic theories of.

Most materialist responses to the zombie argument against materialism take either a “type-A” or “type-B” approach: they either deny the conceivability of zombies or accept their conceivability while denying their possibility. However, a “type-Q” materialist approach, inspired by Quinean suspicions about a priority and modal entailment, rejects the sharp line between empirical and conceptual truths needed for the traditional responses. In this paper, I develop a type-Q response to the zombie argument, one stressing the theory-laden nature of our conceivability and (...) possibility intuitions. I argue that our first-person access to the conscious mind systematically misleads us into thinking that the distinctive qualities of conscious experience—qualia—are nonfunctional. Qualia, I contend, are functional, even though they do not seem to be. To support my claim, I introduce the “meditations” of Rene Descartes’ zombie twin. This establishes the plausibility of an appearance/reality distinction for consciousness and it undermines various anti-materialist objections based on privileged first-person access. I conclude that the best overall theory posits an appearance/reality distinction for qualia, and this, for the type-Q materialist, is decisive. (shrink)

Each of us, right now, is having a unique conscious experience. Nothing is more basic to our lives as thinking beings and nothing, it seems, is better known to us. But the ever-expanding reach of natural science suggests that everything in our world is ultimately physical. The challenge of fitting consciousness into our modern scientific worldview, of taking the subjective “feel” of conscious experience and showing that it is just neural activity in the brain, is among the most intriguing explanatory (...) problems of our times. -/- In this book, Josh Weisberg presents the range of contemporary responses to the philosophical problem of consciousness. The basic philosophical tools of the trade are introduced, including thought experiments featuring Mary the color-deprived super scientist and fearsome philosophical “zombies”. The book then systematically considers the space of philosophical theories of consciousness. Dualist and other “non-reductive” accounts of consciousness hold that we must expand our basic physical ontology to include the intrinsic features of consciousness. Functionalist and identity theories, by contrast, hold that with the right philosophical stage-setting, we can fit consciousness into the standard scientific picture. And “mysterians” hold that any solution to the problem is beyond such small-minded creatures as us. -/- Throughout the book, the complexity of current debates on consciousness is handled in a clear and concise way, providing the reader with a fine introductory guide to the rich philosophical terrain. The work makes an excellent entry point to one of the most exciting areas of study in philosophy and science today. (shrink)

Explanatory Optimism about the Hard Problem of Consciousness argues that despite the worries of explanatory pessimists, consciousness can be fully explained in “easy” scientific terms. The widespread intuition that consciousness poses a hard problem is plausibly based on how consciousness appears to us in first-person access. The book offers a debunking argument to undercut the justificatory link between the first-person appearances and our hard problem intuitions. -/- The key step in the debunking argument involves the development and defense of an (...) empirical model of first-person access: Automated Compression Theory (ACT). ACT holds that first-person access to consciousness is accomplished by automated accessing of compressed sensory information. Because of the distorting nature of this compressed access, it seems to subjects that consciousness possesses “exceptional” properties—properties leading to the hard problem—even though no such properties are present. If there are no exceptional properties to explain, then an explanation in easy terms can fully account for conscious experience. The book presents a range of empirical evidence for ACT and concludes that the burden of proof is now on the pessimists to show why we shouldn’t be optimistic about explaining consciousness.

When you have ruled everything else out, then what you are left with, no matter how improbable, must be the truth. This adage from Doyle describes the path taken by Leopold Stubenberg in his book, Consciousness and Qualia.

He delivers a bold and simple slogan (...) that distills the essence of his view: “To be conscious is to have qualia” (262). (shrink)

Over the last quarter century or so, no one has done more to shape debate in the philosophy of mind and cognitive science than Jerry Fodor. He is best known for championing the Computational Theory of Mind (CTM), the view that thinking consists of computations over syntactically structured mental representations (Fodor, 1975).

Josh Weisberg discusses what he calls the “Heidelberg Problem” (named after Dieter Henrich’s Heidelberg School). However, he mischaracterizes this problem and believes he is able so resolve the problem, as mischaracterized, as well as meet the de se constraint, in the theoretical frame of reference of the Higher-Order Thought Monitoring theory of consciousness. This commentary highlights the fundamental flaw in his approach, while encouraging further philosophical exchange with our American philosophical colleagues about the “Heidelberg Problem”.

I have learned a lot from Josh Weisberg’s substantial criticism in his well-crafted and systematic commentary. Unfortunately, I have to concede many of the points he intelligently makes. But I am also flattered by the way he ultimately uses his criticism to emphasize some of those aspects of the theory that can perhaps possibly count as exactly the core of my own genuine contribution to the problem—and nicely turns them back against myself. And I am certainly grateful for (...) a whole range of helpful clarifications. (shrink)

This is my reply to Josh Weisberg, Robert Van Gulick, and William Seager, published in JCS vol 20, 2013. This symposium grew out of an author-meets-critics session at the Central APA conference in 2013 on my 2012 book THE CONSCIOUSNESS PARADOX (MIT Press). Topics covered include higher-order thought (HOT) theory, my own "wide intrinsicality view," the problem of misrepresentation, targetless HOTs, conceptualism, introspection, and the transitivity principle.

Modelers often rely on robustness analysis, the search for predictions common to several independent models. Robustness analysis has been characterized and championed by Richard Levins and William Wimsatt, who see it as central to modern theoretical practice. The practice has also been severely criticized by Steven Orzack and Elliott Sober, who claim that it is a nonempirical form of confirmation, effective only under unusual circumstances. This paper addresses Orzack and Sober's criticisms by giving a new account of robustness analysis and (...) showing how the practice can identify robust theorems. Once the structure of robust theorems is clearly articulated, it can be shown that such theorems have a degree of confirmation, despite the lack of direct empirical evidence for their truth.

Reformulating a scientific theory often leads to a significantly different way of understanding the world. Nevertheless, accounts of both theoretical equivalence and scientific understanding have neglected this important aspect of scientific theorizing. This essay provides a positive account of how reformulation changes our understanding. My account simultaneously addresses a serious challenge facing existing accounts of scientific understanding. These accounts have failed to characterize understanding in a way that goes beyond the epistemology of scientific explanation. By focusing on cases in which (...) we have differences in understanding without differences in explanation, I show that understanding does not reduce to explanation. (shrink)

I want to join Dummett in saying that the reality of the past (and, by analogy, the reality of the future) is an issue of realism versus anti-realism: (Dummett 1969) If you affirm the reality of the past, you are a realist about the past. If you deny the reality of the past, you are an anti-realist about the past. (And likewise, in each case, for the future). It makes sense to think of these issues by analogy with realism about (...) the external world, unobservable objects, mathematical objects, universals, and so on.

Initiatives relying on artificial intelligence (AI) to deliver socially beneficial outcomes—AI for social good (AI4SG)—are on the rise. However, existing attempts to understand and foster AI4SG initiatives have so far been limited by the lack of normative analyses and a shortage of empirical evidence. In this Perspective, we address these limitations by providing a definition of AI4SG and by advocating the use of the United Nations’ Sustainable Development Goals (SDGs) as a benchmark for tracing the scope and spread of AI4SG. (...) We introduce a database of AI4SG projects gathered using this benchmark, and discuss several key insights, including the extent to which different SDGs are being addressed. This analysis makes possible the identification of pressing problems that, if left unaddressed, risk hampering the effectiveness of AI4SG initiatives. (shrink)

Is the ability to speak a language an acquired skill? Leading proponents of the generative approach to human language—notably Chomsky (2000) and Pinker (2003)—have argued that the thesis that language capacities are skills is hopelessly confused and at odds with a range of empirical evidence, which suggests that human language capacities are grounded in a biologically inherited set of language instincts or a Universal Grammar (UG). In this paper, we argue that resistance to the claim that human language capacities are (...) skills has been fostered by naïve and implausible conceptions of the nature of skilled action. Correcting these misconceptions about the nature of skilled action breathes new life into the old idea that human language competences are particular kinds of skills and does so in a way that is fully consistent with appeals to the central importance of UG, broadly construed. More generally, we argue that by taking human language capacities to be skills, we capture what is right about the generative program while at the same time avoiding its most serious pitfalls.

Science frequently gives us multiple, compatible ways of solving the same problem or formulating the same theory. These compatible formulations change our understanding of the world, despite providing the same explanations. According to what I call "conceptualism," reformulations change our understanding by clarifying the epistemic structure of theories. I illustrate conceptualism by analyzing a typical example of symmetry-based reformulation in chemical physics. This case study poses a problem for "explanationism," the rival thesis that differences in understanding require ontic explanatory differences. (...) To defend conceptualism, I consider how prominent accounts of explanation might accommodate this case study. I argue that either they do not succeed, or they generate a skeptical challenge. (shrink)

We argue that Hamiltonian mechanics is more fundamental than Lagrangian mechanics. Our argument provides a non-metaphysical strategy for privileging one formulation of a theory over another: ceteris paribus, a more general formulation is more fundamental. We illustrate this criterion through a novel interpretation of classical mechanics, based on three physical conditions. Two of these conditions suffice for recovering Hamiltonian mechanics. A third condition is necessary for Lagrangian mechanics. Hence, Lagrangian systems are a proper subset of Hamiltonian systems. Finally, we provide (...) a geometric interpretation of the principle of stationary action and rebut arguments for privileging Lagrangian mechanics. (shrink)

Science and mathematics continually change in their tools, methods, and concepts. Many of these changes are not just modifications but progress---steps to be admired. But what constitutes progress? This dissertation addresses one central source of intellectual advancement in both disciplines: reformulating a problem-solving plan into a new, logically compatible one. For short, I call these cases of compatible problem-solving plans "reformulations." Two aspects of reformulations are puzzling. First, reformulating is often unnecessary. Given that we could already solve a problem using (...) an older formulation, what do we gain by reformulating? Second, some reformulations are genuinely trivial or insignificant. Merely replacing one symbol with another does not lead to intellectual progress. What distinguishes significant reformulations from trivial ones? According to what I call "conceptualism" (or "conceptual empiricism"), reformulations are intellectually significant when they provide a different plan for solving problems. Significant reformulations provide inferentially different routes to the same solution. In contrast, trivial reformulations provide exactly the same problem-solving plans, and hence they do not change our understanding. This answers the second question about what distinguishes trivial from significant reformulations. However, the first question remains: what makes a new way of solving an old problem valuable? Here, a bevy of practical considerations come to mind: one formulation might be faster, less complicated, or use more familiar concepts. According to "instrumentalism," these practical benefits are all there is to reformulating. Some reformulations are simply more instrumentally valuable for meeting the aims of science than others. At another extreme, "fundamentalism" contends that a reformulation is valuable when it provides a more fundamental description of reality. According to this view, some reformulations directly contribute to the metaphysical aim of carving reality at its joints. Conceptualism develops a middle ground between instrumentalism and fundamentalism, preserving their benefits without their costs. I argue that the epistemic value of significant reformulations does not reduce to either practical or metaphysical value. Reformulations are valuable because they are a constitutive part of problem-solving. Both science and mathematics aim at solving all possible problems within their respective domains. Meeting this aim requires being able to plan for any possible problem-solving context, and this requires reformulating. By reformulating, we clarify what we need to know to solve problems. Still, one might wonder whether the value of reformulations requires underlying differences in explanatory power. According to "explanationism," a reformulation is valuable only when it provides a better explanation. Explanationism stands as a rival middle ground position to my own. However, it faces numerous counterexamples. In many cases, two reformulations provide the same explanation while nonetheless providing different ways of understanding a phenomenon. Hence, reformulating can be valuable even when neither formulation is more explanatory. Methodologically, I draw on a variety of case studies to support my account of reformulation. These range from classical mechanics to quantum chemistry, along with examples from mathematics. Symmetry arguments provide a paradigmatic example: the mathematics of symmetry groups radically recasts quantum mechanics and quantum chemistry. Nevertheless, elementary approaches exist that eschew this additional mathematical apparatus, solving problems in a more tedious but less mathematically-demanding manner. Further examples include reformulations of quantum field theory, Arabic vs. Roman numerals, and Fermat's little theorem in number theory. In each case, my account identifies how reformulations change and improve our understanding of science and mathematics. (shrink)
