Higher‐Order Thought and the Problem of Radical Confabulation

Currently, one of the most influential theories of consciousness is Rosenthal's version of higher‐order‐thought (HOT). We argue that the HOT theory allows for two distinct interpretations: a one‐component and a two‐component view. We further argue that the two‐component view is more consistent with his effort to promote HOT as an explanatory theory suitable for application to the empirical sciences. Unfortunately, the two‐component view seems incapable of handling a group of counterexamples that we refer to as cases of radical confabulation. We begin by introducing the HOT theory and by indicating why we believe it is open to distinct interpretations. We then proceed to show that it is incapable of handling cases of radical confabulation. Finally, in the course of considering various possible responses to our position, we show that adoption of a disjunctive strategy, one that would countenance both one‐component and two‐component versions, would fail to provide any empirical or explanatory advantage.     

Epistemic Warrants and Higher‐Order Theories of Conscious Perception

We present a new account of perceptual consciousness, one which gives due weight to the epistemic commitment of normal perception in familiar circumstances. The account is given in terms of a higher‐order attitude for which the subject has an immediate perceptual epistemic warrant in the form of an appropriate first‐order perception. We develop our account in contrast to Rosenthal's higher‐order account, rejecting his view of consciousness in virtue of so‐called ‘targetless’ higher‐order states. We explain the key notion of an immediate perceptual warrant and show both that it requires the content of the higher‐order attitude to match that of the first‐order perception, and also that it gives a new perspective on the intimate relationship, rightly emphasised by Rosenthal, between consciousness and a subject's testimony as to ‘how it is with her’.     

Degrees of consciousness

Is a human more conscious than an octopus? In the science of consciousness, it's oftentimes assumed that some creatures (or mental states) are more conscious than others. But in recent years, a number of philosophers have argued that the notion of degrees of consciousness is conceptually confused. This paper (1) argues that the most prominent objections to degrees of consciousness are unsustainable, (2) examines the semantics of ‘more conscious than’ expressions, (3) develops an analysis of what it is for a degreed property to count as degrees of consciousness, and (4) applies the analysis to various theories of consciousness. I argue that whether consciousness comes in degrees ultimately depends on which theory of consciousness turns out to be correct. But I also argue that most theories of consciousness entail that consciousness comes in degrees.     

Colour Discrimination And Monitoring Theories of Consciousness

According to the monitoring theory of consciousness, a mental state is conscious in virtue of being represented in the right way by a monitoring state. David Rosenthal, William Lycan, and Uriah Kriegel have developed three different influential versions of this theory. In order to explain colour experiences, each of these authors combines his version of the monitoring theory of consciousness with a specific account of colour representation. Even though Rosenthal, Lycan, and Kriegel disagree on the specifics, they all hold that colours are represented by a single type of mental state. The main goal of this paper is to show that a more complex account of colour representation is needed for the monitoring theory of consciousness to do justice to the phenomenology of colour experiences. In particular, I will argue that the fine-grained character of colour experience—that is, the fact that perceivers can become conscious of small differences between colours—requires that colour representation be construed in terms of two different types of mental states, namely sensory states that represent appearance properties and colour representations that represent physical colours.     

The persistent problem of targetless thought

Targetless thought raises a persistent problem for higher-order theories of consciousness. In cases of targetless thought, a subject represents herself as being in a mental state that she in fact lacks. One popular response among proponents of the higher-order theory is to say that it can appear to a subject that she is in a conscious mental state, even though that mental state doesn’t exist (Picciuto, 2017; Rosenthal 1997, 2011; Weisberg, 2010). Recently Brown and Lau (2019) and Lau and Rosenthal (2011) have shifted the debate to empirical ground, and offered evidence for real-world cases of targetless thought. In this paper, I give an alternate explanation of the evidence which avoids the need to posit targetless thoughts. As I argue, this challenges the empirical argument for the higher-order view because it shows that the evidence on offer does not discriminate between the first-order and higher-order theories of consciousness.     

Fiction,Pleasurable Tragedy,and the HOT Theory of Consciousness

Abstract

The ‘feeling fiction problem’ asks: is it rational to be moved by what happens to fictional characters? The so-called ‘paradox of tragedy’ is embodied in the question: Why or how is it that we take pleasure in artworks which are clearly designed to cause in us such feelings as sadness and fear? My focus in this paper is to examine these problems from the point of view of the so-called ‘higher-order thought theory of consciousness’ (HOT theory) which says that the best explanation for what makes a mental state conscious is that it is accompanied by a thought that one is in that state. I examine the feeling fiction problem in light of the HOT theory and through a critique of Colin Radford's view. For example, I argue that Radford equivocates in his use of the term ‘aware’ in his response to some of the proposed solutions to the feeling fiction problem. Finally, I show how Susan Feagin's approach to the paradox of tragedy can be analysed and supported by the HOT theory.     

Intentions are mental states

Richard Scheer has recently argued against what he calls the ‘mental state’ theory of intentions. He argues that versions of this theory fail to account for various characteristics of intention. In this essay we reply to Scheer's criticisms and argue that intentions are mental states.     

Drop it like it’s HOT: a vicious regress for higher-order thought theories

Higher-order thought (HOT) theories of consciousness attempt to explain what it takes for a mental state to be conscious, rather than unconscious, by means of a HOT that represents oneself as being in the state in question. Rosenthal (in: Liu, Perry (eds) Consciousness and the self: new essays, Cambridge University Press, Cambridge, 2011) stresses that the way we are aware of our own conscious states requires essentially indexical self-reference. The challenge for defenders of HOT theories is to show that there is a way to explain the required reference-fixing mechanisms that is compatible with the theory. According to Rosenthal, the reference to oneself as such is grounded in the disposition to identify the individual the HOT refers to as the individual who has that HOT. I argue that this leads to a vicious infinite regress on the more than plausible assumption that our cognitive capacities are limited. This leaves such theories without a foundation, since self-reference is thought essential to consciousness.

     

Fine-Grained Colour Discrimination without Fine-Grained Colour

René Jagnow [2012] argues that David Rosenthal's theory of consciousness cannot account for certain experiences that involve colours so fine-grained that we do not and cannot have concepts of them. Jagnow claims that an appeal to comparative concepts such as being slightly darker than cannot help Rosenthal, since, in order to apply such concepts, we would already need to be conscious of two distinct fine-grained colours. The present paper contests this claim. It appeals to the Cornsweet illusion and some other visual phenomena, in order to argue that our visual systems can and do represent brutely comparative matters.     

Nietzsche on the Nature of the Unconscious

Abstract

This paper argues that Nietzsche develops a novel and compelling account of the distinction between conscious and unconscious mental states: he argues that conscious mental states are those with conceptual content, whereas unconscious mental states are those with nonconceptual content. I show that Nietzsche’s puzzling claim that consciousness is ‘superficial’ and ‘falsifying’ can be given a straightforward explanation if we accept this understanding of the conscious/unconscious distinction. I originally defended this view in my ‘Nietzsche’s Theory of Mind: Consciousness and Conceptualization’ (2005, European Journal of Philosophy 13: 1–31); since then, the view has come under criticism on several fronts. Brian Leiter and others suggest that there is not enough textual evidence for the view. In addition, Leiter, Mattia Riccardi and Tsarina Doyle argue that, rather than aligning the conscious/unconscious distinction with the conceptual/nonconceptual distinction, Nietzsche endorses a higher-order thought model of consciousness. Riccardi also objects that Nietzsche must treat some unconscious mental states as conceptual. In this essay, I defend the interpretation in light of these objections. I provide new textual evidence for the interpretation, show that Nietzsche extracted aspects of the view from Schopenhauer’s work on consciousness, consider the possibility that Nietzsche endorses a higher-order thought theory, and respond to Riccardi’s objection.     

How many kinds of consciousness?

Ned Block's influential distinction between phenomenal and access consciousness has become a staple of current discussions of consciousness. It is not often noted, however, that his distinction tacitly embodies unargued theoretical assumptions that favor some theoretical treatments at the expense of others. This is equally so for his less widely discussed distinction between phenomenal consciousness and what he calls reflexive consciousness. I argue that the distinction between phenomenal and access consciousness, as Block draws it, is untenable. Though mental states that have qualitative character plainly differ from those with no mental qualities, a mental state's being conscious is the same property for both kinds of mental state. For one thing, as Block describes access consciousness, that notion does not pick out any property that we intuitively count as a mental state's being conscious. But the deeper problem is that Block's notion of phenomenal consciousness, or phenomenality, is ambiguous as between two very different mental properties. The failure to distinguish these results in the begging of important theoretical questions. Once the two kinds of phenomenality have been distinguished, the way is clear to explain qualitative consciousness by appeal to a model such as the higher-order-thought hypothesis.     

Simulation and Irrationality

Abstract

In this paper, I hope to show how a recent theory in the philosophy of mind concerning how we ‘read’ the minds of others—namely, Heal's version of simulation theory—is consistent with the view that the kind of understanding we bring to bear on the irrational is different in kind from the way we understand one another in the course of everyday life. I shall attempt to show that Heal's version of simulation theory (co-cognition) is to be favoured over its rival ‘theory theories’ in the light of its accommodation of deeply irrational mental states. I claim that simulation theory preserves an asymmetry of psychological explanation which is not similarly preserved by a theory theory account, and I argue that this preservation of asymmetry is an advantage of Heal's account.     

Towards a New Feeling Theory of Emotion

According to the old feeling theory of emotion, an emotion is just a feeling: a conscious experience with a characteristic phenomenal character. This theory is widely dismissed in contemporary discussions of emotion as hopelessly naïve. In particular, it is thought to suffer from two fatal drawbacks: its inability to account for the cognitive dimension of emotion (which is thought to go beyond the phenomenal dimension), and its inability to accommodate unconscious emotions (which, of course, lack any phenomenal character). In this paper, I argue that the old feeling theory is in reality only a pair of modifications removed from a highly plausible account of the nature of emotion that retains the essential connection between emotion and feeling. These modifications are, moreover, motivated by recent developments in work on phenomenal consciousness. The first development is the rising recognition of a phenomenal character proper to cognition—so‐called cognitive phenomenology. The second is the gathering momentum behind various ‘connection principles’ that specify some connection that a given state must bear to phenomenally conscious states in order to qualify as mental. These developments make it possible to formulate a new feeling theory of emotion, which would overcome the two fatal drawbacks of the old feeling theory. According to the new feeling theory, an emotion is a mental state that bears the right connection to conscious experiences with the right phenomenal character (involving, among other elements, a cognitive phenomenology).     

Prefrontal lesion evidence against higher-order theories of consciousness

According to higher-order theories of consciousness, a mental state is conscious only when represented by another mental state. Higher-order theories must predict there to be some brain areas (or networks of areas) such that, because they produce (the right kind of) higher-order states, the disabling of them brings about deficits in consciousness. It is commonly thought that the prefrontal cortex produces these kinds of higher-order states. In this paper, I first argue that this is likely correct, meaning that, if some higher-order theory is true, prefrontal lesions should produce dramatic deficits in visual consciousness. I then survey prefrontal lesion data, looking for evidence of such deficits. I argue that no such deficits are to be found, and that this presents a compelling case against higher-order theories.     

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.     

Same old, same old: the same-order representation theory of consciousness and the division of phenomenal labor

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. A version of this paper was presented at the ‘Self-Representational Approaches to Consciousness’ conference, Center for Consciousness Studies, University of Arizona, March 18th–20th, 2005.     

Brentano's Dual‐Framing Theory of Consciousness

Brentano's theory of consciousness has garnered a surprising amount of attention in recent philosophy of mind (Thomasson 2000 , Caston 2002, Hossack 2002, 2006, Kriegel 2003a, 2003b, 2009, Thomas 2003 , Smith 2004 , Zahavi 2004, Drummond 2006, Textor 2006, 2013 ). Here I argue for a novel interpretation of Brentano's theory that casts it as more original than previously appreciated and yet quite plausible upon inspection. According to Brentano's theory, as interpreted here, a conscious experience of a tree is a mental state that can be simultaneously thought of, or framed, equally accurately as (i) an awareness of a tree or (ii) an awareness of an awareness of a tree.     

Phenomenal consciousness with infallible self-representation

In this paper, I argue against the claim recently defended by Josh Weisberg that a certain version of the self-representational approach to phenomenal consciousness cannot avoid a set of problems that have plagued higher-order approaches. These problems arise specifically for theories that allow for higher-order misrepresentation or—in the domain of self-representational theories—self-misrepresentation. In response to Weisberg, I articulate a self-representational theory of phenomenal consciousness according to which it is contingently impossible for self-representations tokened in the context of a conscious mental state to misrepresent their objects. This contingent infallibility allows the theory to both acknowledge the (logical) possibility of self-misrepresentation and avoid the problems of self-misrepresentation. Expanding further on Weisberg’s work, I consider and reveal the shortcomings of three other self-representational models—put forward by Kreigel, Van Gulick, and Gennaro—in order to show that each indicates the need for this sort of infallibility. I then argue that contingent infallibility is in principle acceptable on naturalistic grounds only if we attribute (1) a neo-Fregean kind of directly referring, indexical content to self-representational mental states and (2) a certain ontological structure to the complex conscious mental states of which these indexical self-representations are a part. In these sections I draw on ideas from the work of Perry and Kaplan to articulate the context-dependent semantic structure of inner-representational states.     

What It's Like To Have a Cognitive Home

Many people believe that the mind is an epistemic refuge of sorts. The idea is that when it comes to certain core mental states, one's being in such a state automatically puts one in a position to know that one is in that state. This idea has come under attack in recent years. One particularly influential attack comes from Timothy Williamson (2000), who argues that there is no central core of states or conditions—mental or otherwise—to which we are guaranteed epistemic access. In Williamson's words, we are cognitively homeless. In this paper I will argue that Williamson's argument for the conclusion that we are cognitively homeless fails. Then I will show that there is a class of phenomenal states that constitutes a substantial cognitive refuge. When all is said and done, I will have both defended and shed light on our cognitive home.     

Consciousness,Higher-Order Content,and the Individuation of Vehicles

One of the distinctive properties of conscious states is thepeculiar self-awareness implicit in them. Two rival accounts of this self-awareness are discussed. Accordingto a Neo-Brentanian account, a mental state M is conscious iff M represents its very own occurrence.According to the Higher-Order Monitoring account, M is merely accompanied by a numerically distinctrepresentation of its occurrence. According to both, then, M is conscious in virtue of figuring in a higher-ordercontent. The disagreement is over the question whether the higher-order content is carried by Mitself or by a different state. While theNeo-Brentanian theory is phenomenologically more attractive, it isoften felt to be somewhat mysterious. It is argued (i) that the difference between the Neo-Brentanian andHigher-Order Monitoring theories is smaller and more empirical than may initially seem, and (ii) that theNeo-Brentanian theory can be readily demystified. These considerations make it prima faciepreferable to the Higher-Order Monitoring theory.
