Critics have often misunderstood the higher-order theory (HOT) of consciousness. Here we clarify its position on several issues, and distinguish it from other views such as the global workspace theory (GWT) and early sensory models, such as first-order local recurrency theory. The criticism that HOT over- intellectualizes conscious experience is inaccurate because in reality the theory assumes minimal cognitive functions for consciousness; in this sense it is an intermediate position between GWT and early sensory views, and plausibly accounts for shortcomings (...) of both. Further, compared to other existing theories, HOT can more readily account for complex everyday experiences, such as of emotions and episodic memories, and make HOT potentially useful as a framework for conceptualizing pathological mental states.

In this paper I argue that a priori arguments fail to present any real problem for physicalism. They beg the question against physicalism in the sense that the argument will only seem compelling if one is already assuming that qualitative properties are nonphysical. To show this I will present the reverse-zombie and reverse-knowledge arguments. The only evidence against physicalism is a priori arguments, but there are also a priori arguments against dualism of exactly the same variety. Each of these parity (...) arguments has premises that are just as intuitively plausible, and it cannot be the case that both the traditional scenarios and the reverse-scenarios are all ideally conceivable. Given this one set must be merely prima facie conceivable and only empirical methods will tell us which is which. So, by the time a priori methodology will be of any use it will be too late.

One popular approach to theorizing about phenomenal consciousness has been to connect it to representations of a certain kind. Representational theories of consciousness can be further sub-divided into first-order and higher-order theories. Higher-order theories are often interpreted as invoking a special relation between the first-order state and the higher-order state. However there is another way to interpret higher-order theories that rejects this relational requirement. On this alternative view phenomenal consciousness consists in having suitable higher-order representations. I call this ‘HOROR’ (‘Higher-Order (...) Representation Of a Representation’) theory to distinguish it from relational versions of higher- order theory. In this paper I make the case that HOROR theory is a plausible account of the real nature of phenomenal consciousness whatever one’s views are about whether it is physical/reducible or not. I first clarify HOROR theory and compare it to the more traditional same-order and higher-order thought theories. Afterwards I move to presenting some considerations in favor of HOROR theory.

In this paper I examine the dispute between Hakwan Lau, Ned Block, and David Rosenthal over the extent to which empirical results can help us decide between first-order and higher-order theories of consciousness. What emerges from this is an overall argument to the best explanation against the first-order view of consciousness and the dispelling of the mythological notion of phenomenological overflow that comes with it.

We discuss cases where subjects seem to enjoy conscious experience when the relevant first-order perceptual representations are either missing or too weak to account for the experience. Though these cases are originally considered to be theoretical possibilities that may be problematical for the higher-order view of consciousness, careful considerations of actual empirical examples suggest that this strategy may backfire; these cases may cause more trouble for first-order theories instead. Specifically, these cases suggest that (I) recurrent feedback loops to V1 are (...) most likely not the neural correlate of first-order representations for conscious experience, (II) first-order views seem to have a problem accounting for the phenomenology in these cases, and either (III) a version of the ambitious higher-order approach is superior in that it is the simplest theory that can account for all results at face value, or (IV) a view where phenomenology is jointly determined by both first-order and higher-order states. In our view (III) and (IV) are both live options and the decision between them may ultimately be an empirical question that cannot yet be decided. (shrink)

Among our conscious states are conscious thoughts. The question at the center of the recent growing literature on cognitive phenomenology is this: In consciously thinking P, is there thereby any phenomenology—is there something it’s like? One way of clarifying the question is to say that it concerns whether there is any proprietary phenomenology associated with conscious thought. Is there any phenomenology due to thinking, as opposed to phenomenology that is due to some co-occurring sensation or mental image? In this paper (...) we will present two arguments that a “yes” answer to this question of cognitive phenomenology can be obtained via appeal to the HOT theory of consciousness, especially the version articulated and defended by David Rosenthal.

Emotional states of consciousness, or what are typically called emotional feelings, are traditionally viewed as being innately programed in subcortical areas of the brain, and are often treated as different from cognitive states of consciousness, such as those related to the perception of external stimuli. We argue that conscious experiences, regardless of their content, arise from one system in the brain. On this view, what differs in emotional and non-emotional states is the kind of inputs that are processed by a (...) general cortical network of cognition, a network essential for conscious experiences. Although subcortical circuits are not directly responsible for conscious feelings, they provide non-conscious inputs that coalesce with other kinds of neural signals in the cognitive assembly of conscious emotional experiences. In building the case for this proposal, we defend a modified version of what is known as the higher-order theory of consciousness. (shrink)

In recent times we have seen an explosion in the amount of attention paid to the conscious brain from scientists and philosophers alike. One message that has emerged loud and clear from scientific work is that the brain is a dynamical system whose operations unfold in time. Any theory of consciousness that is going to be physically realistic must take account of the intrinsic nature of neurons and brain activity. At the same time a long discussion on consciousness among philosophers (...) has resulted in our distinguishing several kinds of consciousness. So when we ask where the place of consciousness is in nature we may mean several different things. In this chapter I will argue that it is plausible that all of the kinds of consciousness turn out to be nothing but patterns of synchronized neural activity in various frequencies against a dynamically changing chemical background.

Philosophers have been talking about brain states for almost 50 years and as of yet no one has articulated a theoretical account of what one is. In fact this issue has received almost no attention and cognitive scientists still use meaningless phrases like 'C-fiber firing' and 'neuronal activity' when theorizing about the relation of the mind to the brain. To date when theorists do discuss brain states they usually do so in the context of making some other argument with the (...) result being that any discussion of what brain states are has a distinct en passant flavor. In light of this it is a goal of mine to make brain states the center of attention by providing some general discussion of them. I briefly look at the argument of Bechtel and Mundale, as I think that they expose a common misconception philosophers had about brain states early on. I then turn to briefly examining Polger's argument, as I think he offers an intuitive account of what we expect brain states to be as well as a convincing argument against a common candidate for knowledge about brain states that is currently "on the scene." I then introduce a distinction between brain states and states of the brain: Particular brain states occur against background states of the brain. I argue that brain states are patterns of synchronous neural firing, which reflects the electrical face of the brain; states of the brain are the gating and modulating of neural activity and reflect the chemical face of the brain.

At this point in time the two-dimensional (2D) argument against physicalism is well known (Chalmers 2009; 2010), as are the many responses to it. However there has been a recent development that has yet to be widely discussed. Some philosophers have argued that we have equally compelling reasons to think that dualism is false based on the conceivability of mere physical duplicates which enjoy conscious experience in just the way we do (Martin 1998; Sturgeon 2000; Piccinini 2006; Frankish 2007; Brown (...) 2010; Balog MS). This argument has not yet been properly understood and in this paper I aim to correct the most common misunderstandings. (shrink)

This highly technical book is densely packed with arguments and is an important addition to the literature. Even if one ultimately disagrees with Chalmers there is much to be gained in his exhaustive study, and he goes out of his way to show how one can accept limited or modified versions of scrutability. It is impossible for me to do justice to his argumentative rigor and comprehensive coverage of possible views in the space I have here. In the end I (...) find much of what Chalmers says convincing but something of a Pyrrhic victory. (shrink)

[written in 2005/2006 while I was a graduate student at CUNY. This version was awarded The Southwestern Philosophical Society Presidential Prize for an outstanding paper by a graduate student or recent PhD and was subsequently published in Southwest Philosophy Review] The idea that there is something that it is like to have a thought is gaining acceptance in the philosophical community and has been argued for recently by several philosophers. Now, within this camp there is a debate about which component (...) of the, say, the belief, is qualitative? Is the qualitative component part of the content of the belief, or part of the mental attitude that we take towards the content? Some argue that the qualitative character is had by the content of the thought; others argue that it belongs to the attitude type itself. I examine the two answers and argue that the quality of thought is best understood as taking a qualitative mental attitude towards some representational content. Each propositional attitude is distinguished by a unique quality and it is having that quality with respect to the content that makes it a belief, fear (etc.) that p. (shrink)

The papers in this special issue are all descended from papers presented at the second Online Consciousness Conference. I founded the Online Consciousness Conference at Consciousness Online (http:// consciousnessonline. wordpress. com) in 2008 mostly because no one else would. Being inspired by the Online Philosophy Conference, I mentioned to several people that it would be great if we had something like that in Consciousness Studies. People I talked to were very enthusiastic but no one seemed like they wanted to initiate (...) the process. I figured I would give it a shot and have been pleasantly surprised by the results. Papers from the first conference were published in a special issue of the Journal of Consciousness Studies, papers from the second are in this special issue, and papers from the third conference (2011) are due to come out as a book in Springer’s series Studies in Brain and Mind. As I write this I am planning the fourth conference for February 2012. There is no way I could have known back in 2008 how well the conference would be received but I am grateful for that reception.

While it seems to be evident that the vision of the eternal return of the same is the solution to the riddle mentioned in "On the vision and the riddle," exactly what constitutes the riddle is anything but clear. Li ke all good riddles the solution demands a paradigm shift. Nietzsche's riddle is solved by a radical rethinking of the concept of time, from a straight line to a circle. I give a detailed account of how Nietzsche's riddle is formulated (...) in such a way tha t the eternal return of the same is the only possible solution. (shrink)

Written in 2002/2003 while I was a graduate student at the University of Connecticut and ultimately submitted as part of my qualifying exam for the Master Degree in philosophy. I argue that the causal relation is observable even if the necessity of the connection is not. This version (the only one that remains) was prepared for presentation at the New Jersey Regional Philosophy Association.

[written in 2002/2003 while I was a graduate student at the University of Connecticut and ultimately submitted as part of my qualifying exam for the Masters of Philosophy] The question I am interested in revolves around Kant’s notion of the unity of experience. My central claim will be that, apart from the unity of experiencings and the unity of individual substances, there is a third unity: the unity of Experience. I will argue that this third unity can be conceived of (...) as a sort of ‘experiential space’ with the Aesthetic and Categories as dimensions. I call this ‘Euclidean Experience’ to emphasize the idea that individual experiencings have a ‘location’ within this framework much like individual objects have a location in space and time. The first sort of unity, that of experiences (or ‘experiencings’ as I will call them) is not enough. In order to have self-consciousness (ascribed atomic experiencings) there must be a consciousness in which the experiencings ‘take place’ just as in order for there to be objects there must be space in which they are located. With such a notion of experience in hand I argue that it can be used to bring together the solipsistic and non-solipsistic strands in Kant’s thinking. The resulting position I call ‘Polysolipsism.’.

David Rosenthal is a well-known defender of a particular kind of theory of consciousness known as the higher-order thought theory (HOTT). Higher-order theories are united by what Rosenthal calls the Transitivity Principle (TP), which states that a mental state is conscious iff one is conscious of oneself, in some suitable way, as being in that mental state. Since there are various ways to implement TP and HOTT commits one to the view that any mental state could occur unconsciously it seems (...) to predict that a mental state’s being conscious doesn’t have any significant function to perform. An unconscious mental state, according to the theory, has most of its causal connections already, as evidenced by priming studies, subliminal perception, and other empirical findings. Given this, one early objection to HOTT was to emphasize this consequence of the theory. Since consciousness does have a function any theory which predicts that it doesn’t must be suspect. Rosenthal’s primary goal in this paper is to defend HOTT against this objection. In fact he argues that if we could establish that consciousness has no function independently of HOTT we would then have an analogous argument for it: Since consciousness doesn’t have any significant function any theory which predicts that it doesn’t fares be.

As its title suggests, this anthology is a collection of papers presented at a conference on feelings and emotions held in Amsterdam in 2001. One of the symposium’s main goals was to draw some of the most prominent researchers in emotion research together and provide a multi-disciplinary ‘snap shot’ of the state of the art at the turn of the century. In that respect it is truly a cognitive science success story. There are articles from a wide range of fields, (...) encompassing, e.g., philosophy, neuroscience, anthropology, sociology, and psychology. Another goal was to emulate a series of conferences of the same name that had taken place in the early parts of the 20th Century. Included in the book are the title pages of these other conferences, which put the symposium in a nice historical context. The conference seems to have met both goals. It does, for instance, offer a vital snap shot of the state of emotions research at the turn of the century, though this does not mean that it is best suited for the annals of history. This volume will provide anyone interested in the cognitive science of the emotions a clear indication of where the field has come from, and insight into where it will be going. (shrink)

This volume is product of the third online consciousness conference, held at http:// consciousnessonline. com in February and March 2011. Chapters range over epistemological issues in the science and philosophy of perception, what neuroscience can do to help us solve philosophical issues in the philosophy of mind, what the true nature of black and white vision, pain, auditory, olfactory, or multi-modal experiences are, to higher-order theories of consciousness, synesthesia, among others. Each chapter includes a target article, commentaries, and in most (...) cases, a final response from the author. Though wide-ranging all of the papers aim to understand consciousness both from the inside, as we experience it, and from the outside as we encounter it in our science. (shrink)

Adviser: Professor Stefan Baumrin In the first chapter I introduce the distinction between metaethics and normative ethics and argue that metaethics, properly conceived, is a part of cognitive science. For example, the debate between rationalism and sentimentalism can be informed by recent empirical work in psychology and the neurosciences. In the second chapter I argue that the traditional view that one’s theory of semantics determines what one’s theory of justification must be is mistaken. Though it has been the case that (...) there are ‘typical’ combinations of semantic and justificational theories this is by no means forced on one. In the third chapter I examine two current kinds of expressivism; that of Blackburn and Copp. Each gives us an example of different combinations of semantic and justificatory theory. In Blackburn’s case he combines a use theory of meaning with a classic emotivist theory of justification, In Copp’s case it is a neo-Gricean philosophy of language with a realist’s theory of justification. I find both of these wanting as they ultimately collapse into relativistic subjectivism. In the fourth and fifth chapter I turn to developing Emotive Realism. The basic idea behind this view is that when someone says ‘x is wrong/right’ that person has (a) expressed a moral emotion about x and at the same time (b) expressed the belief that the emotion in (a) is the correct one to have. The belief expressed in (b) will be true or false depending on one’s theory of justification. In the fourth chapter I argue that we need separate semantic theories for thoughts and sentences. In the fifth chapter I fill in the details of Emotive Realism as I see it. (shrink)
