This book appears as the eighth installment of the series Controversies, which is edited by Marcelo Dascal at Tel Aviv University. The series has as its stated goal publishing "studies in the theory of controversy,... studies in the history of controversy forms and their evolution, case studies of particular or current controversies,... and other controversy focused books". Senderowicz is a Kantian scholar, having also written The Coherence of Kant's Transcendental Idealism and several papers interpreting Kant. Both of these themes are evident in Controversies and the Metaphysics of Mind. The book offers a decidedly neo-Kantian interpretation of the role that controversies play in metaphysical theorizing and applies this interpretation to two recent debates in the metaphysics of mind. The first is the debate about physicalism and the second is the debate about personal identity. The issues that are addressed include the relation of metaphysics to science and whether or not metaphysics deals with a distinctive subject matter or uses a distinctive method. This puts the book amongst the growing number of works in metametaphysics.

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.

[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.

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.

As is well known, we can prove that everything that exists necessarily exists in S5. Perhaps as well known is Kripke’s two-part solution. First we forbid axioms with free variables and second we forbid the use of singular terms. One way to do the latter is via Nominal Description Theory (NDT): a name N is semantically equivalent to the description that mentions the name, e.g. ‘the-bearer-of-“N”’. But how do we reconcile NDT with the thesis of rigid designation? I argue that we need to distinguish a semantic theory that aims to give an account of thoughts (P-semantics) from one that aims to give an account of English sentence types (L-semantics). I then introduce frigidity as the claim that there are no L-semantic singular terms. The causal theory of reference is a P- semantic theory and together with NDT we can then formulate L-semantic descriptions that cap..

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.

Theories of consciousness can be separated into those that see it as cognitive in nature, or as an aspect of cognitive functioning, and those that see consciousness as importantly distinct from any kind of cognitive functioning. One version of the former kind of theory is the higher-order-thought theory of consciousness. This family of theories posits a fundamental role for cognitive states, higher-order thought-like intentional states, in the explanation of conscious experience. These states are higher-order in that they represent the subject herself as being in various world-directed first-order states and thus constitute a kind of cognitive access to one's own mental life. This distinctive cognitive access is postulated to account for what it is like for one to have a conscious experience. One important challenge to this approach is Block's case for phenomenological overflow (Block, 2007, 2011, 2012). The basic argument is that, overall, the balance of evidence favors the identification of phenomenal consciousness with first-order non-cognitive states rather than our cognitive access to those states. Emerging clearly from the ensuing debate is that Block's argument is meant to establish that phenomenology overflows working memory. This is important because, unlike other theories, the higher-order thought theory can allow that our conscious experience overflows working memory. In addition, it can account for the subjective impression that there is overflow even if there isn't.

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.

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.

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.
