The thesis proposes, defends, and applies a new model of inter-theoretic reduction, called "Neo-Nagelian" reduction. There are numerous accounts of inter-theoretic reduction in the philosophy of science literature but the most well-known and widely-discussed is the Nagelian one. In the thesis I identify various kinds of problems which the Nagelian model faces. Whilst some of these can be resolved, pressing ones remain. In lieu of the Nagelian model, other models of inter-theoretic reduction have been proposed, chief amongst which are so-called (...) "New Wave" models. I show these to be no more adequate than the original Nagelian model. I propose a new model of inter-theoretic reduction, Neo-Nagelian reduction. This model is structurally similar to the Nagelian one, but differs in substantive ways. In particular I argue that it avoids the problems pertaining to both the Nagelian and New Wave models. Multiple realizability looms large in discussions about reduction: it is claimed that multiply realizable properties frustrate the reduction of one theory to another in various ways. I consider these arguments and show that they do not undermine the Neo-Nagelian of reduction of one theory to another. Finally, I apply the model to statistical mechanics. Statistical mechanics is taken to be a reductionist enterprise: one of the aims of statistical mechanics is to reduce thermodynamics. Without an adequate model of inter-theoretic reduction one cannot assess whether it succeeds; I use the Neo-Nagelian model to critically discuss whether it does. Specifically, I consider two very recent derivations of the Second Law of thermodynamics, one from Boltzmannian classical statistical mechanics and another from quantum statistical mechanics. I argue that they are partially successful, and that each makes for a promising line of future research. (shrink)

The guiding question for this essay is: who is the learner? The aim is to examine and criticize one answer to this question, sometimes referred to as the theory of the learning brain, which suggests that the explanation of human learning can be reduced to the transmitting and storing of information in the brain’s formal and representational architecture, i.e., that the brain is the learner. This essay will argue that this answer is misleading, because it cannot account for the way (...) people strive to learn in an attempt to lead a good life as it misrepresents the intentional life of the mind, which results in its counting ourselves out of the picture when it attempts to provide a scientific theory of the learning process. To criticize the theory of the learning brain, this essay will investigate its philosophical foundation, a theory of mind called cognitivism, which is the basis for the cognitive sciences. Cognitivism is itself built on three main tenets: mentalism, the mind-brain identity theory and the computer analogy. Each of these tenets will be criticized in turn, before the essay turns to criticize the theory of the learning brain itself. The focus of this essay is, in other words, mainly negative. The hope is that this criticism will lay the groundwork for an alternative view of mind, one that is better equipped to give meaningful answers to the important questions we have about what it means to learn, i.e., what we learn, how we do it and why. This alternative will emphasize the holistic and intentional character of the human mind, and consider the learning process as an intentional activity performed, not by isolated brains, but by people with minds that are extended, embodied, enacted and embedded in a sociocultural and physical context.

In this paper, we develop a mathematical model of awareness based on the idea of plurality. Instead of positing a singular principle, telos, or essence as noumenon, we model it as plurality accessible through multiple forms of awareness (“n-awareness”). In contrast to many other approaches, our model is committed to pluralist thinking. The noumenon is plural, and reality is neither reducible nor irreducible. Nothing dies out in meaning making. We begin by mathematizing the concept of awareness by appealing to the (...) mathematical formalism of higher category theory. The beauty of higher category theory lies in its universality. Pluralism is categorical. In particular, we model awareness using the theories of derived categories and (infinity, 1)-topoi which will give rise to our meta-language. We then posit a “grammar” (“n-declension”) which could express n-awareness, accompanied by a new temporal ontology (“n-time”). Our framework allows us to revisit old problems in the philosophy of time: how is change possible and what do we mean by simultaneity and coincidence? Another question which could be re-conceptualized in our model is one of soteriology related to this pluralism: what is a self in this context? A new model of “personal identity over time” is thus introduced. (shrink)

The present paper offers a contrast between the philosophical ideas of Stoicism and contemporary ideas in philosophy of the mind, to understand the nature of intentionality and phenomenal experience as a fundamental element in a theory of "happiness". The metaphysical foundation that I fallow is based on a physicalist approach in non-reductive terms, from a perspective derived from a phenomenal-intentionality program, that is, the idea that intentionality depends on its phenomenal characteristics, in this way, an analysis of popular psychology and (...) propositional attitudes as a contemporary basis for reinterpreting metaphysics and stoic epistemology in particular from the ideas exposed by Epictetus is possible. It is concluded that an interpretation more in line with the phenomenal characteristics of intentionality can provide a solid base to understand the nature of representation and the change in the narrative suggested by Epictetus rather than the representational theories such as those advocated by Michael Tye as the path to understand happiness.

This is a thesis about interdisciplinarity, scientific integration, and problem solving in sustainability science. Sustainability science is an emerging and highly interdisciplinary field that seeks to integrate vastly differentiated bodies of knowledge in addressing the challenge of transitioning contemporary societies towards sustainability. Interdisciplinarity is paramount. Interdisciplinarity in general, and in the context of sustainability science in particular, has often been associated with solving particular problems and problem solving is one important theme in this thesis. A central idea that is developed (...) is that of problem-feeding. Sometimes problems arise within one discipline that can only be solved with the help of another. This concept, that has predecessors in e.g. the work of Lindley Darden and Nancy Maull, is explored considerably. It is argued that in interdisciplinary contexts—such as sustainability science—where collaboration is sought it is important to maintain cross-boundary problem stability. That is to say, as the problem is transferred from one discipline to another transformations will often be necessary. These transformations then, need to be acceptable to all involved parties to maintain an active interdisciplinary connection. Another topic that is discussed both in the introductory essay and some of the papers included is that of scientific imperialism. Scientific imperialism—the infringement of one discipline upon the domain of another—is here suggested to be primarily a threat to in-terdisciplinary collaborations. A distinction is introduced between imperialist failures of expansionism and failures of replacement. These are labelled type-I and type-II imperialism respectively. Particular attention is devoted to the latter form. Type-II imperialism concerns cases where imperialist infringements fail as the imperial- izing framework replaces viable, or compatible alternatives. Such an error of replacement does, importantly, not imply that the framework or theory should be disregarded completely. This type of imperialist error can both be quite subtle, and damaging. For one, if one directs the attention to specific contexts knowledge is actually lost in the process. This is particularly serious in fields such as sustainability science that are, to such an large extent, aimed at influencing concrete policy. Finally, interdisciplinarity is difficult to achieve and in many cases represents a grand challenge in itself. There are however many different ways in which interdisciplinarity may be accomplished and different forms are suitable in different contexts. In a field such as sustainability science where complexity is such a prevalent feature, an inclusive, pluralist, approach is likely to be appropriate. (shrink)

The term “consciousness” is very often, though not always, interchangeable with the term “awareness,” which is more colloquial to many ears. We say things like “are you aware that ...” often. Sometimes we say “have you noticed that ... ?” to express similar thoughts, and this indicates a close connection between consciousness (awareness) and attention (noticing), which we will come back to later in this chapter. Ned Block, one of the key figures in this area, provides a useful characterization of (...) what he calls “phenomenal consciousness.” For him, phenomenal consciousness is experience. Experience covers perceptions, e.g., when we see, hear, touch, smell, and taste, we typically have experiences, such as seeing colors and smelling odors. It also covers bodily awareness, e.g., we typically have experiences of our own bodily temperature and positions of limbs. Consciousness is primarily about this experiential aspect of our mental lives. (shrink)

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. (shrink)

Recently, several philosophers have argued that nonreductive physicalism is a false, unstable, and incoherent position. I argue that the position these critics are attacking is a straw one. To help explain why let us distinguish three issues about which nonreductive physicalists might plausibly be thought to have an opinion: ontological considerations about the types of things that exist at a world, issues involving the existence and nature of any dependency relationships between the types of things that exist at a world, (...) and epistemological questions regarding the best way to describe, explain, or characterize the types of things that exist at a world. I argue that reductive and nonreductive physicalists essentially agree with respect to the first two issues, but disagree with respect to the last issue. Nonreductive physicalists advocate a position that is ontologically or metaphysically reductive, but epistemologically or representationally nonreductive. Although this position could prove false on empirical grounds, it is neither unstable nor incoherent. (shrink)

Multiple Realizability (MR) must still be regarded as one of the principal arguments against type reductionist accounts of higher-order properties and their special laws. Against this I argue that there is no unique MR but rather a multitude of MR categories. In a slogan: MR is itself “multi-realized”. If this is true then we cannot expect one unique reductionist strategy against MR as an anti-reductionist argument. The main task is rather to develop a taxonomy of the wide variety of MR (...) cases and to sketch possible reductionist answers for each class of cases. The paper outlines some first steps in this direction. (shrink)

A consideration of the benefits of taking physicalism to be necessarily true if true, against the standard view that physicalism is at best contingently true.

In mental action there is no motor output to be controlled and no sensory input vector that could be manipulated by bodily movement. It is therefore unclear whether this specific target phenomenon can be accommodated under the predictive processing framework at all, or if the concept of “active inference” can be adapted to this highly relevant explanatory domain. This contribution puts the phenomenon of mental action into explicit focus by introducing a set of novel conceptual instruments and developing a first (...) positive model, concentrating on epistemic mental actions and epistemic self-control. Action initiation is a functionally adequate form of self-deception; mental actions are a specific form of predictive control of effective connectivity, accompanied and possibly even functionally mediated by a conscious “epistemic agent model”. The overall process is aimed at increasing the epistemic value of pre-existing states in the conscious self-model, without causally looping through sensory sheets or using the non-neural body as an instrument for active inference.

This paper is an analysis of scientific types – the categories of a scientific taxonomy. I argue that the philosophical view about mental types stands in contrast to the real nature of scientific types, which is in turn responsible for the mind-body problem. Since the view on the relation between psychology and neurology was broadened to the status about special sciences in general, my argument can also be applied to the general special science discussion. My picture of types being the (...) result of categorizing tokens with respect to their micro structure is used to show how scientific practice makes multiple realizability implausible. (shrink)

The problem of mental causation is discussed by taking into account some recent developments in the philosophy of science. The problem is viewed from the perspective of the new interventionist theory of causation developed by Woodward. The import of the idea that causal claims involve contrastive classes in mental causation is also discussed. It is argued that mental causation is much less a problem than it has appeared to be.

Some people believe that there is an “explanatory gap” between the facts of physics and certain other facts about the world—for example, facts about consciousness. The gap is presented as a challenge to any thoroughgoing naturalism or physicalism. We believe that advocates of the explanatory gap have some reasonable expectations that cannot be merely dismissed. We also believe that naturalistic thinkers have the resources to close the explanatory gap, but that they have not adequately explained how and why these resources (...) work. In this paper we isolate the legitimate explanatory demands in the gap reasoning, as it is defended by Chalmers and Jackson . We then argue that these demands can be met. Our solution involves a novel proposal for understanding the relationship between theories, explanations, and scientific identities. (shrink)

En el texto se exponen las opiniones de Saul Kripke acerca del funcionalismo en la filosofía de la mente, que aún permanecen en gran parte sin publicarse, con base en la transcripción de una charla suya de 1984 sobre este tema, y se identifican algunas preguntas sin resolver.

Frank Jackson’s knowledge argument (KA) aims to prove, by means of a thought experiment concerning the hypothetical scientist Mary, that conscious experiences have non-physical properties, called qualia. Mary has complete scientific knowledge of colours and colour vision without having had any colour experience. The central intuition in the KA is that, by seeing colours, Mary will learn what it is like to have colour experiences. Therefore, her scientific knowledge is incomplete, and conscious experiences have qualia. In this paper I consider (...) an objection to the KA raised by Daniel Dennett. He maintains that the KA is vitiated by Jackson’s account of Mary’s scientific knowledge. While endorsing this criticism, I will defend the plausibility and relevance of the type of strategy involved in the KA by offering an account of Mary’s scientific knowledge. This account involves formulating a reasonable and not immediately false version of the physicalist thesis with regard to colour experiences. Whether this version of the KA is successful against this type of physicalism is not investigated here. (shrink)

Recent advancements in the brain sciences have enabled researchers to determine, with increasing accuracy, patterns and locations of neural activation associated with various psychological functions. These techniques have revived a longstanding debate regarding the relation between the mind and the brain: while many authors now claim that neuroscientific data can be used to advance our theories of higher cognition, others defend the so-called `autonomy' of psychology. Settling this significant question requires understanding the nature of the bridge laws used at the (...) psycho-neural interface. While these laws have been the topic of extensive discussion, such debates have mostly focused on a particular type of link: reductive laws. Reductive laws are problematic: they face notorious philosophical objections and they are too scarce to substantiate current research at the interface of psychology and neuroscience. The aim of this article is to provide a systematic analysis of a different kind of bridge laws--associative laws--which play a central, albeit often overlooked, role in scientific practice. (shrink)

What is the relationship between pain and the body? I claim that pain is best explained as a type of personal experience and the bodily response during pain is best explained in terms of a type of mechanical neurophysiologic operation. I apply the radical philosophy of identity theory from philosophy of mind to the relationship between the personal experience of pain and specific neurophysiologic mechanism and argue that the relationship between them is best explained as one of type identity. Specifically, (...) pain is a specific type of personal experience identical to a specific type of allostatic stress response comprised of interdependent nervous, endocrine and immune mechanical operations.

Jackendoff defends a mentalist approach to semantics that investigates conceptual structures in the mind/brain and their interfaces with other structures, including specifically linguistic structures responsible for syntactic and phonological competence. He contrasts this approach with one that seeks to characterize the intentional relations between expressions and objects in the world. The latter, he argues, cannot be reconciled with mentalism. He objects in particular that intentionality cannot be naturalized and that the relevant notion of object is suspect. I critically discuss these (...) objections, arguing in part that Jackendoff’s position rests on questionable philosophical assumptions. (shrink)

The Philosophy of Information is a new area of research at the intersection of philosophy and computer science [4]. It concerns (a) the critical investigation of the conceptual nature and basic principles of information, including its dynamics (especially computation), utilization (especially computer ethics) and sciences; and (b) the elaboration and application of computational and information-theoretic methodologies to philosophical problems. Past work by members of our group has concentrated on (a), and in this paper we explore (b). In a nutshell, we (...) ask what computer science can do for philosophy, rather than what the latter can do for the former. -/- . (shrink)

In his Introduction to Contemporary Metaethics, Alex Miller considered a defence that might be made on behalf of the moral non-reductive naturalist in response to Gilbert Harman’s explanatory objection, a response that uses Frank Jackson’s and Philip Pettit’s account of ‘program explanation.’ However, Miller went on to argue that program explanation fails to successfully defend the moral non-reductive naturalist against Harman’s objection. Recently Paul Bloomfield and Mark Nelson have argued against Miller that program explanation does in fact successfully defend the (...) moral non-reductive naturalist, because the only full explanation of why the relevant counterfactual, discussed in this thesis, is true requires the use of program explanation. Following Miller, I argue that the fact that counterfactuals are context sensitive undermines the argument developed by Nelson, and I also attempt to undermine Bloomfield’s recent defence of Nelson. Contrary to Bloomfield and Nelson, program explanation is not required in order to explain why the relevant counterfactual is true, so that Harman’s explanatory objection is left intact. (shrink)

This dissertation explores issues in the philosophy of psychology and metaphysics through the lens of the emotion of disgust, and its corresponding property, disgustingness. The first chapter organizes an extremely large body of data about disgust, imposes two constraints any theory must meet, and offers a cognitive model of the mechanisms underlying the emotion. The second chapter explores the evolution of disgust, and argues for the Entanglement thesis: this uniquely human emotion was formed when two formerly distinct mechanisms, one dedicated (...) to monitoring food intake and protecting against poisons, the other dedicated to protecting against parasitic infection, where driven together until they became functionally integrated. The third chapter explores the sorts of acquisition mechanisms that could give rise to the patterns of individual and cultural level variation we find with disgust elicitors. It argues for the Empathic Acquisition thesis, which holds that one important route for the social acquisition and transmission of disgust elicitors is linked to empathic recognition of facial expressions of the emotion. The fourth chapter builds on the Entanglement thesis, and embeds the emotion of disgust in gene-culture coevolutionary theory and the tribal instincts hypothesis. The Co-opt thesis is defended, which maintains that disgust was co-opted to play an important role in our moral psychology, particularly in our cognition of social norms and ethnic boundary markers. In doing so, however, it brings to bear many features initially linked to poisons and parasites. This explains the puzzling and troublesome character of moral judgments linked to disgust. After shifting gears from psychology to metaphysics, the fifth chapter recasts the Humean tradition of projectivism in the terminology of cognitive science. Using examples such as disgust, I argue that a psychologized projectivism is able to make sense of the idea that some properties are projected onto the world, rather than found there to begin with. The final chapter criticizes three other accounts of the property of disgustingness, two inspired by functionalism in the philosophy of color, one inspired by fittingness accounts in metaethics. I argue that none provide nearly as satisfactory account of the property as the psychologized projectivism articulated previously. (shrink)

Quantum gravity is understood as a theory that, in some sense, unifies general relativity (GR) and quantum theory, and is supposed to replace GR at extremely small distances (high-energies). It may be that quantum gravity represents the breakdown of spacetime geometry described by GR. The relationship between quantum gravity and spacetime has been deemed ``emergence'', and the aim of this thesis is to investigate and explicate this relation. After finding traditional philosophical accounts of emergence to be inappropriate, I develop a (...) new conception of emergence by considering physical case studies including condensed matter physics, hydrodynamics, critical phenomena and quantum field theory understood as effective field theory. This new conception of emergence is unconcerned with the ideas of reduction and derivation (i.e. it holds that we may have emergence with reduction or without it). Instead, a low-energy theory (or model) is understood as emergent from a high-energy theory if it is novel and autonomous compared to the high-energy theory, and the low-energy physics is dependent in a particular, minimal sense on the high-energy physics (this dependence is revealed by the techniques of effective field theory and the renormalisation group). While novelty is construed in a broad sense, the autonomy comes essentially from the underdetermination of the high-energy theory by the low-energy theory, which reflects the minimal way in which the emergent, low-energy theory depends on the high-energy one. It results from the scaling behaviour of the theories and the limiting relations between them, and is demonstrated by the renormalisation group and effective field theory techniques, the idea of universality, and the phenomenon of symmetry-breaking. These ideas are important in exploring the relationship between quantum gravity and GR, where GR is understood as an effective, low-energy theory of quantum gravity. Without experimental data or a theory of quantum gravity, we rely on principles and techniques from other areas of physics to guide the way. As well as considering the idea of emergence appropriate to treating GR as an effective field theory, I investigate the emergence of spacetime (and other aspects of GR) in several concrete approaches to quantum gravity, including examples of the condensed matter approaches, the ``discrete approaches'' (causal set theory, causal dynamical triangulations, quantum causal histories and quantum graphity) and loop quantum gravity.

In this thesis, I argue that physicalism should be understood to be the view that mental properties are realized by physical properties. In doing this, I explore what the realization relation might be. Since realization is the relation that should help us formulate physicalism, I suggest that the theoretical role of realization consists in explaining some of the things that physicalists wish to explain. These are: How are mental properties metaphysically necessitated by physical properties? How are mental properties causally efficacious? (...) A theory of realization should provide resources for answering these questions. Having identified the theoretical role of realization, I discuss several theories of realization, but then focus on the subset view of realization. According to the subset view, a property P realizes a property Q if and only if the causal powers of Q are a proper subset of the causal powers of P. I argue that the realization relation as it is formulated by the subset view is a promising candidate to play the theoretical role that I want realization to play. I then investigate how this theoretical role is occupied. In doing so, I provide a general metaphysical framework that the defenders of the subset view can appeal to. This framework specifies in what ways properties are related to their causal powers. Discussing some problems that the subset view faces, I propose my own version of the subset view. I argue that a property P realizes a property Q if and only if the causal powers of Q are a proper subset of the causal powers of P, and P is more fundamental than Q. Thanks to the requirement that a realized property is less fundamental than its realizers, two things that the original version of the subset view cannot explain are guaranteed: first, fundamental properties are not realized; second, arbitrary conjunctions of properties do not realize their conjuncts. By showing how a theory of realization can help us explain some of the things that physicalists typically wish to explain, I also show that a non-reductive variety of physicalism does not face the problems that it is commonly thought to face.

I examine the debate between reductive and non-reductive physicalists, and conclude that if we are to be physicalists, then we should be reductive physicalists. I assess how both reductionists and non-reductionists try to solve the mind-body problem and the problem of mental causation. I focus on the problem of mental causation as it is supposed to be faced by non-reductionism: the so-called overdetermination problem. I argue that the traditional articulation of that problem is significantly flawed, and I show how to (...) articulate it properly: what I call the ‘super-overdetermination problem’. In doing so, I demonstrate that the problem of mental causation faced by non-reductionism is in fact a special case of the mind-body problem, as faced by non-reductionism, and that the former can’t be solved independently of the latter. I then assess the prospects for a particular family of non-reductive views that I call immanentism, and show that they fail to solve the super-overdetermination problem. Finally, I put forward two arguments to support the conclusion that physicalism entails reductionism. Both arguments establish, via distinct reasoning, the proposition that mental property instances are identical to physical property instances; and then each argument employs the inference, which I also defend, that if mental instances are physical instances, then mental properties are physical properties; hence, reductionism follows.

I believe that there are only a select few topics, which arouse a similar level of interest and curiosity among academics and laymen alike, as does the study of mind and brain. Although mind and brain have been capturing the attention of philosophers for centuries, it is the "scientific investigation" of age old philosophical queries by socalled cognitive scientists, which is distinctive of the developments of the last few decades and which, in times to come, may well be considered the (...) hallmark of the study of mind in the 20th and early 21st centuries. In the past, advances in the natural sciences underlay or boosted a plethora of developments in the technological, economic and political spheres that not only improved the standard of living and prolonged the average life span for a vast number of people, but also fuelled hopes that a new and improved understanding of the nature of man was also within reach. Despite all the benefits mankind derived from scientific and technological progress past and present, the success of the natural sciences also helped spread and foster a virulent and nowadays quasi-ubiquitous and unquestioned believe in the omnipotence of science and technology. In the context of the study of mind, in particular, it fostered the widespread conception that in order for an investigation leading to insight and understanding a "scientific" approach is a sine qua non. This thesis highlights the danger of such an approach. By investigating the framework of explanation adopted by cognitive scientists, the cognitive view, and by examining its inherent conceptions of mind and thought, it will be shown that the scientific, or rather scientistic, approach inherent in the views depicted above is highly questionable, and in the case of the study of mind and brain, does not further insight and understanding, but rather prevents it. In the 20th century, Ludwig Wittgenstein has been one of the few philosophers who recognized the fallaciousness of these ideas and who opposed the inherent scientism. His later philosophy, which provides the philosophical mise en scène for the following investigations, provides a much-needed antidote against the misconceptions common among cognitive scientists today. Although, many of the shortcomings of the ideas and views of cognitive scientists have, with a certain regularity, been discussed by philosophers working in the tradition of the later Wittgenstein their criticisms, more often than not, fell on deaf ears. I believe that one of the main reasons underlying the imperviousness of the community of cognitive scientists to the criticism of the kind of analytic philosophy inspired by the later Wittgenstein, is that it mainly focused on select misconceptions inherent in the cognitive view, but regularly failed to point out their place in the overall framework of thought for cognitive scientists. As a result, it was easy to dismiss these criticisms with excuses of the sort "but that does not bear any direct relevance to the work I do...". For this reason, this thesis aimed to portray and examine the cognitive view in its entirety, i.e. to depict the intricate interconnections existing between the premises that provide the foundation of the cognitive view, and to point out their disastrous consequences for our understanding not only of a select view aspects of mental phenomena, but to our understanding of the mind in its entirety. In order to provide such a "big picture", and to describe the numerous often very subtle interconnections between the various ideas making up the cognitive view in all their breadth and depth, a lot of well-trodden ground had to be revisited and reviewed. Thus, Anthony Kenny's and Peter Hackers' discussions of the mereological fallacy will provide the "base camp" from which we will visit less familiar aspects of the cognitive view via novel routes on our way to the peak of this "philosophical mountain". Where required, my indebtedness to the works of these philosophers will be highlighted throughout the text. (shrink)

Anti-reductionists hold that special science explanations of some phenomena are objectively better than physical explanations of those phenomena. Prominent defenses of this claim appeal to the multiple realizability of special science properties. I argue that special science explanations can be shown to be better, in one respect, than physical explanations in a way that does not depend on multiple realizability. Namely, I discuss a way in which a special science explanation may be more abstract than a competing physical explanation, even (...) if it is not multiply realizable, and I argue that this kind of abstraction can be used to support the idea that that special science explanation omits explanatorily irrelevant detail.

Defenders of the Knowledge Argument contend that physicalism is false because knowing all the physical truths is not sufficient to know all the truths about the world. In particular, proponents of the Knowledge Argument claim that physicalism is false because the truths about the character of conscious experience are not knowable from the complete set of physical truths. This dissertation is a defense of the Knowledge Argument. Chapter one characterizes what physicalism is and provides support for the claim that if (...) knowing all the physical truths is not sufficient to know all the truths about the world, then physicalism is false. In chapter two, I defend the claim that knowing all the physical truths is not sufficient for knowing all the truths about the world. In addition to mounting a prima facie case for the knowledge intuition, I present and defend an epistemology grounded in direct acquaintance to provide a more substantive argument to accept it. Chapters three through five address the physicalist objections to the Knowledge Argument. The first set of objections advocates that knowing all the physical truths is, in fact, sufficient for knowing all the truths about the world. The next set of objections admits that there is some sense in which knowing all the physical truths is not sufficient for knowing all the truths about the world. However, these objections maintain that the kind of knowledge that is absent from the complete set of physical truths is know-how or knowledge by acquaintance, and not factual or propositional knowledge. The final set of objections maintain that the kind of propositional knowledge that is left out of the complete set of physical truths is compatible with physicalism. My response to these objections is part of advancing my prima facie case for the Knowledge Argument. The final chapter addresses a structural question that pertains to the Knowledge Argument. Some philosophers have maintained that the structure of the Knowledge Argument invites a kind of self-refutation of any systematic account of reality. The concern is that the Knowledge Argument proves too much, and that the dualist who uses the argument to refute physicalism risks the argument defeating his own position. I will argue that the Knowledge Argument does not refute dualism. (shrink)

In this paper, we propose a mathematical model of subjective experience in terms of classes of hierarchical geometries of representations (“n-awareness”). We first outline a general framework by recalling concepts from higher category theory, homotopy theory, and the theory of (infinity,1)-topoi. We then state three conjectures that enrich this framework. We first propose that the (infinity,1)-category of a geometric structure known as perfectoid diamond is an (infinity,1)-topos. In order to construct a topology on the (infinity,1)-category of diamonds we then propose (...) that topological localization, in the sense of Grothendieck-Rezk-Lurie (infinity,1)-topoi, extends to the (infinity,1)-category of diamonds. We provide a small-scale model using triangulated categories. Finally, our meta-model takes the form of Efimov K-theory of the (infinity,1)-category of perfectoid diamonds, which illustrates structural equivalences between the category of diamonds and subjective experience (i.e.its privacy, self-containedness, and self-reflexivity). Based on this, we investigate implications of the model. We posit a grammar (“n-declension”) for a novel language to express n-awareness, accompanied by a new temporal scheme (“n-time”). Our framework allows us to revisit old problems in the philosophy of time: how is change possible and what do we mean by simultaneity and coincidence? We also examine the notion of “self” within our framework. A new model of personal identity is introduced which resembles a categorical version of the “bundle theory”: selves are not substances in which properties inhere but (weakly) persistent moduli spaces in the K-theory of perfectoid diamonds.

Peter Menzies has developed a novel version of the exclusion principle that he claims to be compatible with the possibility of mental causation. Menzies proposes to frame the exclusion principle in terms of a difference-making account of causation, understood in counterfactual terms. His new exclusion principle appears in two formulations: upwards exclusion — which is the familiar case in which a realizing event causally excludes the event that it realizes — and, more interestingly, downward exclusion, in which an event causally (...) excludes its realizer. This paper shows that one consequence of Menzies’s proposed solution to the problem of mental causation is a ubiquitous violation of the principle of closure — a fact that forces him into a trilemma to which we see no satisfactory response.
