The problem of multiple-computations discovered by Hilary Putnam presents a deep difficulty for functionalism (of all sorts, computational and causal). We describe in out- line why Putnam’s result, and likewise the more restricted result we call the Multiple- Computations Theorem, are in fact theorems of statistical mechanics. We show why the mere interaction of a computing system with its environment cannot single out a computation as the preferred one amongst the many computations implemented by the system. We explain why nonreductive (...) approaches to solving the multiple- computations problem, and in particular why computational externalism, are dualistic in the sense that they imply that nonphysical facts in the environment of a computing system single out the computation. We discuss certain attempts to dissolve Putnam’s unrestricted result by appealing to systems with certain kinds of input and output states as a special case of computational externalism, and show why this approach is not workable without collapsing to behaviorism. We conclude with some remarks about the nonphysical nature of mainstream approaches to both statistical mechanics and the quantum theory of measurement with respect to the singling out of partitions and observables.

I defend a how-possibly argument for Kantian (or Kant*-ian) transcendental idealism, drawing on concepts from David Chalmers, Nick Bostrom, and the cyberpunk subgenre of science fiction. If we are artificial intelligences living in a virtual reality instantiated on a giant computer, then the fundamental structure of reality might be very different than we suppose. Indeed, since computation does not require spatial properties, spatiality might not be a feature of things as they are in themselves but instead only the way that (...) things necessarily appear to us. It might seem unlikely that we are living in a virtual reality instantiated on a non-spatial computer. However, understanding this possibility can help us appreciate the merits of transcendental idealism in general, as well as transcendental idealism’s underappreciated skeptical consequences.

If you’re a materialist, you probably think that rabbits are conscious. And you ought to think that. After all, rabbits are a lot like us, biologically and neurophysiologically. If you’re a materialist, you probably also think that conscious experience would be present in a wide range of naturally-evolved alien beings behaviorally very similar to us even if they are physiologically very different. And you ought to think that. After all, to deny it seems insupportable Earthly chauvinism. But a materialist who (...) accepts consciousness in weirdly formed aliens ought also to accept consciousness in spatially distributed group entities. If she then also accepts rabbit consciousness, she ought to accept the possibility of consciousness even in rather dumb group entities. Finally, the United States would seem to be a rather dumb group entity of the relevant sort. If we set aside our morphological prejudices against spatially distributed group entities, we can see that the United States has all the types of properties that materialists tend to regard as characteristic of conscious beings.

Physicalism is the view, roughly, that everything is physical. This thesis is often characterized in terms of a particular supervenience thesis. Central to this thesis is the idea of physical duplication. I argue that the standard way of understanding physical duplication leads—along with other claims—to a sub-optimal consequence for the physicalist. I block this consequence by shifting to an alternative sense of physical duplication. I then argue that physicalism is best characterized by a supervenience thesis that employs both the new (...) sense of physical duplication and a new class of possible worlds. (shrink)

ABSTRACT This essay has three goals. The first is to introduce the notion of fundamentality and to argue that physicalism can usefully be conceived of as a thesis about fundamentality. The second is to argue for the advantages of fundamentality physicalism over modal formulations and that fundamentality physicalism is what many who endorse modal formulations of physicalism had in mind all along. Third, I describe what I take to be the main obstacle for a fundamentality-oriented formulation of physicalism: ‘the problem (...) of abstracta’, which asks how physical can accommodate phenomena such as mathematics and universals, and which modal formulations do not face. I canvas three solutions: the inapt for ground solution, the concrete restriction, and the contingency restriction. (shrink)

Naturalism is normally taken to be an ideology, censuring non-naturalistic alternatives. But as many critics have pointed out, this ideological stance looks internally incoherent, since it is not obviously endorsed by naturalistic methods. Naturalists who have addressed this problem universally foreswear the normative component of naturalism by, in effect, giving up science’s exclusive claim to legitimacy. This option makes naturalism into an empty expression of personal preference that can carry no weight in the philosophical or political spheres. In response to (...) this dilemma, I argue that on a popular (but largely unarticulated) construal of naturalism as a commitment to inference to the best explanation, methodological naturalism can be both normative and internally coherent.

Panpsychism, the view that consciousness is present everywhere at the fundamental level of reality, has established itself as an increasingly popular option in the philosophy of mind. Situated between substance dualism and reductive physicalism, panpsychism aims to capture the intuitions behind both, integrating consciousness into the physical world without explaining it in terms of purely physical facts. In this thesis, I offer a defence of panpsychism. -/- First, I examine influential arguments against physicalism, such as Thomas Nagel’s (1974, 1979) perspective-based (...) proposal, Frank Jackson’s (1982) knowledge argument, David Chalmers’ (1996, 2010) conceivability argument, as well as vagueness arguments (Antony 2006a; Tye 1996). I argue that none of them offers a knockdown case against physicalism, particularly because of the threat presented by the phenomenal concept strategy (Chalmers 2007; Papineau 2007a), though they suggest panpsychism as a promising alternative that avoids many common objections. -/- Second, I discuss independent arguments for panpsychism, including the Russellian monist view (Goff 2017; Russell 1927/1992), the intrinsic nature argument (Seager 2006; Strawson 2006), recent developments in the literature as presented by Hedda Hassel Mørch (2018, 2020) and Luca Dondoni (2022), Tye’s (2021b) representational panpsychism based on the vagueness argument, as well as cosmopsychism (Nagasawa & Wager 2016; Shani 2015) – an alternative to panpsychism that shares its aims whilst claiming to avoid its shortcomings. -/- Third, I address the most pressing objection to panpsychism: the combination problem or the question of how fundamental consciousness can combine to lead to complex consciousness (James 1890). Focusing especially on the subject-summing version of the combination problem or the issue of how small subjects can combine to form complex subjects, I go over various proposals for either solving or avoiding it, such as Philip Goff’s (2016) phenomenal bonding relation and William Seager’s (2010) combinatorial infusion proposal, arguing against both and agreeing at the end with Sam Coleman (2014), who advocates that subject-summing is demonstrably incoherent. -/- However, as I argue in the fourth and final chapter, the panpsychist still has an option that avoids the subject-summing problem, while also circumventing the objections faced by the alternative view of cosmopsychism. Inspired though not reliant on the philosophy of Gottfried Wilhelm Leibniz (1902/2005), I introduce what I call monadic panpsychism, the view that the phenomenal character of any given consciousness-bearing physical ultimate is determined by its relations to other such ultimates featuring in the relevant causal structure. -/- The theory consists of two key claims. The first is that phenomenal qualities are relational rather than intrinsic. This view has precedent in literature on the philosophy of mind, such as in Rudolf Carnap (1928), Gottlob Frege (1956), Moritz Schlick (1959), as well as more recently in David Hilbert and Mark Kalderon (2000) and Austen Clark (2000), though not in the context of panpsychism. -/- The second claim is that physical ultimates only possess a very basic form of consciousness necessary for experiencing as such. There are many ways to conceptualise this basic consciousness: non-relational or intrinsic, rudimentary and non-specific, a point of view without experiences, the minimal subject, a mere conduit for experience, phenomenal space, etc. Russellian panpsychists offer a more detailed proposal in which every physical ultimate has an appropriate associated type of experience. For example, all quarks have the same quark-type of experience, assuming for the sake of discussion that quarks are ultimates. Still, arguing for a more minimal notion, as I do, requires making less claims and should not be controversial to any panpsychist. -/- So, what follows from these two claims? I propose that the relational constitution of phenomenal qualities has its endpoint at the fundamental level rather than at the level of a combined complex or emergent subject. Put simply, physical ultimates guarantee the basic consciousness or the point of view that I occupy, while the relational structure constitutes my rich and full human experience. So to speak, relationally constituted phenomenal qualities ‘anchor’ themselves in physical ultimates. As long as these relations result in a phenomenally unified experience, which is an uncontroversial thesis, then no matter where that process reaches the end of its causal chain, it will necessarily be experienced from a subjective point of view. -/- Since only qualities but not subjects need to combine, my proposal avoids the subject-summing version of the combination problem, which is arguably an insurmountable challenge to other forms of panpsychism. Because of this, I conclude that my theory contributes to the field, serving as a good starting point for further developments of neither combinatory nor emergent panpsychism with regard to subjects.

The aim of this paper is to discuss a seemingly straightforward argument against physicalism which, despite being implicit in much of the philosophical debate about consciousness, has not received the attention it deserves (compared to other, better-known “epistemic”, “modal”, and “conceivability” arguments). This is the argument from the non-supervenience of the first-personal (and indexical) facts on the third-personal (and non-indexical) ones. This non-supervenience, together with the assumption that the physical facts (as conventionally understood) are third-personal, entails that some facts – (...) namely, first-personal, phenomenal ones – do not supervene on the physical facts. Unlike other arguments against physicalism, the first-personal argument, if successful, refutes not only physicalism but also other third-personal metaphysical pictures, including standard versions of dualism.

Type identity theory was dismissed in 1967 by many philosophers due to Hilary Putnam’s multiple realisability objection seeming fatal. This paper delves into a critique of type identity theory, thereby paving the way for introducing an alternative theory of mind: emergentism. The longstanding philosophical discourse around the mind has been dominated by the binary opposition of classical physicalist and dualist theories. However, the impact of scientific discovery on contemporary thought has sparked an increasing inclination towards reductive physicalist frameworks, with the (...) aim of aligning with the scientific method. Thus, contemporary thinkers have branched out to explore new physicalistic ideas. This paper examines the inherent challenges in all reductive physicalist theories, shedding light on their limitations and proposing potential solutions to overcome the obstacles. This analysis demonstrates that type identity theory, akin to its reductive counterparts, fails to accommodate for the irreducibility of consciousness. This is consciousness as characterised by Thomas Nagel’s “what is it likeness” of experience, which is inherently subjective. Instead, this paper contends that emergentism offers a compelling alternative despite being a physicalist theory. It posits consciousness as a higher-order phenomenon, one that transcends reduction to its constituent components. I argue that this attribute of emergentism makes it a promising theory in the ongoing quest for an understanding of the mind and consciousness. (shrink)

The aim of this work is to argue for the idea that processes and process-based entities are to be modelled as relational structures. Relational structures are genuine structures, namely entities not committed to the existence of basic objects. My argument moves from the analysis of Whitehead’s original insight about process-based entities that, despite some residual of substance metaphysics, has the merit of grounding the intrinsic dynamism of reality on the holistic and relational characters of process-based entities. The current model of (...) process ontology requires genuine emergence and this, in turn, requires organizations, i.e., emergence in organizations. Another view about processes rely on a structural specification of processes. I suggest that the two views can be made compatible by the help of a specific sort of structures, namely relational structures. The appeal to the mathematical theory of genuine structures, category theory, reveals the formal plausibility of this convergence. According to this formal approach, genuine structures are essentially dynamic entities for they are relational, namely, as well as organizations, they are not existentially committed to particulars.

The term ‘naturalism’ has no very precise meaning in contemporary philosophy. Its current usage derives from debates in America in the first half of the last century. The self-proclaimed ‘naturalists’ from that period included John Dewey, Ernest Nagel, Sidney Hook and Roy Wood Sellars. These philosophers aimed to ally philosophy more closely with science. They urged that reality is exhausted by nature, containing nothing ‘supernatural’, and that the scientific method should be used to investigate all areas of reality, including the (...) ‘human spirit’ (Krikorian 1944, Kim 2003).

This research will argue about which theory of mind between Searle’s and Dennett’s can better explain human consciousness. Initially, distinctions between dualism and materialism will be discussed ranging from substance dualism, property dualism, physicalism, and functionalism. In this part, the main issue that is tackled in various theories of mind is revealed. It is the missing connection between input stimulus (neuronal reactions) and behavioral disposition: consciousness. Then, the discussion will be more specific on Searle’s biological naturalism and Dennett’s multiple drafts (...) model as the two attempted to answer the issue. The differences between them will be highlighted and will be analyzed according to their relation to their roots: dualism and materialism. The two theories will be examined on how each answer the questions on consciousness. (shrink)

This chapter considers potential applications of grounding to the formulation of physicalism. I begin with an overview of competing conceptions of the physical and of physicalism. I then consider whether grounding physicalism overcomes well-known and seemingly fatal problems with supervenience physicalism. I conclude that while grounding physicalism improves upon supervenience physicalism in certain respects, it arguably falls victim to some of the same difficulties.

Humans' capacity to attain knowledge is central to Spinoza's philosophy because, in part, knowing things enables humans to deal properly with their affects. But it is not just any sort of knowledge that humans should attain. There are different types of knowledge, but only two of them–rational and intuitive knowledge–enable humans who attain them to know things clearly. Because rational knowledge attends to universals whereas intuitive knowledge attends to particulars, intuitive knowledge is better than rational knowledge at enabling humans to (...) deal with their affects. Most scholars recognize both the importance of knowledge to humans' dealing with their affects and the superiority of intuitive knowledge at enabling them to do this. But these points are particularly relevant to the affect that Spinoza calls "tristitia," which is usually translated as either "pain" or "sadness." I argue in this dissertation that attaining knowledge– especially intuitive knowledge–enables humans to deal properly with their experiences of pain. This ability that humans acquire by knowing things is what I call "active suffering." A person suffers passively when she merely reacts to her pain, in this way allowing an external force to control her. She suffers actively when she uses knowledge to respond to her pain, in this way being in control of herself. This knowledge she uses to deal actively with her pain bears a relation to Spinoza's theory of freedom, since it entails a realization that all events (such as a person's experience of pain) happen necessarily and that embracing this necessity is the same as being free.

This dissertation is a contribution to the philosophy of language. Its central question is: In virtue of which facts do linguistic expressions mean what they do? E.g. why does “apple” mean apple in English? The question receives a systematic answer; in short: Linguistic expressions mean what they do because among their users, there are linguistic conventions and social norms to use and understand them in certain ways. The answer is clarified and defended as a central thesis. For in this form, (...) it is at best a slogan: What is meaning? What is it to use and understand expressions? What are conventions and social norms anyway? How does the use and understanding determine meaning? The goal of the dissertation consists in answering these questions. (shrink)

Panpsychism is the view that every concrete and unified thing has some form of phenomenal consciousness or experience. It is an age-old doctrine, which, to the surprise of many, has recently taken on new life. In philosophy of mind, it has been put forth as a simple and radical solution to the mind–body problem (Chalmers 1996, 2003;Strawson 2006; Nagel 1979, 2012). In metaphysics and philosophy of science, it has been put forth as a solution to the problem of accounting for (...) the intrinsic nature of the physical itself (Strawson 2006, Seager 2006). In this thesis, I show that panpsychism can also be defended on the basis of an argument from our (arguable) acquaintance with the nature of causation in agency. This argument has made frequent appearances throughout the history of philosophy, with philosophers such as Leibniz, Schopenhauer and James, and I construct and defend an updated version of it. Furthermore, I offer a solution to the combination problem: how can complex (human and animal-type) consciousness result from simple (fundamental particle-type) consciousness? This is generally regarded as the most serious problem facing contemporary panpsychism. I propose that mental combination can be construed as kind causal process culminating in a fusion, and show how this avoids the main difficulties with accounting for mental combination. (shrink)

The thesis is about Multiple Realization. Multiple realization is roughly the idea of a higher level property being multiply realized by different lower level physical properties. Philosophers usually argue that if a property is multiply realized, it is not reducible to its realizers. Mobilized as such, multiple realization plays a central role in what is usually called Non-Reductive Physicalism. Despite its popularity, and beyond the hunches and intuitions that back the concept, seldom do philosophers consider the nature of multiple realization. (...) The central aim of the thesis is to tackle the somewhat overlooked question: “what is multiple realization?” The rationale is that to find out what philosophical tasks multiple realization can accomplish, we have to know what multiple realization is. The thesis proceeds as follow: In chapter 2, I’ll argue for a methodology for the entire project in answering the question. I’ll argue that there are four desiderata we want from any account of multiple realization, namely, Multiplicity, Naturalness, Physical Realization, and Anti-Reductionism. We should look for an account of multiple realization that could respect the four desiderata in a philosophically satisfactory way. In chapter 3, I’ll look at the alleged origin of multiple realization, Jerry Fodor’s. I’ll reconstruct Fodor’s account of multiple realization. I’ll argue that the major bug of Fodor’s account is his failure in respecting Physical Realization. In chapter 4, I’ll examine Jaegwon Kim’s important critique of Fodor. I’ll argue that Kim’s criticism can be reconstructed as an account of multiple realization that intentionally violates Naturalness. In chapter 5, I’ll look at what I call the Causal Power Subset View of multiple realization as suggested by some philosophers around the turn of the 21st century. I’ll reconstruct an account of multiple realization from their works and argue that their account faces difficulties in reconciling Physical and Anti-Reductionism. I’ll further argue that their account nudges us toward a representational reading of Anti-Reductionism, according to which our seeming commitment to the higher level realized property is, in fact, a partial representation of a complex physical state. In chapter 6, I develop the aforementioned suggestion into a fuller picture. I’ll sketch a representational account of multiple realization and elucidate its plausibility. One result of the thesis is that the desiderata motivating a theory of multiple realization are in tight tension. One has to choose among them. My approach is no exception. I choose to give up Anti-Reductionism and Naturalness, but, as a remedy, I attempt to explain and make sense of the motivations and intuitions backing these two desiderata, arriving at a picture that I am comfortable with, after traveling the long journey.

The "standard account" of Wittgenstein’s relations with the Vienna Circle is that the early Wittgenstein was a principal source and inspiration for the Circle’s positivistic and scientific philosophy, while the later Wittgenstein was deeply opposed to the logical empiricist project of articulating a "scientific conception of the world." However, this telegraphic summary is at best only half-true and at worst deeply misleading. For it prevents us appreciating the fluidity and protean character of their philosophical dialogue. In retrospectively attributing clear-cut positions (...) to Wittgenstein and his interlocutors, it is very easy to read back our current understanding of familiar distinctions into a time when those terms were used in a much more open-ended way. The paper aims to to provide a broader perspective on this debate, starting from the protagonists’ understanding of their respective positions. Too often, the programmatic statements about the nature of their work that are repeated in manifestoes, introductions, and elementary textbooks have occupied center stage in the subsequent secondary literature. Consequently, I focus on a detailed examination of a turning point in their relationship. That turning point is Wittgenstein's charge, in the summer of 1932, that a recently published paper of Carnap's, "Physicalistic Language as the Universal Language of Science", made such extensive and unacknowledged use of Wittgenstein's own ideas that Wittgenstein would, as he put it in a letter to Schlick, "soon be in a situation where my own work shall be considered merely as a reheated version or plagiarism of Carnap’s." While the leading parties in this dispute shared a basic commitment to the primacy of physicalistic language, and the view that all significant languages are translatable, there was a remarkable lack of mutual understanding between them, and deep disagreement about the nature of the doctrines they disputed. Three quarters of a century later, we are so much more conscious of the differences that separated them than the points on which they agreed that it takes an effort of historical reconstruction to appreciate why Wittgenstein once feared that his own work would be regarded as a pale shadow of Carnap’s.

The disappearing agent problem is an argument in the metaphysics of agency. Proponents of the agent-causal approach argue that the rival event-causal approach fails to account for the fact that an agent is active. This paper examines an analogy between this disappearing agent problem and the exclusion problem in the metaphysics of mind. I develop the analogy between these two problems and survey existing solutions. I suggest that some solutions that have received significant attention in response to the exclusion problem (...) have seen considerably less attention in response to the disappearing agent problem. For example, one solution to the exclusion problem is to reject the exclusion assumption. Analogously, one solution to the disappearing agent problem could be to deny the claim that the agent-causal approach and the event-causal approach are mutually exclusive. Similarly, proportionality theories of causation, a solution to the exclusion problem, can be transferred to the disappearing agent problem. After establishing the plausibility of the analogy between the two problems, I examine how this latter solution in particular can be transferred from the one problem to the other. (shrink)

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)

Depth psychology finds empirical validation today in a variety of observations that suggest the presence of causally effective mental processes outside conscious experience. I submit that this is due to misinterpretation of the observations: the subset of consciousness called “meta-consciousness” in the literature is often mistaken for consciousness proper, thereby artificially creating space for an “unconscious.” The implied hypothesis is that all mental processes may in fact be conscious, the appearance of unconsciousness arising from our dependence on self-reflective introspection for (...) gauging awareness. After re-interpreting the empirical data according to a philosophically rigorous definition of consciousness, I show that two well-known phenomena corroborate this hypothesis: (a) experiences that, despite being conscious, aren’t re-represented during introspection; and (b) dissociated experiences inaccessible to the executive ego. If consciousness is inherent to all mentation, it may be fundamental in nature, as opposed to a product of particular types of brain function. (shrink)
