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

In this paper, I argue for a version of panpsychist idealism on first-person experiential grounds. As things always appear in my field of consciousness, there is prima facie empirical support for idealism. Furthermore, by assuming that all things correspond to a conscious perspective or perspectives (i.e., panpsychism), realism about the world is arguably safeguarded without the need to appeal to God (as per Berkeley’s idealism). Panpsychist idealism also has a phenomenological advantage over traditional panpsychist views as it does not commit (...) perceptual experience to massive error by denying that perceived colours are properties of things. Finally, I argue that the subject combination problem for panpsychism has been motivated by the problematic assumption that consciousness is in things. Thinking about subject combination from the first-person perspective is fruitful for reframing the subject combination problem and for seeing how subjects could potentially combine for the idealist.

Most philosophers believe that we have experiences as of temporally extended phenomena like change, motion, and succession. Almost all theories of time consciousness explain these temporal experiences by subscribing to the doctrine of the specious present, the idea that the contents of our experiences embrace temporally extended intervals of time and are presented as temporally structured. Against these theories, I argue that the doctrine is false and present a theory that does not require the notion of a specious present. Furthermore, (...) I argue that the different aspects of temporal experiences arise from different mechanisms operating separately. If the theory is true, then temporal experiences do not tell us anything special about the nature of consciousness and its temporal properties per se. (shrink)

Our perceptual experiences stretch across time to present us with movement, persistence and change. How is this possible given that perceptual experiences take place in the present that has no duration? In this paper I argue that this problem is one and the same as the problem of accounting for how our experiences occurring at different times can be phenomenally unified over time so that events occurring at different times can be experienced together. Any adequate account of temporal experience must (...) also account for phenomenal unity. I look to Edmund Husserl's writings on time consciousness for such an account. (shrink)

The unity of consciousness has so far been studied only as a relation holding among the many experiences of a single subject. I investigate whether this relation could hold between the experiences of distinct subjects, considering three major arguments against the possibility of such ‘between-subjects unity’. The first argument, based on the popular idea that unity implies subsumption by a composite experience, can be deflected by allowing for limited forms of ‘experience-sharing’, in which the same token experience belongs to more (...) than one subject. The second argument, based on the phenomenological claim that unified experiences have interdependent phenomenal characters, I show to rest on an equivocation. Finally, the third argument accuses between-subjects unity of being unimaginable, or more broadly a formal possibility corresponding to nothing we can make sense of. I argue that the familiar experience of perceptual co-presentation gives us an adequate phenomenological grasp on what between-subjects unity might be like. (shrink)

Paper on the renaissance of panpsychism in the contemporary philosophy of mind.

Encyclopedia entry about "Panpsychism".

In my dissertation I critically survey existing theories of time consciousness, and draw on recent work in neuroscience and philosophy to develop an original theory. My view depends on a novel account of temporal perception based on the notion of temporal qualities, which are mental properties that are instantiated whenever we detect change in the environment. When we become aware of these temporal qualities in an appropriate way, our conscious experience will feature the distinct temporal phenomenology that is associated with (...) the passing of time. The temporal qualities model of perception makes two predictions about the mechanisms of time perception; one that time perception is modality specific and the other that it can occur without awareness. My argument for this view partially depends on a number of psychophysical experiments that I designed and implemented myself and which investigate subjective time distortions caused by looming visual stimuli. These results show that the mechanisms of conscious experience of time are distinct from the mechanisms of time perception, as my theory of temporal qualities predicts. (shrink)

Several intrinsic/extrinsic distinctions amongst properties, current in the literature, are discussed and contrasted. The proponents of such distinctions tend to present them as competing, but it is suggested here that at least three of the relevant distinctions (including here that between non-relational and relational properties) arise out of separate perfectly legitimate intuitive considerations: though of course different proposed explications of the informal distinctions involved in any one case may well conflict. Special attention is paid to the question of whether a (...) single notion of property is capable of supporting the various distinctions. (shrink)

Although panpsychism has had a very long history, one that goes back to the very origin of western philosophy, its force has only recently been appreciated by analytic philosophers of mind. And even if many still reject the theory as utterly absurd, others have argued that it is the only genuine form of physicalism. This paper examines the case for panpsychism and argues that there are at least goodprima faciereasons for taking it seriously. In a second step, the paper discusses (...) the main difficulty the theory has to face, the ‘composition problem’. This is the problem of explaining how the primitive experiences that are supposed to exist at the ultimate level of reality could give rise to the unified experience of a human being. What assumptions as to the nature of experience generate the composition problem? Is mental composition impossible in principle or do we simply lack at present any understanding of phenomenal parts and wholes? (shrink)

This thesis explores the possibility of composite consciousness: phenomenally conscious states belonging to a composite being in virtue of the consciousness of, and relations among, its parts. We have no trouble accepting that a composite being has physical properties entirely in virtue of the physical properties of, and relations among, its parts. But a long­standing intuition holds that consciousness is different: my consciousness cannot be understood as a complex of interacting component consciousnesses belonging to parts of me. I ask why: (...) what is it about consciousness that makes us think it so different from matter? And should we accept this apparent difference? (shrink)

The Aristotelian Society’s Virtual Issue is a free, online publication, made publically available on the Aristotelian Society website. Each volume is theme-based, collecting together papers from the archives of the Proceedings of the Aristotelian Society and the Proceedings of the Aristotelian Society Supplementary Volume that address the chosen theme. This year's Virtual Issue includes a selection of papers from across the Society’s fourteen decades, each accompanied by a specially commissioned present-day response. The aim of the volume is to aid reflection (...) on how to go about doing moral and political philosophy, by bringing together papers that bear on their epistemology and methodology. In some cases this involves pieces whose declared focus is on one of those areas, as is the case with Margaret MacDonald’s 1941 essay ‘The Language of Political Theory’ and Mary Midgley’s 1974 article ‘The Neutrality of the Moral Philosopher’. In other cases the editor, Ben Colburn, selected papers whose primary focus is elsewhere, but which include some interesting epistemological or methodological reflections or implications along the way. The contributions from our present-day commentators vary similarly in how far their explicit attention is methodological. Nevertheless, there is throughout a concern on how to ‘be an honest reasoner’, to borrow a phrase from the late Dudley Knowles. (shrink)

This paper has two aims. First, to bring together the models of temporal phenomenology on offer and to present these using a consistent set of distinctions and terminologies. Second, to examine the methodologies currently practiced in the development of these models. To that end we present an abstract characterisation in which we catalogue all extant models. We then argue that neither of the two extreme methodologies currently discussed is suitable to the task of developing a model of temporal phenomenology. An (...) entirely top-down methodology is largely insensitive to empirical findings, while one that is entirely bottom-up is insensitive to both introspective evidence and more general philosophical considerations. We recommend a methodology that falls between these two extremes. (shrink)

This book introduces the reader to Whitehead’s complex and often misunderstood metaphysics by showing that it deals with questions about the nature of causation originally raised by the philosophy of Leibniz. Whitehead’s philosophy is an attempt at rehabilitating Leibniz’s theory of monads by recasting it in terms of novel ontological categories.

This paper explores cosmopsychism’s explanatory aspirations from a programmatic perspective. The bulk of the text consists of an argument in favor of the conclusion that cosmopsychism suffers from no insurmountable individuation problem. I argue that the widespread tendency to view IND as a mirror-image of micropsychism’s combination problem is mistaken. In particular, what renders CP insolvable, namely, the commitment to the coupling of phenomenal constitution with phenomenal inclusion, is, from the standpoint of cosmopsychism, an entirely nonmandatory assumption. I proceed to (...) show that severing this unhappy coupling is the key for defending cosmopsychism against the charge of theoretical incoherence. Moreover, I argue that successful defense against such accusation could be mounted regardless of whether or not we assume cosmic consciousness to be perspectival in nature. In addition, the paper touches upon another foundational issue: cautioning against the popular tendency to identify cosmopsychism’s monism with a mereological unity-in-diversity, and motivating an alternative conception which I call generative monism. Finally, as befitting this volume, I pause to reflect upon the question of which schools of Hindu philosophy might tally best, and connect most fruitfully, with cosmopsychism as I understand it.

Recent philosophical work on temporal experience offers generic models that are often assumed to apply to all sensory modalities. I show that the models serve as broad frameworks in which different aspects of cognitive science can be slotted and, thus, are beneficial to furthering research programs in embodied music cognition. Here I discuss a particular feature of temporal experience that plays a key role in such philosophical work: a distinction between the experience of succession and the mere succession of experiences. (...) I question the presupposition that there is such an evident, clear distinction and suggest that, instead, how the distinction is drawn is context-dependent. After suggesting a way to modify the philosophical models of temporal experience to accommodate this contextdependency, I illustrate that these models can fruitfully incorporate features of research projects in embodied musical cognition. To do so I supplement a modified retentionalist model with aspects of recent work that links bodily movement with musical perception (Godøy, 2006; 2010a; Jensenius, Wanderley, Godøy, and Leman, 2010). The resulting model is shown to facilitate novel hypotheses, refine the notion of context-dependency and point towards means of extending the philosophical model and an existent research program.

In the first part ("Determination"), I consider different notions of determination, contrast and compare modal with non-modal accounts and then defend two a-modality theses concerning essence and supervenience. I argue, first, that essence is a a-modal notion, i.e. not usefully analysed in terms of metaphysical modality, and then, contra Kit Fine, that essential properties can be exemplified contingently. I argue, second, that supervenience is also an a-modal notion, and that it should be analysed in terms of constitution relations between properties. (...) In the second part ("A Theory of Truthmaking"), I first review the literature on ontological commitment, and argue that the notion of truthmaking is better suited to play its explanatory rôle. I then argue that we should take truthmaker theory seriously, and that we should provide actual truthmakers for all truths there are. In the last chapter of this part, I review Armstrong's truthmaker theories and argue that they are unsatisfactory. I generalise my criticism to an argument against truthmaker necessitarianism, the view that truthmakers necessarily make true the truths they are truthmakers of. In the third part ("Properties and their Kind(s)"), I discuss qualitative determination. I present and endorse the truthmaker argument for universals, and defend universalism against friends of tropes, states of affairs and facts. I then give a novel characterisation of the important class of intrinsic properties, building on Lewis' work. With a workable notion of intrinsicness at hand, I argue that relations are ontologically – but not "ideologically" – dispensable: qualitative determination in general is a matter of intrinsic structure. In the future, I plan to add two parts and to publish my thesis as a book: In the fourth part ("Exemplification"), I argue for the existence of an exemplification relation tying universals and particulars together. I derive theoretical benefits from this relation by providing adverbialist theories of modality and tense and identify exemplification with a type of parthood. In the fifth part ("Qua qua qua"), I investigate the curious and interesting ontological category of so-called "qua-objects" (Picasso-as-a-painter, for example) and argue that they exist, are not identical with transworld indidivuals or modal parts and that they provide (contingent) truthmakers for all true predications.

Whitehead's system may be interpreted as a majestic attempt at recasting Leibniz's theory of monads in terms of sounder ontological categories. After a brief introductory section on the sources of Whitehead's knowledge of Leibniz's philosophy, the paper explains why Whitehead turned to Leibniz for metaphysical inspiration. Attention then shifts to Whitehead's understanding of the problems involved with Leibniz's theory of monads and his alternative explanation of monadic causation. Whitehead's endeavour to install windows in Leibniz's monads may not be entirely convincing, (...) but there are philosophical gems scattered here and there in his analyses – true moments of insight that repay close examination.

Aristotle, Dignāga, Descartes, Arnauld, Locke, Brentano, Sartre and many others are right about the nature of conscious awareness: all such awareness comports—somehow carries within itself—awareness of itself . This is a necessary condition of awareness being awareness at all: no ‘higher-order’ account of what makes conscious states conscious can be correct. But is very paradoxical: it seems to require that awareness be somehow already present, in such a way as to be available to itself as object of awareness, in order (...) to be constituted as awareness in the first place. Can anything relate to itself in this way? Can there be a relation that is necessarily one-term, reflexive, non-logical , concretely realizable, dynamically real, such that its holding is a necessary condition of the existence of the thing it holds of? It helps to consider the thought this very thought is puzzling. Many accept the reality of the kind of awareness of awareness posited in and , and think it must be not only ‘pre-reflective’ and ‘non-positional’, but also irrelational or non-intentional. But perhaps such awareness of awareness can be fully relational and fully intentional, and can be legitimately said to be its own object or content, even while being pre-reflective and non-positional.

The hard problem of consciousness arises in most incarnations of present day physicalism. Why should certain physical processes necessarily be accompanied by experience? One possible response is that physicalism itself should be modified in order to accommodate experience: But, modified how? In the present work, we investigate whether an ontology derived from quantum field theory can help resolve the hard problem. We begin with the assumption that experience cannot exist without being accompanied by a subject of experience (SoE). While people (...) well versed in Indian philosophy will not find that statement problematic, it is still controversial in the analytic tradition. Luckily for us, Strawson has elaborately defended the notion of a thin subject—an SoE which exhibits a phenomenal unity with different types of content (sensations, thoughts etc.) occurring during its temporal existence. Next, following Stoljar, we invoke our ignorance of the true physical as the reason for the explanatory gap between present day physical processes (events, properties) and experience. We are therefore permitted to conceive of thin subjects as related to the physical via a new, yet to be elaborated relation. While this is difficult to conceive under most varieties of classical physics, we argue that this may not be the case under certain quantum field theory ontologies. We suggest that the relation binding an SoE to the physical is akin to the relation between a particle and (quantum) field. In quantum field theory, a particle is conceived as a coherent excitation of a field. Under the right set of circumstances, a particle coalesces out of a field and dissipates. We suggest that an SoE can be conceived as akin to a particle—a SelfOn—which coalesces out of physical fields, persists for a brief period of time and then dissipates in a manner similar to the phenomenology of a thin subject. Experiences are physical properties of selfons with the constraint (specified by a similarity metric) that selfons belonging to the same natural kind will have similar experiences. While it is odd at first glance to conceive of subjects of experience as akin to particles, the spatial and temporal unity exhibited by particles as opposed to fields and the expectation that selfons are new kinds of particles, paves the way for cementing this notion. Next, we detail the various no-go theorems in most versions of quantum field theory and discuss their impact on the existence of selfons. Finally, we argue that the time is ripe for a rejuvenated Indian philosophy to begin tackling the three-way relationship between SoEs (which may become equivalent to jivas in certain Indian frameworks), phenomenal content and the physical world. With analytic philosophy still struggling to come to terms with the complex worlds of quantum field theory and with the relative inexperience of the western world in arguing the jiva-world relation, there is a clear and present opportunity for Indian philosophy to make a worldcentric contribution to the hard problem of experience.

Does the self exist? If so, what is its nature? How long do selves last? Galen Strawson draws on literature and psychology as well as philosophy to discuss various ways we experience having or being a self. He argues that it is legitimate to say that there is such a thing as the self, distinct from the human being.

Although T.L.S. Sprigge described idealist philosophy as the stage beyond religion, his pantheistic idealism, while not itself a religion, offers a conception of God that seeks to meet the aspiration of human beings to understand their own place in the universe. While he shared with most mid twentieth century British philosophers a basic assumption of the primacy of experience, Sprigge took this strong empiricist assumption in a Berkeleyian rather than a Humean direction. This enabled him to find a place for (...) the phenomenon of religious consciousness, which he saw as the source of a yearning that can be met by absolute idealism's conception of a 'Whole' that encompasses ourselves and all aspects of our world. He describes this recognition as the faltering adumbration of a truth - one that is sometimes encountered in aesthetic experience, and sometimes more directly in the lives of mystics.The metaphysical basis for this form of absolute idealism is provided by a concept of time in which each fleeting 'now' has a fixed and permanent place, and by a theory of identity according to which personal individuality is dissolved in a unitary 'Whole'.

Recent developments in contemporary natural science (including the evolutionary study of perception, cognitive science, and interpretations of quantum physics) incorporate central idealist positions relating to the nature of representation, the role our minds play in structuring our experience of the world, and the properties of the world behind our representations. This paper first describes what these positions are, and how they are introduced in the relevant theories in terms of precisely formulated scientific analogues. I subsequently consider how this way of (...) looking at philosophical idealism through selected parts of contemporary science can help us to pursue new ways of developing key idealist questions in a way that is integrated with a naturalistically supported endeavour to understand central features of reality.

For Advaita Vedānta, consciousness is to be distinguished from all contents of consciousness that might be introspectively detectable: It is precisely consciousness of whatever contents it is conscious of and not itself one of these contents. Its only nature is, Advaita holds, prakāśa ; in itself it is devoid of any content or structure and can never become an object. This paper elaborates on this kind of understanding of consciousness in order to next explain why it might be fruitful for (...) developing a clear understanding of the nature of the so-called problem of consciousness. Today’s philosophy of mind tends to conceive of consciousness in terms of qualia, thereby taking it as a special kind of object. This renders the antimaterialist claim of the distinctness of consciousness from all physical features vulnerable to the materialist reply that the difference in question might be a merely epistemological matter, i.e., a matter of different modes of givenness without difference in what is thus given. This move, however – this paper argues –, is impossible without resulting in circularity or infinite regress with regard to consciousness in the sense of givenness itself. (shrink)

Physicalism is the most widely accepted metaphysical view today. The thesis of physicalism, however, seems unable to adequately explain the existence and nature of consciousness. Moreover, the thesis is not itself a scientific finding but must be characterized as a metaphysical assumption. Hence, there are strong reasons to explore alternatives to the physicalist view. While metaphysical theses based on classic idealistic views like subjective or absolute idealism have been largely absent from the philosophical debate during most of the 20th century, (...) in the last few decades theses of this kind have been advocated, most notably by John Foster and Timothy Sprigge. Russell’s and Moore’s influential refutations of idealism have been severely questioned by recent scholarship, which means that conventional arguments against absolute idealism appear to be significantly less well-founded than what is usually assumed. With Sprigge’s panpsychistic absolute idealistic metaphysical system as the basis and by incorporating key elements in Foster’s thinking, the present paper outlines an idealistic thesis which, it is argued, first of all escapes the problem of consciousness inherent in physicalism and secondly counters important arguments raised against Sprigge’s views, including the question of personal identity and the problem of the one and the many. In addition, this thesis can be seen as naturalistic in a broad sense, thereby potentially being of existential relevance also within the framework of modernity. Thus, it is the aim of the present paper to argue – although sketchily – that despite its controversial character in the light of contemporary mainstream views, panpsychistic absolute idealism demonstrates a significant explanatory power and is therefore of philosophical interest as a subject for further study.
