According to Zhiyi 智顗 (538–597), the founder of the Chinese Buddhist Tiantai school 天台宗, “one object is all objects;” hence, all objects are profoundly interconnected. In this paper, I critically examine Zhiyi’s metaphysics of objects as presented in the historical Tiantai texts and subsequently develop a contemporary and accessible thesis of interconnectedness by integrating Zhiyi’s views with resources from contemporary analytic philosophy, particularly relative identity. By drawing on Zhiyi’s insights and incorporating contemporary philosophical ideas, I also illustrate how historical Chinese (...) Buddhism and contemporary analytic metaphysics can be mutually informing. (shrink)

Consciousness is connected with the fact that a subject is aware and open to the manifestation of whatever appears. Existence, by contrast, is used to express the fact that something is given in experience, is present, or is real. Usually, the two notions are taken to be somehow related. This chapter suggests that existence is at best introduced as a metaphysical (or meta-experiential) concept that inevitably escapes the domain of conscious experience. In order to illustrate this claim, two case studies (...) are considered. The first case is provided by Descartes’s famous treatment of consciousness and existence in his Meditations on First Philosophy. The second case is meant to contrast the Cartesian approach by taking the opposite route, as delineated by Emanuele Severino (1929–2020) in his ‘fundamental ontology’. (shrink)

This volume takes cue from the idea that the thought of no philosopher can be understood without considering it as the result of a constant, lively dialogue with other thinkers, both in its internal evolution as well as in its reception, re-use, and assumption as a starting point in addressing past and present philosophical problems. In doing so, it focuses on a feature that is crucially emerging in the historiography of early modern philosophy and science, namely the complexity in the (...) production of knowledge. The book explores the applicability of this approach to a long-considered armchair philosopher, namely René Descartes, who is now more and more understood as a full-blown scientist, networker, and intellectual éminence grise rather than as the mere philosopher of the cogito, as well as the originator of different ‘Cartesianisms’ which encompassed many ideas and approaches for long captured by dichotomic historiographical categories as rationalism and empiricism, or speculative and experimental philosophy. The essays gathered in the volume aim to address the ways in which Descartes’s philosophy evolved and was progressively understood by scientists, philosophers, and intellectuals from different contexts and eras, either by considering direct interlocutors of Descartes such as Isaac Beeckman and Elisabeth of Bohemia, early modern thinkers who developed upon his ideas and on particular topics as Nicolas Malebranche or Thomas Willis, those who adapted his overall methodology in developing new systems of knowledge as Johannes Clauberg and Pierre-Sylvain Régis, and contemporary thinkers from continental and analytic traditions like Emanuele Severino and Peter Strawson.

The question whether Buddhism can enter a fruitful dialogue with modern science has come under critical scrutiny in recent years. This paper considers Evan Thompson's appraisal of that dialogue in Why I am Not a Buddhist, focussing on four areas of disagreement: (i) the suitability of evolutionary psychology as a framework of analysis for Buddhist moral psychological ideas; (ii) the issue of what counts as the core and main trajectory of the Buddhist intellectual tradition; (iii) the scope of naturalism in (...) the relation between science and metaphysics, and (iv) whether a Madhyamaka-inspired anti-foundationalist stance can serve as an effective platform for debating the issue of progress in science. My main argument is that while Buddhist ideas about mind and cognition can expand the range of conceptual possibilities in framing core debates in the mind sciences, they cannot supplant the empirical claims to knowledge for which scientific naturalism so far provides the most viable basis.

The Introduction to Sartre’s Being and Nothingness (B&N) contains a condensed, cryptic argument – the ‘ontological proof’ – that is meant to establish a position ‘beyond realism and idealism’. Despite its role in establishing the fundamental ontological distinction of B&N – the distinction between being-for-itself and being-in-itself – the ontological proof has received very little scholarly attention. My goal is to fill this lacuna. I begin by clarifying the idealist position Sartre attacks in the Introduction to B&N: Husserl’s idealism as (...) interpreted by Aron Gurwitsch and Roman Ingarden. I then propose a new interpretation of the ontological proof that gives a central role to the transparency of experience. On this interpretation, Sartre argues from the ‘emptiness’ of consciousness – its purely relational nature – to the existence of mind-independent substance (being-in-itself). In assessing the strengths and weaknesses of Sartre’s case against idealism, I put him in critical dialogue with contemporary work in metaphysics and the philosophy of mind. (shrink)

According to metaphysical coherentism, grounding relations form an interconnected system in which things ground each other and nothing is ungrounded. This potentially viable view’s logical territory remains largely unexplored. In this paper, I describe that territory by articulating four varieties of metaphysical coherentism. I do not argue for any variety in particular. Rather, I aim to show that not all issues which might be raised against coherentism will be equally problematic for all the versions of that view, which features far (...) more nuance and diversity than is typically ascribed to it.

Jan Westerhoff defends an account of thoroughgoing non-foundationalism that he calls “irrealism,” which is implicitly modeled on a Madhyamaka Buddhist view. In this paper, I begin by raising worries about the irrealist’s account of human cognition as taking place in a brain-based representational interface. Next, I pose first-order and higher-order challenges to how the irrealist—who defends a kind of global error theory—can sensibly accommodate an unlocalized appearance-reality distinction, both metaphysically and epistemologically. Finally, although Westerhoff insists that irrealism itself is not (...) an ontological theory and that the irrealist’s rejection of absolutely general quantification precludes his commitment to any ultimately true theories, I propose strategies inspired by the Svātantrika commentarial tradition of Madhyamaka for how the irrealist might develop a lightweight account of unrestricted quantification that could be used to advance a lightweight ultimately true theory. This, I suggest, may allow the irrealist to (i) preserve a commitment to an unlocalized appearance-reality distinction, (ii) underwrite a distinction between ordinary veridical states and metaphysically accurate epistemic states, and (iii) provide an explanation for the massive error that he claims characterizes ordinary cognition.

This paper argues that some defenses of global antirealism that critique both epistemic foundationalism and ontological priority foundationalism (e.g., Westerhoff 2020) turn on a false dilemma that ignores non-representational approaches to consciousness and cognition. Arguments against the existence of an external world and against introspective certainty, typically draw on a range of empirical findings (mainly about the brain-based mechanisms that realize cognition) and that are said to lend support to irrealism. Theories that incorporate these findings, such as the interface theory (...) of perception and predictive processing, not only retain the notion of the veil of perception, but have continued to assign to it an important theoretical role. While the mathematical frameworks these theories employ do make them viable candidates, neither theory is moving in a direction that would suggest global anti-realism is the more plausible attitude. Rather, I argue that the new paradigm of 4E cognitive science (embodied, embedded, enactive, extended) bolsters epistemological and metaphysical realism. (shrink)

This paper examines four central issues prompted by Thompson's recent critique of the Buddhist modernism phenomenon: (i) the suitability of evolutionary psychology as a framework of analysis for Buddhist moral psychological ideas; (ii) the issue of what counts as the core and main trajectory of the Buddhist intellectual tradition; (iii) the scope of naturalism in the relation between science and metaphysics, and (iv) whether a Madhyamaka-inspired anti-foundationalism stance can serve as an effective platform for debating the issue of progress in (...) science. The main argument of this paper is that while the mind sciences may corroborate some aspects of the Buddhist model of mind, they also call into question some core Buddhist ideas. Hence, if Buddhism is to enter into a fruitful dialogue with the mind sciences, it must be shown to complement the empirical claims to knowledge for which scientific naturalism so far provides the most viable basis.

The Idea of a unified foundation of all reality has long been core to many attempts at a fundamental ontology, as well as many arguments for the divine. In medieval India a cluster of arguments for metaphysical inheritance, causal entanglement, the impossibility of fundamental relations and more, were advanced together to show there must be an ultimate and unified ground. But foundationalism has been under attack in both recent metaphysics, and Buddhist philosophy. This article unpacks Vedānta’s defense of divine foundationalism (...) against Madhyamaka Buddhism’s metaphysical nihilism. Firstly, we look at how inheritance arguments for ultimate ground aimed to circumvent the possibility of infinite regress. Secondly, we assess three arguments that this ground is a unified modal anchor, with entangled causal power, providing a connective medium for all phenomena. We address some caveats and limitations, but go on to argue that if they are right, they circumvent the Buddhists’ ‘dualistic’ assumption that if the empirical world is mere imagined convention, it needs no explanation. Monists and nihilists are allies against excessively realist ontologies, but these arguments make a compelling case for some unified fundamental nature from which, as the Upaniṣads put it, all things emerge like sparks from a fire.

This article describes the ultimate ground of reality, Brahman, as a single power unfolding in concert in all things. It uses counterfactual argumentation to imply that a cosmos must consist of telic causal orders or manifested ‘powers’ as its most granular building block – and that they must be unified into a single whole. It is based on an argument for a single causally-conditioning substrate of all things recorded in India’s classical Sāṃkhya Kārikā and Brahma Sūtras; this was used by (...) scholastic Vedāntic thinkers including the non-dualist Śaṃkara and the ‘transformationist’ Bhedābheda thinker Śrīnivāsa. It takes up arguments for satkārya, the pre-existence of a thing’s various transformations in potentio within its substrate, and employs them to paint a picture of reality as an ordered yet entangled pattern of causal trajectories. These manifest as the changing world we know. While Vedānta’s main motivation for making the arguments was to prove monism, this conception of an ‘immanent cause’ of all was also seen as divine. We see how this accords with moves in contemporary analytic philosophy to shift away from a broadly Humean model of constant conjunctions (reminiscent of key Buddhist approaches) toward a Neo-Aristotelian ‘metaphysics of powers’. But we also indicate how it may go further than most modern powers-metaphysicians in proposing a deeper connection between powers and what it is for there to be a cosmos at all. (shrink)

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.

A prominent Thomistic cosmological argument maintains that an infinite regress of causes, which exhibits a certain pattern of ontological dependence among its members, would be vicious and so must terminate in a first member. Interestingly, Jonathan Schaffer offers a similar argument in the contemporary grounding literature for the view called metaphysical foundationalism. I consider the striking similarities between both arguments and conclude that both are unsuccessful for the same reason. I argue this negative result gives us indirect reason to consider (...) metaphysical infinitism as a genuine possibility, the view that chains of ontological dependence or ground can descend indefinitely.

The aim of this paper is to assess the relation between causation and the notion of emptiness described in Buddhist philosophy. While the Madhyamaka school argues that some entity’s being caused implies its being empty, some contemporary authors have argued that there is a ‘Humean’ regularity account of causation that can both be understood as a plausible model of the earlier Buddhist Abhidharma account of causation and also block the Madhyamaka inference from causation to emptiness. After describing the Abhidharma account (...) of causation, the ‘Humean’ regularity account and the Madhyamaka argument from causation to emptiness, we assess some ways in which this argument may be developed, with particular focus on the ‘ladder of causation’ and on the Madhyamaka account of time. The debate about the relation between causation and emptiness, it appears, is a facet of a more comprehensive metaphysical debate between a (moderate) foundationalism and a thoroughgoing anti-foundationalism.

This study sheds light on a key concept of Yogācāra intersubjectivity that played a significant role in medieval Chinese Yogācāra. Specifically, it analyzes how Kuiji 窺基 (632–682) reinterprets adhipati (activating and amplifying influence; Ch: zengshang 增上 or zengshang li 增上力 or zengshang yuan 增上緣) to account for intersubjective karmic interactions across different lifeworlds in the events of teaching and killing.As this line of investigation shows, Kuiji’s theory of adhipati attempts to sidestep the entanglement of the problems of intersubjectivity and incommensurable (...) worlds in Yogācāra. Extant scholarship on intersubjectivity often presumes one spatio-temporal world populated by sentient beings and insentient objects, which is fundamentally at odds with the Yogācāra tenet that each mental stream generates its distinct lifeworld. To address the pragmatic question of how different mental continuums of consciousnesses can impinge into each other’s lifeworlds, Kuiji employed adhipati in a specific way to account for intersubjective interplay across different, potentially incommensurable worlds. In this framing of intersubjectivity, the problem of one world or many worlds is explained non-dualistically: these lifeworlds are neither the same nor different, neither one nor many, but karmically interconnected.Expanding on recent discussions of the puzzle of intersubjectivity in Yogācāra, this paper shows that Kuiji’s deployment of adhipati provides an account of genuine intersubjectivity in which different mental continuums are recognized as subjects and engage in causal interactions among different spatio-temporal worlds. In Kuiji’s framing, this genuine intersubjectivity gives rise to the sense of one shared world. (shrink)

This paper seeks to reconstruct the meaning of existence in the Pāli discourses of the Buddha by considering how the notion is used in the most systematic contexts in which it appears, and how it could be best interpreted. The discourses are concerned with how existence is used to support and consolidate a certain attitude of ownership, appropriation, and entitlement over contents of experience, in virtue of which one can claim that this or that is ‘mine’. The problem with this (...) move is that it seems to require a degree of stability that is at odds with the fundamental uncertainty (anicca) of all conditioned realities. Existence is used to somehow cover up uncertainty, and thus allow for a semblance of genuine ownership and possession, while in fact possession and ownership are just deluded views doomed to be contradicted by the structural uncertainty of actual experience. This reading entails that the early discourses do share with later traditions an anti-realist inspiration, which is worth exploring in its own right. (shrink)

I’ll argue that one particular argument of Nāgārjuna’s against causation in the Mūlamadhyamakakārikā deserves careful consideration from the perspective of contemporary western metaphysics. To show why this is the case, I’ll offer an interpretation of the key passages which differs from at least one popular reading. I’ll then aim to show that a whole swathe of metaphysical views about causation are problematic in light of Nāgārjuna’s argument, so interpreted. I’ll conclude, however, that one contemporary view in metaphysics has the means (...) to respond to this argument: Ontic Structural Realism. (shrink)
