Numerical identity is the non-relational sameness of an object to itself. It is concerned with understanding how entities undergo change and maintain their identity. In substance metaphysics, an entity is considered a substance with an essence and such an essence is the source of its power. However, such a framework fails to explain the sense in which an entity is still the entity it was, amidst changes. Those who claim that essence is unaffected by existence are faced with challenge of exploring the epistemic access to such an essence, which is questionable at best. Process metaphysics is a strong candidate for a theory that can ontologically explain regularity and change without appeal to essence. Process and its interactions is the main category. Every process is an emergent organization of constitutive interactions and is individuated on the basis of its interactive powers, that is, the ways in which it interacts with the world around it. Interactions are situated adaptation to changes. In this way, changes are crucial within process metaphysics and are included in the starting point of its investigation. What seems to the naked eyes as one-ness/singularity is a complex process where an organization of interactions is emerging from moment to moment by continually adapting to the changes around and within it. The question of numerical identity over time becomes valid only within substance metaphysics which has no space to accommodate change, due to its allegiance to essence.

In metaphysics, fundamentality is a central theme involving debates on the nature of existents, as wholes. These debates are largely object-oriented in their standpoint and engage with composites or wholes through the mereological notion of compositionality. The ontological significance of the parts overrides that of wholes since the existence and identity of the latter are dependent on that of the former. Broadly, the candidates for fundamental entities are considered to be elementary particles of modern physics (since they appear to play the role of ultimate parts to all phenomena). The paper intends to show the inadequacy of the object-oriented notion of conditionality by pointing out that the parts and wholes possess varying conditions of existence. By alleging that only the parts are ontologically significant is to conflate such conditions and neglect the spectrum of conditions which exist in our world. A proposal for a revised notion of compositionality in terms of structural relatedness is also put forward.

Consciousness has been the bone of contention for philosophers throughout centuries. Indian philosophy largely adopted lived experience as the starting point for its explorations of consciousness. For this reason, from the very beginning, experience was an integral way of grasping consciousness, whose validity as a tool was considered self-evident. Thus, in Indian philosophy, the question was not to move from the brain to mind but to understand experience of an individual and how such an experience is determined through mental structures (and secondarily, the preoccupation with the brain and its relation to the mind). In contrast, cognitive science (the study of mind and cognition through 1 interdisciplinary methods, with emphasis on computational methods) found its debates soaked in discussion which primarily involved the brain and mind. Experience was not considered a primary source of information and its validity had to be established to consider it a source of information of mind. With the rise of physicalism and realization that mental states are correlative to brain states, the body was virtually neglected from involvement in understanding the mind and the attempts to reduce mind to the brain were rampant. The inability to explain subjective experience of an individual through neuroscientific findings alone has urged philosophers to explore other ways of understanding the ontology of mind. Over the last few years, embodied cognition and enactive approach have brought back the body as a central participant in this debate, providing fertile grounds to explain the relation of brain, body and mind. This paper proposes that we understand the brain as a complex system from which the mind emerges. This emergence is marked by the development of novel property of self-consciousness in human beings. The mind is a process which is embedded throughout the body and thus, the body acts as an actualizing medium for the individual. Thus, the brain is a necessary condition for the mind to be while the mind is embedded throughout the body. The brain and mind are in reciprocal causal relationship with one another, as is the body and environment with one another. In this paper, embodied cognition is understood through principles of Merleau Ponty's idea of embodiment, than through Andy Clark and Francis Varela's alone.

This is a (very) introductory paper to a forthcoming existentalist account of moral absolutism and violence. It was written for and presented at ICPR Seminar 2018. In feminist ethics, the freedom to choose one's way of living is primary to the struggle against patriarchy. Such a choice to live a certain way is a manifestation of one's individuality. This assertion of individuality is accompanied by responsibility towards consequences of the way of living. To explore the relation between individuality and responsibility, I develop and build the hypothetical situation of a mother and daughter with different ways of living. The notion of a good life for each of them is mentioned and we ask: To what extent is the daughter responsible for the anguish that the mother undergoes in her assertion of individuality (through her choice of way of living)? My primary aim in this paper is to question the nature of individuality and to probe the claim that individuality is a source of violence. This will involve discussing the scope of responsibility for one's choices and the difficulty in forming a criterion to delineate such a scope.

The relationship between brain and mind has been extensively explored through the developments within neuroscience over the last decade. However, the ontological status of mind has remained fairly problematic due to the inability to explain all features of the mind through the brain. This inability has been considered largely due to partial knowledge of the brain. It is claimed that once we gain complete knowledge of the brain, all features of the mind would be explained adequately. However, a challenge to such a position is downward causation: How do we explain the causal power that mental states exert over brain activities? If we agree that downward causation occurs, then to what extent could a sole explanation of brain activities account for our behaviour? (For they would in themselves be conditioned by the mental states which are left unexplained). This dissertation is an attempt to understand relation between brain and mind through the concept of emergence, placed in the context of complex systems approach. This will create a space to account for the causal power of mental states. The complex systems approach says that as the complexity of a system increases, we witness the emergence of novel qualities and after a certain threshold (of complexity), the emergence of a novel structure. When the body (and correspondingly, brain) reaches a certain level of complexity, the mind emerges. The brain is a complex system from which the mind emerges. The brain, consisting of billions of neurons interacting with each other, regulates the body placed in the environment. The interaction of neurons (local interactions involving self-organization) result in dynamical brain signatures (global synergy). Such signatures are correlative to mental states. Mind is the process of a living organism embodying an intentional stance. This object could be the subject itself or another distinct from the subject. With the emergence of mind, the causal powers of brain are conditioned by the mind. Such a conditioning is evident through the causal efficacy of mental states. While the brain is minimal condition for the mind to emerge, the mind in itself is embedded (showcased/explicated/manifested) throughout the body. The mind is a process that belongs to body-as-a-whole with the novel quality of intentionality. A preliminary to understanding this relation is its metaphysical inclination. A large portion of the history of philosophy of mind has advocated a metaphysics of entities where the mind and body have been seen as two entities with distinct essences. However, such attribution of entity-ship does not take into account the processual nature of these existents (that they are essentially dependent on their environment for their existence and sustenance). Thus, the category of processual unity has been introduced which sought to account for existent as emergent wholes that move towards a stable equilibrium through self-organization. By considering existents to be processual unities, we can account for their identity as a whole-in-itself (what has been called organizational closure) and also for their processual nature. The brain is a component of the body which is a complex system and is representative of the body’s stance in the world. The brain, consisting of billions of neurons interacting with each other, regulates the body placed in the environment. The interaction of neurons (local interactions involving self-organization) result in dynamical brain signatures (global synergy). Such signatures are correlative to mental states. These mental states in turn condition the brain patterns, that allows the embodying of mental states. Thus, the three-way process of the representation of body in the world by the brain, the emergence of mental state through dynamic brain patterns and the reciprocal causal power on the brain patterns by the mental states marks embodiment. The relation between brain, body and mind can be outlined as follows: A. There are complex interactions in the brain. These interactions are representative of the body’s stance in the world and are present in form of dynamical brain signatures. B. The dynamical brain signatures lead to emergence of mind as a process. The mental state has causal power which conditions the brain. C. The brain conditioned by causal power of the mind carries out embodiment of the mind throughout the body. In the dissertation, an exposition on relation between brain and mind through complex system approach is followed by a brief on relation between body and mind. The radical embodiment approach adopts the nonlinear dynamic systems theory to understand relation of brain, body and mind. It states a shift from mapping of cognitive states onto Neural Correlates of Consciousness to their mapping through dynamic brain signatures. Every mental state is embedded throughout the body. The dissertation explores the three features of consciousness, intentionality and qualia. These have previously formed a challenge within a dualistic framework and the dissertation intends to show a direction in which they can be accounted for, within the complex systems approach and radical embodiment viewpoint. After a certain threshold of the rate of production of cell assemblies is bypassed, we become conscious of the representation itself. This leads to emergence of phenomenal states. Qualia is the qualitative character of such states, which belong to the body-as-a-whole and for this reason, cannot be reduced to properties of any of the components from which it emerges (the dynamic brain signatures) or in which it is embodied (the body and its individual parts) alone. Intentionality is the novel property of mind of moving towards a certain set of attractors where attractors refer to the states that the system prefers (which would positively contribute to its fitness). The scope of this dissertation is to delineate the relation of brain to the mind and unravel some persistent troubles of philosophy of mind within such delineation. The types of components and their relation within the mind preceded by a thorough study of how the mind is embodied is an area yet to be extensively explored in the coming works.

Over the past decade, in contrast to the traditional analytic version of metaphysics, a brand of metaphysics that prioritizes collaboration and corroboration with sciences has emerged in the form of scientific metaphysics. While there has been a shift from the methodological dependence of analytic metaphysis on intuition, and conceptual analysis to the methodological preference for empirically-motivated metaphysical insights in scientific metaphysics, such a shift has not penetrated the foundational aims. Scientific metaphysics continues to probe the nature and structure of reality, much like its analytic counterpart and in this process, develops ontologies. Broadly two kinds of ontologies are furnished - global metaphysical ontologies and local scientific ontologies. In this paper, I highlight the challenges with developing such ontologies in scientific metaphysics. With Ladyman-Ross’ Information Theoretic Structural Realism as a case in point, I contest that the former suffers from representational indeterminacy and redundancy. Further, I note the possibility that eventually, local scientific ontologies might be replaced by scientific theories and in such a scenario, the former are best conceived as interim metaphysical supports for the latter.

In the recent years, attempts to relate metaphysics and sciences have taken various alternative forms such as metaphysics applied to science, metaphysics of science, and scientific metaphysics. In this article, I focus on scientific metaphysics and specifically explore the challenges with developing ontologies through four arguments. The Argument from Representational Indeterminacy highlights that global ontologies fail to clearly identify their target phenomenon. The Argument from Independent Inaccessibility explores the methodological difficulty of accessing a world that is independent of specific sets of phenomena. The Argument from Conceptual Mismatch focuses on the tendency of local ontologies to pick out arbitrary scientific concepts, adapting them to study phenomena where they might not fit well. Finally, the Argument from Eliminative Prophecy details the possibility that local ontologies could eventually be rendered redundant by mature versions of scientific theories. In the end, given these challenges, I recommend an eliminativist stance toward ontology development.

Abstract:In contemporary debates, the materialist ethics of Cārvāka has primarily been discussed in relation to and on the backdrop of ethical schema suited for systems whose metaphysics permits the notions of God and soul. This essay elaborates on this insight and draws attention to the significance of the metaphysical backdrop of ethical theories. We also briefl y discuss two aspects of Cārvāka materialistic ethics, which attends to the metaphysics of Cārvāka justly, namely the crucial role of pain in their ethical theory and the lack of inherent moral value to actions.

The identity of an academic discipline is essentially tied to production and reproduction of its disciplinary knowledge. This, in turn, determines the criteria of academic achievement for academicians belonging to a particular discipline. The ability of an academician to contribute to the disciplinary knowledge through publication of high-impact papers is considered to be of highest value in academic disciplines. This constitutes an essentialist paradigm of understanding academic disciplines. Such a paradigm, however, undervalues other equally important forms of academic labour, like academic service, which support, develop and repair the academic world through practice of care. In his paper, the essentialist paradigm is critically appraised through Paperwinner’s Model, an adaptation of Breadwinner’s Model. Through the lens of ethics of care, specifically Joan Tronto’s responsibility-based ethics, the paper offers an alternate paradigm, the deflationary perspective on academia, to acknowledge and evaluate the significance of caring practices. The paper concludes with a formative suggestion to institutionally recognize and reward care through service-intensive positions.

This paper examines the often-overlooked yet crucial role of carework within the academic ecosystem. Challenging the dominant paradigm that prioritizes research output, the paper argues for recognizing academic labor as a spectrum where teaching, research, and service hold equal value. Drawing on Rajan's (2023) framework of “academic carework,” the paper demonstrates the inseparable link between care and knowledge, highlighting how carework forms the foundation for knowledge production and reproduction. The analysis situates academic careworkers within the complex administrative landscape of higher education institutions, exploring the challenges posed by managerialism and external pressures. The paper introduces the “Argument from Shared Paradigm,” positing that academics, through their shared experiences and values, are uniquely positioned to advocate for and safeguard care-centered practices in research and teaching. By recognizing carework's essential contributions, this paper calls for a re-evaluation of academic reward systems and a shift towards a more inclusive academic culture.
