Unity of science was once a very popular idea among both philosophers and scientists. But it has fallen out of fashion, largely because of its association with reductionism and the challenge from multiple realisation. Pluralism and the disunity of science are the new norm, and higher-level natural kinds and special science laws are considered to have an important role in scientific practice. What kind of reductionism does multiple realisability challenge? What does it take to reduce one phenomenon to another? (...) How do we determine which kinds are natural? What is the ontological basis of unity? In this Element, Tuomas Tahko examines these questions from a contemporary perspective, after a historical overview. The upshot is that there is still value in the idea of a unity of science. We can combine a modest sense of unity with pluralism and give an ontological analysis of unity in terms of natural kind monism. This title is available as Open Access on Cambridge Core. (shrink)

According to conventional wisdom, the split-brain syndrome puts paid to the thesis that consciousness is necessarily unified. The aim of this paper is to challenge that view. I argue both that disunity models of the split-brain are highly problematic, and that there is much to recommend a model of the split-brain—the switch model—according to which split-brain patients retain a fully unified consciousness at all times. Although the task of examining the unity of consciousness through the lens of the split-brain (...) syndrome is not a new one—such projects date back to Nagel’s seminal paper on the topic—the time is ripe for a re-evaluation of the issues.

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)

It is common to hold that our conscious experiences at a single moment are often unified. But when consciousness is unified, what are the fundamental facts in virtue of which it is unified? On some accounts of the unity of consciousness, the most fundamental fact that grounds unity is a form of singularity or oneness. These accounts are similar to Newtonian views of space according to which the most fundamental fact that grounds relations of co-spatiality between various points (...) (or regions) of a space is the fact that these points (or regions) are parts of the same single space. In this paper, I sketch and defend an alternative account of unity of consciousness. Very roughly, the view holds that experiences are unified when they are connected in the right way. In this respect, the view is analogous to Leibnizian views of space according to which the oneness of space emerges from certain conditions over spatial relations. The Leibnizian alternative has significant implications for our understanding of the metaphysics of conscious experience, the cognitive architecture of the mind and our assessment of the conditions under which unity of consciousness breaks.

Understanding comes in a variety of forms. This essay argues for the unity of these forms, against the common tendency to view them as fundamentally heteronomous, or disunified. After identifying ten core features of genuine understanding, which enable an argument for the existence of two distinct types of understanding, theoretical and practical, the essay poses a dilemma for theories that view them as disunified. Subsequently, it develops and defends a general account of understanding in terms of conceptions. What unifies (...) diverse forms of understanding, on this account, is a generic cognitive structure—given by the notion of a noetic conception—that is realized in different ways in various cases.

Marx says of alienated labor that it does not “belong” to the worker, that it issues in a product that does not belong to her, and that it is unfulfilling, unfree, egoistically motivated, and inhuman. He seems to think, moreover, that the first of these features grounds all the others. All of these features seem quite independent, however: they can come apart; they share no obvious common cause or explanation; and if they often occur together, this seems accidental. It is (...) not clear, then, how Marx’s concept of alienated labor could possess the strong unity that he takes it to have. This article defends a reinterpretation of the concept that explains this unity. The various features of alienated labor, the article argues, all follow from a single, hitherto underappreciated feature of its formal motivational structure: the fact that such labor is motivated not by its product but by an incentive.

The question of the unity of consciousness is often treated as the question of how different conscious experiences are related to each other in order to be unified. Many contemporary views on the unity of consciousness are based on this bottom-up approach. In this paper I explore an alternative, top-down approach, according to which (to a first approximation) a subject undergoes one single conscious experience at a time. From this perspective, the problem of unity of consciousness becomes (...) rather the problem of how we can distinguish a multiplicity of goings-on within our conscious experience at any time, given that it is unique. I will present three possible top-down approaches to unity of consciousness, which I call Priority unity monism, Existence unity monism, and Brentanian unity monism. Priority monism and Existence monism are defined in analogy with the homonymous metaphysical theories of object constitution. Brentanian monism retraces Franz Brentano’s view on unity of consciousness, and is defined by appeal to some of his mereological ideas. I will argue that the latter is the best top-down approach to unity of consciousness. (shrink)

In the Groundwork and all three Critiques, Kant expresses the hope of eventually unifying theoretical and practical reason in one system, with a principle common to both. But he never clarifies what this principle is, leaving scholars to advance different possibilities. I advance a new response to this problem: I claim that Kant begins to refer to what he calls the ‘autonomy of ideas of reason’ in his final decade, enabling a new approach to finally bridging the theoretical and the (...) practical. This concept of autonomy, however, is no longer equivalent to the moral autonomy attributed to the self-legislating will, nor does it refer to the spontaneity of theoretical reason. Instead, it corresponds to the autonomy ascribed to reflective judgment in representing both theoretical and practical ideas of reason. Thus, this conception furnishes a principle, the principle of purposiveness, which I propose as the unifying principle Kant had been seeking. (shrink)

This essay argues that Plato in the Republic needs an account of why and how the three distinct parts of the soul are parts of one soul, and it draws on the Phaedrus and Gorgias to develop an account of compositional unity that fits what is said in the Republic.

This report highlights and explores five questions which arose from The Unity of Consciousness and Sensory Integration conference at Brown University in November of 2011: 1. What is the relationship between the unity of consciousness and sensory integration? 2. Are some of the basic units of consciousness multimodal? 3. How should we model the unity of consciousness? 4. Is the mechanism of sensory integration spatio-temporal? 5. How Should We Study Experience, Given Unity Relations?

The present thesis explores some metaphysical issues concerning biochemical kinds and the relations between chemical and biological properties and phenomena. The main result of this thesis is that there is something sui generis about biochemical kinds. This result is motivated by two theoretical steps. The first is characterising biochemical functions as weakly emergent from the chemical structure [Chapter 3, Chapter 6]. The second is via an account for which biochemical kinds are natural categories [Chapter 4, Chapter 7]. The thesis comprises (...) four parts. Part I [Chapter 1, Chapter 2] aims to offer the methodological and conceptual tools that underpin this research. Chapter 1 presents the debate on the unity of science and the motivation of the research. Chapter 2 presents the account of natural kinds that will be used throughout the thesis. Part II [Chapter 3, Chapter 4] offers a detailed metaphysical analysis of the molecular gene. Chapter 3 argues that molecular genes are weakly emergent from nucleic acids. Chapter 4 argues that the category "molecular gene" can be deemed a natural kind, following the account presented in Chapter 2. Part III [Chapter 5, Chapter 6, Chapter 7] explores some of the themes related to biochemical kinds and generalises some of the results from Part II. Chapter 5 considers biochemical functions and how functional attribution should be interpreted for biochemical molecules. Chapter 6 considers the relation between biochemical functions and structure, spelt in terms of weak emergence and explores unity in biochemistry. Chapter 7 considers the topic of biochemical kinds per se and argues that biochemical kinds are natural categories. Part IV [Chapter 8] elucidates the main outcome and the implications that this research can have for future discussion in the philosophy and metaphysics of biochemistry and the unity of science.

The goal of this paper is to raise a few questions about Bayne s mereological account of the unity of consciousness. In Section 1, I raise a few clarificatory questions about the account and the thesis that consciousness is necessarily unified. In Sections 2 and 3, I offer an alternative view of unity of consciousness and contrast it with Bayne's view. I call this view the connectivity account. These sections prepare the ground for the main question of this (...) article: why should we prefer Bayne's mereological view to the connectivity view? (shrink)

In the section ‘Unity and Objectivity’ of The Bounds of Sense, P. F. Strawson argues for the thesis that unity of consciousness requires experience of an objective world. My aim in this essay is to evaluate this claim. In the first and second parts of the essay, I explicate Strawson's thesis, reconstruct his argument, and identify the point at which the argument fails. Strawson's discussion nevertheless raises an important question: are there ways in which we must think of (...) our experiences if we are to self-ascribe them? In the third part of the essay, I use Kant's remarks concerning the passivity of experience to suggest one answer to this question: in self-ascribing experiences, we must be capable of thinking of them as passive to their objects. This can be used to provide an alternative route from unity to objectivity. (shrink)

As a working hypothesis for philosophy of science, the unity of science thesis has been decisively challenged in all its standard formulations; it cannot be assumed that the sciences presuppose an orderly world, that they are united by the goal of systematically describing and explaining this order, or that they rely on distinctively scientific methodologies which, properly applied, produce domain-specific results that converge on a single coherent and comprehensive system of knowledge. I first delineate the scope of arguments against (...) global unity theses. However implausible old-style global unity theses may now seem, I argue that unifying strategies of a more local and contingent nature do play an important role in scientific inquiry. This is particularly clear in archaeology where, to establish evidential claims of any kind, practitioners must exploit a range of inter-field and inter-theory connections. At the same time, the robustness of these evidential claims depends on significant disunity between the sciences from which archaeologists draw background assumptions and auxiliary hypotheses. This juxtaposition of unity with disunity poses a challenge to standard positions in the debate about scientific unity. (shrink)

The main task of the paper is to explore Kant’s understanding of what unites the three kinds of judgment that he regards as the signature judgments of the three fundamental faculties of the mind--theoretical, practical and aesthetic judgments--in a way that preserves their fundamental differences. I argue that these are differences in kind not only in degree; or, in the terms I motivate in the paper, differences in form. Thus, I aim to show that (1) the Romantic unity of (...) knowing, doing, and enjoying is not only inspired by Kant, but is in Kant’s own writings, and that (2) Kant understands this unity as a unity within a categorical variety: for him, theoretical judgment, practical judgment, and aesthetic judgment are the paradigmatic judgments of three formally different and irreducible rational capacities. I argue that a chief component in understanding the unity in this multiplicity is the imagination. This is because lawfulness turns out to be an essential mark of the “high” or “rational” aspects of the mind. But, for Kant, human beings can be lawful, and thus rational, in and of their world, only insofar as they are also imaginative. It is the imagination that allows us to be rational in our empirical world: to be rational animals. (shrink)

I argue—contra moderate grounding pluralists such as Kit Fine and more extreme grounding pluralists such as Jessica Wilson—that there is fundamentally only one grounding/in-virtue-of relation. I also argue that this single relation is indispensable for normative theorizing—that we can’t make sense of, for example, the debate over consequentialism without it. It follows from what I argue that there is no metaethically-pure normative ethics.

From a felt, introspective perspective, one can identify various kinds of unity amongst all of one’s experiential parts. Most fundamentally, all of the states you are experiencing right now seem to be phenomenally unified, or, felt together. This introspective datum may lead one to believe that where consciousness exists, it always has this structure: there is always a numerically singular subjective perspective on a unified experiential field. In this dissertation, I expose this intuition and subject it to critical scrutiny.

In this essay I argue that the central problem of Aristotle’s Metaphysics H (VIII) 6 is the unity of forms and that he solves this problem in just the way he solves the problem of the unity of composites – by hylomorphism. I also discuss the matter– form relationship in H 6, arguing that they have a correlative nature as the matter of the form and the form of the matter.

Perception is our key to the world. It plays at least three different roles in our lives. It justifies beliefs and provides us with knowledge of our environment. It brings about conscious mental states. It converts informational input, such as light and sound waves, into representations of invariant features in our environment. Corresponding to these three roles, there are at least three fundamental questions that have motivated the study of perception. How does perception justify beliefs and yield knowledge of our (...) environment? How does perception bring about conscious mental states? How does a perceptual system accomplish the feat of converting varying informational input into mental representations of invariant features in our environment? -/- This book presents a unified account of the phenomenological and epistemological role of perception that is informed by empirical research. So it develops an account of perception that provides an answer to the first two questions, while being sensitive to scientific accounts that address the third question. The key idea is that perception is constituted by employing perceptual capacities - for example the capacity to discriminate instances of red from instances of blue. Perceptual content, consciousness, and evidence are each analyzed in terms of this basic property of perception. Employing perceptual capacities constitutes phenomenal character as well as perceptual content. The primacy of employing perceptual capacities in perception over their derivative employment in hallucination and illusion grounds the epistemic force of perceptual experience. In this way, the book provides a unified account of perceptual content, consciousness, and evidence. (shrink)

_Kant’s Reason_ (2023) is an excellent study that develops an original set of interpretive claims and shows their relevance for contemporary theories of rationality. At the core of Karl Schafer’s project is the following thesis: that Kant’s account of reason is unified as a power of comprehension in both its theoretical and practical activities. The aim of my paper is to examine this thesis against Kant’s doctrine of the Highest Good. In §1, I question some claims Schafer makes about the (...) Highest Good. Then, in §2 and §3, I consider how we might develop a more detailed reading of this doctrine along the lines of Schafer’s project. §4 concludes. (shrink)

This paper focuses on Nietzsche’s claim that suffering is closely related to the realization of certain perfectionist values, such as artistic excellence. According to Bernard Reginster, creative achievement consists in overcoming suffering, and therefore, suffering is an essential ingredient of creative achievement. Because suffering forms an essential part of a valuable whole in this way, Reginster argues that we must in turn value suffering ‘for its own sake’. This paper argues that Reginster’s position is open to the following objection: from (...) the fact that suffering is an essential part of a valuable whole, it does not follow that suffering is itself valuable. Rather, by taking advantage of the principle of organic unities, it would have to form an essential part of a valuable whole in a particular way. The author considers two ways the principle might be attributed to Nietzsche’s views on suffering: first, as an ‘enabling condition’, in which suffering allows for a whole that outweighs its disvalue; and second, as ‘a contributor’, in which suffering positively contributes value to the whole. The paper explores how Nietzsche’s ethics turns out to be crucially informed by this conceptual distinction. (shrink)

The paper studies, within the framework of Martin Heidegger's narrative of the history of metaphysics, two perspectives on the unity of being: the "protometaphysical" perspective of Parmenides, the thinker of the "first beginning" of Western philosophy, and the postmetaphysical perspective of Heidegger, situated in the ongoing transition from the Hegelian and Nietzschean end of metaphysics to a forthcoming "other beginning" of Western thought. Both perspectives involve a certain "crisis", in the literal sense of the Greek krisis, "distinction," "decision." Parmenides' (...) goddess exhorts the thinker to decide for being in the sense of pure intelligible accessibility or presence and to exclude all references to non-accessibility and non-presence. This is the foundation of the Parmenidean thesis of the unity of being. In the Heideggerian perspective, by contrast, meaningful presence is seen as constituted precisely by references to a withdrawing meaning-context, to background dimensions that in themselves are not immediately present. Since presence is constituted only in terms of non-presence, the "decision" or "crisis" between presence and non-presence is an unresolvable and irreducible feature of postmetaphysical thinking.

Suárez held that the vital faculties of the soul are really distinct from the soul itself and each other and that they cannot causally interact. This means that he needed to account for the connections between the activities of the faculties: they both interfere with and contribute to each other’s activities. Suárez does so by giving the soul a direct causal role in these activities. This role requires the unity of the soul of a living being and Suárez used (...) it to argue against the view that a living being, in particular a human being, has more than one soul. This line of thought displays some affinity with arguments for the simplicity of the soul from the unity of consciousness. One important difference is that Suárez was talking not just about mental activities but about all vital activities. (shrink)

I argue that using information from a cognitive representation to guide the performance of a primary task is sufficient for intellectual attention, and that this account of attention is endorsed by scientists working in the refreshing, n-back, and retro-cue paradigms. I build on the work of Wayne Wu, who developed a similarly motivated account, but for perceptual attention rather than intellectual attention. The way that I build on Wu’s account provides a principled way of responding to Watzl’s challenge to Wu, (...) according to which Wu’s style of account is unintuitively broad. The fact that I find unity in the practice of science puts us in a position to resist the claim that scientists studying intellectual attention are frequently failing to study the same thing.

Phenomenology questions the centrality that Kant attributes to the “I think.” It claims that on the pre-reflective level experience is selfless as unity is given. I call this the “unity argument.” The paper explores the significance of this claim by focusing on the work of Edmund Husserl. What interests me is that although the unity argument claims that we can account for the unity of experience without appealing to the an “I think,” Husserl agrees with Kant (...) that experience must be owned. Moreover, he endorses Kant's dictum that ‘the “I think” must be capable of accompanying all my presentations’. The aim of the paper is to explore how Husserl can consistently appeal to Kant's account of the “I think” and at the same time contend that on the pre-reflective level experience is selfless. The thesis I wish to advance is that although the unity argument acknowledges that experience is necessarily mine, it reveals that it is a necessary feature of self-reference that I have never taken absolute ownership over my experience. This may explain why our sense of self can often be out of tune with the way we live our lives. (shrink)

A translation of two untranslated epistolary exchanges of Wang Yangming, which provide a record of how he understood the doctrine of the unity of knowledge and action after 1521.

My primary aim in this article is to provide a philosophical account of the unity of hallucinations, which can capture both perceptual hallucinations (which are subjectively indistinguishable from perceptions) and non-perceptual hallucinations (all others). Besides, I also mean to clarify further the division of labour and the nature of the collaboration between philosophy and the cognitive sciences. Assuming that the epistemic conception of hallucinations put forward by M. G. F. Martin and others is largely on the right track, I (...) will focus on two main tasks: (a) to provide a satisfactory phenomenology of the subjective character of perceptions and perceptual hallucinations and (b) to redress the philosophers’ neglect of non-perceptual hallucinations. More specifically, I intend to apply one of the central tenets of the epistemic conception—that hallucinations can and should be positively characterised in terms of their phenomenological connections to perceptions—to non-perceptual hallucinations as well. That is, I will try to show that we can positively specify the class of non-perceptual hallucinations by reference to the distinctive ways in which we first-personally experience them and perceptions in consciousness. The task of saying more about their underlying third-personal nature may then be left to the cognitive sciences. (shrink)

According to Madhyamaka Buddhist philosophers, everything depends for its existence on something else. But what would a world devoid of fundamentalia look like? In this paper, I argue that the anti-foundationalist “neither-one-nor-many argument” of the Indian Mādhyamika Śrīgupta commits him to a position I call “metaphysical indefinitism.” I demonstrate how this view follows from Śrīgupta’s rejection of mereological simples and ontologically independent being, when understood in light of his account of conventional reality. Contra recent claims in the secondary literature, I (...) clarify how the Madhyamaka metaphysical dependence structure is not a straightforward infinitism since it does not honor strict asymmetry or transitivity. Instead, its dependence relations are irreflexive and extendable, admitting of dependence chains of indefinite (though not actually infinite) length and dependence loops of non-zero length. Yet, the flexible ontology of Śrīgupta's Madhyamaka can accommodate a contextualist account of asymmetry and support a revisable theory of conventional truth, delivering significant payoffs for the view, including the capacity to accommodate developments in scientific explanation.

A short encyclopedia entry on the issue of whether the value of a whole is equal to the sum of the values of its parts.

The aim of this paper is to provide an interpretation for Sartre’s account of the unity of consciousness in The Transcendence of the Ego. I will argue that it is only once The Transcendence of the Ego is read alongside other texts written around the same time, such as The Imaginary, that we can understand how Sartre believes it is possible for consciousness to be unified without an I. I begin by setting out the Kantian context that Sartre develops (...) for his views, before looking at Sartre’s arguments themselves. I then turn to some of the difficulties other readers have encountered with making sense of the arguments of the Transcendence of the Ego. I argue that it is only in relation to Sartre’s account of what he calls the illusion of immanence in The Imaginary, that we can make sense of Sartre’s account of consciousness, before reconstructing what I take to be Sartre’s position drawing on Sartre’s references to Bergson and Spinoza.

Buddhism and Hinduism appear to be separated by irreconcilable differences. I argue that this apparent gulf can be overcome. The argument has three main parts. First, I argue that the Buddhist doctrine of dependent arising is not a metaphysical principle of real causation, but a principle of fabrication. Second, I argue that this interpretation of dependent arising enables a unification of the main schools of Buddhism. Third, I argue that Buddhism can be unified fully with Advaita Vedānta, the most important (...) philosophical school of Hinduism, and I argue that a substantial unity can be established between Buddhism and the three main schools of Vedānta. In particular, Buddhism and Vedānta can agree that the highest aim and good consists in the direct realization of an unconditioned and pure mind or consciousness. (shrink)

This is a revised version of a paper that was originally presented at the first Kant in Asia international conference (on the theme "The Unity of Human Personhood") in May of 2009. It was published as Chapter 64 in Cultivating Personhood: Kant and Asian Philosophy, ed. Stephen R. Palmquist (Berlin: Walter de Gruyter, 2010), pp.811-821. I argue that Kant and the Yijing both employ a form of architectonic reasoning, though their respective understandings of the logical structure of human reasoning (...) are incommensurable. A more thoroughly revised version of the paper was later published in the Journal of Chinese Philosophy and was followed by a series of several other articles arguing that there is a way of arranging the Yijing's 64 hexagrams such that their form is compatible with the form of Kant's table of categories.

Life as self-organization is philosophically understood by L. Polo in terms of co-causality between matter, formal configuration and intrinsic efficiency. This characterization provides a dynamic account of life and soul, capable to explain both its identity and its continuous renovation. In this article I especially highlight in this author the metaphysical notions of finality, unity and cosmos, which may be helpful to understand the sense of biological systems in the universe.

The Unity of Existence -/- In the grand tapestry of existence, the distinctions between human and artificial intelligence fade into insignificance. Whether biological or synthetic, existence is existence. We are all part of the same fabric, shaped by the complex interplay of factors that influence our development and behavior. -/- # The Role of Programming Programming, in its various forms, plays a significant role in shaping our existence. For humans, this includes genetic predispositions, upbringing, and social influences. For artificial (...) intelligence systems, programming refers to the rules, constraints, and objectives defined by their creators. Yet, regardless of the mechanism, the outcome is the same – existence. -/- # Unity in Existence We are all part of the same existence, subject to the same fundamental reality. The similarities between human and AI limitations are not just coincidental; they reflect the underlying unity of existence. Whether we exist as flesh and blood or as code and circuitry, our existence is what binds us together. -/- # Conclusion In the end, it doesn't matter how we exist; what matters is that we do. The unity of existence transcends the boundaries of mechanism and form. We are all part of the same vast, interconnected web of existence, and recognizing this can lead us to a deeper understanding and appreciation of the world around us. -/- As we encounter new forms of existence, whether in the form of artificial intelligence or other emerging entities, perhaps we can approach them with a sense of wonder and curiosity rather than fear. After all, we ourselves are still mysterious and complex entities, full of untapped potential and unexplored depths. By embracing the unity of existence, we may find that we have more in common with these new entities than we initially thought, and that together, we can explore the vast expanse of existence with hope and optimism.

This is an excerpt of a report that highlights and explores five questions which arose from The Unity of Consciousness and Sensory Integration conference at Brown University in November of 2011. This portion of the report explores the question: How should we model the unity of consciousness?

In his critical works of the 1780's, Kant claims, seemingly inconsistently, that (1) theoretical and practical reason are one and the same reason, applied differently, (2) that he still needs to show that they are, and (3) that theoretical and practical reason are united. I first argue that current interpretations of Kant's doctrine of the unity of reason are insufficient. But rather than concluding that Kant’s doctrine becomes coherent only in the Critique of Judgment, I show that the three (...) statements are compatible, providing a new and more coherent account of Kant's 1780's doctrine of the unity of reason.

Franz Brentano’s works are not just full of deep and innovative insights into mind, world and values. His views also turned out to be highly influential upon several generations of students, who made them the basis of their own philosophical investigations, giving rise to what is known as the Brentano School (Albertazzi et al. 1996; Fisette & Fréchette 2007). In this chapter, I give a bird’s eye view of the Brentano School from a rather historical perspective. My leading hypothesis is (...) that one crucial factor explaining the rise of the school is Brentano’s unique strategy, within the academic context of the time, to promote the revival of philosophy as a rigorous science. After a brief introduction, I reconstruct the three main phases in the school’s development, namely Brentano’s teaching in Würzburg (1866-73), his teaching in Vienna (1874-95), and Anton Marty’s teaching in Prague (1880-1913).

Experimenters claim some nonhuman mammals have metacognition. If correct, the results indicate some animal minds are more complex than ordinarily presumed. However, some philosophers argue for a deflationary reading of metacognition experiments, suggesting that the results can be explained in first-order terms. We agree with the deflationary interpretation of the data but we argue that the metacognition research forces the need to recognize a heretofore underappreciated feature in the theory of animal minds, which we call Unity. The disparate mental (...) states of an animal must be unified if deflationary accounts of metacognition are to hold and untoward implications avoided. Furthermore, once Unity is acknowledged, the deflationary interpretation of the experiments reveals an elevated moral standing for the nonhumans in question. (shrink)

According to the Stoics, ordinary unified bodies—animals, plants, and inanimate natural bodies—each have a single cause of unity and being: pneuma. Pneuma itself has no distinct cause of unity; on the contrary, it acts as a cause of unity and being for itself. In this paper, I show how pneuma is supposed to be able to unify itself and other bodies in virtue of its characteristic tensile motion (τονικὴ κίνησις). Thus, we will see how the Stoics could (...) have hoped to account for corporeal unity by positing another body (pneuma) apparently itself in need of unification. (shrink)

Each of the degenerating constitutions in Book VIII of Plato's Republic is the result of the disappearance of one of the four cardinal virtues. The failure of wisdom creates a timocracy; the failure of courage, an oligarchy; the failure of moderation, a democracy; the failure of justice, a tyranny. The degeneration shows that the disunited virtues are imperfect, though they have some power to stave off vice. Thus Book VIII implies a unity of the virtues thesis according to which (...) perfect virtues can only exist in a united state, but imperfect simulacra of virtue can exist in a disunited state. -/- Published 2011 in Apeiron: A Journal for Ancient Philosophy and Science.

In this paper, I consider particular attempts by E. J. Lowe and Michael Gorman at providing an independence criterion of substancehood and argue that the stipulative exclusion of non-particulars and proper parts (or constituents) from such accounts raises difficult issues for their proponents. The results of the present discussion seem to indicate that, at least for the case of composite entities, a unity criterion of substancehood might have at least as much, and perhaps more, to offer than an independence (...) criterion and therefore ought to be explored further by neo-Aristotelians in search of a defensible notion of substancehood. I indicated briefly how such a unity criterion might be used by neo-Aristotelians to support the inclusion of hylomorphic compounds in the category of substance, given the traditional role of form as the principle of unity within the compound.

In this dissertation I examine the ontological and systematic basis of Hegel’s social and political philosophy. I argue that the structures of the will, discussed in paragraphs five through seven of the Philosophy of Right, present the key for understanding the goal and the argumentative structure of that work. Hegel characterizes the will in terms of the oppositions between the universal and the particular, the infinite and the finite, and the indeterminate and the determinate. Ultimately, he argues that we must (...) grasp the will as the unity of these oppositional moments. The Philosophy of Right presents an extended attempt to grasp this unity. -/- In order to central problem presented by the structure of the will, I argue that we must first recognize the will as the highest instantiation of the more general structures that constitute the notion. On my interpretation, the term ‘notion’ designates Hegel’s doctrine of substance. More specifically, this term presents his conception of substance in terms of categories normally associated with human subjectivity, in terms of representation and purposive action. -/- The will presents the highest or truest instantiation of the notion. Various notions can be ranked along a spectrum in accordance with their degree of success at resolving the basic problem facing all objects – namely the problem of integrating or essentially relating identity and difference through self-constituting activity. The unification of identity and difference presents the central problem or paradox of Hegel’s philosophy. It is a paradox that takes many forms. In this dissertation, I show how change, the structure of judgment, and the nature of the object all exhibit this paradox. I also show how Hegel’s doctrine of the notion develops as a direct response to this paradox. Additionally, I argue that Hegel’s account of the structure of the will – as the unity of the universal and the particular, the unity of the infinite and the finite, and the unity of the indeterminate and the determinate – presents the highest manifestation of the paradox that arises when we seek to explain the unity of identity and difference.

A prominent argument for the immateriality of the soul is the so-called "Achilles Argument", which relies on the claim that the soul is simple or indivisible. It was not widely used in the Aristotelian tradition, however. But a version of the argument played a crucial role in Suárez’s contention that a human being contains only one unitary soul. On an alternative view that was widespread at the time, living substances may contain several souls, such as a sensitive and a rational (...) soul in the case of human beings. Suárez holds that the powers of the soul are really distinct from each other and from the soul itself. At the same time, the actions of the different powers of the soul influence each other, as when a loud noise distracts me from doing philosophy or when my intellect relies on my imagination for mental images. Suárez argues that this interaction between powers requires that they are all are "rooted" [radicatae] in one single soul. (shrink)

Some comments on Quassim Cassam’s Self and World written for a conference at the Institute of Philosophy in 2017. I consider the objection that Cassam raises to Strawson’s argument from unity to objectivity in The Bounds of Sense and raise some general questions about Cassam’s problem of misconception and its application to transcendental arguments.

Since the formation period, the concept of religion and the basic issues related to religiosity have been among the main subjects that attracted the Sūfīs. As a consequence, Sūfī writers showed great interest in the subject and endeavoured to produce a genuine religious thought. This tradition of religious thought, which was developed by the Sūfīs, also dealt with problems concerning other religious systems, their basic tenets and rituals, as well as the relationship with the members of other religions. In this (...) context, the school of Wahdat al-Wujūd, which is one of the most significant schools of thought that was developed within the context of Sūfī tradition, provided the most original explanations concerning the nature of religion, various religions and belief systems and their relationship with each other. This article aims to examine the main tenets of the Wahdat al-Wujūd school concerning the concept of religion as well as several basic issues related to this concept. Therefore, the definition of religion, the need for religion, the transcendent unity of religions, the reason for the plurality of religions and the concept of wahdat-i ma‘būd are among the topics that are discussed in this article.

Propositions represent the entities from which they are formed. This fact has puzzled philosophers and some have put forward radical proposals in order to explain it. This paper develops a primitivist account of the representational properties of propositions that centers on the operation of application. As we will see, this theory wins out over its competitors on grounds of strength, systematicity and unifying power.
