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)

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)

This article develops a teleodynamic field architecture as a non-reductive account of unity. Beginning with Leibniz’s perspectival monadology, it reconstructs unity as internally constituted rather than mechanically imposed. It then turns to Guenther’s poly-contextural logic, which replaces binary ontology with stratified logical domains, and to Whitehead’s process philosophy, which situates unity within evental becoming. Each of these approaches contributes a decisive structural insight, yet each leaves a fundamental dimension underdetermined: Leibniz lacks genuine feedback, Guenther lacks dynamic curvature, (...) and Whitehead lacks a formal account of recursive stabilization. The proposed teleodynamic model integrates these insights within a hierarchically structured and recursively closed system composed of transformation, regulation, and field curvature. Operators generate semantic dynamics, regulatory mechanisms constrain and modulate transformation, and curvature structures define global stability landscapes. Crucially, transformation feeds back into curvature, yielding attractor formation within a dynamically modulated field. On this basis, pansemantism is reformulated as a field ontology: meaning is neither substance nor mere representation but the geometrical stabilization of difference under recursive modulation. Unity thus emerges not from metaphysical foundation, logical imposition, or pure process, but from recursive field organization. (shrink)

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)

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.

Standard accounts of object perception force us to choose between the unity of objects and the particularity of objects. The unity of objects is explained in terms of general, repeatable representations and a mental act of predication that binds those representations. The particularity of objects is explained in terms of particular, unrepeatable representations and a pre-predicational mode of perceptual consciousness. Generalists argue that particularists cannot explain the structure of perception while particularists argue that generalism makes perception indifferent to (...) the objects themselves. Here, I show how Susanna Schellenberg’s capacitism can capture the motivations for both views. According to capacitism, perception is the result of exercises of perceptual capacities to discriminate concrete perceptual particulars. The trouble is that Schellenberg’s capacitism struggles to explain the structure of object perception without resorting to a further contribution from non-perceptual capacities. I propose that these problems can be avoided by positing a capacity to discriminate unity. Successful exercises of this capacity result in a representation of an object bound with its properties and make us directly aware of an object’s unity. (shrink)

Grounding, understood as a primitive posit operative in contexts where metaphysical dependence is at issue, is not able on its own to do any substantive work in characterizing or illuminating metaphysical dependence---or so I argue in 'No Work for a Theory of Grounding' (Inquiry, 2014). Such illumination rather requires appeal to specific metaphysical relations---type or token identity, functional realization, the determinable-determinate relation, the mereological part-whole relation, and so on---of the sort typically at issue in these contexts. In that case, why (...) posit 'big-G' Grounding in addition to the 'small-g' grounding relations already in the metaphysician's toolkit? The best reasons for doing so stem from the Unity argument, according to which the further posit of Grounding is motivated as an apt unifier of the specific relations, and the Priority argument, according to which Grounding is needed in order to fix the direction of priority of the specific relations. I previously considered versions of these arguments, and argued that they did not succeed; in two papers, however, Jonathan Schaffer aims to develop a better version of the Unity argument, and offers certain objections to my reasons for rejecting the Priority argument. Here I consider these new arguments for Grounding. (shrink)

The idea that moral virtues form some sort of “unity” has received considerable attention from virtue theorists. In this paper, I argue that the possibility of unity among intellectual virtues has been wrongly overlooked. My approach has two main components. First, I work to distinguish the variety of different views that are available under the description of a unity thesis. I suggest that these views can be categorised depending on whether they are versions of standard unity (...) or of strong unity. Standard unity claims that the possession of one virtue implies possession of all the others. Strong unity claims that the virtues are, in some sense, all the same thing. By exploring what these different versions of unity would look like when applied to intellectual virtues, I aim to provide a menu of options for future work in virtue epistemology. I then develop and defend one of these options in more detail, arguing that the initially less plausible strong unity has merit when applied to the intellectual sphere. In these two ways, I aim to show that the possibility of unity among the intellectual virtues is deserving of serious consideration. (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)

The problem of the unity of the proposition asks what binds together the constituents of a proposition into a fully formed proposition that provides truth conditions for the assertoric sentence that expresses it, rather than merely a set of objects. Hanks’ solution is to reject the traditional distinction between content and force. If his theory is successful, then there is a plausible extension of it that readily solves the Frege–Geach problem for normative propositions. Unfortunately Hanks’ theory isn’t successful, but (...) it does point to significant connections between expressivism, unity, and embedding. (shrink)

The Unity Argument states that the ability to think of one's perceptions as perceptions of objects in the weighty sense is necessary for unity of consciousness. A distinction is drawn between two versions of the Unity Argument. The first turns on the idea that unity of consciousness involves what P. F. Strawson calls ’transcendental’ self‐consciousness. The second turns on the idea that unity of consciousness involves ’personal’ self‐consciousness.

Tim Bayne draws on philosophy, psychology, and neuroscience in defence of the claim that consciousness is unified. He develops an account of what it means to say that consciousness is unified, and then applies this account to a variety of cases - drawn from both normal and pathological forms of experience - in which the unity of consciousness is said to break down. He goes on to explore the implications of the unity of consciousness for theories of consciousness, (...) for the sense of embodiment, and for accounts of the self. The Unity of Consciousness draws on a wide range of findings within philosophy and the sciences of the mind to construct an account of the unity of consciousness that is both conceptually sophisticated and scientifically informed.

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.

The Unity of Reason is the first major study of Kant's account of reason. It argues that Kant's wide-ranging interests and goals can only be understood by redirecting attention from epistemological questions of his work to those concerning the nature of reason. Rather than accepting a notion of reason given by his predecessors, a fundamental aim of Kant's philosophy is to reconceive the nature of reason. This enables us to understand Kant's insistence on the unity of theoretical and (...) practical reason as well as his claim that his metaphysics was driven by practical and political ends. Neiman begins by discussing the historical roots of Kant's conception of reason, and by showing Kant's solution to problems which earlier conceptions left unresolved. Kant's notion of reason itself is examined through a discussion of all the activities Kant attributes to reason. In separate chapters discussing the role of reason in science, morality, religion, and philosophy, Neiman explores Kant's distinctions between reason and knowledge, and his difficult account of the regulative principles of reason. Through examination of these principles in Kant's major and minor writings, The Unity of Reason provides a fundamentally new perspective on Kant's entire work. (shrink)

天人合一，不是人的理想， 而是宇宙的必然。 当我们仰望星空， 无数光年之外的“道”， 正于我们心中闪烁。 The unity of Heaven and humanity is not humanity’s dream, but the universe’s inevitability. When we gaze upon the stars, the Dao that shines across galaxies also flickers within our hearts. 一息一念，皆为宇宙之声； 一生一灭，皆在“道”之流转。 回归，不是退隐， 而是与万物同频的觉醒。 Each breath, each thought, is the voice of the cosmos; each birth and death, a pulse in the Dao’s unfolding. To return is not to retreat— it is to awaken into resonance with all things.

At least since Russell’s influential discussion in The Principles of Mathematics, many philosophers have held there is a problem that they call the problem of the unity of the proposition. In a recent paper, I argued that there is no single problem that alone deserves the epithet the problem of the unity of the proposition. I there distinguished three problems or questions, each of which had some right to be called a problem regarding the unity of the (...) proposition; and I showed how the account of propositions formulated in my book The Nature and Structure of Content [2007 Oxford University Press] solves each of these problems. In the present paper, I take up two of these problems/questions yet again. For I want to consider other accounts of propositions and compare their solutions to these problems, or lack thereof, to mine. I argue that my account provides the best solutions to the unity problems. (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 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)

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.

This paper offers a novel view of unity in neuroscience. I set out by discussing problems with the classical account of unity-by-reduction, due to Oppenheim and Putnam. That view relies on a strong notion of levels, which has substantial problems. A more recent alternative, the mechanistic “mosaic” view due to Craver, does not have such problems. But I argue that the mosaic ideal of unity is too minimal, and we should, if possible, aspire for more. Relying on (...) a number of recent works in theoretical neuroscience—network motifs, canonical neural computations and design-principles—I then present my alternative: a “flat” view of unity, i.e. one that is not based on levels. Instead, it treats unity as attained via the identification of recurrent explanatory patterns, under which a range of neuroscientific phenomena are subsumed. I develop this view by recourse to a causal conception of explanation, and distinguish it from Kitcher’s view of explanatory unification and related ideas. Such a view of unity is suitably ambitious, I suggest, and has empirical plausibility. It is fit to serve as an appropriate working hypothesis for 21st century neuroscience. (shrink)

This paper concerns the role that reference to subjects of experience can play in individuating streams of consciousness, and the relationship between the subjective and the objective structure of consciousness. A critique of Tim Bayne’s recent book indicates certain crucial choices that works on the unity of consciousness must make. If one identifies the subject of experience with something whose consciousness is necessarily unified, then one cannot offer an account of the objective structure of consciousness. Alternatively, identifying the subject (...) of experience with an animal means forgoing the conceptual connection between being a subject of experience and having a single phenomenal perspective.

Renewed worries about the unity of the proposition have been taken as a crucial stumbling block for any traditional conception of propositions. These worries are often framed in terms of how entities independent of mind and language can have truth conditions: why is the proposition that Desdemona loves Cassio true if and only if she loves him? I argue that the best understanding of these worries shows that they should be solved by our theory of truth and not our (...) theory of content. Specifically, I propose a version of the redundancy theory according to which ‘it is true that Desdemona loves Cassio’ expresses the same proposition as ‘Desdemona loves Cassio’. Surprisingly, this variant of the redundancy theory treats ‘is true’ as an ordinary predicate of the language, thereby defusing many standard criticisms of the redundancy theory. (shrink)

Among the most promising options for vindicating Oppenheim and Putnam’s unity of science hypothesis is the ‘Mentaculus’ of Albert and Loewer. I assess whether this promise can be borne out. My focus is on whether the Mentaculus can deliver what Oppenheim and Putnam call the ‘unity of laws’: the reduction of special science laws to the laws of fundamental physics. I conclude that although the Mentaculus may support a fairly strong form of reductionism, it falls short of upholding (...) the unity of laws. (shrink)

Much recent attention has been paid to Kant’s account of the unity of space in the Critique of Pure Reason, not least because of the significant implications of that view for other key critical-period doctrines. But far less attention has been paid to the development of Kant’s account of the unity of space. This paper aims to offer a systematic account of Kant’s pre-critical account of the unity of space. On the view presented herein, Kant’s early account (...) of the unity of space is deeply rooted in his pre-critical cosmological views. In particular, I argue that Kant sees the unity of space as grounded in the cosmological unity of the world of substances, which is itself rooted in the divine conservation of all substances in relations of mutual causal dependence. I contend that the seeds of this view are present in the late 1740s and 1750s, but that this view receives its fullest and most complete expression in the 1770 Inaugural Dissertation. The final section of the paper considers the fate of Kant’s pre-critical account of the unity of space. I contend that the theory is excluded from the Critique of Pure Reason in light of the strict epistemological strictures adopted in that text. But considerable textual evidence shows that Kant continues to aver the theory throughout the 1770s and 1780s in the looser epistemic context of his lectures. I contend, then, that this theory is not abandoned at all. Rather, like Kant’s 1763 proof of the existence of God, it is epistemically demoted: it is Kant’s preferred view, but one that falls short of the demanding epistemic standards of the critical philosophy.

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.

Even though the virtues may be interconnected, it seems obviously possible to have one of the virtues without having them all. Some have defended the unity thesis against this concern by arguing that the virtues are still unified in their ideal forms. The problem with this defense is that it simply admits that the unity thesis, as traditionally conceived, is mistaken, taking the unity of the virtues to be limited to the ideal case. In this paper, I (...) outline a blueprint for how the ideal virtue response can be used to defend the original unity thesis. (shrink)

Two kinds of behavioral dissociation are distinctive of the so-called split-brain phenomenon and first motivated the thought that split-brain consciousness might be structurally dual, with each cerebral hemisphere associated with a distinct stream or sphere of consciousness. One of these behavioral dissociations, however, tends to diminish in observed frequency and severity over time. What implications does this have for the debate over the structure of split-brain consciousness? Some neuroscientists have recently argued that motoric information remains interhemispherically integrated and that this (...) shows that split-brain consciousness is unitary after all. This paper argues that an account of conscious unity grounded in that sort of integration would look quite different from the most familiar accounts of conscious unity. It proposes a new kind of unity relation that might persist after split-brain surgery and then considers whether this relation is a genuine kind of conscious unity. (shrink)

This study explored the factors influencing church and retention of members within the Lagos East Baptist Conference (LEBC) in Nigeria. It examined how these findings are capable of informing the ecumenical witness of churches in South Africa, particularly in light of the theological insights of the Belhar Confession. The investigation was motivated by shared challenges in Baptist and Reformed ecclesial communities, including declining congregational vitality, intergenerational disconnection and a diminished public theological presence. This study used a mixed-method approach in the (...) form of surveys, interviews and document analyses and sought to understand the reasons for the decline in congregation and the capacity of the church to preserve congregational vitality in the 21st century. The findings revealed that although the LEBC churches remain resilient as a result of their discipleship activities, small-group frameworks and various organisational church activities, demonstrating an 89% retention rate among small-group participants, the study identified four critical challenges to retention in the form of leadership succession, migration of youth, socio-economic factors and differing opinions on the issues of faith. Most importantly, the unity of the LEBC associations encouraged cooperative problem solving, enhanced retention of a shared missional identity and strengthened resource retention, all of which made retention of members possible. Contribution: The study advances seven principal recommendations for policy reform, ecumenical collaboration and leadership formation, proposing that unity functions not merely as a theological aspiration but also as an operative mechanism for ecclesial resilience. It concludes that lessons from LEBC experience could be beneficial to South Africa, where churches are facing challenges of declining attendance, shifting generations and reclaiming an ecumenical witness in the midst of socio-political polarisation. Moreover, the unity of African church communities as a theological and strategic imperative could also be a measure of the capacity of African churches to realise the Belhar Confession. (shrink)

This paper offers a new interpretation of the unity of the human soul’s parts in De Anima II.3, drawing on the mathematical notion of dimension. Dimensionality, understood as an intrinsic property that parameterises a system’s complexity by the number of its independent yet ordered parameters, provides a suitable framework for explaining the unity of the tripartite human soul. The nutritive, the perceptual, and the intellectual parts emerge as three definitionally distinct yet operationally ordered dimensions of a human being. (...) Though anachronistic, this dimensional account is philosophically fruitful: it effectively unifies three structural features of the soul’s parts – serial order, potential containment, and teleological subordination – identified in recent scholarship (Johansen 2012, 2014; Corcilius 2015, 2023, 2025).

According to the Aristotelian account of substantial change, that is, the corruption of one substance and the generation of another, prime matter must be found at the starting and at the end point of change, as that which persists throughout the change. But knowing that matter remains as the substrate of change tells us little about the nature of this matter, which constitutes both the corrupted substance and the new generated substance. Among the questions we can ask about its nature (...) are whether prime matter is an entity of its own apart from form; whether it is one in all those individual material substances or is somehow divided or partitioned into different parts. Early commentaries on the Physics and Metaphysics were interested in precisely these questions about the unity and divisibility of prime matter and about what kind of unity this may be. This article aims to investigate how authors from the English commentary tradition in the period 1250–1270 answered these questions. (shrink)

In this work, I discuss the concept of existential feelings recently developed by Matthew Ratcliffe in three steps. First, I examine the concept, taking into account its initial formulation and internal aspects. After presenting how this affective dimension resists the traditional body/cognition dichotomy in classical philosophy of emotion, I draw attention to the inconspicuous nature of these feelings and its structuring role in our intentional life. While it includes bodily elements that can be identified and described, its significance becomes most (...) apparent when its proper functioning is disrupted. The unfolding of an ordinary experience, its “normality”, thus depends on a level of habituality and normalcy in which these feelings are not manifest. Second, I analyze the assumption that cases of illness provide us with a lens through which to access this tacit dimension. In line with Ratcliffe, I argue that psychiatric disorders offer a privileged standpoint for grasping this affective-structural dimension of our intentional life. However, despite their apparent diversity, I argue that pathological existential feelings must share something if they are to be clinically relevant. So, third and finally, I argue for a kind of unity underlying pathological existential feelings in psychiatric disorders. I propose that a distinctive sense of doubt can be meaningfully attributed to the lived experience of these conditions. The implications of this notion for a phenomenologically informed psychiatry are also explored. (shrink)

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.

A weak unity thesis about epistemic virtues holds that there is a core epistemic value – true belief – and that processes, traits, or actions are epistemic virtues by virtue of their relations with this core value. According to veritistic unitarianism, justification is a distinct epistemic value from truth but derives its value from that of true belief. This is explicit in reliabilism and implicit in many varieties of foundationalism and coherentism. Deontological evidentialism rejects veritistic consequentialism but has trouble (...) accounting for evidence‐gathering virtues. The claim that “pragmatic” epistemic virtues are unrelated to truth is examined but found unpersuasive or readily accommodated with minor tweakings of the veritistic perspective. (shrink)

Chapter 3 is the first of six on sensibility and its relation to the understanding. Its focus is sensation, intuition, and appearance. It also examines why Kant deemed pure intuition necessary to sensibility as such, without regard to the conceptual and cognitive uses to which it may be put. To this end, it is argued that given sensations alone, nothing like a unified sensibility would be possible, i.e., there would be no capacity to represent all possible affections of sense as (...) a single, homogeneous manifold, united in one and the same consciousness. Pure intuition is therefore just as essential to sensibility as sense affections because only it can provide for such a _unity of sensibility_, a unity that proves to be nothing else than a prediscursive, precategorial expression of the original synthetic unity of apperception.

I defend the view that there are organic unities mainly by presenting examples of organic unities. I also defend the view against two objections. The first objection appeals to the notion of an evaluatively incomplete state of affairs. The second objection holds that the intrinsic value of a state of affairs can be different in different contexts. I argue that neither objection provides a compelling reason for rejecting these examples.

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.

The manifest fact of experiential unity—namely, that a single experience often seems to be composed of multiple features and multiple objects—was lodged as a key objection to the Buddhist no-self view by Nyāya philosophers in the classical Indian tradition. We revisit the Nyāya-Buddhist debate on this issue. The early Nyāya experiential unity arguments depend on diachronic unification of experiences in memory, but later Nyāya philosophers explicitly widened the scope to incorporate new unity arguments that invoke synchronic unification (...) in experiences. We argue that classical responses to this objection in the Buddhist traditions are not satisfactory. We offer a new solution on behalf of the Buddhists, with some help from cognitive sciences. We argue that there are different kinds of experiential unity and that, once we distinguish between these kinds, the Nyāya argument becomes difficult to sustain. (shrink)

The incompetence of the interpretation of the unity and fight of oppositions’ statement as the theoretical basis for the development and functioning of the confrontational viewpoint is grounded in the article. The idea is researched that the unity and fight as well as other pared and polar categories of the dialectics are inseparable and comprise the moments of the unity-equality of the unity and fight of oppositions that is the dialectic controversy. Place of concepts “unity” (...) and “fight” in the system of reflexive determinations of essence are noted. The general sequence of the last appears in a kind an identity (unity) is a difference–opposition–fight–contradiction. Thus, contradiction shows by itself not only the final category of the indicated row but also all previous in relation to it essence moments, degrees of its becoming (to development). It is especially marked on general and necessary character of unity fight of the same oppositions. Speech goes that, as well as opposition, unity and fight, show by itself such category structure of mind, which in different forms is always reproduced in the acts of his activity. Question only in that or it is realized or not. It is underlined in the article, that a concept “unity” and “fight” (oppositions) in the interrelation find out reflexive nature: unity is a that fight, but in its given, specification, form, and, opposite, a fight is that their unity, but through a mutual layingon them mutually exclusive, contradicting each other. On the basis of it the conclusion is drawn that unity is a concept which makes sense only in relation to a fight, as well as the fight loses every sense out of unity, and their isolation (disconnection) is possible only in our subjective reflection: that in every special case sets to the object of consideration is unity or fight.

Aristotle’s priority relation exhibits a puzzling disunity: Aristotle argues for priority in being relations in multiple ways, and none of the arguments he gives would succeed in justifying the full range of cases he endorses. While questions about how to unify Aristotle’s claims and arguments about priority have received sustained scholarly attention, questions about what could motivate Aristotle to accept this prima facie disunified set of cases have received less focused attention. This chapter explores the textual resources a causal view (...) of priority offers us to address this question about the motivation for Aristotle’s views, and argues that these resources point us in the direction of a philosophically interesting account of the unity of the priority relation – one according to which different cases count as prior precisely because of their differences, not in spite of those differences.

Three types of unity that self-governing systems possess are discussed. The first is the synthetic unity attained when information drawn from incommensurate sources is mapped into a common frame of reference. The second is the unity of voice—or “univocity”—attained when a set of separate, potentially conflicting informational streams is united into a single collective voice. The third is the dynamical unity achieved when the parts of a system operate under the command of a single voice. Peeling (...) back the curtain and looking at how the personal point of view arises, and how the unities that are given introspectively are generated by work that the brain does dispels the mystery that is at least partly behind the imaginative pictures of self as mental substance or soul-stuff.

In the context of a critique of James Conant’s (2016) important new reading of the main argument of the Deduction, I present my current, most detailed interpretation of the well-known Leitfaden passage at A79, which in my view has been misinterpreted by a host of prominent readers. The Leitfaden passage is crucial to understanding the argument of, not just the so-called Metaphysical Deduction, but also the Transcendental Deduction. This new account expands and improves upon the account of the Leitfaden I (...) gave in Chap. 5 of Kant’s Deduction From Apperception. While I agree with the core of Conant’s critique of what he calls the ‘layer-cake’ reading of the Deduction argument, in this new account I make clearer my position on why the unity of judgement, in which concepts and intuitions are a priori synthetically unified, is wholly determined in virtue of the unity of apperception as the unitary function of the understanding, without this leading to a strong form of conceptualism such as that of Conant and others.

This volume presents fourteen essays by leading figures in the fields of ancient philosophy and contemporary metaphysics, discussing Aristotle's theory of the unity and identity of substances, a topic that remains at the center of metaphysical enquiry. The contributors examine the nature of essences, how they differ from other components of substance, and how they are related to these other components. The central questions discussed are: What does Aristotle mean by "potentiality" and "actuality?" How do these concepts explicate matter (...) and form, and how are they related to the actuality of a substance? What is the role of actuality in accounting for the unity and identity of substance? These questions are crucial to an understanding of the unity of composite substances and their identity over time. The aim of the volume is both exegetical and philosophical: to give answers to central problems in Aristotle's metaphysics, and also to stimulate further investigation of the problems defined and the controversies embodied.

In "The Disunity of Consciousness," Gerard O'Brien and Jon Opie argue that human consciousness is not synchronically unified. They suggest that the orthodox conception of the unity of consciousness admits of two readings, neither of which they find persuasive. According to them, "a conscious individual does not have a single consciousness, but several distinct phenomenal consciousnesses, at least one for each of the senses, running in parallel." They call this conception of consciousness the _multi-track account. I make three points (...) in reply: (1) O'Brien and Opie's characterization of the orthodox conception of the unity of consciousness is problematic; (2) their arguments in support of the multitrack account are unpersuasive; and (3) the phenomenon of intersensory integration suggests that O'Brien and Opie are wrong to claim that "the only sense in which it is correct to talk of a 'unified' consciousness (...) is that in which the representational contents of the various components coincide.".

ABSTRACT The connection between the unity of God and the multiplicity seen in the universe represents the central concern for the Sufi thinker, Muḥyī al-Dīn ibn ‘Arabī (d. 638/1240). It deeply affected the thought of the Southeast Asian mystic, Ḥamza Fanṣūrī (d. 1590?), and his alleged disciple, Shams al-Dīn al-Sumatra’ī (d. 1630). Traces of this idea, through its popularisation in the poems of Fanṣūrī, exert a powerful influence on the Indonesian intellectual topography to this day. This article investigates the (...) concept of unity and multiplicity, of the One expressed as the many in the phenomenal world, in Ibn ‘Arabī’s Fuṣūṣ al-ḥikam (Ringstones of Wisdom). Through a close textual reading of the chapters of Ādam (Adam) and Ibrāhīm (Abraham) and their various commentaries by the most influential followers of Ibn ‘Arabī, it concludes that the representation of ‘oneness of being’ (waḥdat al-wujūd), which was extensively taught by Fanṣūrī in Aceh, as an erasure of the God-Man divide, is untenable.

Whether or not intrinsic value is additively measurable is often thought to depend on the truth or falsity of G. E. Moore's principle of organic unities. I argue that the truth of this principle is, contrary to received opinion, compatible with additive measurement. However, there are other very plausible evaluative claims that are more difficult to combine with the additivity of intrinsic value. A plausible theory of the good should allow that there are certain kinds of states of affairs whose (...) intrinsic value cannot be outweighed by any number of states of certain other, less valuable, kinds. Such``non-trade-off'' cannot reasonably be explained in terms of organic unities, and it can be reconciled with the additivity thesis only if we are prepared to give up some traditional claims about the nature of intrinsic value.
