In this paper, I defend an unconventional mereological framework involving the doctrine of divine simplicity, to surmount a significant yet neglected dilemma resulting from that long-standing view of God as absolutely, and uniquely, simple. This framework establishes God as literally a part of everything—an “omni-part.” Although consequential for the many prominent religious traditions featuring divine simplicity, my analysis focuses on potential implications for an important formative issue in medieval Islamic philosophy. This problem of principality, with regards to metaphysical primacy (...) and importance, derives from Ibn Sīnā’s celebrated distinction between essence and existence, and involves determining which is genuinely, objectively, real. Instead of supporting the historically dominant opposing viewpoints advancing either the principality of existence or of essence (aṣālat al-wujūd/al-māhiyya), I claim that God as omni-part aids renewed defence of the majority rejected view which upholds the combined principality of existence and essence together. Additionally, my proposal reinforces various theological desiderata including divine omnipresence and God’s necessity across possible worlds, while also supporting new perspectives on Ibn ‘Arabi’s influential notion of waḥdat al-wūjūd, understood as the absolute unity of being.

Omnis Determinatio est Negatio. On Habermas, Myth, and Truth With his monumental genealogy of Western philosophy Jürgen Habermas delivers an achievement that is worthy of great praise. In carefully constructed arguments he presents in detail the close connection between, and the mutual indebtedness of, religion and philosophy as they developed in the West for more than two millennia. With regard to the current state of affairs he acknowledges that we should continue to engage with subjects such as purpose, meaningfulness, and (...) how to behave. He proposes that where religion is withdrawing, philosophy should take its place. In spite of its great merits, there are some fundamental shortcomings in the overall image Habermas wishes to convey. By suggesting that Western religion and philosophy have been the major driving forces not only of cognitive but also of ethical progress, he underestimates the moral value of pre-Socratic and other holistic world views that radically differ from the idiosyncratic Western one. For example, he perceives Homer’s mythological thinking as nothing but a primitive state of mind against which the ethical and intellectual progress of later developments could come to the fore. This paper proposes that we should give much more weight to the difference between the ‘cognitive’ and the ‘ethical’ than Habermas does. In principle, as a form of argumentative reasoning, philosophy belongs to the (cognitive) domain of truth. As such, it is not a suitable successor to religion. On the other hand, provided they operate primarily within their own domain – which is the domain of meaningfulness –, religion (in whatever form), literature and the arts, ancient myth, friendship, love, and humour may still be best equipped to sharpen our sense of justice and help us deal with feelings of moral disorientation and fragmentation.

Spinoza ’s letter of June 2, 1674 to his friend Jarig Jelles addresses several distinct and important issues in Spinoza ’s philosophy. It explains briefly the core of Spinoza ’s disagreement with Hobbes’ political theory, develops his innovative understanding of numbers, and elaborates on Spinoza ’s refusal to describe God as one or single. Then, toward the end of the letter, Spinoza writes: With regard to the statement that figure is a negation and not anything positive, it is obvious that (...) matter in its totality, considered without limitation [indefinitè consideratam], can have no figure, and that figure applies only to finite and determinate bodies. For he who says that he apprehends a figure, thereby means to indicate simply this, that he apprehends a determinate thing and the manner of its determination. This determination therefore does not pertain to the thing in regard to its being [esse]; on the contrary, it is its non-being [non-esse]. So since figure is nothing but determination, and determination is negation [Quia ergo figura non aliud, quam determinatio, et determinatio negatio est], figure can be nothing other than negation, as has been said. Arguably, what is most notable about this letter is the fate of a single subordinate clause which appears in the last sentence of this passage: et determinatio negatio est. That clause was to be adopted by Hegel and transformed into the slogan of his own dialectical method: Omnis determinatio est negatio. Of further significance is the fact that, while Hegel does credit Spinoza with the discovery of this most fundamental insight, he believes Spinoza failed to appreciate the importance of his discovery. The issue of negation and the possibility of self-negation stand at the very center of the philosophical dialogue between the systems of Spinoza and Hegel, and in this paper I will attempt to provide a preliminary explication of this foundational debate between the two systems. In the first part of the paper I will argue that the “determination is negation” formula has been understood in at least three distinct senses among the German Idealists, and as a result many of the participants in the discussion of this formula were actually talking past each other. The clarification of the three distinct senses of the formula will lead, in the second part of the paper, to a more precise evaluation of the fundamental debate between Spinoza and Hegel regarding the possibility of self-negation. In this part I will evaluate the validity of each interpretation of the determination formula, and motivate the positions of the various participants in the debate. (shrink)

Mereological nihilism says that there do not exist (in the fundamental sense) any objects with proper parts. A reason to accept it is that we can thereby eliminate 'part' from fundamental ideology. Many purported reasons to reject it - based on common sense, perception, and the possibility of gunk, for example - are weak. A more powerful reason is that composite objects seem needed for spacetime physics; but sets suffice instead.

Elselijn Kingma argues that, in cases of mammalian placental pregnancy, the foster (roughly, the post-implantation embryo/foetus) is part of the gravida (the pregnant organism). But she does not consider the possibility of proper overlap. I show that this generates a number of serious problems for her argument and trace the oversight to a quite general issue within the literature on biological individuality. Doing so provides an opportunity to pull apart and clarify the relations between some importantly distinct questions concerning organismality (...) and organismic parthood, and to identify the implications that this has for those who want to draw on this literature when making metaphysical or mereological arguments.

Is part of a perfectly natural, or fundamental, relation? Philosophers have been hesitant to take a stand on this issue. One reason for this hesitancy is the worry that, if parthood is perfectly natural, then the perfectly natural properties and relations are not suitably “independent” of one another. In this paper, I argue that parthood is a perfectly natural relation. In so doing, I argue that this “independence” worry is unfounded. I conclude by noting some consequences of the (...) naturalness of parthood. (shrink)

I argue that from a very weak recombination principle and plausible assumptions about the nature of parthood and location it follows that it's possible that the mereological structure of the material world and that of spacetime fail to correspond to one another in very radical ways. I defend, moreover, that rejecting the possibility of such failures of correspondence leaves us with a choice of equally radical alternatives. I also discuss a few ways in which their possibility is relevant to (...) various debates in metaphysics. (shrink)

In the following work we propose to incorporate the main feature of quantum mechanics, i.e., the concept of indiscernibility. To achieve this goal, first we present two models of set theories: a quasi-set theory and a non-antisymmetric mereology. Next, we show how specific objects of QST—m-atoms—can be defined within NAM. Finally, we introduce a concept of a parthood of indiscernibles and discuss its features in respect to standard notions of indiscernibles and within NAM.

According to a well known, yet controversial metaphysical thesis, Composition is Identity. Recently, Kris McDaniel has articulated and defended a related—and arguably more controversial—thesis, one he calls Parthood is Identity (PI). Roughly the view has it that a whole is, strictly and literally, identical to each of its parts considered individually. At first sight, the view seems rather implausible. However, McDaniel’s formulation and defense are worthy of a serious discussion. In this paper I put forth such a discussion. The (...) result is what we should have expected all along: PI is not only implausible, but arguably false. (shrink)

In a long-term transformation, that begins in Antiquity but takes a crucial turn in the Renaissance anatomies, the “fibre” becomes from around 1750 the operative building block and at the same time the first unifying principle of function-structure-complexes of organic bodies. It occupies the role that the cell takes up in the cell œconomies of the second third of the nineteenth century. In this paper, I will first discuss some key notions, technical analogies, and images that are related to “fibre”-concepts (...) from Andreas Vesalius to Albrecht von Haller and then focus on Charles Bonnet's and Denis Diderot's fibre œconomies. In Bonnet's and Diderot's fibre œconomies, the self-active, regulating properties of fibre-agents and their material structures, that reach from fibre bundles, tissues and membranes to apparati of organs, are united within the concrete whole of individual organized “systems” or “networks.”.

There will be a few themes. One to get us going: expansion versus contraction. About an object, o, and the region, R, of space(time) in which o is exactly located,1 we may ask: i) must there exist expansions of o: objects in filled superregions2 of R? ii) must there exist contractions of o: objects in filled subregions of..

This paper offers an argument in favour of a Lewisian version of concretism that maintains both the principle of material inheritance (according to which, if all the parts of an object x are material, then x is material) and the materiality-modality link (that is, the principle that, for every x, if x is material, then x is possible).

A questão "se uma elocução perde seu significado com a destruição das coisas "surge como uma questão sobre o valor-verdade de declarações com um termo vazio como sujeito, a saber, como um subproblema do sofisma "Se 'omnis homo de necessitate est animal' é verdade quando não há homem algum ". Neste trabalho, trarei as discussões conforme elas se apresentam em "De signis" IV.2 de Roger Bacon, em "Quaestiones logicales", q. 2–3 de Peter John Olivi, no OHNEA de Boethius of Dacia, (...) e no OHNEA de Anonymus Alani. Tais textos nos apresentam quatro modos diversos de nos relacionarmos com a questão sobre significação para OHNEA e, assim, com quatro posições diferentes sobre a relação entre significação e referência vazia. Usarei Anonymus Alani como o fio conductor de minha análise, inserindo outras posições onde tal se fizer relevante.The question 'whether an utterance loses its signification with the destruction of things ' is raised as a question about the truth-value of assertions with an empty term as a subject, namely as a sub-problem of the sophism 'Whether "omnis homo de necessitate est animal" is true when no man exists '. In this paper, I shall introduce the discussions as they are present in Roger Bacon's "De signis" IV.2, Peter John Olivi's "Quaestiones logicales", q. 2–3, Boethius of Dacia's OHNEA, and Anonymus Alani's OHNEA. These texts present us with four different ways of relating the question about signification to OHNEA, and therefore with four different positions regarding the relation between signification and empty reference. I shall use Anonymus Alani as the guiding thread of my analysis, inserting other positions where it is relevant. (shrink)

It is plausible that the universe exists: a thing such that absolutely everything is a part of it. It is also plausible that singular, structured propositions exist: propositions that literally have individuals as parts. Furthermore, it is plausible that for each thing, there is a singular, structured proposition that has it as a part. Finally, it is plausible that parthood is a partial ordering: reflexive, transitive, and anti-symmetric. These plausible claims cannot all be correct. We canvass some costs of (...) denying each claim and conclude that parthood is not a partial ordering. Provided that the relevant entities exist, parthood is not anti-symmetric and proper parthood is neither asymmetric nor transitive. (shrink)

Power metaphysicians are concerned with, well, powers. Theists claim interest in the most powerful entity there is, God. As such, recent work on the ontology of powers may well have much to offer theists when thinking about God’s power. In this paper I start to provide a metaphysics of God’s ‘power’, something many definitions of omnipotence make reference to. In particular I will be interested in explicating how a power ontology can account for the strength and range of God’s power, (...) as well as showing how this account of divine power can fit with a timeless conception of God.

In this paper, we provide a detailed critical review of current approaches to ecthesis in Aristotle’s Prior Analytics, with a view to motivate a new approach, which builds upon previous work by Marion & Rückert (2016) on the dictum de omni. This approach sets Aristotle’s work within the context of dialectic and uses Lorenzen’s dialogical logic, hereby reframed with use of Martin-Löf's constructive type theory as ‘immanent reasoning’. We then provide rules of syllogistic for the latter, and provide proofs (...) of e-conversion, Darapti and Bocardo and e-subalternation, while showing how close to Aristotle’s text these proofs remain.

Peter Auriol was one of the most influential authors of the generation after Scotus. He developed an anti-realist ontology (he denied the extra-mental existence of common natures and consequently the necessity of a principle of individuation) and a new epistemology. In his view, the mental world is somehow richer than the extra-mental one, since our mind can abstract general notions (such as humanitas) that are not matched by general objects in reality. The article is aimed to show how, according to (...) Auriol, the individual things existing outside are the grounds on which all our notions (even the general and abstract ones) are based. Accordingly, the first section analyzes the internal composition of the individual things: material suppositum and singular form, which are interrelated as potency and act. The second section deals with Auriol’s theory of knowledge. In particular, it focuses on the relation between our notions, both concrete and abstract, and the metaphysical parts of extra-mental individuals. The general, abstract notions originate from the formal parts (the singular substantial form) of extra-mental individuals, while the concrete notions from the whole individuals. (shrink)

In “Extensionality of Parthood and Composition,”1 Achille Varzi mounts a spirited defense of the extensionality of parthood, or ‘EP’. According to EP, if x and y are composite objects with all the same proper parts then x = y.2 A number of philosophers, he notes, have objected that EP is false on the grounds that, for example, a statue and lump of clay (or a tinkertoy house and the wood from which it is made, in Varzi’s example) are (...) distinct yet share all their proper parts. A number of considerations — for example, that a statue and lump of clay have different persistence conditions — are commonly raised to support this non-extensionalist conclusion. Varzi maintains, on the other hand, that this case and others like it do not support non-extensionalism. However, there are reasons to doubt the cogency of his argument. In outline, Varzi’s argument runs as follows. Suppose that (i) α and β are (say) a statue and a lump, respectively,3 and also suppose that (ii) α = β. ∗This is a draft and so unsuitable for citation in any form.

I focus on three mereological principles: the Extensionality of Parthood (EP), the Uniqueness of Composition (UC), and the Extensionality of Composition (EC). These principles are not equivalent. Nonetheless, they are closely related (and often equated) as they all reflect the basic nominalistic dictum, No difference without a difference maker. And each one of them—individually or collectively—has been challenged on philosophical grounds. In the first part I argue that such challenges do not quite threaten EP insofar as they are either (...) self-defeating or unsupported. In the second part I argue that they hardly undermine the tenability of EC and UC as well. (shrink)

Defenders of the subset view of realization have claimed that we can resolve well-known worries about mental-physical causal overdetermination by holding that mental properties are subset realized by physical properties, that instances of subset realized properties are parts of physical realizers, and that part-whole overdetermination is unproblematic. I challenge the claim that the overdetermination generated by the subset view can be legitimated by appealing to more mundane part-whole overdetermination. I conclude that the subset view does not provide a unique solution (...) to overdetermination worries. (shrink)

Metaphysicians of various stripes claim that a single object can have more than one exact location in space or time – e.g. endurantists claim that an object persists by being ‘all there’ at different moments in time. Antony Eagle has developed a formal theory of location which is prima facie consistent with multi-location, but Damiano Costa and Claudio Calosi argue that the theory is unattractive to multi-location theorists on other grounds. I examine their charge that Eagle’s theory won’t allow an (...) endurantist to account for certain cases of mereological change. I argue that the charge sticks, but not for the reasons Costa and Calosi think. Along the way, I explore an issue which is underexplored in their paper, namely, how an endurantist might modify Eagle’s theory to incorporate a parthood relation which obtains, not absolutely, but only relative to times.

Despite having faced severe criticism in the past, mereological approaches to group ontology, which argue that groups are wholes and that groups members are parts, have recently managed a comeback. Authors such as Katherine Ritchie and Paul Sheehy have applied neo-Aristotelian mereology to groups, and Katherine Hawley has defended mereological approaches against the standard objections in the literature. The present paper develops the mereological approaches to group ontology further and proposes an analysis of group membership as parthood plus further (...) restrictions. While all mereological accounts agree that group members are parts of the group, it has become clear that this analysis is insufficient. I discuss three proposals to develop the mereological analysis of group membership and then put forward a combined solution to the puzzle. According to my proposal, the members of a reading group are agents who are part of the group and have been designated to contribute to the group. (shrink)

What is a temporal part? Most accounts explain it in terms of timeless parthood: a thing's having a part without temporal qualification. Some find this hard to understand, and thus find the view that persisting things have temporal parts--fourdimensionalism--unintelligible. T. Sider offers to help by defining temporal parthood in terms of a thing's having a part at a time. I argue that no such account can capture the notion of a temporal part that figures in orthodox four-dimensionalism: temporal (...) parts must be timeless parts. This enables us to state four-dimensionalism more clearly. (shrink)

This article presents a semantic analysis of indirect speech reports. The analysis aims to explain a combination of two phenomena. First, there are true utterances of sentences of the form α said that φ which are used to report an utterance u of a sentence wherein φ's content is not u's content. This implies that in uttering a single sentence, one can say several things. Second, when the complements of these reports (and indeed, these reports themselves) are placed in conjunctions, (...) the conjunctions are typically infelicitous. I argue that this combination of phenomena can be explained if speech reports report (perhaps contingent) parts of the contents of the sentences reported. (shrink)

In this study, I present the Chan Buddhist alternative to phronesis or ‘practical wisdom’. Instead of involving the skill or ‘know-how’ in applying moral principles to particular situations, the Chan Buddhist virtuously responds to situations because they understand how each situation is a ‘part’ of a larger whole or a ‘function’ (用) of the ‘body’ (體). Ultimately, this sensitivity to how each situation is meaningfully situated within a context of relationships is what motivates the Chan Buddhist’s spontaneous compassion towards the (...) suffering of existence in its entirety.
