This article is aimed at highlighting some possible contributions of Hegel’s philosophy to the contemporary debate around process metaphysics. In the contemporary metaphysical debate, process metaphysics represent an attempt to highlight the limits of the traditional philosophical paradigm, which is based on the notion of substance, and to work within an alternative paradigm, which is based on the notion of process. What exists, then, are not substances, substrates, fixed and stable objects characterized by certain properties, but (...) processes, events, occurrences. The main idea of ​​process metaphysics is that being is dynamic and that this dynamic nature must be the main focus of any comprehensive philosophical explanation of reality. Looking at this revolution, it is necessary to define the very notion of process. In fact, this work of conceptual clarification of the fundamental notion of this new philosophical paradigm is still ongoing. My idea is that Hegelian philosophy can offer some relevant indications to do the job. In this sense, the article will be divided into two parts: on the basis of the analysis of some definitions of the notion of process in the contemporary debate around process metaphysics, I will show 1) the need to determine the minimal ontological structure of the notion of process; 2) the possibility of determining this structure through some conceptual tools provided by Hegel’s logic and in the Lectures on the History of Philosophy.

IN DEBATES CONCERNING the relationship between basic principles of Whiteheadian process philosophy and the classical doctrine of substance, one can distinguish at least three types of essentially different approaches to the discussed issue: Process metaphysics implies definitive rejection of substantialist categories of traditional philosophy, and introduces a radically new perspective in which notions of flux and change replace the former categories of enduring substances and relative immutability of individual subjects. Whitehead's approach to the traditional doctrine of substance results (...) in a strong critique of it but not in total rejection. Certain elements of the Aristotelian and Cartesian legacy must be critically revised, but they cannot be eliminated from a rational interpretation of nature. Their implicit presence in Whiteheadian interpretative schemes substantiates the opinion that process metaphysics introduces a reformed version of the doctrine of substance. In spite of explicit critique of the concept of substance found in Whitehead's texts, the same texts implicitly presuppose the necessity of reference to certain substantialist categories. Whitehead himself did not always formally recognize such a necessity; his metaphysical assertions, however, provide an objective basis for developing a modified theory of substance. (shrink)

Michael Wedin argues against the prevailing notion that Aristotle's views on the nature of reality are fundamentally inconsistent. According to Wedin's new interpretation, the difference between the early theory of the Categories and the later theory of the Metaphysics reflects the fact that Aristotle is engaged in quite different projects in the two works--the earlier focusing on ontology, and the later on explanation.

At the opening of Spinoza’s Ethics, we find the three celebrated definitions of substance, attribute, and God: E1d3: By substance I understand what is in itself and is conceived through itself, i.e., that whose concept does not require the concept of another thing, from which it must be formed [Per substantiam intelligo id quod in se est et per se concipitur; hoc est id cujus conceptus non indiget conceptu alterius rei, a quo formari debeat]. E1d4: By attribute I (...) understand what the intellect perceives of a substance, as constituting its essence [Per attributum intelligo id, quod intellectus de substantia percipit, tanquam ejusdem essentiam constituens]. E1d6: By God I understand a being absolutely infinite, that is, a substance consisting of an infinity of attributes, of which each one expresses an eternal and infinite essence We are accustomed to think of these paramount definitions as a fixed and settled formulation of the core of Spinoza’s metaphysics, but if we look at the development of Spinoza’s thought, the picture we get is quite different. In the early drafts of the Ethics and in his early works, Spinoza seems to have experimented with various conceptualizations of the relations between substance, attribute, and God. Some of Spinoza’s works make barely any use of the notions of substance and attribute, and the testimony of Spinoza’s letters suggests that, at a certain stage in his philosophical development, the concept of attribute may have been put on the back burner, if not completely dropped. Indeed, another closely related concept—accident [accidens]—was fated to be pulled out of the system (and for good reasons ). The final version of the Ethics makes hardly any use of this notion, but Spinoza’s letters show that in early drafts of the Ethics he used the term ‘accident’ to refer to what cannot be or be conceived without substance. In this paper I will attempt to provide a brief outline of the genealogy of Spinoza’s key metaphysical concepts. This genealogy, like any other, can help us to reexamine and reconsider what seems to us natural, stable and obvious. In the first part of the paper, I rely on Spinoza’s letters to trace the development of his definitions of substance and attribute in the early drafts of the Ethics. The letters, whose dates are more or less established, also provide a temporal grid for our subsequent discussions. The second part surveys Spinoza’s discussion and conceptualization of substance and attributes in the Treatise on the Emendation of the Intellect, the Theological-Political Treatise (1670), and briefly, Spinoza’s 1663 book on Descartes’ Principles of Philosophy, and its appendix on Metaphysical Thoughts, the Cogitata Metaphysica. The third part of the paper is dedicated to Spinoza’s understanding of substance and attribute in the Short Treatise on God, Man, and His Well-Being. I conclude with some remarks on the stability of Spinoza’s final position on the issue, as expressed in the published version of the Ethics . (shrink)

‘Substance’ (substantia, zelfstandigheid) is a key term of Spinoza’s philosophy. Like almost all of Spinoza’s philosophical vocabulary, Spinoza did not invent this term, which has a long history that can be traced back at least to Aristotle. Yet, Spinoza radicalized the traditional notion of substance and made a very powerful use of it by demonstrating – or at least attempting to demonstrate -- that there is only one, unique substance -- God (or Nature) -- and that (...) all other things are merely modes or states of God. Some of Spinoza’s readers understood these claims as committing him to the view that only God truly exists, and while this interpretation is not groundless, we will later see that this enticing and bold reading of Spinoza as an ‘acosmist’ comes at the expense of another audacious claim Spinoza advances, i.e., that God/Nature is absolutely and actually infinite. But before we reach this last conclusion, we have a long way to go. So, let me first provide an overview of our plan. In the first section of this paper we will examine Spinoza’s definitions of ‘substance’ and ‘God’ at the opening of his magnum opus, the Ethics. Following a preliminary clarification of these two terms and their relations to the other key terms defined at the beginning of the Ethics, we will briefly address the Aristotelian and Cartesian background of Spinoza’s discussion of substance. In the second section, we will study the properties of the fundamental binary relations pertaining to Spinoza’s substance: inherence, conception, and causation. The third section will be dedicated to a clarification of Spinoza’s claim that God, the unique substance, is absolutely infinite. This essential feature of Spinoza’s substance has been largely neglected in recent Anglo-American scholarship, a neglect which has brought about an unfortunate tendency to domesticate Spinoza’s metaphysics to more contemporary views. The fourth section will study the nature of Spinoza’s monism. It will discuss and criticize the interesting yet controversial views of the eminent Spinoza scholar, Martial Gueroult, about the plurality of substances in the beginning of the Ethics; address Spinoza’s claim in Letter 50 that, strictly speaking, it is improper to describe God as “one”; and, finally, evaluate Spinoza’s kind of monism against the distinction between existence and priority monism recently introduced into the contemporary philosophical literature. The fifth and final section will explain the nature, reality, and manner of existence of modes. We therefore have an ambitious plan; let’s get down to business. (shrink)

It is argued that a concept of substance is possible which not only avoids metaphysical blind alleys but is worthy of serious philosophical attention. Starting with parker's notion of substance a conception is developed in which substance has the moments of haecceity, Logical independence, Causal independence, Causal efficacy, And conservation through change. Event and substance ontologies are compared and reasons for the superiority of the latter given. The results are related to the problem of (...) personal identity, And it is suggested that a person's body may be identifiable by him by means of his person rather than the converse. (shrink)

In this paper I discuss the role played by Ernst Mach on Nietzsche’s thought. Starting from the contents of his Beiträge zur Analyse der Empfindungen, I’ll show the close similarities between their view on both human knowledge and the scientific world description. In his writing on science Nietzsche shares Mach’s critique to the 19th century mechanism and its metaphysical ground, as much as his way of defining the substantial notions such as matter, ego and free will. Moreover, my investigation (...) will make it clear that Mach cannot be seen as a direct source of Nietzsche’s thought, since the latter wrote many times on the same subjects long before his first reading one of his works. Rather, it is possible to consider the writings of Lange, Spir and Spencer as the first sources of Nietzsche’s views on the main themes Mach dealt with in his work from 1886. (shrink)

Modern commentators recognize the irony of Aristotle’s Categories becoming a central text for Platonic schools. For similar reasons, these commentators would perhaps be surprised to see Aquinas’s In VII Metaphysics, where he apparently identifies the secondary substance of Aristotle’s Categories with a false Platonic sense of “substance” as if, for Aristotle, only Platonists would say secondary substances are substances. This passage in Aquinas’s commentary has led Mgr. Wippel to claim that, for Aquinas, secondary substance and essence are (...) not the same thing and that Aristotle’s notion of essence is absent from the Categories. This paper—by closely analyzing the apparently contradictory divisions of “substance” in Aquinas’s In V and VII Metaphysics—shows that essence and secondary substance are not altogether distinct for Aquinas. Moreover, when the Categories is viewed by Aquinas as a work of logic, it is found largely to cut across the disputes between Platonism and Aristotelianism. (shrink)

In his “Farewell to Substance: A Differentiated Leave-Taking”, Peter Simons reaches the provocative conclusion that the concept of substance, as it is employed by metaphysicians, has become obsolete, since in the end there may be nothing at all which answers to it. No harm is done, Simons allows, if we continue to retain an everyday notion of substance, as long as we are aware of the limitations of this practice: there is no reason in general to (...) expect that what is salient from our specifically human point of view will retain a special place in light of our most considered scientific and metaphysical theories of the world. In this paper, I argue that, contrary to Simons’ pessimistic outlook, the concept of substance continues to retain its importance for metaphysics. Among the primary explanatory roles played by the concept of substance in metaphysics is its use in designating certain kinds of entities as occupying a privileged position relative to a particular ontology. But disputes over substancehood can also target the criteria themselves relative to which an ontologically privileged position is awarded to certain taxonomic categories. In these uses, we see the concept of substance employed in an absolute, a relational and a comparative sense, to designate items as substances simpliciter, as the substances of something else, or as more or less deserving of substance status.

Aristotle’s notion of substance and its relation to his investigation of the question of being qua being in the Metaphysics is one of the most important, enduring, and intriguing problems in scholarship focused on Aristotle and the tradition of metaphysics. This article explores some of the more recent developments in this area of scholarship, especially the trend toward more dynamic interpretations of Aristotle’s conception of substance, as a way of renewing the question of what Aristotle really means (...) by being. On this basis, the article reinterprets Aristotle’s investigation of substance as the primary sense of being in the Metaphysics. It argues that there are two primary ways substance may be considered; with respect to the principles of intelligibility of substance and with regard to the causal framework of the real unity and determinacy of substance. The primary principles of the intelligibility of substance, it is argued, are end and fulfilment (telos and entelechy). The causal framework of the real unity and determinacy of substances, on the other hand, can be understood via the notion of act and activity (energeia). (shrink)

In Chapter One I present an interpretation of Descartes' theory of distinction. I argue that the best understanding of the notion of separate existence at stake in the real distinction between mind and body is not that each can exist without the other existing, nor that each can exist without a real union with the other, but that each can exist without the attributes of the other. However, the only notion of separate existence which can provide an adequate (...) acccount of all three kinds of distinction--real, modal, and of reason--is that of one thing existing without a real union with another thing. ;In Chapter Two I examine Descartes' claims about the dependence of created substances on God and their independence from other creatures. The pure substances, those which are not composed of parts, can be caused to come into existence and go out of existence only by God, and they can perish only by annihilation. These substances include individual created minds and the extended universe considered as a whole. In contrast, bodies and human beings, which are composed of parts, can be caused to go out of existence by other creatures, and they can perish without being annihilated. Nevertheless, I argue that Descartes thinks bodies and human beings are full-fledged substances. ;In Chapter Three I discuss the union of mind and body. I argue that Descartes thinks the human soul is the only substantial form and that it inheres in the body as form inheres in matter. I defend his account of how two substances can form a unity by comparing it with medieval accounts of the unity of composites. ;Chapter Four examines Descartes' arguments for rejecting substantial forms and the so-called real qualities. I argue that his earliest series of arguments, those from perception and scientific explanation, is the most successful. ;Finally, in Chapter Five, I consider Descartes' positive account of the status of those so-called real qualities which he asserts are merely sensations, for example, color, sound, and heat. I argue that he is best understood as holding that they are modes of both thought and extension which are property ascribed to the composite of mind and body. (shrink)

Despite the notions of possible worlds and substances are very important subjects of contemporary metaphysics, there are relatively few attempts to combine these in a united framework. This paper considers the metaphysical model of the origins and the evolution of possible worlds that occurs from an interaction between substances. I involve Leibniz’s doctrine of the striving possibles that every possibility of substance has its own essence and tendency towards existence. It is supposed that the activities of substances are (...) constantly aimed at using this tendency in all possible ways. Only the consistent and stable interactions between the substances give birth to stable objects in one of many worlds. Thus activity of substances changes from the possible modality of being to the actual modality of being in form of existence of the worlds. I divide substance’s possibility into two aspects—dynamic (possible or virtual history) and static (possible or potential mutual state). Thanks to the summation of virtual histories, in the possible modality of being, the maximal number of virtual histories is combined into the actual history in the actual modality. (shrink)

Locke’s theory of personal identity was philosophically groundbreaking for its attempt to establish a non-substantial identity condition. Locke states, “For the same consciousness being preserv’d, whether in the same or different Substances, the personal Identity is preserv’d” (II.xxvii.13). Many have interpreted Locke to think that consciousness identifies a self both synchronically and diachronically by attributing thoughts and actions to a self. Thus, many have attributed to Locke either a memory theory or an appropriation theory of personal identity. But the former (...) stumble on circularity and the latter is insufficient for Locke’s moral theory insofar as he is committed to a theory of divine rectification. The common problem is that Locke’s theory seems to demand an objective, or metaphysical, fact of a continuing consciousness that does not appeal to a traditional notion of substance for the continuity. I’m suggesting something new. In II.xxvii of the Essay, we see an ambiguity in Locke’s use of the term ‘consciousness’. Locke seems to see consciousness as both a mental state by means of which we are aware of ourselves as perceiving and as the ongoing self we are aware of in these conscious states. First, I make the textual argument why we should read Locke as having a conception of a metaphysical fact of a continuing consciousness that does not appeal to thinking or bodily substance to establish its continuity. I then argue that the metaphysical fact of an enduring consciousness is revealed to us as a phenomenological fact of experience. Due to the nature of certain kinds of perceptual situations we have an experience of ourselves as temporally extended. Although the text bears out that Locke seemed to think there is a fact of an ongoing consciousness, I argue that it is consistent with his reluctance elsewhere that he makes no further epistemological or ontological claims about it. Finally, I provide an account of Locke’s understanding of memory and its relation to consciousness that supports the claim that consciousness is something ontologically distinct from either thinking or bodily substance.

Substance ontologists claim that substances are ontologically primary because the category of substance enjoys unique explanatory potential. Unless it can be shown that "only" substances fulfill the central explanatory tasks in ontology, this inference from explanatory success to ontological primacy amounts to a fallacy akin to the error Whitehead called 'the fallacy of misplaced concreteness'. I investigate recent prototypical arguments for substance metaphysics and try to show that some explanatory functions of substance can also be fulfilled (...) by other ontological categories. In particular, I argue against M. Ayers that there is no reason to think that all and only substances are discrete individuals, natural wholes, and logical units. I conclude that the category of substance does not provide us with a uniquely powerful explanans for the notion of logical and physical unity. (shrink)

Resumen En este trabajo evaluamos el impacto que la adopción de la relatividad del movimiento tiene en la metafísica de Leibniz. En particular argumentamos que el abandono de la comprensión absolutista del mismo anula su noción juvenil de sustancia corpórea. En primer lugar analizamos cómo entiende Leibniz las nociones de cuerpo y movimiento en el periodo juvenil y defendemos que la comprensión absolutista de este último constituye una piedra angular en su primera concepción de la sustancia corpórea. En segundo lugar (...) exponemos los argumentos leibnizianos a favor de la relatividad del movimiento durante el período parisino y mostramos su repercusión en el concepto juvenil de sustancia corpórea.In this paper we evaluate the impact of Leibniz's defense of relativity of motion on his metaphysics. We argue that the abandonment of the absolutist position makes void his first notion of corporeal substance. First, we analyze Leibniz's conception of body and movement in his youth and explain how the assumption of absolute motion during these years plays a role in his notion of corporeal substance. Second, we examine his arguments in favor of relativity of motion during the Parisian period and show the repercussion on his first conception of the corporeal substance. (shrink)

In recent years we have seen the rise of a new framework within the study of the mind, namely Predictive Processing. This framework essentially holds that the brain is a prediction machine constantly postulating perceptual models which are tested against incoming information. At the same time, the notion of the minimal or core self has become very influential as a way of explaining, or explaining away, pre-reflective self-awareness. The four most widely discussed alternatives for thinking through the metaphysical (...) implications the pre-reflective sense of self are the standard phenomenological view, the substance view, the no-self view and by now the relational view. In this paper, it is our objective to rethink the notion of the sense of self in the context of PP. Now, PP is often held to be a unifying framework that offers a new integrated account of perception, cognition, imagination, and indeed the pre-reflective sense of self. We will show, however, that PP has been taken to endorse rather too many different metaphysical accounts of self: that is, views about how we should regard the ultimate nature of self. What we need to do, if possible, is to use PP to constrain the theories on offer. Here we focus upon two central constraints that we think PP implies. These are, the mutability constraint and the multi-layereredness constraint. We argue that self-views laid out in terms of the PP framework are usually – to some degree – located within the four standard metaphysical accounts of self. However, we think that realist versions of self-accounts seem to have more trouble in respecting the PP constraints or requirements. The reason, or so we believe, is PP’s mutability constraint. This does not have to be the case and we, therefore, propose an alternative realist view – namely the pre-reflective situational self view – which is more adequate to fit the PP framework. (shrink)

In the Discourse on Metaphysics Leibniz put forward his famous complete-concept definition of substance. Sometimes this definition is glossed as stating that a substance is an entity with a concept so complete that it contains all its predicates, and it is thought that it follows directly from Leibniz’s theory of truth. Now, an adequate definition of substance should not apply to accidents. But, as I shall point out, if Leibniz’s theory of truth is correct then an accident (...) is an entity with a concept so complete that it contains all its predicates. The aim of this paper is to clarify Leibniz’s notion of substance in the Discourse with a view to explaining how that definition successfully distinguishes between substances and accidents. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:On Substance Being the Same As Its Essence in Metaphysics Z 6: The Pale Man ArgumentNorman O. Dahlin general Aristotle’s account of substance in the Categories is clear. Primary substances, the basic constitutents of the world, are independently existing individuals, paradigm examples of which are particular living organisms. However, the later use to which Aristotle puts matter and form provides him with two new candidates for primary (...) substance.1 A reconsideration of substance is in order, and Aristotle begins it in Metaphysics Z. The status of matter soon becomes clear. It can’t be substance because it isn’t a “this” and separate (Z 3, 1029a26–28). The status of form, however, is another story. Aristotle argues in Z 6 that substances are the same as their essences. While the evidence isn’t unequivocal, Z 4, 10, 11, and 15 take essence to be form, where form is universal. Z 13, however, argues that no universal is substance. Aristotle thus appears caught in an inconsistency. Substance is universal form because it is the same as universal form; however, no universal is substance. This and other problems have led to as wide a variety of interpretations of Metaphysics Z as one will find of any philosophical text. Virtually all of them end up attributing to Aristotle one of [End Page 1] three views about substance—substances are universal forms, particular forms, or composites of matter and form.2This paper takes a first step in a project that promises to remove the above inconsistency while allowing but not requiring Aristotle to take concrete particular substances (composite substances involving both matter and form) to be substances. The project looks at the first of the three claims that lead to the above apparent inconsistency and asks whether the sameness relation in it should be understood as identity or a weaker relation that could hold between concrete particular substances and their universal essences. It is the latter possibility that promises to avoid the above contradiction. If concrete particular substances can be the same as their universal essences, then the essences of substances can be universals without necessarily turning substances into universals. Nevertheless, granting this possibility wouldn’t require Aristotle to take concrete particular substances to be substances. Forms of concrete particular substances will also be the same as their essences in this weaker sameness relation, and considerations other than those at work in Z 6 could still lead Aristotle to rule out concrete individuals as substances.1Although Aristotle has standardly been interpreted as arguing in Z 6 that substances are identical with their essences,3 two considerations allow the question of this paper to be raised. [End Page 2]The first is the variety of uses to which Aristotle puts such notions as the same (tauto) or one (hen). Aristotle’s concern in Z 6 is with whether certain things are or are not the same (tauto), one (hen), or one and the same (hen kai auto and to auto kai hen) as their essences.4 He argues that kata sumbebēkos legomena (things said to be what they are with respect to an accident) are not the same as their essences, but that kath’ hauta legomena (things said to be what they are with respect to themselves), a class of things that includes substances,5 are the same as their essences. However, when Aristotle says that one thing and another are the same or one, there is more than one kind of claim he can be making. Some of them apply to things that are identical; others do not.For example, things can be the same in number, species, and genus. A doublet and a cloak are the same in number, a man and another man are the same in species, and a man and a horse are the same in genus.6 Although a doublet and a cloak are identical, a man and another man, and a man and a horse, are not.Things can also be accidentally the same, or the same in definition, substance, or essence,7 where these two ways of being the same cut across the previous ways of being the same. For example... (shrink)

This book explores the metaphysics of political communities. It discusses how and why a plurality of individuals becomes a political unity, what principles or forces keep that unity together, and what threats that unity can be faced with. In Part I, the author justifies the need for the notion of substance in metaphysics in general and in the metaphysics of politics in particular. He spells out a moderately realist theory of substances and of their principles of unity, which (...) supports substantial gradualism. Part II concerns action theory and the nature of practical reason. The author claims that the acknowledgement of reasons by agents is constitutive of action and that normativity depends on the role of the good in the formation of reasons. Finally, in Part III the author addresses the notion of political community. He claims that the principle of unity of a political community is its authority to give members of the community moral reasons for action. This suggests a middle way between liberal individualism and organicism, and the author demonstrates the significance of this view by discussing current political issues such as the role of religion in the public sphere and the political significance of cultural identity. Authority and the Metaphysics of Political Communities will be of interest to researchers and advanced students working in social metaphysics, political philosophy, philosophy of action, and philosophy of the social sciences.

In his thoughtful and generous review of my book, Leibniz’s Metaphysics: Its Origins and Development, Cees Leijenhorst accepts many of its most radical conclusions: that Leibniz’s metaphysics evolved out of an attempt to combine ideas gathered from the great philosophers of the past and to do so in a manner that would solve the theological, legal, and philosophical questions that most concerned him; that although Leibniz’s notion of substance developed out of his interpretation of the philosophy of Aristotle, (...) his conception of the relation between God and creatures has its roots in the Platonism that he learned as a young man in Leipzig and Jena; that the views constituting the core doctrines of the mature philosophy were conceived by the time Leibniz went to Paris in early 1672; and that Leibniz rejects the reality of passive extended matter and embraces his own version of idealism as early as 1671. I am tempted to respond with a loud rodeo yell and end it at that. But because the few points on which. (shrink)

We argue in this paper that Leibniz’s characterization of a substance as “un être” in his correspondence with Arnauld stresses the per se unity of substance rather than oneness in number. We employ two central lines of reasoning. The first is a response to Mogens Lærke’s claim that one can mark the difference between Spinoza and Leibniz by observing that, while Spinoza’s notion of substance is essentially non-numerical, Leibniz’s view of substance is numerical. We argue (...) that Leibniz, like Spinoza, qualifies the substance as “one” primarily in a non-numerical sense, where non-numerical means per se unity or qualitative uniqueness. The second line of reasoning suggests that the term “one” should be understood as a-unity-presupposed-by-multiplicity in two senses: a) externally, in the sense of being presupposed by higher complex structures, such as aggregates, and, b) internally, in the sense of having itself a complex structure. We develop an analogy along these lines between the role the notion of a fundamental unity plays in Leibniz’s view of numbers and his view of substance. In other words, we suggest that looking at the role units play in Leibniz’s view of mathematics can shed some light on the role they play in his metaphysics. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Metaphysics of Creation. Aquinas's Natural Theology in Summa contra gentiles IIE.J. AshworthNorman Kretzmann. The Metaphysics of Creation. Aquinas's Natural Theology in Summa contra gentiles II. Oxford: Clarendon Press, 1999. Pp. xiii + 483. Cloth, $65.00.Thomas Aquinas is astounding not just for the richness, complexity and timeless interest of his thought, but for the sheer bulk of his works. The challenge this bulk presents to commentators has been (...) taken up in various ways. Some people focus on Aquinas's architectonic, giving a global overview of individual works in such terms as the neo-Platonic exitus-reditus schema; others focus on the interplay of faith and reason in his works by classifying Aquinas as a theologian, or a Christian philosopher, or a philosopher-theologian; still others try to organize his thought by bringing together thematically-linked discussions from a variety of places. All three approaches tend to overlook perhaps the most striking feature of Aquinas's writings: the continuous progression of carefully-formulated, detailed arguments and sub-arguments.In the second book of his uncompleted trilogy on Summa contra gentiles, Norman Kretzmann combines the best of the first two approaches to Aquinas with an impressive and largely successful attempt to come to terms with Aquinas as an arguer. He takes an ample selection of Aquinas's own arguments in their order of appearance in SCG II; he analyzes their premisses; he shows how they function in relation to earlier and later arguments; and he criticizes their weaknesses. He does all this in an elegant, lucid prose that ensures the attentive reader an enhanced understanding of the specific topics discussed by Aquinas. [End Page 434]To understand the full import of the arguments examined, however, we need to consider what Aquinas hopes to achieve by his sequences of arguments. While granting that Aquinas is a theologian, and that he intends his Summa contra gentiles to give a full account of what Christians believe, Kretzmann argues that the first three books of SCG present a fully-developed natural theology which can serve as guide and inspiration to thinkers today. The key to understanding Aquinas here is the recognition that the philosopher, particularly the metaphysician, is, or should be, concerned with the first principles and most ultimate aspects of reality. If it turns out, as most philosophers before the twentieth century have believed, that these first principles are divine, then truths taught by revelation can be integrated with truths arrived at by reason. Moreover, once the existence and nature of God have been established, or at least rendered plausible, one can take God as a starting point for the explanation of this-worldly phenomena, from the nature of the physical world to the nature of the human person. This explanation, while buttressed by references to Biblical revelation, will nonetheless be fully natural, insofar as it relies on arguments whose premisses are those available to any rational being independently of revelation.In his earlier book, The Metaphysics of Theism (Oxford, 1997) Kretzmann examined the start of Aquinas's natural theology, the movement from things around us to God. In The Metaphysics of Creation, finished just before his death, Kretzmann takes up the emergence of things from God. The book is divided into three unequal parts. First, there is a long discussion of Aquinas's view of creation, and the precise way in which the world is dependent upon God, its first cause. Particularly notable in this section is the discussion of Aquinas's view that creation is compatible with the notion of a beginningless world. The second, very brief, section takes up Aquinas's treatment of the emergence of different species, and his willingness to reject the kind of literal reading of Genesis espoused by contemporary creationists. The third and longest section takes up the nature of the human mind or soul. What makes this section particularly interesting is its emphasis on the implications of the top-down approach. If we start with the ideas that God is a pure intellect, and that immaterial substance is possible, then the mind-body problem becomes that of explaining how intellect can ever be closely related to matter, rather that...

This paper analyzes the theory of mixtures, material substances and corpuscles put forward by the Portuguese Thomistic philosopher Francisco Soares Lusitano. It has been argued that the incapacity of the Aristotelian-Thomistic tradition to reconcile an Aristotelian theory of mixtures with hylomorphism opened the way to the triumph of atomism in the seventeenth century. By analyzing Soares Lusitano’s theory of mixtures, this paper aims to demonstrate that early modern Thomism not only rendered the Aristotelian notion of elements compatible with the (...) metaphysical bases of hylomorphism, but further incorporated an explanation of physical phenomena based upon the notion that bodies were basically made up of small and subtle corpuscles. By doing so, it shows that, contrary to what is so often claimed, early modern corpuscularism was not intrinsically incompatible with late Aristotelian philosophy. (shrink)

Leibniz used Descartes’ strict notion of substance in “That a Most Perfect being is Possible” to characterize God but did not intend to undermine his own philosophical views by denying that there are created substances. The metaphysical view of substance in this passage is Cartesian. A discussion of radical substance without any sort of denial in the possibility of other substances does not indicate Spinozism. If this interpretation is correct, then the passage is neither anomalous (...) nor mysterious. There is reason to believe that the passage expresses just the beliefs that we should expect Leibniz to hold in his De Summa Rerum period. Furthermore, this interpretation indicates that while Leibniz’s metaphysics during this stage of his career is suggestively similar to Spinoza’s, there is no evidence that Leibniz accepted Spinoza’s pantheistic conclusion.

Argues that Leibniz's denial of counterfactual or transworld identity is grounded in metaphysical considerations – specifically in his belief in a coalescence of conceptual connections and causal connections, which is marked by his revival and adaptation of the Scholastic Aristotelian notion of substantial form. Exploration of Leibniz's views about miracles and about perceptual relations leads to the conclusion that his denial of counterfactual identity does not claim intrinsic metaphysical necessity, but appeals to considerations of God's wisdom and (...) goodness; and that he can deny transworld identity only on the assumption that only aggregates of mutually harmonious substances count as worlds.

The *Tractatus* contains an argument that there are simple, necessarily existent objects, which, being simple, are suited to be the referents of the names occuring in the final analysis of propositions. The argument is perplexing in its own right, but also for its invocation of the notion of "substance". I argue that if one locates Wittgenstein's conception of substance in the Kantian tradition to which his talk of "substance" alludes, what emerges is an argument that is (...) very nearly--but not quite--cogent.

Scholars paid scant attention to Giles of Rome’s Quaestiones methaphisicales. This is due to many reasons. The Quaestiones are likely the first of the Aristotelian commentaries written by Giles and all XVI-century printed editions conserve but a reportatio of the course on Metaphysics that Giles probably gave in Paris between 1268/1269 and 1271. Since Giles never edited the text of his lectures, we cannot be sure that Giles approved the list and the contents of the questions we may read today. (...) Moreover, the current list is also incomplete because a study of cross-references in Giles’ Aristotelian commentaries showed that Giles wrote other questions, not included in the list we have today. Despite of these features, Giles’ Quaestiones are import both historically and philosophically. They contribute to fixing the chronology of Giles’ first works and to illustrating the metaphysics of the early Giles. In particular, a close examination of the questions on Books VII and VIII of Aristotle’s Metaphysics, devoted to substance and accidents, shows various things. For example, the influence exerted by Averroes’s Commentary on Giles’s teaching and, accordingly, the pivotal role played by the notion of definition in the explanation of the essence of substance and accidents. More generally, such an examination permits us bringing to light the exegetical devices Giles used in order to reconcile Thomas Aquinas’s view of the primacy and unicity of substantial form with his idiomatic position that indeterminate dimensions must precede in some way substantial form. If this were not the case, Giles argues, we could not explain the process of particularization and multiplication of a form that is in itself ‘unparticular’. (shrink)

A rejection of the notion of substance, an emphasis on intraworldly experience and an incorporation of ideas from modern biology are just three of the distinctive features of Alfred North Whitehead’s process metaphysics or philosophy of organism. The last two features give his scheme a heavily naturalistic tinge, despite his positing of eternal objects or universal forms of definiteness, which - together with subjective aims or final causes - are instantiated in a divinity prior to worldly realization.1 Such (...) a naturalism might seem to preclude largely a comparison with the work of Jacques Derrida, with other differences between the two being left aside. Derrida began his career as a student of phenomenology and structuralism, and by far the greater number of his philosophical writings has been devoted to thinkers who are explicitly post-Kantian. Yet this does not mean that he is a transcendental philosopher who abandons experience and the empirical world in favour of language and consciousness. In this paper I argue that Derrida’s work - which has been shown to be heavily informed by systems theory and evolutionary biology - is not in fact shut off from the extra-conscious and extra-linguistic dimensions of actuality. I also suggest that his deconstructive approach is strikingly similar to Whitehead’s in rejecting essentialism, namely, the idea of fixed and determined essences that underlie accidental properties and changes. From a Derridean perspective, one might even see Whitehead’s alternative as insufficiently radical, since it seems to posit not just eternal objects and God, but a cosmology in which the most fundamental beings or “actual entities” undergo no essential changes or mutations in their respective histories. It is arguable, however, that the latter conclusion would only be consequent on a restrictive interpretation of the pathways of process possible in Whitehead’s metaphysics.. (shrink)

This essay aims to analyze the structure of Aristotle's Metaphysics Θ by explicating various senses of the term δύναµις at issue in the treatise. It is argued that Aristotle's central innovation, the sense of δύναµις most useful to his project in the treatise, is the kind of capacity characteristic of the pre-existent matter for substance. It is neither potentiality as a mode of being, as recent studies maintain, nor capacity for `complete' activity. It is argued further that, in starting (...) with the κύριος sense of δύναµις as capacity for change, Aristotle begins with the most familiar and acknowledged kind of capacity, in order to move to the less familiar but ultimately more useful notion of capacity for substance, and to bring these two kinds together through an analogical relation.

Locke and Leibniz on Substance gathers together papers by an international group of academic experts, examining the metaphysical concept of substance in the writings of these two towering philosophers of the early modern period. Each of these newly-commissioned essays considers important interpretative issues concerning the role that the notion of substance plays in the work of Locke and Leibniz, and its intersection with other key issues, such as personal identity. Contributors also consider the relationship between (...) the two philosophers and contemporaries such as Descartes and Hume. (shrink)

For most of the history of metaphysics, the subject has been dominated by the concept of substance. There is an everyday commonsense notion of substance which is perfectly harmless and which I shall defend against attempts to remove it or revise it away. But I deny that substance has to be construed as a primitive even in everyday terms. Borrowing Strawson’s distinction between descriptive and revisionary metaphysics, I press the legitimate claims of revisionary metaphysics and argue (...) that there is no place for a fundamental concept of substance within it, although aspects of the concept are likely to find their place therein.

Perhaps more than any other aspect of his thought, Alfred North Whitehead’s rejection of the notion of “independent existence” or substance has been taken to define his philosophy of organism. Moreover, it is this rejection of substances which has been the source of some of the most significant objections to Whitehead’s thought. Many commentators often indicate sympathy with Whitehead’s project but ask, if the world is composed exclusively of microscopic events which neither endure nor have histories, then how (...) can Whitehead account for enduring, macroscopic individuals such as ourselves? That is, having rejected the notion of unchanging subjects of change, how can Whitehead’s account adequately capture the unity and self-identity of macroscopic individuals? The contemporary Neo-Thomist W. Norris Clarke gives voice to this potentially damaging objection. A close analysis of aspects of Clarke’s work will prove rewarding in several respects. Not only does Clarke provide a clear challenge to a non-substantial model of individuality by explicitly formulating and defending the objection that Whitehead’s system only allows for an attenuated conception of macroscopic individuality, Clarke’s own dynamic interpretation of the classical notion of substance seriously calls into question the very need for Whitehead’s “process turn” toward what Clarke sees as a misguided metaphysical atomism. Thus, engaging Clarke’s objection provides a valuable opportunity not only to evaluate the adequacy of his dynamic notion of substance, but also to respond to the common criticism that Whitehead’s system does not do justice to the unity of macroscopic individuals.

Kripke holds the thesis that identity statements containing natural kind terms are if true, necessarily true; these statements can be denominated theoretical identities. Kripke alleges that the necessity of theoretical identities grounds on the linguistic feature that natural kind terms are rigid designators. Nevertheless, I argue that the conception of natural kind terms as rigid designators, in one of their most natural views, hinders the establishment of the truth of theoretical identities and thus of their necessity. However, in Kripke’s works (...) another proposal, not linguistic but metaphysical, is found to justify the presumed necessity of theoretical identities; it grounds on essentialism concerning natural kinds. In this regard, I question some of Kripke’s main claims, focusing on one of the main examples of theoretical identities put forward by Kripke, i.e., “Water is H2\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$_2$$\end{document}O”. I challenge his a priori claims concerning what should be the essence of a natural kind like water. Furthermore, I adduce that the character of that theoretical identity is not that claimed by Kripke, since in the term flanking the right side of the identity sign it has to be resorted to the notion of similarity or it should have the form of a disjunction of a cluster of substances.

How could the self be a substance? There are various ways in which it could be, some familiar from the history of philosophy. I shall be rejecting these more familiar substantivalist approaches, but also the non-substantival theories traditionally opposed to them. I believe that the self is indeed a substance—in fact, that it is a simple or noncomposite substance—and, perhaps more remarkably still, that selves are, in a sense, self-creating substances. Of course, if one thinks of the (...) notion of substance as an outmoded relic of prescientific metaphysics—as the notion of some kind of basic and perhaps ineffablestuff—then the suggestion that the self is a substance may appear derisory. Even what we ordinarilycall‘stuffs’—gold and water and butter and the like—are, it seems, more properly conceived of as aggregates of molecules or atoms, while the latter are not appropriately to be thought of as being ‘made’ of any kind of ‘stuff’ at all. But this only goes to show that we need to think in terms of a more sophisticated notion of substance—one which may ultimately be traced back to Aristotle's conception of a ‘primary substance’ in theCategories, and whose heir in modern times is W. E. Johnson's notion of the ‘continuant’. It is the notion, that is, of a concrete individual capable of persisting identically through qualitative change, a subject of alterable predicates that is not itself predicable of any further subject.

In the Metaphysics , Aristotle examines the various meanings of concludes that its proper and primary meaning is “that which has predicates and is not predicated of anything else.” My aim in this paper is to accept this as an account of the notion of “substance,” and to free it from confusion with other notions, and then to consider whether when it is thus freed any “problem of substance” remains. I shall illustrate from the classical treatments of (...) the subject both the confusions and the development of a clearer view because it has seemed to me that exposition and criticism of those authorities sometimes show the same obscurities as the authorities themselves.

abstract: The notion of force is at the heart of Leibniz’s metaphysics. One of his central theses is that powers are to be reconceived as forces. Connectedly, he maintains that force is essential to the very account of substance. The paper contends that these claims have not been well understood due to an inadequate understanding of the notion of force itself. Against a common reading, I argue that Leibnizian force is not fundamentally dispositional, but an activity. Taking (...) seriously this idea means reconsidering not only the nature and function of powers, but also the basic character of Leibniz’s metaphysics—including his view of substances as soul-like and as causally independent. This paves the way for a novel interpretation of the unity of physical and metaphysical forces. (shrink)

This thesis argues that Metaphysics ZH$\Theta$--the crux of Aristotle's metaphysics--are not, as the tradition takes it for granted, a unity which hosts a consistent doctrine of substance; rather they contain two distinct approaches to substance. I call them respectively the formal approach and the synthetical approach. They present two kinds of hylomorphism, with Z17 as a demarcation. ;The formal approach takes form or essence as a separate substance from matter and the composite and demonstrates that form is (...) the primary substance over them. In this approach Aristotle views form or essence to be an essential property of an individual material substance. The locus of this approach is mainly in Z3-16 which host two conflict schemes for avoiding Plato's Third Man Argument. One is in Z7-9 which claims that form as primary should be toionde and not separate, and the other is in the program outlined in Z3 which rejects the notion of the Categories that primary substance is primary subject and proposes that it should be tode ti and separate. Each of these two schemes has internal difficulty. The former's claim that substance is universal is criticised in Z13, and the latter's claim that substance is particular is in conflict with the universality of knowledge. Thus the formal approach is an aporematic investigation into the ontological status of form on the basis of the dichotomy of tode ti-toionde. ;The synthetical approach associates the matter/form relation with the potentiality/actuality relation. Form and matter become relative conceptions, and are not separated from each other in definition. In this approach, Aristotle views form or essence to be the formal cause or the unifying principle which makes the material substance a unity rather than a heap. The locus of this approach is Z17 and H$\Theta$. ;The formal approach leads to the science of being qua being , and the synthetical approach leads to theology . Since two approaches are distinct, Aristotle's two notions of first philosophy cannot be reconciled. (shrink)

In a 1990 lecture Alasdair MacIntyre identified a number of difficulties in dialogue between philosophers of the Aristotelian and Thomist schools and those of certain modern schools. An examination of various interpretations of Aquinas reveals not only difficulties for inter-school dialogue but for intra-school dialogue as well. Even on foundational topics such as the notion of being, the proper method by which to study being, and the notion of substance, there are divergent opinions about what Aquinas held. (...) This essay argues that certain concepts from Gadamer can be helpful on these disputes. In particular, Gadamer’s ideas that to be is to be manifested, that a perspective-free metaphysics is impossible, and that the relationship between text and performance can serve as a model for understanding the relationship between substance and accident may help to resolve certain internecine disputes within the Aristotelian and Thomist schools as well as to foster philosophical conversation between these approaches and some contemporary schools of thought.

We aim to compile some means for a rational reconstruction of a named part of the start-over of Baruch (Benedictus) de Spinoza's metaphysics in 'de deo' (which is 'pars prima' of the 'ethica, ordine geometrico demonstrata' ) in terms of 1st order model theory. In so far, as our approach will be judged successful, it may, besides providing some help in understanding Spinoza, also contribute to the discussion of some or other philosophical evergreen, e.g. 'ontological commitment'. For this text we (...) assume the reader familiar with 'de deo' as well as with some basic concepts and results of 1st order model theory. Before we start reconstruction, we will first revisit shortly the concept of 'attributum' (definitio IV) in it's setting in 'de deo' , next scan for formalizable aspects of 'in suo genere finita' ('de deo', definitio II), subsequently list the model theoretic constructs we will make use of. Then we begin reconstruction by stating "coordinative definitions" for the notions of 'attribute (of a substance)', 'modus (as conceived via an attribute)' and 'substance (as conceived via an attribute)', reasoning shortly for each of them. The "coordinative definitions", we will arrive at, must not be understood as literal translations of Spinoza's concepts - of course, there can't be such a thing as a literal translation - they are meant as formal analoga of these concepts, mapping some logical structure. But even with this caveat they may seem strange to the reader at this stage of discussion. Additional justification for them then should be found in our endeavour, to map some argumentation of Spinoza's proofs of some of his propositions from this starting point. -/- [ Version 1 of this paper originated from 2020-03-14.

Millikan's account of substance concepts is based on a notion of “substance” expanded from realist notions of individuals and natural kinds. Her metaphysical notion, based on “inductive potential,” is shown to be too puristic and needs to incorporate cognizing subjects. This could preserve the realist/nondescriptionist insight that the extension of substances is determined by the world.

Kant’s philosophy of natural science has traditionally concentrated on a host of issues including the role of laws of nature and teleological judgements. However, so far, the literature has made virtually no contact with the no less important tradition in Kant’s legal and political philosophy. This article explores one aspect of such connection in relation to the normative foundations of Kant’s notion of cosmopolitan right. I argue that Kant’s argument for cosmopolitan right is based on two main premises: the (...) first is what I call thelaw of equilibrium, and the second is thepremise of physical interaction(commerciumin Latin) at work behind what Kant called the original ‘community of land’. The article argues that the relevant notion of community quacommerciumshould be understood in the context of Kant’s metaphysics of nature as a ‘real community of substances’ governed by a dynamical law of equality of action and reaction. This metaphysical-causal interpretive reading has far-reaching implications for the foundations of cosmopolitan right and its scope of applicability well beyond Kant’s envisaged right to universal hospitality.

The paper examines the connection between Aristotle's theory of generated substance and his notion of potentiality in "Metaphysics" Θ.7. Aristotle insists that the matter of a substance is not what that substance is, against a competing view that was widely held both in his day and now. He coined the term thaten (ἐ[unrepresentable symbol]νινονον) in order to make this point. The term highlights a systematic correspondence between the metaphysics of matter and of quality: the relationship between (...) a thing and its matter is like the relationship between a qualified thing and the relevant quality. It is argued that Aristotle's view about the matter of particular substances is connected with his view about ultimate matter. His conception of the matter of particular substances allows him to block an argument, from Plato's "Timaeus", that ultimate matter must be something imperceptible and lacking all perceptible qualities. Aristotle uses the term thaten to introduce an alternative conception of ultimate matter on which ultimate matter might well be an ordinary perceptible kind of thing. (shrink)

In Spinoza’s substance monism, radically different attributes constitute the essence of one and the same substance qua a strongly unified whole. Showing how this is possible poses a formidable Cartesian challenge to Spinoza’s metaphysics. In this paper I suggest a reconstruction of Spinoza’s notion of substance that meets this challenge and explains a major feature of this notion. I then show how this reconstruction can be used to resolve two fundamental problems of the Cartesian framework (...) that pertain to Spinoza’s metaphysics. On this basis, I then explain two further major features of Spinoza’s notion of substance. While my suggested reconstruction has all these advantages and accords well with Spinoza’s conceptual framework, it goes beyond what he explicitly says concerning substance monism. It is in the spirit of his metaphysical framework rather than in its letter. Thus, all I intend to show is that Spinoza has the conceptual resources for coming to terms with some of the deep problems that beset his metaphysics. (shrink)

Spinoza searched for a language that could help him to create a monistic system of ethics. Latin was in the 17th century a fairly malleable medium of communication. In its philosophical use it was largely a creation of Descartes. Spinoza wanted to use it in a way that would resemble Euclid's treatment of geometry. He needed a language that would clearly and precisely describe the process by which a man could liberate himself from the power of affection that hamper naturaly (...) propensity for social peace and mental equaenimity. He decided to begin by describing nature, which was responsible for man's proclivities and abilities. Consequently he needed a new conception of substance which on the one hand could be definied by some initial axioms, and on the other hand would sufficiently flexible to include various aspects of human thought. It is interesting that when Spinoza had to make a choice between flexibility and content, he resolved to adopt a strict method of reasoning at the cost of the received understanding of substance. It is possible that these linguistic considerations led him to adopt the view that substance is identical with God and as such encompasses all principles of operations of the human mind and premises for the deriving of all fundamental notions popular in his times.

This paper deals with the Aristotelian notion of topical matter mentioned in a few passages of the Metaphysics and ascribed to the celestial bodies. Taking into account the metaphysical context of each occurrence of this notion, it tries to determine for what metaphysical use this notion has been developed and what impact it has on the ousiological analysis of the celestial substances. It suggests that the notion of topical matter, although intended to provide a (...) convenient tool that makes possible a metaphysical, i.e. universal study of sensible substances, by allowing to subordinate every sensible substance to similar principles, in fact prevents celestial substances from being defined as ordinary hylomorphic compounds and leads to conceive them as a particular type of substances.

These lectures, delivered as part of the 1962 St. Augustine Lecture Series at Villanova University, develop the Thomistic conception of man as an "intellectual soul" which itself is both a self-subsisting substance and a substantial form. So viewed, man's unity consists in being a composite reality, not in the sense of a soul and a body functioning as co-parts of a whole, but in the sense of an intelligible substance which requires an organic body to realize its own (...) nature. The lectures neither criticize nor explicitly defend these claims but rather present them as a novel interpretation of man. This Aquinas was able to construct by drawing the conceptual tools of form, matter and substance from Aristotelian metaphysics and the view of man as an historical pilgrim from Augustinian theology.--B.

This volume gathers twelve essays by David Wiggins in an area where his work has been particularly influential. Among the subjects treated are: persistence of a substance through change, the notion of a continuant, the logic of identity, the co-occupation of space by a continuant and its matter, the relation of person to human organism, the metaphysical idea of a person, the status of artefacts, the relation of the three-dimensional and four-dimensional conceptions of reality, and the nomological (...) underpinning of sortal classification. From a much larger body of work the author has selected, edited or annotated, and variously shortened or extended eleven pieces. He has added an Introduction and one completely new essay, on the philosophy of biology and the role there of the idea of process. (shrink)
