Heraclitus uses paradoxical language to present the relationship between opposites in his worldview. This mode of expression has generated much controversy. Some take the paradoxes as evidence of a contradictory identity of opposites (Barnes), while others propose a dynamic union through transformation without identity that avoids the contradiction (Graham). By examining B88 and B62, I seek to identify the stronger and weaker points of such readings. The contradictory identity reading thwarts the transformation between opposites. The dynamic reading offers a plausible (...) alternative. However, it skips a characterization of how Heraclitus conceives of the transformation between opposites in physical terms. To fill this gap, I consider Heraclitus’ use of what I call the anti-cognate internal object in B62. I argue that ‘living the death and dying the life’ is a case of change as mixture, a popular conception among the early Presocratics. Upon closer examination, the anti-cognate internal object suggests that real contradictions belong to Heraclitus conception of change. The details reveal a philosophically compelling view. (shrink)

In a number of papers, Kit Fine introduced a theory of embodiment which distinguishes between rigid and variable embodiments, and has been successfully applied to clarify the ontological nature of entities whose parts may or may not vary in time. In particular, he has applied this theory to describe a process such as the erosion of a cliff, which would be a variable embodiment whose manifestations are the different states of erosion of the cliff. We find this theory very powerful, (...) and especially appropriate to capture the intuition that the same process may go on at different times. However, its formal principles have been subject to some criticisms, mainly concerning the mereological structure of a variable embodiment. Moreover, since the notion of variable embodiment is very general, simply saying that processes are variable embodiments is not enough to understand their ontological nature. To address these concerns, in this paper we proceed in two phases: first, we propose a revised version of Fine’s original theory adapted to the case of processes, which adopts a classical mereology instead of Fine’s hylomorphic mereology, and a temporalized constitution relation in place of Fine’s function of variable embodiment; second, we go deeper into the ontological nature of processes by revisiting the notions of homogeneity, intentionality, and telicity discussed in the literature, and propose an account based on ontological principles and not on semantic properties of predicates. This allows us to organize processes into a novel taxonomy based exclusively on their unity and individuation principles. (shrink)

Monists and pluralists disagree concerning how many ordinary objects there are in a single situation. For instance, pluralists argue that a statue and the clay it is made of have different properties, and thereby are different. The standard monist’s response is to hold that there is just a single object, and that, under the description “being a statue”, this object is, e.g., aesthetically valuable, and that, under the description “being a piece of clay”, it is not aesthetically valuable. However, Fine (...) provided an ontological reading of the expression “an object under a description”: the theory of rigid embodiments. The debate between monists and pluralists reduplicates in the domain of ordinary occurrences, like walks and conferences. Specifically, they disagree whether an occurrence in progress (also called “process”) like John’s walk that is happening at tn is identical to some completed occurrence (also called “event”) like John’s walk that happened between, e.g., t1 and tn. Under the adoption of the pluralist’s position, the article aims to provide a novel theory of ordinary occurrences that develops the ontological reading of “under a description” to account for occurrences in progress and completed occurrences. As a first result, we formulate a theory according to which both occurrences in progress and completed occurrences are rigid embodiments. As a second result, we argue that the suggested theory is explanatorily powerful to the extent it solves two puzzles that we call “the Puzzle from the Completion of a Process” and “the Metaphysical-cum-Semantical Puzzle”.

Several disputes about the nature of experience operate under the assumption that experiences have parts, including temporal parts. There's the widely held view, when it comes to temporal experiences, that we should follow James' exhortation that such experiences aren't mere successions of their temporal parts, but something more. And there's the question of whether it is the parts of experiences which determine whole experiences and the properties they have, or whether the determination goes instead from the whole to the parts, (...) as holists have it. But what are parts, or temporal parts, of experiences exactly—what does it mean to say that an experience is “part” of another? Are the participants in those disputes talking about the same thing—is there a univocal notion of “experiential part” available? Are there different kinds of experiential parts? And if there are, is there a systematic way of carving them out? More importantly, how should we conceive of the temporal parts of experiences, and how can we establish that experiences really do have temporal parts, against those who reject the notion? (shrink)

The theory of variable embodiments has been primarily formulated to model ordinary objects as things that change their parts over time. A variable embodiment /f/ is a sui generis whole constructed from a principle f, the principle of a variable embodiment, and it is manifested at different times by different things picked out by such a principle f. This principle is usually clarified as a function that picks out, at any given time the variable embodiment exists, its corresponding manifestation at (...) that time, and it fails to pick out anything at any other time. The first purpose of this article is to examine and refute three natural understandings of such a principle. Specifically, first, we argue against the view that it should be understood extensionally as either a partial function or total function. Next, we provide some motivations to reject the understanding of the principle as a function in intensional terms, where the notion of intension is analyzed in terms of a specific version of a possible world semantics. The second goal of the article is to make it plausible that the principle has an intensional character and, on the basis of the results achieved, to formulate some constraints that an account of such a principle should meet.

According to Aristotle, the present is an indivisible instant, or now. Aristotle holds that present-tense movement claims are sometimes true, but he argues that nothing ‘kineitai’ (moves/is moving) in the now. He characterizes movement as something that is ‘incomplete’ while it is occurring. My paper is an attempt to understand this combination of views. I draw a contrast between Aristotle’s position and an alternative view (defended by certain modern philosophers, but also by Plotinus), on which a present-tense movement claim is (...) made true by the existence of something that is wholly present in the now. And I give some reasons for preferring Aristotle’s position. (shrink)

The present PhD dissertation aims to examine the relation between modality and change in Aristotle’s metaphysics. -/- On the one hand, Aristotle supports his modal realism (i.e., worldly objects have modal properties - potentialities and essences - that ground the ascriptions of possibility and necessity) by arguing that the rejection of modal realism makes change inexplicable, or, worse, banishes it from the realm of reality. On the other hand, the Stagirite analyses processes by means of modal notions (‘change is the (...) actuality of what is virtual insofar as it is virtual’). In other words: to grasp what change is, one has to resort to the modal idiom of potentialities, while the fact that there is change is indicative of the fact that nature is full of modal properties. -/- Aristotle’s modal and kinetic realism finds a negative in the figure of the Megaric Diodorus Kronus. The polemical situation of Greek philosophy has indeed the dialectical advantage of not opposing the Aristotelian position to a sui generis straw man. Both in its reduction of modal judgements to temporal quantifications and in its dissolution of the reality of the state-of-being-in-motion in favour of a cinematographic view of processes, the philosophical figure of reductionist antirealism embodied by Diodorus constitutes an alternative that takes the opposite view of Aristotle’s realism. -/- The present study is structured as a discussion between these two positions. In the face of Diodorus’ antirealist challenges, Aristotle articulates modal and kinetic considerations: the answers he gives to Diodorus’ puzzles thus provide valuable insight into his metaphysics. Moreover, the examination of Aristotle’s and Diodorus’ metaphysics, because of their insight and originality, will not fail to interest the philosopher concerned with the metaphysical foundations of modern physics, insofar as the entanglement between modalities and processes is nowadays at the core of mechanics (phase spaces, path integrals, etc.).

In this paper, I propose a theory of living organisms that captures the insights of both traditional Aristotelian hylomorphism and John Dupré's “biological processualism”. Like traditional Aristotelian hylomorphism, the proposed theory understands material objects to be comprised of both matter and form. Unlike contemporary structural varieties of hylomorphism, however, it does not understand the form of a material object to be a relation, configuration, or structure exhibited by its parts but an activity or process in which its matter is continuously (...) engaged. Following Mark Steen, I call the proposed theory “Hyloenergeism”. As a version of hylomorphism, hyloenergeism better captures the inherent dynamism of living organisms than contemporary structural approaches. And it does so not by abandoning the substantialist paradigm, as Dupré's biological processualism does, but by reconceptualizing the nature of material substances as possessing a processual core. Hyloenergeism, then, paves a middle way for those looking for a substance view of living organisms sensitive to the concerns raised by contemporary processualist philosophers of biology. (shrink)

Causal Dispositionalism provides an account of causation based on an ontology of causal powers, properties with causal essence. According to the account, causation can be analysed in terms of the interaction of powers and its subsequent production of their effect. Recently, Baltimore, J. A. has raised a challenge against two competing approaches, the compositional view and the mutual manifestation view, to explain what makes powers interactive – the interaction gap. In this paper, we raise the challenge of explaining what makes (...) powers productive – the production gap. While Baltimore’s verdict is tentatively favouring, we find both approaches wanting. Our conclusion is that Causal Dispositionalists should take Baltimore’s and our critique seriously. Powers cannot cause their effects just by bearing the name “causal”. To deserve their names, more metaphysical details are needed. (shrink)

Este trabajo examina si la pregunta “¿puede pensar una máquina?” ha sido respondida de manera satisfactoria. La primera sección, justamente, examina el dictum cartesiano según el cual una máquina no puede pensar en principio. La segunda trata sobre una rebelión en contra de Descartes, encabezada por Babbage. A su vez, la tercera describe una segunda rebelión encabezada por Turing. En ambas se examina, primero el lenguaje mentalista/instrumentalista para describir a una máquina programada y segundo, el reemplazo de la pregunta por (...) el Juego de la Imitación. En la cuarta sección sostengo que la evidencia aportada por dicho juego nos devuelve a la pregunta, pese a Turing. Por último, la quinta sección versa sobre cómo la Habitación China de Searle, paradójicamente, apoya el dictum cartesiano, y lo hace porque tal experimento mental se basa en una capacidad mental falible: la introspección. Se concluye que la pregunta acerca de si puede pensar una máquina es derivada de otra pregunta filosófica compleja: la de la naturaleza de lo mental y el problema mente-cuerpo. (shrink)

In this paper I argue that even the most radical metaphysics of powers (such as that adopted by Mumford & Anjum, Cartwright, or Groff) are compatible with eternalism. I first offer a taxonomy of powers ontologies, and attempt to characterise the difference between moderate and radical powers ontologies – the latter are characterised by an emphasis on production and dynamicity. I consider an argument by C. Friebe to the effect that the productive character of powers is inconsistent with Eternalism and (...) find it wanting. I then elucidate the notion of dynamicity that radical powers theorists employ by making apparent their link with an ontology of irreducible processes. Finally, I respond to an argument by Donatella Donati to the effect that eternalism entails a reductive account of change which is inconsistent with process ontologies, and show that the the two are compatible. I conclude that we have no reason to think that radical powers metaphysics (and, a fortiori, every powers ontology) are not compatible with eternalism. (shrink)

Persistence in Time No person ever steps into the same river twice—or so goes the Heraclitean maxim. Obscure as it is, the maxim is often taken to express two ideas. The first is that everything always changes, and nothing remains perfectly similar to how it was just one instant before. The second is that nothing … Continue reading Persistence in Time →.

Here, I lay the foundations of a high-level ontology of particulars whose structuring principles differ radically from the 'continuant' vs. 'occurrent' distinction traditionally adopted in applied ontology. These principles are derived from a new analysis of the ontology of “occurring” or “happening” entities. Firstly, my analysis integrates recent work on the ontology of processes, which brings them closer to objects in their mode of existence and persistence by assimilating them to continuant particulars. Secondly, my analysis distinguishes clearly between processes and (...) events, in order to make the latter abstract objects of thought (alongside propositions). Lastly, I open my ontological inventory to properties and facts, the existence of which is commonly admitted. By giving specific roles to these primitives, the framework allows one to account for static and dynamic aspects of the physical world and for the way that subjects conceive its history: facts account for the life of substances (physical objects and processes), whereas events enable cognitive subjects to account for the life story of substances.

The distinction between occurrent and non-occurrent mental states is frequently appealed to by contemporary philosophers, but it has never been explicated in any significant detail. In the literature, two accounts of the distinction are commonly presupposed. One is that occurrent states are conscious states. The other is that non-occurrent states are dispositional states, and thus that occurrent states are manifestations of dispositions. I argue that neither of these accounts is adequate, and therefore that another account is needed. I propose that (...) occurrent states are active states. (shrink)

In this paper, I explore the question what a continuant is, in the context of a very interesting suggestion recently made by Rowland Stout, as part of his attempt to develop a coherent ontology of processes. Stout claims that a continuant is best thought of as something that primarily has its properties at times, rather than atemporally—and that on this construal, processes should count as continuants. While accepting that Stout is onto something here, I reject his suggestion that we should (...) accept that processes are both occurrents and continuants; nothing, I argue, can truly occur or happen, which does not have temporal parts. I make an alternative suggestion as to how one might deal with the peculiar status of processes without jettisoning a very natural account of occurrence; and assess the consequences for the category of continuant.

A critical survey of the main philosophical theories about events and event talk, organized in three main sections: (i) Events and Other Categories (Events vs. Objects; Events vs. Facts; Events vs. Properties; Events vs. Times); (ii) Types of Events (Activities, Accomplishments, Achievements, and States; Static and Dynamic Events; Actions and Bodily Movements; Mental and Physical Events; Negative Events); (iii) Existence, Identity, and Indeterminacy.

We regularly talk of the experience of time passing. Some theorists have taken the supposed phenomenology of time passing to provide support for metaphysical accounts of the nature of time; opposing theorists typically granted that there is a phenomenology of time passing while seeking to dispute that any metaphysical conclusions about time can be drawn from this. In recent debates theorists have also begun to dispute that there is a phenomenology of time passing – plausibly, if there is not, then (...) there is no relevant experience to be explained away, or for metaphysical conclusions to be drawn from. In the present paper I offer one explanation of why such disputes about the experience of time passing may seem intractable. However, I suggest that there is a distinct and more tractable issue lurking in this area, concerning our experience of how certain phenomena persist over time. Interestingly, articulating how we experience different phenomena as persisting over time doesn't simply provide a challenge to one metaphysical view of persistence rather than another; instead, it generates an explanatory challenge for a variety of competing views of persistence and, by extension, a challenge for popular combinations of views of the metaphysics of persistence and of time.

This thesis develops an account of the nature of wakeful consciousness. Its principal suggestion is that wakeful consciousness is a biological phenomenon and should thus be placed in the context appropriate to biological phenomena. That context is the characterizing form of life of organisms. Once wakeful consciousness is assigned its place in this context, it emerges that wakeful consciousness is a teleological phenomenon, one that is to be understood as having the proper function of putting its bearer in touch with (...) the world. What emerges from reflection on the metaphysics of organisms is an account of wakeful consciousness that is teleological in character but which does not fall foul of the strictures of physicalism and casts new light on recent philosophical debates about consciousness.

Processes produce changes: rivers erode their banks and thunderstorms cause floods. If I am right that organisms are a kind of process, then the causally efficacious behaviours of organisms are also examples of processes producing change. In this paper I shall try to articulate a view of how we should think of causation within a broadly processual ontology of the living world. Specifically, I shall argue that causation, at least in a central class of cases, is the interaction of processes, (...) that such causation is the exercise of a capacity inherent in that process and, negatively, that causation should not be understood as the instantiation of universal laws. The approach I describe has substantial similarities with the process causality articulated by Wesley Salmon and Phil Dowe for physical causation, making it plausible that the basic approach can be applied equally to the non-living world. It is an approach that builds at crucial points on the criticisms of determinism and universal causality famously articulated by Elizabeth Anscombe. (shrink)

A popular claim in recent philosophy of mind and action is that events only exist once they are over. This has been taken to have the consequence that many temporal phenomena cannot be understood ‘from the inside’, as they are unfolding, purely in terms of events. However, as I argue here, the claim that events exist only when over is incoherent. I consider two ways of understanding the claim and the notion of existence it involves: one that ties existence to (...) the logic of quantification, and another that assimilates the existence of an event to that of a continuant. The first of these, I argue, cannot be the right way to understand the target claim, as there are serious logical obstacles to regarding this notion of existence as temporally variable. The second, on the other hand, leaves it ultimately mysterious what the existence of an event could amount to. I close with the suggestion that the undeniable temporal asymmetries which parties to the debate are interested in are properly understood in perspectival, not ontological, terms. (shrink)

In recent years, there has been a raising interest in the metaphysics of processes and events. However, what are we debating about when we debate about processes and events? Such an answer has received three main answers that are mutually incompatible. The situation is worrisome: if philosophers don’t even agree on how to individuate process expressions and distinguish them from event expressions, how can one compare two metaphysical theories of processes and events? In this article, I aim to answer to (...) such questions. First, I propose a revised version of Vendler and Kenny’s account. Then, I distinguish a linguistic part and an ontological part for each of the three approaches. On the one hand, I argue that the ontological parts constitute not-compelling theses; on the other hand, I make it plausible that the linguistic parts are mutually consistent. Such results contribute to address the initial questions: when we speak about processes and events, we are speaking about a plurality of phenomena characterized through the integration of the linguistic parts of the accounts considered. Moreover, these linguistic parts, taken together, provide data that any adequate metaphysical theory of processes and events has to account for. (shrink)

Processes are occurrents that were, are, or will be happening. Moreover, either they endure (i.e., they continue) or they perdure. Stout [11] contends that they endure. His argument – the Change Argument, hereafter – is grounded in the claims that processes may change and that something may change if and only if it endures. I shall argue that the Change Argument does not succeed. In particular, I shall show that, if the Change Argument aims at being neutral between endurantism and (...) perdurantism, then it is invalid. If, instead, his argument rejects the constraint of neutrality in favor of the assumption of endurance theory for processes, then it is valid, but circular. In either case, Stout’s Change Argument fails to establish that processes endure. (shrink)

A crucial question for a process view of life is how to identify a process and how to follow it through time. The genidentity view can contribute decisively to this project. It says that the identity through time of an entity X is given by a well-identified series of continuous states of affairs. Genidentity helps address the problem of diachronic identity in the living world. This chapter describes the centrality of the concept of genidentity for David Hull and proposes an (...) extension of Hull’s view to the ubiquitous phenomenon of symbiosis. Finally, using immunology as a key example, it shows that the genidentity view suggests that the main interest of a process approach is epistemological rather than ontological and that its principal claim is one of priority, namely that processes precede and define things, and not vice versa.

This paper aims to motivate a new beginning in metaphysical thinking about persistence by drawing attention to the disappearance of change in current accounts of persistence. I defend the claim that the debate is stuck in a dilemma which results from neglecting the constructive role of change for persistence. Neither of the two main competing views, perdurantism and endurantism, captures the idea of persistence as an identity through time. I identify the fundamental ontological reasons for this, namely the shared commitment (...) to what I call ‘thing ontology’: an ontology that gives the ontological priority to static things. I conclude by briefly indicating how switching to a process ontological framework that takes process and change to be ontologically primary may allow for overcoming the dilemma of persistence.

Many contemporary proponents of hylomorphism endorse a version of hylomorphism according to which the form of a material object is a certain kind of complex relation or structure. Structural approaches to form, however, seem not to capture form’s traditional role as the guarantor of diachronic identity, since more “dynamically complex” material objects, such as living organisms, seem to undergo, and survive, various structural changes over the course of their existence. As a result, some contemporary hylomorphists have looked to alternative, non-structural (...) approaches to form. One of the leading non-structural approaches is the powers approach, according to which the form of a material object is a certain kind of power continuously activated in the object or in its material parts. In this paper, I begin by offering an overview and assessment of this powers approach to form. I argue that while the powers approach captures some crucial elements for understanding the nature of more dynamically complex material objects, when we press on the details of the view we find that it actually points to a related, but importantly distinct, third approach to understanding form, according to which the form of a material object is a certain kind of activity or process in which the material object or its parts are continuously engaged. I call this third approach “Hyloenergeism”. In the second half of the paper, I consider what such a view of material objects might look like and what its principal virtues might be. (shrink)

Numerous authors have attempted to carve an ontological distinction between events and processes on the basis of a widely noted linguistic datum involving count and mass nouns, where events are thought to be analogous to countable objects while processes to non-countable stuff. By assessing the most developed of these proposals—that of Helen Steward’s—this paper locates the motivations behind the project of carving some such distinction between events and processes, and proceeds to offer considerations toward an alternative account of processes—one whose (...) ontology is more akin to that of states than it is to stuff.

John goes out for a walk. If John endures and his walk perdures, they are different entities. However, what if both John and his walk perdure? Is John’s walk identical to his relevant temporal part? Some philosophers answer in the affirmative. Their motivations rest on ontological parsimony and the quest for clear-cut identity criteria for existing things. By contrast, one of the most widely accepted theories of events – the theory of events as property-exemplifications – allows us to formulate an (...) argument to the effect that objects’ temporal parts are distinct from the events they participate in: the AID argument, as I shall call it. In this paper, I argue that accepting austere nominalism is the best strategy a supporter of the identification between events and temporal parts of objects can take in order to resist the AID argument. (shrink)

The theory of events as property-instances has been considered one of the most widely accepted metaphysical theories of events. On the other hand, several philosophers claim that if both events and objects perdure, then objects must be identified with events. In this work, I investigate whether these two views can be held together. I shall argue that if they can, it depends on the particular theory of instantiation one is to adopt. In particular, I shall conclude that the theory of (...) events as property-instances and the view that identifies objects with events can be held together only if instances of eventive universals are temporal parts of objects – namely, those temporal parts that have the universals in question.

I agree with a great deal in Helen Steward's paper. I am especially sympathetic to her suggestion that we gain metaphysical illumination by considering various ways in which we arrive at ideas of certain kinds of individuals by abstraction from those of more basic kinds. My aim is to pursue that suggestion by exploring the proposal that a grounding node in this form of abstraction may be characterized by Exclusivity in spatial location. Steward claims that we arrive at our ideas (...) of specific events and processes by different modes of abstraction in cases where a more basic persisting individual undergoes some kind of change. I argue that the most basic individuals in this hierarchy of abstraction are enduring substances that occupy their spatial location exclusively at all times: no two such substances are ever precisely collocated.

We examine the intentional processes that correspond to conceptualizations of activities performed by subjects with the intention of achieving an objective. Taking as its basis a general framework of intentional processes, two types of such process are considered: epistemic ones, aimed at acquiring knowledge about something, and poietic ones, aimed at bringing about something. The “something” is understood as anything that the processes can pertain to: a physical, mental or abstract object, a phenomenon, a state of affairs, etc. The generic (...) features of such processes are discussed, with focus on: features that are common for epistemic and poietic intentional processes as well as on features that differentiate them, the dynamic and static features of the processes, and on issues involved in controlling the progression of the processes towards intended objectives. The latter issue is the essential part of our considerations, the two former establish the necessary conceptual framework. The presented analysis aims at shedding light on these aspects of human intentional activities which can be considered virtually independent of any specific area of human intentional activity, be it natural sciences, humanities or technology.
