Annotated bibliography part 1: process ontology 1996a "Individuen als Prozesse: Zur prozeß-ontologischen Revision des Substanzparadigmas," Logos 5 (1995), 303-343. The paper presents in outline a program of ontological revision, arguing both a methodological thesis in favour of a pluralist-constructional conception of ontology, and a substantive thesis in favour of a process ontology. Working from case studies in the contemporary debate about numerical, qualitative, and transtemporal identity, I identify six deep-seated substance-ontological presuppositions. Using the negations of these presuppositions as constructional heuristics I sketch the outline of a new ontological scheme based on processes or “dynamic masses.” As I try to show in the paper’s last section, the theory of dynamic masses offers new and promising routes to undercut the characteristic dichotomies in the debate about individuation, universals, and persistence. 1996b: "Non-countable Individuals: Why One and the Same Is Not One and the Same," Southwest Philosophy Review 12 (1996), 225-237. It is a common presupposition in ontology (metaphysics) that a so-called 'principle of individuation' amounts to a principle of counting. Against this presupposition I argue that the predicates 'x is the same individual as y' and 'x is one with y' are neither co-extensional nor co-intensional. Non-countable entities such as masses or stuffs (or the referents of nouns in classifier languages) also fulfill the requirements of individuality. I suggest that Leibniz' 'principle of the identity of indiscernibles' (PII) should be taken as a principle of individuality, rather than as a principle of the individuality of countables. 1996d, "Existence in Time: From Substance to Process," in: Perspectives on Time. Boston Studies in Philosophy of Science, ed. by J. Faye, U. Scheffler, M. Urs, (Dordrecht: Kluwer), 143-182. Contemporary analytical ontology, to a large extent, is still committed to basic assumptions of the substance-ontological tradition. The contemporary discussion about transtemporal identity or persistence in particular still proceeds from within a framework of substance-ontological principles which largely remain implicit. These implicit premises or presuppositions of the debate impose problematic constraints on ontological accounts of persistence. I identify five of these formative principles and show how they enter the discussion about endurantist and perdurantist explanations of persistence. I then offer a new explanation of persistence that abandons the mentioned problematic presuppositions, operating within the framework of a new process ontology called 'Dynamic Mass Theory.' 2000d: "The Dynamic Constitution of Things," in: Faye, J. et al. (eds.), Facts and Events. Poznañ Studies in Philosophy of Science. 72, 241-278. Due to its epistemological primacy the notion of a thing is the primary explanandum of any ontological theory of the language of common sense. In this paper I offer a tentative process-ontological definition of things within the framework of Dynamic Mass Theory (DMT). I begin by setting out the basic elements of DMT. First, deriving some motivational support from the linguistic phenomena of aspect shift I introduce the new category of (subjectless) activities or 'dynamic masses' Second, I sketch graphically how one might in DMT recategorize the classical categories, i.e., conceive of events, things, stuffs, properties and relations etc., as subtypes of dynamic masses. Third, I state some principles of the DMT mereology on activities, a non-standard mereology with a non-transitive part-relation. On the background of this brief overview over DMT I work dialectically towards a definition of the common sense notion of a thing. Things, I claim, are transportable countable particulars which serve a shapedependent function. I show that DMT can fairly smoothly accommodate this notion of thinghood. In conclusion I point at ways in which the sketched DMTaccount can contribute to a satisfying ontological treatment of the persistence and material constitution of things. 2002 “Quanta, Tropes, or Processes: On Ontologies for Quantum Field Theory,” in: Kuhlmann, M. et. al., (eds.) Ontological Aspects of Quantum Field Theory, World Scientific: Singapore, 53-93. My primary aim in this essay is to assist philosophers of science working on the ontological interpretation of QFT by highlighting some questionable assumptions imported into the debate from the ontological tradition. After some methodological preliminaries, I will state a set of presuppositions, ubiquitous within historical and current ontological research, which are by no means laws of thought but the contingent commitments of an ontological research tradition I call the ‘substance paradigm’. Some of these presuppositions, I argue, made their way into the debate about indistinguishability, particlehood, and individuality within the quantumphysical domain. This has the effect, among others, that philosophers of physics misrepresent the case of ‘indistinguishable particles’ as having decisive bearing on the question of whether ‘quantum particles’ are individuals or non-individuals. I then consider various extant and possible strategies of gaining an ontological interpretation of some core concepts of QFT by modifying the presuppositional depth-structure of the ontological tradition: P. Teller’s “quanta,” trope theory and Whitehead’s ontology of occasions, which each operate with concrete particular entities that are not individuals. But one might also take the opposite route. In the final section I sketch an ontology based on concrete individuals that are not particular entities, the theory of free processes (APT). APT is a genuinely new ontological scheme where a large number of traditional ontological presuppositions are rejected; in consequence it has a variety of features that prima facie would seem to allow for a straightforward application in quantumphysical domains. Whether this impression is justified remains to be seen; my primary aim here, to restate, is to argue not for a substantive but rather for a methodological thesis: that the ontological interpretation of QFT must pay critical attention to existing theoretical biases within ontology. 2004 " Processes and Particulars," in: Process Metaphysics, ed. by M. Weber, Ontos-Verlag, Frankfurt, 113-135. Despite his attempt to leave substance-ontology behind, Rescher operates with ‘processes’ which have the ‘classical’ combination of category features— they are concrete, countable, particular and determinate individuals. For this reason the “process theory of things” suggested in chapter 3 shares crucial shortcomings of its substance-ontological rivals. I argue, first, that Rescher has not shown how a process-based bundle theory of things could avoid the necessitarian commitments of a Leibnizian bundle theory. Second, I argue that the suggested process-based explanantion of persistence presents some improvements over common ‘perdurance’ accounts but, like the latter, cannot make sense of transtemporal identity statements, a crucial requirement for any satisfactory theory of persistence. That process-ontology has other options I show by contrasting Rescher’s particularist scheme with ‘free process theory’, a new process ontology that tries to stay clear of substance-ontological presuppositions. Free processes are ‘dynamic stuffs,’ combining categorial features of activities and stuffs: they are concrete yet non-particular, determinable individuals. In conclusion I sketch the treatment of persistence statements in free process theory to support my thesis that a process ontology is better off without ‘classical’ individuals. 2008 "Beyond Endurance and Perdurance: Recurrent Dynamics", in: C. Kanzian (ed.), Persistence.Ontos. Frankfurt. 121-153. The purpose of this paper is to introduce the reader to a new account of persistence developed within such a new ontological framework, General Process Theory (GPT), based on a new ontological category called general processes, or, less ‘technically,’ dynamics. Unlike other attempts to promote process-based descriptive frameworks, GPT is firmly committed to the methodology of analytical ontology. Within GPT, persistence is the strict identity or sameness in time of an entity that occupies a spatiotemporally extended region. Thus the new account straddles the traditional disjuncture between endurance and perdurance theories, but it does so in the sense of leaving both of these theory types behind, since it operates with a different notion of individuality that is not tied to particularity (i.e., necessary unique locatedness). To motivate the new approach I begin by highlighting some of the presuppositions that constrain the solution space for the ‘problem of persistence’ in questionable ways. Then I offer a sketch of the core ideas of General Process Theory, and finally I adumbrate how ontological counterparts (‘truth-makers’) for assertions about persistence and change can be formulated within this framework, highlighting some of advantages vis-à-vis extant endurance and perdurance accounts. 2009 "Forms of Emergence in General Process Theory", Synthese 166:479-512. General Process Theory (GPT) is a new (non-Whiteheadian) process ontology. According to GPT the domains of scientific inquiry and everyday practice consist of configurations of ‘goings-on’ or ‘dynamics’ that can be technically defined as concrete, dynamic, non-particular individuals called general processes. The paper offers a brief introduction to GPT in order to provide ontological foundations for research programs such as interactivism that centrally rely on the notions of ‘process,’ ‘interaction,’ and ‘emergence.’ I begin with an analysis of our common sense concept of activities, which plays a crucial heuristic role in the development of the notion of a general process. General processes are not individuated in terms of their location but in terms of ‘what they do,’ i.e. in terms of their dynamic relationships in the basic sense of one process being part of another. The formal framework of GPT is thus an extensional mereology, albeit a non-classical theory with a non-transitive part-relation. After a brief sketch of basic notions and strategies of the GPT-framework I show how the latter may be applied to distinguish between causal, mechanistic, functional, self-maintaining, and recursively self-maintaining interactions, all of which involve ‘emergent phenomena’ in various senses of the term. 2010 "Particulars", in: R. Poli, J. Seibt (eds.), Theory and Applications of Ontology, Vol. 1. Philosophical Perspectives, Springer. According to the standard view of particularity, an entity is a particular just in case it necessarily has a unique spatial location at any time of its existence. That the basic entities of the world we speak about in common sense and science are particular entities in this sense is the thesis of “foundational particularism,” a theoretical intuition that has guided Western ontological research from its beginnings to the present day. The main aim of this paper is to review the notion of particularity and its role in ontology. I proceed in four steps. First, I offer a brief reconstruction of the tasks of ontology as “theory of categorial inference in L”. An ontological theory states which (combinations of) entity types or categories make true L-sentences true; the features of the stipulated categories explain why L-speakers are entitled to draw certain material inferences from the classificatory expressions of L. Second, I draw attention to the fact that since Aristotle this theoretical program typically has been implemented with peculiar restrictions prescribing certain combinations of category features, e.g., the combination of particularity, concreteness, individuality, and subjecthood. I briefly sketch how these restrictions of the “substance paradigm” or “myth of substance” are reinforced by the standard readings of predicate-logical constants, viz. the existential quantifier and the identity sign. Third, I argue that in the context of the substance paradigm foundational particularism is incoherent. I discuss the current standard conceptions of particulars as developed in the debate about individuation (bare particulars, nude particulars, tropes) and show that their main difficulties derive from the traditional restriction that particulars are so also logical subjects and/or individuals. Fourth, to show that the traditional linkages of category features are not conceptual necessities, I sketch the outlines of an ontology (General Process Theory) based on non-particular individuals. For ontologists in computer science working with description logic this monocategoreal ontology based on more or less generic ‘dynamics’ may hold special interest. As General Process Theory documents, ontologists may well abandon the notion of particularity: in common sense and science we do reason about items that have a unique spatial location at any time, but the uniqueness of their location can be taken to be a contingent affair.
