Character, Objects and Properties Character, Objects and Properties Rory Clive Jubber University College London Thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy Department of Science and Technology Studies University College London 1 2 Signed Declaration I, Rory Clive Jubber confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. 3 4 To my mom Rose, my uncle Rob, my mentor Emma and that non-human animal Mable. 5 6 Abstract: The thesis sets out to accomplish three related tasks at different levels of generality. The first is articulating and defending two problems: The Problem of Resemblance and The Problem of Character, pushing for a shift of focus to the latter. The second level is to consider a general approach to dealing with these problems, the constituent ontology, with a focus on The Problem of Character. I argue that the constituent ontology is a valuable and coherent general approach to giving an answer to these problems. Finally, at the last level of the greatest degree of specificity, I consider particular versions of the constituent approach: one that takes properties to be non-mereological constituents of objects and the other that takes properties to be ontological parts of objects operating under a property mereology. I argue for the latter, which is known as the mereological bundle theory. I argue that this version of the constituent ontology offers a powerful theory of exactly how properties and objects are related by proper ontological parthood. I take the mereological bundle theory to offer the best systematic metaphysics of properties and objects, one that is not only metaphysically coherent but also one that accords well with empirical considerations on the nature of spacetime in physical science. If I am correct, then the world is nothing but a world of properties and fusions of those properties. 7 8 Research Impact Statement: The work contained in this thesis sets out to articulate and defend the general framework of the constituent ontology and then to articulate and defend a particular variant of it that I argue is the best, namely the mereological bundle theory. The constituent ontology has received little explicit focus until recent years. The aim of chapter 2 is to provide a framework to understand the rule of the game by which the constituent ontology is playing. Besides my own work, only Michael Loux has attempted to explicitly engage in this. Chapter 2 therefore contributes to the discussions in articulating the general framework of the constituent ontology. Chapter 3 then sets out to defend the constituent ontology. In particular I clarify Van Inwagen’s charge of incomprehensibility against the constituent ontology followed by my own defence against this charge. This introduces some new avenues in the defence of the constituent ontology. In chapter 5 my work on the mereological bundle theory offers some interesting contributions to the literature. The mereological bundle theory , has received less attention than it should have, with Laurie Paul being the primary exponent of the view. I argue in chapter 5 that not only does the mereological bundle theory offer a precise answer to the Problem of Character via properties being proper ontological parts but if offers a novel solution to the Problem of Resemblance. This solution takes properties to be universals but does not require properties to be wholly present at their instances. In addition, amongst other contributions to the topic, I also offer novel arguments that exponents of the mereological bundle theory should be fictionalists about spatiotemporal parts, that mereological bundle theory need not commit itself to any particular view on the nature of spacetime and I give a discussion around what I call the Problem of Indiscernible Fusions. From each of these novel elements of the thesis contained throughout I intend to prepare for publication a total of seven manuscripts intended for publication in eminent philosophy journals and continue to deliver these papers at philosophy conferences. In terms of future work on the topics contained in the thesis I intend to work to understand how properties as ontological parts feature in modality, causation , the laws of nature and dispositions. The mereological bundle theory has not received enough attention in the literature even with Laurie Paul’s publications on the topic. It often receives indirect 9 citation in discussions on properties and composition but too infrequently is more deeply explored. My intention , starting with this thesis, is to explore that space of metaphysical possibility. 10 11 Table of Contents Introduction .......................................................................... 17 Chapter 1.

Three Problems about the Science of Being qua Being ‘There is a science (epistêmê),’ says Aristotle, ‘which studies being qua being (to on hê(i) on), and the attributes belonging to it in its own right’ (Met. 1003a21–22). This claim, which opens Metaphysics IV 1, is both surprising and unsettling—sur- prising because Aristotle seems elsewhere to deny the existence of any such science and unsettling because his denial seems very plausibly grounded. He claims that each science (epistêmê) studies a unified genus (APo 87a39-b1), but he denies that there is a single genus for all beings (APo 92b14; Top. 121a16, b7–9; cf. Met. 998b22). Evidently, his two claims conspire against the science he announces: if there is no genus of being and every science requires its own genus, then there is no science of being. This seems, moreover, to be precisely the conclusion drawn by Aristotle in his Eudemian Ethics, where he maintains that we should no more look for a gen- eral science of being than we should look for a general science of goodness: ‘Just as being is not something single for the things mentioned [viz.

  • Vol. 3 No. 1 January – June, 2014 Page the QUESTION of “BEING”
    Vol. 3 No. 1 January – June, 2014 THE QUESTION OF “BEING” IN AFRICAN PHILOSOPHY Lucky U. OGBONNAYA, M.A. Essien Ukpabio Presbyterian Theological College, Itu, Nigeria Abstract This work is of the view that the question of being is not only a problem in Western philosophy but also in African philosophy. It, therefore, posits that being is that which is and has both abstract and concrete aspect. The work arrives at this conclusion by critically analyzing and evaluating the views of some key African philosophers with respect to being. With this, it discovers that the way that these African philosophers have postulated the idea of being is in the same manner like their Western philosophers whom they tried to criticize. This work tries to synthesize the notions of beings of these African philosophers in order to reach at a better understanding of being. This notion of being leans heavily on Asouzu’s ibuanyidanda ontology which does not bifurcate or polarize being, but harmonizes entities or realities that seem to be contrary or opposing in being. KEYWORDS: Being, Ifedi, Ihedi, Force (Vital Force), Missing Link, Muntu, Ntu, Nkedi, Ubuntu, Uwa Introduction African philosophy is a critical and rational explanation of being in African context, and based on African logic. It is in line with this that Jonathan Chimakonam avers that “in African philosophy we study reality of which being is at the center” (2013, 73). William Wallace remarks that “being signifies a concept that has the widest extension and the least comprehension” (1977, 86). It has posed a lot of problems to philosophers who tend to probe into it, its nature and manifestations.

First of all I would like to thank my supervisor and promotor Lodi Nauta for his comments on an enormous variety of drafts and for the many stimulating discussions we had throughout the project. He did not limit himself to deeply theoretical discussions but also saved me from grammatical and stylish sloppiness. (He would, for example, have suggested to leave out the ‘enormous’ and ‘many’ above, as well as by far most of the ‘very’’s and ‘greatly’’s in the sentences to come.) After I had already started my new job outside the academic world, Lodi regularly – but always in a pleasant way – reminded me of this other job that still had to be finished.

  • Metaphysics and Natural Kinds: Slingshots, Fundamentality, and Causal Structure
    METAPHYSICS AND NATURAL KINDS: SLINGSHOTS, FUNDAMENTALITY, AND CAUSAL STRUCTURE By ANDREW LEE MCFARLAND Submitted to the graduate degree program in the Department of Philosophy and the Graduate Faculty of the University of Kansas in partial fulfillment of the requirements for the degree of Doctor of Philosophy. ________________________________ Chair: John Symons ________________________________ John Bricke ________________________________ Armin Schulz ________________________________ Clif Pye ________________________________ Philippe Huneman Date Defended: May 16, 2014 The Dissertation Committee for Andrew Lee McFarland certifies that this is the approved version of the following dissertation: METAPHYSICS AND NATURAL KINDS: SLINGSHOTS, FUNDAMENTALITY, AND CAUSAL STRUCTURE ________________________________ JOHN SYMONS Date approved: May 16, 2014 ii DISSERTATION ABSTRACT Metaphysics and Natural Kinds: Slingshots, Fundamentality, and Causal Structure Andrew Lee McFarland My dissertation addresses a question relevant to metaphysics, philosophy of language, and philosophy of science: What are natural kinds? I explore a view that holds that natural kinds are complex, structural properties that involve causal structure. Causal structure describes the idea that for the many properties associated with natural kinds, these properties are nomically linked – that is causally connected – in such a way that the properties of non-natural kinds are not. After criticizing arguments in favor of a nominalist theory of kinds – one that holds that a natural kind just is to be identified with its class of instances – and after defending the notion of a complex structural property from several prominent objections posed by David Lewis, I apply a causal account of natural kinds to a set of problematic cases, paying special attention to isomeric kinds from chemistry. iii Dedication I dedicate this doctoral thesis to my family and to the tireless support they have given me over the years.

  • Ontological Pluralism About Non-Being Sara Bernstein, University of Notre Dame
    Ontological Pluralism about Non-Being Sara Bernstein, University of Notre Dame Forthcoming in Non-Being: New Essays on the Metaphysics of Nonexistence, eds. Bernstein and Goldschmidt, Oxford University Press (UK) Neither square circles nor manned lunar stations exist. But might they fail to exist in different ways? A common assumption is “no”: everything that fails to exist, fails to exist in exactly the same way. Non-being doesn’t have joints or structure, the thinking goes—it is just a vast, undifferentiated nothingness. Even proponents of ontological pluralism, the view that there are multiple ways of being, do not entertain the possibility of multiple ways of non-being. This paper is dedicated to the latter idea. I argue that ontological pluralism about non-being, roughly, the view that there are multiple ways of non-being, is both more plausible and defensible and than it first seems, and it has many useful applications across a wide variety of metaphysical and explanatory problems.1 Here is the plan. In section 1, I lay out ontological pluralism about non-being in detail, drawing on principles of ontological pluralism about being. I address whether and how the two pluralisms interact: some pluralists about non-being are monists about being, and vice-versa. I discuss logical quantification strategies for pluralists about non-being. In Section 2, I examine precedent for pluralism about non-being in the history of philosophy. In section 3, I discuss several applications of pluralism about non-being. I suggest that the view has explanatory power across a variety of domains, and that the the view can account for differences between nonexistent past and future times, between omissions and absences, and between different kinds of fictional objects.

  • Newton As Philosopher
    This page intentionally left blank NEWTON AS PHILOSOPHER Newton’s philosophical views are unique and uniquely difficult to categorize. In the course of a long career from the early 1670s until his death in 1727, he articulated profound responses to Cartesian natural philosophy and to the prevailing mechanical philosophy of his day. Newton as Philosopher presents Newton as an original and sophisti- cated contributor to natural philosophy, one who engaged with the principal ideas of his most important predecessor, René Descartes, and of his most influential critic, G. W. Leibniz. Unlike Descartes and Leibniz, Newton was systematic and philosophical without presenting a philosophical system, but, over the course of his life, he developed a novel picture of nature, our place within it, and its relation to the creator. This rich treatment of his philosophical ideas, the first in English for thirty years, will be of wide interest to historians of philosophy, science, and ideas.

To the best of my knowledge and belief, it contains no material previously published or written by another person, except where it is explicitly acknowledged in the text. No part of this thesis has been submitted for a degree at any other university or institution. Javier Belastegui Lazcano 1 Para Ane, que se sabe todas mis canciones. Abstract The aim of this thesis is to better understand the ways natural kinds are re- lated to each other by species-genus relations and the ways in which the members of the kind are related to each other by resemblance relations, by making use of formal models of kinds. This is done by first analysing a Minimal Conception of Natural Kinds and then reconstructing it from the ontological assumptions of Resemblance Nominalism. The questions addressed are: 1. What is the external structure of kinds? In what ways are kinds related to each other by species-genus relations? 2. What is the internal structure of kinds? In what sense are the instances of a kind similar enough to each other? According to the Minimal Conception of Natural Kinds, kinds have two components, a set of members of the kind (the extension) and a set of natural attributes common to these objects (the intension).

  • Kant on Nothing
    Nothing: Kant’s analysis and the Hegelian critique Tolga Güngör A thesis submitted for the degree of Ph.D. Department of Philosophy & Art History University of Essex February 2017 ABSTRACT This thesis aims to throw an illuminating light on the as yet neglected concept of nothing in Kant’s system, a concept which is taken into consideration, by Kant, in accordance with the guiding thread of the categories of the understanding. My main argument is that Kant has a fourfold division of nothing and each has a transcendental function in his system. This function is basically a limiting one; setting up negative determinations without which Kant’s system would have never been constituted as it is now. It is shown in the thesis that the concept of nothing is divided basically into four: first, nothing as ens rationis that limits and thereby protects knowledge, secondly nothing as nihil privativum that defines the boundaries of phenomenal reality, thirdly nothing as ens imaginarium that makes possible the unity of experience and finally, nothing as nihil negativum that draws the lines of logical thinking. All make, in the last resort and by being the concepts of the opposite, experience possible. The thesis consists of four chapters. The first chapter is an exposition of all four divisions of nothing, the second is the display specifically of the concepts of ens rationis and nihil negativum, and the third is of the concepts of ens imaginarium and nihil privativum. The auxiliary argument of the thesis is that while Hegel makes a strong charge of externality against and thereby severely criticizes the Kantian concept of the thing-in-itself, - the concept of which I propose to be contained under the concept of ens rationis- Kant has equally convincing arguments against such a charge.
