On the Boundary Between Mereology and Topology
On the Boundary Between Mereology and Topology Achille C. Varzi Istituto per la Ricerca Scientifica e Tecnologica, I-38100 Trento, Italy [email protected] (Final version published in Roberto Casati, Barry Smith, and Graham White (eds.), Philosophy and the Cognitive Sciences. Proceedings of the 16th International Wittgenstein Symposium, Vienna, Hölder-Pichler-Tempsky, 1994, pp. 423–442.) 1. Introduction Much recent work aimed at providing a formal ontology for the common-sense world has emphasized the need for a mereological account to be supplemented with topological concepts and principles. There are at least two reasons under- lying this view. The first is truly metaphysical and relates to the task of charac- terizing individual integrity or organic unity: since the notion of connectedness runs afoul of plain mereology, a theory of parts and wholes really needs to in- corporate a topological machinery of some sort. The second reason has been stressed mainly in connection with applications to certain areas of artificial in- telligence, most notably naive physics and qualitative reasoning about space and time: here mereology proves useful to account for certain basic relation- ships among things or events; but one needs topology to account for the fact that, say, two events can be continuous with each other, or that something can be inside, outside, abutting, or surrounding something else. These motivations (at times combined with others, e.g., semantic transpar- ency or computational efficiency) have led to the development of theories in which both mereological and topological notions play a pivotal role. How ex- actly these notions are related, however, and how the underlying principles should interact with one another, is still a rather unexplored issue. -

Metaphysics Today and Tomorrow*
1 Metaphysics Today and Tomorrow* Raphaël Millière École normale supérieure, Paris – October 2011 Translated by Mark Ohm with the assistance of Leah Orth, Jon Cogburn, and Emily Beck Cogburn “By metaphysics, I do not mean those abstract considerations of certain imaginary properties, the principal use of which is to furnish the wherewithal for endless dispute to those who want to dispute. By this science I mean the general truths which can serve as principles for the particular sciences.” Malebranche Dialogues on Metaphysics and Religion 1. The interminable agony of metaphysics Throughout the twentieth century, numerous philosophers sounded the death knell of metaphysics. Ludwig Wittgenstein, Rudolf Carnap, Martin Heidegger, Gilbert Ryle, J. L. Austin, Jacques Derrida, Jürgen Habermas, Richard Rorty, and, henceforth, Hilary Putnam: a great many tutelary figures have extolled the rejection, the exceeding, the elimination, or the deconstruction of first philosophy. All these necrological chronicles do not have the same radiance, the same seriousness, nor the same motivations, but they all agree to dismiss the discipline, which in the past was considered “the queen of the sciences”, with a violence at times comparable to the prestige it commanded at the time of its impunity. Even today, certain philosophers hastily spread the tragic news with contempt for philosophical inquiry, as if its grave solemnity bestowed upon it some obviousness. Thus, Franco Volpi writes: ‘Grand metaphysics is dead!’ is the slogan which applies to the majority of contemporary philosophers, whether continentals or of analytic profession. They all treat metaphysics as a dead dog.1 In this way, the “path of modern thought” would declare itself vociferously “anti- metaphysical and finally post-metaphysical”. -

Velikov* Department of Finance and Management, Plovdiv University "Paisii Hilendarski", Plovdiv, Bulgaria ABSTRACT The amortization charge leads to an improvement in the quality of accountability and public finance statistics. Accounting analysis is part of the information function of accounting. The aim of the publication is to analyze depreciation in municipalities and to propose a synthesis of properties and a summary of common features, trends and laws. The ontological nature of depreciation in accounting science presents the main problems solved by accounting for depreciation. Epistemological coverage of depreciation covers its origin, scope and peculiarities. The research methods are analysis and synthesis, comparison, analogy, modeling, systematization and summary, comparative and group accounting analysis. The results obtained are presented in tabular form. The conclusion is that by switching from a smaller range of the signage coverage of the unit to the depreciation in municipalities, we are targeting a wider range of sign coverage, pointing out the qualities of the different categories of depreciation in the municipalities as an internal definition and an external manifestation. Key words: depreciation, theoretical analysis, accounting, public sector, category, quality. INTRODUCTION expression of the systematic distribution of the The accrual of depreciation in the public sector depreciable value of the asset over its last life. leads to an improvement in the quality of The subject of the survey is the normative accountability and public finance statistics. -
The Logic of Discrete Qualitative Relations
The Logic of Discrete Qualitative Relations Giulia Sindoni1 and John G. Stell2 1 School of Computing, University of Leeds, Leeds, UK [email protected] 2 School of Computing, University of Leeds, Leeds, UK [email protected] Abstract We consider a modal logic based on mathematical morphology which allows the expression of mereotopological relations between subgraphs. A specific form of topological closure between graphs is expressible in this logic, both as a combination of the negation ¬ and its dual ¬, and as modality, using the stable relation Q, which describes the incidence structure of the graph. This allows to define qualitative spatial relations between discrete regions, and to compare them with earlier works in mereotopology, both in the discrete and in the continuous space. 1998 ACM Subject Classification I.2.4 Knowledge Representation Formalisms and Methods Keywords and phrases Modal logic, Qualitative spatial reasoning, Discrete space Digital Object Identifier 10.4230/LIPIcs.COSIT.2017.1 1 Introduction Qualitative spatial relations have a long history with two major strands: the Region- Connection Calculus (RCC) of Randell et al. [10] and the 9-intersection approach of Egenhofer et al. [5]. These were initially intended to model ‘continuous’, or more precisely ‘dense’, space that can be subdivided indefinitely often. The RCC is defined in terms of first order axioms based on a primitive predicate of connection. The intersection-based theories, on the other hand, evaluate spatial scenarios through a matrix of statements that pairs of features of two regions have non-empty intersection. In the 9-intersection case a pair of regions A, B is given a spatial relationship by considering the interior, boundary, and exterior of each region and obtaining a matrix of truth values from the emptiness or non-emptiness of the 9 possible intersections between the three features of A and of B. -

Parts, Wholes, and Part-Whole Relations: the Prospects of Mereotopology
PARTS, WHOLES, AND PART-WHOLE RELATIONS: THE PROSPECTS OF MEREOTOPOLOGY Achille C. Varzi Department of Philosophy, Columbia University (New York) (Published in Data and Knowledge Engineering 20 (1996), 259–286.) 1. INTRODUCTION This is a brief overview of formal theories concerned with the study of the notions of (and the relations between) parts and wholes. The guiding idea is that we can dis- tinguish between a theory of parthood (mereology) and a theory of wholeness (holology, which is essentially afforded by topology), and the main question exam- ined is how these two theories can be combined to obtain a unified theory of parts and wholes. We examine various non-equivalent ways of pursuing this task, mainly with reference to its relevance to spatio-temporal reasoning. In particular, three main strategies are compared: (i) mereology and topology as two independent (though mutually related) theories; (ii) mereology as a general theory subsuming topology; (iii) topology as a general theory subsuming mereology. This is done in Sections 4 through 6. We also consider some more speculative strategies and directions for further research. First, however, we begin with some preliminary outline of mereol- ogy (Section 2) and of its natural bond with topology (Section 3). 2. MEREOLOGY: A REVIEW The analysis of parthood relations (mereology, from the Greek meroV, ‘part’) has for a long time been a major focus of philosophical investigation, beginning as early as with atomists and continuing throughout the writings of ancient and medieval ontologists. It made its way into contemporary philosophy through the work of Brentano and of his pupils, most notably Husserl’s third Logical Investigation, and it has been subjected to formal treatment from the very first decades of this century. -

Vector Calculus MA3VC 2016-17
Vector calculus MA3VC 2016–17: Assignment 1 SOLUTIONS AND FEEDBACK (Exercise 1) Prove that if f is a (smooth) scalar field and G~ is an irrotational vector field, then (∇~ f × G~ )f is solenoidal. Hint: do not expand in coordinates and partial derivatives. Use instead the vector differential identities of §1.4 and the properties of the vector product from §1.1.2 (recall in particular Exercise 1.15). (Version 1) We compute the divergence of the vector field (∇~ f × G~ )f using the product rules (29) and (30) for the divergence: (29) ∇~ · (∇~ f × G~ )f = ∇~ f · (∇~ f × G~ )+ f∇~ · (∇~ f × G~ ) (30) = ∇~ f · (∇~ f × G~ )+ f(∇×~ ∇~ f) · G~ − f∇~ f · (∇×~ G~ ). The first term in this expression vanishes1 because of the identities u~ ·(~u×w~ )= w~ ·(~u×~u) (by Exercise 1.15) and ~u × u~ = ~0 (by the anticommutativity of the vector product (3)), which hold for all u~ , w~ ∈ R3. Applying these formulas with ~u = ∇~ f and w~ = G~ we get ∇~ f · (∇~ f × G~ )= G~ · (∇~ f × ∇~ f)= G~ · ~0 = 0. The second term vanishes because of the “curl-grad identity” (26): ∇×~ ∇~ f = ~0. The last term vanishes because G~ is irrotational: ∇×~ G~ = ~0. So we conclude that the field (∇~ f × G~ )f is solenoidal because its divergence vanishes: ∇~ · (∇~ f × G~ )f = G~ · (∇~ f × ∇~ f)+ f(∇×~ ∇~ f) · G~ − f∇~ f · (∇×~ G~ )=0. =~0 =~0 =~0 | {z } | {z } | {z } (Version 2) Alternatively, one could expand the field in coordinates. This solution is of course much more complicated and prone to errors than the previous one. We first write the product rule for products of three scalar fields, which is proved by applying twice the usual product rule for partial derivatives (8): ∂ ∂ (8) ∂(fg) ∂h (8) ∂f ∂g ∂h ∂f ∂g ∂h (fgh)= (fg)h = h + fg = g + f h + fg = gh + f h + fg . -
On the Phases of Reism §1. Introduction
On the Phases of Reism1 BARRY SMITH §1. Introduction Along with almost all the more important Polish philosophers of the twentieth century, Kotarbiński, too, was a student of Kasimir Twardowski, and it is Twardowski who is more than anyone else responsible for the rigorous thinking and simplicity of expression that is so characteristic of Kotarbiński’s work. Twardowski was of course himself a member of the Brentanist movement, and the influence of Brentanism on Kotarbiński’s writings reveals itself clearly in the fact that the ontological theories which Kotarbiński felt called upon to attack in his writings were in many cases just those theories defended either by Twardowski or by other thinkers within the Brentano tradition. Leśniewski, too, inherited through Twardowski an interest in Brentano and his school, and as a young man he had conceived the project of translating into Polish the Investigations on General Grammar and Philosophy of Language of Anton Marty, one of Brentano’s most intimate disciples. Leśniewski, as he himself expressed it, grew up “tuned to general grammar and logico-semantic problems à la Edmund Husserl and the representatives of the so-called Austrian School”. (1927/31, p. 9) The influence of Brentanism on Polish analytic philosophers such as Kotarbiński and Leśniewski has, however, been largely overlooked– principally as a result of the fact that the writings of the Polish analytic school have been perceived almost exclusively against the background of Viennese positivism or of Anglo-Saxon analytic philosophy. It is hoped that the present paper, following in the footsteps of Jan Woleński’s recent work,2 might do something to help rectify this imbalance.
