From Locke to Berkeley
From Locke to Berkeley How Berkeley rejects Locke’s Metaphysical Realism in favor of what he calls “Idealism” Locke Summary Like Descartes, Locke believes that we perceive the “real” world only indirectly. • We do not directly perceive material objects, – Just as we do not directly perceive people we see on T.V.; • Rather, we directly perceive only ideas (sensations, things “in” our minds) that are caused by and represent material objects, – Just as, when watching T.V., we directly see only images on the screen. Locke’s Causal Theory of Perception: Indirectly Sensation aware of Matter Do our sensations resemble their objects? • Recall that Descartes’ big worry was whether or not there were any objects outside our minds. – (By the end of the 6th Meditation, he assures that there are.) • But he said we also make mistakes in thinking that our ideas always resembled the objects in the real world that caused us to have those sensations. Why should we believe that the ideas in our minds actually resemble the objects outside our minds that cause them? Mind’s Eye Idea Object Idea Object Mind In Locke’s Terms • Even if we accept that the ideas in our mind are caused by real objects that exist outside our minds – (Locke never really questions this) • Is it true that our ideas always resemble the qualities in the objects that caused us to have those ideas? Locke’s Answer • Only sometimes. Some of our ideas do resemble qualities in the objects, but some of them do not. • Our ideas of primary qualities resemble those qualities. -
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. -
The Joint Philosophical Program of Russell and Wittgenstein and Its Demise
The Joint Philosophical Program of Russell and Wittgenstein and Its Demise Abstract Between April and November 1912, Bertrand Russell and Ludwig Wittgenstein were en- gaged in a joint philosophical program. Wittgenstein‘s meeting with Gottlob Frege in De- cember 1912 led, however, to its dissolution – the joint program was abandoned. Section 2 of this paper outlines the key points of that program, identifying what Russell and Wittgenstein each contributed to it. The third section determines precisely those features of their collabora- tive work that Frege criticized. Finally, building upon the evidence developed in the preced- ing two sections, section 4 recasts along previously undeveloped lines Wittgenstein‘s logical– philosophical discoveries in the two years following his encounter with Frege in 1912. The paper concludes, in section 5, with an overview of the dramatic consequences the Frege- Wittgenstein critique had for Russell‘s philosophical development. 1. Introductory Remarks The subject of our investigation is the interaction between the three founding fathers of analytic philosophy, Russell, Wittgenstein and Frege, in a most important period of their philosophical development. We discuss the joint program that Russell and Wittgenstein worked on from April till November 1912, as well as its collapse after Wittgenstein visited Frege in Jena in December the same year. Frege‘s criticism of elements of the program underpinned and motivated Wittgenstein‘s attack on Russell‘s approach in philosophy that culminated in May and June 1913 when, facing Wittgenstein‘s criticism, Russell stopped writing the Theory of Knowledge book project. Frege‘s arguments also urged Wittgenstein to rethink and reformulate his own philosophical ideas. -
Descartes' Arguments for Distinguishing Mind and Body
© Michael Lacewing Descartes’ arguments for distinguishing mind and body THE KNOWLEDGE ARGUMENT In Meditation II, having argued that he knows he thinks, Descartes then asks what kind of thing he is. Discussions of identity seek to establish the essential properties of something, what makes it the thing that it is. The question ‘what am I?’ can be answered by considering the question of what it is for me to exist. Descartes is trying to identify his essence, those properties which, if he lost them, would mean he was no longer what he is. (An island, for instance, must be surrounded by water. If the water dried up, joining it to the mainland, it would cease to be an island.) He remarks that he can continue to doubt whether he has a body; after all, he only believes he has a body as a result of his perceptual experiences, and so the demon could be deceiving him about this. But he cannot doubt that he has a mind, i.e. that he thinks. So he knows he exists even though he doesn’t know whether or not he has a body. From this Descartes concludes that it is possible for him to exist without a body. He is essentially a mind, not a body. He would not necessarily cease to be himself if he ceased to have a body, but he would necessarily cease to be himself if he didn’t have a mind. APPEAL TO GOD’S OMNIPOTENCE Descartes’ argument so far is that minds can exist without bodies. However, on its own, it doesn’t establish dualism. -
Transparency of Mind: the Contributions of Descartes, Leibniz, and Berkeley to the Genesis of the Modern Subject
Transparency of Mind: The Contributions of Descartes, Leibniz, and Berkeley to the Genesis of the Modern Subject Gary Hat! eld Philosophers often use classical positions as paradigms for de! ning their own views, usually in contrast. In the philosophy of mind, the notion of the Cartesian subject is one such paradigm. This notion is often used to represent tendencies in the conception of the subject that today’s philosophers wish to avoid. John McDowell and Hilary Putnam 1, among others, portray the Cartesian subject – and speci! cally the Cartesian mind – as a step backward from an earlier, preferable Aristotelianism, whose concept of mind might be made serviceable today if adjusted to ! t modern science. Such paradigms, whose use is unavoidable, are typically caricatures, whether slight or gross. The Cartesian mind as standardly portrayed by McDowell, Putnam, and oth- ers 2 is a gross caricature. This would be important enough for its potential to mislead us about the actual historical development of philosophy. But even more crucially for the philosophy of mind, the use of a caricatured picture as a counterparadigm against which one de! nes one’s own, comparatively better position, can lead to a pyrrhic vic- tory that avoids or misrepresents the real problems. If the opponent has been tailored to one’s desired virtues as conquering hero, one may give the impression that one’s own position solves great problems, deeply embedded in the tradition, when in fact one has simply rejected a fairly recent problematic position, which one has perhaps also misun- derstood and misidenti! ed. 3 The Cartesian mental paradigm is frequently de! ned in terms of four factors: con- sciousness as essence, intentionality as exclusively mental, the veil of perception, and the transparency of mind. -
Abstract 1. Russell As a Mereologist
THE 1900 TURN IN BERTRAND RUSSELL’S LOGIC, THE EMERGENCE OF HIS PARADOX, AND THE WAY OUT Prof. Dr. Nikolay Milkov, Universität Paderborn, [email protected] Abstract Russell‘s initial project in philosophy (1898) was to make mathematics rigorous reducing it to logic. Before August 1900, however, Russell‘s logic was nothing but mereology. First, his acquaintance with Peano‘s ideas in August 1900 led him to discard the part-whole logic and accept a kind of intensional predicate logic instead. Among other things, the predicate logic helped Russell embrace a technique of treating the paradox of infinite numbers with the help of a singular concept, which he called ‗denoting phrase‘. Unfortunately, a new paradox emerged soon: that of classes. The main contention of this paper is that Russell‘s new con- ception only transferred the paradox of infinity from the realm of infinite numbers to that of class-inclusion. Russell‘s long-elaborated solution to his paradox developed between 1905 and 1908 was nothing but to set aside of some of the ideas he adopted with his turn of August 1900: (i) With the Theory of Descriptions, he reintroduced the complexes we are acquainted with in logic. In this way, he partly restored the pre-August 1900 mereology of complexes and sim- ples. (ii) The elimination of classes, with the help of the ‗substitutional theory‘,1 and of prop- ositions, by means of the Multiple Relation Theory of Judgment,2 completed this process. 1. Russell as a Mereologist In 1898, Russell abandoned his short period of adherence to the Neo-Hegelian position in the philosophy of mathematics and replaced it with what can be called the ‗analytic philoso- phy of mathematics‘, substantiated by the logic of relations. -

Plurals and Mereology
Journal of Philosophical Logic (2021) 50:415–445 https://doi.org/10.1007/s10992-020-09570-9 Plurals and Mereology Salvatore Florio1 · David Nicolas2 Received: 2 August 2019 / Accepted: 5 August 2020 / Published online: 26 October 2020 © The Author(s) 2020 Abstract In linguistics, the dominant approach to the semantics of plurals appeals to mere- ology. However, this approach has received strong criticisms from philosophical logicians who subscribe to an alternative framework based on plural logic. In the first part of the article, we offer a precise characterization of the mereological approach and the semantic background in which the debate can be meaningfully reconstructed. In the second part, we deal with the criticisms and assess their logical, linguistic, and philosophical significance. We identify four main objections and show how each can be addressed. Finally, we compare the strengths and shortcomings of the mereologi- cal approach and plural logic. Our conclusion is that the former remains a viable and well-motivated framework for the analysis of plurals.

Introduction to the Philosophy of Cognitive Science by Dr
Introduction to the Philosophy of Cognitive Science By Dr. Charles Wallis Last revision: 1/23/2013 Chapter 2 Greek Metaphysical Speculation: Philosophical Materialisms and Dualisms 2.1 Introduction It may seem odd to the contemporary thinker to suppose that people did not always have a clear conception of the mind and of mental phenomena. Nevertheless, like most contemporary western concepts the development of the notion of the mind and of mental phenomena actually occurs over the course of centuries. Indeed, the development of the notion of “the mind” arguably traces back to the development of the Greek notion of the soul. For most of Greek history the conception of the soul bears little resemblance to its contemporary western counterpart. In fact, the Greeks develop their notion of the soul as part of the development of general ontological frameworks for scientific and metaphysical speculation. Three features of the development of the Greek notion of the soul figure prominently in this rather superficial history. First, the development of the Greek notion of the soul represents a slow accretion of properties and processes associated with three different contemporary distinctions into a single ontological entity; living vs non-living, animate vs inanimate, and mental vs non-mental. Second, as the soul becomes more distinct both in its nature and in its functions, the Greeks begin to more actively debate whether the soul constitutes a fundamental kind of stuff (a distinct substance) or merely one of many permutations of more fundamental kinds of stuff (substances). For instance, early Greek thinkers often supposed that the universe consists of various permutations of one or more fundamental elements. -

For UCLA Workshop. Please Don’t Cite Or Quote Without Permission. Norm and Object: A Normative Hylomorphic Theory of Social Objects Asya Passinsky ABSTRACT: This paper is an investigation into the metaphysics of social objects such as political borders, states, and organizations. I articulate a metaphysical puzzle concerning such objects and then propose a novel account of social objects that provides a solution to the puzzle. The basic idea behind the puzzle is that under appropriate circumstances, seemingly concrete social objects can apparently be created by acts of agreement, decree, declaration, or the like. Yet there is reason to believe that no concrete object can be created in this way. The central idea of my positive account is that social objects have a normative component to them, and seemingly concrete social objects have both normative and material components. I develop this idea more rigorously using resources from the Aristotelian hylomorphic tradition. The resulting normative hylomorphic account, I argue, solves the puzzle by providing a satisfying explanation of creation-by-agreement and the like, while at the same time avoiding the difficulties facing extant accounts of social objects. 1. Introduction This paper is an investigation into the metaphysics of social objects such as political borders, states, and organizations. Roughly speaking, social objects are things that can be created through the performance of social acts such as agreement, decree, declaration, or the like. -
Mereology Then and Now
Logic and Logical Philosophy Volume 24 (2015), 409–427 DOI: 10.12775/LLP.2015.024 Rafał Gruszczyński Achille C. Varzi MEREOLOGY THEN AND NOW Abstract. This paper offers a critical reconstruction of the motivations that led to the development of mereology as we know it today, along with a brief description of some questions that define current research in the field. Keywords: mereology; parthood; formal ontology; foundations of mathe- matics 1. Introduction Understood as a general theory of parts and wholes, mereology has a long history that can be traced back to the early days of philosophy. As a formal theory of the part-whole relation or rather, as a theory of the relations of part to whole and of part to part within a whole it is relatively recent and came to us mainly through the writings of Edmund Husserl and Stanisław Leśniewski. The former were part of a larger project aimed at the development of a general framework for formal ontology; the latter were inspired by a desire to provide a nominalistically acceptable alternative to set theory as a foundation for mathematics. (The name itself, ‘mereology’ after the Greek word ‘µρoς’, ‘part’ was coined by Leśniewski [31].) As it turns out, both sorts of motivation failed to quite live up to expectations. Yet mereology survived as a theory in its own right and continued to flourish, often in unexpected ways. Indeed, it is not an exaggeration to say that today mereology is a central and powerful area of research in philosophy and philosophical logic. It may be helpful, therefore, to take stock and reconsider its origins.
