One such reason is that ‘exists’ cannot be predicated of individuals, and another is that first-level properties are parasitic on individuals for their actuality, which is something that existence could never be. A third is that, unlike all other real properties, existence would not add anything to an individual. Moreover, even if, per impossibile, existence were to survive all three counter-indications, it would be nothing but the most vacuous of properties. These claims, however, are testimony to what happens when wrong questions are asked, when false assumptions are made, and when the possibility of a new paradigm for existence is not so much as entertained. In other words, they testify to the substantial flaws underlying the familiar claim ‘Existence is not a predicate’ and the Frege-Russell-Quine view not only of ‘exists’ as exclusively a second- level predicate but of existence as no more than a Cambridge prop- erty of individuals. By way of contrast, the account in the following pages is a story of what happens when different questions are asked, when false as- sumptions are eschewed, and when the possibility of a radically dif- ferent paradigm for existence is actively explored rather than completely ignored. It is a story that underlies acceptance of ‘exists’ as predicable of individuals, and of existence as the richest of an in- dividual’s properties, albeit far from invariant from individual to in- dividual. Finally, it is a story that culminates in showing how perfectly good sense can be made of the notion ‘the fullness of being.’ ix © 2012 University of Notre Dame x Preface The book is dedicated to the late Christopher Williams, a friend who would have appreciated my gesture even if not my views. It be- longs to what might loosely be called a ‘trilogy’, the other members of which are From Existence to God (1992) and A Most Unlikely God (1996). Characteristic of each is their selective drawing on some of the insights from Frege and Aquinas. It is with deep gratitude that I acknowledge my debt not only to the comments of David Burrell and Brian Davies, but especially to detailed discussions with Peter Forrest, Mike Loux, and William Vallicella.

Although the verb ‘exists’ is as easy to use as the two-times table, it is no small feat to say just what it means for a con- crete individual to exist.1 Existing seems to be at least as mundane as walking or being hungry. Yet, when we say ‘Tom is hungry’ or ‘Tom is walking,’ it may be news to those not in Tom’s vicinity, whereas ‘Tom exists’ would be news to no one who knew of Tom as a healthy human being, and merely puzzling to those who had never heard of him. Again,we can readily indicate what is meant by Tom’s walk- ing, but surely Tom’s existence is not something we can indicate to anyone. On the face of it, we are greatly challenged to explain just what his existence is or what ‘existence’ means. If we hearken to the voices of Russell and the late Christopher Williams, it is a challenge that we ignore at our peril, for Russell counsels that ‘an almost unbelievable amount of false philosophy has arisen through not realizing what “existence” means.’2 Presum- ably, his targets include such diverse philosophies as those of Parmenides, Plato, Aristotle, Aquinas, Heidegger, Paul Weiss, and 1. A concrete object can either cause or undergo change. An abstract object can do neither. 2. B. Russell, Logic and Knowledge, R. C. Marsh, ed. (London: Allen and Unwin, 1955), 234. 1 © 2012 University of Notre Dame 2 the fullness of being Milton Munitz,3 to mention but a few, all of which fall in varying ways under the umbrella phrase ‘philosophies of Being or Existence.’ Williams dismisses them as ‘paradigms of what Wittgenstein called man’s bewitchment by language,’ a bewitchment said to underlie the belief that ‘the idea of existence is something deep and important, that existence is the central topic of philosophy.’4 His distinguished work What Is Existence? seeks to exorcize those who have been thus bewitched. In it he offers readers an uncompromising apologia for the Frege-Russell view of existence, and in particular its twin claims that existence is not a property of individuals and that the expres- sion ‘exists’ is not predicable of them. In so doing, his avowed aim is ‘to destroy the foundations of an enormous amount of meta- physics.’5 Unconvinced by the Fregean thesis promoted by such as Russell, Quine, and Williams, I shall be arguing that the case for ‘exists’ being predicable of concrete objects is a product not of any bewitchment by language but of a distinctly more careful attention to language than Fregeans have been wont to give it. Before embarking on that task, however, it might be illuminating to reflect briefly not only on Frege’s remarks on the existential use of ‘exists’ and ‘is,’ but on con- tributions from other sources as well. I. Frege In presenting Frege’s views, I should mention that the existential use of ‘is’ is merely one of the four uses that he distinguished. Although 3. M.

Williams, What Is Existence? (Oxford: Oxford University Press, 1981), ix. In similar vein, Simon Blackburn has suggested that ‘a cen- tral mistake in this area is to treat Being as a particularly deep subject mat- ter.’ He has then given voice to the arresting, though unoriginal, view that ‘this is parallel to treating Nothing as a name for a particular thing. .’ Dic- tionary of Philosophy (Oxford: Oxford University Press, 1994), 4. 5. Ibid. © 2012 University of Notre Dame The Question about ‘Exists’ and Existence 3 multiplicity of uses may or may not reflect any multiplicity of senses rather than merely differences of force, Frege had reasons for think- ing that the four senses were not even systematically ambiguous or analogical, but had nothing at all in common. Each of the senses was borne by one or other of the four uses—by the ‘is’ of predication, of existence, of generic implication (class inclusion), and of identity, as illustrated below. • The ‘is’ of predication, e.g., ‘Socrates is wise,’ rendered as ‘Wise (Socrates)’. • The existential ‘is’, e.g., ‘Socrates is’ and ‘There are crocodiles,’ the former being rendered in canonical language as ‘(∃x)(x = Socrates)’, and the latter as ‘(∃x)(x is a crocodile).’ • The ‘is’ of generic implication, e.g., ‘A crocodile is a reptile’, ren- dered as ‘(x)(crocodile(x) ⊃reptile(x)).’ • The ‘is’ of identity, e.g., ‘Cicero is Tully,’ rendered as ‘Cicero = Tully.’ Although Frege clearly distinguishes the four uses, in no place does he group them all together. In one part the ‘is’ of (first-level) predication is distinguished from that of class inclusion, in another the ‘is’ of identity is distinguished from that of (first-level) predica- tion, and in another the ‘is’ of existence is distinguished from that of (first-level) predication.6 Fundamental to the distinctions are some of the now familiar Fregean doctrines concerning sense and refer- ence, objects and concepts, and different levels of concepts, all being distinctions that I shall be employing in subsequent chapters. Objects are the referents of proper names which, for Frege, include all sin- gular referring expressions; and concepts are the referents of predi- cates (concept expressions). According to Frege, a concept is not an intentional entity, as the term might have suggested. Rather, it is a property and is no less an ontological item than is an object, the 6. Predicates are first-level if they are said of individuals. They are second-level if they are said of properties of individuals. © 2012 University of Notre Dame 4 the fullness of being difference being that properties (concepts) are incomplete entities whereas objects are complete.7 In an atomic proposition like ‘Socrates is wise’ the name ‘Soc- rates’ is to be distinguished from what is attached to it, namely, a predicate or concept expression. The name refers to an object and the predicate to a concept. A predicate that is said of an object is a first-level one.

  • Gottlob Frege Patricia A
    Gottlob Frege Patricia A. Blanchette This is the penultimate version of the essay whose final version appears in the Oxford Handbook of Nineteenth-Century German Philosophy, M. Forster and K. Gjesdal (eds), Oxford University Press 2015, pp 207-227 Abstract Gottlob Frege (1848-1925) made significant contributions to both pure mathematics and philosophy. His most important technical contribution, of both mathematical and philosophical significance, is the introduction of a formal system of quantified logic. His work of a more purely- philosophical kind includes the articulation and persuasive defense of anti-psychologism in mathematics and logic, the rigorous pursuit of the thesis that arithmetic is reducible to logic, and the introduction of the distinction between sense and reference in the philosophy of language. Frege’s work has gone on to influence contemporary work across a broad spectrum, including the philosophy of mathematics and logic, the philosophy of language, and the philosophy of mind. This essay describes the historical development of Frege’s central views, and the connections between those views. Introduction Friedrich Ludwig Gottlob Frege was born on November 8, 1848 in the Hanseatic town of Wismar. He was educated in mathematics at the University of Jena and at the University of Göttingen, from which latter he received his doctorate in 1873. He defended his Habilitation the next year in Jena, and took up a position immediately at the University of Jena. Here he spent his entire academic career, lecturing in mathematics and logic, retiring in 1918. His death came on July 26, 1925 in the nearby town of Bad Kleinen.1 Frege is best known for three significant contributions to philosophy.

  • Gottlob Frege: on Sense and Reference Professor Jeeloo Liu [Introduction]
    Phil/Ling 375: Meaning and Mind [Handout #13] Gottlob Frege: On Sense and Reference Professor JeeLoo Liu [Introduction] I. Language and the World ___ How does language depict reality? Does reality have the same structure as the structure of language? For instance, the basic linguistic structure is a subject and a predicate, and the basic structure of the world is a particular and a universal (e.g. “Socrates is wise”). The subject usually is something of the world and we describe some property it has or does not have. A is F is true is A is really F, is false when A is not F. II. Different Elements of Language Singular terms: Terms that designate particular things Proper names Indexicals: now, today, here, I… Demonstratives: that, this… Pronouns (singular): he, she,… Definite descriptions (the so-and-so): Indefinite (singular) descriptions (a so-and-so) General terms: Terms that designate a kind of things or a certain property Mass nouns ___ natural kind terms (‘water,’ ‘tiger,’ ‘lemon’) ___ non-natural kind terms (‘bachelor’, ‘contract,’ ‘chair’) Adjectives (predicates): colors, shapes, etc. III. Traditional Theories of Meaning Prior to Frege [A] The Ideational Theory ___ The meaning of a linguistic expression is the speaker’s idea that is associated with the expression. [B] Mill’s Theory [the Object Theory] ___ The meaning of a singular term is the thing designated by that term; ___ the meaning of a name is just what the name stands for; the name does not have any other meaning e.g. ‘Socrates’ means Socrates e.g. ‘Dartmouth’ e.g.

Plato is one of the great contributors to the foundations of mathematics. He discussed, 2400 years ago, the importance of clear and precise definitions as fundamental entities in mathematics, independent of the human mind. In the seventh book of his masterpiece, The Republic, Plato states “arithmetic has a very great and elevating effect, compelling the soul to reason about abstract number, and rebelling against the introduction of visible or tangible objects into the argument” (525c). In the light of this thought, I will discuss the status of mathematical entities in the twentieth first century, an era when it is already possible to demonstrate theorems and construct formal axiomatic derivations of remarkable complexity with artificial intelligent agents the modern theorem provers.

  • Frege's Influence on Wittgenstein: Reversing Metaphysics Via the Context Principle*
    Frege's Influence on Wittgenstein: Reversing Metaphysics via the Context Principle* Erich H. Reck Gottlob Frege and Ludwig Wittgenstein (the later Wittgenstein) are often seen as polar opposites with respect to their fundamental philosophical outlooks: Frege as a paradig- matic "realist", Wittgenstein as a paradigmatic "anti-realist". This opposition is supposed to find its clearest expression with respect to mathematics: Frege is seen as the "arch-pla- tonist", Wittgenstein as some sort of "radical anti-platonist". Furthermore, seeing them as such fits nicely with a widely shared view about their relation: the later Wittgenstein is supposed to have developed his ideas in direct opposition to Frege. The purpose of this paper is to challenge these standard assumptions. I will argue that Frege's and Wittgen- stein's basic outlooks have something crucial in common; and I will argue that this is the result of the positive influence Frege had on Wittgenstein. It would be absurd to claim that there are no important differences between Frege and Wittgenstein. Likewise, it would be absurd to claim that the later Wittgenstein was not critical of some of Frege's ideas. What, then, is the common element I see? My sugges- tion is that the two thinkers agree on what I call a reversal of metaphysics (relative to a standard kind of metaphysics attacked by both). This is not an agreement on one particu- lar thesis or on one argument. Rather, it has to do with what is prior and what is posterior when it comes to certain fundamental explanations in metaphysics (also, relatedly, in semantics and epistemology).

  • The History of Logic
    c Peter King & Stewart Shapiro, The Oxford Companion to Philosophy (OUP 1995), 496–500. THE HISTORY OF LOGIC Aristotle was the first thinker to devise a logical system. He drew upon the emphasis on universal definition found in Socrates, the use of reductio ad absurdum in Zeno of Elea, claims about propositional structure and nega- tion in Parmenides and Plato, and the body of argumentative techniques found in legal reasoning and geometrical proof. Yet the theory presented in Aristotle’s five treatises known as the Organon—the Categories, the De interpretatione, the Prior Analytics, the Posterior Analytics, and the Sophistical Refutations—goes far beyond any of these. Aristotle holds that a proposition is a complex involving two terms, a subject and a predicate, each of which is represented grammatically with a noun. The logical form of a proposition is determined by its quantity (uni- versal or particular) and by its quality (affirmative or negative). Aristotle investigates the relation between two propositions containing the same terms in his theories of opposition and conversion. The former describes relations of contradictoriness and contrariety, the latter equipollences and entailments. The analysis of logical form, opposition, and conversion are combined in syllogistic, Aristotle’s greatest invention in logic. A syllogism consists of three propositions. The first two, the premisses, share exactly one term, and they logically entail the third proposition, the conclusion, which contains the two non-shared terms of the premisses. The term common to the two premisses may occur as subject in one and predicate in the other (called the ‘first figure’), predicate in both (‘second figure’), or subject in both (‘third figure’).

  • 1 Introduction: Frege's Life and Work
    1 Introduction: Frege’s Life and Work Biography Friedrich Ludwig Gottlob Frege was the founder of modern math- ematical logic, which he created in his first book, Conceptual Nota- tion, a Formula Language of Pure Thought Modelled upon the Formula Language of Arithmetic (Begriffsschrift, eine der arithmetischen nachge- bildete Formalsprache des reinen Denkens (1879), translated in Frege 1972). This describes a system of symbolic logic which goes far beyond the two thousand year old Aristotelian logic on which, hitherto, there had been little decisive advance. Frege was also one of the main formative influences, together with Bertrand Russell, Ludwig Wittgenstein and G. E. Moore, on the analytical school of philosophy which now dominates the English-speaking philo- sophical world. Apart from his definitive contribution to logic, his writings on the philosophy of mathematics, philosophical logic and the theory of meaning are such that no philosopher working in any of these areas today could hope to make a contribution without a thorough familiarity with Frege’s philosophy. Yet in his lifetime the significance of Frege’s work was little acknowledged. Even his work on logic met with general incomprehension and his work in philosophy was mostly unread and unappreciated. He was, however, studied by Edmund Husserl, Bertrand Russell, Ludwig Wittgenstein and Rudolf Carnap and via these great figures he has eventually achieved general recognition. Frege’s life was not a personally fulfilled one (for more detailed accounts of the following see Bynum’s introduction to Frege 1972 2 Introduction: Frege’s Life and Work and Beaney’s introduction to Frege 1997).

  • Augustine's Mathematical Realism
    Augustine's Mathematical Realism Paul J. Zwier Calvin College Let me begin by giving a descriptive statement about what I take “Mathematical Realism” to be. Some philosophers of mathematics may identify the view as “mathematical Platonism.” I prefer the terminology “mathematical realism” as to avoid the prejudicial connotations which some might have regarding views held by Greek philosophers. Mathematical Realism is the view that certain mathematical statements are true because they successfully refer to entities which exist independently of the human mind and describe relationships which indeed, do exist between them. We, humans, can discover such true relationships between these entities. Some implications which are often drawn from this view are as follows: 1. In ontology and metaphysics: There are non-material objects. 2. In Philosophy of Mind and in Epistemology: The human mind has some kind of primitive intuition which accounts for the ability of humans to discover relationships between these non-material objects. I am sure that you are all aware of the fact that mathematical realism is not getting a very good “press” these days. It is true that those engaged in the practice of mathematics favor realism; at least psychologically. But many mathematicians retreat to formalism when they are asked to given an account of the nature of the objects under consideration in mathematics. But what is the case against mathematical realism? I shall summarize. The case has been given many times in the philosophical literature. An especially good example is the work of Philip Kitcher. He tries to show what tensions are involved in realism in a paper entitled The Plight of the Platonist which appeared in the journal Nous Volume 12, 1978, pages 119-134.

John Gordon MacFarlane, PhD University of Pittsburgh, 2000 Much philosophy of logic is shaped, explicitly or implicitly, by the thought that logic is distinctively formal and abstracts from material content. The distinction between formal and material does not appear to coincide with the more familiar contrasts between a pri- ori and empirical, necessary and contingent, analytic and synthetic—indeed, it is often invoked to explain these. Nor, it turns out, can it be explained by appeal to schematic inference patterns, syntactic rules, or grammar. What does it mean, then, to say that logic is distinctively formal? Three things: logic is said to be formal (or “topic-neutral”) (1) in the sense that it provides constitutive norms for thought as such, (2) in the sense that it is indifferent to the particular identities of objects, and (3) in the sense that it abstracts entirely from the semantic content of thought.

One of the most important philosophers of the latter half of the twentieth century, Donald Davidson explored a wide range of fundamental topics in meta- physics, epistemology, ethics, and the philosophies of action, mind, and language. His impact on contemporary philosophy is second only to that of his teacher W. V. O. Quine, who, along with Alfred Tarski, exerted the greatest influence on him. Given the range of his contributions, his work emerges as surprisingly systematic, an expression and working out of a number of central guiding ideas. Among his most important contributions are 1. his defense of the common sense view that reasons, those beliefs and desires we cite in explaining our actions, are also causes of them [11], 2. his groundbreaking work in the theory of meaning, and his proposal, based on Tarski’s work on recursive truth definitions for formal languages, for how to formulate a compositional semantic theory for a natural language [29, 46, 47, 50, 51], 3. his development of the project of radical interpretation as a vehicle for investigating questions about meaning and the psychological attitudes involved in understanding action [7, 15, 42, 44, 48], 309 310 Ernest Lepore and Kirk Ludwig 4.

  • 1 24.400 Proseminar in Philosophy I Fall 2003 Notes on Miscellanous
    1 24.400 Proseminar in philosophy I Fall 2003 Notes on miscellanous topics—II Frege’s assertion sign See the attached quote from Geach (from Kenny’s Frege). The concept horse, and the grammatical predicate ‘is red’ See the attached excerpt from Kenny, Frege. A prize is available for an explanation of Kenny’s point. The view of “On Sense and Reference” According to the Begriffsschrift (§8), identity is a relation between names, not the referents of names (objects). According to the standard interpretation (see Beaney, 21-2), in “On Sense and Reference” Frege rejects his earlier name view in favor of the object view; identity is now taken to be a relation between objects, and the informativeness of identity statements is explained in terms of a difference in sense. According to Thau and Caplan, “What’s Puzzling Gottlob Frege?”, CJP 31, 2001, Frege doesn’t reject the name view in “On Sense and Reference”. Heck responds on behalf of orthodoxy (you can find this on his website), and Thau and Caplan respond to Heck (forthcoming). The Mates Problem In 1950, Benson Mates pointed out that (by way of criticizing Carnap) that instances of: (1) Nobody doubts that whoever believes that D, believes that D. (2) Nobody doubts that whoever believes that D, believes that D´. 2 can apparently differ in truth value when the substituends for ‘D’ and ‘D´’ differ only by synonyms (e.g. ‘the holiday lasted for a fortnight’, ‘the holiday lasted for a period of fourteen days’). This raises obvious problems for the view that the meaning of a sentence is determined by the meanings of its parts and the way they are put together.
