Saul Kripke is one of the most important and influential philosophers of the late twentieth century. He is also one of the leading mathematical logicians, having done seminal work in areas including modal logic, intuitionistic logic and set theory. Although much of his work in logic has philosophical significance, it will not be discussed here. Kripke’s main contributions fall in the areas of metaphysics, philosophy of language, epistemology, philosophy of mind and philosophy of logic and mathematics. He is particularly well known for his views on and discussions of the following topics: the concepts of necessity, identity and ‘possible worlds’; ‘essentialism’ – the idea that things have significant essential properties; the question of what determines the referent of an ordinary proper name and the related question of whether such names have meanings; the relations among the concepts of necessity, analyticity, and the a priori; the concept of belief and its problems; the concept of truth and its problems; and scepticism, the idea of following a rule, and Ludwig Wittgenstein’s ‘private language argument’. This entry will be confined to the topics of identity, proper names, necessity and essentialism.

Saul Kripke is one of the most influential philosophers to have written on logic, metaphysics, the philosophy of language, and the philosophy of mind in the twentieth century. In logic, he made an early and seminal contribution to the formal treatment of modality, that is, thoughts and statements about how things might have been or must have been (§2). In metaphysics, his work on modality has also been important, contributing as it did to the revival of the Aristotelian idea that the ways a thing might have been or must be (its contingent and its essential properties) were features of that very thing itself. This was in opposition to the view, prevalent in various forms throughout the first half of the twentieth century, that necessity was always relative to some classification or description of the object (§3). In the philosophy of language, he attacked– – in Naming and Necessity – the Russellian idea that proper names are simply abbreviated descriptions of the things that they name, arguing that instead they can refer directly to things via causal connections of which the users of language might be unaware (§4). Again, in the philosophy of language, his work on Wittgenstein on rule-following evinced what seemed to be a radical and devastating skepticism about the very possibility of the meaningful use of language (§6). And his proposed solution constituted a novel re-interpretation of Wittgenstein’s "private language argument," one that seemed to reveal the essentially social character of language (§8). In the philosophy of mind, he used the semantic machinery developed in Naming and Necessity to revive the long-discredited Cartesian argument against identifying mental and physical states (§5). Saul Kripke has also written ground-breaking works on the theory of truth (1975), the theory of knowledge (2011), and the semantics of fictional discourse (2013).

The term “philosophy of language” is intrinsically paradoxical: it denominates the main philosophical current of the 20th century but is devoid of any univocal definition. While the emergence of this current was based on the idea that philosophical questions were only language problems that could be elucidated through a logico-linguistic analysis, the interest in this approach gave rise to philosophical theories that, although having points of convergence for some of them, developed very different philosophical conceptions. The only constant in all these theories is the recognition that this current of thought originated in the work of Gottlob Frege (b. 1848–d. 1925), thus marking what was to be called “the linguistic turn.” Despite the theoretical diversity within the philosophy of language, the history of this current can however be traced in four stages: The first one began in 1892 with Frege’s paper “Über Sinn und Bedeutung” and aimed to clarify language by using the rules of logic. The Fregean principle underpinning this program was that we must banish psychological considerations from linguistic analysis in order to avoid associating the meaning of words with mental pictures or states. The work of Frege, Bertrand Russell (1872–1970), George Moore (1873–1958), Ludwig Wittgenstein (1921), Rudolf Carnap (1891–1970), and Willard Van Orman Quine (1908–2000) is representative of this period. In this logicist point of view, the questions raised mainly concerned syntax and semantics, since the goal was to define a formalism able to represent the structure of propositions and to explain how language can describe the world by mirroring it. The problem specific to this period was therefore the function of representing the world by language, thus placing at the heart of the philosophical debate the notions of reference, meaning, and truth. The second phase of the philosophy of language was adumbrated in the 1930s with the courses given by Wittgenstein (1889–1951) in Cambridge (The Blue and Brown Books), but it did not really take off until 1950–1960 with the work of Peter Strawson (1919–2006), Wittgenstein (1953), John Austin (1911–1960), and John Searle (1932–). In spite of the very different approaches developed by these theorists, the two main ideas that characterized this period were: one, that only the examination of natural (also called “ordinary”) language can give access to an understanding of how language functions, and two, that the specificity of this language resides in its ability to perform actions. It was therefore no longer a question of analyzing language in logical terms, but rather of considering it in itself, by examining the meaning of statements as they are used in given contexts. In this perspective, the pivotal concepts explored by philosophers became those of (situated) meaning, felicity conditions, use, and context. The beginning of the 1970s initiated the third phase of this movement by orienting research toward two quite distinct directions. The first, resulting from the work on proper names, natural-kind words, and indexicals undertaken by the logician philosophers Saul Kripke (1940–), David Lewis (1941–2001), Hilary Putnam (1926–2016), and David Kaplan (1933–), brought credibility to the semantics of possible worlds. The second, conducted by Paul Grice (1913–1988) on human communicational rationality, harked back to the psychologism dismissed by Frege and conceived of the functioning of language as highly dependent on a theory of mind. The focus was then put on the inferences that the different protagonists in a linguistic exchange construct from the recognition of hidden intentions in the discourse of others. In this perspective, the concepts of implicitness, relevance, and cognitive efficiency became central and required involving a greater number of contextual parameters to account for them. In the wake of this research, many theorists turned to the philosophy of mind as evidenced in the late 1980s by the work on relevance by Dan Sperber (1942–) and Deirdre Wilson (1941–). The contemporary period, marked by the thinking of Robert Brandom (1950–) and Charles Travis (1943–), is illustrated by its orientation toward a radical contextualism and the return of inferentialism that draws strongly on Frege. Within these theoretical frameworks, the notions of truth and reference no longer fall within the field of semantics but rather of pragmatics. The emphasis is placed on the commitment that the speakers make when they speak, as well as on their responsibility with respect to their utterances.

This book weaves together themes from natural ontology, philosophy of mind, philosophy of language and information, areas of inquiry that have not recently been treated together. The sprawling topic is Kant’s how is knowledge possible? but viewed from a contemporary naturalist standpoint. The assumption is that we are evolved creatures that use cognition as a guide in dealing with the natural world, and that the natural world is roughly as natural science has tried to describe it. Very unlike Kant, then, we must begin with ontology, with a rough understanding of what the world is like prior to cognition, only later developing theories about the nature of cognition within that world and how it manages to reflect the rest of nature. And in trying to get from ontology to cognition we must traverse another non-Kantian domain: questions about the transmission of information both through natural signs and through purposeful signs including, especially, language. Novelties are the introduction of unitrackers and unicepts whose job is to recognize the same again as manifested through the jargon of experience, a direct reference theory for common nouns and other extensional terms, a naturalist sketch of uniceptual—roughly conceptual— development, a theory of natural information and of language function that shows how properly functioning language carries natural information, a novel description of the semantics/pragmatics distinction, a discussion of perception as translation from natural informational signs, new descriptions of indexicals and demonstratives and of intensional contexts and a new analysis of the reference of incomplete descriptions.

AbstractOne of the most widely-discussed arguments against physcialism appeals to the conceivability of zombies, being which are physically or functionally identical to humans but which have no conscious experiences. Philip Goff (Philos Phenomenol Res 81(1): 119–139, 2010; Consci Cognit 21(2): 742–746, 2012a; in Sprevak M, Kallestrup J (eds) New waves in philosophy of mind. Palgrave, 2014) has recently presented a number of different anti-physicalist arguments appealing to the conceivability of ghosts, entities whose nature is exhausted by their being conscious. If ghosts are conceivable, this would rule out a priori physicalism. If the conceivability of ghosts entails that they are metaphysically possible, then this forms the basis for arguments against a posteriori physicalism. Drawing on work on conceivability by Peter Kung (Philos Phenomenol Res 81(3):620–663, 2010, Noûs 50(1): 90–120, 2016) and my own discussion of arguments which appeal to the conceivability of zombies (O’Conaill in Mihretu P Guta (ed) Consciousness and the ontology of properties. Routledge, New York, 2019), I shall argue that ghosts are conceivable, but that what allows us to conceive of them (our ability to make certain stipulations about the scenarios we conceive) undermines the belief that conceivability is a reliable guide to possibility. While this does not undermine Goff’s argument against a priori phyiscalism, it suggests that a posteriori physicalists need not be haunted by ghosts.

Abstract The present study deals with the problem of the acquisition of language in children in the light of rationalist philosophy of mind and philosophy of language. The main objective of the paper is to present the way Gerauld de Cordemoy’s views on the nature of language, including its socio-linguistic aspects, and on the process of speech acquisition in children are reflected in contemporary writings on how people communicate with each other. Reflections on 17th-century rationalist philosophy of mind and the latest research conducted within the field of cognitive abilities of human beings indicate that between those two spheres many similarities could be discerned in terms of particular stages of the development of speech and its physical aspects.


Mental fragmentation is the thesis that the mind is fragmented, or compartmentalized. Roughly, this means that an agent’s overall belief state is divided into several sub-states—fragments. These fragments need not make for a consistent and deductively closed belief system. The thesis of mental fragmentation became popular through the work of philosophers like Christopher Cherniak, David Lewis, and Robert Stalnaker in the 1980s. Recently, it has attracted great attention again. This volume is the first collection of essays devoted to the topic of mental fragmentation. It features important new contributions by leading experts in the philosophy of mind, epistemology, and philosophy of language. Opening with an accessible Introduction providing a systematic overview of the current debate, the fourteen essays cover a wide range of issues: foundational issues and motivations for fragmentation, the rationality or irrationality of fragmentation, fragmentation’s role in language, the relationship between fragmentation and mental files, and the implications of fragmentation for the analysis of implicit attitudes.

AbstractI argue for the claim that there are instances of a priori justified belief – in particular, justified belief in moral principles – that are not analytic, i.e., that cannot be explained solely by the understanding we have of their propositions. §1–2 provides the background necessary for understanding this claim: in particular, it distinguishes between two ways a proposition can be analytic, Basis and Constitutive, and provides the general form of a moral principle. §§3–5 consider whether Hume's Law, properly interpreted, can be established by Moore's Open Question Argument, and concludes that it cannot: while Moore's argument – appropriately modified – is effective against the idea that moral judgments are either (i) reductively analyzable or (ii) Constitutive-analytic, a different argument is needed to show that they are not (iii) Basis-analytic. Such an argument is supplied in §6. §§7–8 conclude by considering how these considerations bear on recent discussions of “alternative normative concepts”, on the epistemology of intuitions, and on the differences between disagreement in moral domains and in other a priori domains such as logic and mathematics.

This chapter examines three stories by Jorge Luis Borges: “Funes: His Memory,” “Averroës's Search,” and “Pierre Menard, Author of the Quixote.” Each of these highlights the intricate nature of concepts and replication in the broad sense. The common theme running through these three stories is the word–world relation and the problems this relation generates. In each story, Borges explores one aspect of the process of conceptualization, an endeavor that has engaged philosophers ever since ancient Greece and is still at the center of contemporary philosophy of language and philosophy of mind. Together, Borges's stories present a complex picture of concepts and processes of conceptualization.

Two years ago, Bob Mulligan and I empirically tested whether the Bank of Amsterdam, a prototypical central bank, had caused a boom-bust cycle in the Amsterdam commodities markets in the 1780s owing to the bank’s sudden initiation of low-fractional-re-serve banking (Guzelian & Mulligan 2015).1 Widespread criticism came quickly after we presented our data findings at that year’s Austrian Economic Research Conference. Walter Block representa-tively responded: «as an Austrian, I maintain you cannot «test» apodictic theories, you can only illustrate them».2 Non-Austrian, so-called «empirical» economists typically have no problem with data-driven, inductive research. But Austrians have always objected strenuously on ontological and epistemolog-ical grounds that such studies do not produce real knowledge (Mises 1998, 113-115; Mises 2007). Camps of economists are talking past each other in respective uses of the words «testing» and «eco-nomic theory». There is a vital distinction between «testing» (1) an economic proposition, praxeologically derived, and (2) the rele-vance of an economic proposition, praxeologically derived. The former is nonsensical; the latter may be necessary to acquire eco-nomic theory and knowledge. Clearing up this confusion is this note’s goal. Rothbard (1951) represents praxeology as the indispensible method for gaining economic knowledge. Starting with a Aristote-lian/Misesian axiom «humans act» or a Hayekian axiom of «humans think», a voluminous collection of logico-deductive eco-nomic propositions («theorems») follows, including theorems as sophisticated and perhaps unintuitive as the one Mulligan and I examined: low-fractional-reserve banking causes economic cycles. There is an ontological and epistemological analog between Austrian praxeology and mathematics. Much like praxeology, we «know» mathematics to be «true» because it is axiomatic and deductive. By starting with Peano Axioms, mathematicians are able by a long process of creative deduction, to establish the real number system, or that for the equation an + bn = cn, there are no integers a, b, c that satisfy the equation for any integer value of n greater than 2 (Fermat’s Last Theorem). But what do mathematicians mean when they then say they have mathematical knowledge, or that they have proven some-thing «true»? Is there an infinite set of rational numbers floating somewhere in the physical universe? Naturally no. Mathemati-cians mean that they have discovered an apodictic truth — some-thing unchangeably true without reference to physical reality because that truth is a priori.
