Possible world semantics considers not only what an expression actually refers to but also what it might have referred to in counterfactual circumstances. This has proven exceptionally useful both inside and outside philosophy. The way this is achieved is by using intensions. An intension of an expression is a function that assigns to each possible world the reference of the expression in that world. However, the specific intension of terms has been subject to frequent disputes. How is one to determine (...) the intension of a term? Carnap has shown how the intension of a term depends on the type of that term. Two-dimensional semantics has shown how intensions also depend on the actual state of affairs. I will show how, in addition, intensions are no less dependent on metaphysical criteria of identity. Furthermore, I will reveal how these three factors interact to fix the exact intension of a term. In other words, I propose an outline of the overall mechanism by which intensions are being fixed. (shrink)

It is generally assumed that if it is possible to believe that p without believing that q, then there is some difference between the object of the thought that p and the object of the thought that q. This assumption is challenged in the present paper, opening the way to an account of epistemic opacity that improves on existing accounts, not least because it casts doubt on various arguments that attempt to derive startling ontological conclusions from seemingly innocent epistemic premises.

The nonexistence of fictional entities does not seem incompatible with their possible existence. The aim of this paper is to give an account of the intuitive truth of statements of possible existence involving fictional proper names in an actualist framework. After having clarified the opposition between a possibilist and an actualist approach of possible wolds, I distinguish fictional individuals from fictional characters and the fictional use of fictional proper names from their metafictional use. On that basis, statements of possible existence (...) involving fictional proper names literally say of fictional characters conceived as abstract objects that they might have been exemplified.

Orthodoxy has it that knowledge is absolute—that is, it cannot come in degrees. On the other hand, there seems to be strong evidence for the gradability of know-how. Ascriptions of know-how are gradable, as when we say that one knows in part how to do something, or that one knows how to do something better than somebody else. When coupled with absolutism, the gradability of ascriptions of know-how can be used to mount a powerful argument against intellectualism about know-how—the view (...) that know-how is a species of propositional knowledge. This essay defends intellectualism from the argument of gradability. It is argued that the gradability of ascriptions of know-how should be discounted as a rather superficial linguistic phenomenon, one that can be explained in a way compatible with the absoluteness of the state reported.

First-order formalisations are often preferred to propositional ones because they are thought to underwrite the validity of more arguments. We compare and contrast the ability of some well-known logics—these two in particular—to formally capture valid and invalid arguments. We show that there is a precise and important sense in which first-order logic does not improve on propositional logic in this respect. We also prove some generalisations and related results of philosophical interest. The rest of the article investigates the results’ philosophical (...) significance. A first moral is that the correct way to state the oft-cited superiority of first-order logic vis-`a-vis propositional logic is more nuanced than often thought. The second moral concerns semantic theory; the third logic’s use as a tool for discovery. A fourth and final moral is that second-order logic’s transcendence of first-order logic is greater than first-order logic’s transcendence of propositional logic. (shrink)

The point of formalisation is to model various aspects of natural language. Perhaps the main use to which formalisation is put is to model and explain inferential relations between different sentences. Judged solely by this objective, a formalisation is successful in modelling the inferential network of natural language sentences to the extent that it mirrors this network. There is surprisingly little literature on the criteria of good formalisation, and even less on the question of what it is for a formalisation (...) to mirror the inferential network of a natural language or some fragment of it. This paper takes some exploratory steps towards a quantitative account of the main ingredient in the goodness of a formalisation. We introduce and critically examine a mathematical model of how well a formalisation mirrors natural-language inferential relations. (shrink)

It is usually taken for granted that a necessary condition for knowing that P is the truth of P. It may therefore be claimed that if we assume that we gain some kind of knowledge through fiction (let us call it fictional knowledge) of P*, then P* should be true—in at least a certain sense. My hypothesis is that this assumption grounds the different ways adopted by philosophers for attributing truth-conditions to fictional sentences. My claim in this work is that (...) fictional sentences do not have truth-values and truth-conditions, but I want to maintain that we gain some kind of knowledge through fiction: to this aim, I will characterize the objective content of fictional sentences not in terms of truth-conditions (which are usually described by appealing to rules of the language or rules of interpretation of language independent of the actual users), but in dispositional terms and I will define a necessary condition for fictional knowledge accordingly.

Evidence is drawn together to connect sources of inconsistency that Frege discerned in his foundations for arithmetic with the origins of the paradox derived by Russell in "Basic Laws" I and then with antinomies, paradoxes, contradictions, riddles associated with modal and intensional logics. Examined are: Frege's efforts to grasp logical objects; the philosophical arguments that compelled Russell to adopt a description theory of names and a eliminative theory of descriptions; the resurfacing of issues surrounding reference, descriptions, identity, substitutivity, paradox in (...) the debates concerning modal and intensional logics; the development of the New Theory of Reference. I consider this to be the philosophical ground upon which the debates regarding that theory should take place. (shrink)

This paper embeds a theory of proper names in a general approach to singular reference based on type‐free property theory. It is proposed that a proper name “N” is a sortal common noun whose meaning is essentially tied to the linguistic type “N”. Moreover, “N” can be singularly referring insofar as it is elliptical for a definite description of the form the “N” Following Montague, the meaning of a definite description is taken to be a property of properties. The proposed (...) theory fulfils the major desiderata stemming from Kripke's works on proper names. (shrink)

The hierarchical analysis of existence attribution is Fregean in its endorsement of senses, understood as guises. Furthermore, the hierarchical analysis makes an essential use of the Russellian analysis (9′) as a means to understand what it is for a sense to present a given entity (cf. biconditional (11) above). The hierarchical analysis, on the other hand, is more general than the Russellian one and hence - in accordance with natural language usage - allows for a wider range of applications.

According to the received view, descriptivism is a dead end in an attempt to account for singular reference by proper names, indexicals and possibly even incomplete descriptions, for they require referentialism. In contrast to this, I argue for an application of the former to all kinds of singular terms, indexicals in particular, by relying on a view of incomplete descriptions as elliptical in a pragmatic sense. I thus provide a general analysis of singular reference. The proposed approach is in line (...) with the classical theory of propositions, except for admitting “private” ones with subjective mental entities as constituents. On the other hand, there is no commitment to singular Russellian propositions with ordinary objects as constituents and in general to meanings that cannot be “in the mind”. (shrink)

There are many data suggesting that we should acknowledge fictional entities in our ontological inventory, in spite of the paraphrasing strategies that Russell’s theory of descriptions can offer. Thus the realist attitude toward fictional entities of Meinongian and artifactualist accounts may seem well-motivated. Yet, these approaches infringe the Russellian “robust sense of reality.” A different realist account is proposed here, one that is compatible with the Russellian “robust sense of reality” in that it identifies fictional entities with denoting concepts, understood (...) as properties of properties.

Konolige''s technical notion of belief based on deduction structures is briefly reviewed and its usefulness for the design of artificial agents with limited representational and deductive capacities is pointed out. The design of artificial agents with more sophisticated representational and deductive capacities is then taken into account. Extended representational capacities require in the first place a solution to the intensional context problems. As an alternative to Konolige''s modal first-order language, an approach based on type-free property theory is proposed. It considers (...) often neglected issues, such as the need for a more general account of thede dicto-de re distinction, and quasi-indicators. Extended deductive capacities require a subdivision of Konolige''s notion of belief into two distinct technical notions,potential anddispositional belief. The former has to do with what an artificial agent could in principle come to actively believe, given enough time and its specific logical competence; the latter with what an agent can be assumed to believe with respect to a specific goal to be fulfilled.

"Truth-conditional semantics is by far the best-known philosophical contribution of Donald Davidson. The main idea of this approach is to explain the concept of meaning by appeal to the concept of truth. Accordingly, we understand a sentence s of a natural language L, if and only if, we know its truth-conditions. Challenging in its nature, this proposal immediately caught the attention of the philosophical community, being equally appreciated and criticized. The aim of this paper is to argue that Davidson’s approach (...) is too optimistic in its goals. In my view, truth-conditional semantics is unlikely to be the best way to shed light on the concept of meaning. By appealing to Tarski’s semantic conception of truth and assuming a primitive concept of truth, this perspective leaves too many questions unanswered and thus proves its limits. Keywords: Donald Davidson, meaning, truth, Truth-Conditional Semantics. ". (shrink)

In this paper, the authors show that there is a reading of St. Anselm's ontological argument in Proslogium II that is logically valid (the premises entail the conclusion). This reading takes Anselm's use of the definite description "that than which nothing greater can be conceived" seriously. Consider a first-order language and logic in which definite descriptions are genuine terms, and in which the quantified sentence "there is an x such that..." does not imply "x exists". Then, using an ordinary logic (...) of descriptions and a connected greater-than relation, God's existence logically follows from the claims: (a) there is a conceivable thing than which nothing greater is conceivable, and (b) if <em>x</em> doesn't exist, something greater than x can be conceived. To deny the conclusion, one must deny one of the premises. However, the argument involves no modal inferences and, interestingly, Descartes' ontological argument can be derived from it. (shrink)

Two general principles have played a crucial role in the recent debate on concepts. On the one hand, we want to allow different subjects to have the same concepts, thus accounting for concept publicity: concepts are ‘the sort of thing that people can, and do, share’. On the other hand, a subject who finds herself in a so-called ‘Frege case’ appears to have different concepts for the same object: for instance, Lois Lane has two distinct concepts SUPERMAN and CLARK KENT (...) which refer to the same person. Several theories have tried to meet both of these constraints at the same time. But should we really try to satisfy both principles? This paper will argue that the traditional project of fulfilling these two constraints has been a misguided one. Through a variation on classic identity mistake cases, I will show that our two desiderata are inconsistent: it would thus be impossible to incorporate both of them in our best theory of concepts.

We all learn about the mistake of treating ‘nothing’ as if it were a term standing for something; but is it a mistake to treat it as an empty term, denoting nothing? We argue not, and we introduce ‘zilch’, defined as ‘the non-self-identical thing’, as a term which is empty as a matter of logical necessity. We contrast its behaviour with that of the quantifier ‘nothing’, and illustrate its uses. We use the same idea to vindicate Locke’s, Descartes’ and Hume’s (...) handling of ‘nothing’, and we show how Heidegger’s ‘das Nichts nichtet’ comes out as logically true. (shrink)

What kind of reference (if any) do terms such as “pencil,” “chair,” “television,” and so on have? On the matter, a de-bate between directly referential theorists and descriptiv-ist theorists is open. It is largely acknowledged that natural kind terms (such as “water,” “gold,” “tiger,” etc.) are directly referential expressions (cf. Putnam,1975). That is, they are expressions whose reference is determined by their refer-ents' nature, independent of whether we know or will ever know what this nature is. However, it does not (...) seem like-wise convincing that all artifactual kind terms (like “pen-cil,” “chair,” “television,” etc.) semantically behave the same. Terms for artifactual kinds seem more likely to be subjected to a descriptivist view, that is, definable not by links to their extensions' nature but in terms of conjunctions or clusters of properties. In his celebrated “The Meaning of ‘Meaning’” (1975), Hilary Putnam originated the mentioned debate by arguing that artifactual kind terms also refer directly. Thus, the discussion ultimately revolves around establishing whether artifactual and natural kind terms are both directly referential expressions. The authors engaged in this debate have tried to argue in favor of (or against) Putnam's proposal by highlighting the similarities (or differences) between nat-ural vis-à-vis artifactual kind words and their respective ref-erents. This paper aims to provide a thorough and reasoned overview of the debate at stake, pointing out trends and problems associated with each proposed account. (shrink)

In his paper “St. Anselm’s ontological argument succumbs to Russell’s paradox” Christopher Viger presents a critique of Anselm’s Argument from the second chapter of Proslogion. Viger claims there that he manages to show that the greater than relation that Anselm used in his proof leads to inconsistency. I argue firstly, that Viger does not show what he maintains to show, secondly, that the flaw is not in the nature of Anselm’s reasoning but in Viger’s (mis)understanding of Anselm as well as (...) in Viger’s (mis)application of some set-theoretical notions. I also describe some features of Anselmian greater than relation, which indeed plays a crucial role in his Ontological Argument. Last but not least, I present the Argument itself. (shrink)

This article focuses on Jonathan Berg’s Theory of Direct Belief as presented in his 2012 book Direct Belief. An Essay on the Semantics, Pragmatics, and Metaphysics of Belief. After regimenting Berg’s key theses and discussing the sources of their general unpopularity, I proceed to reconstruct Berg’s book-length argument for his conclusions. I here make explicit that Berg relies on a range of strong meta-semantic principles and assumptions. I conclude that even if Berg has brought considerable methodological rigor to the on-going (...) debate over the semantics of natural language attitude ascriptions, and has proposed an elegant and consistent theory, he has not offered compelling reasons to accept his preferred methodological constraints in light of the difficulties, which those constraints impose upon attitude ascription semantics.

This essay examines some of the arguments in David Deutsch's book The Fabric of Reality , chief among them its case for the so-called many-universe interpretation of quantum mechanics (QM), presented as the only physically and logically consistent solution to the QM paradoxes of wave/particle dualism, remote simultaneous interaction, the observer-induced 'collapse of the wave-packet', etc. The hypothesis assumes that all possible outcomes are realized in every such momentary 'collapse', since the observer splits off into so many parallel, coexisting, but (...) epistemically non-interaccessible 'worlds' whose subsequent branchings constitute the lifeline-or experiential world-series- for each of those proliferating centres of consciousness. Although Deutsch concedes that his 'multiverse' theory is counter-intuitive, he none the less takes it to be borne out beyond question by the sheer observational/predictive success of QM and the conceptual dilemmas that supposedly arise with alternative (single-universe) accounts. Moreover, he claims the theory resolves a range of longstanding philosophical problems, notably those of mind/body dualism, the various traditional paradoxes of time, and the freewill/determinism issue. The essay suggests on the contrary, that Deutsch unwittingly transposes into the framework of presentday quantum debate speculative themes from the history of rationalist metaphysics, often with bizarre or philosophically dubious results, and that he rules out at least one promising rival account, namely Bohm's 'hidden variables' theory. It goes on to consider reasons for resistance to that theory among proponents of the 'orthodox' (Copenhagen) doctrine, and for the strong anti-realist, at times even irrationalist bias that has characterized much of this discussion since Bohr's debates with Einstein about quantum non-locality, observer-intervention, and the limits of precise measurement. Finally, the contrast is pointed out between Deutsch's ontologically extravagant use of the many-worlds hypothesis (akin to certain ideas advanced by speculative metaphysicians from Leibniz down) and those realist modes of counterfactual reasoning- e.g. in Kripke and the early Putnam- which deploy similar arguments to very different causal-explanatory ends.

In this essay, I offer a critical evaluation of Hilary Putnam's writings on epistemology and philosophy of science, in particular his engagement with interpretative problems in quantum mechanics. I trace the development of his thinking from the late 1960s when he adopted a strong causal-realist position on issues of meaning, reference, and truth, via the "internal realist" approach of his middle-period writings, to the various forms of pragmatist, naturalized, or "commonsense" epistemology proposed in his latest books. My contention is that (...) Putnam's retreat from a full-fledged realist outlook has been prompted in large part by his belief that it cannot possibly be reconciled with the implications of quantum mechanics for our understanding of processes and events in the subatomic domain. However, I suggest, this response should be seen as premature given the range of as-yet unresolved problems with quantum mechanics on the orthodox (Copenhagen) interpretation and also the existence of an alternative account - David Bohm's hidden-variables theory - which perfectly matches the established predictive-observational results while providing a credible realist ontology. I also examine Putnam's case for adopting a nonstandard (three-valued) "quantum logic" in relation to the thinking of other philosophers - Michael Dummett among them - who have espoused a more global or doctrinaire version of anti-realism. I conclude that Putnam's early (causal-realist) position is by no means untenable in light of the various arguments that he now takes as counting decisively against it. (shrink)

By means of a reductio argument, Wittgenstein’s Tractatus calls into question the very idea that we can represent logical form. My paper addresses three interrelated questions: first, what conception of logical form is at issue in this argument? Second, whose conception of logic is this argument intended to undermine? And third, what could count as an adequate response to it? I show that the argument construes logical form as the universal, underlying correlation of any representation and the reality it represents. (...) I further show that the argument seeks to undermine core commitments of Frege’s and Russell’s. But the reductio, as I read it, is not intended to establish the falsity of any of their specific assumptions. Rather, its aim is to make manifest the indeterminacies that underlie the language in which these assumptions are framed, and establish the need for a transformation of that language. So understood, Wittgenstein’s argument exemplifies his idea that philosophy is not a theory, but an activity of elucidation. The interpretation I propose bears on one of the central debates in the literature, namely how we should understand Wittgenstein’s contention that his elucidations succeed despite being nonsensical.

This paper examines Ralph Barton Perry's analysis of the ‘ego-centric predicament’. It will be shown that Perry convincingly argued against prevailing contemporary versions of idealism and that it makes perfectly good sense to consider him a precursor of subsequent trends in American analytic philosophy. Perry's appraisal and promotion of the contemporary logic of relations in the framework of early twentieth-century American neorealism provides further evidence of his being a proto-analytic philosopher. His personal acquaintance with Bertrand Russell proved instructive in this (...) regard. On the whole, Perry's distinctive approach to philosophy was instrumental in establishing the analytic style of reasoning in the United States. This paper is devoted to substantiating this claim. It is thus hoped that a clearer picture of early twentieth-century American philosophy will begin to emerge. (shrink)

The leading accounts of the ethics of proxy decision making implicitly draw on internalist conceptions of the philosophy of mind, or so this essay tries to demonstrate. Using the views of Ronald Dworkin as its jumping‐off point, the essay argues that accepting the sort of externalism associated with writers such as Putnam and Burge would alter Dworkin's conclusions concerning how we should respond to the current or precedent decisions of people suffering from dementia. Building on the views of Agnieszka Jawarska, (...) it argues that accepting “active” externalism à la Clark and Chambers would provide currently competent people with new resources for establishing the authority of their present values over inconsistent values they might come to entertain should they become demented.

In a recent article in this journal (Foundations of Chemistry, 7 (2005), 125–148) Lombardi and Labarca call into question a thesis of ontological reduction to which several writers on reduction subscribe despite rejecting a thesis of epistemological reduction.

I suggest that it is not necessary to go so far, and that a more critical view of the ontological reduction espoused by the authors they criticise circumvents the need (...) to resort to their radical alternative.

Despite its enormous popularity, Russell’s theory of definite descriptions has received various criticisms. Two of the most important objections against this theory are those arising from the Argument from Incompleteness and the Argument from Donnellan’s Distinction. According to the former although a speaker may say something true by assertively uttering a sentence containing an incomplete description , on the Russellian analysis such a sentence expresses a false proposition; so, Russell’s theory cannot adequately deal with such sentences. According to the latter (...) objection a descriptive sentence is actually ambiguous—it expresses a general proposition when the description contained in it is used attributively, and a singular proposition when the description in question is used referentially; Russell’s theory is inadequate as it fails to capture this ambiguity and offers an analysis according to which a descriptive sentence expresses only a general proposition. These objections are examined in the present dissertation. It is shown here that these objections arise from: (i) ignoring the distinction between the meaning of a sentence and the assertions made by using it, (ii) the failure to distinguish between the semantic meaning of a sentence and the pragmatic meaning with which it is used on a particular occasion. To make the distinction mentioned in (i), a significant part of Scott Soames’ theory concerning meaning and assertions has been adopted in this dissertation; and, to make the distinction mentioned in (ii), a test, namely the cancellability test, and two Distinguishing Criteria, namely DC-1 and DC-2, have been developed here. It has been argued here that if we properly make the relevant distinctions, then we will find that: (a) the phenomenon cited by the Argument from Incompleteness can be well explained keeping the Russellian analysis of descriptive sentences intact, (b) the phenomenon arising from the Argument from Donnellan’s Distinction raises an issue of pragmatics and is irrelevant to Russell’s semantic analysis of descriptive sentences. So, none of the above criticisms poses a genuine threat to Russell’s theory of definite descriptions; his theory actually provides, to a large extent, a correct semantic analysis of descriptive sentences.

Even though Richard Routley is known as a proponent of so-callednuclear Meinongianism (in his terminology, noneism), the details of hisview in Exploring Meinong’s Jungle and Beyond (1980) have not attractedmuch attention. In this paper, I critically examine two notablebut less known features of Meinongianism in Routley (1980) which particularlyconcern a core claim of nuclear Meinongianism that so-calledCharacterization Principle (CP) is applicable to nuclear properties(in his terminology, characterizing properties) but not to extranuclearproperties (in his terminology, noncharacterizing properties): The firstone is his (...) ‘double determination’ argument for restricting the class ofproperties to which CP is applicable; and the second is his expansionof the class of nuclear properties in terms of the supposition operator s.Firstly, I will show that the double determination argument fails, since,for some extranuclear properties, the argument fails to justify that CPis not applicable to them, and, moreover, the argument unintendedlyshows that CP is not applicable to some nuclear properties. Secondly,based on the idea that the supposition operator, combined with anyproperty f, forms the intensional property of being assumed to havef, I will give a formal treatment of the supposition operator withinthe framework of world semantics. We will see that this interpretationgoes beyond Routley’s original nuclear Meinongianism and assimilateshis view with modal Meinongianism proposed by Priest (2005, 2016). (shrink)

This paper aims at bringing together two debates in metaphysics that so far have been kept separate: the debate about determinism vs. indeterminism as de re modality on the one hand, and the debate about persistence on the other hand. Both debates significantly involve talk of things. We will show that working out a proper semantics for singular terms and an accompanying theory of things, motivated by considerations of quantified modal logic, can significantly further the persistence debate. We will use (...) our semantic framework to give an argument in support of the endurantist position as the best theory of persistence. (shrink)

Discussions about singular cognition, and its linguistic counterpart, are by no means exclusive to contemporary philosophy. In fact, a strikingly similar discussion, to which several medieval texts bear witness, took place in the late Middle Ages. The aim of this article is to partly reconstruct this medieval discussion, as it took place in Parisian question-commentaries on Aristotle’s De anima, so as to show the progression from the rejection of singular intellection in Siger of Brabant to the descriptivist positions of John (...) Duns Scotus and John of Jandun, and finally to the singularism of John Buridan. All these authors accept some kind of intellectual access to individuals. Therefore, the conundrum is not whether we have some kind of intellectual knowledge of individuals, but rather whether we can know them singularly. This article begins by presenting the crucial obstacle to singular intellection in Siger. Thereafter, the author shows that Jandun and Scotus depart in fundamental ways from Siger’s account, but that for them the intellection of individuals is of a general character. Finally, she proposes that Buridan is a genuine singularist. (shrink)

One challenge that the proponent of the Fregean theory of definite descriptions has to meet is to account for those truth-value intuitions that do not match the predictions of her theory. What needs an explanation is why sentences such as ‘The king of France is sitting in that chair’ [pointing at an empty chair] are intuitively false, while semantically truth-valueless. The existence of such cases was pointed out by Strawson :216–231, 1954) and Russell :385–389, 1957), and much discussed in the (...) subsequent literature. The standard pragmatic explanation that Fregeans have proposed :113–122, 1993; von Fintel, Descriptions and beyond, Oxford University Press, Oxford, 2004; Elbourne, Definite descriptions, Oxford University Press, Oxford, 2013) invokes an epistemic strategy of verification of the utterance of the sentence. I raise three objections to this strategy, two concerning its descriptive adequacy, and one concerning the motivation offered for the approach. Finally, I propose an alternative account that relies on an inferential pattern that leads to the relevant truth-value judgements in certain contextually specified conditions. (shrink)

In this paper, I argue that, just as the problem of unconceived alternatives provides a basis for a New Induction on the History of Science to the effect that a realist view of science is unwarranted, the problem of unconceived objections provides a basis for a New Induction on the History of Philosophy to the effect that a realist view of philosophy is unwarranted. I raise this problem not only for skepticism’s sake but also for the sake of making a (...) point about philosophical argumentation, namely, that anticipating objections to one’s claim is not the same as supporting one’s claim. In other words, defending p from objections does not amount to support or evidence for p. This, in turn, presents dialectical and pragma-dialectical approaches to argumentation with the following question: does proper argumentation require that arguers anticipate and respond to unconceived objections?

The author investigates which methods of naming objects are possible in the language of physics on the basis of the real physical conditions and to which extend objects thereby can be identified. It is shown that in the language of classical physics naming by designation is always possible. But this implies only the temporal identity of objects, not the "trans - world" - identity, which is important for modalities. In the language of quantum physics naming by designation is no longer (...) applicable to individuals but only to classes of equivalent objects. And for these classes temporal identity as well as the "trans - world" - identity can be produced, which means that an adequate semantics can be specified for the concept of possibility necessary in this language.

In this paper, I will show to what extent we can use our modern understanding of the Square of Opposition in order to make sense of Kant 's double standard solution to the cosmological antinomies. Notoriously, for Kant, both theses and antitheses of the mathematical antinomies are false, while both theses and antitheses of the dynamical antinomies are true. Kantian philosophers and interpreters have criticized Kant 's solution as artificial and prejudicial. In the paper, I do not dispute such claims, (...) but I show that our modern understanding of the Square of Opposition enables us to more naturally deliver the result Kant was aiming at. Accordingly, the paper does not pretend to be exegetically accurate. It is an attempt to revise the antinomies with the help of standard classical logic. And although such a revision entails some re-interpretation, in the end, it will actually help to unveil some of Kant 's thoughts. (shrink)

In “Kant on Existence, Predication, and the Ontological Argument”, Hintikka argues that the so-called “Kant–Frege view” is wrong, for its supporters erroneously assume that for Kant ‘is’ is ambiguous. In this paper, I will first critically evaluate Hintikka’s arguments against the Kant–Frege view. Then, I will attempt to prove that Kant’s claim that existence is not a real predicate and Frege’s claim that existence is a quantifier are in fact logically interdependent. Finally, I will use the Kant–Frege view in order (...) to reconcile the various claims that Kant makes about existence. (shrink)

The author examines the epistemological project of analytic philosophy, which went through stages of transformation marked by the influence of Frege and Russell. The article emphasizes the main points of the first stage of analytic philosophy, during which the sphere of experience merged with language. The next stage defines a new subject - Wittgenstein's "language subject". According to the author, this subject of speech makes decisions about the sense or absurdity of sentences based on logical form and belongs to the (...) transcendental subject of speech in general. But in the end, the epistemological project of analytic philosophy moved to new directions in which questions about experience lost their relevance. (shrink)
