In this paper I will show why Carnap’s and Quine’s sympathy for the extensionality thesis can be considered equivalent to their concern with clear logical criteria for the manipulation—that is, identification and permutation—of empirical linguistic terms and also why Carnap renounced to the extensionality thesis in the late 1930s. Quine’s inclination to see extensionality as an avoidance of semantic confusion triggered his profound admiration for Carnap’s early works, which are very much of an extensionalist nature. But Quine realizes, as (...) early as the 1930s, that Carnap does not have the same resistance to admitting intensional objects. Already in the Aufbau (1928), Carnap’s phenomenalist and structuralist approach to knowledge, and his pragmatic approach to language systems, leads to the conclusion that the self-psyche and others’ psyche are not something, in principle, inaccessible to knowledge, and, therefore, that intensional—including intentional—objects could, in principle, be scientific objects. In addition to the historical development of semantics—which influenced Carnap—there are two fundamental reasons for Carnap’s increasing tolerance of intensional terminology and analysis in the philosophy of language. In the first place, Carnap thinks it possible to maintain a discourse on intensions without this leading to an ontological commitment to abstract intensional entities. Second, the behaviourist criteria for the identification of intensions that he offered demonstrates that he believed it possible to meet clear identification criteria for intensions. I will show why Carnap disagrees on these two points, in his semantic period, with Quine. (shrink)

Extensionalism, as I understand it here, is the view that physical reality consists exclusively of extensional entities. On this view, intensional entitities must either be eliminated in favor of an ontology of extensional entities, or be reduced to such an ontology, or otherwise be admitted as non-physical. In this paper I argue that extensionalism is a misguided philosophical doctrine. First, I argue that intensional phenomena are not confined to the realm of language and thought. Rather, the ontology of (...) such phenomena is intimately entwined with the ontology of properties. After providing some evidence to the popularity of extensionalism in contemporary analytic philosophy, I investigate the motivating reasons behind it. Considering several explanations, I argue that the main motivating reason is rooted in the identification of matter with extension, an identification which is one of the hallmarks of the mechanistic conception of nature inherited from the founding fathers of our modern scientific outlook. I then argue that such a conception is not only at odds with a robust ontology of properties but is also at odds with our best contemporary physics. Rather than vindicating extensionalism contemporary science undermines the position, and the lesson to be drawn from this surprising fact is that extensionalism needs no longer be espoused as a regulative ideal of naturalistic philosophy. I conclude by showing that the ontological approach to intensional phenomena advocated throughout the paper also gains support from an examination of the historical context within which ‘intension’ was first introduced as a semantic notion.

Paul Pietroski develops an iconoclastic account of linguistic meaning. Here, I invite him to say more about what it implies about the relations between language, truth, and conceptual content. Readers concerned with securing the objectivity of conceptual thought may be worried about his claims that typical concepts “have no extensions” and that they “fit one another better than they fit the world.” Others might applaud his anti‐extensionalism in natural‐language semantics but fear that his account re‐raises familiar problems about extensions (...) at the level of psychology.

This is what I hope is an illuminating, and to a certain degree, novel exposition of Montague Grammar. It is against many standard interpretations, and perhaps even against things Montague himself says at times. However, it makes more sense of how his various commitments fit together in a systematic way. Why, for instance, is it called "Montague Grammar" rather than "Montague Semantics," and what role does his commitment to Fregeanism plays in his conception of language? It is clear that he (...) is committed to the idea that function application is the fundamental mode of semantic composition, and that he is committed to an intensional framework. However, intensions have, since Carnap, been understood as nearly conceptually equivalent to functions from possible worlds to sets of individuals. But, in truth, possible worlds semantics is just dressed up extensional semantics. There are just more objects to go around to serve as inputs for functions, whatever we think of their ontological status. That is, possible worlds semantics is really a semantic reduction of intensional semantics achieved by expanding our ontological commitments. It would be difficult to make sense of Montague's strong commitment to Fregean semantics, if his notion of intension was that of Carnap's. According to my interpretation, Montague's notion of intension must be distinct from the version adopted by possible world semantics. Montague took seriously the idea that intensional semantics was something quite different from extensionalist semantics. The first was not reducible to the second semantically speaking. Just as Frege believed that meaning consisted of both sense and reference, so too did Montague. However, just as Frege also believed, Montague thought that sense and reference were systematically related. As I illustrate, interpreting Montague as adopting a different notion of intension can also resolve the apparent problem of distinguishing the difference in meaning between intensional equivalents. It might also enable us to draw a distinction in epistemic logic between an agent having contradictory beliefs and believing contradictions. (shrink)

In Defining Racism, I offer the first comprehensive examination of the philosophical literature on racism and argue for a new methodological approach that I call conventionalism. Framing my argument within this approach, I defend an oppression theory of racism. In this article, I will attempt to accomplish two goals: offer a reply to the thoughtful comments of my critics, and lay out the main argument and major themes of my book in an accessible manner. First, I will describe the philosophical (...) problem of defining “racism” and explain why I think a new methodological approach is necessary to address this problem. Second, I will present the moralist presupposition of my project and extend my oppression theory of racism in response to the challenge of assigning responsibility for oppression. Finally, I will address several criticisms to my prescriptive approach, including: my prescriptive approach unjustifiably privileges moralist explanation over social explanation ; the tool of semantic clarification, which my conventionalist framework draws upon, is inadequate for resolving conceptual disagreement; my call for scholars to negotiate the meaning of “racism” is unlikely to succeed and would be insufficient to inspire social change if it were to succeed; and, finally, my conventionalist approach is wedded to a misguided intensionalist semantics, for an extensionalist semantics is more appropriate for the term “racist.”.

In this paper, I aim to shed light on the use of transcendental deductions, within demonstrations of aspects of Wittgenstein's early semantics, metaphysics, and philosophy of mathematics. I focus on two crucial claims introduced by Wittgenstein within these transcendental deductions, each identified in conversation with Desmond Lee in 1930-31. Specifically, the claims are of the logical independence of elementary propositions, and that infinity is a number. I show how these two, crucial claims are both demonstrated and subsequently deployed by Wittgenstein (...) within a series of transcendental deductions, a series which begins with extensionalism as a generalized condition of sense on propositions, and in the context of which are then derived various, further, significant and unobvious presuppositions generated by that generalized condition of sense. In addition to clearing up deductions of these two, aforementioned claims, I also elucidate deductions of the subsistence of objects, and of logical space as an infinite totality. (shrink)

This is the first installment of a two-part essay. Limitations of space prevented the publication of the full essay in present issue of the Journal. The second installment will appear in the next issue, 2021 (1). My overall goal is to outline a strategy for integrating generative linguistics with a broadly pragmatist approach to meaning and communication. Two immensely useful guides in this venture are Robert Brandom and Paul Pietroski. Squarely in the Chomskyan tradition, Pietroski’s recent book, Conjoining Meanings, offers (...) an approach to natural-language semantics that rejects foundational assumptions widely held amongst philosophers and linguists. In particular, he argues against extensionalism—the view that meanings are (or determine) truth and satisfaction conditions. Having arrived at the same conclusion by way of Brandom’s defl ationist account of truth and reference, I’ll argue that both theorists have important contributions to make to a broader anti-extensionalist approach to language. What appears here as Part 1 of the essay is largely exegetical, laying out what I see as the core aspects of Brandom’s normative inferentialism (§1) and Pietroski’s naturalistic semantics (§2). In Part 2 (next issue), I argue that there are many convergences between these two theoretical frameworks and, contrary to first appearances, very few points of substantive disagreement between them. If the integration strategy that I propose is correct, then what appear to be sharply contrasting commitments are better seen as interrelated verbal differences that come down to different—but complementary—explanatory goals. The residual disputes are, however, stubborn. I end by discussing how to square Pietroski’s commitment to predicativism with Brandom’s argument that a predicativist language is in principle incapable of expressing ordinary conditionals.

This dissertation examines critically the assumptions of extensionalism and the traditional doctrine of substitutivity, according to which codesignativeness or coextensionality of terms should be a sufficient condition to guarantee intersubstitution of expression salva veritate. First, the discussion focuses on the traditional justifications of the extensionalist principles of substitutivity. The following alleged sources of support for extensionalism are examined: the claim that the extensionalist approach to substitutivity relies on fundamental principles outside the domain of semantics, like the Law of (...) Indiscernibility of Identicals and Leibniz's Law of Substitutivity; the assumption that all sentences that exhibit failures of substitutivity have in common a certain structure, that they include explicit or implicit intensional operators, which cause failures of substitutivity; the presumption that the extensionalist principles of substitutivity follow from a thesis of compositionality of meaning,according to which the meaning of a complex expression is determined by the meanings of its components and the mode of composition. Second, the intuitive foundations of a theory about the contributions of terms to the assertions expressed by uses of sentences are explored. I claim that this theory provides strong reasons to reject the extensionalist approach to substitutivity. (shrink)

In this work I bring a conception of language and meaning as a shared institution to bear upon rule-following scepticism, i.e., upon the sceptical problem concerning the semantic determinacy of expressions involving infinite or indefinitely large and open extensions. Such scepticism proceeds from the observation that the extensions of expressions of this kind are not uniquely determined by epistemically accessible facts, to conclude that the expressions in question are indeterminate in point of extension, and that their meaning must consist (...) in their use. ;In the first chapter of this work, I argue that rule-following considerations by themselves do not suffice to establish these conclusions, and that additional premises are needed. I consider both internalist and extensionalist schemes to supplement the sceptical argument. I find such schemes lacking in persuasive support. Chapter 2, in particular, concentrates on Kripke's well known exegesis of Wittgenstein's argument, and on the internalist requirements upon which it is based. ;In Chapter 3, I offer an externalist account of the normative aspect in rule following. On the account I give, the rule one is projecting is determined extensionally by one's position in a community in which his projections would be corrected and evaluated by other members, and from which one has acquired the rule in the first place through a chain of communication, rather than by one's own projections, taken in isolation, which constitute only a partial understanding of the rule in question. This account is not designed to refute scepticism; rather its aim is to account for the normativity of rule-following in ways which do not invoke the internalist requirement upon which rule following scepticism is based.

Meinong introduces the concept of implexive being and nonbeing to explain the metaphysics of universals, and as a contribution to the theory of reference and perception. Meinong accounts for Aristotle's doctrine of the inherence of secondary substances in primary substances in object theory terms as the implection of incomplete universals in complete existent or subsistent objects. The derivative notion of implexive so-being is developed by Meinong to advance an intuitive modal semantics that admits degrees of possibility. A set theoretical interpretation (...) of Meinong's mereological concept of the implection of incomplete beingless objects in existent or subsistent complete objects is proposed. The implications of Meinong's concept of implection are exploited to answer extensionalist objections about "Meinong's jungle", defending the ontic economy of an extraontological neo-Meinongian semantic domain that supports individual reference and true predication of constitutive properties to beingless objects.

This article examines how Quine and Sellars develop informatively contrasting responses to a fundamental tension in Carnap’s semantics ca. 1950. Quine’s philosophy could well be styled ‘Essays in Radical Empiricism’; his assay of radical empiricism is invaluable for what it reveals about the inherent limits of empiricism. Careful examination shows that Quine’s criticism of Carnap’s semantics in ‘Two Dogmas of Empiricism’ fails, that at its core Quine’s semantics is for two key reasons incoherent and that his hallmark Thesis of (...) class='Hi'>Extensionalism is untenable. The tension in Carnap’s semantics together with Quine’s exposure of the severe limits of radical empiricism illuminate central features of Sellars’s philosophy: the fully general form of the myth of givenness, together with Sellars’s alternative Kantian characterisation of understanding; the full significance of Carnap’s distinction between conceptual analysis and conceptual explication, and its important methodological implications; the specifically pragmatic character of Sellars’s realism; and Sellars’s methodological reasons for holding that philosophy must be systematic and that systematic philosophy must be deeply historically and textually informed. This paper thus re-examines this recent episode of philosophical history for its philosophical benefits and systematic insights. (shrink)

1. What's in a Name?Can philosophy of language do without the concept of intentionality? To approach this important question it may be useful to begin with the minimal explanatory requirements for a theory of reference that tries to explain the naming of objects as the simplest linguistic act. The limitations of trying to understand meaning without intentionality are therefore best illustrated by considering what is generally acknowledged to be the most thorough-going attempt to dispense altogether with intentional concepts in Frege's (...) reputedly purely extensionalist semantics of proper names. I shall argue that despite his avowed anti-psychologism, Frege paradoxically needs to include psychological elements alongside his famous distinction between sense and reference in order to preserve the universal intersubstitutability of singular referring expressions salva veritate as an adequate extensional criterion of coreferentiality. In so doing, a revisionary Fregean semantics introduces the first instalment of intentionality at the foundations of naming, by which intentionality pervades the philosophy of language. (shrink)

In this paper we argue that there is a large class of expressions, typified by ‘plastic flower’, ‘stuffed animal’ and ‘kosher bacon’, that have a unique semantics combining compositional, idiomatic and decompositional interpretation. These expressions are compositional because their constituents contribute their meanings to the meanings of the wholes; they are idiomatic because their interpretation involves assigning dictionary entries to non-terminal elements in their syntactic structure; and they are decompositional because their meanings have proper parts that are not the meanings (...) of any of their syntactic constituents. We argue that extensionalist semantics, on which the meaning of an expression is a function from domains to extensions in those domains, cannot provide an adequate account of the semantics of these expressions, and that supplementation with a theory of pragmatic interpretation does not improve the situation. We show how our account explains the intensionality and the productivity of these expressions. (shrink)

The major goal of this paper is to argue that a well known argument to overturn the principle that coextensive predicates substitute in any statement without alteration of truth value can be avoided - even in the simplest of languages. Apparently this can be done nonartificially only by expanding the universe with nonexisting objects. It is not proved that the principle of substitution salva veritate holds in Meinongian model structures, but in fact it does - as any completeness proof of (...) free logics based on inner domain-outer domain semantics will show. I f - as some have suggested - Meinong's views are compatible with the attitudes of a complete extensionalist, and he subscribed to the outlined modern theory of predication, there is no escape from Außersein. That may seem terribly obvious, but in the light of the development of free logics, more than mere conviction is needed. This dogmatic intuition is supplanted with some strong inclining reasons.

This paper offers an interpretation of Quine's naturalized epistemology through the lens of Jaegwon Kim's influential critique of the same. Kim argues that Quine forces a false choice between traditional deductivist foundationalism and naturalized epistemology and contends that there are viable alternative epistemological projects. However it is suggested that Quine would reject these alternatives by reference to the same fundamental principles (underdetermination, indeterminacy of translation, extensionalism) that led him to reject traditional epistemology and propose naturalism as an alternative. Given (...) this interpretation of Quine, it is essential that a successful critic of naturalism also examine Quine's aforementioned principles. The divide between naturalist and nonnaturalist epistemology turns out to be defined by the divide between more fundamental naturalist and nonnaturalist approaches to semantics. (shrink)

The development and changes in Quine's ideas on universais are analysed, and especially the interplay of the notions of attribute, set and predicate is highlighted. In a first logico-mathematical part it is shown how Quine banned attributes as a result of extensionalism, and how set-theoretic solutions for Russell's paradox disturbed the easy view of each predicate determining a class. Quine even tried to formulate nominalistic theories without universais (sets). It is further shown how linguistic considerations played a role in (...) Quine's ideas on universais. The role of predicates is scrutinised, and it is shown how they are torn between logical and linguistic demands. It is suggested that the role of attributes has been taken over by predicates. This semantic role of predicates is quite unstable. I conclude with the suggestion that Quine should separate set theory and linguistics more radically. (shrink)

Philosophers of language have drawn on metamathematical results in varied ways. Extensionalist philosophers have been particularly impressed with two, not unrelated, facts: the existence, due to Frege/Tarski, of a certain sort of semantics, and the seeming absence of intensional contexts from mathematical discourse. The philosophical import of these facts is at best murky. Extensionalists will emphasize the success and clarity of the model theoretic semantics; others will emphasize the relative poverty of the mathematical idiom; still others will question the aptness (...) of the standard extensional semantics for mathematics. In this paper I investigate some implications of the Gödel Second Incompleteness Theorem for these positions. I argue that the realm of mathematics, proof theory in particular, has been a breeding ground for intensionality and that satisfactory intensional semantic theories are implicit in certain rigorous technical accounts.

This paper re-addresses Quine's indeterminacy of translation/inscrutability of reference thesis, as a problem for cognitive theories of content. In contradistinction with Quine's behavioristic semantics, theories of meaning, or content, in the cognitivist tradition endorse intentional realism, and are prone to be unsympathetic to Quine's thesis. Yet, despite this fundamental difference, I argue that they are just as vulnerable to the indeterminacy. I then argue that the vulnerability is rooted in a theoretical commitment tacitly shared with Quine, namely, the commitment to (...) the view that the perceptual input to the cognitive system is extensional - differentiating objects, but not the aspects (or, properties) they manifest. Thus, input extensionalism, and not behaviorism, is what forces the indeterminacy. I conclude by suggesting that the solution to Quine's indeterminacy problem hinges on the elaboration of an intensional theory of perceptual input, and of content in general. (shrink)

The idea of conceptual schemes is one of the most influential and widely used notions in contemporary philosophy. Within the analytic tradition the idea occupies a fundamental position in positivist views as well as in replacing them post-positivist conceptions. Outside the analytic tradition a similar idea is of key importance in structuralist and post-structuralist theories. Despite the broad applicability of the notion of a conceptual scheme, its precise sense is far from being evident in the context of various philosophical trends. (...) Moreover, the well-known American philosopher Donald Davidson's position is that any clear, non-metaphorical meaning cannot be as - cribed to that notion at all – the statement which he tried to substantiate in his famous paper On the Very Idea of a Conceptual Scheme published in 1974.The present paper is aimed, firstly, at outlining the historico-philosophical evolution of the idea of conceptual scheme, concentrating on its development in logical positivism and post-positivist theories of such philosophers as Quine, Sellars, Kuhn, et al., and, secondly, at examining Davidson's criticism of both the idea and the position of conceptual relativism which was raised on its ground, revealing the assumptions which that criticism relies on and which concern relations between language and thought, truth and translation, as well as the role of the scheme-content dualism for empiricism and the place of extensionalism in semantics, etc. Our purpose, on the one hand, is to evaluate the historico-philosophical significance of Davidson's criticism; on the other hand, it is to show that his critical arguments remain to be actual since they shed a new light on the idea of conceptual schemes and allow us to determine their place in tackling the fundamental philosophical question of a relation between reality, thought and language.

This is a clearly written account of Martin's views of analytic truth, containing, in addition to the philosophical considerations, some novel formal results. The formal theory offered is shown to satisfy plausible adequacy conditions, and is notable for economy of assumptions--a reflection of Martin's conviction that semantical metalanguages should, so far as possible, be neutral to issues in ontology. But one need not share the author's extensionalist outlook in order to find much of interest here.--A. R. A.

The assumption that it is possible to distinguish pure syntax from any semantic interpretation is common to contemporary extensionalist approaches to philosophy of language, mind, cognitive science, and artificial intelligence. The origin of the term 'pure syntax' is traced to Carnap's distinction between pure and applied syntax and semantics, and to formalist analyses of mathematical systems as uninterpreted token manipulating games. It is argued in opposition to this trend that syntax can never be purified entirely of semantics, that there (...) can be no such thing as meaningless syntactical tokens or uninterpreted symbols, but that tokens must always betoken and symbols always symbolize something. The implications of the myth of pure syntax in rule-structured and connectionist artificial intelligence, semantic network processing, and their philosophical-psychological rationales, are explored. The fact that rule-structured artificial intelligence in principle can simulate any connectionist model, and that rule-structured artificial intelligence presupposes the myth of pure syntax links the myth to traditional approaches and new paradigms in cognitive engineering.

The division of the problems about Meaning in an extensional and an intensional theory was accused of unnecessarily duplicating the theoretical problems involved in the knowledge of Meaning. The result was either 1. an aggressive rejection of the intensional part of the problem or 2. the adoption of non-classical semantics to account for intensions. This paper suggests a reading of Frege's theory of Meaning that preserves the contribution of the intensional aspect of the question without sacrificing the benefits of the (...) classical insights. For this, however, we need to expand his theory to cases of semantic values which are not directly assertive, that is, what Micheal Dummett called ingredient value. This solution preserves the direct and intuitive insights of classical semantics, expanding it to cases where the designation of truth or falsehood does not have a unified interpretation: speculative, modal, ambiguous, relative cases or cases in which theories disputing Meaning is not straightforwardly mapped to the truth or the not-truth. The paper is a contribution to support the pragmatic interpretation of Frege's legacy by Micheal Dummett. (shrink)

It is common in philosophy of language to recognise two different kinds of linguistic meaning: literal or conventional meaning, on the one hand, versus communicated or conveyed meaning, on the other. However, once we recognise these two types of meaning, crucial questions immediately emerge; for instance, exactly which meanings should we treat as the literal (semantic) ones, and exactly which appeals to a context of utterance yield communicated (pragmatic), as opposed to semantic, content? It is these questions and, (...) specifically, how we should model the relationship between semantic content and utterance context, that is the topic of this chapter. We explore five contemporary answers to this modelling question, considering the benefits and challenges of each, before closing by examining some potential new directions for debates in this area.

When the stored representation of the meaning of a stimulus is accessed through the processing of a sensory input it is maintained in an activated state for a certain amount of time that allows for further processing. This semantic activation is generally accompanied by conscious identification, which can be demonstrated by the ability of a person to perform discriminations on the basis of the meaning of the stimulus. The idea that a sensory input can give rise to semantic (...) activation without concomitant conscious identification was the central thesis of the controversial research in subliminal perception. Recently, new claims for the existence of such phenomena have arisen from studies in dichotic listening, parafoveal vision, and visual pattern masking. Because of the fundamental role played by these types of experiments in cognitive psychology, the new assertions have raised widespread interest. (shrink)

What are the semantic representations that underlie language production? We use structural priming to distinguish between two competing theories. Thematic roles define semantic structure in terms of atomic units that specify event participants and are ordered with respect to each other through a hierarchy of roles. Event structures instead instantiate semantic structure as embedded sub‐predicates that impose an order on verbal arguments based on their relative positioning in these embeddings. Across two experiments, we found that priming for (...) datives depended on the degree of overlap in event structures. Specifically, while all dative structures showed priming, due to common syntax, there was a boost for compositional datives priming other compositional datives. Here, the two syntactic forms have distinct event structures. In contrast, there was no boost in priming for dative light verbs, where the two forms map onto a single event representation. On the thematic roles hypothesis, we would have expected a similar degree of priming for the two cases. Thus, our results support event structural approaches to semantic representation and not thematic roles. (shrink)

In virtue of what does a sign have meaning? This is the question raised by Wittgenstein's rule-following considerations. Semantic dispositionalism is a (type of) theory that purports to answer this question. The present paper argues that semantic dispositionalism faces a heretofore unnoticed problem, one that ultimately comes down to its reliance on unanalyzed notions of repeated types of signs. In the context of responding to the rule-following paradox—and offering a putative solution to it—this amounts to simply assuming a (...) solution to the problem in one domain and using it to solve the same problem in another. Given, moreover, the level at which the rule-following paradox undercuts dispositionalism—the level of the notion of a sign's repetition—the objections made to the view also rule out causal/informational theories of meaning as well as communitarian/assertion-theoretic ones as potential solutions to the rule-following paradox.

In the pair of articles of which this is the second, I present a set of problems and philosophical proposals that have in recent years been associated with the term “relativism”. These problems are related to the question of how we should represent thought and speech about certain topics. The main issue is whether we should model such mental states or linguistic acts as involving representational contents that are absolutely correct or incorrect, or whether, alternatively, their correctness should be thought (...) of as varying with some (more or less surprising) factor. In the first article, “Relativism 1: Representational Content”, I discussed the general issue of relativism about representational content. I argued for the conciliatory view that both relativist and absoutist conceptions of representational content can be legitimate. In the present continuation, I look in more detail at a special case of the general issue, namely the question of whether semantic contents, i.e. the contents assigned to linguistic utterances in the semantics of natural language, should be construed in an absolutist or in a relativist way.

From ethics to epistemology to metaphysics, it is common for philosophers to appeal to “intuitions” about cases to identify counterexamples to one view and to find support for another. It would be interesting to examine the evidential status of such intuitions, snap judgments, gut reactions, or whatever you want to call them, but in this paper I will not be talking about moral, epistemological, or metaphysical intuitions. I’ll be focusing on semantic ones. In fact, I’ll be focusing on (...) class='Hi'>semantic intuitions about sentences, not individual words (although the contributions of individual words may ultimately be at issue in some of these cases), and on closely related intuitions about what is said in utterances of those sentences. Such intuitions play an important role in philosophy of language.. (shrink)

This book grew out of my confusion. If logic is objective how can there be so many logics? Is there one right logic, or many right ones? Is there some underlying unity that connects them? What is the significance of the mathematical theorems about logic which I've learned if they have no connection to our everyday reasoning? The answers I propose revolve around the perception that what one pays attention to in reasoning determines which logic is appropriate. The act of (...) abstracting from our reasoning in our usual language is the stepping stone from reasoned argument to logic. We cannot take this step alone, for we reason together: logic is reasoning which has some objective value. For you to understand my answers, or perhaps better, conjectures, I have retraced my steps: from the concrete to the abstract, from examples, to general theory, to further confirming examples, to reflections on the significance of the work.
