Buzaglo (as well as Manders (J Philos LXXXVI(10):553–562, 1989)) shows the way in which it is rational even for a realist to consider ‘development of concepts’, and documents the theory by numerous examples from the area of mathematics. A natural question arises: in which way can the phenomenon of expanding mathematical concepts influence empirical concepts? But at the same time a more general question can be formulated: in which way do the mathematical concepts influence empirical concepts? What I (...) want to show in the present paper can be described as follows. The problem articulated by Buzaglo deserves some semantic refinements. Following explications are needed: What is meaning? (In particular: What are concepts?) What are questions? (Or, equivalently: Semantics of interrogative sentences.) -/- Further, a useful notion will be the notion of problem. Taking over the notion of conceptual system from Materna (Conceptual Systems. Logos, Berlin, 2004) and using Tichý’s Transparent intensional logic (TIL) I can try to solve the problem of the relation between mathematical and empirical concepts (not only for the case of expanding some mathematical concepts).

According to a widespread view, Einstein’s definition of time in his special relativity is founded on the positivist verification principle. The present paper challenges this received outlook. It shall be argued that Einstein’s position on the concept of time, to wit, simultaneity, is best understood as a mitigated version of concept empiricism. He contrasts his position to Newton’s absolutist and Kant’s transcendental arguments, and in part sides with Hume’s and Mach’s empiricist arguments. Nevertheless, Einstein worked out a concept empiricism that (...) is considerably more moderate than what we find in the preceding empiricist tradition and early logical positivism. He did not think that the origin of concepts is in observations, but in conventions, and he also maintained a realist ontology of physical events, which he thought is necessary for his theory. Consequently, his philosophy of time in special relativity is not couched in terms of an anti-metaphysical verificationism. (shrink)

This article presents the evolution of philosophical and methodological considerations concerning empiricism in computer/computing science. In this study, we trace the most important current events in the history of reflection on computing. The forerunners of Artificial Intelligence H.A. Simon and A. Newell in their paper Computer Science As Empirical Inquiry started these considerations. Later the concept of empirical computer science was developed by S.S. Shapiro, P. Wegner, A.H. Eden and P.J. Denning. They showed various empirical aspects of (...) computing. This led to a view of the science of computing - the science of general scope. Some interesting contemporary ways towards a generalized perspective on computations were also shown. (shrink)

Carnap’s search for a criterion of empirical significance is usually considered a failure. I argue that the results from two out of his three different approaches are at the very least problematic, but that one approach led to success. Carnap’s criterion of translatability into logical syntax is too vague to allow for definite results. His criteria for terms—introducibility by chains of reduction sentences and his criterion from “The Methodological Character of Theoretical Concepts”—are almost trivial and have no clear relation (...) to the empirical significance of sentences. However, his criteria for sentences—translatability, verifiability, falsifiability, confirmability—are usable, and under the assumptions needed for the Carnap sentence approach, verifiability, falsifiability, and translatability become equivalent. As a result of the Carnap sentence approach, metaphysics is rendered analytic. (shrink)

Redpilled is a term with which online communities from the reactionary spectrum identify their political position: although they can be grouped within the spectrum of the extreme right, studies of these spaces highlight their heterogeneous and undefined character. This paper aims to contribute to the study of these online communities by considering them as spaces for the construction and resignification of concepts for ideological confrontation. To this end, we will argue that they constitute discursive communities that use language to achieve (...) ideological objectives, and that the Kantian doctrine of schematism can help to explain how such language maintains its coherence despite the heterogeneity of the group and the imprecise nature of the concepts that are used.

Merely conceptual knowledge, not based on specific sensitivity to the referential domain, is not seriously a priori. It is argued here that it is either weakly and superficially a priori, or downright a posteriori. This is done starting from the fact that many of our definitions (or concepts) are recognizably empirically established, and pointing out that recognizably empirical grounding yields superficial apriority. Further, some (first-order) concept analyzing propositions are empirically false about their referents and thus empirically refutable. Therefore, our (...) empirical definitions (or concepts) are fallible and empirically revisable: they can turn out to be incorrect about the intended satisfiers of the concept defined, and their concept analyzing propositions to be false. Now, empirical revisability is incompatible with strong apriority (and entails at best a weak apriority or aposteriority). The result is quite shocking: analyticity does not entail apriority.

Philosophy traditionally deals with such lexicalized concepts as WISDOM, VIRTUE, REASON, WORLD VIEW, INFINITE UNIVERSE, and PHILOSOPHY. They trigger interest in philosophy, particularly because they are difficult to understand and explain. It is all the more surprising that many contemporary philosophers focus on such concepts as DOG, CHAIR, and FLIGHT to build their theories and provide examples. The article argues that to preserve topical equilibrium and avoid methodological problems, both classes of concepts should be involved in philosophical theorization and exemplification. (...) The first part critically discusses attempts at identifying these classes as ordinary vs. big (Gauker), empirical vs. pure (Kant), and concrete vs. abstract (contemporary psycholinguistics). It introduces the opposite pair simple empirical vs. complex demanding concepts as an alternative heuristic tool to evaluate concepts. The second part elaborates on the concept of concept and structural similarities between the two classes of concepts in semantic and ‘onomantic’ perspectives. The third part shows that despite structural similarities, such factors as the availability of empirical data, identification of the referent, historical and theoretical loadedness, complexity, and demandingness indicate that simple empirical and complex demanding concepts should be addressed in different ways. The final part elaborates on the notion of topical equilibrium as a philosophical method and norm and discusses two further examples (COW and ARTHRITIS) from contemporary debates in conceptual engineering.

In this book I have tried to develop an analysis of the concept of an empirical law, an analysis that differs in many ways from the alternative analyse's found in contemporary literature dealing with the subject. 1 am referring especially to two well-known views, viz. the regularity and necessity views, which have given rise to many interesting papers and books within the philosophy of science. In developing my own views, it very soon became clear to me that the mere (...) restatement of these alternative views, followed by a discussion of their defects and an explanation of my own view, would not suffice to show what 1 regard as basically unsound in these views. If we seriously consider the well-known difficulties facing the regularity view, we have to consider the possibility that the time has arrived to stop our attempts to solve, by means of patch-work additions, the fundamental problem of empirical laws within the traditional context of logical positivist doctrines. I have tried to find a solution which is based on a different philosophical context, the main incentive being that the discouraging results of the customary attempts to solve the problem might have been the outcome of the fundamental philosophical setting within which the problem had been formulated and within which everyone looked for a solution. The problem of empirical laws is not a problem existing by its own rights - it is shaped by an underlying point of view or theoretical framework. For this reason I have started with a brief sketch of the logical positivist context. However, I want to stress the fact that my intention was not to offer an historical exposition, but an exposition which becomes meaningful when related to the subsequent arguments concerning empirical laws. The notion of direct or theory-free observation has been taken as the fundamental characteristic of the logical positivist point of view. This view has been further characterised by means of five theses, among which is the thesis that observational terms are isolated or theory-independent units of extensional meaning. These terms are then supposed to be the starting-points of meaning and the end-points of confirmation, and these very characteristics mark the privileged position such terms have in a logical positivist philosophy. The post-positivist view, on the other hand, is characterised by the opposing notion of theory-loaded observation. This notion leads to other conclusions which radically oppose some of the theses of logical positivism. The notion of theory- loaded observation itself, although often clearly stated, has not yet been systematically elucidated, and I have made an attempt to do this in ch. I after my sketch of the logical positivist context. This seemed to me to be necessary in order to make my post-positivist point of view as clear as possible, before tackling the problem of empirical law itself. I have paid special attention to the lawlikeness of concepts and their confirmation and falsification. These epistemological issues are followed by a separate examination of Goodman's riddle in ch. II, because it lies somewhere between the lawlikeness of concepts and the lawlikeness of laws. If Goodman's riddle is taken as a serious problem, as I think it should, it is primarily a problem of concept or theory formation and not a problem of induction. In ch. III the regularity view has been examined and the well-known difficulties related to such a view are considered, assuming the knowledge gained in ch. I. This has led to some interesting results, especially in connection with the analysis of counterfactuals and the confirmation of 'normal' singular conditionals, to which I return in the last chapter. Three different views of the necessity view are briefly stated and investigated in ch. IV. RESCHER'S view is, I think, close to mine, which has been developed in ch. V. However, there are fundamental epistemological differences between our views. In the last chapter I have given my own analysis of the concept of an empirical law, which should not be taken as a synthesis of a regularity and a necessity view, but as opposed to both. It is, as far as particulars may count, the result of an analysis of the concepts 'regularity' and 'necessity'. I have tried to argue that the greatest shortcoming of the regularity view lies in the fact that the proponents of such a view have not been really concerned with the concept of 'regularity' itself. They usually take this concept to be intuitively clear enough to serve as basis for their analysis. Their attacks upon the necessity view are based on the reproach that 'necessity' is a very obscure concept, and that it should, therefore, be avoided in the philosophy of science. We could, however, reproach them in a similar way, since the concept of 'regularity' is anything but clear. One may say that an empirical law formulates a 'regularity in nature', but we can only do justice to the function a law has in science, if we are ready to view this regularity as a necessary connection, which does not exist in an observer-independent reality, but in a theoretically co-constituted empirical world. This investigation does not pretend to answer all questions concerning empirical laws. It should, therefore, not be regarded as complete, but neither should the arguments and suggestions be regarded as completely free from ambiguity. Much remains to be done in order to offer a generally acceptable theory and better understanding. (shrink)

This article presents a detailed, novel account of the emergence of (the meaning of) empirical concepts. Acquiring experience and empirical concepts is shown to be the result of multifaceted, cognitive processes, which require both material realization and conceptual interpretation. Generally speaking, the meaning of empirical concepts consists of several distinct components, but it includes at least a structuring and an abstracting component. These two meaning components are abstract entities, which can be justifiably interpreted as real objects.On this (...) basis, I address the subject of emergence. The primary claim is that the abstracting meaning component (but not the structuring one) emerges from its underlying empirical processes: it both depends on and transcends these processes. This claim is expounded by discussing relevant similarities and dissimilarities between the emergence of abstract meanings and a range of central features of emergence prominent in recent debates on this topic. The conception of empirical concepts with emergent abstracting meaning components involves an interpretation that avoids the problematic extremes of both empiricism and Platonism. (shrink)

Economists use a variety of normative empirical concepts because the economy and morality are intertwined. Often, this normativity is intended and widely acknowledged, signaling the relevance and meaning of research. Sometimes, the objectivity of research and the findings obtained by using normative concepts is problematic. Written from the perspective of a practicing economist, the article offers a practical guiding tool to economists, suggesting how to be responsible in developing and using normative empirical concepts. It is based on valuable (...) insights from the philosophy of science and codes of conduct. It illustrates the use of the guiding tool with the example of a normative empirical concept that is widely used in development economics: ‘ethnic fractionalization’. The conclusion is that applied economists should be more involved in being accountable for the normativity in our work and that we should ensure that, by using the tool, the normative concepts that we use are acceptable.

The title of this symposium, “Formal Simplicity as a Weight in the Acceptability of Scientific Theories,” to some people might seem to suggest that we are to be making positive proposals about how the concept of simplicity could be defined for formalized languages, defined so as to figure in a formalized theory of confirmation. I must confess at the start that I do not have any such ambitious object in view. I now feel, indeed, that premature formalizations have little power (...) to illuminate the philosophically interesting questions which cluster round the problem of the role of simplicity in scientific thinking. So in this short paper I wish merely to present some elementary considerations, not very novel ones, concerning the role which simplicity seems to me to play in our non-demonstrative reasoning about matters of empirical fact. Although many writers have sought to analyze the logical character of such reasoning, little unanimity has been attained in their over-all views; thus it is that though the considerations which I wish to present are elementary, they are not wholly uncontroversial. But because these matters are elementary in nature, I do feel it appropriate in discussing them to use homely examples of uncomplicated kinds, rather than elaborate examples drawn from the more sophisticated reaches of scientific theory; in doing so, I am taking it for granted that scientific inference as regards its logical character is fundamentally a refinement of everyday thinking, rather than a procedure of some essentially different nature.

The problem of concept representation is relevant for many sub-fields of cognitive research, including psychology and philosophy, as well as artificial intelligence. In particular, in recent years it has received a great deal of attention within the field of knowledge representation, due to its relevance for both knowledge engineering as well as ontology-based technologies. However, the notion of a concept itself turns out to be highly disputed and problematic. In our opinion, one of the causes of this state of affairs (...) is that the notion of a concept is, to some extent, heterogeneous, and encompasses different cognitive phenomena. This results in a strain between conflicting requirements, such as compositionality, on the one hand and the need to represent prototypical information on the other. In some ways artificial intelligence research shows traces of this situation. In this paper, we propose an analysis of this current state of affairs. Since it is our opinion that a mature methodology with which to approach knowledge representation and knowledge engineering should also take advantage of the empirical results of cognitive psychology concerning human abilities, we outline some proposals for concept representation in formal ontologies, which take into account suggestions from psychological research. Our basic assumption is that knowledge representation systems whose design takes into account evidence from experimental psychology may therefore give better results in many applications. (shrink)

If concepts are explicated as abstract procedures, then we can easily show that each empirical concept is a not an effective procedure. Some, but not all empirical concepts are shown to be of a special kind: they cannot in principle guarantee that the object they identify satisfies the intended conditions.

A concept is traditionally defined via the necessary and sufficient conditions that clearly determine its extension. By contrast, cognitive views of concepts intend to account for empirical data that show that categorisation under a concept presents typicality effects and a certain degree of indeterminacy. We propose a formal language to compactly represent concepts by leveraging on weighted logical formulas. In this way, we can model the possible synergies among the qualities that are relevant for categorising an object under a (...) concept. We show that our proposal can account for a number of views of concepts such as the prototype theory and the exemplar theory. Moreover, we show how the proposed model can overcome some limitations of cognitive views. (shrink)

Although Kant is most well-known for his arguments in support of pure or a priori concepts, he also attempts to give an account of how empirical concepts are acquired. In this paper I want to take a close look at this account. Specifically, I am interested in a recent criticism that Kant’s explanation of empirical concept acquisition is, in some sense, circular. I will consider and criticize a recent attempt to solve this problem. Finally, I will argue for (...) my own solution to the circularity problem relying, oddly enough, on Kant’s commitment to pure or a priori concepts of the understanding as well as the pure forms of the imagination. Briefly, I want to argue that Kant can give a coherent and non-circular account of empirical concept acquisition relying primarily on the a priori conceptual tools developed in the Critique of Pure Reason.

Concept formation has recently become a widely discussed topic in philosophy under the headings of “conceptual engineering”, “conceptual ethics”, and “ameliorative analysis”. Much of this work has been inspired either by the method of explication or by ameliorative projects. In the former case, concept formation is usually seen as a tool of the sciences, of formal disciplines, and of philosophy. In the latter case, concept formation is seen as a tool in the service of social progress. While recent philosophical discussions (...) on concept formation have addressed natural sciences such as physics as well as various life sciences, so far there is only little direct engagement with the social sciences. To address this shortcoming is important because many debates about socially relevant concepts such as power, gender, democracy, risk, justice, or rationality, may best be understood as engaging in conceptual engineering. This topical collection addresses the nature and structure of concept formation in the natural, the life, and the social sciences alike, both as a process taking place within science and as an activity that aims at a broader impact in society. This helps to understand how concept formation proceeds not only in the natural sciences but also in disciplines such as psychology, cognitive science, political science, sociology and economics.

In lieu of an abstract, here is a brief excerpt of the content:New Rhetoric's Empire:Pragmatism, Dogmatism, and SophismRomain LauferPragmatism vs. RationalismThere are at least two reasons to devote some attention to sophism when dealing with the relationship between philosophy and rhetoric in the context of Franco-American intellectual exchanges. The first reason is that it lies at the very origin of classical philosophy which could be described as resulting directly from the way in which Plato and Aristotle succeeded in separating the (...) realm of rhetoric from the realm of philosophy. The second reason arises out of the way in which Durkheim, the founder of French academic sociology, thought it necessary to establish a clear distinction between sociology and pragmatism. This was done in a course given at the Sorbonne during the academic year 1913–14. The course could be considered a direct answer to the lectures on pragmatism given by William James at the Lowell Institute in Boston in 1906–7 (Durkheim 1955).From the very beginning of his talk, Durkheim expresses an extremely ambivalent point of view. On the one hand, pragmatism, better than any other doctrine, allows one to feel the necessity of reforming or renovating the type of "traditional rationalism" that dominated the French intellectual atmosphere of the time. On the other hand, it represents a real threat for this same rationalist tradition. Is it not a declaration of war that pragmatism launches on rationalism when William James writes that "against [End Page 326] rationalism as a pretension and a method pragmatism is fully armed and militant" (1975, 32)? In the face of this attack Durkheim declares that what is at stake are the very foundations of French culture: "Our whole French culture is essentially based on rationalism. Here the eighteenth century lives on. Thus, a radical negation of rationalism would constitute a danger: it would imply a complete disruption of our national culture. The whole French spirit would have to be transformed if the form of irrationalism that pragmatism represents were to be admitted" (1955, 28). Durkheim adds that this threat is not limited to the French tradition: "Not only our culture but the whole of the philosophical tradition has been, since the very beginnings of philosophical speculation—apart from a single exception that will be dealt with later—of a rationalist tendency. Therefore it is toward the disruption of all this tradition that one would have to proceed if pragmatism were valid" (1955, 28).Durkheim insists that what pragmatism tends to destroy is the "cult of truth," the fact that there are judgments that are necessary, which he will allude to throughout his analysis as corresponding to a dogmatic conception of truth that is repeatedly criticized by William James. James writes in his lectures on pragmatism that "rationalism is comfortable only in the presence of abstractions[;]... objective truth must be something non-utilitarian, haughty, refined, remote, august, exalted. It must be the absolute correspondence of our thoughts with an equally absolute reality.... Down with psychology, up with logic, in all this question!" (1975, 38).This allows Durkheim to declare that by stating that the human mind is free in front of the truth, pragmatism approaches the single exception he mentioned, namely, sophism, which in a similar manner negated truth. This connection is not arbitrary: it is avowed by the pragmatists themselves (1955, 28–29). Thus F. C. S. Schiller proclaims himself a "Protagorean" and recalls the axiom that "man is the measure of all things."Thus the debate between rationalism and pragmatism—between, according to Durkheim, a French philosophical tradition characterized by its link with a Cartesian dogmatic form of rationalism and an American philosophy characterized by its link with pragmatism—can be seen as the continuation of the debate between Plato and Aristotle, on the one hand, and the Sophists, on the other, at the origin of Western philosophy. Moreover, Durkheim tells us that the resurgence of the debate between pragmatism and philosophy corresponds to a historical transformation that affects the whole Western world. Pragmatism is becoming the only and dominant philosophy of the time. The central trait of this intellectual orientation is its [End Page 327] focus on action, a focus it shares with sociology itself: both are "daughters of... (shrink)

Jerry Fodor’s arguments against the possibility of concept learning, and the responses that have been offered in defense of the coherence of concept learning, have both by and large assumed that concept learning is a descriptive process. I offer an alternative, ostensive approach to concept learning and explain how descriptive concept learning can be explained as a version of ostensive concept learning. I argue that an ostensive view of concept learning offers an empirically plausible and philosophically adequate account of concept (...) learning that is explanatorily superior to traditional descriptive views.

My paper sets out to demonstrate that Weber's ideal-typical theory of concept formation, subject to certain modifications, is compatible with the principles of philosophical hermeneutics and is therefore a valuable strategy of concept formation for interpretive historical inquiry. The essay begins with a brief recapitulation of the philosophical-hermeneutic approach to the human sciences. I then chart out the affinities as well as the discrepancies between philosophical hermeneutics and Weber's theory of the ideal type. Against this backdrop, I proceed to offer (...) a number of correctives and additions to Weber's theory so as to tighten its fit with philosophical hermeneutics. First, I argue that the ideal type's proper logic of concept formation is a logic of significance rather than a logic of commonality. Second, I claim that the relationship between the various empirical cases to which a given ideal type is (or can be) applied is a Wittgensteinian relationship of family resemblance. Finally, I present two main kinds of epistemological functions that ideal types can fulfill within the framework of historical inquiry: argumentative and orientational-clarificatory. (shrink)

With the discovery of consistent non-Euclidean geometries, the a priori status of Euclidean proof was radically undermined. In response, philosophers proposed two revisionary interpretations of the practice: some argued that Euclidean proof is a purely formal system of deductive logic; others suggested that Euclidean reasoning is empirical, employing concepts derived from experience. I argue that both interpretations fail to capture the true nature of our geometrical thought. Euclidean proof is not a system of pure logic, but one (...) in which our grasp of the content of geometrical concepts plays a central role; moreover, our grasp of this content is a priori. (shrink)

This paper reviews Deleuze’s theory of language in Logic of Sense, and Deleuze and Guattari’s theory of language in A Thousand Plateaus. In the ontology informed by the Stoics described in those books, human being and language do not exist separately but in a mixture of words and things. The author argues that this flattened ontology of surfaces is incommensurable with the ontology of depth used in conventional humanist qualitative methodology and recommends beginning new empirical inquiry with a (...) concept instead of with method and methodology.

In the Tractatus 4.126 Wittgenstein introduces the notion of a formal concept which, he says, needs to be distinguished from the notion of a proper concept, i.e. a concept such as that of “man” which has an ordinary empirical application. The sense in which formal concepts are formal is not that they have anything in particular to do with formal logic or logical form, but that they are concerned with what Wittgenstein called the “form of representation”. That is (...) to say that they are concerned with the ways in which expressions can represent the world. To put it in another way, they are concerned with the use or application to which expressions might be put. Now, it is well known that for the Wittgenstein of the Tractatus it was impossible to say anything about the form of representation of any expression: this could only be shown. Hence Wittgenstein calls these formal concepts “pseudo–concepts”, meaning by this not that there are not such concepts, but that they are incompatible with his theory. (shrink)

RésuméIl n'y a pas de sujet plus idoine à justifier la philosophie ouverte qui est celle de Dialectica que l'étude de l'évolution du concept de raison dans la pensée occidentale.C'est avec la création de la géométrie déductive que le mot raison prit un sens chez les Grecs du ***Ve siècle av. J.‐C. A l'évidence sensible qui résulte du témoignage de nos sens et ne constate que le comment d'un fait observé, les géomètres grecs substituent l'évidence intelligible qui en explique le (...) pourquoi, en montrant qu'il est la conséquence nécessaire d'un petit nombre de propositions admises comme évidentes. S'élevant du concret à l'abstrait, ils dégagent l'essence intelligible de l'accident sensible et substituent au réel le possible. Les disciplines empiriques des Orientaux font place aux sciences théoriques et explicatives: l'astronomie, la mécanique, l'optique, la théorie musicale. Toutefois, au lieu de voir dans les concepts mathématiques une création de l'esprit, les penseurs‐géomètres de la Grèce les assimilent à une découverte par les yeux de l'ǎme d'essences préexistantes. Ils méprisèrent, en outre, les applications pratiques qui seules peuvent stimuler les sciences expérimentales. De là procèdent les limites, puis l'arrět de la science hellénique.Les conquětes d'Alexandre déversèrent sur l'Occident méditerranéen les religions de salut de l'Orient. A la recherche désintéressée du vrai se substitue la gnose, la révélation de mystères transcendants à la raison. Lorsque le message chrétien devint une philosophie puis une théologie, on en vint à distinguer » la démonstration hellénique « par le raisonnement et la dialectique, et » la démonstration hébraique « par les prophéties et les miracles des articles de la foi. La Scolastique rechercha l'accord de la raison et de la foi, en entendant par raison l'apport de la science et de la philosophie helléniques, assimilées, à partir du XIIIe siècle dans la Latinité, à l'encyclopédie aristotélicienne. La Scolastique échoua dans cette tentative. La doctrine de » la double vérité « fut l'aveu de cette impuissance.Pour se libérer de la mentalité scolastique, il fallut s'affranchir dans l'étude des phénomènes naturels de l'autorité d'Aristote, du joug de la théologie et parvenir à une théorie correcte de la connaissance, en particulier de la valeur des idées abstraites et de la distinction des vérités formelles et des vérités empiriques. Il fallut interpréter comme une création de l'esprit ce que les Grecs assimilaient à une découverte de vérités préexistantes. La désagrégation de l'a priori synthétique, conçu à la façon des Cartésiens et des Kantiens, conduit à se demander ce qui subsiste des exigences a priori de la raison. C'est à quoi s'évertue de répondre la dernière partie de l'article.ZusammenfassungEs gibt keinen geeigneteren Gegenstand zur Rechtfertigung der offenen Philosophie, die von der Dialectica vertreten wird, als das Studium der Entwicklung des Vernunftsbegriffes im abendländischen Denken.Mit der Entstehung der deduktiven Geometrie erhält das Wort Vernunft bei den Griechen des 5. Jahrhunderts vor Christo einen Sinn. An Stelle der gefühlsmässigen Evidenz, die auf der Gewissheit unserer Sinne beruht und lediglich das Wieeiner beobachteten Tatsache feststellt, setzen die griechischen Geometer die logische Evidenz, die das Warum erklärt, indem sie zeigt, dass es eine Folge einer kleinen Zahl von Voraussetzungen ist, die als evident angesehen werden können. Sich vom Konkreten zum Abstrakten erhebend, befreien sie das intelligible Wesen von der Zufälligkeit des Sinnlichen und ersetzen das Reelle durch das Mögliche. Die empirischen Disziplinen der Morgenländer schaffen Platz für die theoretischen und erklärenden Wissenschaften wie Astronomie, Mechanik, Optik, Musiktheorie. Immerhin, anstatt in den mathematischen Konzepten eine Schöpfung des Geistes zu sehen, setzen die geometrischen Denker Griechenlands diese der Entdeckung präexistenter Essenzen durch die Augen der Seele gleich. Sie verachten im übrigen die praktischen Anwendungen, die nur die Experimentalwissen‐schaften anregen können. Daher kommt es, dass die griechische Wissenschaft bei einer gewissen Grenze Halt machen musste.Die Schlachten Alexanders verschlangen im Abendland des Mittelmeeres die Heilsreligionen des Orients. An Stelle des uneigennützigen Suchens nach der Wahrheit tritt die Gnosis, das Erheben des mysteriös‐Transzendenten in den Bereich der Vernunft. Als die christliche Botschaft eine Philosophie, darauf eine Theologie wurde, begann man zu unterscheiden zwischen der » griechischen Beweisführung « mittels Vernunft und Dialektik und der » hebräischen Beweisführung « mittels Prophezeiungen und Wundern des zu Glaubenden. Die Scholastik forschte nach dem Zusammenhang zwischen Vernunft und Glaube, indem sie unter Vernunft den Beitrag der griechischen Wissenschaft und Philosophie verstand, der Aristotelischen Enzyklopädie angeglichen in der Folgezeit des 13. Jahrhunderts im Römischen Reich. Die Scholastik scheiterte in diesem Versuch. Die Lehre der » doppelten Wahrheit « war das Geständnis dieses Unvermögens.Um sich von der scholastischen Mentalität zu befreien, hiess es sich im Studium der Naturereignisse von der Autorität des Aristoteles befreien, vom Joch der Theologie und zu einer korrekten Theorie der Erkenntnis zu gelangen, speziell des Wertes der abstrakten Ideen und der Unterscheidung zwischen formellen und empirischen Wahrheiten. Was die Griechen einer Entdeckung von präexistenten Wahrheiten gleichsetzten, musste als Schöpfung des Geistes interpretiert werden. Die Desagregation des synthetischen Apriori, aufgefasst im Sinne von Descartes und Kant, führte zur Frage, was vorhanden sei von den apriori‐Erfordernissen der Vernunft.Dies zu beantworten, bemüht sich der letzte Teil des Artikels.There is no subject more suitable to the open philosophy of Dialectica than the study of the development of the concept of reason in Western thought.The word » reason « acquired a meaning with the creation of deductive geometry by the Greeks of the Vth cent. B. C. These geometers substituted for the sensible evidence, which only establishes the » what « of an observed fact, the intelligible evidence which explains the » why « of such an observed fact, by showing that it is the necessary result of a small number of statements, accepted as self‐evident. Rising from the concrete to the abstract, the geometers isolated the intelligible essence from the sensible accident, and substituted for the real the possible. The empirical technics of the Orientals made place for the theoretical sciences of the Greeks: astronomy, mechanics, optics and musical theory. Instead, however, of seeing mathematical concepts as creations of the mind, the Greek geometers considered them as preexisting entities, discovered by the eyes of the soul. They furthermore disregarded the practical applications which alone can stimulate experimental sciences. These were the limitations and the causes of the eventual end of hellenic science.The conquests of Alexander brought to the Western Mediterranean the religions of salvation of the East. The gnose, revelation of mysteries transcending reason, took the place of the disinterested search for truth. As the Christian message became a philosophy and then a theology, the distinction came to be made between the » hellenic demonstration of the faith « by logic and dialectics, and the » hebrew demonstration « by the prophecies and the miracles. The scholastics sought to reconcile reason with faith, by defining reason as the legacy of Greek science and philosophy, identified, after the XIIIth century, with the Aristotelian Encyclopedia. They failed in this endeavour. The doctrine of the » double truth « was the admission of this failure.In order to progress beyond the scholastic outlook, it was necessary to reject the precepts of Aristotle in the study of natural phenomena, to become free of the tyranny of theology, to develop a correct theory of knowledge, especially as regards the role of abstract ideas and the distinction between formal and empirical truths. It was necessary to interpret as a creation of the mind what the Greeks considered the discovery of preexisting truths. The breakdown of the synthetic apriori of the Cartesians and the Kantians leads one to wonder what remains of the a priori requisites of reason. The last part of the article suggests an answer to this question. (shrink)

Context: Epistemologically, constructivism has reached its goals, particularly by emphasizing the idea of participatory observation, circularity, and the fact that construction is based on experience. However, rather than research, the main occupation of constructivists and second-order cyberneticians seems to lie in making the case for their epistemological idea, which has been exhausted in many aspects. Purpose: To counteract this exhaustion and an increasingly apparent lack of energy, it is argued that constructivism requires a dedicated field of research, a field where (...) it would be possible to test constructivist concepts empirically and thus go beyond mere theoretical discourse. Method: Based on a review of basic constructivist premises and a critical examination of the field of empirical phenomenological research, the article connects their respective findings. Results: The article proposes that empirical research on lived experience requires a constructivist epistemological foundation and might therefore be a logical continuation of constructivist endeavours. In such a way, both fields might benefit considerably. Not only would constructivism acquire an empirical tool for testing its ideas, such a partnership might also provide empirical phenomenology with a more suitable epistemological platform than the realism-based research framework of cognitive science (of which it has become an integral part. The possibilities and problems of introducing empirical research into constructivism are also discussed. Implications: The article presents an opportunity to re-think the role and future of constructivism. It suggests educating a new generation of constructivist researchers whose principal goal would be the attempt to study lived human experience. That could also open a path to the experimental grounding of many constructivist insights. (shrink)

Kant’s notion of common sense (Gemeinsinn) is crucial not only for his account of judgements of beauty, but also for the link he draws between the necessary conditions of such judgements and cognition in general. Contrary to existing interpretations which connect common sense to pleasure, I argue that it should be understood as the capacity to sense the harmony of the cognitive faculties through a sui generis sensation distinct from pleasure. This sensed harmony of the faculties is not only the (...) ground of judgements of beauty and the basis of pleasure in the beautiful, but is also essential, I argue, for the reflecting judgements through which we acquire empirical concepts.

Abstractvan Fraassen (The empirical stance, 2002) contrasts the empirical stance with the materialist stance. The way he describes them makes both of them attractive, and while opposed they have something in common for both stances are scientific approaches to philosophy. The difference between them reflects their differing conceptions of science itself. Empiricists emphasise fallibilism, verifiability and falsifiability, and also to some extent scepticism and tolerance of novel hypotheses. Materialists regard the theoretical picture of the world as matter in (...) motion as a true and explanatory account and insist on not taking ‘spooky’ entities or processes seriously as potential explanations of phenomena that so far lie outside the scope of successful science. The history of science shows us that both stances have been instrumental in the achievement of progress at various times. It is therefore plausible for a naturalist to suggest that science depends for its success on the dialectic between empiricism and materialism. A truly naturalist approach to philosophy ought then to synthesise them. Call the synthesized empiricist and materialist stances ‘the scientistic stance’. This paper elaborates and defends it.

Scholarship in experimental jurisprudence has reported surprising findings about various concepts of legal significance: _acting intentionally_, _causation_, _consent_, _knowledge, recklessness_, _reasonableness,_ and _law_ itself. Often, these studies examine laypeople’s ordinary concepts and draw broader conclusions about legal experts’ concepts. This Article questions such inferences, from empirical findings about ordinary concepts to conclusions about the concepts of those with legal expertise. It presents a case study concerning what it means to act _intentionally._ An experiment examines intentionality judgments across four populations (...) (N = 774): laypeople, law students, non-law students, and United States judges. Legal training affected judgments in three ways that are consistent with the acquisition of a distinctive legal concept. This case study supports the Article’s broader claim: Laypeople’s ordinary concepts are not equivalent to experts’ legal concepts. The acquisition of legal concepts is an important form of legal expertise. (shrink)

This paper concerns the issue of whether the so-called left wing of the Vienna Circle (Carnap, Neurath, Frank) can be understood as having provided the blueprint for a bipartite metatheory with a formal-logical part (the “logic of science”) supporting and being supported by a naturalistic-empirical part (the “behavioristics of science”). A claim to this effect was recently met by a counterclaim that there was indeed an attempt made to broaden Carnap’s formalist conception of philosophy by the pragmatist (...) Morris, but that this initiative failed and that Carnap showed no interest in it. To defend the original claim this paper provides an analysis of Carnap and Morris on the subject matter of pragmatics in order to show that and how Carnap adopted Morris’s proposals in so far as they agreed with bipartite metatheory conception.

The author defends the view that the notion of concept, if used in the logical (not cognitivist) tradition, should be explicated procedurally (i.e., not set-theoretically). He argues that Tichý’s Transparent Intensional Logic is an apt tool for such an explication and derives the respective definition. Some consequences of this definition concern the notions of emptiness, simple concepts, empirical concepts and algorithmic concepts.

As a result of this case study, additional questions arise. These can be cast into at least three groups. The first concerns the development of critical empiricism in the ancient world: a topic of much interest in our own century, expecially with regard to the work of the logical empiricists. Many of the same arguments are present in the ancient world and were hotly debated from the Hippocratic writers through and beyond Galen. Some of the ways in which Galen reacts (...) to Hippocratic and Aristotelian influences may, in part, be explained by Galen's own posture as a so-called Dogmatist. Both the Empirics and the Methodists offered alternative viewpoints on the place, role, and limits of observation in biomedical research. Though I have written on this relationship in the Hippocratic writers and Aristotle,44 it remains to be discussed in detailed fashion just how critical empiricism acted in Galen's evaluation of biomedical problems (aporiai). Contrasts between Galen and his predecessors might further clarify this issue both as a historical question and as it affects the construction of biological theory.The second area explores the question of how one develops comprehensive theories. In this respect Galen follows Aristotle's methodology rather closely. Both look at what theories are available to them and then systematically review the problems raised, at the same time refuting what they find inadequate. This is an effective strategy, for it permits utilizing the best features of earlier work to fashion a new whole. Indeed, Galen himself seems to attribute his use of such a methodology to his “ecletic” medical and philosophical training. Both Aristotle and Galen endeavor to employ techniques of theory integration. That is, they use aspects of theories they have already espoused to deal with new problems. This suggests the emergence of formal, logical coherence as an element in theory evaluation. The obvious drawback is that it can cause mistakes in one area to be repeated and ingrained in other areas. Such errors, because they are at the very core of an explanatory framework, may take centuries to correct. Future studies may shed light on how theory integration acts both in a positive and in a negative way.Finally, this case study offers a glimpse of how science progresses. Even though the advances in medical technology were comparatively minor, there is a great deal more sophistication in the conception theoreis of Aristotle and Galen than was present in the Hippocratic writers. Some of this (in Galen's case) had to do with increased anatomic and physiological knowledge, but most, I believe, is due to the evolution of scientific knowledge. If further work were done specifically on this question, it might document more completely how scientific knowledge on a specific topic evolves. The mode of advancement is primarily through gradual refinement of the types of questions being asked by these ancient authors, and the ramifications of their answers.Ancient theories of conception offer a fine case study in the history and philosophy of how a theory begins the develops. I have tried to suggest some interrelationships among the more important theories, as they focused upon Aristotle's own conception theory. There has been renewed interest in such cases in recent years. It is my hope that future specialized studies will increase our knowledge of method and practice in these important case studies and thereby augment our understanding of the genesis and application of biological theories.

These arguments are fairly well known today. It is interesting to note that v. Kries already knew them, and that they have been ignored by Reichenbach and v. Mises in their original account of probability.2This observation leads to the interesting question why the frequency theory of probability has been adopted by many people in our century in spite of severe counterarguments. One may think of a change in scientific attitude, of a scientific revolution put forward by Feyerabendarian propaganda- and who (...) would deny that Reichenbach was an excellent propagandist!My suggested explanation is the following:J. v. Kries is still a mentalist in the tradition of Descartes and Locke. This can be shown very well from his logic, which he wrote even much later (1916). A mentalist does not pose semantical questions in a proper sense: he rather asks which ideas in the human mind make up a concept. And studying probability in this way, he will find in any case that what is in the human mind is first of all an expectation. Therefore, his analysis of the concept of probability will be centered around the concept of expectation.People tended to approach the problem in quite a different way after the scientific revolution which led from mentalism to lingualism. They tended in many cases to use operationalism and to ask how probabilities are determined in science, if they wanted to clear up the meaning of probability. This new aspect of probability, which was caused by looking at it from a new position or standpoint, suggested it to be the limit of relative frequencies in the first instance. This suggestion was so strong that all objections were ignored, and all counterarguments encountered deaf ears.Of course I have used here an oversimplification. Neither was J. v. Kries untouched by Poincaré's conventionalism, which is essentially a movement leading to the breakdown of mentalism; nor was Reichenbach, when he wrote his thesis in 1915, already a lingualist in any respect.Nevertheless, I think that the lingualist revolution, which took place particularly in mathematics and physics, has also changed the attitude towards probability. It would be interesting to corroborate this thesis by extensive study of the history of science in the late 19th century.Besides this historical aspect of v. Kries' theory, there is a systematic one which should be noticed. Though his theory still has a mentalist outlook, many of v. Kries' statements can be translated into the present lingualist idiom and then become most interesting contributions to the present discussion. We shall then state that for v. Kries probabilities appear first of all in probabilistic hypotheses which may or may not be confirmed by empirical data. Therefore, they have a role similar to theoretical concepts.3But that is not the only predominant feature of v. Kries' theory. He is approaching objective probability in a way which is quite unfamiliar to present day philosophers or mathematicians. Objective probabilities are connected with other concepts in three different ways. First of all, probabilistic hypotheses are confirmed by empirically found relative frequencies in a finite series of events. Secondly, they serve as an aid for decisions. And finally, there is a third relationship. Probabilities have to be explained by theories which are in many cases not formulated in probabilistic terms themselves. We can try to understand probability in one of the first two ways via their connection to other concepts. That is what is usually done by interpretations in terms of frequencies or decisions. A third approach, however, is to understand the nature of probability by the way probabilities are explained, and that is what v. Kries does. Such an approach does not seem unusual at all. In many cases the nature of a kind of objects is characterized by giving an explanation. If somebody asks what an eclipse of the moon is, we shall answer - as Aristotle already proposed - by giving an explanation of it. Thus it is quite natural to answer a question as to the nature of probability by describing the general type of explanation of probability distributions in natural or social science. The answer given by v. Kries is - as we know today — of limited validity. Quantum mechanical probabilities are not explainable by Spielräume. V. Kries solution, however, is remarkable in one important respect. It accounts for the time direction of objective probabilities, which are always predictive or forward probabilities, while retrodictive or backward probabilities are always subjective. The relation of objective probabilities to time direction is surely of utmost importance for natural philosophy. I do not know of any other philosophical foundation of probability which takes into account this deep-rooted relation. Therefore, v. Kries' interpretation may help us to understand one of the most intricate puzzles of philosophy. It may be nearly one hundred years old, but is by no means out of date. (shrink)

Carrie Jenkins presents a new account of arithmetical knowledge, which manages to respect three key intuitions: a priorism, mind-independence realism, and empiricism. Jenkins argues that arithmetic can be known through the examination of empirically grounded concepts, non-accidentally accurate representations of the mind-independent world.

Several authors have argued that, assuming we have apriori knowledge of our own thought-contents, semantic externalism implies that we can know apriori contingent facts about the empirical world. After presenting the argument, I shall respond by resisting the premise that an externalist can know apriori: If s/he has the concept water, then water exists. In particular, Boghossian's Dry Earth example suggests that such thought-experiments do not provide such apriori knowledge. Boghossian himself rejects the Dry Earth experiment, however, since it (...) would imply that externalism is true of empty concepts as well as non-empty concepts. Yet in this paper I respond by defending empty-concept externalism, from criticisms suggested by Boghossian and Brown, and recently developed further by Besson. My contention is that an externalist can give a non-ad hoc descriptivist account of empty concepts. Accordingly, apriori self-knowledge does not enable an externalist to know contingent features of the external world. (shrink)

It is commonplace in cognitive science that concepts are individuated in terms of the roles they play in the cognitive lives of thinkers, a view that Jerry Fodor has recently been dubbed ‘Concept Pragmatism’. Quinean critics of Pragmatism have long argued that it founders on its commitment to the analytic/synthetic distinction, since without such a distinction there is plausibly no way to distinguish constitutive from non-constitutive roles in cognition. This paper considers Fodor’s empirical arguments against analyticity, and in particular (...) his arguments against lexical decomposition and definitions, and argues that Concept Pragmatists have two viable options with respect to them. First, Concept Pragmatists can confront them head-on, and argue that they do not show that lexical items are semantically primitive or that lexical concepts are internally unstructured. Second, Pragmatists may accept that these arguments show that lexical concepts are atomic, but insist that this need not entail that Pragmatism is false. For there is a viable version of Concept Pragmatism that does not take lexical items to be semantically structured or lexical concepts to be internally structured. Adopting a version of Pragmatism that takes meaning relations to be specified by inference rules, or meaning postulates, allows one to accept the empirical arguments in favor of Concept Atomism, while at the same time deny that such arguments show that there are no analyticities. The paper concludes by responding to Fodor’s recent objection that such a version of Concept Pragmatism has unhappy consequences concerning the relation between concept constitution and concept possession.

It is argued that mathematical statements are "a posteriori synthetic" statements of a very special sort, To be called "structure-Analytic" statements. They follow logically from the axioms defining the mathematical structure they are describing--Provided that these axioms are "consistent". Yet, Consistency of these axioms is an empirical claim: it may be "empirically verifiable" by existence of a finite model, Or may have the nature of an "empirically falsifiable hypothesis" that no contradiction can be derived from the axioms.

This paper considers the rediscovery of Hegel currently taking place in the analytic philosophy. Going back to the Hegelian texts themselves, I will try to show how they can help to decisively solve some problems of contemporary philosophy. I will concentrate on the theme of knowledge, and especially mathematical knowledge, in relation to Hegelian dialectical logic.

Natural language processing techniques contribute more and more in analyzing legal documents recently, which supports the implementation of laws and rules using computers. Previous approaches in representing a legal sentence often based on logical patterns that illustrate the relations between concepts in the sentence, often consist of multiple words. Those representations cause the lack of semantic information at the word level. In our work, we aim to tackle such shortcomings by representing legal texts in the form of abstract meaning representation, (...) a graph-based semantic representation that gains lots of polarity in NLP community recently. We present our study in AMR Parsing and AMR-to-text Generation specifically for legal domain. We also introduce JCivilCode, a human-annotated legal AMR dataset which was created and verified by a group of linguistic and legal experts. We conduct an empirical evaluation of various approaches in parsing and generating AMR on our own dataset and show the current challenges. Based on our observation, we propose our domain adaptation method applying in the training phase and decoding phase of a neural AMR-to-text generation model. Our method improves the quality of text generated from AMR graph compared to the baseline model. 2018; and “Legal Text Generation fromMeaning Representation”, published in the 32nd International Conference on Legal Knowledge and Information Systems 2019.).

A recent focus on philosophical methodology has reinvigorated ordinary language philosophy with the contention that philosophical inquiry is better served by attending to the ordinary use of language. Taking cues from findings in the social sciences that deploy methods utilizing language, various ordinary language philosophers embrace a guiding mandate: that ordinary language usage is more reflective of our linguistic and conceptual competencies than standard philosophical methods. We analyze two hypotheses that are implicit in the research from which ordinary language approaches (...) take their cues. This pair of optimistic assumptions (a) bind word meanings to properties of their corresponding concepts and (b) regard language as a direct reflection of our underlying cognitive processes and competencies. Polysemy and pragmatics complicate each assumption. Because the ordinary language philosopher’s methodological mandate compels us to consider how individuals process the utterances they encounter in deciphering the communicative intentions of speakers, failing to attend to the import of polysemy and pragmatics in philosophical and empirical methods has the potential to frustrate the aims of their insightful mandate. The significance of those two complications is worked out with the case study of knowledge. (shrink)

This research explores temporal concept drift and temporal alignment in knowledge organization systems. A comparative analysis is pursued using the 1910 Library of Congress Subject Headings, 2020 FAST Topical, and automatic indexing. The use case involves a sample of 90 nineteenth-century Encyclopedia Britannica entries. The entries were indexed using two approaches: 1) full-text indexing; 2) Named Entity Recognition was performed upon the entries with Stanza, Stanford’s NLP toolkit, and entities were automatically indexed with the Helping Interdisciplinary Vocabulary application, using both (...) 1910 LCSH and FAST Topical. The analysis focused on three goals: 1) identifying results that were exclusive to the 1910 LCSH output; 2) identifying terms in the exclusive set that have been deprecated from the contemporary LCSH, demonstrating temporal concept drift; and 3) exploring the historical significance of these deprecated terms. Results confirm that historical vocabularies can be used to generate anachronistic subject headings representing conceptual drift across time in KOS and historical resources. A methodological contribution is made demonstrating how to study changes in KOS over time and improve the contextualization historical humanities resources. (shrink)

Recently, there has been a significant upsurge of interest in what has come to be known as the 'Adoption Problem', first developed by Saul Kripke in 1974. The problem purports to raise a difficulty for Quine’s anti-exceptionalist conception of logic. In what follows, we first offer a statement of the problem and argue that, so understood, it depends upon natural but resistible assumptions. We then use that discussion as a springboard for developing a different adoption problem, arguing that, (...) for a significant class of basic logical principles, there is indeed a difficulty in seeing how they might be ‘freely adopted,’ thereby vindicating something close to the spirit of Kripke’s original claim. This first part of our argument will enforce a significant qualification of Quine’s claim that basic logical principles can be empirically confirmed. In the concluding sections of the paper, we turn to the question, specifically, of the empirical revisability of logic, arguing that when proper attention is paid to the role of reasoning in theory revision, it does indeed emerge that anti-exceptionalism, in full generality, is untenable.

There is a certain dominant tradition, school, ambiance or intellectual community in contemporary philosophy of science which can conveniently be labelled logical empiricism. Now a curious and (I believe) hitherto unremarked change occurred in the accepted methodology of logical empiricism shortly after the end of World War II. Before then accepted forms of argument for philosophical theses about the logic, analysis, or rational reconstruction of science fell into two main categories. Some arguments appealed to familiar or historically attestable facts (...) about the development of science, the declared aims of scientists, etc. in certain areas. Others appealed to criteria of generality, clarity, accuracy, consistency, simplicity, and similar considerations of a systematic nature in the construction of philosophical analyses. Appeals were rarely, if ever, made at that time to intuition. If an intuitive idea was mentioned at all, it was mentioned as something that might suggest a starting-point of enquiry but could not be relied upon, even presumptively, as the ground for a conclusion. But this situation changed markedly from the late '40's onwards. Many arguments came to be rested, quite explicitly, on the alleged intuitive acceptability of certain premisses. In the Carnapian school, for example, the guiding objective of an inductive logician seems no longer to be the rational reconstruction of scientific reasoning but rather the axiomatisation of his own intuitions by the most sophisticated methods available.

Properties and concepts are similar kinds of thing in so far as they are both typically understood to be whatever it is that predicates stand for. However, they are generally supposed to have different identity criteria: for example, heat is the same property as molecular kinetic energy, whereas the concept of heat is different from the concept of molecular kinetic energy. This paper examines whether this discrepancy is really defensible, and concludes that matters are more complex than is generally thought. (...) The distinction between canonical and non-canonical designators, as applied to such entities as propositions, properties and concepts, is examined, as are causal realist accounts of the semantics of such terms as ‘electricity’ and ‘mass’.

Some philosophers find the following thesis attractive: for every logical constant C there is a set of logical rules of inference R such that a subject knows the meaning of C if and only if she accepts the rules in R. I point out some obvious but, apparently, easily forgotten difficulties concerning this thesis.

The laws of classical logic are taken to be logical truths, which in turn are taken to hold objectively. However, we might question our faith in these truths: why are they true? One general approach, proposed by Putnam [8] and more recently Dickson [3] or Maddy [5], is to adopt empiricism about logic. On this view, logical truths are true because they are true of the world alone – this gives logical truths an air of objectivity. Putnam and (...) Dickson both take logical truths to be true in virtue of the world’s structure, given by our best empirical theory, quantum mechanics. This assumes a determinate logical structure of the world given by quantum mechanics. Here, I argue that this assumption is false, and that the world’s logical structure, and hence the related ‘true’ logic, is underdetermined. This leads to what I call empirical conventionalism.

In the epistemological tradition, there are two main interpretations of the semantic relation that an empirical theory may bear to the real world. According to realism, the theory-world relationship should be conceived as truth; according to instrumentalism, instead, it should be limited to empirical adequacy. Then, depending on how empirical theories are conceived, either syntactically as a class of sentences, or semantically as a class of models, the concepts of truth and empirical adequacy assume different and (...) specific forms. In this paper, we review two main conceptions of truth (one sentence-based and one model-based) and two of empirical adequacy (one sentence-based and one model-based), we point out their respective difficulties, and we give a first formulation of a new general view of the theory-world relationship, which we call Methodological Constructive Realism (MCR). We then show how the content of MCR can be further specified and expressed in a definite and precise form. The bulk of the paper shows in detail how it is possible to accomplish this goal for the special case of deterministic dynamical phenomena and their correlated deterministic models. This special version of MCR is formulated as an axiomatic extension of set theory, whose specific axioms constitute a formal ontology that provides an adequate framework for analyzing the two semantic relations of truth and empirical correctness, as well as their connections.
