Concept representation is still an open problem in the field of ontology engineering and, more generally, of knowledge representation. In particular, the issue of representing “non classical” concepts, i.e. concepts that cannot be defined in terms of necessary and sufficient conditions, remains unresolved. In this paper we review empirical evidence from cognitive psychology, according to which concept representation is not a unitary phenomenon. On this basis, we sketch some proposals for concept representation, taking into account suggestions from psychological research. In (...) particular, it seems that human beings employ both prototype-based and exemplar-based representations in order to represent non classical concepts. We suggest that a similar, hybrid prototype-exemplar based approach could also prove useful in the field of knowledge representation technology. Finally, we propose conceptual spaces as a suitable framework for developing some aspects of this proposal. (shrink)

A review of Carsten Herrmann-Pillath, Foundations of Economic Evolution. A Treatise on the Natural Philosophy of Economics. I argue that the author's ultra-naturalist stance in epistemology lacks consistent justification.

Deductive inference is usually regarded as being “tautological” or “analytical”: the information conveyed by the conclusion is contained in the information conveyed by the premises. This idea, however, clashes with the undecidability of first-order logic and with the (likely) intractability of Boolean logic. In this article, we address the problem both from the semantic and the proof-theoretical point of view. We propose a hierarchy of propositional logics that are all tractable (i.e. decidable in polynomial time), although by means of growing (...) computational resources, and converge towards classical propositional logic. The underlying claim is that this hierarchy can be used to represent increasing levels of “depth” or “informativeness” of Boolean reasoning. Special attention is paid to the most basic logic in this hierarchy, the pure “intelim logic”, which satisfies all the requirements of a natural deduction system (allowing both introduction and elimination rules for each logical operator) while admitting of a feasible (quadratic) decision procedure. We argue that this logic is “analytic” in a particularly strict sense, in that it rules out any use of “virtual information”, which is chiefly responsible for the combinatorial explosion of standard classical systems. As a result, analyticity and tractability are reconciled and growing degrees of computational complexity are associated with the depth at which the use of virtual information is allowed. (shrink)

The literature on algorithmic fairness has examined exogenous sources of biases such as shortcomings in the data and structural injustices in society. It has also examined internal sources of bias as evidenced by a number of impossibility theorems showing that no algorithm can concurrently satisfy multiple criteria of fairness. This paper contributes to the literature stemming from the impossibility theorems by examining how informational richness affects the accuracy and fairness of predictive algorithms. With the aid of a computer simulation, we (...) show that informational richness is the engine that drives improvements in the performance of a predictive algorithm, in terms of both accuracy and fairness. The centrality of informational richness suggests that classification parity, a popular criterion of algorithmic fairness, should be given relatively little weight. But we caution that the centrality of informational richness should be taken with a grain of salt in light of practical limitations, in particular, the so-called bias-variance trade off. (shrink)

This paper examines the idea of education of the citizen derived from the texts of Rousseau, with particular attention to the role assigned to patriotism and civil religion. With respect to patriotic education, I critically question Rousseau's thesis about the incompatibility between love of one’s country and a sense of humanity, contrasting them with the idea of constitutional patriotism, founded on loyalty to universal values. I conclude with an examination of the idea that a civil religion constitutes an essential contribution (...) to the citizen’s education. I believe that the public ethics of political liberalism are better suited to the idea of civic education for democracy. (shrink)

Since the early eighties, computationalism in the study of the mind has been “under attack” by several critics of the so-called “classic” or “symbolic” approaches in AI and cognitive science. Computationalism was generically identified with such approaches. For example, it was identified with both Allen Newell and Herbert Simon’s Physical Symbol System Hypothesis and Jerry Fodor’s theory of Language of Thought, usually without taking into account the fact ,that such approaches are very different as to their methods and aims. Zenon (...) Pylyshyn, in his influential book Computation and Cognition, claimed that both Newell and Fodor deeply influenced his ideas on cognition as computation. This probably added to the confusion, as many people still consider Pylyshyn’s book as paradigmatic of the computational approach in the study of the mind. Since then, cognitive scientists, AI researchers and also philosophers of the mind have been asked to take sides on different “paradigms” that have from time to time been proposed as opponents of (classic or symbolic) computationalism. Examples of such oppositions are: -/- computationalism vs. connectionism, computationalism vs. dynamical systems, computationalism vs. situated and embodied cognition, computationalism vs. behavioural and evolutionary robotics. -/- Our preliminary claim in section 1 is that computationalism should not be identified with what we would call the “paradigm (based on the metaphor) of the computer” (in the following, PoC). PoC is the (rather vague) statement that the mind functions “as a digital computer”. Actually, PoC is a restrictive version of computationalism, and nobody ever seriously upheld it, except in some rough versions of the computational approach and in some popular discussions about it. Usually, PoC is used as a straw man in many arguments against computationalism. In section 1 we look in some detail at PoC’s claims and argue that computationalism cannot be identified with PoC. In section 2 we point out that certain anticomputationalist arguments are based on this misleading identification. In section 3 we suggest that the view of the levels of explanation proposed by David Marr could clarify certain points of the debate on computationalism. In section 4 we touch on a controversial issue, namely the possibility of developing a notion of analog computation, similar to the notion of digital computation. A short conclusion follows in section 5. (shrink)

Many philosophers have pointed out that statistical evidence, or at least some forms of it, lack desirable epistemic or non-epistemic properties, and that this should make us wary of litigations in which the case against the defendant rests in whole or in part on statistical evidence. Others have responded that such broad reservations about statistical evidence are overly restrictive since appellate courts have expressed nuanced views about statistical evidence. In an effort to clarify and reconcile, I put forward an interpretive (...) analysis of why statistical evidence should raise concerns in some cases but not others. I argue that when there is a mismatch between the specificity of the evidence and the expected specificity of the accusation, statistical evidence—as any other kind of evidence—should be considered insufficient to sustain a conviction. I rely on different stylized court cases to illustrate the explanatory power of this analysis. (shrink)

The paper argues for the plausibility of the thesis that there are no genuine moral dilemmas. In particular, I examine Bernard Williams’ objection that agentregret in a situation of conflict among contradictory moral obligations would prove the existence of such dilemmas. Contrary to Williams’claim, agentregret in these situations is not sufficient to establish the existence of such moral dilemmas. Williams’ argument cannot undermine the logical consistency of moral theories, nor their capacity to solve moral conflicts. I also consider Monika Betzler’s (...) proposal that agentregret can be considered ‘rational in a looser sense’ without implying an inconsistency in moral theory. In order to discuss the plausibility of this proposal, I focus on the interpretation of agentregret as an emotional response which also restores offended moral integrity. I claim, in conclusion, that it is reasonable to assume this proposal, insofar as moral theory can determine some criteria of judgement which allow a distinction between authentic and false modalities of integration.

La logica modale è nata per studiare i ragionamenti su ciò che è possibile e ciò che è necessario. Negli ultimi decenni, a partire dal lavoro di logici e filosofi quali Rudolf Carnap, Saul Kripke e David Lewis, la sua applicazione è stata progressivamente estesa ad altri ambiti, quali il ragionamento sul tempo, sulla conoscenza e sui sistemi di norme. Queste ricerche hanno condotto a un complesso e intrigante dialogo con alcune fondamentali branche della filosofia: la metafisica, l’epistemologia, la filosofia (...) del linguaggio. Lo scopo del volume è offrire una panoramica di questo dialogo al contempo accessibile e rigorosa, pensata sia per gli studenti di un corso universitario, sia per il lettore non specialista. Se da un lato tutte le necessarie nozioni tecniche sono rese accessibili ai non addetti ai lavori, dall'altro si restituisce un'immagine fedele delle sfide concettuali che la ricerca in questi settori è oggi chiamata ad affrontare.

Embodiment matters to perception and action. Beyond the triviality that, under normal circumstances, we need a body in order to perceive the world and act in it, our particular embodiment, right here, right now, both enables and constrains our perception of possibilities for action. In this chapter, we provide empirical support for the idea that the structural and morphological features of the body can narrow the set of our possible interactions with the environment by shaping the way we perceive the (...) possibilities for action provided. We argue that this narrowing holds true in the perception of what we call strongly embodied affordances, that is, relevant micro-affordances that have a genuinely demanding characteristic, as well as in the perception of actions performed by others. In particular, we show that perceptual contents are shaped by fine-grained morphological features of the body, such as specific hand-shapes, and that they change according to our possibility to act upon them with this body, in this situation, at this moment. We argue that these considerations provide insight into distinguishing a variety of experienced affordance relations that can aid us in better understanding the relevance of embodiment for perception and experience.

A discussion of the relationship between Ricardo and his Unitarian Minister Thomas Belsham, a New Testament scholar and the author of a philosophical treatise inspired by the Hartley-Priestley philosophy.

According to the principle of epistemic closure, knowledge is closed under known implication. The principle is intuitive but it is problematic in some cases. Suppose you know you have hands and you know that ‘I have hands’ implies ‘I am not a brain-in-a-vat’. Does it follow that you know you are not a brain-in-a-vat? It seems not; it should not be so easy to refute skepticism. In this and similar cases, we are confronted with a puzzle: epistemic closure is an (...) intuitive principle, but at times, it does not seem that we know by implication. In response to this puzzle, the literature has been mostly polarized between those who are willing to do away with epistemic closure and those who think we cannot live without it. But there is a third way. Here I formulate a restricted version of the principle of epistemic closure. In the standard version, the principle can range over any proposition; in the restricted version, it can only range over those propositions that are within the limits of a given epistemic inquiry and that do not constitute the underlying assumptions of the inquiry. If we adopt the restricted version, I argue, we can preserve the advantages associated with closure, while at the same time avoiding the puzzle I’ve described. My discussion also yields an insight into the nature of knowledge. I argue that knowledge is best understood as a topic-restricted notion, and that such a conception is a natural one given our limited cognitive resources. (shrink)

I describe both the German Aristotelian revival and the Anglo-Saxon virtue-ethics approach and argue that there are some reasons why Grotus's dismissal of Aristotelian practical rationality had finally to be overcome. I suggest that such reasons in turn depend on deeper changes in the structure of the building of modern philosophy, first among them those carried by the critique of Cartesian foundationalism staged by such odd bed-fellows as Peirce, Wittgenstein, Husserl, and Heidegger, adding quasi-Thomist such as Anscombe and Geach. This (...) may account for the apparently unexpected normative turn which took place in the same years (shortly after or before 1958) in two different and comparatively insulated contexts such as Germany and the Anglo-Saxon world.

A short presentation of James Steuart's neglected philosophical publications as well as of his well-known economic contribution.

Smith argues that, unlike other forms of evidence, naked statistical evidence fails to satisfy normic support. This is his solution to the puzzles of statistical evidence in legal proof. This paper focuses on Smith’s claim that DNA evidence in cold-hit cases does not satisfy normic support. I argue that if this claim is correct, virtually no other form of evidence used at trial can satisfy normic support. This is troublesome. I discuss a few ways in which Smith can respond.

As it emerged from philosophical analyses and cognitive research, most concepts exhibit typicality effects, and resist to the efforts of defining them in terms of necessary and sufficient conditions. This holds also in the case of many medical concepts. This is a problem for the design of computer science ontologies, since knowledge representation formalisms commonly adopted in this field (such as, in the first place, the Web Ontology Language - OWL) do not allow for the representation of concepts in terms (...) of typical traits. The need of representing concepts in terms of typical traits concerns almost every domain of real world knowledge, including medical domains. In particular, in this article we take into account the domain of mental disorders, starting from the DSM-5 descriptions of some specific disorders. We favour a hybrid approach to concept representation, in which ontology oriented formalisms are combined to a geometric representation of knowledge based on conceptual space. As a preliminary step to apply our proposal to mental disorder concepts, we started to develop an OWL ontology of the schizophrenia spectrum, which is as close as possible to the DSM-5 descriptions.

Come è emerso dall’analisi filosofica e dalla ricerca nelle scienze cogni- tive, la maggior parte dei concetti, tra cui molti concetti medici, esibisce degli “effetti prototipici” e non riesce ad essere definita nei termini di condizioni necessarie e sufficienti. Questo aspetto rappresenta un problema per la pro- gettazione di ontologie in informatica, poiché i formalismi adottati per la rap- presentazione della conoscenza (a partire da OWL – Web Ontology Langua- ge) non sono in grado di rendere conto dei concetti nei (...) termini dei loro tratti prototipici. Nel presente articolo ci concentriamo sulla classe dei disordini mentali facendo riferimento alle descrizioni che ne vengono date nel DSM-5. L’idea è quella di proporre un approccio ibrido, in cui i formalismi delle ontologie sono combinati a una rappresentazione geometrica della conoscenza basata sugli spazi concettuali. (shrink)

Nel campo delle scienze cognitive molti oggi condividono l’ipotesi che siano necessari differenti tipi di rappresentazioni per modellare i sistemi cognitivi sia naturali, sia artificiali. Si considerino le rappresentazioni basate su reti neurali, i formalismi simbolici e rappresentazioni analogiche quali rappresentazioni diagrammatiche o modelli mentali. Tutti questi metodi hanno successo nello spiegare e modellare alcune classi di fenomeni cognitivi, ma nessuno è in grado di rendere conto di tutti gli aspetti della cognizione. A partire da queste considerazioni, riteniamo che sistemi (...) intelligenti e architetture cognitive possano trarre vantaggio dalla combinazione di sistemi di rappresentazione diversi. Si pone allora il problema di fare interagire rappresentazioni di natura differente in maniera cognitivamente e teoricamente fondata. La nostra ipotesi è che gli spazi concettuali possano offrire una sorta di lingua comune, che consentirebbe di integrare e generalizzare molti aspetti delle impostazioni sopra menzionate, superando i limiti delle varie proposte intese singolarmente.

A brief reconstruction of the birth, rise and ironical destiny of an almost universal expansion to other disciplines going with a dissolution within the original birthplace of the conception of an economic man, a male-only abstraction forgetful of its own abstract character.

A discussion of the historical development of the relationship between moral philosophy and political economy and economics qua disciplines, followed by a treatment of questions of justice in the contemporary discussion and then by an overview of the subdiscipline of busness ethics.

Many oppose the use of profile evidence against defendants at trial, even when the statistical correlations are reliable and the jury is free from prejudice. The literature has struggled to justify this opposition. We argue that admitting profile evidence is objectionable because it violates what we call “equal protection”—that is, a right of innocent defendants not to be exposed to higher ex ante risks of mistaken conviction compared to other innocent defendants facing similar charges. We also show why admitting other (...) forms of evidence, such as eyewitness, trace, and motive evidence, does not violate equal protection. (shrink)

In this paper I argue that applied ethics is a phenomenon spontaneously emerged between the Sixties and the Seventies and resulting from interbreeding of theoretical discussion in ethics and public discourse of liberal-democratic societies. I contend that the phenomenon’s novelty is in a peculiar relationship it has helped in establishing between ethical theories and real-world issues, and besides that the true nature of applied ethics is that of deliberation, whose tool is the faculty of judgment, or casuistry, understood the Kantian (...) way.

The paper is a comparative study of the methodologies of Malthus and Ricardo. Its claims are: (i) economic laws almost always admit of exceptions for Malthus; for Ricardo even contingent predictions allow no exception apart from random temporary variations; (ii) both rely on the prestigious Newtonian paradigm, while interpreting it according to two distinct methodological traditions (the one deriving from MacLaurin, the other from Priestley); (iii) the choice of stressing what happens during intervals or in permanent states leads to opposing (...) definitions of the main problem of economic science in so far as equilibrium is always already given for Ricardo and is never given for Malthus; (iv) their use of the ambiguous notion of "tendency" leaves unclear for both the degree of predictive power with which theories are endowed; (v) what both share is the idea of a natural order and this idea is the source of both shortcomings and endless disagreement. -/- .

The discovery of the role of models in science by Granger parallels the analogous discovery made by Mary Hesse and Marx Wartofsky. The role models are granted highlights the linguistic dimension of science, resulting in a 'softening' of Bachelard's rationalistic epistemology without lapsing into relativism. A 'linguistic' theory of metaphor, as contrasted with Bachelard's 'psychological' theory, is basic to Granger's account of models. A final paragraph discusses to what extent Granger's 'mature' theory of models would imply a revision of his (...) early economic methodology. (shrink)

The unresolved dilemma of Marxian theory is whether the overall social constellation may legitimately be called 'mode of production' because mono-causal economic explanations are acceptable or whether there is instead a more complex causality at the level of the 'ökonomische Gesellschaftsformation', i.e. the social constellation as a whole.

A discussion of the birth and adventures of a concept created by Marxist authors at the time of the Russian revolution, sometimes under the term 'economic materialism' and the subsequent discussion by Polanyi of Marx's own economicist fallacy.

Recent contributions by Kuhn, Wartofsky, and Granger, converge in the direction of an extended view of models, one that acknowledges a metaphorical dimension in the language of science. Such a view is in some respects the opposite of the views of both Bachelard and the Logical Empiricists. A number of familiar puzzles of the philosophy of science, such as the problem of reference, the opposition of realism and instrumentalism, that between explanation and understanding, and the status of scientific objectivity, may (...) receive a new solution in the light of the Kuhn/Wartofsky/Granger view of scientific metaphors.

The paper discusses Ricardo's relationship to Mill and Bentham. It discusses first the origins of the myth of Ricardo's dependence from Bentham through Mill, and Halévy's contribution to the freezing of such a myth. The paper reconstructs what were their shared political commitments and activities and the kind of specific political views and agenda that may be ascribed to Ricardo himself. The paper discusses then the question of Ricardo's adhesion to Benthamite ethics. It examines fragments in Ricardo's correspondence with Maria (...) Edgeworth and Francis Place, and adds fresh light on the issue by highlighting the partial overlapping between Bentham's ethics and the kind of intuitionism with theological consequentialism that Ricardo had learned from the Unitarian minister Thomas Belsham.

We reconstruct the text, that is, we analyse the development of the discussion between Malthus and Ricardo both in the correspondence and in published works, paying special attention to (a) the use of methodological statements, (b) some pragmatic features of the controversy, (c) considerations pertaining to the meta-level of the controversy (assessments of the status of the controversy, of ways of solving it, etc.); then, we reconstruct the co-text, that is, unpublished papers by each opponent that were not made available (...) to the other, records of exchanges between each of these and third parties, etc.; thirdly, we describe the essential features of the context, focusing on events that influenced the course of the controversy; (iv) we draw lessons from our case study on the role of co-text and context, on pragmatic and semantic interpretation, and on "casts of mind”.

The primary aim of this chapter is to explain the nature of evidential reasoning, the characteristic difficulties encountered, and the tools to address these difficulties. Our focus is on evidential reasoning in criminal cases. There is an extensive scholarly literature on these topics, and it is a secondary aim of the chapter to provide readers the means to find their way in historical and ongoing debates.

We present a module based criterion, i.e. a sufficient condition based on the absolute value of the matrix coefficients, for the convergence of Gauss–Seidel method (GSM) for a square system of linear algebraic equations, the Generalized Line Criterion (GLC). We prove GLC to be the “most general” module based criterion and derive, as GLC corollaries, some previously know and also some new criteria for GSM convergence. Although far more general than the previously known results, the proof of GLC is simpler. (...) The results used here are related to recent research in stability of dynamical systems and control of manufacturing systems. (shrink)

This note discusses three issues that Allen and Pardo believe to be especially problematic for a probabilistic interpretation of standards of proof: (1) the subjectivity of probability assignments; (2) the conjunction paradox; and (3) the non-comparative nature of probabilistic standards.

Recently the educational task of the public school has been repeatedly challenged. Citizenship has not been spared from criticism and its legitimacy has been questioned. The article discusses the issue of the legitimacy of citizenship education in public schools, specifying the meaning of neutrality of which it proposes a narrow interpretation. On this basis the article examines four philosophical models of citizenship education (communitarianism, civic humanism, liberalism, republicanism). The analysis suggests that the republican model of citizenship education is the most (...) appropriate; it needs however a liberal adaptation. The proposed solution of a liberal republicanism is illustrated with a critical examination of the duty of civility. (shrink)
