In order to understand the Gricean "logic of conversation" that underlies the Nicomachean Ethics, Burger believes it necessary to identify the audience to which the work is addressed: this is the audience of men and citizens who have received a good education, that is, have learned the virtues through habit, but have doubts about the content of the education received, that is, about the beautiful and the just. Aristotle proposes on the one hand to give them reasons to defend (...) and justify the moral virtues they have learned and they practice, but on the other hand also to lead them to understand a dimension that goes beyond the horizon of traditional ethos.

A short reconstruction of the notion of passion in ancient ethics, its transformation in modern moral and political philosophy and its demise after the end of the eighteenth-century.

The genealogical deconstruction of the notion of "good" by F.Nietzsche in Genealogy of Morals highlights the arbitrariness of the Platonic unification of various kinds of good, a unification that is still shared by both objectivists and subjectivists. For the same reasons, the attempt of G.E. Moore and other neo-intuitionists to define a single property that is common to all uses of the term "good" and the specular denial of the existence of this property by the emotionalism of A.J. Ayer and (...) Ch.L. Stevenson perhaps debate a false problem. The revival of various forms of Aristotelianism has proposed again Aristotle's answer to Plato: when we say something is good, we want to know what is good, and the answer will be different for different goods.

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)

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.

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)

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)

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.

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)

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.

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)

In the present paper, we shall discuss the notion of prototype and show its benefits. First, we shall argue that the prototypes of common-sense concepts are necessary for making prompt and reliable categorisations and inferences. However, the features constituting the prototype of a particular concept are neither necessary nor sufficient conditions for determining category membership; in this sense, the prototype might lead to conclusions regarded as wrong from a theoretical perspective. That being said, the prototype remains essential to handling most (...) ordinary situations and helps us to perform important cognitive tasks. To exemplify this point, we shall focus on disease concepts. Our analysis concludes that the prototypical conception of disease is needed to make important inferences from a practical and clinical point of view. Moreover, it can still be compatible with a classical definition of disease, given in terms of necessary and sufficient conditions. In the first section, we shall compare the notion of stereotype, as it has been introduced in philosophy of language by Hilary Putnam, with the notion of prototype, as it has been developed in the cognitive sciences. In the second section, we shall discuss the general role of prototypical information in cognition and stress its centrality. In the third section, we shall apply our previous discussion to the specific case of medical concepts, before briefly summarising our conclusions in section four. (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. I offer a reading of probabilistic standards that avoids these criticisms.

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.

The paper focuses on the kind of expertise required by doctors in health communication and argues that such an expertise is twofold: both epistemological and communicative competences are necessary to achieve compliance with the patient. Firstly, we introduce the specific epistemic competences that deal with diagnosis and its problems. Secondly, we focus on the communicative competences and argue that an inappropriate strategy in communicating the reasons of diagnosis and therapy can make patient compliance unworkable. Finally, we focus on the case (...) of diabetes metaphor and propose the deliberate use of metaphors in health communication as an educational tool. On the one hand, metaphors might help doctors in explaining the disease in simpler terms and framing the experience of illness according to patient’s specific needs. On the other hand, metaphors might encourage a change in patient’s beliefs on their own experience of illness, and enable them to reach a shared decision making with doctors. (shrink)

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.

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 reconstruct a plot in the twentieth-century Anglo-Saxon ethical discussion. I discuss first the reasons why in the first half of the twentieth century the claim of a neutral character of metaethics vis-a-vis normative ethics was generally accepted; then I discuss the reasons for a U-turn that took place in 1958, which brought back to the forefront two traditional schools of normative ethics, Kantian and Utilitarian, and the reasons for criticism from the new school of virtue ethics. I conclude by (...) the claim that intuitionism and Kantian ethics will still be on the agenda for some time. (shrink)

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.

A short discussion of Charles Taylor's masterwork.

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.

The novelty in Smith’s way of looking at the economy is the discovery of a social character of wealth, something new in comparison with its definition in physical terms by the Physiocrats. The possibility of carrying out such an idealization was a result of the adoption of a Newtonian, as opposed to a Cartesian, epistemology, where an intermediate and provisional character of theoretical entities is explicitly accepted, dropping Cartesian strong epistemological realism.

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 origins of the very notion of development, its role in eocnomic thoery, and its discussion in applied ethics.

A discussion, based on Pownall's reading of ‘The Wealth of Nations’, of the Newtonian heritage in Adam Smith's project of a moral science encompassing political economy as one of its sub-disciplines and refusing any essentialist grounding of the theory in ultimate characteristics of human nature.

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.

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)

Abstract The paper reconstructs the reception of Descartes's work by the Scottish Enlighteners, from Colin MacLaurin to Dugald Stewart. The Scots' image of Descartes was a byproduct of a scientific controversy; philosophical arguments were brought into the picture more as asides than as a primary focus of interest. As soon as the Cartesian physics withered away as a real alternative to Newtonian physics, only the philosophical arguments were left, with no memory of the context out of which they originated, and (...) the focus of the discussion shifts from physics to the philosophy of mind and the theory of knowledge.

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)

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)

Both Adam Smith's epistemology and his politics head to a stalemate. The former is under the opposing pulls of an essentialist ideal of knowledge and of a pragmatist approach to the history of science. The latter still tries to provide a foundation for a natural law, while conceiving it as non-absolute and changeable. The consequences are (i) inability to complete both the political and the epistemological works projected by Smith; (ii) decentralization of the social order, giving rise to several partial (...) orders, such as that of the market.

During the last decades, many cognitive architectures (CAs) have been realized adopting different assumptions about the organization and the representation of their knowledge level. Some of them (e.g. SOAR [35]) adopt a classical symbolic approach, some (e.g. LEABRA[ 48]) are based on a purely connectionist model, while others (e.g. CLARION [59]) adopt a hybrid approach combining connectionist and symbolic representational levels. Additionally, some attempts (e.g. biSOAR) trying to extend the representational capacities of CAs by integrating diagrammatical representations and reasoning are (...) also available [34]. In this paper we propose a reflection on the role that Conceptual Spaces, a framework developed by Peter G¨ardenfors [24] more than fifteen years ago, can play in the current development of the Knowledge Level in Cognitive Systems and Architectures. In particular, we claim that Conceptual Spaces offer a lingua franca that allows to unify and generalize many aspects of the symbolic, sub-symbolic and diagrammatic approaches (by overcoming some of their typical problems) and to integrate them on a common ground. In doing so we extend and detail some of the arguments explored by G¨ardenfors [23] for defending the need of a conceptual, intermediate, representation level between the symbolic and the sub-symbolic one. In particular we focus on the advantages offered by Conceptual Spaces (w.r.t. symbolic and sub-symbolic approaches) in dealing with the problem of compositionality of representations based on typicality traits. Additionally, we argue that Conceptual Spaces could offer a unifying framework for interpreting many kinds of diagrammatic and analogical representations. As a consequence, their adoption could also favor the integration of diagrammatical representation and reasoning in CAs. (shrink)

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)

I argue the existence of two tensions in Smith's system of ideas: the first is that between the postulate of an invisible noumenal order of the universe and the imaginary principles by means of which we connect the phenomena; the second is a tension between the noumenal order of the world where 'is' and 'ought' converge, and the various partial orders that may be reconstructed in social phenomena that leave room for irrationality and injustice. My first claim is that these (...) tensions are dialectical tensions in a unitary, albeit rhapsodically presented in writing. My second claim is that, the system’s unanswered question in the moral domain is a ‘metaphysical’ and ‘theological’ question, namely the problem of evil; by implication, I contend also that Smith was no secularist, but instead a post-skeptical fideist or agnostic, who took Bayle's question: "why are men wicked and unhappy?" quite seriously. His private ethics of prudence, justice, benevolence and his public ethics of liberty, justice, equality were modest proposals for coping with the problem of social evil in our imperfect world.

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.

The relationship between Adam Smith's official methodology and his own actual theoretical practice as a social scientist may be grasped only against the background of the Humean project of Moral Newtonianism. The main features in Smith's methodology are (i) the provisional character of explanatory principles, (ii) 'internal' criteria of truth, (iii) the acknowledgement of an imaginative aspect in principles, with the related problem of the relationship between internal truth and external truth understood as mirroring 'real' causes. Smith's Newtonian (as opposed (...) to Cartesian) methodology makes room for progress in social theorizing as it allows for a decentralization of the various fields of Moral Science, contributing to the shaping of political economy. On the other hand, the Cartesian legacy in Smith's Newtonian methodology makes the relationship problematic between phenomena and principles. (shrink)

A new translation and edition of Aristotle's Protrepticus (with critical comments on the fragments) -/- Welcome -/- The Protrepticus was an early work of Aristotle, written while he was still a member of Plato's Academy, but it soon became one of the most famous works in the whole history of philosophy. Unfortunately it was not directly copied in the middle ages and so did not survive in its own manuscript tradition. But substantial fragments of it have been preserved (...) in several works by Iamblichus of Chalcis, a third century A.D. neo-Pythagorean philosopher and educator. On the basis of a close study of Iamblichus' extensive use and excerption of Aristotle's Protrepticus, it is possible to reconstruct the backbone of the lost work, and then to flesh it out with the other surviving reports about the work from antiquity (for example in Alexander of Aphrodisias and other ancient commentators on Aristotle). It is also possible to identify several papyrus fragments of the work, and many references and literary allusions in later authors, especially Cicero, whose own lost dialogue Hortensius was a defense of philosophy modeleld on Aristotle's.

I comment on two analyses of the Simonshaven case: one by Prakken (2019), based on arguments, and the other by van Koppen and Mackor (2019), based on scenarios (or stories, narratives).

To illustrate this point, I focus on the defense argument during the appeal trial and show that both analyses face difficulties in modeling key (...) features of this argument. (shrink)

A short reconstruction of the birth and development of the doctrine of non-violence.

: The theory of objective value is the central feature in the paradigm of political economy. The Newtonian heritage plays a major role in giving political economy the status of a self-standing empirical science, and a reconstruction of this heritage casts fresh light on the idea of value and its role in the definition of the subject matter of political economy. Cognitive progress carried by classical political economy turns out to be related with the dilemmas of Newtonian epistemology and the (...) alternative between essentialist realism and instrumental conventionalism.

I argue that Kant took from Moses Mendelssohn the idea of a distinction between geometry of morals and a practical ethic. He was drastically misunderstood by his followers precisely on this point. He had learned from the sceptics and the Jansenists the lesson that men are prompted to act by deceptive ends, and he was aware that human actions are also empirical phenomena, where laws like the laws of Nature may be detected. His practical ethics made room for judgment as (...) a holistic procedure for assessing the salience of relevant moral qualities in one given situation; this procedure yields the same results as the geometry of morals does for abstract cases, but does so immediately and without balancing conflicting duties with each other, since what makes for the salient quality of a situation is perceived from the very beginning.

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. -/- .
