We propose a revision operator on a stratified belief base, i.e., a belief base that stores beliefs in different strata corresponding to the value an agent assigns to these beliefs. Furthermore, the operator will be defined as to perform the revision in such a way that information is never lost upon revision but stored in a stratum or layer containing information perceived as having a lower value. In this manner, if the revision of one layer leads to the rejection of (...) some information to maintain consistency, instead of being withdrawn it will be kept and introduced in a different layer with lower value. Throughout this development we will follow the principle of minimal change, being one of the important principles proposed in belief change theory, particularly emphasized in the AGM model. Regarding the reasoning part from the stratified belief base, the agent will obtain the inferences using an argumentative formalism. Thus, the argumentation framework will decide which information prevails when sentences of different layers are used for entailing conflicting beliefs. We will also illustrate how inferences are changed and how the status of arguments can be modified after a revision process. (shrink)
. Artificial Intelligence (AI) has long dealt with the issue of finding a suitable formalization for commonsense reasoning. Defeasible argumentation has proven to be a successful approach in many respects, proving to be a confluence point for many alternative logical frameworks. Different formalisms have been developed, most of them sharing the common notions of argument and warrant. In defeasible argumentation, an argument is a tentative (defeasible) proof for reaching a conclusion. An argument is warranted when it ultimately prevails over other (...) conflicting arguments. In this context, defeasible consequence relationships for modelling argument and warrant as well as their logical properties have gained particular attention. This article analyzes two non-monotonic inference operators Carg and Cwar intended for modelling argument construction and dialectical analysis (warrant), respectively. As a basis for such analysis we will use the LDSar framework, a unifying approach to computational models of argument using Labelled Deductive Systems (LDS). In the context of this logical framework, we show how labels can be used to represent arguments as well as argument trees, facilitating the definition and study of non-monotonic inference operators, whose associated logical properties are studied and contrasted. We contend that this analysis provides useful comparison criteria that can be extended and applied to other argumentation frameworks. (shrink)
In this article we explore multiple change operators, i.e., operators in which the epistemic input is a set of sentences instead of a single sentence. We propose two types of change: prioritized change, in which the input set is fully accepted, and symmetric change, where both the epistemic state and the epistemic input are equally treated. In both kinds of operators we propose a set of postulates and we present different constructions: kernel changes and partial meet changes.
The philosophical tradition of liberal political thought has come to see tolerance as a crucial element of a liberal political order. However, while much has been made of the value of toleration, little work has been done on individual-level motivations for tolerant behavior. In this article, we seek to develop an account of the rational motivations for toleration and of where the limits of toleration lie. We first present a very simple model of rational motivations for toleration. Key to this (...) model is an application of David Ricardo’s model of trade to thinking about toleration. This model supports the claim that we always have reasons to be as tolerant as possible. We then explore why we do not always see tolerant attitudes in the actual world, and point to some potential preconditions for toleration that the initial model does not capture. Subsequently, we examine a more detailed model that allows us to investigate more carefully the conditions under which tolerant behavior can be rewarded. We conclude by arguing that a consideration of self-interested motivations for toleration is essential to the success of a robust theory of toleration for a diverse society, but that even this approach has its limitations.

The debates over the future of human population and the earth’s environment, and similar large issues, usually take place without reference to explicit models. Debate would be clarified if such models were employed. We propose that the logistic equation and its extensions like the generalized logistic and the Lotka-Volterra equations, so familiar to ecologists, can easily be modified to model the important "macro" questions that motivated the three thinkers of our title. The long term rate of population growth must normally (...) be controlled by the rate of improvement in K, the carrying capacity of the earth. K will in turn be controlled by the rate of technological progress. The present situation, in which technological improvement (but also perhaps environmental deterioration) are increasing at rates above r, the Malthusian intrinsic rate of natural increase, is probably unique in human history. Can present levels of human prosperity and population growth be sustained? What processes are most likely to determine the answer to this and similar questions? We here sketch a model that endogenizes technological progress and environmental deterioration in the logistic framework. We discuss extensions of the logistic approach to multiple populations, such as other species, and sub-populations, such as human social classes, using the Lotka-Volterra equations. (shrink)

How far do cultures affect the future of the planet? Can the debate on the environment and global warming be influenced by the cultures of East and West understanding each other better? In this consistently provocative dialogue, two of the most influential thinkers of recent times propose that only a 'human revolution' - a shift in the hearts and minds of individuals - can stimulate a revolution in humanity's relationship with the planet. Such a planetary revolution first requires a transformation (...) of moral and political leadership, and an orientation towards the future rather than a preoccupation with the short-termist policies of the present. Responding to humanity's ills from the Buddhist perspective, and with all the accumulated wisdom of the eastern philosophical tradition, Daisaku Ikeda calls for politicians to take as their mainstays a respect for the dignity of life and an eloquence to inspire in people a sense of community and courage. Correspondingly, renowned western economist and scholar of education Ricardo Diez-Hochleitner stresses the importance of proper educational planning and development in addressing the challenges posed by poverty, inequality and climate change. While acknowledging the scale of the task that lies ahead, both men offer an inspiring and hopeful vision for the future. (shrink)
It is agreed by most scholars that the Stoics were compatibilists regarding the relation between responsibility and determinism. On this view, the Stoics depart from two other positions. Unlike some eliminative determinists — labelled in modern discussions “hard-determinists”, but already active in Antiquity — they assert that, despite determinism, there are things that “depend on us”, or are : things for which we are genuinely responsible and for which, therefore, we may justifiably be praised or blamed. But the Stoics also (...) depart from the libertarian or “anti-determinist” 2 a position championed by the Epicureans in the early Hellenistic period and by Alexander of Aphrodisias on behalf of the Peripatetics, towards the end of the second century AD. Unlike the libertarian, who agrees on the incompatibility alleged by the hard-determinist, but preserves responsibility by rejectin necessitation, the Stoics preserve both responsibility and necessitation.

Detractors of Searle’s Chinese Room Argument have arrived at a virtual consensus that the mental properties of the Man performing the computations stipulated by the argument are irrelevant to whether computational cognitive science is true. This paper challenges this virtual consensus to argue for the first of the two main theses of the persons reply, namely, that the mental properties of the Man are what matter. It does this by challenging many of the arguments and conceptions put forth by the (...) systems and logical replies to the Chinese Room, either reducing them to absurdity or showing how they lead, on the contrary, to conclusions the persons reply endorses. The paper bases its position on the Chinese Room Argument on additional philosophical considerations, the foundations of the theory of computation, and theoretical and experimental psychology. The paper purports to show how all these dimensions tend to support the proposed thesis of the persons reply. (shrink)

: In this paper I will examine two conceptions of philosophy that were defended in Latin America during the last century. I believe that both models have to be put away and that we must build a new one, recovering elements of both of them. At the end of my paper I will consider very briefly what can we learn from this in order to construct a genuine philosophical dialogue between the United States and Latin America.
John Searle believes that computational properties are purely formal and that consequently, computational properties are not intrinsic, empirically discoverable, nor causal; and therefore, that an entity’s having certain computational properties could not be sufficient for its having certain mental properties. To make his case, Searle’s employs an argument that had been used before him by Max Newman, against Russell’s structuralism; one that Russell himself considered fatal to his own position. This paper formulates a not-so-explored version of Searle’s problem with computational (...) cognitive science, and refutes it by suggesting how our understanding of computation is far from implying the structuralism Searle vitally attributes to it. On the way, I formulate and argue for a thesis that strengthens Newman’s case against Russell’s structuralism, and thus raises the apparent risk for computational cognitive science too. (shrink)
This paper offers an exposition of Husserl's mature philosophy of mathematics, expounded for the first time in Logische Untersuchungen and maintained without any essential change throughout the rest of his life. It is shown that Husserl's views on mathematics were strongly influenced by Riemann, and had clear affinities with the much later Bourbaki school.
The thesis develops solutions to two main problems for mental realism. Mental realism is the theory that mental properties, events, and objects exist, with their own set of characters and causal powers. The first problem comes from the philosophy of science, where Psillos proposes a notion of scientific realism that contradicts mental realism, and consequently, if one is to be a scientific realist in the way Psillos recommends, one must reject mental realism. I propose adaptations to the conception of scientific (...) realism to make it compatible with mental realism. In the process, the thesis defends computational cognitive science from a compelling argument Searle can be seen to endorse but has not put forth in an organized logical manner. A new conception of scientific realism emerges out of this inquiry, integrating the mental into the rest of nature. The second problem for mental realism arises out of non-reductive physicalism- the view that higher-level properties, and in particular mental properties, are irreducible, physically realized, and that physical properties are sufficient non-overdetermining causes of any effect. Kim’s Problem of Causal Exclusion aims to show that the mental, if unreduced, does no causal work. Consequently, given that we should not believe in the existence of properties that do not participate in causation, we would be forced to drop mental realism. A solution is needed. The thesis examines various positions relevant to the debate. Several doctrines of physicalism are explored, rejected, and one is proposed; the thesis shows the way in which Kim’s reductionist position has been constantly inconsistent throughout the years of debate; the thesis argues that trope theory does not compete with a universalist conception of properties to provide a solution; and shows weakness in the Macdonald’s non-reductive monist position and Pereboom’s constitutional coincidence account of mental causation. The thesis suggests that either the premises of Kim’s argument are consistent, and consequently his reductio is logically invalid, or at least one of the premises is false, and therefore the argument is not sound. Consequently, the Problem of Causal Exclusion that Kim claims emerges out of non-reductive physicalism does not force us to reject mental realism. Mental realism lives on. (shrink)
A renewed concern with Aristotle’s thought about the economic aspects of human life and society can be observed. Aristotle dealt with the economic issues in his practical philosophy. He thus considered ‘the economic’ within an ethical and political frame. This vision is coherent with a specific ontology of ‘the economic’ according to Aristotle. In a recent paper, I analysed this ontology and left its consequences, especially for Ethics and Politics, for another paper. In this article, I firstly summarise the reasoning (...) and conclusions of the aforementioned paper. Then, I extract the ethical and political “lessons” of the Aristotelian conception. I finally add a section with epistemological “lessons”, and consequences for the teaching of Economics. (shrink)
Against several recent interpretations, I argue in this paper that Immanuel Kant's support for enlightened absolutism was a permanent feature of his political thought that fit comfortably within his larger philosophy, though he saw such rule as part of a transition to democratic self-government initiated by the absolute monarch himself. I support these contentions with (1) a detailed exegesis of Kant’s essay "What is Enlightenment?" (2) an argument that Kantian republicanism requires not merely a separation of powers but also a (...) representative democratic legislature, and (3) a demonstration that each stage of a democratic transition can potentially be in an absolute monarch’s short-run self-interest. I conclude the paper by defending Kant's theory of democratization against charges of consequentialism and paternalism and by pointing out its similarity to other accounts of democratic transitions (for example, those of Samuel Huntington and Guillermo O'Donnell), suggesting a previously unnoticed opportunity for cross-fertilization between political philosophy and comparative politics.

Quine’s criticism of the notion of analyticity applies, at best, to Carnap’s notion, not to those of Frege or Husserl. The failure of logicism is also the failure of Frege’s definition of analyticity, but it does not even touch Husserl’s views, which are based on logical form. However, some relatively concrete number-theoretic statements do not admit such a formalization salva veritate. A new definition of analyticity based not on syntactical but on semantical logical form is proposed and argued for.
This paper is concerned with the use of logic to solve philosophical problems. Such use of logic goes counter to the prevailing empiricist tradition in analytic circles. Specifically, model-theoretic tools are applied to three fundamental issues in the philosophy of logic and mathematics, namely, to the issue of the existence of mathematical entities, to the dispute between first- and second-order logic and to the definition of analyticity.
This paper is a follow-up of the first part of the persons reply to the Chinese Room Argument. The first part claims that the mental properties of the person appearing in that argument are what matter to whether computational cognitive science is true. This paper tries to discern what those mental properties are by applying a series of hypothetical psychological and strengthened Turing tests to the person, and argues that the results support the thesis that the Man performing the computations (...) characteristic of understanding Chinese actually understands Chinese. The supposition that the Man does not understand Chinese has gone virtually unquestioned in this foundational debate. The persons reply acknowledges the intuitive power behind that supposition, but knows that brute intuitions are not epistemically sacrosanct. Like many intuitions humans have had, and later deposed, this intuition does not withstand experimental scrutiny. The second part of the persons reply consequently holds that computational cognitive science is confirmed by the Chinese Room thought experiment. (shrink)
This paper focuses on two prominent arguments claiming that physicalism entails reductionism. One is Kim’s causal exclusion argument (CEA), and the other is Papineau’s causal argument. The paper argues that Kim’s CEA is not logically valid and that it is driven by two implausible justifications. One is “Edward’s dictum”, which is alien to non-reductive physicalism and should be rejected. The other is by endorsement of Papineau’s conception of the physical, immanent in Papineau’s causal argument. This argument only arrives at the (...) physical property-property identities by using a conception of the physical that licenses anything to be reductively physical, including putative core anti-physical entities; thus, leaving Papineau’s causal argument and Kim’s CEA without a reductive physicalist conclusion of philosophical interest.

The right to freedom of expression and the democratic system have a directly proportional relationship. Through the exercise of this right we are able to decide who we are, to speak our minds, get information, cast our vote, shape government and hold it to account, and influence our environment so that it becomes the kind of place we wish to lead our lives in. It is within a framework of democratic values that, in my view, the right of freedom of (...) expression makes unique sense and this paper aims to make this claim more precise, cogent and differentiated from alternative libertarian and liberal conceptions. I apply a fairly uncontroversial conception of the proper functions of the right of freedom of expression, to two concrete cases of international controversy: Julian Assange and Wiki Leaks, and Correa v. Palacio and El Universo. Independent of avowed adherence to democracy, supposed bastions of the right of freedom of expression in society such as some major human rights NGO’s, states and the major mass media turn out to be defending undemocratic positions—undermining the authentic right of freedom of expression in society. Crucial underlying functions of the right of freedom of expression in terms of which this right acquires value are achieving individual and collective autonomy, informed democratic control of government by the people and the right to know facts of public interest. Securing the realization of such values furthers the cause of the abolition of domination, while extending the exercise of freedom of expression to the point where it becomes an act of domination is to extend it beyond the sphere in which this freedom is a right. The same happens with the freedom of movement (Art. 13 of The Universal Declaration of Human Rights)—it is a right until the point at which, without reason, my fist impacts your nose. The right of freedom of expression defines a scope for this freedom—it is the scope in which freedom is (at least) not unjust. The libertarian and liberal conceptions of freedom of expression hold a version of the doctrine that the content of any expression is sacrosanct, in that it is to be unlimitedly protected from government intervention, independent of whether it is false or leads to harmful consequences. A more proper way of evaluating an action or policy is with a rights-based approach, common to democratic theory. Actions or policies which maximize the marginal extent to which human rights are respected in practice in a community —amounting to non-domination—are actions or policies worth realizing. (shrink)
Physicalism, if it is to be a significant thesis, should differentiate itself from key metaphysical contenders which endorse the existence of platonic entities, emergent properties, Cartesian souls, angels, and God. Physicalism can never be true in worlds where things of these kinds exist. David Papineau, David Spurrett, and Barbara Montero have recently developed and defended two influential conceptions of physicalism. One is derived from a conception of the physical as the non-mentally-and-non-biologically identifiable. The other is derived from a conception of (...) the physical as the non-sui-generis-mental. The paper looks at the resources available to those conceptions, but argues that each is insufficient to yield a conception of physicalism that differentiates it from key anti-physicalist positions. According to these conceptions, if we lived in a world full of things that clearly cannot be physical, we would still live in a physical world. Thus, such conceptions of physicalism are of little theoretical interest. (shrink)
The current literature on nanoethics focuses on a wide array of topics such as equity, privacy, military, environment, human enhancement, intellectual property, and security. The identification of those topics leads to the adoption of an ethical stance, which we call the in itself dimension . In this article we argue that even though it is correct to identify the areas where ethical problems are imperative to deal with ( in itself dimension ), it is a partial approach. This is because (...) the in itself dimension pays no attention to another ethical stance; one that does not have anything to do with individual or collective responsibilities, but rather with the socio-economic system into which those responsibilities are embedded. We call this second issue the contextual dimension. (shrink)
From the complete three-volume critical edition of Hegel's Lectures on the Philosophy of Religion , this edition extracts the full text and footnotes of the 1827 lectures, making the work available in a convenient form for study. Of the lectures that can be fully reconstructed, those of 1827 are the clearest, the maturest in form, and the most accessible to nonspecialists. In them, readers will find Hegel engaged in lively debates and in important refinements of his treatment of the concept (...) of religion, the Oriental religions and Judaism, Christology, the Trinity, the God-world relationship, and many other topics. This edition contains a new editorial introduction as well as critical annotations on the text and tables, bibliography, and glossary from the complete edition. The result of an international collaborative effort on the part of Walter Jaeschke, Ricardo Ferrara, and Peter C. Hodgson, the new edition is appearing simultaneously in German, English, and Spanish. The English edition has been prepared by a team consisting of Robert F. Brown (University of Delaware), Peter C. Hodgson (Vanderbilt University), and J. Michael Stewart (Farnham, England), with the assistance of H. S. Harris (York University). (shrink)
We prove strong completeness of the □-version and the ◊-version of a Gödel modal logic based on Kripke models where propositions at each world and the accessibility relation are both infinitely valued in the standard Gödel algebra [0,1]. Some asymmetries are revealed: validity in the first logic is reducible to the class of frames having two-valued accessibility relation and this logic does not enjoy the finite model property, while validity in the second logic requires truly fuzzy accessibility relations and this (...) logic has the finite model property. Analogues of the classical modal systems D, T, S4 and S5 are considered also, and the completeness results are extended to languages enriched with a discrete well ordered set of truth constants.

Standard economic theory teaches that trade benefits all countries involved, at least in the long run. While there are other reasons for trade liberalization, this insight, going back to Ricardo's 1817 Principles of Political Economy , continues to underlie international economics. Trade also raises fairness questions. First, suppose A trades with B while parts of A's population are oppressed. Do the oppressed in A have a complaint in fairness against B? Should B cease to trade? Second, suppose because of (...) oppression or lower social standards, A's products are cheaper than B's. Can industries in B legitimately insist that their government take measures to help them compete? The Pauper-Labor Argument makes that case, and many economists enjoy dismissing it in undergraduate classes. Third, suppose A subsidizes its industries. If this lowers world market prices, does B have a fairness complaint against A? Ought countries to consider how trade policies affect others? This article is the first of two, which together develop a view that is meant to serve as a reference point for moral assessments of international trade policies. I develop this view by way of offering affirmative answers to these three questions. Since this discussion is organized around these three questions, the two studies can be read independently of each other. Key Words: the state • World Trade Organization • development • oppression • exploitation. (shrink)
Possibly the most comprehensive collection of essays on Descartes' scientific writings ever published, this volume offers a detailed reassessment of his scientific work and its bearing on his philosophy. The 35 essays, written by some of the world's leading scholars, cover topics as diverse as optics, cosmology and medicine. The collection looks at Descartes' work in the sciences as an aspect of his natural-philosophical agenda and discusses: the central place of medicine in Descartes' overall project; the connections between his investigations (...) of specific psychological capacities and his ethics of self-government; and the debates and controversies into which he had his followers were drawn, and their role in shaping Cartesian natural philosophy; and other issues.

Husserl's contributions to the nature of mathematical knowledge are opposed to the naturalist, empiricist and pragmatist tendences that are nowadays dominant. It is claimed that mainstream tendences fail to distinguish the historical problem of the origin and evolution of mathematical knowledge from the epistemological problem of how is it that we have access to mathematical knowledge.
Within the perception-action framework, the underlying mechanisms of empathy and its related processes of moral behavior need to be investigated. fMRI studies have shown different frontal cortex activation patterns during automatic processing and judgment tasks when stimuli have moral content. Clinical neuropsychological studies reveal different patterns of empathic alterations after dorsolateral versus orbital frontal cortex damage, related to deficient cognitive and emotional processing. These processing streams represent different neural levels and mechanisms underlying empathy.
In this paper the structuralist approach of theory reconstruction is applied to International Trade Theory. In the basic element the universal laws of the theory are stated and the general concepts are defined in terms of three sets and seven functions. Ricardo’s Theory of Comparative Advantage and the Factor Proportions Theory by Heckscher and Ohlin are reconstructed as specialisations of the basic element. Two intratheoretical constraints are formulated in order to ensure the consistency of the theory. A number of (...) empirical studies are shown to be paradigmatic, successful or questionable applications of International Trade Theory. The reconstruction allows the assessment of the theory from a metatheoretical angle and illuminates the logical interdependencies of its components. (shrink)
Frege had not one but two different notions of sense, namely, that of ?Über Sinn und Bedeutung? and one implicit in a letter to Husserl of 1906 and elsewhere. This last one originates in Frege's notion of conceptual content. The distinction is used to clarify some obscurities in Frege's thought. In the last section a sort of ?explicans? of Frege's notion of conceptual content is introduced and applied to the semantic analysis of mathematics.
This paper sustains that reappraising Austrian economics in the light of Aristotelian ideas is not only possible but also fruitful. First, the paper draws a sketch of the essential features of Austrian economics. Next, it argues about the necessity for a thorough analysis of the notion of freedom, and it analyzes Mises's conception. Next, the paper exposes Aristotle's social, epistemological and economic thought related to Austrian main traits. An account of how the exercise of Aristotelian virtues may be synergic with (...) economic coordination and a sketch of the consequences of the proposal on the teaching of economics are then provided. Finally, the conclusion shortly sums up the content and relevance of Aristotle's contribution. (shrink)
Oaksford and Chater (1994) proposed to analyse the Wason selection task as an inductive instead of a deductive task. Applying Bayesian statistics, they concluded that the cards that participants tend to select are those with the highest expected information gain. Therefore, their choices seem rational from the perspective of optimal data selection. We tested a central prediction from the theory in three experiments: card selection frequencies should be sensitive to the subjective probability of occurrence for individual cards. In Experiment 1, (...) expected frequencies of the p- and the q-card were manipulated independently by concepts referring to large vs. small sets. Although the manipulation had an effect on card selection frequencies, there was only a weak correlation between the predicted and the observed patterns. In the second experiment, relative frequencies of individual cards were manipulated more directly by explicit frequency information. In addition, participants estimated probabilities for the four logical cases and of the conditional statement itself. The experimental manipulations strongly affected the probability estimates, but were completely unrelated to card selections. This result was replicated in a third experiment. We conclude that our data provide little support for optimal data selection theory. (shrink)
Political judgment is notoriously hard to theorise, and in the recent debates surrounding Habermas's discourse ethics we encounter classic disagreements around the nature, operation and validity of such judgments. This paper evaluates Habermas's account of political judgment and explores the problems raised by his critics. It then focuses on the contentious role played by universals within his account. What emerges is a reformulated theory of judgment based on the thin universalism of fair deliberation, and a description of a sub-set of (...) judgments, termed ``democratic judgments'', which are oriented to the preservation of democracy.

One of the most influential studies in all expertise research is de Groot’s (1946) study of chess players, which suggested that pattern recognition, rather than search, was the key determinant of expertise. Many changes have occurred in the chess world since de Groot’s study, leading some authors to argue that the cognitive mechanisms underlying expertise have also changed. We decided to replicate de Groot’s study to empirically test these claims and to examine whether the trends in the data have changed (...) over time. Six Grandmasters, five International Masters, six Experts, and five Class A players completed the think-aloud procedure for two chess positions. Findings indicate that Grandmasters and International Masters search more quickly than Experts and Class A players, and that both groups today search substantially faster than players in previous studies. The findings, however, support de Groot’s overall conclusions and are consistent with predictions made by pattern recognition models. (shrink)
This article begins by pointing out the difficulties involved by the insertion of freedom in economics: It poses epistemological problems that are not satisfactorily solved by the standard theories. The article suggests that the Aristotelian epistemological frame of practical rationality may be an apt position from which one can deal with freedom in economics. Aristotle's concepts of society and economics are first introduced. The role of virtues in achieving economic coordination is exposed. Then the corresponding concept of practical science is (...) described, showing its main characteristics and how they fit in with traditional political economy. The concept of value neutrality receives special attention in the article: A reinterpretation of the meaning of it is proposed. The article concludes that Aristotle's broad concepts of practical reason and science leave room for a more comprehensive notion of economics. (shrink)
s book, Hermeneutic Dialogue and Social Science: A critique of Gadamer and Habermas, intends to present an account of debates on objectivity in the social sciences, in stressing the political and epistemological responsibility, in public spheres, to those who want to create a fairer understanding of societies and history, without demonizing natural enterprises or leaving social studies out of acute critical questioning. Key Words: dialogue • hermeneutic • social sciences • natural sciences • method.
Wealth of Nations was published in 1776. Among the people who took up its ideas were Jeremy Bentham (b. 1748). Bentham and James Mill were friendly also with David Ricardo and Thomas Malthus. Ricardo's Principles of Political Economy & Taxation (1817) was written at James Mill's suggestion; 'it is almost certain that he would not have finished it without Mill's continuous encouragement' (R.M. Hartwell, 'Introduction' to Ricardo's Principles (Penguin), p.13). James Mill published his own Elements of Political (...) Economy in 1821. James Mill's son was John Stuart Mill (b. 1806). The younger Mill began to make an impact as a writer of newspaper articles in the 1820s. His Logic was published in 1843, Principles of Political Economy in 1848. He died in 1873, almost a century after the publication of the Wealth of Nations. (shrink)
The philosophy of economics has been largely guided by analytic philosophy. Even Marx has been appropriated without much scandal by economists who separate his scientific contributions from his politics. In this article, I place philosophical hermeneutics (i.e., Heidegger and Ricoeur) in dialogue with the conventional understanding of land as a factor of production. The history of political economy misunderstands land as an entity classifiable as property and capital. I argue instead that land's ontological role, deriving from Heidegger's concept of earth, (...) suggests that economics needs to account for it in a new way according to David Ricardo's notion of land rent.

Leading figures in ancient philosophy present nineteen original papers on three key themes in the work of Richard Sorabji. The papers dealing with Metaphysics range from Democritus to Numenius on basic questions about the structure and nature of reality: necessitation, properties, and time.

The section devoted to Ethics concentrates upon Stoicism (...) and the complex views the Stoics held on such topics as motivation, akrasia, oikeitsis, and the emotions. It also includes one paper on the influence of Greek ethics in Modern Philosophy. The volume also contains a fascinating "intellectual autobiography" by Sorabji himself, and a full Bibliography of his works. (shrink)
We analyze the connections of Lavoisier system of nomenclature with Leibniz’s philosophy, pointing out to the resemblance between what we call Leibnizian and Lavoisian programs. We argue that Lavoisier’s contribution to chemistry is something more subtle, in so doing we show that the system of nomenclature leads to an algebraic system of chemical sets. We show how Döbereiner and Mendeleev were able to develop this algebraic system and to find new interesting properties for it. We pointed out the resemblances between (...) Leibniz program and Lavoisier legacy, particularly regarding the lingua philosophica for understanding and thinking Nature, in this particular case, chemistry. In the second part we discuss, from the linguistic viewpoint, how Lavoisian algebraic system may be taken further to build a language. We study the constituents of such a chemical language. Finally, we formalize some of the ideas here presented by using elements of network theory and discrete mathematics. (shrink)
We introduce and study a new approach to the theory of abstract algebraic logic (AAL) that explores the use of many-sorted behavioral logic in the role traditionally played by unsorted equational logic. Our aim is to extend the range of applicability of AAL toward providing a meaningful algebraic counterpart also to logics with a many-sorted language, and possibly including non-truth-functional connectives. The proposed behavioral approach covers logics which are not algebraizable according to the standard approach, while also bringing a new (...) algebraic perspective to logics which are algebraizable using the standard tools of AAL. Furthermore, we pave the way toward a robust behavioral theory of AAL, namely by providing a behavioral version of the Leibniz operator which allows us to generalize the traditional Leibniz hierarchy, as well as several well-known characterization results. A number of meaningful examples will be used to illustrate the novelties and advantages of the approach. (shrink)

Quine’s criticism of the notion of analyticity applies, at best, to Carnap’s notion, not to those of Frege or Husserl. The failure of logicism is also the failure of Frege’s definition of analyticity, but it does not even touch Husserl’s views, which are based on logical form. However, some relatively concrete number-theoretic statements do not admit such a formalization salva veritate. A new definition of analyticity based not on syntactical but on semantical logical form is proposed and argued for.
We review different studies of the Periodic Law and the set of chemical elements from a mathematical point of view. This discussion covers the first attempts made in the 19th century up to the present day. Mathematics employed to study the periodic system includes number theory, information theory, order theory, set theory and topology. Each theory used shows that it is possible to provide the Periodic Law with a mathematical structure. We also show that it is possible to study the (...) chemical elements taking advantage of their phenomenological properties, and that it is not always necessary to reduce the concept of chemical elements to the quantum atomic concept to be able to find interpretations for the Periodic Law. Finally, a connection is noted between the lengths of the periods of the Periodic Law and the philosophical Pythagorean doctrine. (shrink)
This paper discusses Husserl’s views on physical theories in the first volume of his Logical Investigations , and compares them with those of his contemporaries Pierre Duhem and Henri Poincaré. Poincaré’s views serve as a bridge to a discussion of Husserl’s almost unknown views on physical geometry from about 1890 on, which in comparison even with Poincaré’s—not to say Frege’s—or almost any other philosopher of his time, represented a rupture with the philosophical tradition and were much more in tune with (...) the physical geometry underlying the Einstein-Hilbert general theory of relativity developed more than two decades later.

Agricultural engineers’ jobs are especially related to sustainability and earth life issues. They usually work with plants or animals, and the aim of their work is often linked to producing food to allow people to improve their quality of life. Taking into account this dual function, the moral requirements of their day-to-day professional practice are arguably greater than those of other professions. Agricultural engineers can develop their ability to live up to this professional responsibility by receiving ethical training during their (...) university studies, not only by taking courses specifically devoted to ethics, but also by having to deal with moral questions that are integrated into their technical courses through a program of Ethics Across the Curriculum (EAC).

Framed within the dialectic of the causal exclusion argument (Kim 2005), this paper does two things. One, it clarifies some properties of multiple realizability based on its true origin (Turing 1950). And two, it challenges a form of argument Noordhof (1997), Clarke (1999), and Whittle (2007) employ to support the idea that the mental has causal powers not had by its physical realization base (Novel). The paper challenges Novel with ideas derived from multiple realizability, among others.
A novel algebraic structure of the genetic code is proposed. Here, the principal partitions of the genetic code table were obtained as equivalent classes of quotient spaces of the genetic code vector space over the Galois field of the four DNA bases. The new algebraic structure shows strong connections among algebraic relationships, codon assignment and physicochemical properties of amino acids. Moreover, a distance function defined between the codon binary representations in the vector space was demonstrated to have a linear behavior (...) respect to physical variables such as the mean of amino acids interaction energies in proteins. It was also noticed that the distance between wild type and mutant codons approach to smaller values in mutational variants of four genes, i.e., human phenylalanine hydroxylase, human β-globin, HIV-1 protease and HIV-1 reverse transcriptase. These results strongly suggest that deterministic rules must be involved in the genetic code origin. (shrink)
We present here a digital scenario to simulate the emergence of self-organized symbol-based communication among artificial creatures inhabiting a virtual world of predatory events. In order to design the environment and creatures, we seek theoretical and empirical constraints from C.S.Peirce Semiotics and an ethological case study of communication among animals. Our results show that the creatures, assuming the role of sign users and learners, behave collectively as a complex system, where self-organization of communicative interactions plays a major role in the (...) emergence of symbol-based communication. We also strive for a careful use of the theoretical concepts involved, including the concepts of symbol, communication, and emergence, and we use a multi-level model as a basis for the interpretation of inter-level relationships in the semiotic processes we are studying.

The ´, or world's con flagration, followed by the restoration of an identical world seems to go against the rationality of the Stoic god. The aim of this paper is to show that Cleanthes, the second head of the School, can avoid this paradox. According to Cleanthes, the con flagration is an inevitable side-effect of the necessary means used by god to sustain the world. Given that this side-effect is contrary to god's sustaining activity, but unavoidable, god's rationality requires the (...) restoration of an identical world once the con flagration subsides. The paper also deals with the relation between Cleanthes and other early Stoics on the topic of con flagration. In particular, Cleanthes' position seems to diff er from Chrysippus'. For in contrast with the Cleanthean god, who causes the con flagration as a side-effect only, the Chrysippean god, according to an in fluential interpretation put forward by Jaap Mansfeld, causes the con flagration as his ultimate cosmological goal.

The moral ideology of banking and insurance employees in Spain was examined along with supervisor role modeling and ethics-related policies and procedures for their association with ethical behavioral intent. In addition to main effects, we found evidence supporting that the person–situation interactionist perspective in supervisor role modeling had a stronger positive relationship with ethical intention among employees with relativist moral ideology. Also as hypothesized, formal ethical polices and procedures were positively related to ethical intention among those with universal beliefs, but (...) the relationship was much weaker among relativists. Thus, firms wishing to optimally promote ethical attitudes and behavior must tailor their organization-based initiatives to the individual characteristics of their employees. (shrink)
The cross-cultural literature is reviewed and integrated together with attitude theories, thereby outlining a model through which certain values influence the intervening variables that ultimately lead managers to tolerate employee bribery. The case of Latin America is employed to illustrate how regionally dominant cultural values may shape managers' attitudes, subjective norms, and perceived behavioral control, which in turn affect tolerance of employee bribery. A series of research propositions and practical recommendations are derived from the model.
The dilemma confronted by Buridan’s Ass leads into a problem about nil-preference situations, to which there is a solution in the literature that is inspired by Alan Turing: we have evolved with a computational module in our brains that comes into play in such situations by picking a random action among the alternatives that detennines the subject’s choice. We relate these Buridan’s Ass situations to a larger, theoretically interesting category in which there is no alternative that is decisively superior to (...) others with respect to expected utility, and we try to show how our emotional makeup figures in a rational response, particularly as informed by symbolic utilitythat we draw down from our culture’s shared understandings. The category is theoretically interesting because it contains moral dilemmas, as well as hard cases in which an imponant choice must be made without an option that has clearly superior expected utility. We argue that our Emotional Response Model is preferable to Turing’s Randomizer for this category, as well as more illuminating about nil-preference situations or close approximations thereto.

Marx was an exponent of the 'Labour theory' of value, held also by Adam Smith, Ricardo, James Mill, John Stuart Mill and some early 19th century political economists. This is the theory that human labour is the sole source of value (of exchange value), and that the value of a commodity is the quantity of socially necessary labour embodied in it. When we exchange commodities they exchange in the ratio of the quantities of labour required to produce them and (...) bring them into the market. (shrink)
