It is widely supposed that evolutionary debunking arguments against morality constitute a type of epistemological objection to our moral beliefs. In particular, the debunking force of such arguments is not supposed to depend on the metaphysical claim that moral facts do not exist. In this paper I argue that this standard epistemological construal of EDAs is highly misleading, if not mistaken. Specifically, I argue that the most widely discussed EDAs all make key and controversial metaphysical claims about the nature of (...) morality or the possibility of moral truth that belie their apparently epistemological character. I show that the debunking force of these EDAs derives largely from metaphysical claims about morality and their implications for the possibility of moral reduction, rather than from epistemological worries associated with the existence of an causal/non-moral explanation of our moral judgments. The paper briefly concludes with a dilemma that I believe confronts all EDAs such as those discussed in this paper: either such arguments are unsound, or else they prove too much, debunking our knowledge of science and the external world, as well as morality.

A ‘companions in guilt’ strategy against moral error theory aims to show that the latter proves too much: if sound, it supports an implausible error-theoretic conclusion in other areas such as epistemic or practical reasoning. Christopher Cowie [2016 Cowie, C. 2016. Good News for Moral Error Theorists: A Master Argument Against Companions in Guilt Strategies, Australasian Journal of Philosophy 94/1: 115–30.[Taylor & Francis Online], [Web of Science ®] [Google Scholar]] has recently produced what he claims is a ‘master argument’ against (...) all such strategies. The essence of his argument is that CG arguments cannot work because they are afflicted by internal incoherence or inconsistency. I argue, first, that Cowie's master argument does not succeed. Beyond this, I argue that there is no good reason to think that any such argument—one that purports to identify an internal incoherence in CG arguments—can succeed. Second, I argue that the main substantive area of disagreement between error theorists and CG theorists essentially concerns the conceptual profile of epistemic reasons—specifically, whether they are strongly categorical—not the ontological question of whether such reasons exist. I then develop an argument in favour of the CG theorist's position by considering the moral error theorist's arguments in support of the conceptual claim that moral reasons are strongly categorical. These include, notably, criticisms made by Joyce [2011] and Olson [2014] of Finlay's [2008] ‘end relational’ view of morality, according to which moral reasons are relative to some end or standard, hence not strongly categorical. Examining these criticisms, I argue that, based on what moral error theorists have said regarding the conceptual profile of moral reasons, there is a strong case to be made that moral reasons are strongly categorical if and only if epistemic reasons are.

Following Post program, we will propose a linguistic and empirical interpretation of Gödel’s incompleteness theorem and related ones on unsolvability by Church and Turing. All these theorems use the diagonal argument by Cantor in order to find limitations in finitary systems, as human language, which can make “infinite use of finite means”. The linguistic version of the incompleteness theorem says that every Turing complete language is Gödel incomplete. We conclude that the incompleteness and unsolvability theorems find limitations in our finitary (...) tool, which is our complete language. (shrink)

Escritos de estética y semiótica del arte, pp. 44-121). Las mismas han sido enriquecidas como resultado del debate que, generación tras generación, sobre ellas hemos sostenido con los estudiantes —la mayoría de ellos hoy egresados del posgrado en Estética y Arte de la BUAP—. Es un trabajo que lleva su huella y (...) ningún marco mejor para incluirlo que el de este libro de la serie Academia y Egresados de la Colección La Fuente.

Computer simulations have conventionally been understood to be either extensions of formal methods such as mathematical models or as special cases of empirical practices such as experiments. Here, I argue that computer simulations are best understood as instruments. Understanding them as such can better elucidate their actual role as well as their potential epistemic standing in relation to science and other scientific methods, practices and devices.

The dating of Hero of Alexandria has been linked with the lunar eclipse of March 13, ad 62, since Otto Neugebauer discovered that this eclipse is the only one that can fit the one described in Hero’s Dioptra 35. Although only a number of scholars claim that Hero himself observed the eclipse, almost all of them take Neugebauer’s identification for granted. We use statistical and linguistic methods to criticize this assumption: all indices we have found point to the fact that (...) the eclipse was merely invented as an example and, for that reason, that it cannot be used to determine Hero’s life span.

In this paper I argue that Artificial Intelligence and the many data science methods associated with it, such as machine learning and large language models, are first and foremost epistemic technologies. In order to establish this claim, I first argue that epistemic technologies can be conceptually and practically distinguished from other technologies in virtue of what they are designed for, what they do and how they do it. I then proceed to show that unlike other kinds of technology (_including_ other (...) epistemic technologies) AI can be uniquely positioned as an epistemic technology in that it is primarily designed, developed and deployed to be used in _epistemic contexts_ such as inquiry, it is specifically designed, developed and deployed to manipulate _epistemic content_ such as data, _and_ it is designed, developed and deployed to do so particularly through _epistemic operations_ such as prediction and analysis. As has been shown in recent work in the philosophy and ethics of AI (Alvarado, AI and Ethics, 2022a), understanding AI as an epistemic technology will also have significant implications for important debates regarding our relationship to AI technologies. This paper includes a brief overview of such implications, particularly those pertaining to explainability, opacity, trust and even epistemic harms related to AI technologies. (shrink)

One of the main tools in the study of nonmonotonic consequence relations is the representation of such relations in terms of preferential models. In this paper we give an unified and simpler framework to obtain such representation theorems.

The best known algebraizable logics with a conjunction and an implication have the property that the conjunction defines a meet semi-lattice in the algebras of their algebraic counterpart. This property makes it possible to associate with them a semi-lattice based deductive system as a companion. Moreover, the order of the semi-lattice is also definable using the implication. This makes that the connection between the properties of the logic and the properties of its semi-lattice based companion is strong. We introduce a (...) class of algebraizable deductive systems that includes those systems, and study some of their properties and of their semi-lattice based companions. We also study conditions which, when satisfied by a deductive system in the class, imply that it is strongly algebraizable. This brings some information on the open area of research of Abstract Algebraic Logic which consists in finding interesting characterizations of classes of algebraizable logics that are strongly algebraizable.

Leibniz filters play a prominent role in the theory of protoalgebraic logics. In [3] the problem of the definability of Leibniz filters is considered. Here we study the definability of Leibniz filters with parameters. The main result of the paper says that a protoalgebraic logic S has its strong version weakly algebraizable iff it has its Leibniz filters explicitly definable with parameters.

A logic in a finite language is said to be finitely presentable if it is axiomatized by finitely many finite rules. It is proved that binary non-indexed products of logics that are both finitely presentable and finitely equivalential are essentially finitely presentable. This result does not extend to binary non-indexed products of arbitrary finitely presentable logics, as shown by a counterexample. Finitely presentable logics are then exploited to introduce finitely presentable Leibniz classes, and to draw a parallel between the Leibniz (...) and the Maltsev hierarchies. (shrink)

A logic is selfextensional if its interderivability (or mutual consequence) relation is a congruence relation on the algebra of formulas. In the paper we characterize the selfextensional logics with a conjunction as the logics that can be defined using the semilattice order induced by the interpretation of the conjunction in the algebras of their algebraic counterpart. Using the charactrization we provide simpler proofs of several results on selfextensional logics with a conjunction obtained in [13] using Gentzen systems. We also obtain (...) some results on Fregean logics with conjunction. (shrink)

The positive fragment of the local modal consequence relation defined by the class of all Kripke frames is studied in the context ofAlgebraic Logic. It is shown that this fragment is non-protoalgebraic and that its class of canonically associated algebras according to the criteria set up in [7] is the class of positive modal algebras. Moreover its full models are characterized as the models of the Gentzen calculus introduced in [3].

Notoriously, state-building is a key enterprise in regard of addressing the international conflicts throughout the globe. The consolidation of peace associated to it is intimately connected with the institutionalization of liberal ideas in structuring realms such as the political, the economical and the social spheres. Departing from Foucauldian concepts such as dispositif, government, discipline and biopolitics, this paper aims to critically analyze the post-conflict state-building practice. In a first moment, the paper delineates how peace was operationalized during the Cold War (...) and post-Cold War periods. In a second moment, it will present the Foucauldian conceptual tools that enables the (re)problematization of the state-building practice as a post-conflict normalizing dispositif, rather than merely a conflict-resolution tool.

The solution attributed to Archytas for the problem of doubling the cube is a landmark of the pre-Euclidean mathematics. This paper offers textual arguments for a new reading of the text of Archytas’ solution for doubling the cube, and an approach to the solution which fits closely with the new reading. The paper also reviews modern attempts to explain the text, which are as complicated as the original, and its connections with some xvi-century mathematical results, without any documented relation to (...) Archytas’ doubling the cube. (shrink)

Empirical studies have revealed a disturbing prevalence of research misconduct in a wide variety of disciplines, although not, to date, in the areas of ethics and philosophy. This study aims to provide empirical evidence on perceptions of how serious a problem research misconduct is in these two disciplines in Spain, particularly regarding the effects that the model used to evaluate academics’ research performance may have on their ethical behaviour. The methodological triangulation applied in the study combines a questionnaire, a debate (...) at the annual meeting of scientific association, and in-depth interviews. Of the 541 questionnaires sent out, 201 responses were obtained, with a significant difference in the participation of researchers in philosophy and in ethics ; 26 researchers took part in the debate and 14 interviews were conducted. The questionnaire results reveal that 91.5% of the respondents considered research misconduct to be on the rise; 63.2% considered at least three of the fraudulent practices referred to in the study to be commonplace, and 84.1% identified two or more such practices. The researchers perceived a high prevalence of duplicate publication and self-plagiarism, use of personal influence and citation manipulation, in contrast to a low perceived incidence of data falsification or fabrication. The debate and the interviews corroborated these data. Researchers associated the spread of these misconducts with the research evaluation model applied in Spain. (shrink)

In the present paper we study systematically several consequence relations on the usual language of propositional intuitionistic logic that can be defined semantically by using Kripke frames and the same defining truth conditions for the connectives as in intuitionistic logic but without imposing some of the conditions on the Kripke frames that are required in the intuitionistic case. The logics so obtained are called subintuitionistic logics in the literature. We depart from the perspective of considering a logic just as a (...) set of theorems and also depart from the perspective taken by Restall in that we consider standard Kripke models instead of models with a base point. We study the relations between subintuitionistic logics and modal logics given by the translation considered by Došen. Moreover, we classify the logics obtained according to the hierarchy considered inAlgebraic Logic. (shrink)

Artificial intelligence is a useful predictive tool for a wide variety of fields of knowledge. Despite this, the educational field is still an environment that lacks a variety of studies that use this type of predictive tools. In parallel, it is postulated that the levels of self-esteem in the university environment may be related to the strategies implemented to solve problems. For these reasons, the aim of this study was to analyze the levels of self-esteem presented by teaching staff and (...) students at university and to design an algorithm capable of predicting these levels on the basis of their coping strategies, resilience, and sociodemographic variables. For this purpose, the Rosenberg Self-Esteem Scale, the Perceived Stress Scale, and the Brief Resilience Scale were administered. The results showed a relevant role of resilience and stress perceived in predicting participants’ self-esteem levels. The findings highlight the usefulness of artificial neural networks for predicting psychological variables in education. (shrink)

We consider the equationally orderable quasivarieties and associate with them deductive systems defined using the order. The method of definition of these deductive systems encompasses the definition of logics preserving degrees of truth we find in the research areas of substructural logics and mathematical fuzzy logic. We prove several general results, for example that the deductive systems so defined are finitary and that the ones associated with equationally orderable varieties are congruential.

Psychology related to areas such as gender, language, education and violence has provided scientific knowledge that is contributing to reducing coercive social relationships and to expanding freedom in sexual-affective relationships. Nonetheless, today there are new challenges that require additional developments. In the area of consent, professionals from the fields of law, gender, education and others, are in need of evidence about conditions in human communication that produce consent differentiating them from conditions that coerce. Up to now, consent has been focused (...) on verbal language, for example, “no means no” or “anything less than yes is no”. Despite the fact that focusing consent on verbal language is a very important part of the problem, and has meant a huge advance, it does not solve most of the issues currently raised, like the famous case of “La Manada” in Spain. This article presents the most recent results of a new line of research, which places the problem and the solution in communicative acts, and not only in speech acts. Even though there might be a “yes” in a sexual-affective relationship, there might be no consent, and it is indeed a coercive relationship if that “yes” has been pronounced in a relationship determined by institutional power or by interactive power. Institutional power may occur if who made the proposal for the relationship is a person in charge of the process of selecting personnel in a company and one of the candidates is the person who received the proposal. Interactive power may occur if who makes the proposal is situated in an equal or inferior position for instance in the company to the person receiving it, but the former threatens to make sextortion to the latter. The potential social impact of this research has been already shown in the cases analyzed for this study. (shrink)
