In this paper, an attempt is made to solve various problems posed to current theories of verisimilitude: the problem of linguistic variance; the problem of which are the best scientific methods for getting the most verisimilar theories; and the question of the ontological commitment in scientific theories. As a result of my solution to these problems, and with the help of other considerations of epistemological character, I conclude that the notion of 'Tarskian truth' is dispensable in a rational interpretation of (...) the scientific enterprise. As a logical result, however, falsificationism will be vindicated. (shrink)

An epistemic notion of verisimilitude (as the 'degree in which a theory seems closer to the full truth to a scientific community') is defined in several ways. Application to the structuralist description of theories is carried out by introducing a notion of 'empirical regularity' in structuralist terms. It is argued that these definitions of verisimilitude can be used to give formal reconstructions of scientific methodologies such as falsificationism, conventionalism and normal science.

Scientists can choose different claims as interpretations of the results of their research. Scientific rhetoric is understood as the attempt to make those claims most beneficial for the scientists' interests. A rational choice, game-theoretic model is developed to analyze how this choice can be made and to assess it from a normative point of view. The main conclusion is that `social' interests (pursuit of recognition) may conflict with `cognitive' ones when no constraints are put on the choices of the authors (...) of scientific papers, as in an `ideal free speech situation'. Scientific institutions may help to solve this conflict. Lastly, some empirical predictions are offered that can inspire future social research of the refereeing process. (shrink)

The scientist's decision of accepting a given proposition is assumed to be dependent on two factors: the scientist's 'private' information about the value of that statement and the proportion of colleagues who also accept it. This interdependence is modelled in an economic fashion, and it is shown that it may lead to multiple equilibria. The main conclusions are that the evolution of scientific knowledge can be path, dependent, that scientific revolutions can be due to very small changes in the empirical (...) evidence, and that not all possible equilibria are necessarily efficient, neither in the economic nor in the epistemic sense. These inefficiencies, however, can be eliminated if scientists can form coalitions. (shrink)

Some peculiarities of the evaluation of theories within scientific research programmes and of the assessing of rival SRPs are described assuming that scientists try to maximise an ‘epistemic utility function’ under economic and institutional constraints. Special attention is given to Lakatos' concepts of ‘empirical progress’ and ‘theoretical progress’. A notion of ‘empirical verisimilitude’ is defended as an appropriate utility function. The neologism ‘methodonomics’ is applied to this kind of studies.

The decision whether to have a realist or an anti-realist attitude towards scientific hypotheses is interpreted in this paper as a choice that scientists themselves have to face in their work as scientists, rather than as a ‘philosophical’ problem. Scientists’ choices between realism and instrumentalism are interpreted in this paper with the help of two different conceptual tools: a deflationary semantics grounded in the inferentialist approach to linguistic practices developed by some authors, and an epistemic utility function that tries to (...) represent the cognitive preferences of scientists. The first tool is applied to two different questions traditionally related to the problem of scientific realism: the non-miracle argument, and the continuity of reference. The second one is applied to the problem of unconceived alternatives, and to the distinction between realist and instrumentalist attitudes towards scientific hypotheses. (shrink)

The connection between scientific knowledge and our empirical access to realityis not well explained within the structuralist approach to scientific theories. I arguethat this is due to the use of a semantics not rich enough from the philosophical pointof view. My proposal is to employ Sellars–Brandom's inferential semantics to understand how can scientific terms have empirical content, and Hintikka's game-theoretical semantics to analyse how can theories be empirically tested. The main conclusions are that scientific concepts gain their meaning through `basic (...) theories' grounded on `common sense, and that scientific method usually allows the pragmatic verification and falsification of scientific theories.

Moulines’ arguments against several types of realism in his book Pluralidad y recursion are considered and a defence of scientific realism consistent with structuralism is offered as a plausible answer to Moulines’ criticisms.

The process of scientific investigation is reconstructed as a process of empirical approximation to the truth. This last concept is explicated as a combination of “degree of simmilarity between theory A and the strongest accepted empirical law at moment t” and the “degree of depth of this empirical law”. A number of methodological theorems are proved, and avision of science closer to sophisticated falsificationism is mathematically deduced from our definitions.

Methodological norms are seen as rules defining a competitive game, and it is argued that rational recognition-seeking scientists can reach a collective agreement about which specific norms serve better their individual interests, especially if the choice is made `under a veil of ignorance', i.e. , before knowing what theory will be proposed by each scientist. Norms for theory assessment are distinguished from norms for theory choice (or inference rules), and it is argued that pursuit of recognition only affects this second (...) type of rule. An inference rule similar to `eliminative induction' is defended on the basis of such a possible agreement. According to this contractarian approach, both the explanation and the justification of scientific norms only need to refer to the preferences of individual scientists, without assuming the existence of `collective' points of view.

Open peer commentary on the article “Lived Experience and Cognitive Science Reappraising Enactivism’s Jonasian Turn” by Mario Villalobos & Dave Ward. Upshot: Villalobos and Ward reappraise enactivism’s “Jonasian turn” and discover an untenable anthropomorphism at its core. As a corrective to this, the authors propose a Maturanian-inspired account of experience that could accommodate central enactive insights while avoiding anthropomorphism. In this commentary, I will delve a bit deeper into Villalobos and Ward’s treatment of anthropomorphism. In so doing, I will show (...) that the notion of anthropomorphism trades on an ambiguity that leaves the authors’ own position open to accusations of anthropomorphism and that it needs further justification for why it is at odds with science. I conclude with a few words on why the authors’ assessment of a similar proposal by myself is unfounded. (shrink)

Being scientific research a process of social interaction, this process can be studied from a game-theoretic perspective. Some conceptual and formal instruments that can help to understand scientific research as a game are introduced, and it is argued that game theoretic epistemology provides a middle ground for 'rationalist' and 'constructivist' theories of scientific knowledge. In the first part , a description of the essential elements of game of science is made, using an inferentialist conception of rationality. In the second part (...) , some ideas for the reconstruction of case studies are introduced, and applied to one example: Latour's analysis of Joliot's attempt to build an atomic bomb. Lastly, in the third part , a formal analysis of the constitution of scientific consensus is offered. (shrink)

In this paper, we analyse the most important documents establishing the criteria for the treatment and exclusion of COVID-19 patients, especially in regard to the giving of respiratory support, in Italy and Spain. These documents reflect a tension that stems from limited healthcare resources which are insufficient to save lives that, under normal conditions, could have been saved, or at least could have received the best possible treatment. First, we analyse the healthcare systems of these two countries before the spread (...) of the virus, both of which have seen decreases in the number of intensive care beds and have been marked by financial cuts during the last ten years. It is a fact that a greater number of people, especially those over 70 years of age, have been left without respiratory support treatment, and therefore, there have been a greater number of deaths. It is also a fact that there has been a higher infection rate among healthcare professionals due to the delay in the management of protective measures and the inability to provide adequate care for those in nursing homes, as recognised by WHO. In the context of this health emergency, healthcare professionals have suffered a real ‘moral distress’ because, knowing first-hand the causes of the limitation of resources, they have had to put triage protocols into practice. Finally, we set forth a series of concrete ethical proposals with which to face the successive waves of COVID-19 infection, as well as other future pandemics. (shrink)

This study aims to investigate the relationship between job burnout and employee performance in the feed industry during the ASF outbreak. Further, the researchers employed a descriptive-correlational research design in order to analyze the acquired data and produce pertinent findings. Thus, the researchers gathered data from one hundred two (102) feed industry employees. The Maslach Burnout Inventory (MBI) and Individual Work Performance Questionnaire (IWPQ) were employed to ascertain the extent of job burnout experienced by the respondents and evaluate employee performance, (...) respectively. Based on the statistical analysis, there is a significant relationship between job burnout and employee performance. Moreover, the study's findings were thoroughly analyzed and discussed. (shrink)

The aim of this research was to establish linear relations (association and prediction) and inferential relations between three constructs at different levels of psychological research –executive dysfunction(microanalysis),self-regulation(molecular level), andself-vs.external regulation(molar level), in the prediction of emotion regulation difficulties. We hypothesized that personal and contextual regulatory factors would be negatively related to levels of executive dysfunction and emotion regulation difficulties; by way of complement, non-regulatory and dysregulatory personal, and contextual factors would be positively related to these same difficulties. To establish relationships, (...) we used a retrospective,ex postfacto design, where 298 university students voluntarily participated by completing standardized self-reports. Linear and structural correlational, predictive analyses were performed, as well as inferential analyses. Results were consistent and validated the proposed hypotheses, for both association and prediction. The most important result refers to the discriminant value of the five-level combination heuristic for predicting Executive Function and External (contextual) Dys-Regulation. In conclusion: (1) both personal and contextual regulation factors must be analyzed in order to better understand the variation in executive functions and emotion regulation difficulties; (2) it is important to continue connecting the different levels of the constructs referring to self-regulation, given their complementary role in the behavioral analysis of regulation difficulties.

A necessary condition for a group being taken as a rational agent is that its choices and judgements are ‘logically contestable’, but this can lead to problems of aggregation, as Arrow impossibility theorem or the discursive dilemma. This paper proposes a contractarian or constitutional approach: the relevant thing is what aggregation mechanisms would be preferred by the members of the group. Two distinctions need to be made: first, judgement aggregation is not aggregation of decisions, and judgement aggregation needs be distinguished (...) from the aggregation of information: we assume that every member of the group has already taken into account the opinions of the other members, by means of a process of public deliberation, but they may end having different opinions; we also assume that the members are rational, so that they have no reasons to accept further changes in their individual opinions. So, from the epistemic point of view, the collective judgment is not a 'better' opinion than those of the individual members. The collective judgement is better seen as a kind of compromise, the outcome of a ‘bargain’, so to say. Basically, we assume that individuals will have an interest in choosing a specific aggregation function by taking into account how are they affected by the collective actions carried out by the group, and grounded on the chosen collective judgement.

Using the approach known as ‘Economics of Scientific Knowledge’, this paper defends the view of scientific norms as the result of a ‘social contract’, i.e., as an equilibrium in the game of selecting the norms under which to proceed to play the game of scientific research and publication. A categorisation of the relevant types of scientific norms is offered, as well as a discussion about the incentives of the researchers in choosing some or other alternative rules.

Moulines’ arguments against several types of realism in his book Pluralidad y recursion are considered and a defence of scientific realism consistent with structuralism is offered as a plausible answer to Moulines’ criticisms.

In this paper I want to present the guiding lines of a research programme into the economics of scientific knowledge, a programme whose ultimate goal is to develop what I would like to call a contractarian epistemology. The structure of the paper is as follows: in the first section I will comment on two conflicting approaches to the topic of rationality in science: the view of the rationality of scientific knowledge as deriving from the employment of sound methodological norms, and (...) the view of scientists as rational agents pursuing the optimisation of their own personal and professional interests. In section 2 I will try to make both approaches mutually consistent by showing that a competition among rational "recognition-seekers" is only possible if they agree in accepting some system of methodological norms. Section 3 will be devoted to analyse the main kinds and properties of these norms. Finally, in section 4 I will discuss a question which is far from being easy and innocent: why are scientific norms obeyed by researchers, once they have been established in a scientific discipline?

BackgroundScientific literature on posttraumatic growth after terrorist attacks has primarily focused on persons who had not been directly exposed to terrorist attacks or persons who had been directly exposed to them, but who were assessed few months or years after the attacks.MethodsWe examined long-term PTG in 210 adults directly exposed to terrorist attacks in Spain a mean of 29.6 years after the attacks. The participants had been injured by a terrorist attack or were first-degree relatives of people who had been (...) killed or injured by a terrorist attack. They completed diagnostic measures of emotional disorders and measures of PTSD and depression symptomatology, optimism, and PTG.ResultsMultiple regression analyses revealed gender differences and a positive linear relationship between PTG and cumulative trauma after the terrorist attack. Some PTG dimensions were significantly associated with PTSD symptomatology, these associations being linear, not curvilinear. However, PTG was not associated with depression symptomatology, diagnosis of emotional disorders, age, elapsed time since the attack, or optimism. In comparison with survivors assessed 18 years after the 1995 Oklahoma City bombing, Spanish victims of terrorism showed higher levels of appreciation of life, but lower levels of relating to others and spiritual change.ConclusionThe findings underscore the influence of gender on PTG and provide support to the hypothesis that some emotional distress may be a necessary condition of PTG. Future studies on PTG after terrorist attacks should take into consideration the characteristics of the terrorist attack itself and the contexts of violence and threat in which it occurred. The political, social, and cultural characteristics of the community affected by it and the profile and characteristics of other traumatic events suffered after the attack should also be taken into account in further research.

Verisimilitude theorists (and many scientific realists) assume that science attempts to provide hypotheses with an increasing degree of closeness to the full truth; on the other hand, radical sociologists of science assert that flesh and bone scientists struggle to attain much more mundane goals (such as income, power, fame, and so on). This paper argues that both points of view can be made compatible, for (1) rational individuals only would be interested in engaging in a strong competition (such as that (...) described by radical sociologists) if they knew in advance the rules under which their outcomes are to be assessed, and (2), if these rules have to be chosen "under a veil of ignorance" (i.e., before knowing what specific theory each scientist is going to devise), then rules favoring highly verisimilar theories can be prefered by researchers to other methodological rules.

Recently, Rueger and Sharp (1996) and Koperski (1998) have been concerned to show that certain procedural accounts of model confirmation are compromised by non-linear dynamics. We suggest that the issues raised are better approached by considering whether chaotic data analysis methods allow for reliable inference from data. We provide a framework and an example of this approach.

Este artículo fue bom como lección inaugural del curso académico 1996-1997 en el Instituto de Estudios Teológicos de Sevilla (C.E.T). Se parte de una serie de notas biográficas del Padre Haring necesarias, según el autor, para comprender el desarrollo intelectual del personaje y la evolución de su enseñanza moral. En la segunda parte. La contribución del Padre Haring a la TeologíaMoral renovada se revela: una moral fundada sobre el Custodio de Dios; un nuevo destinatario, es decir, el paso del confesionario (...) al "cristiano adulto": paso de la ley y del mandamiento a la "ley del Espíritu que da la vida en Cristo": diálogo con el hombre de hoy: diálogo ecuménico: cultura continua, que implica renovación continua: moral de tendencia comunitaria (ni individualista, ni perfeccionista), de la solidaridad salvífica; moral que libera al hombre, que no lo aprisiona ni lo encorseta. En conclusion. se muestra claramente la gran aportación del Padre Haring a la Teología Moral: el paso de una moral centrada en el objeto a una moral centrada en el hombre libre, responsable y fiel a Cristo.
