The Price equation is currently considered one of the fundamental equations —or even the fundamental equation— of evolution. In this article, we explore the role of this equation within cultural evolutionary theory. More specifically, we use it to account for the explanatory power and the theoretical structure of a certain generalised version of dual-inheritance theory. First, we argue that, in spite of not having a definite empirical content, the Price equation offers a suitable formalisation of the processes of cultural evolution, (...) and provides a powerful heuristic device for discovering the actual causes of cultural change and accumulation. Second, we argue that, as a consequence of this, a certain version of the Price equation is the fundamental law of cultural evolutionary theory. In order to support this claim, we sketch the ideal structure of dual-inheritance theory and we stress the unificatory role that the Price equation plays in it. (shrink)

This paper provides a philosophical analysis of the Price equation and its role in evolutionary theory. Traditional models in population genetics postulate simplifying assumptions in order to make the models mathematically tractable. On the contrary, the Price equation implies a very specific way of theorizing, starting with assumptions that we think are true and then deriving from them the mathematical rules of the system. I argue that the Price equation is a generalization-sketch, whose main purpose is to provide a unifying (...) framework for researchers, helping them to develop specific models. The Price equation plays this role because, like other scientific principles, shows features as abstractness, unification and invariance. By underwriting this special role for the Price equation some recent disputes about it could be diverted. (shrink)

This article analyzes the view of evolutionary theory as a theory of forces. The analogy with Newtonian mechanics has been challenged due to the alleged mismatch between drift and the other evolutionary forces. Since genetic drift has no direction several authors tried to protect its status as a force: denying its lack of directionality, extending the notion of force and looking for a force in physics which also lacks of direction. I analyse these approaches, and although this strategy finally succeeds, (...) this discussion overlooks the crucial point on the debate between causalists and statisticalists: the causal status of evolutionary theory. (shrink)

This paper analyses the structure of evolutionary theory as a quasi-Newtonian theory and the need to establish a Zero-Cause Law. Several authors have postulated that the special character of drift is because it is the default behaviour or Zero-Cause Law of evolutionary systems, where change and not stasis is the normal state of them. For these authors, drift would be a Zero-Cause Law, the default behaviour and therefore a constituent assumption impossible to change without changing the system. I defend that (...) drift's causal and explanatory power prevents it from being considered as a Zero-Cause Law. Instead, I propose that the default behaviour of evolutionary systems is what I call the Principle of Stasis, which posits that an evolutionary system where there is no selection, drift, mutation, migration, etc., and therefore no difference-maker, will not undergo any change (it will remain in stasis).

Due to its high degree of complexity and its historical nature, evolutionary biology has been traditionally portrayed as a messy science. According to the supporters of such a view, evolutionary biology would be unable to formulate laws and robust theories, instead just delivering coherent narratives and local models. In this article, our aim is to challenge this view by showing how the Price equation can work as the core of a general theoretical framework for evolutionary phenomena. To support this claim, (...) we outline some unnoticed structural similarities between physical theories and evolutionary biology. More specifically, we shall argue that the Price equation, in the same way as fundamental formalisms in physics, can serve as a heuristic principle to formulate and systematise different theories and models in evolutionary biology.

In this paper, we address the question whether a mechanistic approach can account for evolutionary causes. The last decade has seen a major attempt to account for natural selection as a mechanism. Nevertheless, we stress the relevance of broadening the debate by including the other evolutionary causes inside the mechanistic approach, in order to be a legitimate conceptual framework on the same footing as other approaches to evolutionary theory. We analyse the current debate on natural selection as a mechanism, and (...) extend it to the rest of the evolutionary causes. We focus on three approaches that we call the stochastic view, the functional view, and the minimalist view. We argue that all of them are unable to account for evolutionary causes as mechanisms. It is concluded that the current mechanistic proposals cannot be accepted as a common framework for evolutionary causes. Finally, we outline some guidelines and requirements that any mechanistic proposal should meet in order to be applied to evolutionary theory. (shrink)

The aim of the present study was to determine statistical differences in a set of badminton competition matches in five different modalities with regard to competition level (Group Phase versus Eliminatory Phase). Data from 453 sets (125 in men’s singles; 108 sets in women’s singles; 77 sets in men’s doubles; 73 in women’s doubles and 70 in mixed doubles) from the RIO 2016 Olympics Games were recorded and classified in two groups of variables to analyse variables related to match (5) (...) and set (15). A descriptive analysis and univariate test (Mann Whitney U) for non-parametric data were conducted. The results show in men’s and women’s singles all the variables related to match were higher in the Elimination Phase than in the Group Phase (p<0.01). In Sets 1 and 3, the longest set duration, rally and average rally were found in the Elimination Phase than Group Stage (p<0.05). In women’s singles, these differences were also recorded in Set 2. For doubles, the results are more stable among groups. Men’s doubles had a longer duration of the match and set (set 1 and set 2) (p<0.01), and also scored highest for average rally strokes (set 1 and set 3) (p<0.05) and shuttles used in the Elimination Phase versus the Group Phase along the match (p<0.01). In women’s doubles, more shuttles were used in a match in the Elimination than in the Group Phase. Moreover, the same results are established for Set 2, including for average rally. Mixed doubles saw no match going to three sets. However, the greatest differences showed a longer rally and average rally being registered in the Elimination than in the Group Phase. In conclusion, the timing factors of the badminton singles and doubles games were different in the Elimination and Group Phases. This information may help players and coaches prepare and administer different types of workouts or, more specifically, competition schedules adapted to the characteristics of modern badminton.

a recent paper, Fábio Perin Shecaira proposes a defence of Waller’s deductivist schema for moral analogical argumentation. This defence has several flaws, the most important of them being that many good analogical arguments would be deemed bad or deficient. Additionally, Shecaira misrepresents my alternative account as something in between deductivism and non-deductivism. This paper is both an attempt at solving this misunderstanding and an analysis and criticism of Waller and Shecaira’s forms of deductivism.

Our aim is to defend the Precautionary Principle (PP) against the main theoretical and practical criticisms that it has raised by proposing a novel conception and a specific formulation of the principle. We first address the theoretical concerns against the idea of there being a principle of precaution by arguing for a distinctively political conception of the PP as opposed to a moral one. Our claim is that the rationale of the PP is grounded in the fact that contemporary societies (...) wish to avoid morally unacceptable risks while at the same time pursuing other goals, aspirations and values. Following this political conception of the PP, we propose a specific formulation in terms of an argumentation scheme—the Argumentation Scheme for Appealing to Precaution—which is meant to solve, in turn, the main practical concerns that the PP has raised. We explain the advantages of our proposal by analysing appeals to precaution in the cases of (1) the European restrictions on the free movement of persons during the COVID-19 pandemic and (2) the discharge of nuclear wastes into the Irish Sea.

I argue for the distinction between presuming that p and maintaining that presumably p. In order to make sense of this distinction, I defend a non-inferentialist conception of presumptions and offer an account of the correctness conditions for both presumptions and presumptive inferences. I characterize presumptions as a type of constative speech-act having certain semantic correctness conditions. In turn, regarding presumptive inferences, my strategy is to provide the correctness conditions for the use of an epistemic modal such as “presumably.” This (...) epistemic modal is characterized as a force indicator for speech-acts of concluding in complex speech-acts of arguing involving presumptive inferences.

In The Uses of Argument, Toulmin proposed a distinction between fielddependent and field-invariant standards for argument appraisal that gave rise to a relativistic understanding of his theory. The main goal of this paper is to show that epistemological relativism is not a necessary consequence ofToulmin's model of argument. To this end, I will analyze the role that fields are to play within this model, given a certain conception of one of its key elements: the warrant of an argument.

Following a Toulmian account of argument analysis and evaluation, I offer a general unitary schema for, so called, deductive and inductive types of analogical arguments. This schema is able to explain why certain analogical arguments can be said to be deductive, and yet, also defeasible.

Both because of the vagueness of the word ‘give’ when speaking about giving reasons, and because we lack an adequate definition of ‘reasons’, there is a harmful ambiguity in the expression ‘giving reasons’. Particularly, straightforwardly identifying argumentation with reasons giving would make of virtually any interplay a piece of argumentation. Besides, if we adopt the mainstream definition of reasons as “considerations that count in favour of doing or believing something”, then only good argumentation would count as argumentation. In this paper, (...) I defend a qualified characterization of argumentation as reasons giving that is shown to be fruitful for shedding light on the practice of giving reasons, and an inferentialist conception of reasons that makes room for speaking of “bad reasons” and, consequently, makes it possible to talk of argumentation as reasons giving even if we are talking about bad argumentation.

I characterize the deductivist ideal of justification and, following to a great extent Toulmin’s work The Uses of Argument, I try to explain why this ideal is erroneous. Then I offer an alternative model of justification capable of making our claims to knowledge about substantial matters sound and reasonable. This model of justification will be based on a conception of justification as the result of good argumentation, and on a model of argumentation which is a pragmatic linguistic reconstruction of Toulmin’s (...) model of argument.

Immédiates, efficaces et inépuisables comme des sensations, mais indépendantes du dehors et maîtresses de l’espace comme des images, les visions «imaginatives» de Thérèse, pour voisines qu’elles soient de nos visions sensorielles, méritent pourtant une place à part et ne sont ni des hallucinations vulgaires, indiscernables des sensations, ni des hallucinations psychiques. Ce sont les hallucinations thérésiennes. (Pierre Quercy 1930).

En el presente trabajo se abordará el Nuevo Realismo, movimiento filosófico que cada vez goza de mayor popularidad. En primer lugar, se hará un breve análisis de su origen. A continuación, se atenderá a las propuestas de cuatro de los principales referentes de este movimiento: Quentin Meillassoux, Graham Harman, Maurizio Ferraris y Markus Gabriel. El objetivo de esto es encontrar las semejanzas y diferencias entre todas, para poder establecer una clasificación más acertada dentro del nuevo realismo.

I defend a conception of Logic as normative for the sort of activities in which inferences super-vene, namely, reasoning and arguing. Toulmin’s criticism of formal logic will be our framework to shape the idea that in order to make sense of Logic as normative, we should con-ceive it as a discipline devoted to the layout of arguments, understood as the representations of the semantic, truth relevant, properties of the inferences that we make in arguing and reason-ing.

In “Deductivism as an Interpretative Strategy: A Reply to Groarke’s Defense of Reconstructive Deductivism,” David Godden distinguished two notions of deductivism. On the one hand, as an interpretative thesis, deductivism is the view that all-natural language argumentation must be interpreted as being deductive. On the other hand, as an evaluative thesis, deductivism is the view that for a conclusion to follow, it has to follow of necessity from the premises—or, in other words, that being a good inference implies being deductive. (...) The main goal of this paper is to show that evaluative deductivism is wrong. (shrink)

I argue that conductions are a special type of inference indeed, but that this does not mean that we need to develop novel standards of inference goodness or specific argument schemes for properly assessing them. Following LNMA’s theoretical framework, I provide a semantic account of conductions and explain the interesting pragmatic properties of a certain type of conductions in terms of the rhetorical dimension of the speech-act of arguing.

. There are many types of artistic representations of the legend of Don Juan, i.e. the universal archetype of the seducer who, through deception, conquers a woman and, once she succumbs to his charms, he boasts of his triumph, despises her, and shifts his interest towards another lady. In this work, I compare three of the most famous versions don Juan: The Trickster of Seville and the Stone Guest by Tirso de Molina, Don Giovanni by Wolfgang Amadeus Mozart and Lorenzo (...) Da Ponte, and Don Juan Tenorio by José Zorrilla. The first and third are theatrical pieces, while the second is an opera. The myth of Don Juan is essentially the same in all three, but the message and the moral vary according to the cultural movement the works belong to, namely the Baroque, the Enlightenment and the Romanticism, respectively. Key words: The Trickster of Seville and the Stone Guest, Don Giovanni, Don Juan, Tirso de Molina, Wolfgang Amadeus Mozart, Lorenzo Da Ponte, José Zorrilla, sin, redemption, sociopath. Resumen. Son muchos los tipos de representación artística —teatro, música, ópera, ballet, literatura, cine, televisión, pintura, escultura, etc.— de la leyenda de Don Juan, el arquetipo universal del seductor que, mediante engaños, conquista a una mujer y, una vez que ella sucumbe a sus encantos, se jacta de su triunfo, las desprecia y reenfoca su interés en otras damas. En este trabajo, comparo a tres de los don Juanes más famosos: El burlador de Sevilla y convidado de piedra de Tirso de Molina, Don Giovanni de Wolfgang Amadeus Mozart y Lorenzo Da Ponte, y Don Juan Tenorio de José Zorrilla. La primera y la tercera son piezas teatrales, en tanto que la segunda es una ópera. El mito de Don Juan es, esencialmente, el mismo en estas tres obras, aunque varían el mensaje y la moraleja según el movimiento cultural al que pertenecen: Barroco, Ilustración y Romanticismo, respectivamente. Palabras clave: Burlador de Sevilla, Don Giovanni, Don Juan, Tirso de Molina, Wolfgang Amadeus Mozart, Lorenzo Da Ponte, José Zorrilla, pecado, redención, sociópata. (shrink)

Resumen Este ensayo analiza la manera tan negativa en que Emilia Pardo Bazán representa al matrimonio en Los pazos de Ulloa. Se intenta mostrar que el escepticismo de la autora, al presentar esta institución social como un proyecto fallido, constituye una protesta feminista contra la soflama masculina hegemónica del siglo xix, que aceptaba como válido únicamente el vínculo conyugal bendecido por la Iglesia y/o sancionado por el Estado. Con este objetivo, se estudian algunos factores que afectaban las relaciones maritales de (...) las mujeres de aquella época, tales como la percepción que se tenía de la mujer—como agente civilizador y como inductora del mal—, las expectativas sociales de la mujer casadera y casada, el alto valor atribuido a la virginidad prenupcial y a la maternidad, la doble moral en el ejercicio de la sexualidad, la subordinación de la mujer al hombre y la violencia doméstica física y mental. Palabras clave: Los pazos de Ulloa, Emilia Pardo Bazán, virginidad, maternidad, matrimonio, civilización y barbarie.In this essay, I analyze Emilia Pardo Bazán's negative portrait of marriage in The House of Ulloa. I attempt to show that the author's skepticism of this social institution, which she presents as a failed project, is a feminist protest against the 19thcentury hegemonic masculine discourse that considered Catholic marriage and/or legal marriage as the only acceptable forms of a conjugal bond. With that intention, I comment on several key factors that affected women’s marital relationships at that time. For example, the dual perception of women both as civilizing agents and as a temptation to sin and subsequent perdition, the social expectations from a maiden and from a married woman, the high value attributed to prenuptial virginity and of maternity, the double standards for men and women in the expression of their sexuality, the subordination of women to men, and domestic physical and mental violence, among other.

Technical and tactical actions are decisive in terms of badminton player competitive performance. The main objective of this research was to design, validate, and estimate the reliability of an observational instrument for the analysis of the tactical and technical actions in individual badminton. The process was carried out in four different steps: first, there was a review of the scientific literature and a preliminary list of variables was made; second, a qualitative and quantitative assessment was completed by 10 badminton expert (...) judges; in the third step, the content validity was estimated using Aiken’s V coefficient; finally, intra-observer reliability and interobserver reliability were tested by two observers specialized in badminton using the Cohen’s Kappa coefficient and the intraclass correlation coefficient. Strokes were used as the unit of measure by our observational instrument; every time badminton players hit the shuttlecock, 22 variables are observed. The minimum Aiken’s value was 0.58, and reliability was 0.63. In spite of these values, none of the variables had to be removed, but there were modifications in terms of drafting in some of them. The main findings confirmed the validity and the usefulness of this instrument. (shrink)

The present article delves into the extension of Knuth’s fundamental Boolean logic table to accommodate the complexities of indeterminate truth values through the integration of neutrosophic logic (Smarandache & Christianto, 2008). Neutrosophic logic, rooted in Florentin Smarandache’s groundbreaking work on Neutrosophic Logic (cf. Smarandache, 2005, and his other works), introduces an additional truth value, ‘indeterminate,’ enabling a more comprehensive framework to analyze uncertainties inherent in computational systems. By bridging the gap between traditional boolean operations and the indeterminacy present in various (...) real-world scenarios, this extension redefines logic tables, introducing neutrosophic operators that capture nuances beyond the binary realm. Through a thorough exploration of neutrosophic logic's principles and its implications in computational paradigms, this study proposes a novel approach to logic design that accommodates uncertain, imprecise, and incomplete information. This paradigm shift in logic tables not only broadens the spectrum of computing methodologies but also holds promise in fields such as decision-making systems and data analytics. This article amalgamates insights from over twelve key references encompassing seminal works in boolean logic, neutrosophic logic, and their applications in diverse scientific and computational domains, aiming to pave the way for a more robust and adaptable logic framework in computation.

I provide responses to what I take to be the most salient aspects of John Biro, James Freeman, David Hitchcock, Robert Pinto, Harvey Siegel and Luis Vega’s criticisms to the normative model for argumentation that I have developed in Giving Reasons. Each response is articulated on a main question, i.e., the distinction between regulative and constitutive normativity within Argumentation Theory’s models, the semantic appraisal of argumentation, the concept of justification, the differences between Toulmin’s model and my model of argument and (...) the analysis of the pragmatic dimension of argumentation.

How should automated vehicles react in emergency circumstances? Most research projects and scientific literature deal with this question from a moral perspective. In particular, it is customary to treat emergencies involving AVs as instances of moral dilemmas and to use the trolley problem as a framework to address such alleged dilemmas. Some critics have pointed out some shortcomings of this strategy and have urged to focus on mundane traffic situations instead of trolley cases involving AVs. Besides, these authors rightly point (...) out the political nature of the most interesting debates involving AVs. However, in our view, they do not offer an adequate account of the distinction between ethics and politics and still see their proposals as contributions to the ethics of AVs. We argue that many of the interesting questions about how AVs should behave, both in emergency and other situations, are of political, and not moral, nature. This view is based on a conception of politics and political normativity that we have developed elsewhere and that we call “political minimalism.” Additionally, we show that this proposed perspective has significant consequences for the design, management, and regulation of transport systems.

I propose a characterization of the dialectical dimension of argumentation by considering the activity of arguing as involving a “second order intersubjectivity”. I argue that argumentative communication enables this kind of intersubjectivity as a matter of the recursive nature of acts of arguing—both as justificatory and as persuasive devices. Calling attention to this feature is a way to underline that argumentative discourses represent the explicit part of a dynamic activity, “a mechanism of rational validation”, as Rescher showed, which is a (...) practice that presupposes the possibility of attaining objectivity.

For long time, especially in the West, there is old paradigm that is strong separation between science and theology/religion matters. Especially, such a diverging path started from Galileo persecution, and also other patterns where religious authority seem to hold the last word on scientific issues. Other area of this World, seems to not hold such a diverging path, for instance it can be read in the works of physicist turned to religious philosopher, for instance Pavel Florensky and Nesteruk. That is (...) why we also discuss shortly about those scientists in this book. In the last chapter, we discuss about eureka, an experience which for a long time was attributed to divine spark or “God’s favor to an artist or to a scientist, such luminaries like Newton, Pascal, Leibniz etc.” Nonetheless, new methodology appears to be able to be generated once we accept balanced brain approach, where left brain and right brain hemispheres of humans can work together.

As such "Essay on Exoticism" is essential reading for both cultural theorists or those with an interest in the politics of difference and diversity.

According to political minimalism, a debate is considered political when it revolves around the question “What shall we do?” This account suggests that certain issues related to human enhancement technologies (HETs), which have traditionally been addressed in the realm of applied ethics, could be better approached from a political standpoint. However, this raises the question of who constitutes the “we” – the communities that face the political challenges posed by HETs. We argue that there is a global human community that (...) directly faces at least some of these challenges, and this fact underscores the relevance of a cosmopolitan perspective. While some authors have already advocated for a cosmopolitan approach in addressing issues such as poverty or climate change, they often do so from a moral outlook, without adequately distinguishing between ethics and politics. In contrast, we assert that HETs present compelling arguments in favour of cosmopolitanism as a political stance. In support of this claim, we consider two cases: the pills that would allow people to eat at will without gaining weight, and the choice between different types of cognitive enhancers. (shrink)

In some recent papers (G. ‘t Hooft and others), it has been argued that quantum mechanics can arise from classical cellular automata. Nonetheless, G. Shpenkov has proved that the classical wave equation makes it possible to derive a periodic table of elements, which is very close to Mendeleyev’s one, and describe also other phenomena related to the structure of molecules. Hence the classical wave equation complements Schrödinger’s equation, which implies the appearance of a cellular automaton molecular model starting from classical (...) wave equation. The other studies show that the microworld is constituted as a tessellation of primary topological balls. The tessellattice becomes the origin of a submicrospic mechanics in which a quantum system is subdivided to two subsystems: the particle and its inerton cloud, which appears due to the interaction of the moving particle with oncoming cells of the tessellattice. The particle and its inerton cloud periodically change the momentum and hence move like a wave. The new approach allows us to correlate the Klein-Gordon equation with the deformation coat that is formed in the tessellatice around the particle. The submicroscopic approach shows that the source of any type of wave movements including the Klein-Gordon, Schrödinger, and classical wave equations is hidden in the tessellattice and its basic exciations – inertons, carriers of mass and inert properies of matter. We also discuss possible correspondence with Konrad Zuse’s calculating space. (shrink)

The deductivist ideal of justification is bounded to scepticism respecting the trustability of reasoning. This ideal is supported by a conception of formal validity as a necessary condition for argumentative goodness. In this work, I propose an alternative to formalism in order to make sense of the idea of justification out of the scope of the deductivist ideal.

In Giving Reasons: A Linguistic-pragmatic-approach to Argumentation Theory (Springer, 2011), I provide a new model for the semantic and pragmatic appraisal of argumentation. This model is based on a characterization of argumentation as a second order speech-act complex. I explain the advantages of this model respecting other proposals within Argumentation Theory, such as Pragma-dialectics, Informal Logic, the New Rhetoric or the Epistemic Approach.

¿Por qué está mal hacer una petición de principio, formular una pregunta compleja, desplazar la carga de la prueba, crear un hombre de paja o usar lenguaje cargado? ¿En qué consiste el error argumentativo de las "falacias informales"? ¿Es siempre incorrecto argumentar ad hominem, ad populum, ad verecundiam? La lógica formal ha dejado estas preguntas sin respuesta, pues nunca ha sido su cometido indagar los entresijos pragmáticos de la argumentación cotidiana, más allá de las relaciones de inferencia. En cambio, a (...) la teoría de la argumentación le interesa todo aquello que forma parte del buen argumentar, incluido lo que la lógica no alcanza. Este libro es una introducción a la teoría de la argumentación, con especial atención al estudio de las falacias informales. En él se exponen los modelos más influyentes para la distinción entre buena y mala argumentación, y se discute si alguna teoría de la falacia podría servir como modelo para evaluar argumentos. Se analiza también la función del catálogo tradicional de falacias, la distinción entre malos argumentos y argumentos falaces, la posibilidad de desarrollar una teoría de la falacia digna de ese nombre e, incluso, la coherencia del concepto mismo de falacia.
