Category-based induction is an inferential mechanism that uses knowledge of conceptual relations in order to estimate how likely is for a property to be projected from one category to another. During the last decades, psychologists have identified several features of this mechanism, and they have proposed different formal models of it. In this article; we propose a new mathematical model for category-based induction based on distances on conceptual spaces. We show how this model can predict most of the properties of (...) this kind of reasoning while providing a solid theoretical foundation for it. We also show that it subsumes some of the previous models proposed in the literature and that it generates new predictions. (shrink)

In Gärdenfors and Makinson :197–245, 1994) and Gärdenfors it was shown that it is possible to model nonmonotonic inference using a classical consequence relation plus an expectation-based ordering of formulas. In this article, we argue that this framework can be significantly enriched by adopting a conceptual spaces-based analysis of the role of expectations in reasoning. In particular, we show that this can solve various epistemological issues that surround nonmonotonic and default logics. We propose some formal criteria for constructing and updating (...) expectation orderings based on conceptual spaces, and we explain how to apply them to nonmonotonic reasoning about objects and properties.

In this paper, we outline a comprehensive approach to composed analogies based on the theory of conceptual spaces. Our algorithmic model understands analogy as a search procedure and builds upon the idea that analogical similarity depends on a conceptual phenomena called ‘dimensional salience.’ We distinguish between category-based, property-based, event-based, and part-whole analogies, and propose computationally-oriented methods for explicating them in terms of conceptual spaces.

In this article I am going to reconstruct Stephen Toulmin’s procedural theory of concepts and explanations in order to develop two overlooked ideas from his philosophy of science: methods of representations and inferential techniques. I argue that these notions, when properly articulated, could be useful for shedding some light on how scientific reasoning is related to representational structures, concepts, and explanation within scientific practices. I will explore and illustrate these ideas by studying the development of the notion of instantaneous speed (...) during the passage from Galileo’s geometrical physics to analytical mechanics. At the end, I will argue that methods of representations could be considered as constitutive of scientific inference; and I will show how these notions could connect with other similar ideas from contemporary philosophy of science like those of models and model-based reasoning.

Generic statements play a crucial role in concept learning, communication and education. Despite many efforts, the semantics of generics remain a controversial issue, as they do not seem to fit our standard theories of meaning. In this article, we attempt to shed light on this problem by focusing on how these sentences function in reasoning. Drawing on a distinction between property and diagnostic generics, we defend three theses: First, property generics are not about facts but express relations between concepts. Second, (...) generics play an important role in everyday reasoning by interacting with our expectations about the world. Third, diagnostic generics emphasise properties that separate the category in the generics from other categories in the same contrast class. We use the theory of conceptual spaces to advance measures of typicality and diagnosticity capable of modelling different aspects of generics and apply them to the modifier effect and the inverse conjunction fallacy. Finally, we discuss the pragmatics of generics. (shrink)

Over the past few decades, cognitive science has identified several forms of reasoning that make essential use of conceptual knowledge. Despite significant theoretical and empirical progress, there is still no unified framework for understanding how concepts are used in reasoning. This paper argues that the theory of conceptual spaces is capable of filling this gap. Our strategy is to demonstrate how various inference mechanisms which clearly rely on conceptual information—including similarity, typicality, and diagnosticity-based reasoning—can be modeled using principles derived from (...) conceptual spaces. Our first topic analyzes the role of expectations in inductive reasoning and their relation to the structure of our concepts. We examine the relationship between using generic expressions in natural language and common-sense reasoning as a second topic. We propose that the strength of a generic can be described by distances between properties and prototypes in conceptual spaces. Our third topic is category-based induction. We demonstrate that the theory of conceptual spaces can serve as a comprehensive model for this type of reasoning. The final topic is analogy. We review some proposals in this area, present a taxonomy of analogical relations, and show how to model them in terms of distances in conceptual spaces. We also briefly discuss the implications of the model for reasoning with concepts in artificial systems. (shrink)

ABSTRACT Gareth Evans and Sven Rosenkranz have respectively formulated two objections to truth relativism that would show that this view does not cohere with our practice of asserting. I argue that the relativist should answer such objections by appealing to the notion of assessment sensitivity. Since the relativist accounts for this notion by means of a technical truth predicate relating propositions to contexts of assessment, the task left to her turns out to be to make sense of assessment sensitivity by (...) making sense of this predicate. RESUMO Gareth Evans e Sven Rosenkranz formularam, respectivamente, duas objeções ao relativismo da verdade que mostrariam que esta visão não é coerente com nossa prática de afirmar. Defendo que o relativista deve responder a tais objeções apelando à noção de sensibilidade da avaliação. Tendo em mente que o relativista considera essa noção por meio de um predicado de verdade técnica, a tarefa deixada para ele calha de ser dar sentido à sensibilidade da avaliação mediante dar sentido a esse predicado.

En las últimas dos décadas, la relación directa o indirecta de Kierkegaard con la nueva fenomenologíase ha vuelto un tópico de creciente interés. Haciendo eco de este ánimo, en este artículo pretendo leerdos niveles del pensamiento de Kierkegaard a partir de las directrices generales de la nuevafenomenología. El primer estadio refiere al carácter descentrado del sujeto kierkegaardiano frente aDios, modulación que se entrelaza con una inversión de la intencionalidad husserliana. Por otro lado,el segundo escalón apunta a la intersubjetividad, en tanto (...) el reconocimiento de y la responsabilidadhacia los otros. El objetivo es mostrar que Kierkegaard contribuye al proyecto de la nuevafenomenología no sólo como un crítico más de la metafísica moderna, sino también como proveedorde categorías reconstructivas del individuo y la comunidad.

Este trabajo parte de la pregunta por la posibilidad de deducir un planteamiento estrictamente político de los análisis ontológicos de la modernidad llevados a cabo por Martin Heidegger. Con este fin, se examina su interpretación del fenómeno griego de la pólis, así como la distinción que en ella se establece entre esta forma de comunidad y el Estado moderno, fundado para Heidegger en la esencia metafísica de la modernidad. Para clarificar esta cuestión se atiende a la proclamación de valores que (...) Heidegger observa en los diferentes modos de organización estatal que aparecen en la época de la consumación técnica de la metafísica. En conexión con ello, se estudia su visión del nihilismo y se ofrece finalmente una hipótesis sobre la forma de Estado que resultaría coherente con la renuncia a los valores que, a su juicio, exige la manifestación del ente en la modernidad como objeto por entero producible.

The crisis resilience of vital social systems is currently the target of constant development efforts in Finland, as their drifting into crisis would weaken societies’ functional abilities, safety, and security. This is also the case regarding the Finnish health care system. In an attempt to move beyond existing frameworks of crisis imagination, this article takes an unconventional stance by elucidating endogenous crisis dynamics present in the Finnish health care system. Delphi process was conducted for top experts in Finnish health care (...) and crisis management. With a dissensus-seeking orientation, our aim was to fertilize disagreements among panelists to reveal key vulnerabilities in the health system. Despite our efforts to evoke dissensus, the panelists ended up generating a consensus that aims to protect the underlying assumptions of the health system’s knowledge structure. Through inductive analysis of expert discourses, the data was analyzed through our research question “what constitutes a crisis-proof health system and a crisis-prone health system”. What is framed as a strength of the system by our panelists, namely the ability to maintain legitimacy, improve efficiency, and guarantee continuity, can still have questionable implications that are left ungrasped. A system’s theory approach illustrates how such effects can develop and escalate beyond the reach of social interventions, and thus be predisposed to cause objectionable yet concealed social crises. The discussion illustrates how these endogenous crisis dynamics could be seen to materialize in real-life cases. (shrink)

This article centers on Hume’s position on the intelligibility of natural philosophy. To that end, the controversy surrounding universal gravitation shall be scrutinized. It is very well-known that Hume sides with the Newtonian experimentalist approach rather than with the Leibnizian demand for intelligibility. However, what is not clear is Hume’s overall position on the intelligibility of natural philosophy. It shall be argued that Hume declines Leibniz’s principle of intelligibility. However, Hume does not eschew intelligibility altogether; his concept of causation itself (...) stipulates mechanical intelligibility. (shrink)

La dirección de Nemesio Antúnez entre 1962 y 1964, y las administraciones que le siguieron en el Museo de Arte Contemporáneo (MAC), son un caso ejemplar de las dinámicas político-culturales desarrolladas durante la Guerra Fría. Este artículo analiza esta gestión museal desde la historia intelectual y la historia cultural, trabajando las redes de pensamiento que rodearon a Antúnez y la disquisición entre su programación y la influencia norteamericana en ese momento, atendiendo a cómo el MAC se involucró en la guerra (...) fría cultural. De esta manera se busca aportar al conocimiento de las tramas institucionales que se dieron entre la intelectualidad periférica y los centros metropolitanos durante uno de los periodos claves del siglo XX, presentando ciertos programas expositivos que respondieron al impulso de los EE. UU. de inserción ideológica. (shrink)

In this paper, I aim to show the evolution of Kierkegaard’s views on the state scattered in his Papers. To do this, I will carry out an analysis divided into chronological periods, and I will characterize each period in terms of its main features. The goal is to give a comprehensive account of Kierkegaard as a champion of the monarchical and authoritative state, who loses his patience and attacks the established order only when he thinks that Christianity’s truth is at (...) the greatest risk. This interpretation contrasts both with a mere despotic Kierkegaard and with a more liberal one. (shrink)

El presente trabajo reflexiona sobre el pensamiento de la comunidad en Giorgio Agamben y Roberto Esposito. Ambos interrogan lo común desde una perspectiva impolítica que intenta deconstruir los presupuestos de la metafísica y de la filosofía política tradicionales para poder elaborar una conceptualidad afirmativa en clave ontológica. En estos autores predomina el recurso a la figura de la comunidad, situada luego en el horizonte de la biopolítica, ya que la vida deviene el centro hacia el cual apuntarían los dispositivos de (...) poder y las formas de subjetivación política actuales. El trabajo plantea como interrogante si estos abordajes ontológicos logran dar cuenta plenamente de lo común en términos políticos o sólo éticos. (shrink)

McTaggart famously introduced the A- and B-series as rival metaphysical accounts of time. This paper shall reorient the debate over the original distinction. Instead of treating the series as competing theories about the nature of time, it will be argued that they are different viewpoints on a world that is fundamentally physical. To that end, non-reductive physicalism is proposed to reconcile the series.

Se investiga la metodología estructural deHistoire de la folie à l’ageclassique. Se sos- tiene que Michel Foucault, a partir de los trabajos de George Dumézil, elabora el concepto de experiencia para dar fundamento a las diversas experiencias históricas de la locura. La experiencia epocal, desarrollada en aquel texto, apela a una causalidad estructural que proviene del esquema de la trifuncionalidad ideológica indoeuropea de las obras de Dumézil.

I examine an intuitive property of folk-psychological explanations I call self-sufficiency. I argue that individualism cannot honor this property and work toward distilling an account of psychological explanation that does honor it, given some fairly standard assumptions. In doing so, my preference for an Externalist individuation of intentional state will emerge unambiguously. The assumptions I rely on are fairly standard but not uncontroversial. Yet not always do I attempt to defend them from objections. My goal is an account of folk (...) psychology consistent with our every-day practices rather than the deduction of an idealized psychology from first principles. I conclude with some applications offered as evidence that the goal was achieved. (shrink)

Controversy has reigned for some time over the biological connection between DNA methylation and cancer. For this reason, the methylation mechanism responsible for increased cancer risk has received greater attention in recent years. Tumor suppressor genes are often hypermethylated resulting in gene silencing. Although some have questioned this interpretation of the link between methylation and cancer, it appears that both hypermethylation and hypomethylation events can create epigenetic changes that can contribute to cancer development. Recent studies have shown that the methyltransferases (...) DNMT1 and DNMT3b cooperatively maintain DNA methylation and gene silencing in human cancer cells. Disruption of the human DNMT3b only slightly reduces the overall global DNA methylation; however, demethylation was markedly potentiated when both DNMT1 and DNMT3b were simultaneously deleted. The results to these experiments provide compelling evidence towards a role for DNA methylation in cancer. This review discusses the current understanding of cancer‐epigenetic information and highlights recent studies that connect the methylation machinery and chromatin remodelling with cancer susceptibility.

La principal objeción contra al dualismo cartesiano en filosofía de la mente es que resulta incompatible con la ciencia. Se sostiene, en particular, que el principio de clausura causal del mundo físico y el teorema de preservación de la energía, así como el concepto de interacción dinámica de la física fundamental, desautorizan la postulación de interacciones causales entre sustancias pensantes y sustancias extensas. En este trabajo sostengo que esta conclusión es por lo menos apresurada y que no es un asunto (...) trivial refutar el dualismo cartesiano usando consideraciones empíricas. Mis tesis son: (i) que las críticas antidualistas basadas en premisas científicas colapsan en un reduccionismo metafísicamente implausible y (ii) que la teoría física no excluye la existencia de una relación de causación o interacción dinámica recurrente como la que se requiere para explicar la experiencia consciente, postulando un nexo pertinente entre mentes inmateriales y sistemas nerviosos.

This paper proposes to give a brief overview of the state of contemporary Ecuadorian art. The first section defines the concept and practice of contemporary art in relation to ethics and truth. The second section deals with "problems" that beset the creators, curators and art critics, art market, and consumers, makes a brief allusion to the state of higher education in arts. In this section, although it emphasizes the fragility of Ecuadorian contemporary art, also noted that each of the states (...) mentioned as an opportunity to improve and advance, not only in development and positioning of Ecuadorian art, but above all, a world of art. At the conclusion emphasizes the necesariety to reduce the deformations presented in order to recover a primary and fundamental concept of art: "Art exists because there are works of art, and because these are artists, and because there is such a world of art.".

This article explores the motives underlying corporate responses to the COVID-19 pandemic. The analysis begins with Thomas Dunfee’s Statement of Minimum Moral Obligation (SMMO), which specifies, more precisely than any other contribution to the business ethics canon, the level of corporate beneficence required during a pandemic. The analysis then turns to Milton Friedman’s neoliberal understanding of human nature, critically contrasting it with the notion of stoic virtue that informs the works of Adam Smith. Friedman contends that beneficence should play no (...) role in corporate settings. Smith, by contrast, emphasizes the need for prudence, beneficence and self-command in all human endeavours. The article then uses these competing frameworks to reflect on a published survey of 145 corporate responses to COVID-19. In many of these responses, the benefit to a non-financial stakeholder is clear, while the financial consequence to the firm remains nebulous. This supports the contention that during a pandemic, beneficence provides a more complete explanation of many corporate actions than the profit motive alone. The article contests Friedman’s Chicago School profit imperative and goes beyond Dunfee’s SMMO by endorsing the more full-throated embrace of beneficence and stoic virtue found in the works of Smith.

A través del presente ejercicio investigativo y hermenéutico se busca proponer la beneficencia como principio articulador entre la Teología Moral de la Persona, la Bioética y las Prácticas Biomédicas, con el fin de salvaguardar al ser humano de forma integral y desde el ámbito interdisciplinar, frente a la manipulación y menoscabo de la persona en su: dignidad, status antropológico, verdad ontológica y trascendente, lo cual nos lleva a proponer alternativas, dadas las nuevas circunstancias por las que atraviesa la humanidad; y (...) es aquí donde adquiere resonancia proponer la Beneficencia como principio articulador entre estas tres ciencias, dado que ella, como principio, está en los tres saberes de forma implícita y explícita y, las cuales, por su misma esencia, tienen puntos de convergencia como son: la determinación de su carácter moral, su estatuto de servicio, la salvaguarda de la riqueza de la vida, el reconocimiento y respeto por la dignidad humana, el reconocimiento de la multidimensionalidad del ser, y el cuidado que requiere toda persona humana en su fragilidad y vulnerabilidad. Además de lo anterior se cuenta con un abordaje teórico sobre la bioética como saber interdisciplinar; los principios de la bioética y la relación de la teología moral de la persona con la bioética.

Giorgio Agamben and Ludwig Wittgenstein seem to have very little in common: the former is concerned with traditional ontological issues while the latter was interested in logics and ordinary language, avoiding metaphysical issues as something we cannot speak about. However, both share a crucial notion for their philosophical projects: form of life. In this paper, I try to show that, despite their different approaches and goals, form of life is for both a crucial notion for thinking ethics and life in-common. (...) Addressing human existence in its constitutive relation to language, this notion deconstructs traditional dichotomies like bios and zoé, the cultural and the biological, enabling both authors to think of a life which cannot be separated from its forms, recognizing the commonality of logos as the specific trait of human existence. Through an analogical reading between both theoretical frameworks, I suggest that the notion of form-of-life, elaborated by Wittgenstein to address human production of meaning, becomes the key notion in Agamben's affirmative thinking since it enables us to consider the common ontologically in its relation to Human potentialities and to foresee a new, common use of the world and ourselves. Giorgio Agamben e Ludwig Wittgenstein parecem ter muito pouco em comum: o primeiro se ocupa de questões ontológicas tradicionais, enquanto o segundo estava interessado na Lógica e na linguagem corrente, evitando os problemas metafísicos como algo de que não podemos falar. No entanto, ambos partilham um conceito crucial para seus projetos filosóficos respectivos: forma de vida. Este artigo tento mostrar que, apesar de seus diferentes enfoques e objetivos, a noção de forma de vida é fundamental no momento de pensar a ética e a vida em-comum. Abordando a existência humana em sua relação constitutiva com a língua, essa noção desconstrói dicotomias tradicionais como bios e zoe, o cultural e o biológico, permitindo-lhes pensar uma vida que não pode ser separada de suas formas, e reconhecendo o caráter comum do logos como o traço específico da existência humana. Através de uma leitura analógica entre ambos quadros teóricos, sugiro que a noção de forma-de-vida, elaborada por Wittgenstein para abordar a produção humana de significados, tornase o conceito-chave do pensamento afirmativo de Agamben, já que nos permite considerar o comum ontologicamente em sua relação com as potencialidades humanas e vislumbrar um uso novo e comum do mundo e de nós mesmos.

This article explores the strategic management of government affairs in companies active in the EU. The article relies on a unique large-N dataset on the functioning and staffing of EU government affairs. The analysis shows that companies delegate government affairs functions to in-house managers with specific competences, who stay in office for long periods and who have an extensive knowledge of the core competences of the company, thanks to their educational background and work experience in the private sector. These findings (...) suggest that how companies strategically manage and staff government affairs in Brussels rests on the distinct structure of business–government relations in the EU, which are based on the exchange of technical information and the establishment of credibility and long-run trust arrangements.

This study explores the legal and ethical issues associated with contract pricing. In particular, it focuses on a set of legal precedents which have addressed the enforceability of allegedly unfair contract prices. Traditionally, the common law has emphasized the consent of the parties. If the parties consented to a given price; it is presumptively fair and enforceable. The cases reviewed in this study, however, seem to draw upon alternative moral conceptions of fairness not normally associated with the common law. The (...) analysis begins by distinguishing the traditional legal conception of fairness from alternative moral conceptions. The cases are then read with a critical eye so as to tease out the underlying principles which best explain them. The analysis illustrates that, notwithstanding judicial rhetoric to the contrary, the courts continue to employ the traditional legal notion of fairness, to the exclusion of alternative moral concerns. The study clarifies an otherwise murky area of the law and illustrates that the legal meaning of fairness differs greatly from the moral one. (shrink)

Eternalism is the view that all times are equally real. The relativity of simultaneity in special relativity backs this up. There is no cosmically extended, self-existing ‘now.’ This leads to a tricky problem. What makes statements about the present true? I shall approach the problem along the lines of perspectival realism and argue that the choice of the perspective does. To corroborate this point, the Lorentz transformations of special relativity are compared to the structurally similar equations of the Doppler effect. (...) The ‘now’ is perspectivally real in the same way as a particular electromagnetic spectrum frequency. I also argue that the ontology of time licensed by perspectival realism is more credible in this context than its current alternative, the fragmentalist interpretation of special relativity.

The concept of “revolutionary myth” is the idea of Georges Sorel most influential in the thinking of José Carlos Mariátegui. However, this concept does not work the same way in both authors, mainly because it is applied in each case on markedly different national situations, such as France and Peru in the early twentieth century. For this reason it is important, regardless of the theoretical similarities, expressed as the difference between a general strike myth, linked to European industrial proletariat, and (...) another characterized around the social revolution, linked to the masses of the indigenous peasantry. In both cases we see that such concepts are functional to an extension of the limits of Marxism beyond Stalinism and the III International. (shrink)

En confrontación con las interpretaciones que asignan un significado religioso o teológico a las referencias a los dioses, a lo sagrado, o al “último dios” presentes en la obra de Martin Heidegger, este trabajo defiende una lectura en clave estrictamente ontológica de tales referencias. Para ello, se remite al diálogo que Heidegger mantiene con la poesía de Hölderlin y se argumenta que el significado que atribuye a la invocación hölderliniana a los “dioses huidos” depende del carácter ontológico que, en otro (...) contexto, concede a la nominación de los dioses característica del decir poético griego. Ese mismo carácter se pone de manifiesto en el sentido que, según Heidegger, ostenta la apelación a “lo sagrado” de la poesía de Hölderlin como nombre poético del ser en su despliegue histórico. Finalmente, dicha interpretación se hace extensiva a la figura del “último dios”, resaltando que su comprensión pasa por atender a la exégesis heideggeriana de la cuestión de la huida de los dioses en la obra poética de Hölderlin.

This article explores the law and ethics of lobbying. The legal discussion examines disclosure regulations, employment restrictions,bribery laws, and anti-fraud provisions as each applies to the lobbying context. The analysis demonstrates that given the social value placed on the First Amendment, federal law generally affords lobbyists wide latitude in determining who, what, when, where, and how to lobby.The article then turns to ethics. Lobbying involves deliberate attempts to effect changes in the law. An argument is advanced that because law implicates (...) the use of force and because law ideally reflects the values of a democratic society, seeking to slant the law to serve a client’s narrow interests cannot provide an adequate ethical end for a lobbyist. On the contrary, a lobbyist has an affirmative moral duty to seek reasonably balanced and just laws. The article examines, refines, and defends this proposition in a number of settings. (shrink)

In his article “La verdad y el éxito de la ciencia: A propósito de un artículo de P. Kyle Stanford” (2002), Manuel Comesaña addresses fundamental questions about the nature and success of science, taking P. Kyle Stanford’s article as a reference for his critical analysis. Although the central focus of both works is not specifically on the Copernican Revolution, it is relevant to analyse how both authors use this historical example from astronomy to illustrate their metaphysical commitments. Rigorous analysis of (...) this historiographical episode will provide better foundations for the broader discussion of the realism-anti-realism debate. It is for this reason that we will undertake a critical study and subsequent correction of the way in which both authors set up their accounts to exemplify their positions. What we have come to contribute with our commentary is not a position that attempts to account for the success of the anti-realist proposals that the authors are interested in debating, but rather we intend to shed light on the treatment given to the historical case in order to clarify certain obscure points in the debate.

Eternalism is a metaphysical view regarding the nature of time. It posits the equal existence of all times: the past, the present, and the future. Every event, from the big bang to the heat death of the universe, including our births and deaths, is equally real. -/- Under standard eternalism, temporal locations are somewhat akin to spatial locations. No place is exclusively real. When someone says that they stand ‘here’, it is clear that the term ‘here’ refers to their position. (...) ‘Back’ and ‘front’ exist as well. Eternalists stress that ‘now’ is indexical in a similar way. It is equally real with ‘past’ and ‘future’. Events are classified as past, present, or future from some perspective. -/- Eternalism is contrasted with presentism, which maintains that only present things exist and with the growing block view (also known as possibilism or no-futurism), which holds that past and present things exist but not future ones. The moving spotlight view suggests that all times exist but that the present is the only actual time. This view can be termed eternalist, but it preserves a non-perspectival difference between past, present, and future by treating tense as absolute. Additionally, the moving spotlight view retains some characteristics of presentism by maintaining that the ‘now’ is unique and privileged. -/- Broadly speaking, presentism is a common-sensical view, and so aligns with our manifest image of time. This view is, however, at odds with the scientific image of time. The primary motivation for eternalism arises from orthodox interpretations of the theories of relativity. According to them, simultaneity is relative, not absolute. This implies that there is no universal ‘now’ stretched out across the entire universe. One observer’s present can be another’s past or future. Assuming the universe is four-dimensional spacetime, then all events exist unconditionally. -/- The classical argument for eternalism was devised in the 1960s by Rietdijk in 1966 and Putnam in 1967, with subsequent follow-ups by Maxwell in 1985, Penrose in 1989, and Peterson and Silberstein in 2010. This argument and its ramifications remain the subject of ongoing debate. They shall be further explored in this entry, including their relation to other issues in the metaphysics of time and the philosophy of physics. (shrink)

Martin Nowak (2011; 2013) proposes five mechanisms for biological cooperation: kin selection, direct reciprocity, indirect reciprocity, net reciprocity, and group selection, which should explain every altruistic behavior. To test this, this paper presents two cases of adoption and alloparental care from two bonobo mothers to orphans outside of the group (Tokuyama et al., 2021). These cases demonstrate that none of the mechanisms proposed by Nowak accomplishes to explain altruistic behavior altogether. Finally, this paper challenges the assumptions that underlie Nowak’s theory (...) to conclude that the explicative insuffici e ncy of these assumptions prevents us from giving an account of biological cooperation in cases of animal adoption.
