In actuarial parlance, the price of an insurance policy is considered fair if customers bearing the same risk are charged the same price. The estimate of this fair amount hinges on the expected value obtained by weighting the different claims by their probability. We argue that, historically, this concept of actuarial fairness originates in an Aristotelian principle of justice in exchange (equality in risk). We will examine how this principle was formalized in the 16th century and shaped in life insurance (...) during the following two hundred years, in two different interpretations. The Domatian account of actuarial fairness relied on subjective uncertainty: An agreement on risk was fair if both parties were equally ignorant about the chances of an uncertain event. The objectivist version grounded any agreement on an objective risk estimate drawn from a mortality table. We will show how the objectivist approach collapsed in the market for life annuities during the 18th century, leaving open the question of why we still speak of actuarial fairness as if it were an objective expected value.

We defend, from a contractarian perspective, that the fair price of an insurance policy is the amount that the contracting parties agree when they are both equally uncertain about the insured event. Drawing on the approach developed by R. Sugden in _The Community of Advantage_, we answer two standard objections raised against contractarianism in the actuarial sciences: (1) people are not wise enough to assess their actuarial risks; (2) they are not rational enough to decide which insurance policy suits them (...) better. We show under which circumstances people can make fair actuarial agreements, without presupposing any objective risk or rationality benchmarks. (shrink)

Exploramos aquí la conexión entre los conceptos de riesgo e igualdad en el argumento del observador imparcial. La concepción de la justicia que elegiría un observador imparcial se justifica por la pureza del procedimiento de elección. Sin embargo, si modelizamos esta decisión utilizando medidas del riesgo habituales en matemática financiera, veremos cómo el criterio de elección del observador bajo el velo de la ignorancia contiene una preferencia implícita por el grado de desigualdad resultante. Esto nos obliga a reconsiderar la pureza (...) procedimental de la elección. (shrink)

Tradicionalmente, las primas de los contratos de seguros se han considerado justas o equitativas cuando se corresponden exactamente con el riesgo de las pólizas, medido este último mediante la esperanza matemática de la siniestralidad. En este artículo llevamos a cabo una crítica de este enfoque aparentemente objetivo y proponemos una justificación alternativa de la denominada equidad actuarial, basada en argumentos contractualistas. Para ello nos apoyamos en ciertas intuiciones de Jean Domat, un jurista francés del siglo XVII, acerca de la incertidumbre (...) compartida, integradas dentro del marco general proporcionado por la teoría contractualista del economista y filósofo contemporáneo Robert Sugden.

Behavioral interventions have shown promising neuroprotective effects, but the cascade of molecular, brain and behavioral changes involved in these benefits remains poorly understood. Projecte Moviment is a 12-week multi-domain, single-blind, proof-of-concept randomized controlled trial examining the cognitive effect and underlying mechanisms of an aerobic exercise, computerized cognitive training and a combined groups compared to a waitlist control group. Adherence was > 80% for 82/109 participants recruited. In this study we report intervention-related changes in plasma biomarkers and structural-MRI and how they (...) related to changes in physical activity and individual variables and their potential role as mediators in the cognitive changes. Our results show that although there were no significant changes in molecular biomarker concentrations in any intervention group, changes in ICAM-1 and SDF1-α were negatively associated with changes in physical activity outcomes in AE and COMB groups. Brain volume changes were found in the CCT showing a significant increase in precuneus volume. Sex moderated the brain volume change in the AE and COMB groups, suggesting that men may benefit more than women. Changes in molecular biomarkers and brain volumes did not significantly mediate the cognitive-related benefits found previously for any group. This study shows crucial initial molecular and brain volume changes related to lifestyle interventions at early stages and highlights the value of examining activity parameters, individual difference characteristics and using a multi-level analysis approach to address these questions.

Sometimes I feel that Sorgner's ideas can foresee the questions I can ask about his philosophy. But I cannot claim that he is a prophet of Apollo. Instead, his latest work continues to embrace a Dionysian constant, showing the reaches of an ontology of per-manent becoming and putting into practice his own understanding of philosophy, namely an "Intellectual War of Values". Such a statement is Hera-clitean and, therefore, also Nietzschean. In this sense, Philosophy of Posthuman Art is not a work (...) independent of the author's other works, but a necessary consequence of his global intellectual production. (shrink)

This book is the first monograph fully devoted to analyzing the philosophical aspects of affordances. The concept of affordance, coined and developed in the field of ecological psychology, describes the possibilities for action available in the environment. This work offers a systematic approach to the key philosophical features of affordances, such as their ontological characterization, their relation to normative practices, and the idea of agency that follows from viewing affordances as key objects of perception, while also proposing an innovative philosophical (...) characterization of affordances as dispositional properties. The Philosophy of Affordances analyzes the implications that a proper understanding of affordances has for the philosophy of mind and the cognitive sciences, and aims to intensify the dialogue between philosophy and ecological psychology in which each discipline benefits from the tools and insights of the other.

INCONTINENCE, HONOURING SUNK COSTS AND RATIONALITY According to a basic principle of rationality, the decision to engage in a course of action should be determined solely by the analysis of its consequences. Thus, considerations associated with previous use of resources should have no bearing on an agent’s decision-making process. Frequently, however, agents persist carrying on an activity they themselves judge to be nonoptimal under the circumstances because they have already allocated resources to that activity. When this is the case, agents (...) are said to be honouring sunk costs. Honouring sunk costs is thus typically viewed as irrational economic behaviour. Two striking findings of the psychological literature on the sunk cost effect are that it is, in general, not lessened by having taken previously courses in economics, and that agents who did take such courses and that do honour sunk costs seem to be frequently aware of a cognitive dissonance in their behaviour. Davidson’s account of the possibility conditions of incontinent action renders continent action materially unfeasible. The very idea of incontinent action becomes thus a hollow one. I’ll present an alternative description of these possibility conditions that renders continent action materially feasible, and both, continent and incontinent action, cognitively plausible. In a nutshell, my proposal rests upon the drawing of an essential cognitive contrast between explicit processes of deliberative reasoning and lower level heuristic procedures. I conclude the paper arguing that my redescription of incontinent action accounts for the above mentioned cognitive dissonance effect better than the alternatives and that viewing at least an important subset of behaviours of honouring sunk costs as incontinent actions will enable us to consider them as peculiar manifestations of a more general and meaningful pattern in human behaviour.

Ecological psychology is one of the most influential theories of perception in the embodied, anti-representational, and situated cognitive sciences. However, radical enactivists claim that Gibsonians tend to describe ecological information and its ‘pick up’ in ways that make ecological psychology close to representational theories of perception and cognition. Motivated by worries about the tenability of classical views of informational content and its processing, these authors claim that ecological psychology needs to be “RECtified” so as to explicitly resist representational readings. In (...) this paper, we argue against this call for RECtification. To do so, we offer a detailed analysis of the notion of perceptual information and other related notions such as specificity and meaning, as they are presented in the specialized ecological literature. We defend that these notions, if properly understood, remain free of any representational commitment. Ecological psychology, we conclude, does not need to be RECtified. (shrink)

This paper argues that it is possible to combine enactivism and ecological psychology in a single post-cognitivist research framework if we highlight the common pragmatist assumptions of both approaches. These pragmatist assumptions or starting points are shared by ecological psychology and the enactive approach independently of being historically related to pragmatism, and they are based on the idea of organic coordination, which states that the evolution and development of the cognitive abilities of an organism are explained by appealing to the (...) history of interactions of that organism with its environment. It is argued that the idea of behavioral or organic coordination within the enactive approach gives rise to the sensorimotor abilities of the organism, while the ecological approach emphasizes the coordination at a higher-level between organism and environment through the agent’s exploratory behavior for perceiving affordances. As such, these two different processes of organic coordination can be integrated in a post-cognitivist research framework, which will be based on two levels of analysis: the subpersonal one and the personal one. If this proposal is on the right track, this may be a promising first step for offering a systematized and consistent post-cognitivist approach to cognition that retain the full potential of both enactivism and ecological psychology.

We examine the comportment of the global trajectory of a piecewisely conceived single species population growth model. Formulation relies on what we develop as the principle of limiting factors for population growth, adapted from the law of the minimum of Liebig and the law of the tolerance of Shelford. The ensuing paradigm sets natality and mortality rates to express through extreme values of population growth determining factor. Dynamics through time occur over different growth phases. Transition points are interpreted as thresholds (...) of viability, starvation, and intraspecific competition. In this delivery, we focus on the qualitative study of the global trajectory expressed on continuous time and on exploring the feasibility of analytical results against data on populations growing under experimental or natural conditions. All study cases sustained fittings of high reproducibility both at empirical and interpretative slants. Possible phase configurations include regimes with multiple stable equilibria, sigmoidal growth, extinction, or stationarity. Here, we also outline that the associating discrete-time piecewise model composes the logistic map applied over a particular region of the phase configuration. Preliminary exploratory analysis suggests that the logistic map’s chaos onset could surpass once the orbit enters a contiguous phase region. (shrink)

In this article we introduce the concept of implied optical perspective in deep learning computer vision systems. Taking the BBC's experimental television programme “Made by Machine: When AI met the Archive” as a case study, we trace a conceptual and material link between the system used to automatically “watch” the television archive and a specific type of photographic practice. From a computational aesthetics perspective, we show how deep learning machine vision relies on photography, its technical regimes and epistemic advantages, and (...) we propose a novel way to identify the latent camera through which the BBC archive was seen by machine.

In this paper we explore in what sense we can claim that affordances, the objects of perception for ecological psychology, are related to normativity. First, we offer an account of normativity and provide some examples of how it is understood in the specialized literature. Affordances, we claim, lack correctness criteria and, hence, the possibility of error is not among their necessary conditions. For this reason we will oppose Chemero’s normative theory of affordances. Finally, we will show that there is a (...) way in which taking advantage of affordances could be considered as possessing a normative character, but only when they are evaluated within the framework of social normative standards in particular situations. This reinforces our claim that affordances, per se, lack normativity and can only be taken to be rule-governed in relation to established normative practices. (shrink)

This paper aims to examine the evolutionary role of affordances, that is, the possibilities for action available in our environments. There are two allegedly competing views for explaining the evolutionary role of affordances: the first is based on natural selection; the second is based on niche construction. According to the first, affordances are resources that exert selection pressure. The second view claims that affordances are ecological inheritances in the organism’s niche that are the product of a previous alteration of the (...) environment. While there seems to be a mutually exclusive definition of affordances in each of these views, I argue in this paper that the views are not competing but, rather, complementary. In this sense, affordances play the role of either resources or ecological inheritances depending on the temporal stage of the evolutionary process. I make this argument by analyzing how natural selection and niche construction affect each other even when they function independently from each other. In this light, if these two evolutionary mechanisms exert their power in parallel but at two different stages in the evolutionary history of a given econiche, then there is room to claim that affordances can be understood as both resources and ecological inheritances. This dual aspect of affordances shows their evolutionary role. (shrink)

Antonio Negri wrote the two essays that comprise Time for Revolution while serving a prison sentence for alleged involvement with radical left-wing groups. Although the essays were written two decades apart, their concerns are the same: is there a place for resistance in a society utterly subsumed by capitalism? In the wake of the global crisis of capitalism heralded by the 2008 crash, the question has never been more relevant and Negri remains an insightful and passionate guide to any (...) attempt to answer it.

This paper argues that the normative character of our unreflective situated behaviour is not factual. We highlight a problematic assumption shared by the two most influential trends in contemporary philosophy of cognitive science, reductionism and enactivism. Our intentional, normative explanations are referential, descriptive or factual. Underneath this assumption lies the idea that only facts can make true or false our attributions of cognitive, mental and agential abilities. We will argue against this view by describing the main features and problems of (...) reductionism and enactivism and then we will offer two arguments against this shared factualist assumption: (1) normative vocabulary is ineliminable if we want a complete explanation of our situated practices; and (2) the factualist assumption is a species of the is-ought fallacy. Finally, we will claim that a folk psychological explanation of our normative practices is fully compatible with ontological naturalism when such descriptivist or factualist assumption is rejected.

A widely shared assumption in the literature about skilled motor behavior is that any action that is not blindly automatic and mechanical must be the product of computational processes upon mental representations. To counter this assumption, in this paper we offer a radical embodied (non-representational) account of skilled action that combines ecological psychology and the Deweyan theory of habits. According to our proposal, skilful performance can be understood as composed of sequences of mutually coherent, task-specific perceptual-motor habits. Such habits play (...) a crucial role in simplifying both our exploration of the perceptual environment and our decision-making. However, we argue that what keeps habits situated, precluding them from becoming rote and automatic, are not mental representations but the agent's conscious attention to the affordances of the environment. It is because the agent is not acting on autopilot but constantly searching for new information for affordances that she can control her behavior, adapting previously learned habits to the current circumstances. We defend that our account provides the resources needed to understand how skilled action can be intelligent (flexible, adaptive, context-sensitive) without having any representational cognitive processes built into them.

This paper argues that the Extended Synthesis, ecological information, and biosemiotics are complementary approaches whose engagement will help us explain the organism-environment interaction at the cognitive level. The Extended Synthesis, through niche construction theory, can explain the organism-environment interaction at an evolutionary level because niche construction is a process guided by information. We believe that the best account that defines information at this level is the one offered by biosemiotics and, within all kinds of biosemiotic information available, we believe that (...) ecological information is the best candidate for making sense of the organism-environment relation at the cognitive level. This entanglement of biosemiotics, ecological information and the Extended Synthesis is promising for understanding the multidimensional character of the organism-environment reciprocity as well as the relation between evolution, cognition, and meaning.

In this paper, we offer a criticism, inspired by Wittgenstein’s rule-following considerations, of the enactivist account of perception and action. We start by setting up a non-descriptivist naturalism regarding the mind and continue by defining enactivism and exploring its more attractive theoretical features. We then proceed to analyse its proposal to understand normativity non-socially. We argue that such a thesis is ultimately committed to the problematic idea that normative practices can be understood as private and factual. Finally, we offer a (...) characterization of normativity as an essentially social phenomenon and apply our criticisms to other approaches that share commitments with enactivism. (shrink)

Open peer commentary on the article “Perception-Action Mutuality Obviates Mental Construction” by Martin Flament Fultot, Lin Nie & Claudia Carello. Upshot: This commentary highlights some controversial aspects of enactivism and ecological psychology, specifically the notions of subjectivity and ecological information. I argue that, instead of choosing between them, both theories could complement each other at different levels of analysis in a single research framework for explaining cognition from a situated perspective.

This article presents, an analysis of the opinions of assurance providers regarding the quality and the limitations of sustainability reports and their recommendations to improve them using the Global Reporting Initiative as a framework. The qualitative content analysis of 301 assurance statements for sustainability reports from mining and energy companies provides a comprehensive view of the main outcomes of the assurance process, including its limitations, the application of the GRI principles and suggestions for improving sustainability reports. Taking into account the (...) perceptions of practitioners a priori well informed on the quality of sustainability reports—namely assurance providers—this paper complements the current literature on sustainability reporting and its assurance, including critical approaches that question the reliability of sustainability reports, stakeholder engagement and the accountability of reporting practices. This study contributes to the debates surrounding the quality of sustainability reports, the added value of assurance statements and the ethical issues underlying the assurance process. It also contains important practical implications for auditors, standardization organizations and stakeholders. (shrink)

The increasing pressures to conserve biodiversity—particularly for industries based on the exploitation of natural resources—have reinforced the need to implement specific measures in this area. Corporate commitment to preserving biodiversity is increasingly scrutinized by stakeholders and now represents an important aspect of business ethics. Although stakeholder involvement is often essential to the management of biodiversity, very few studies in the literature have focused on the details of this involvement. The objective of this paper is to analyze how mining and forestry (...) companies can manage biodiversity issues through stakeholder involvement based on a content analysis of 430 sustainability reports using the Global Reporting Initiative framework. The paper elucidates the reasons for such involvement, the nature of stakeholders involved, and the types of measures employed to manage biodiversity. Stakeholders’ motives for becoming involved revolve around four main issues: complexity and knowledge management; self-regulation and relationships with public authorities; legitimacy and social responsiveness; and commercial and strategic objectives. The stakeholders involved in biodiversity initiatives are essentially non-governmental organizations, experts and universities, public authorities, and coalitions of companies. In the end, the initiatives identified can be grouped into three categories: management practices, socio-political actions, and research and conservation measures. The paper provides various examples of these initiatives and shows how they can be implemented in collaboration with different stakeholders depending on the company’s objectives. The contributions the study makes to the literature on biodiversity management and the managerial implications of the study are analyzed in the discussion section. (shrink)

In the last years, we have attended to different attempts to extend the notion of affordance to include mental or cognitive actions. In short, the idea is that our capacity to perform some cognitive functions such as counting, imagining, mathematical reasoning, and so on, is preceded by our awareness of cognitive or mental affordances. In this paper, we analyze two of these attempts, Mental Affordance Hypothesis, and cognitive horizons, and conclude that they fail to deliver their promise. Our argument is (...) two-fold. First, we show that both proposals lack an explanation for how these affordances can be perceived or experienced by the individuals. Second, we argue, focusing on the examples provided by the authors, that the introduction of cognitive affordances is not justified on explanatory grounds. In other words, neither of these proposals offers a compelling justification for thinking that performing said “mental acts” requires the perception of mental or cognitive affordances. Hence, the existence of mental or cognitive affordances remains both scientifically mysterious and explanatorily unjustified. (shrink)

This paper aims to defend that the best framework for characterizing dispositions is a Rylean, non-factualist dispositionalism. I follow Tugby, 451–480, 2013) in explaining which are the main candidates for characterizing the ontology of dispositions. Tugby, 451–480, 2013) concludes that the best metaphysical framework for characterizing dispositions is Platonism, because it is the only theory that can account for the central and the intrinsic platitudes. Following this I show that Platonism is not desirable because it is difficult to reconcile with (...) ontological naturalism and because it is not parsimonious. Thus, I offer a different candidate: Rylean non-factualist dispositionalism. This approach retains the explanatory power of our dispositional vocabulary without appealing to facts, entities, or properties. In conclusion, non-factualist dispositionalism is preferable over naturalism and Platonism for characterizing dispositions. (shrink)

This article aims to propose some connections between the conceptions of poetry of the Mexican poet Octavio Paz and the German philosopher Martin Heidegger. Both see in poetry the element of recognition of the original condition of the human being, not as an interpretation, but as a perception and affectation of the existential reality of human beings. So that the event of the "poetic saying" is configured as a call to the possibility of glimpsing the being of each entity, inhabiting (...) oneself and, thus, learning to be with others, establishing the poetic field as the clearing of perception and of existential affectation. Poetic speech goes beyond the limits of language, creating and establishing meanings and representations to the affectations that poetry provides. Thus, through poetry man recognizes himself in his worldliness, in search of his own being and in his relationship with other beings. (shrink)

The objective of this paper is to investigate, through a qualitative study based on 38 semi-structured interviews with agents who provide assurance of sustainability reports, how they perceive and manage ethical issues underlying the verification of sustainability reports. Most of the ethical issues observed involve four interconnected aspects: the commercialism underlying sustainability assurance, the symbolic nature of the verification process, interdependency between auditing and consulting activities, and familiarity with the audited companies. The findings shed light on the reflexivity of assurance (...) providers on these issues and the legitimation strategies used to explain how they reconcile the independence and impartiality required for auditing activities with commercial aspects related to client–provider relationships. The study also shows the role of contextual variables in the ethics of assurance services. The paper contributes to the literature on the legitimacy of sustainability assurance and commercialism of the audit function. Practical implications and avenues for future research are also developed. (shrink)

In this paper we challenge the notion of ‘normativity’ used by some enactive approaches to cognition. We define some varieties of enactivism and their assumptions and make explicit the reasoning behind the co-emergence of individuality and normativity. Then we argue that appealing to dispositions for explaining some living processes can be more illuminating than claiming that all such processes are normative. For this purpose, we will present some considerations, inspired by Wittgenstein, regarding norm-establishing and norm-following and show that attributions of (...) normativity to non-social agents are deeply paradoxical. The main conclusions of our discussion are: (1) circular and internal explanations centred on the stability of living systems are insufficient to account for processes where the environment plays an important role, such as adaptation. Enactivism is not an explanatory alternative to evolutionary biology but needs it as a complement to accounts focused on the internal self-assembly of organisms; (2) though we share enactivism’s anti-representational spirit, we argue that ecological psychology can offer a better account of perception.
