Los conceptos de evolución y cambio evolutivo son a la vez laxos y polisémicos: se aplican a fenómenos muy diferentes y no siempre se definen con precisión. La aplicación extendida del paradigma neo-darwinista clásico, además, suele imponer un esquema adaptacionista al análisis de los hechos evolutivos, en el cual las funciones juegan un papel lógicamente anterior a los rasgos y sus formas. En este artículo proponemos, como etapa previa a la formulación de hipótesis sobre las causas del cambio, un modelo (...) de espacio forma-función que pueda responder a preguntas como cuándo se da un cambio en los rasgos de una arquitectura biológica y de qué tipo son estos cambios. Un modelo de este tipo nos permite ver claramente cuándo se da un cambio en la forma o en la función y qué alcance evolutivo tiene. (shrink)

The assumption that natural selection alone is sufficient to explain not only which traits get fixed in a population/species, but also how they develop, has been questioned since Darwin’s times, and increasingly in the last decades. Alternative theories, linked to genetic and phenotypic processes, or to the theory of complex systems, have been proposed to explain the rise of the phenotypic variety upon which natural selection acts. In this article, we illustrate the current state of the issue and we propose (...) a logical space based on phenotypic robustness that allows a classification of evolutionary phenomena and can provide a framework for unifying all these accounts.

El libro ademas de una historia personal es, un estudio sobre la politica de este siglo, escrito por uno de sus mas agudos observado-res.

While lecturing on the philosophy of history at the University of Berlin, Hegel was asked by a student if the United States ought to be considered the country of the future. Obviously irritated, he answered: “As the country of the future, America does not concern me … Philosophy deals with the eternal, or with reason, and with that there is enough to do.” In his famous lecture on science as a vocation, addressed to students at the University of Munich at (...) the end of the First World War, Max Weber responded to insistent questions on his views as to the future of Germany: “The classroom is neither for demagogues nor for prophets.”.

The great advances of the last decades both in cognitive theories and in evolutionary biology have not yet fully merged. Most evolutionary hypotheses around the mind still rely on classical cognitivism, while most theories of cognition still look for adaptive explanations. We believe that the merging of novel cognitive theories into a pluralistic account can greatly improve our understanding of both what cognition is and how it evolved.

Discussions about the extended mind have ‘extended’ in various directions in the last decades. While applied to other aspects of human cognition and even consciousness, the extended-mind hypothesis has also been criticized, as it questions fundamental ideas such as the image of a dual world, divided between an external and an internal domain by the border of ‘skin and skull’, the idea of a localized and constant decision center, and the role of internal representations. We suggest that the main virtue (...) of the hypothesis is not as a theory per se, but as a vaccine against persistent metaphysical prejudices about the mind’s structure, functions and borders. Being an hypothesis about the most efficient ways to combine resources and problems, and not a theory about the mind’s a-priori constitution, the extended mind view moves the focus from ontology to pragmatics and helps purify philosophy of mind from metaphysical remainders.

Darwin’s claim that Natural Selection, through optimization of fitness, explains complex biological design has not yet been properly formalized. Alan Grafen’s Formal Darwinism Project aims at providing such a formalization and at demonstrating that fitness maximization is coherent with results from Population Genetics, usually interpreted as denying it. We suggest that Grafen’s proposal suffers from some limitations linked to its concept of design as optimized fitness. In order to overcome these limitations, we propose a classification of evolutionary facts based on (...) a bi-dimensional complexity space, which adds robustness to fitness as measure of the quality of a design. In this space, each point represents an organismic architecture, and movement between two points would be an evolutionary fact. Natural Selection explains movement along the fitness axis, while non-selective mechanisms explain movement on the robustness axis. Moreover, we propose a thermodynamic metaphor to draw parallelisms between notions of fitness and entropy, robustness and energy, and movement in this space and reversible and irreversible cycles. We argue that this metaphor illustrates different evolutionary processes usually overlooked by proposals of formalization of Darwinian theory, such Grafen’s Formal Darwinism Project. (shrink)

A Political Life is the compelling autobiography of Norberto Bobbio, one of the foremost political thinkers in postwar Italy. In dramatic and lively prose, Bobbio guides us through some of the most significant events of the twentieth century, charting their influence on his life and work. Born in 1909, Norberto Bobbio's early life was marked by the experience of growing up in Mussolini's Italy - an experience that helped to shape his passionate commitment to the anti-fascist cause. As (...) a result of these early experiences, Bobbio has tirelessly emphasized the fundamental, unassailable importance of democratic rights in the modern state. He has been a voice of reason and moderation in a political context where democratic values have often been threatened by extremes. This masterly autobiography traces the development of Bobbio's political thought, providing a penetrating analysis of the changing political landscape of Italy. At the same time, it represents an intimate account of Bobbio's personal experiences, giving a rare insight into the life and work of this distinguished thinker.A Political Life will be of great interest to students and scholars of social and political theory and of Italian politics, as well as to a general readership interested in political biography and contemporary politics.

Frutto di una selezione estrema, i testi si dispongono secondo uno schema binario, per coppie dilemmatiche o contigue, secondo un caratteristico modo di procedere del suo pensiero. La scelta dei testi e la ricca curatela sono firmate da (...) Marco Revelli, noto storico, sociologo, professore "antiaccademico" e saggista. (shrink)

Purpose– The purpose of this paper is to introduce the term Slow Tech as a way of describing information and communication technology that is good, clean and fair. These are technologies that are human centred, environmentally sustainable and socially desirable.Design/methodology/approach– The paper's approach is based on a qualitative discourse that justifies the introduction of Slow Tech as a new design paradigm.Findings– The limits of the human body, and the need to take into account human wellbeing, the limits of the planet (...) and stakeholders' interests in decision making, all suggest the need for a new paradigm, Slow Tech, in the design of ICT and ICT systems. Three scenarios are described as case studies.Practical implications– In order to prepare the next generation of researchers and computer professionals, many different actions need to be taken. Universities and colleges need to redesign education programmes for computer scientists and engineers by introducing subjects related to the social and ethical implications of computing, and computer professionals' associations need to introduce a code of ethics or ethical analysis into their members' career development. As a result, future computer professionals who are familiar with the Slow Tech approach will be able to collaborate much more easily across the kind of cross disciplinary teams suited to design human centred, sustainable and desirable technologies.Social implications– Rather than simply focusing on the role of computer professionals, all members of society are called to play a new role in the design of future ICT scenarios. Starting a societal dialogue that involves computer professionals, users, researchers, designers, ICT industrialists, and policy makers is very much needed.Originality/value– The value of this paper is in its call for reflection followed by action. Based on an holistic approach to the design of new ICT systems, the paper advocates a new starting point for systems design: it should be based on a long-term view of the desirability and social importance of technologies, their environmental impact and sustainability, and the fairness and equity of the conditions of workers involved in the computing manufacturing processes.

In this important volume, the leading political theorist and philosopher Norberto Bobbio confronts some of the most enduring moral questions of our time. Written over the last two decades of the twentieth century, the essays in this volume develop some of the central themes in Bobbio's moral and political philosophy. They also reflect his longstanding civil commitment to liberty, democracy, peace and equality. The opening essay, 'In praise of meekness', analyses the virtue of meekness in its individual and social (...) aspects. It identifies the meek person with the nonviolent, and meekness with the refusal to exercise violence against anyone. Meekness, therefore, is a non-political virtue - it is the antithesis of politics. The volume also addresses the persistent classical problem of 'reason of state', as well as the more contemporary questions of tolerance and truth, racism, prejudice and ethics. The problem of evil in the modern world is also discussed. All the essays display the sensitivity and depth of understanding that characterize Bobbio's writings on current debates and historical controversies. The book will be invaluable reading for all students and scholars of politics, as well as those who are interested in the debates surrounding morals, ethics and law. (shrink)

In his autobiographical sketch, the author surveys sixty years of legal philosophy. He traces the major changes that have come about in the philosophy of law in the wake of the Second World War, and the gap which has been bridged between Continental and Anglo‐Saxon theories. The values of liberal democracy and the acknowledgement of human rights have helped to circumvent the gulf between natural law theories and legal positivist theories.

A theoretical framework for the reinforcement learning of aesthetic biases was recently proposed based on brain circuitries revealed by neuroimaging. A model grounded on that framework accounted for interesting features of human aesthetic biases. These features included individuality, cultural predispositions, stochastic dynamics of learning and aesthetic biases, and the peak-shift effect. However, despite the success in explaining these features, a potential weakness was the linearity of the value function used to predict reward. This linearity meant that the learning process employed (...) a value function that assumed a linear relationship between reward and sensory stimuli. Linearity is common in reinforcement learning in neuroscience. However, linearity can be problematic because neural mechanisms and the dependence of reward on sensory stimuli were typically nonlinear. Here, we analyze the learning performance with models including optimal nonlinear value functions. We also compare updating the free parameters of the value functions with the delta rule, which neuroscience models use frequently, vs. updating with a new Phi rule that considers the structure of the nonlinearities. Our computer simulations showed that optimal nonlinear value functions resulted in improvements of learning errors when the reward models were nonlinear. Similarly, the new Phi rule led to improvements in these errors. These improvements were accompanied by the straightening of the trajectories of the vector of free parameters in its phase space. This straightening meant that the process became more efficient in learning the prediction of reward. Surprisingly, however, this improved efficiency had a complex relationship with the rate of learning. Finally, the stochasticity arising from the probabilistic sampling of sensory stimuli, rewards, and motivations helped the learning process narrow the range of free parameters to nearly optimal outcomes. Therefore, we suggest that value functions and update rules optimized for social and ecological constraints are ideal for learning aesthetic biases. (shrink)

Based on the notion of bad faith, the article seeks to lay the foundations for a diagnosis of contemporaneity, having as an index, on the one hand, the lack of human determination and, on the other, the effectiveness of the world.

The problem of the relationship between “reason” and “law” has two different meanings depending on whether the first or the second of the two terms is considered to be the most important one. These two different meanings are revealed in the expressions “law of reason” and “legal reason,” respectively. In the first expression, “reason” is meant in its strong sense, that is, the faculty of grasping the essence of things, while in the second, “reason” is meant in a weak sense, (...) the ability to reason (calculate, infer, discuss). “Law of reason” and “legal reason” correspond to two different moments of the legal universe, the creation and, respectively, the application of law. Strong reason is that which discovers the rules to be obeyed, while weak reason is that which applies rules to an actual case. The first is legislating reason, while the second is judging reason. The main topic of the debate from the Greeks to Kant was that of legislating reason. Nowadays, instead, scholars in the field are interested in judging reason. Historicism and positivism mark the end of faith in the existence of rules which are objectively just, and which may be recognized by human reason. By now we have learned to do without the eternal truths in the knowledge of the world. However painful it may be, we are forced to resign ourselves to do without evident truths in ethics, as well.

The COVID-19 pandemic poses extraordinary public health challenges. In order to respond to such challenges, most democracies have relied on so-called ‘evidence-based’ policies, which supposedly devolve to science the burden of their justification. However, the biomedical sciences can only provide a theory-laden evidential basis, while reliable statistical data for policy support is often scarce. Therefore, scientific evidence alone cannot legitimise COVID-19 public health policies, which are ultimately based on political decisions. Given this inevitable input on policy-making, the risk of arbitrariness (...) is ubiquitous and democratic scrutiny becomes essential to counter it. During the COVID-19 pandemic, the standards of scientific and democratic scrutiny have been, as a matter of fact, substantially lowered. This erosion potentially damages democracy. (shrink)

El proyecto del ‘Darwinismo Formal’ de Alan Grafen propone una formulación matemática de la teoría de Darwin que pretende demostrar que la selección natural moldea los rasgos fenotípicos a través de la maximización de la eficacia. El proyecto de Grafen reposa sobre tres premisas: la selección natural es la única fuerza que moldea los fenotipos; la eficacia es la única medida de le evolución; y el diseño biológico surge como resultado de un proceso de optimización selectiva. En este trabajo argumentamos (...) que estas tres premisas limitan la aplicabilidad del modelo a los hechos evolutivos más simples. Esto se debe a que Grafen implícitamente presupone un concepto de eficacia que es a la vez causa y efecto de las novedades fenotípicas; lo que, por un lado, vacía la teoría de Darwin de poder explicativo y, por el otro, lleva a ignorar la potencial contribución de fuerzas evolutivas no selectivas en la configuración de la complejidad biológica. Para superar estos escollos del proyecto de del Darwinismo Formal - que son además comunes a todos los modelos formales adaptacionistas - proponemos sustituir el concepto causal de eficacia por el de robustez, definiendo así el diseño biológico como forma y función en lugar de como maximización de la eficacia.

This article discusses the contribution to evolutionary theory of Leonard Darwin, the eighth child of Charles Darwin. By analysing the correspondence Leonard Darwin maintained with Ronald Aylmer Fisher in conjunction with an assessment of his books and other written works between the 1910s and 1930s, this article argues for a more prominent role played by him than the previously recognised in the literature as an informal mentor of Fisher. The paper discusses Leonard’s efforts to amalgamate Mendelism with both Eugenics and (...) Darwinism in order for the first to base their policies on new scientific developments and to help the second in finding a target for natural selection. Without a formal qualification in biological sciences and as such mistrusted by some “formal” scientists, Leonard Darwin engaged with key themes of Darwinism such as mimicry, the role of mutations on speciation and the process of genetic variability, arriving at important conclusions concerning the usefulness of Mendelian genetics for his father’s theory.

The text is part of the investigative concerns from the authors with regard to the dialogue between literature and science teaching. It starts from several theoretical approaches around the general didactics, university or superior didactics, science’s didactics and for last, literature’s didactics. This is largely due to our search which is focused in articulate the university didactics with science and literature’s didactics, meanwhile, we pretend to answer to the questions ¿How are the specific didactics of science and literature going to (...) contribute to the university didactics and how is the last one going to contribute to these specific didactics? ¿Is it the dialogue between science and literature possible? The paper has been made in middle education, in Educative Institution José Miguel de Restrepo y Puerta, from Copacabana and also in university education, in the academic unities of Dietetics and Nutrition School, Agricultural Sciences and Medicine, from the University of Antioquia. Finally, the partial results indicate: i) the necessity of general Didactics as a discipline focused on teaching and learning processes to ask itself for its internal problems and establish relations with specific didactics.

Mexico faces a crisis of national sovereignty and independence as it struggles to establish a democracy amidst integration into the world market system and internal demands for social justice. U.S. involvement in Mexican affairs, providing military training and equipment for government troops, contributes to a state-sponsored war against civilians, namely indigenous groups and the middle and lower classes devastated by NAFTA. While resistance movements in Chiapas respond to capitalist practices and repression, Valdez argues the Mexican government minimizes them to displace (...) its indigenousgroups and facilitate their silent annihilation. U.S. policy, the Mexican state, indigenous issues, and free trade are interconnected with Mexico’s larger society. (shrink)

Purpose– The purpose of this paper is to examine how Slow Tech can support the celebration of the 20-year series of ETHICOMP conferences, with its ethical and societal focus, building on earlier descriptions of Slow Tech. The paper takes Slow Tech’s ideas a step further to explore how a roadmap and concrete checklist of activities can be developed.Design/methodology/approach– The paper is a thought leadership or conceptual piece. Its approach is based on a normative, qualitative discourse. It, nevertheless, indicates a shift (...) towards concrete actions.Findings– Extracting from a brief historical overview, the paper lays out the means of building a Slow Tech roadmap and a Slow Tech checklist of actions. It also investigates a number of the challenges that might face Slow Tech in the future.Research limitations/implications– The paper has implications for stakeholder fields as far-ranging as corporations, computing professional associations, universities and research institutions and end-users.Originality/value– As with other investigations of Slow Tech, the value of this paper is in its call for reflection followed by action. It provides a useful complement and counterbalance to an earlier paper by the same authors: “Slow Tech: a quest for good, clean and fair ICT” published inJournal of Information, Communication and Ethics in Society.

Purpose– This paper aims to provide an overview of clean information and communication technology, including a brief review of recent developments in the field and a lengthy set of possible reading matter. The need to rethink the impact of ICTs on people’s lives and the survival of the planet is beginning to be addressed by a Slow Tech approach. Among Slow Tech’s main questions are these two: Is ICT sustainable in the long term? What should be done by computer ethics (...) scholars, computer professionals, policy makers and society in general to ensure that clean ICT can be produced, used and appropriately disposed of?Design/methodology/approach– The paper is based on a comprehensive review of clean tech-related literature and an investigation of progress made in the clean tech field.Findings– This opening paper of aJournal of Information, Communication and Ethics in Societyspecial session aims to provide an overview of clean ICT, including a brief review of recent developments in the field and a lengthy set of possible reading matter. As a result, it is anticipated that Slow Tech – and in this case, its second component of clean ICT – can provide a compass to steer research, development and the use and reuse of environmentally friendly, sustainable ICT.Originality/value– This conceptual paper emphasises that, until only recently, no one questioned the potential long-term sustainability of ICT. This issue is, however, now very much a matter that is on the research and teaching, and action, agenda. (shrink)
