The cumulative impact of enhancement technologies may alter the human species in the very long-term future. In this article, I will start showing how radical genetic enhancements may accelerate the conversion into a novel species. I will also clarify the concepts of ‘biological species’, ‘transhuman’ and ‘posthuman’. Then, I will summarize some ethical arguments for creating a transhuman or posthuman species with a substantially higher level of well-being than the human one. In particular, I will present what I shall call (...) the Principle of the Best Interests of Posthumanity, which states that the enhancement of the human and transhuman species must be directed towards the creation of a posthuman existence that is substantially more valuable than its predecessors. I suggest that human extinction may be considered, within that principle, as one of the best interests of posthumanity. Finally, I will develop three objections that make that principle unattractive and that show that pursuing a full-blown programme of posthuman evolution is ethically flawed. (shrink)

The philosophical model of constellation has been applied to contemporary musical form, but it reveals too many limitations when confronted with late Adorno’s model of informal music. Once the component of heteronomy, in hierarchical and centered structures of traditional music, has been overcome, it reemerges in the opposite type, the decentered, non-hierarchical or free structures, between the opposites of serialism and aleatoric music. Therefore, the model of informal music, as an "image of freedom", pursues the realization of a musical-aesthetic nominalism (...) that is subtracted from all forms of heteronomy, ancient or modern. To do this, it has to achieve the 'actually constructed totality' of the work, integrating in it the opposite of free subjectivity. (shrink)

It has been suggested that due to AI-technology-generated gadgets, a digital unconscious enables the probable annulment of the Freudian unconscious. The purpose of this article is to delve into Freudian topography as a way to demonstrate that this foreclosure of the unconscious was somewhat present in Freud as of 1920. In addition, regardless of solid attempts at the extinction of the unconscious by contemporary demands, I will focus on how the capitalist discourse and AI-generated technology propose a different form of (...) social bond. Finally, the conceptualization of pain (_Schmerz_) is important for ascribing a different modality to the Freudian unconscious than in recent dissertations, but most importantly, it is a significant element for analytical experience to function properly where it must not be aligned with suffering. An era without an unconscious may foretell a time where enjoyment, as a form of subjectivity, is effaced. (shrink)

Esta tesis tiene como objetivo proponer una perspectiva crítica que permita un análisis filosófico del arte que fue desarrollada a partir de una lectura de El arte como experiencia de John Dewey. Para ello, recupero en primer lugar dos conceptos centrales, arte y experiencia, para desarrollar luego tres conceptos subsidiarios, expresión, comunicación y educación de la sensibilidad.

Forms of Life and Subjectivity: Rethinking Sartre's Philosophy explores the fundamental question of why we act as we do. Informed by an ontological and phenomenological approach, and building mainly, but not exclusively, on the thought of Sartre, Daniel Rueda Garrido considers the concept of a ""form of life"" as a term that bridges the gap between subjective identity and communities.

The application of Artificial Intelligence (AI) in healthcare and epidemiology undoubtedly has many benefits for the population. However, due to its environmental impact, the use of AI can produce social inequalities and long-term environmental damages that may not be thoroughly contemplated. In this paper, we propose to consider the impacts of AI applications in medical care from the One Health paradigm and long-term global health. From health and environmental justice, rather than settling for a short and fleeting green honeymoon between (...) health and sustainability caused by AI, it should aim for a lasting marriage. To this end, we conclude by proposing that, in the upcoming years, it could be valuable and necessary to promote more interconnected health, call for environmental cost transparency, and increase green responsibility.

Tanto el transhumanismo como el posthumanismo filosófico han prestado una atención especial a la corporalidad humana en relación al avance tecnológico. En el presente artículo, se comienza señalando cómo ambos movimientos difieren significativamente respecto a la herencia del humanismo. Posteriormente, se aborda la noción transhumanista de la ‘libertad morfológica’ de la mano de More, Sandberg y Bostrom. A continuación, se presentan casos paradigmáticos de modificaciones corporales mediante implantes cibernéticos. En último lugar, se problematizan las cuestiones de la identidad, la corporalidad (...) y el desencuentro entre ambas corrientes respecto al ‘volcado de la mente’. -/- Transhumanism and philosophical posthumanism have paid special attention to human corporeality in relation to technological breakthroughs.

Then, paradigmatic cases of body modifications through cybernetic implants are considered. Finally, the issues of identity, corporeality, and the disagreement between the two currents regarding ‘mind uploading’ are problematized. (shrink)

Desde hace varias décadas, la opinión pública se ha ido trasladando, en gran parte, desde los salones domésticos y los cafés a la red. El desarrollo de las tecnologías 2.0 ha dado lugar a una metamorfosis de la noción de "público" y ha hecho posible que, en el ciberespacio, el debate colectivo sea más abierto, participativo y distribuido respecto al que se produce en los medios tradicionales. Esta nueva esfera pública virtual, en la que surge y vive la opinión de (...) las masas, ha transformado y enriquecido las maneras de relacionarse y movilizarse políticamente, pero también entraña peligros como la manipulación de la información y la extrema polarización de las ideas que se comparten en los entornos digitales.Desde la doble perspectiva del análisis del discurso y de la pragmática lingüística, este libro aborda, de manera divulgativa, el estudio de las distintas manifestaciones de la opinión pública en los nuevos entornos digitales. Se analizan textos de naturaleza muy diversa, con el fin de mostrar las estrategias discursivas y los recursos lingüísticos más utilizados por los ciudadanos para expresar sus puntos de vista y reivindicar sus propuestas en la red.

El ensayo constituye una interpretación de la herencia de M. Heidegger en las filosofías de M. Foucault y G. Deleuze. Tal interpretación se hace desde una perspectiva precisa y selectiva. Se trata de analizar el modo en que la diferencia óntico-ontológica heideggeriana es transformada en el núcleo del pensamiento de estos dos pensadores. El autor parte de la tesis según la cual Heidegger conserva restos del pensamiento identitario en su concepción del ser, al caracterizarlo simultáneamente como acontecimiento diferencial y como (...) lo Mismo. Es esta dificultad la que intenta ser resuelta, de un modo semejante, en las filosofías de Foucault y de Deleuze. El ensayo sostiene que en estas últimas la mismidad es disuelta en favor de una «multiplicidad acontecimental en estado naciente». (shrink)

We present an approach to understanding the origin of inertia involving the electromagnetic component of the quantum vacuum and propose this as a step toward an alternative to Mach's principle. Preliminary analysis of the momentum flux of the classical electromagnetic zero-point radiation impinging on accelerated objects as viewed by an inertial observer suggests that the resistance to acceleration attributed to inertia may be at least in part a force of opposition originating in the vacuum. This analysis avoids the ad hoc (...) modeling of particle-field interaction dynamics used previously by Haisch, Rueda, and Puthoff (Phys. Rev. A 49, 678, (1994)) to derive a similar result. This present approach is not dependent upon what happens at the particle point, but on how an external observer assesses the kinematical characteristics of the zero-point radiation impinging on the accelerated object. A relativistic form of the equation of motion results from the present analysis. Its manifestly covariant form yields a simple result that may be interpreted as a contribution to inertial mass. We note that our approach is related by the principle of equivalence to Sakharov's conjecture (Sov. Phys. Dokl. 12, 1040, (1968)) of a connection between Einstein action and the vacuum. The argument presented may thus be construed as a descendant of Sakharov's conjecture by which we attempt to attribute a mass-giving property to the electromagnetic component—and possibly other components—of the vacuum. In this view the physical momentum of an object is related to the radiative momentum flux of the vacuum instantaneously contained in the characteristic proper volume of the object. The interaction process between the accelerated object and the vacuum (akin to absorption or scattering of electromagnetic radiation) appears to generate a physical resistance (reaction force) to acceleration suggestive of what has been historically known as inertia.

Scientific misconduct obstructs the advance of knowledge in science. Its impact in some disciplines is still poorly known, as is the frequency in which it is detected. Here, I examine how frequently editors of ecology and evolution journals detect scientist misconduct. On average, editors managed 0.114 allegations of misconduct per year. Editors considered 6 of 14 allegations (42.9%) to be true, but only in 2 cases were the authors declared guilty, the remaining being dropped for lack of proof. The annual (...) rate of allegations that were probably warranted was 0.053, although the rate of demonstrated misconduct was 0.018, while the rate of false or erroneous allegations was 0.024. Considering that several cases of misconduct are probably not reported, these findings suggest that editors detect less than one-third of all fraudulent papers. (shrink)

Ageism has unfortunately become a salient phenomenon during the COVID-19 pandemic. In particular, triage decisions based on age have been hotly discussed. In this article, I first defend that, although there are ethical reasons (founded on the principles of benefit and fairness) to consider the age of patients in triage dilemmas, using age as a categorical exclusion is an unjustifiable ageist practice. Then, I argue that ageism during the pandemic has been fueled by media narratives and unfair assumptions which have (...) led to an ethically problematic group homogenization of the older population. Finally, I conclude that an intersectional perspective can shed light on further controversies on ageism and triage in the post-pandemic future. (shrink)

Emerging reprogenetic technologies may radically change how humans reproduce in the not-so-distant future. One foreseeable consequence of disruptive innovations in the procreative domain is an increase in the reproductive autonomy of intended parents. Regarding the prospective parental liberty of enhancing non-health–related traits of the offspring, one controversy has particularly dominated the literature. Does parents' choice of genetically enhancing the traits of their descendants compromise children's future personal autonomy? In this article, I will analyse the main arguments which posit that reprogenetic (...) enhancement could be at odds with the child's future autonomy. I will argue that these objections are ill-founded. Moreover, I will present other arguments that show that reprogenetic technologies can enhance the autonomy of future children. Autonomy enhancement is a plausible and pro tanto desirable application of emerging reprogenetic technologies. (shrink)

Biomedical innovations are making possible the enhancement of human capabilities. There are two philosophical stances on the role that medicine should play in this respect. On the one hand, naturalism rejects every medical intervention that goes beyond preventing and treating disease. On the other hand, welfarism advocates enhancements that foster subjective well-being. We will show that both positions have considerable shortcomings. Consequently, we will introduce a third characterization in which therapies and enhancements can be reconciled with the legitimate objectives of (...) medicine inasmuch as they improve the capabilities that enable the freedom to pursue personal well-being.

Erick J. Ramirez, Miles Elliott and Per‑Erik Milam (2021) have recently claimed that using Virtual Reality (VR) as an educational nudge to promote empathy is unethical. These authors argue that the influence exerted on the participant through virtual simulation is based on the deception of making them believe that they are someone else when this is impossible. This makes the use of VR for empathy enhancement a manipulative strategy in itself. In this article, we show that Ramirez et al.’s ethical (...) rejection of empathy enhancement through VR is based on confusion. First, we show that this misunderstanding stems from the conception of empathy-enhancing simulations solely as failed attempts at “being someone else,” along with ignoring the crucial difference between the psychological perspective-taking processes of imagine-other and imagine-self. Then, having overcome that misconception, we argue that the ethical misgivings about the use of VR to promote empathy should disappear and that these projects have greater potential for behavioural change than purely sympathy-focused interventions.

The history of humankind is full of examples that indicate a constant desire to make human beings more moral. Nowadays, technological breakthroughs might have a significant impact on our moral character and abilities. This is the case of Virtual Reality (VR) technologies. The aim of this paper is to consider the ethical aspects of the use of VR in enhancing empathy. First, we will offer an introduction to VR, explaining its fundamental features, devices and concepts. Then, we will approach the (...) characterization of VR as an “empathy machine,” showing why this medium has aroused so much interest and why, nevertheless, we do not believe it is the ideal way to enhance empathy. As an alternative, we will consider fostering empathy-related abilities through virtual embodiment in avatars. In the conclusion, however, we will, we will examine some of the serious concerns related to the ethical relevance of empathy and will defend the philosophical case for a reason-guided empathy, also suggesting specific guidelines for possible future developments of empathy enhancement projects through VR embodied experiences.

The increasing application of artificial intelligence (AI) to healthcare raises both hope and ethical concerns. Some advanced machine learning methods provide accurate clinical predictions at the expense of a significant lack of explainability. Alex John London has defended that accuracy is a more important value than explainability in AI medicine. In this article, we locate the trade-off between accurate performance and explainable algorithms in the context of distributive justice. We acknowledge that accuracy is cardinal from outcome-oriented justice because it helps (...) to maximize patients’ benefits and optimizes limited resources. However, we claim that the opaqueness of the algorithmic black box and its absence of explainability threatens core commitments of procedural fairness such as accountability, avoidance of bias, and transparency. To illustrate this, we discuss liver transplantation as a case of critical medical resources in which the lack of explainability in AI-based allocation algorithms is procedurally unfair. Finally, we provide a number of ethical recommendations for when considering the use of unexplainable algorithms in the distribution of health-related resources. (shrink)

Digital COVID certificates are a novel public health policy to tackle the COVID-19 pandemic. These immunity certificates aim to incentivize vaccination and to deny international travel or access to essential spaces to those who are unable to prove that they are not infectious. In this article, we start by describing immunity certificates and highlighting their differences from vaccination certificates. Then, we focus on the ethical, legal, and social issues involved in their use, namely autonomy and consent, data protection, equity, and (...) international mobility from a global fairness perspective. The main conclusion of our analysis is that digital COVID certificates are only acceptable if they meet certain conditions: that they should not process personal data beyond what is strictly necessary for the aimed goals, that equal access to them should be guaranteed, and that they should not restrict people’s autonomy to access places where contagion is unlikely. We conclude that, if such conditions are guaranteed, digital COVID certificates could contribute to mitigating some of the most severe socioeconomic consequences of the pandemic. (shrink)

The essay aims to illuminate the current crisis, as it has been diagnosed by important currents of contemporary European thought, from the baroque remarkably the Hispanic perspective. The author argues that one of the fundamental figures of the Baroque is what he calls an infinite aporethic difference. According to this, Baroque understands the world as a set of differences that bind aporethically tending to infinity. This figure is, at the same time, shown as a critical operator with regard to reality, (...) which has lost its pre-modern configuration as Cosmos. The author also holds that in its present projection, the figure of the infinite aporethic difference takes the form of a new normativity, namely, that of the Chaosmos, which is particularly visible in post-structuralism and in the Ibero-American Neo-baroque. By its virtue, it is possible to distinguish two ways of coping with the current crisis. The chaosmotic one would be characteristic of a compromised strong trans-modernity, which contrasts with the evasive weak postmodernity. This problem is finally investigated from the point of view of the subtle baroque heroism and its shadow in the present. (shrink)

The historical background of the 19th century electromagnetic theory is revisited from the standpoint of the opposition between alternative approaches in respect to the problem of interactions. The 19th century electrodynamics became the battle-field of a paramount importance to test existing conceptions of interactions. Hertz’s experiments were designed to bring a solid experimental evidence in favor of one of them. The modern scientific method applied to analyze Hertz’s experimental approach as well as the analysis of his laboratory notes, dairy and (...) private letters show that Hertz’s ‘‘crucial’’ experiments cannot be considered as conclusive at many points as it is generally implied. We found that alternative Helmholtz’s electrodynamics did not contradict any of Hertz’s experimental observations of transverse components as Maxwell’s theory predicted. Moreover, as we now know from recently published Hertz’s dairy and private notes, his first experimental results indicated clearly on infinite rate of propagation. Nevertheless, Hertz’s experiments provided no further explicit information on non-local longitudinal components which were such an essential feature of Helmholtz’s theory. Necessary and sufficient conditions for a decisive choice on the adequate account of electromagnetic interactions are discussed from the position of modern scientific method. (shrink)

Transhumanism is a challenging movement that invites us to rethink what defines humanity, including what we value and regret the most about our existence. Vulnerability is a key concept that require thorough philosophical scrutiny concerning transhumanist proposals. Vulnerability can refer to a universal condition of human life or, rather, to the specific exposure to certain harms due to particular situations. Even if we are all vulnerable in the first sense, there are also different sources and levels of vulnerability depending on (...) concrete social circumstances. Recently, Michael Hauskeller argued about a fundamental incompatibility between transhumanism and vulnerability. He understands vulnerability as an existential category, linked to woundability and mortality. This idea is akin to ontological vulnerability, but it does not notice some important features of social vulnerability. On the other side, transhumanism is a complex and non-homogeneous movement. Here we distinguish between a strong and a weak version of transhumanism. We will propose that the salience of vulnerability is only diminished in the radical one, while a moderate version can reconcile vulnerability with human enhancement. Thus, vulnerability, a concept that has recently gained much importance as an anthropological category in contemporary ethics, is not necessarily at odds with any transhumanist project. (shrink)

In their recent article, Brown et al analyse several ethical aspects around immunity passports and put forward some recommendations for implementing them. Although they offer a comprehensive perspective, they overlook two essential aspects. First, while the authors consider the possibility that immunological passports may appear to discriminate against those who do not possess them, the opposite viewpoint of immune people is underdeveloped. We argue that if a person has been tested positive for and recovered from COVID-19, becoming immune to it, (...) she cannot be considered a hazard to public health and, therefore, the curtailment of her fundamental rights is not legitimate. Second, they omit that vaccine distribution will create similar problems related to immunity-based licenses. Vaccine certificates will de facto generate a sort of immunity passport. In the next phases of the pandemic, different immunity statuses will be at stake, because the need to identify who can spread COVID-19 is unavoidable. If a person does not pose a threat to public health because she cannot spread the infection, then her right to freedom of movement should be respected, regardless of how she acquired that immunity.

Tackling climate change is one of the most demanding challenges of humanity in the 21st century. Still, the efforts to mitigate the current environmental crisis do not seem enough to deal with the increased existential risks for the human and other species. Persson and Savulescu have proposed that our evolutionarily forged moral psychology is one of the impediments to facing as enormous a problem as global warming. They suggested that if we want to address properly some of the most pressing (...) problems that cause catastrophic harm to our existence, we should enhance our moral behavior by biomedical means. The objective of this paper is, precisely, to reflect on whether a Moral Bio-Enhancement (henceforth MBE) program would be a viable option to confront the climate emergency. To meet this goal, I will propose the Ultimate Mostropic (hereafter UM) thought experiment, a hypothetical situation where we have already discovered the UM, an available, safe (without any deleterious secondary effects), extremely cheap and effective pill to enhance our cognitive, affective and motivational abilities related to morality. After briefly presenting the main argument of Persson and Savulescu regarding MBE and climate change, I will point out some of the difficulties that make MBE a daunting but exciting philosophical and scientific debate. In order to overcome these complications, I will describe the UM thought experiment, which involves two scenarios of the MBE program: (a) the state-driven, compulsory and universal enterprise, and (b) the initiative of voluntary individuals. I will show that the shortcomings of MBE programs through the UM in both scenarios make Persson and Savulescu’s proposal a not appealing pathway to mitigate climate change. In the final section, I will suggest that an inaccurate attribution of responsibilities underlies their proposal and that the collective inaction problem should be redirected primarily through a reinforcement of the political nature of the solutions.

The local aspect of the thermalization of thermal radiation due to the interaction of thermal radiation with matter is explored. It is shown that for absorption and emission interactions some well-known phenomenological statements of irreversible thermophysics are indeed relevant.

The local analysis is based on the concepts of temperature and entropy of nonequilibrium thermal radiation fields, as originally introduced by Planck, and shows that these concepts are susceptible (...) of a very natural thermodynamic interpretation.

Close insight into mathematical and conceptual structure of classical field theories shows serious inconsistencies in their common basis. In other words, we claim in this work to have come across two severe mathematical blunders in the very foundations of theoretical hydrodynamics. One of the defects concerns the traditional treatment of time derivatives in Eulerian hydrodynamic description. The other one resides in the conventional demonstration of the so-called Convection Theorem. Both approaches are thought to be necessary for cross-verification of the standard (...) differential form of continuity equation. Any revision of these fundamental results might have important implications for all classical field theories. Rigorous reconsideration of time derivatives in Eulerian description shows that it evokes Minkowski metric for any flow field domain without any previous postulation. Mathematical approach is developed within the framework of congruences for general four-dimensional differentiable manifold and the final result is formulated in form of a theorem. A modified version of the Convection Theorem provides a necessary cross-verification for a reconsidered differential form of continuity equation. Although the approach is developed for one-component (scalar) flow field, it can be easily generalized to any tensor field. Some possible implications for classical electrodynamics are also explored.
