La edición genética tiene muchas aplicaciones en casi todos los ámbitos de la sociedad, pero también puede tener consecuencias impredecibles. La edición del genoma de la línea germinal humana es el centro de una discusión mundial. Debido al creciente número de cuestionamientos científicos, éticos y políticos, muchos sin una respuesta concreta, el consenso de la comunidad científica manifiesta que sería inapropiado modificar genéticamente embriones humanos. Se considera necesario un debate serio y abierto para decidir si se debe suspender o fomentar (...) la investigación en este sentido. En el presente documento, se exponen algunos argumentos audaces a favor de la eliminación de los genes nocivos del genoma humano y los riesgos que supone el eugenismo liberal. (shrink)

The brain displays both the anatomical features of a vast amount of interconnected topological mappings as well as the functional features of a nonlinear, metastable system at the edge of chaos, equipped with a phase space where mental random walks tend towards lower energetic basins. Nevertheless, with the exception of some advanced neuro-anatomic descriptions and present-day connectomic research, very few studies have been addressing the topological path of a brain embedded or embodied in its external and internal environment. Herein, by (...) using new formal tools derived from algebraic topology, we provide an account of the metastable brain, based on the neuro-scientific model of Operational Architectonics of brain-mind functioning. We introduce a “topodynamic” description that shows how the relationships among the countless intertwined spatio-temporal levels of brain functioning can be assessed in terms of projections and mappings that take place on abstract structures, equipped with different dimensions, curvatures and energetic constraints. Such a topodynamical approach, apart from providing a biologically plausible model of brain function that can be operationalized, is also able to tackle the issue of a long-standing dichotomy: it throws indeed a bridge between the subjective, immediate datum of the naïve complex of sensations and mentations and the objective, quantitative, data extracted from experimental neuro-scientific procedures. Importantly, it opens the door to a series of new predictions and future directions of advancement for neuroscientific research. (shrink)

O pesquisador americano Joseph Banks Rhine (1895 – 1980) e o psiquiatra suíço Carl Gustav Jung (1875 – 1961) foram contemporâneos, o interesse mútuo de pesquisa levou os dois autores a estabeleceram uma troca de correspondências a partir de 1934, que duraria as duas décadas seguintes.

First of all, we would like to gratefully thank all commentators for the attention and effort they have put into reading and responding to our review paper [this issue] and for useful observations that suggest novel applications for our framework. We understand and accept that some of our claims might appear controversial and raise skepticism, because the overall neural framework we have proposed is difficult to frame in established categories, given its strong multidisciplinary character. To make an example, Elsevier is (...) publishing the British Neuroscience Association (BNA) 2017 Special Issue Collection. However, our paper could not fully fit in any of their Special Issues—attention, motivation, behavior; sensory and motor systems; novel treatments and translational neuroscience; genetics and epigenetics; learning and memory; neurodegenerative disorders and ageing; developmental neuroscience; neuronal, glial and cellular mechanisms; neuroendocrine and autonomic nervous systems; psychiatry and mental health; methods and techniques. Perhaps because our paper was mathematically, physically, biologically (neuroscientifically), and phenomenologically motivated from the start? Nevertheless, venturing in novel, fresh, testable proposals is badly needed in contemporary neuroscience, so to break into “the utter darkness of the inner mechanism of psychic acts… during the production of the concomitant phenomena of perception and thought, namely, feelings, consciousness and volition”—as Cajal had already observed in his opus magnus ‘Textura’. But as he soberly confessed: “This ideal is still very distant” (Ramon y Cajal, 1899-1904, p. 1,141). In the pursuit of that very ideal, neuroscience and psychology have had, and continue to have, a plethora of movements and schools of thought: behaviorism, cognitivism, neural Darwinism, social constructivism, Bayesian optimization...In our paper, we propose to go a step further, via the notion of topodynamics, towards “projectionism.” In what follows, trying to elucidate the main features of this Emperor’s new clothing, we proceed with the responses to the comments received.

Dicho proyecto es denominado por Laín “pleisología de la vida cotidiana”; (...) tal propuesta resulta necesaria y debe ser acogida por el cristianismo en nuestros días. Se hace perentorio, hacer del cristianismo una propuesta con sentido, para ello, quien se quiera cristiano, que asuma su modo de serlo como vocación y la formule como un proyecto personal (sea persona), responsable y desde allí contribuya a la humanización de las relaciones humanas mediante la práctica de un amor samaritano.

The importance of an author can be evaluated by the extent to which his theoretical contribution transforms a certain area of knowledge: major researchers create new vistas. This certainly applies to Lev Vygotsky (1896–1934), one of the most brilliant authors of contemporary psychology.

The relationship between gender and ethics has been extensively researched. However, previous studies have assumed that the gender–ethics association is constant; hence, scholars have seldom investigated factors potentially affecting the gender–ethics association. Thus, using managers as the research target, this study examined the relationship between gender and ethics and analyzed the moderating effect of cultural values on the gender–ethics association. The results showed that, compared with female managers, their male counterparts are more willing to justify business-related unethical behaviors such as (...) bribery and tax evasion, and that the gender difference in ethics becomes more pronounced under the cultural dimensions of collectivism, humane orientation, performance orientation, and gender egalitarianism. This study used data obtained through surveying 2,754 managers in 27 nations. (shrink)

The purpose of the present study is to examine the attitudes of Portuguese chartered accountants with respect to questions of ethical nature that can arise in their professional activity. Respondents were asked to respond to the Ethics Position Questionnaire developed by Forsyth (Journal of Personality and Social Psychology 39(1), 175–184, 1980), in order to determine their idealism and relativism levels. Subsequently, they answered questions about five scenarios related to accounting practices, with the objective of measuring their ethical judgments. Based on (...) the idealism and relativism levels of our respondents, they were classified into one of four groups, representing different ethical ideologies (absolutism, exceptionism, subjectivism, and situationism). The results indicated that age was the major determinant of relativism. Contrary to previous research, older respondents revealed themselves significantly more relativistic than younger ones. Gender seems to be the most important determinant of ethical judgments; against expectations, men evidenced significantly stricter judgments than women in two of the five scenarios. Findings also indicated that respondents’ ethical judgments did not differ significantly based on their ethical ideology, supporting the idea that ethical ideology is not an important determinant of ethical judgments.

This Is A New Release Of The Original 1868 Edition.

What is honor? Has its meaning changed since ancient times? Is it an outmoded notion? Does it still have the power to direct our behavior? In this provocative book Alexander Welsh considers the history and meaning of honor and dismisses the idea that we live in a post-honor culture. He notes that we have words other than _honor_, such as _respect_, _self-respect_, and personal _identity_, that show we do indeed care deeply about honor. Honor, he argues, is a continuing (...) process of respect that motivates or constrains members of a peer group. Honor’s dictates function as moral imperatives. Surprisingly, little systematic study of the history of honor in Western culture has been attempted. Offering a welcome remedy, Welsh provides a genealogy of approaches to the subject, mining some of the most influential texts of the Western tradition. He rereads with fascinating results the works of Aristotle, Cicero, Shakespeare, Mandeville, Montesquieu, Rousseau, Kant, Adam Smith, and others. With a sharp focus on the intersection of honor and ethics in both literature and philosophy, Welsh invites new and constructive debate on a topic of vital interest. (shrink)

Much has been written on whether practical knowledge (knowledge-how) reduces to propositional knowledge (knowledge-that). Less attention has been paid to what we call deliberative knowledge (knowledge-to), i.e., knowledge ascriptions embedding other infinitival questions, like _where to meet_, _when to leave_, and _what to bring_. We offer an analysis of knowledge-to and argue on its basis that, regardless of whether knowledge-how reduces to knowledge-that, no such reduction of knowledge-to is forthcoming. Knowledge-to, unlike knowledge-that and knowledge-how, requires the agent to have formed (...) certain conditional intentions. We discuss the philosophical implications for knowledge-how, deliberative questions, and virtue. (shrink)

In light of the problem of logical omniscience, some scholars have argued that belief is question-sensitive: agents don't simply believe propositions but rather believe answers to questions. Hoek (2022) has recently developed a version of this approach on which a belief state is a "web" of questions and answers. Here, we present several challenges to Hoek's question-sensitive account of belief. First, Hoek's account is prone to very similar logical omniscience problems as those he claims to address. Second, the link between (...) belief and action he proposes is too rigid. We close by sketching a generalization of the account that can meet these challenges. (shrink)

The medial prefrontal cortex (mPFC) has been the subject of intense interest as a locus of cognitive control. Several computational models have been proposed to account for a range of effects, including error detection, conflict monitoring, error likelihood prediction, and numerous other effects observed with single-unit neurophysiology, fMRI, and lesion studies. Here, we review the state of computational models of cognitive control and offer a new theoretical synthesis of the mPFC as signaling response–outcome predictions. This new synthesis has two interacting (...) components. The first component learns to predict the various possible outcomes of a planned action, and the second component detects discrepancies between the actual and intended responses; the detected discrepancies in turn update the outcome predictions. This single construct is consistent with a wide array of performance monitoring effects in mPFC and suggests a unifying account of the cognitive role of medial PFC in performance monitoring.

In this paper I assess the adequacy of no-conspiracy conditions employed in the usual derivations of the Bell inequality in the context of EPR correlations. First, I look at the EPR correlations from a purely phenomenological point of view and claim that common cause explanations of these cannot be ruled out. I argue that an appropriate common cause explanation requires that no-conspiracy conditions are reinterpreted as mere common cause-measurement independence conditions. In the right circumstances then, violations of measurement independence need (...) not entail any kind of conspiracy (nor backwards in time causation). To the contrary, if measurement operations in the EPR context are taken to be causally relevant in a specific way to the experiment outcomes, their explicit causal role provides the grounds for a common cause explanation of the corresponding correlations.

We explore Peirce’s pragmatic conception of sign action, as a distributed and emergent view of cognition and exemplify with the emergence of classical ballet. In our approach, semiosis is a temporally distributed process in which a regular tendency towards certain future outcomes emerges out of a history of sign actions. Semiosis self-organizes in time, in a process that continuously entails the production of more signs. Emergence is a ubiquitous condition in this process: the translation of signs into signs cannot be (...) inferred from the properties of the components of a semiotic triad alone, but has to take into account a complex interaction between a micro-semiotic and macro-semiotic level of description. This interaction can be understood as an interplay of potentialities and tendencies, or upward constitutive determinative relations and downward selective determinative relations. According to this view, emergence is a central defining condition of processes of meaning. Ballet is a sign in action. The emergence of classical ballet is a self-regulatory process, in which a system of different kinds of cognitive artifacts (musical, bodily/motor, spatial/architectonic) and agents obtained a stable semiotic relation throughout many phases of development between the 16th and the 19th Century. One case is the development of the verticality of dance in classical ballet as a semiotic relation connecting proscenium arch stages, dancing bodies, and audiences. This development is micro-semiotically determined by the spatial constraints of the proscenium arch stage, and macro-semiotically determined by a historical construction of the dancing body as a sign within a network of semiotic chains, such as the intersemiotic regulation of body of the dancer by principles coming from painting. This is not only the emergence of actual meaning, but also the emergence of an open-ended field of potential and general meanings, an autonomous tendency of development. To say that ballet, as sign action, emerges, is to say that cognitive artifacts such as dancer’s bodies, stages and audience’s point of view, musical compositions, costumes, all sorts of supporting institutions, etc, constitute a niche for sign action, interacting according to tendencies of development that didn’t exist before.

We present a novel semantic and conversational framework for a class of gradable-like constructions. These include metalinguistic comparatives, like "Ann is more a linguist than a philosopher", as well as metalinguistic equatives, degree modifications, and conditionals. To the extent previous literature discusses such metalinguistic gradability, the focus has been on comparatives. We extend our account of metalinguistic comparatives (Rudolph & Kocurek 2020) to cover a broader range of metalinguistic gradable constructions. On our semantic expressivist view, these all serve in various (...) ways to express speakers' relative commitments to different linguistic interpretations. (shrink)

We advance two objections to the selfish gene theory formulated by Richard Dawkins, which states that natural selection operates on genetic replicators. These objections target three of the essential features of the theory. The first feature is the exclusivity that the theory ascribes to genetic replicators as objects of natural selection. We call it “the exclusivity clause”. The second and third features correspond to two criteria that genetic replicators must satisfy for Dawkins’ theory to hold. We call them “the stability (...) criterion” and “the fidelity criterion”. The first objection we advance is that, given the findings of transgenerational epigenetics, genetic replicators do not appear to satisfy the exclusivity clause and some of them do not seem to meet the stability criterion. The second objection is that the existence of the molecular phenomena known as alternative splicing and trans-splicing seems to entail that many genetic replicators do not satisfy neither the stability criterion nor the fidelity criterion.

The methodological differences of understanding, versus explaining, have been at the centre of a century-long methodenstreit debate (and disagreement) among philosophers and scientists. Karl Jaspers managed to import this discussion to the realm of psychiatry and psychopathology in a significant, but unresolved, manner. Side-tracked by the advent of various changes in psychiatry during the 20th century, phenomenology and philosophy of psychiatry have made a comeback in the last decades and, since then, developed new contributions to this subject. Quite similarly, the (...) study of time experience, standing on the shoulders of notorious philosophers, has too witnessed a similar renaissance, with groundbreaking developments across several conditions, including depression. The present essay is essentially exploratory, but during its development, after addressing the concepts of the methodenstreit debate, and tackling both meaningful and causal connections behind time dysperception in depression, I argue that understanding, at least in this context and at present time, is not entirely reducible to causal explanations, for some things are only gained in understanding, such as the feeling of being understood and the implications it carries for a therapeutic relationship and the treatment plan.

Alternative cleavage and polyadenylation (APA) can diversify coding and non‐coding regions, but has particular impact on increasing 3′ UTR diversity. Through the gain or loss of regulatory elements such as RNA binding protein and microRNA sites, APA can influence transcript stability, localization, and translational efficiency. Strikingly, the central nervous systems of invertebrate and vertebrate species express a broad range of transcript isoforms bearing extended 3′ UTRs. The molecular mechanism that permits proximal 3′ end bypass in neurons is mysterious, and only (...) beginning to be elucidated. This landscape of neural 3′ UTR extensions, many reaching unprecedented lengths, may help service the unique post‐transcriptional regulatory needs of neurons. A combination of approaches, including transcriptome‐wide profiling, genetic screening to identify APA factors, biochemical dissection of alternative 3′ end formation, and manipulation of individual neural APA targets, will be necessary to gain fuller perspectives on the mechanism and biology of neural‐specific 3′ UTR lengthening.

The main purpose of this work is to provide a semiotic ontology for redescription of active cognitive externalism, recently developed by the paradigm 4E (embodied, embedded, enactive, extended cognition). In our approach, distributed cognitive systems (DCSs) are described as semiosis, signs in action. We explored the relationship between semiosis and cognition, as conceived by C. S. Peirce, in association with the notion of distributed cognitive system (DCS). We introduce Peircean externalist approach with an emphasis on the notion of temporal distribution (...) of semiosis, and describe DCSs, and their elements, as “sign in action”. To develop this argument, we describe an example of DCS -- verbal-musical improvisation of repente, repentismo, or viola singing. It is a phenomenon of verbal-musical improvisation that takes the form of a challenge in versified oral poetry. We describe the phenomenon as the embodiment of the formal structure of a cognitive task and an inferential process. This embodiment corresponds to a semiotization of the repente performances as DCSs. The temporally distributed tendency of repentismo organizes the DCS as a system that performs metasemiotic experiments on the action of signs. (shrink)

Appeals to human nature are ubiquitous, yet historically many have proven ill-founded. Why? How might frequent errors be remedied towards building a more robust and reliable scientific study of human nature? Our aim is neither to advance specific scientific or philosophical claims about human nature, nor to proscribe or eliminate such claims. Rather, we articulate through examples the types of errors that frequently arise in this field, towards improving the rigor of the scientific and social studies. We seek to analyze (...) such claims rhetorically, cognitively, and epistemically. Namely, how do we think about human nature? Claims about human nature, we show, are susceptible to widely exhibited deficits in cognitive tendencies such as framing, confirmation bias, satisficing, and teleological perspectives, as well as motivated reasoning. Such missteps foster methodological, empirical, and psychological mistakes and biases. Specifically, they promote the naturalizing error, whereby cultural ideology and values are projected onto an apparently objective description of nature. Concrete remedies are offered to aid scientists in conducting and reporting their research goals and findings more responsibly and effectively (relevant also to educators and other communicators who convey these findings publicly). Recommendations include acknowledging that human nature claims are often context-dependent, seeking multiple critical perspectives, and explicitly labeling uncertainties. (shrink)

[Alan Weir] This paper addresses the problem of how to account for objective content-for the distinction between how we actually apply terms and the conditions in which we ought to apply them-from within a naturalistic framework. Though behaviourist or dispositionalist approaches are generally held to be unsuccessful in naturalising objective content or 'normativity', I attempt to restore the credibility of such approaches by sketching a behaviouristic programme for explicating objective content. /// [Alexander Miller] Paul Boghossian (1989, 1990) has argued, (...) on grounds concerning the holistic nature of belief fixation, that there are principled reasons for thinking that 'optimal conditions' versions of reductive dispositionalism about content cannot hope to satisfy a condition of extensional accuracy. I discern three separable strands of argument in Boghossian's work-the circularity objection, the open-endedness objection, and the certification objection-and argue that each of these objections fails. My conclusion is that for all that Boghossian has shown, 'optimal conditions' versions of reductive dispositionalism have to be assessed on a case-by-case basis. (shrink)

Italian translation with facing Greek text of Alexander's commentary on Aristotle's Metaphysics I-V, and of pseudo-Alexander's commentary on the remaining books of the Metaphysics.

"Aristotle was a systematic writer who often cross-referred to the definitions of terms given elsewhere in his work. Book 5 of the Metaphysics is important because it consists of definitions of the main uses of key terms in Aristotle's philosophy, and it is extremely valuable to have a commentary on this important text by Alexander of Aphrodisias, the leading commentator of his school. Alexander provides a detailed commentary on all of the thirty terms analysed in Book 5, weighing (...) alternative interpretations of what Aristotle says one against another, defending Peripatetic views against actual and possible criticisms, and attempting to integrate what is said in Book 5 into the context of the Metaphysics as a whole."--Bloomsbury Publishing.

The last 14 chapters of book 1 of Aristotle's "Prior Analytics" are concerned with the representation in the formal language of syllogistic of propositions and arguments expressed in more or less everyday Greek. In his commentary on those chapters, Alexander of Aphrodisias explains some of Aristotle's more opaque assertions and discusses post-Aristotelian ideas in semantics and the philosophy of language. In doing so he provides an unusual insight into the way in which these disciplines developed in the Hellenistic era. (...) He also shows a more sophisticated understanding of these fields than Aristotle himself, while remaining a staunch defender of Aristotle's emphasis on meaning as opposed to Stoics concern with verbal formulation. In his commentary on the final chapter of book 1 Alexander offers a thorough discussion of Aristotle's distinction between denying that something is, e.g., white and asserting that it is non-white.

Alexander's views on universals are, it seems, quite important in the history of western philosophy. When Boethius gives in his second commentary on Porphyry's Isagoge his solution to the problem of universals as he conceived it, he claims to be adopting Alexander's approach. If true, this means that the locus classicus for all western medieval thinkers on this topic is really a rendering of Alexander's teaching. Alexander commented Aristotle’s statement in his On the Soul “The universal (...) animal either is nothing at all or is posterior if it exists”, and this commentary has been translated into Arabic several times in the classical period. In this study the anonymous Arabic translations of Alexander’s commentary has been translated into English. (shrink)
