Supernumerary B chromosomes are dispensable elements of the genome which can be retained in populations at high frequencies, despite being deleterious, through the ability to undergo non‐Mendelian inheritance. Their mode of origin is, however, obscure. Recent work on gynogenetic fish has demonstrated the incorporation of small, unstable, centromere‐containing microchromosomes, probably of interspecific derivation, into an asexual lineage(1). That these resemble B chromosomes both in structure and behaviour is consistent with the proposal that hybridisation between closely related species may be a (...) significant mode of origin for such selfish genetic elements. Additional work on the B chromosome of a parasitoid wasp and observations on patterns of chromosome breakage from somatic cell hybrids also support this hypothesis. (shrink)

While philosophers hold that it is patently absurd to blame robots or hold them morally responsible [1], a series of recent empirical studies suggest that people do ascribe blame to AI systems and robots in certain contexts [2]. This is disconcerting: Blame might be shifted from the owners, users or designers of AI systems to the systems themselves, leading to the diminished accountability of the responsible human agents [3]. In this paper, we explore one of the potential underlying reasons for (...) robot blame, namely the folk's willingness to ascribe inculpating mental states or "mens rea" to robots. In a vignette-based experiment (N=513), we presented participants with a situation in which an agent knowingly runs the risk of bringing about substantial harm. We manipulated agent type (human v. group agent v. AI-driven robot) and outcome (neutral v. bad), and measured both moral judgment (wrongness of the action and blameworthiness of the agent) and mental states attributed to the agent (recklessness and the desire to inflict harm). We found that (i) judgments of wrongness and blame were relatively similar across agent types, possibly because (ii) attributions of mental states were, as suspected, similar across agent types. This raised the question - also explored in the experiment - whether people attribute knowledge and desire to robots in a merely metaphorical way (e.g., the robot "knew" rather than really knew). However, (iii), according to our data people were unwilling to downgrade to mens rea in a merely metaphorical sense when given the chance. Finally, (iv), we report a surprising and novel finding, which we call the inverse outcome effect on robot blame: People were less willing to blame artificial agents for bad outcomes than for neutral outcomes. This suggests that they are implicitly aware of the dangers of overattributing blame to robots when harm comes to pass, such as inappropriately letting the responsible human agent off the moral hook.

"Divination and Human Nature" casts a new perspective on the rich tradition of ancient divination--the reading of divine signs in oracles, omens, and dreams. Popular attitudes during classical antiquity saw these readings as signs from the gods while modern scholars have treated such beliefs as primitive superstitions. In this book, Peter Struck reveals instead that such phenomena provoked an entirely different accounting from the ancient philosophers. These philosophers produced subtle studies into what was an odd but observable fact--that humans could (...) sometimes have uncanny insights--and their work signifies an early chapter in the cognitive history of intuition. Examining the writings of Plato, Aristotle, the Stoics, and the Neoplatonists, Struck demonstrates that they all observed how, setting aside the charlatans and swindlers, some people had premonitions defying the typical bounds of rationality. Given the wide differences among these ancient thinkers, Struck notes that they converged on seeing this surplus insight as an artifact of human nature, projections produced under specific conditions by our physiology. For the philosophers, such unexplained insights invited a speculative search for an alternative and more naturalistic system of cognition. Recovering a lost piece of an ancient tradition, "Divination and Human Nature" illustrates how philosophers of the classical era interpreted the phenomena of divination as a practice closer to intuition and instinct than magic.

What role does the imagination play in scientific progress? After examining several studies in cognitive science, I argue that one thing the imagination does is help to increase scientific understanding, which is itself indispensable for scientific progress. Then, I sketch a transcendental justification of the role of imagination in this process.

Both the concept of a Darwinian tree of life (TOL) and the possibility of its accurate reconstruction have been much criticized. Criticisms mostly revolve around the extensive occurrence of lateral gene transfer (LGT), instances of uptake of complete organisms to become organelles (with the associated subsequent gene transfer to the nucleus), as well as the implications of more subtle aspects of the biological species concept. Here we argue that none of these criticisms are sufficient to abandon the valuable TOL concept (...) and the biological realities it captures. Especially important is the need to conceptually distinguish between organismal trees and gene trees, which necessitates incorporating insights of widely occurring LGT into modern evolutionary theory. We demonstrate that all criticisms, while based on important new findings, do not invalidate the TOL. After considering the implications of these new insights, we find that the contours of evolution are best represented by a TOL. (shrink)

Мета. Актуалізувати питання про використання біографічного методу і встановлення його взаємозв'язку з іншими науковими методами та методологічними принципами в історико-антропологічних дослідженнях. Теоретичний базис. Розгляд біографічного методу в історико-антропологічних студіях здійснений у річищі загального теоретичного «ренесансу» класичної гуманітаристики, що значною мірою викликаний невизначеністю і багатозначністю теоретичних дискурсів і дискурсивних практик постмодернізму, висуває перед дослідником низку нових завдань, серед яких – «виявлення неявного», тобто не простого описування результатів культурної діяльності людини в безпосередній даності, а розкривання часом неусвідомлених механізмів цієї діяльності, глибинних «пружин» (...) культури, що забезпечують її рух. Наукова новизна. Автори даної розвідки не торкаються соціологічної проблематики біографічних досліджень, які широко репрезентовані в працях сучасних західних дослідників. Предмет нашого повідомлення – біографічний метод, що є генетично висхідним від Ш.-О. Сент-Бева, який вважав, що головним завданням біографа є здійснення аналізу особистості видатної людини. Очевидність того факту, що дослідження в царині гуманітаристики загалом і в цивільній історії зокрема мають враховувати не тільки зміни соціокультурних аспектів буття, але й відповідну трансформацію методологічних підходів до аналізу епіфеноменів «текучої сучасності», привела нас до розуміння необхідності історіософського дослідження питання про рецепцію біографічного методу в історико-антропологічних працях з наступною історичною, філософською, культурологічною репрезентацією біографічного методу. Висновки. Історіософські трансформації останніх десятиліть з їх радикальною зміною концепцій, методів і прийомів повертають дослідника до вдосконалення біографічної методології, яка сьогодні репрезентує антропоцентризм, що наповнює науку гуманістичним змістом. Використання даної методології потребує від науковця дотримання основних методологічних принципів і оволодіння іншими науковими методами, насамперед діалектикою. (shrink)

Abū al-Ḥajj¿j Yūsuf b. Muḥammad Ibn Ṭumlūs (Alhagiag Bin Thalmus, d. 620/1223) was a philosopher, physician and direct disciple of Ibn Rushd (Averroes, d. 595/1198), who lived and practiced rational sciences in Alzira and Marrakesh, a quarter of a century after the demise of his teacher. Ibn Ṭumlūs was not Ibn Rushd's only student who engaged in work on logic, but one of dozens of disciples, suggesting that the supposed simultaneous death of the latter's philosophy is "grossly exaggerated". As a (...) valuable window into the practice of logic in 13th century al-Andalus and the Maghreb, Ibn Ṭumlūs' Compendium on Logic (Al-Mukhtaṣar fī al-manṭiq) covers all the parts of "the expanded Organon", as it was known since al-F¿r¿bī (d. 339/951). The present volume offers a complete critical Arabic edition of this work, with an English and Arabic introduction, notes and indices. (shrink)

With Western cultures becoming more pluralistic, the question of "truth" in politics has become a game of interpretations. Today, we face the demise of the very idea of truth as an objective description of facts, though many have yet to acknowledge that this is changing. Gianni Vattimo explicitly engages with the important consequences for democracy of our changing conception of politics and truth, such as a growing reluctance to ground politics in science, economics, and technology. Yet in Vattimo's conception, a (...) farewell to truth can benefit democracy, exposing the unspoken issues that underlie all objective claims. The end of absolute truth challenges the legitimacy of policies based on perceived objective necessities—protecting the free market, for example, even if it devastates certain groups or classes. Vattimo calls for a truth that is constructed with consensus and a respect for the liberty of all. By taking into account the cultural paradigms of others, a more "truthful" society—freer and more democratic—becomes possible. In this book, Vattimo continues his reinterpretation of Christianity as a religion of charity and hope, freeing society from authoritarian, metaphysical dogmatism. He also extends Nietzsche's "death of God" to the death of an authoritarian God, ushering in a new, postreligious Christianity. He connects the thought of Martin Heidegger, Karl Marx, and Karl Popper with surprising results and accommodates modern science more than in his previous work, reconciling its validity with an insistence that knowledge is interpretive. Vattimo's philosophy justifies Western nihilism in its capacity to dispense with absolute truths. Ranging over politics, ethics, religion, and the history of philosophy, his reflections contribute deeply to a modern reconception of God, metaphysics, and the purpose of reality. (shrink)

"This is an excellent textbook on Neoplatonism which gives the reader a very concise and lucid overview of the basic doctrines and leading thinkers of the last great philosophy to emerge before the Christianization of the Roman Empire. I’ve no doubt that my students next semester will benefit from the analyses contained in the book. The contents of the chapters are very informative and adequately place developments in their socio-cultural context." --Michael B. Simmons, Auburn University at Montgomery.

Biography of Madhusūdana Sarasvatī, Advaita philosopher.

At the very beginning of L’Homme-Machine, La Mettrie claims that Leibnizians with their monads have “rather spiritualized matter than materialized the soul”; a few years later Pierre-Louis Moreau de Maupertuis, President of the Berlin Academy of Sciences and natural philosopher with a strong interest in the modes of transmission of ‘genetic’ information, conceived of living minima which he termed molecules, “endowed with desire, memory and intelligence,” in his Système de la nature ou Essai sur les corps organisés. This text first (...) appeared in Latin in 1751 under the title Dissertatio inauguralis metaphysica de universali naturae systemate, with the pseudonym Dr Baumann; it was translated by Maupertuis in 1754 as Essai sur la formation des corps organisés and was later included in his 1756 Œuvres under the title Système de la nature. Now, it is clear that Maupertuis was a kind of Leibnizian; and that his molecule possessed higher-level, ‘mental’ properties. In that sense he falls under the first category described by La Mettrie. But he was also involved in a debate on this issue with Diderot, who put forth a sustained critique of Maupertuis’ theory of the molecule in the additions to his 1753 Pensées sur l’interprétation de la nature. Where Maupertuis attributes higher-level properties to his living minima, Diderot argues that these properties are ‘organizational’, i.e., they can only be properties of the whole. At issue here is the degree of commitment to a form of materialism. (shrink)

Colour constancy refers to the ability to extract information about surface colours independently of illumination conditions. A ripe strawberry, for example, appears the same red when viewed under a blue sky or a reddish sunset. Since Land's pioneering work, discussion has centred on the issue whether colour constancy is achieved primarily in the retina or visual cortex. Recently, the debate has shifted to a consideration of the constraints imposed by various psychophysical tasks and instructions. Humans can judge illuminant colour, reflected-light (...) colour, surface colour, and the relationship between surface colours within a scene. Such observations suggest that colour constancy may not be a unitary phenomenon, and that its different aspects may be mediated at different levels in the visual system. Several questions therefore arise: are the tasks of surface estimation and illuminant estimation complementary, insofar as good performance in one implies poor performance in the other? How does retinal adaptation alter performance? Is colour vision tuned to the statistical composition of natural surfaces and illuminants? What role does colour-opponent processing in retina and cortex play in colour constancy? These and related questions are explored here in order to better understand what we mean when we ask: "Why do strawberries look red?". (shrink)
