The concept that alterated communications between the gut microbiome and the brain may play an important role in human brain disorders has recently received considerable attention. This is the result of provocative preclinical and some clinical evidence supporting early hypotheses about such communication in health and disease. Gastrointestinal symptoms are a common comorbidity in patients with autism spectrum disorders (ASD), even though the underlying mechanisms are largely unknown. In addition, alteration in the composition and metabolic products of the gut microbiome (...) has long been implicated as a possible causative mechanism contributing to ASD pathophysiology, and this hypothesis has been supported by several recently published evidence from rodent models of autism induced by prenatal insults to the mother. Recent evidence in one such model involving maternal infection, that is characterized by alterations in behavior, gut physiology, microbial composition, and related metabolite profile, suggests a possible benefit of probiotic treatment on several of the observed abnormal behaviors.

Henri Lefebvre, em O Direito à Cidade, afirmou que a cidade desde a Idade Clássica foi um objeto especial para o pensamento filosófico: a própria filosofia nasceu na cidade. Outra questão, destacou, seria pensar em um direito à cidade, como direito à vida urbana, transformada, renovada, um direito em formação que ainda não teria entrado nos códigos formalizados. Esse conceito, criado pouco antes de Maio de 1968 e empregado por diversos movimentos sociais desde o fim da década de 1960 até (...) os dias atuais, inclusive no Brasil, foi depois discutido, entre outros autores, por David Harvey. No entanto, esses autores não realizaram exatamente uma articulação com a filosofia do Direito.

This study uses university commentaries on Aristotle's Nicomachean Ethics as a window onto changing ideals and practices of education and of humanist Aristotelianism in Renaissance Italy, particularly in Florence, Padua, Bologna, and Rome (including the Collegio Romano).

In _The Later Middle Ages,_ the third volume of his monumental _History of Political Ideas,_ Eric Voegelin continues his exploration of one of the most crucial periods in the history of political thought. Illuminating the great figures of the high Middle Ages, Voegelin traces the historical momentum of our modern world in the core evocative symbols that constituted medieval civilization. These symbols revolved around the enduring aspiration for the _sacrum imperium,_ the one order capable of embracing the transcendent and immanent, (...) the ecclesiastical and political, the divine and human. The story of the later Middle Ages is that of the "civilizational schism"—the movement in which not only the reality but the aspiration for the _sacrum imperium_ gradually disappeared and the unification of faith and reason dissolved. His recognition of this civilizational schism provides Voegelin with a unique perspective on medieval society. William of Ockham, Dante, Giles of Rome, and Marsilius of Padua all emerge in Voegelin's study as predecessors to modern thought; each turns to personal authority and intellectual analysis in an attempt to comprehend the loss of the _sacrum imperium_ as an authoritative ideal. Voegelin is further drawn into investigations that, despite insufficient attention by scholars, still bear relevance to the study of the later Middle Ages. The mysticism apparent in _Piers Plowman_ and the apocalyptic revolt of Cola di Rienzo are merely two reactions to the disintegration of wholeness. Yet the story of the later Middle Ages does not merely revolve around disintegration. Voegelin recognizes the emergence of the constitutional political tradition as the most positive development of this period. He is at his best when explaining the difference between the presence of a representative institution and the growth of communal consciousness. Voegelin's study of the English political pattern is matched only by his unique perspective on the German imperial zone, culminating in a fitting conclusion on Nicholas of Cusa—the one political thinker with the ability to evoke the unity of mankind beyond fragmentation. _The Later Middle Ages_ is at once a brilliant examination of the symbols that characterized medieval society and a remarkable predecessor to Voegelin's study of the modern world, beginning with the Renaissance and the Reformation.

Using data on the ‘career’ paths of one thousand ‘leading scientists’ from 1450 to 1900, what is conventionally called the ‘rise of modern science’ is mapped as a changing geography of scientific practice in urban networks. Four distinctive networks of scientific practice are identified. A primate network centred on Padua and central and northern Italy in the sixteenth century expands across the Alps to become a polycentric network in the seventeenth century, which in turn dissipates into a weak polycentric (...) network in the eighteenth century. The nineteenth century marks a huge change of scale as a primate network centred on Berlin and dominated by German-speaking universities. These geographies are interpreted as core-producing processes in Wallerstein’s modern world-system; the rise of modern scientific practice is central to the development of structures of knowledge that relate to, but do not mirror, material changes in the system.

As Cary J. Nederman writes in the foreword to this new edition, "Marsilius continues to speak to many of the salient issues of modern political life, expressing his doctrines in a language that has resonance and relevance. Whether in addressing the role of citizenship as a buffer between individual and community, or in explicating the foundations of religious toleration, the _Defensor pacis_ (and Marsilius' other writings) affords a distinctive theoretical perspective that rivals that of any of the great thinkers of (...) the Western political tradition.".

From religion to philosophy to science, all human systems of definition are formed by human brains. The nature and limits of the human brain are the nature and limits of those systems. This essay shows how the human brain works normally then unusually, and what this reveals about the limits of human knowledge. There are many conditions and instances where the brain processes information unusually, including mental disorders, physical events, and drug use. This essay focuses on the neurological events called (...) mystical experiences. (shrink)

O artigo atualiza um tema fundamental da Conferência de Puebla, a opção preferencial pelos pobres, através do diálogo com o tema da aversão pelos pobres, ou aporofobia, estudado pela filósofa Adela Cortina. Apresenta os significados da opção preferencial pelos pobres, inaugurada em Medellín e solenemente proclamada em Puebla e mostra como esta opção foi assumida pelo magistério posterior, tanto na América Latina quanto no magistério universal; em seguida, sistematiza os aspectos da aporofobia ressaltados por Adela Cortina e, ao final, propõe (...) cinco desafios teológico-pastorais: redescobrir a opção pelos pobres como graça, perceber a necessidade do envolvimento emocional com os pobres, descobrir a riqueza dos pobres e recusar o discurso do ódio, refletir sobre caminhos para eliminar a pobreza e contribuir para uma nova economia. Em tudo isto, o magistério de Francisco mostra-se profundamente iluminador. Podemos dizer que, com o Papa Francisco, é aprofundado um caminho profético de inclusão, convivência e responsabilidade globais, que visibiliza e inclui os pobres e, assim, enfrenta a aporofobia.

This paper aims to provide two abductive considerations adducing in favor of the thesis of Necessitism in modal ontology. I demonstrate how instances of the Barcan formula can be witnessed, when the modal operators are interpreted 'naturally' -- i.e., as including geometric possibilities -- and the quantifiers in the formula range over a domain of natural, or concrete, entities and their contingently non-concrete analogues. I argue that, because there are considerations within physics and metaphysical inquiry which corroborate modal relationalist claims (...) concerning the possible geometric structures of spacetime, and dispositional properties are actual possible entities, the condition of being grounded in the concrete is consistent with the Barcan formula; and thus -- in the geometric setting -- merits adoption by the Necessitist.

Why does trust collapse in times of crisis? And when, instead, does it become a driver of growth, generating value? This book offers an analysis of the dynamics of trust through a sociological interpretation of the thought of John Maynard Keynes, the first economist to understand the full extent of the confidence-lever. In the context of the 2007 crisis and following recession, the innovative concept of Economy of Trust explains how trust spontaneously replaces the weakened institutional system of quality assurance (...) and control and generates value. Indeed, the deficiency of such a system has become the ideal breeding ground for the growth of the Nominal Economy: the economy that distorts the perception of reality as it widens economic and social disparities, unbalances relationships between risk and wealth in the global society and dissolves the bonds of responsibility. In this way, trust is channeled towards strong "new powers", such as hedge funds companies, rating agencies and investment banks. Within this context, only targeted policies of Economy of Trust can funnel the 'store of value' effect generated by trust towards positive intents of building social capital. (shrink)

Part of the appeal of the biological approach to personal identity is that it does not have to countenance spatially coincident entities. But if the termination thesis is correct and the organism ceases to exist at death, then it appears that the corpse is a dead body that earlier was a living body and distinct from but spatially coincident with the organism. If the organism is identified with the body, then the unwelcome spatial coincidence could perhaps be avoided. It is (...) argued that such an identification would be a mistake. A living organism has a different part/whole relationship and persistence conditions than the alleged body. A case will be made that the concept ‘human body’ is a conceptual mess, vague in an unprincipled manner, and that an eliminativist stance towards dead bodies is the appropriate response.

This book is a defense of modal realism; the thesis that our world is but one of a plurality of worlds, and that the individuals that inhabit our world are only a few out of all the inhabitants of all the worlds. Lewis argues that the philosophical utility of modal realism is a good reason for believing that it is true.

In the Garden of Eden, we had unmediated contact with the world. We were directly acquainted with objects in the world and with their properties. Objects were simply presented to us without causal mediation, and properties were revealed to us in their true intrinsic glory.

What happens when machines become more intelligent than humans? One view is that this event will be followed by an explosion to ever-greater levels of intelligence, as each generation of machines creates more intelligent machines in turn. This intelligence explosion is now often known as the “singularity”. The basic argument here was set out by the statistician I.J. Good in his 1965 article “Speculations Concerning the First Ultraintelligent Machine”: Let an ultraintelligent machine be defined as a machine that can far (...) surpass all the intellectual activities of any man however clever. Since the design of machines is one of these intellectual activities, an ultraintelligent machine could design even better machines; there would then unquestionably be an “intelligence explosion”, and the intelligence of man would be left far behind. Thus the first ultraintelligent machine is the last invention that man need ever make. The key idea is that a machine that is more intelligent than humans will be better than humans at designing machines. So it will be capable of designing a machine more intelligent than the most intelligent machine that humans can design. So if it is itself designed by humans, it will be capable of designing a machine more intelligent than itself. By similar reasoning, this next machine will also be capable of designing a machine more intelligent than itself. If every machine in turn does what it is capable of, we should expect a sequence of ever more intelligent machines. This intelligence explosion is sometimes combined with another idea, which we might call the “speed explosion”. The argument for a speed explosion starts from the familiar observation that computer processing speed doubles at regular intervals. Suppose that speed doubles every two years and will do so indefinitely. Now suppose that we have human-level artificial intelligence 1 designing new processors. Then faster processing will lead to faster designers and an ever-faster design cycle, leading to a limit point soon afterwards. The argument for a speed explosion was set out by the artificial intelligence researcher Ray Solomonoff in his 1985 article “The Time Scale of Artificial Intelligence”.1 Eliezer Yudkowsky gives a succinct version of the argument in his 1996 article “Staring at the Singularity”: “Computing speed doubles every two subjective years of work..

[This is an edited version of a keynote talk at the conference on Neural Information Processing Systems (NeurIPS) on November 28, 2022, with some minor additions and subtractions.] -/- There has recently been widespread discussion of whether large language models might be sentient or conscious. Should we take this idea seriously? I will break down the strongest reasons for and against. Given mainstream assumptions in the science of consciousness, there are significant obstacles to consciousness in current models: for example, their (...) lack of recurrent processing, a global workspace, and unified agency. At the same time, it is quite possible that these obstacles will be overcome in the next decade or so. I conclude that while it is somewhat unlikely that current large language models are conscious, we should take seriously the possibility that successors to large language models may be conscious in the not-too-distant future.

How should one react when one has a belief, but knows that other people—who have roughly the same evidence as one has, and seem roughly as likely to react to it correctly—disagree? This paper argues that the disagreement of other competent inquirers often requires one to be much less confident in one’s opinions than one would otherwise be.

This volume is devoted to Lewis's work in metaphysics and epistemology. Topics covered include properties, ontology, possibility, truthmaking, probability, the mind-body problem, vision, belief, and knowledge. The purpose of this collection, and the volumes that precede and follow it, is to disseminate more widely the work of an eminent and influential contemporary philosopher. The volume will serve as a useful work of reference for teachers and students of philosophy.

The singularity hypothesis is a radical hypothesis about the future of artificial intelligence on which self-improving artificial agents will quickly become orders of magnitude more intelligent than the average human. Despite the ambitiousness of its claims, the singularity hypothesis has been defended at length by leading philosophers and artificial intelligence researchers. In this paper, I argue that the singularity hypothesis rests on scientifically implausible growth assumptions. I show how leading philosophical defenses of the singularity hypothesis (Chalmers 2010, Bostrom 2014) fail (...) to overcome the case for skepticism. I conclude by drawing out philosophical implications of this discussion for our understanding of consciousness, personal identity, digital minds, existential risk, and ethical longtermism.

A number of philosophers endorse, without argument, the view that there’s something it’s like consciously to think that p, which is distinct from what it’s like consciously to think that q. This thesis, if true, would have important consequences for philosophy of mind and cognitive science. In this paper I offer an argument for it, and attempt to induce examples of it in the reader. The argument claims it would be impossible introspectively to distinguish conscious thoughts with respect to their (...) content if there weren’t something it’s like to think them. This argument is defended against several objections. Then I use what I call “minimal pair” experiences—sentences read without and with understanding—to induce in the reader an experience of the kind I claim exists. Further objections are considered and rebutted. (shrink)

O artigo analisa poemas de Ricardo Domeneck, Eduardo Sterzi, Paulo Ferraz e Priscila Figueiredo, que tratam de questões sobre graves violações de direitos humanos cometidas pelo Estado brasileiro, como a memória dos desaparecidos ou das vítimas da ditadura militar. A análise enquadra-se no campo da literatura e justiça de transição, com o objetivo de estudar o cruzamento entre invenção literária e memória social, no tocante ao legado dos crimes contra a humanidade praticados pelo Estado brasileiro. Todos esses autores nasceram nos (...) anos 1970, durante a ditadura militar no Brasil, que durou de 1964 a 1985. Os poemas analisados foram escritos no século XXI, em um novo ciclo de memória cultural no Brasil, segundo a hipótese de Rebecca Atencio, no qual os temas ligados à ditadura voltaram a ser objeto da literatura brasileira com mais frequência. No caso de Paulo Ferraz, o poema diz respeito à Era Vargas (1930-1945). Domeneck, cujo poema é mencionado no relatório da Comissão Nacional da Verdade, e Sterzi referem-se à ditadura militar. Priscila Figueiredo trata das continuidades do passado autoritário nos crimes do Estado brasileiro após a democratização. Nesses quatro casos, a poética desses autores difere da que argentinos reunidos sob a categoria dos “hijos” têm estabelecido. (shrink)

Conceptual engineering is the design, implementation, and evaluation of concepts. Conceptual engineering includes or should include de novo conceptual engineering (designing a new concept) as well as conceptual re-engineering (fixing an old concept). It should also include heteronymous (different-word) as well as homonymous (same-word) conceptual engineering. I discuss the importance and the difficulty of these sorts of conceptual engineering in philosophy and elsewhere.

"My work has had nothing to do with gay liberation," Michel Foucault reportedly told an admirer in 1975. And indeed there is scarcely more than a passing mention of homosexuality in Foucault's scholarly writings. So why has Foucault, who died of AIDS in 1984, become a powerful source of both personal and political inspiration to an entire generation of gay activists? And why have his political philosophy and his personal life recently come under such withering, normalizing scrutiny by commentators as (...) diverse as Camille Paglia, Richard Mohr, Bruce Bawer, Roger Kimball, and biographer James Miller? David M. Halperin's Saint Foucault is an uncompromising and impassioned defense of the late French philosopher and historian as a galvanizing thinker whose career as a theorist and activist will continue to serve as a model for other gay intellectuals, activists, and scholars. A close reading of both Foucault and the increasing attacks on his life and work, it explains why straight liberals so often find in Foucault only counsels of despair on the subject of politics, whereas gay activists look to him not only for intellectual inspiration but also for a compelling example of political resistance. Halperin rescues Foucault from the endless nature-versus-nurture debate over the origins of homosexuality ("On this question I have absolutely nothing to say," Foucault himself once remarked) and argues that Foucault's decision to treat sexuality not as a biological or psychological drive but as an effect of discourse, as the product of modern systems of knowledge and power, represents a crucial political breakthrough for lesbians and gay men. Halperin explains how Foucault's radical vision of homosexuality as a strategic opportunity for self-transformation anticipated the new anti-assimilationist, anti-essentialist brand of sexual identity politics practiced by contemporary direct-action groups such as ACT UP. Halperin also offers the first synthetic account of Foucault's thinking about gay sex and the future of the lesbian and gay movement, as well as an up-to-the-minute summary of the most recent work in queer theory. "Where there is power, there is resistance," Michel Foucault wrote in The History of Sexuality, Volume I. Erudite, biting, and surprisingly moving, Saint Foucault represents Halperin's own resistance to what he views as the blatant and systematic misrepresentation of a crucial intellectual figure, a misrepresentation he sees as dramatic evidence of the continuing personal, professional, and scholarly vulnerability of all gay activists and intellectuals in the age of AIDS.

Confronted with the apparent explanatory gap between physical processes and consciousness, there are many possible reactions. Some deny that any explanatory gap exists at all. Some hold that there is an explanatory gap for now, but that it will eventually be closed. Some hold that the explanatory gap corresponds to an ontological gap in nature.

In this innovative study, Lea David critically investigates the relationship between human rights and memory, suggesting that, instead of understanding human rights in a normative fashion, human rights should be treated as an ideology. Conceptualizing human rights as an ideology gives us useful theoretical and methodological tools to recognize the real impact human rights has on the ground. David traces the rise of the global phenomenon that is the human rights memorialization agenda, termed 'Moral Remembrance', and explores what (...) happens once this agenda becomes implemented. Based on evidence from the Western Balkans and Israel/Palestine, she argues that the human rights memorialization agenda does not lead to a better appreciation of human rights but, contrary to what would be expected, it merely serves to strengthen national sentiments, divisions and animosities along ethnic lines, and leads to the new forms of societal inequalities that are closely connected to different forms of corruptions.

Liberal thinkers of the eighteenth and nineteenth centuries were alert to the political costs and human cruelties involved in European colonialism, but they also thought that European expansion held out progressive possibilities. In Progress, Pluralism, and Politics David Williams examines the colonial and anti-colonial arguments of Adam Smith, Immanuel Kant, Jeremy Bentham, and L.T. Hobhouse. Williams locates their ambivalent attitude towards European conquest and colonial rule in a set of tensions between the impact of colonialism on European states, the (...) possibilities of progress in distant and diverse places, and the relationship between universalism and cultural pluralism. In so doing he reveals some of the central ambiguities that characterize the ways that liberal thought has dealt with the reality of an illiberal world. Of particular importance are appeals to various forms of universal history, attempts to mediate between the claims of identity and the reality of difference, and the different ways of thinking about the achievement of liberal goods in other places. Pointing to key elements in still ongoing debates within liberal states about how they should relate to illiberal places, Progress, Pluralism, and Politics enriches the discussion on political thought and the relationship between liberalism and colonialism.

As a continuation of the work of the third author in [5], we make further observations on the features of Galois cohomology in the general model theoretic context. We make explicit the connection between forms of definable groups and first cohomology sets with coefficients in a suitable automorphism group. We then use a method of twisting cohomology (inspired by Serre’s algebraic twisting) to describe arbitrary fibres in cohomology sequences—yielding a useful “finiteness” result on cohomology sets. Applied to the special case (...) of differential fields and Kolchin’s constrained cohomology, we complete results from [3] by proving that the first constrained cohomology set of a differential algebraic group over a bounded, differentially large, field is countable.
