When Gilles Deleuze, in his book on Michel Foucault, asks, ‘who would think of looking for life among the archives?’, he uncovers something particular to Foucault's philosophy, but also to his own: a commitment to the question of what it means to think, and think politically. Although Foucault and Deleuze, who first met in 1952, immediately felt fondness for each other, a growing animosity had settled into the friendship by the end of the 1970s – a rift deepened by theoretical (...) differences. Notwithstanding these difficulties, Foucault and Deleuze shared a love for Nietzsche, as well as a curious fascination with Kant. Kant's influence, which was met with more opposition, is precisely the tension I tease out in this article, showing how Foucault critiques Kant's a priori through his own concept of the historical a priori, along with regularity and resistance, while Deleuze and Guattari, if more obliquely, critique Kant's a priori by further developing Foucault's notion of the historical a priori through their own method of pragmatics, particularly in three chapters of A Thousand Plateaus, namely ‘The Geology of Morals’, ‘Postulates of Linguistics’ and ‘On Several Regimes of Signs’. What I am interested in, then, is Deleuze and Guattari's treatment of redundancy, a concept mentioned seventy times in A Thousand Plateaus. Although not one of their main or most developed concepts, redundancy is a thread that can be traced back to Deleuze's first book, Empiricism and Subjectivity. Moreover, their more developed concepts, for example the diagram, the abstract machine, becoming, micro-politics and the ritornello, as well as their political philosophy, are grounded in their understanding of redundancy, which moves their philosophy beyond mapping out the conditions of possibility and demonstrating that the historical a priori emerges as a contingent function of its own expression to the genesis of thought.

Biogenic approaches investigate cognition from the standpoint of evolutionary function, asking what cognition does for a living system and then looking for common principles and exhibitions of cognitive strategies in a vast array of living systems—non-neural to neural. One worry which arises for the biogenic approach is that it is overly permissive in terms of what it construes as cognition. In this paper I critically engage with a recent instance of this way of criticising biogenic approaches in order to clarify (...) their theoretical commitments and prospects. In his critique of the biogenic approach, Fred Adams uses the presence of intentional states with conceptual content as a criterion to demarcate cognition-driven behaviour from mere sensory response. In this paper I agree with Adams that intentionality is the mark of the cognitive, but simultaneously reject his overly restrictive conception of intentionality. I argue that understanding intentionality simpliciter as the mark of the mental is compatible with endorsing the biogenic approach. I argue that because cognitive science is not exclusively interested in behaviour driven by intentional states with the kind of content Adams demands, the biogenic approach’s status as an approach to cognition is not called into question. I then go on to propose a novel view of intentionality whereby it is seen to exist along a continuum which increases in the degree of representational complexity: how far into the future representational content can be directed and drive anticipatory behaviour. Understanding intentionality as existing along a continuum allows biogenic approaches and anthropogenic approaches to investigate the same overarching capacity of cognition as expressed in its different forms positioned along the continuum of intentionality. Even if all organisms engage in some behaviour that is driven by weak intentional dynamics, this does not suggest that every behaviour of all organisms is so driven. As such, the worry that the biogenic approach is overly permissive can be avoided. (shrink)

The notion of a physiological individuals has been developed and applied in the philosophy of biology to understand symbiosis, an understanding of which is key to theorising about the major transition in evolution from multi-organismality to multi-cellularity. The paper begins by asking what such symbiotic individuals can help to reveal about a possible transition in the evolution of cognition. Such a transition marks the movement from cooperating individual biological cognizers to a functionally integrated cognizing unit. Somewhere along the way, did (...) such cognizing units simultaneously have cognizers as parts? Expanding upon the multiscale integration view of the Free Energy Principle, this paper develops an account of reciprocal integration, demonstrating how some coupled biological cognizing systems, when certain constraints are met, can result in a cognizing unit that is in ways greater than the sum of its cognizing parts. Symbiosis between V. Fischeri bacteria and the bobtail squid is used to provide an illustration this account. A novel manner of conceptualizing biological cognizers as gradient is then suggested. Lastly it is argued that the reason why the notion of ontologically nested cognizers may be unintuitive stems from the fact that our folk-psychology notion of what a cognizer is has been deeply influenced by our folk-biological manner of understanding biological individuals as units of reproduction.

Under the assumption that anticipatory models are required for anticipatory behavior, an important question arises about the different manners in which organisms acquire anticipatory models. This article aims to articulate four different non-exhaustive ways that anticipatory models might possibly be acquired over both phylogenetic and ontogenetic timescales and explore the relationships among them. To articulate these different model-acquisition mechanisms, four schematics will be introduced, each of which represents a particular acquisition structure that can be used for the purposes of comparison, (...) analysis, and hypothesis formulation. By bringing to the fore the differences and similarities between each of the four ways that anticipatory models are acquired, a more complete picture of both anticipatory behavior and its pervasive role in biological self-maintenance can be offered. In doing so, this article helps not only to shed light on how anticipatory behavior might arise in the wide range of organisms that it has been observed in but also to throw into relief the subtle and often still overlooked causal interplay between ontogenetic and phylogenetic plasticity.

Basal cognition investigates cognition working upward from nonneuronal organisms. Because basal cognition is committed to empirically testable hypotheses, a methodological challenge arises: how can experiments avoid using zoocentric assumptions that ignore the ecological contexts that might elicit cognitively driven behavior in nonneuronal organisms? To meet this challenge, I articulate the principle of dynamic holism (PDH), a methodological principle for guiding research on nonneuronal cognition. I describe PDH’s relation to holistic research programs in human-focused cognitive science and psychology then present an (...) argument from analogy based on holistic developmental biology. Last, I examine two experiments exemplifying the need for PDH. (shrink)

Action-based theories of cognition place primary emphasis upon the role that agent-environment coupling plays in the emergence of psychological states. Prima facie, mental imagery seems to present a problem for some of these theories because it is understood to be stimulus-absent and thus thought to be decoupled from the environment. However, mental imagery is much more multifaceted than this “naïve” view suggests. Focusing on a particular kind of imagery, comparative mental imagery generation, this paper demonstrates that although such imagery is (...) stimulus-absent, it is also stimulus-sensitive. Exhibiting stimulus-sensitivity is sufficient for a process to qualify as coupled to the environment. The notion of variant coupling is explicated as the coupling of a cognizer’s perceptual system to variant environmental information. By demarcating the categories of stimulus-absent and stimulus-sensitive cognition, and variant and invariant coupling, this paper expands the conceptual apparatus of action-based theories, suggesting not only a way to address the problem that comparative mental imagery generation presents, but perhaps a way to account for other forms of imagery too.

Intelligence in current AI research is measured according to designer-assigned tasks that lack any relevance for an agent itself. As such, tasks and their evaluation reveal a lot more about our intelligence than the possible intelligence of agents that we design and evaluate. As a possible first step in remedying this, this article introduces the notion of “self-concern,” a property of a complex system that describes its tendency to bring about states that are compatible with its continued self-maintenance. Self-concern, as (...) argued, is the foundation of the kind of basic intelligence found across all biological systems, because it reflects any such system's existential task of continued viability. This article aims to cautiously progress a few steps closer to a better understanding of some necessary organisational conditions that are central to self-concern in biological systems. By emulating these conditions in embodied AI, perhaps something like genuine self-concern can be implemented in machines, bringing AI one step closer to its original goal of emulating human-like intelligence.

We are pleased to feature a video interview with Jonathan Sim, where he shares his ongoing journey of integrating artificial intelligence (AI) in his teaching, the challenges encountered along the way, and what educators can do to get their students to meaningfully engage with AI tools like ChatGPT to enhance their learning.

Predictive processing theories are increasingly popular in philosophy of mind; such process theories often gain support from the Free Energy Principle (FEP)—a nor- mative principle for adaptive self-organized systems. Yet there is a current and much discussed debate about conflicting philosophical interpretations of FEP, e.g., repre- sentational versus non-representational. Here we argue that these different interpre- tations depend on implicit assumptions about what qualifies (or fails to qualify) as representational. We deploy the Free Energy Principle (FEP) instrumentally to dis- tinguish (...) four main notions of representation, which focus on organizational, struc- tural, content-related and functional aspects, respectively. The various ways that these different aspects matter in arriving at representational or non-representational interpretations of the Free Energy Principle are discussed. We also discuss how the Free Energy Principle may be seen as a unified view where terms that tradition- ally belong to different ontologies—e.g., notions of model and expectation versus notions of autopoiesis and synchronization—can be harmonized. However, rather than attempting to settle the representationalist versus non-representationalist debate and reveal something about what representations are simpliciter, this paper demon- strates how the Free Energy Principle may be used to reveal something about those partaking in the debate; namely, what our hidden assumptions about what represen- tations are—assumptions that act as sometimes antithetical starting points in this persistent philosophical debate.

When I ask students how they feel about group projects, the response is often negative. This is usually a result of bad experiences with problematic group members, such as free riders who do not contribute or members who bulldoze their ideas through while disregarding their peers. After many semesters mediating disputes within such groups, I have found that issues often stem from concerns about “saving face”. This leads to a lack of much-needed communication. In this article, I offer three methods (...) to facilitate effective group work by improving participation and communication between student peers. (shrink)

The drive for human connection and to discover one’s identity is not limited to the online world: It is a universal human need that we all share. It is crucial to understand that problems we typically attribute to gaming platforms (like self-radicalisation) are not special tech problems or gaming problems. They can and do happen offline as well. What we are dealing with is essentially a human problem that so happens to occur on technological platforms.

Trust is the foundation for learning, and we must not allow ignorance of this new technologies, like Generative AI, to disrupt the relationship between students and educators. As a first step, we need to actively engage with AI tools to better understand how they can help us in our work.

The recent news of a 13-year-old Singaporean prodigy graduating from an Australian university has sparked discussion about Singapore’s approach to nurturing exceptional young talents, especially after it was revealed that the boy had been previously rejected by a local university because of his young age. Some have called for an increased flexibility to allow such young people to skip levels in Singapore - parents of intellectually advanced children often cite concerns that their children are disengaged and bored at school. The (...) fear is real - keeping these students at the same level as their peers could potentially squander their potential and impede their growth. Yet, on the flip side, accelerating their academic journey could potentially jeopardise their social and emotional development, which could negatively impact their ability to connect and work well with their peers in their adulthood. Nonetheless, this debate brings to light the need for more effective strategies to meaningfully engage students with diverse abilities and learning paces. (shrink)

Humans have long wondered whether they can survive the death of their physical bodies. Some people now look to technology as a means by which this might occur, using terms such 'whole brain emulation', 'mind uploading', and 'substrate independent minds' to describe a set of hypothetical procedures for transferring or emulating the functioning of a human mind on a synthetic substrate. There has been much debate about the philosophical implications of such procedures for personal survival. Most participants to that debate (...) assume that the continuation of identity is an objective fact that can be revealed by scientific enquiry or rational debate. We bring into this debate a perspective that has so far been neglected: that personal identities are in large part social constructs. Consequently, to enable a particular identity to survive the transference process, it is not sufficient to settle age-old philosophical questions about the nature of identity. It is also necessary to maintain certain networks of interaction between the synthetic person and its social environment, and sustain a collective belief in the persistence of identity. We defend this position by using the example of the Dalai Lama in Tibetan Buddhist tradition and identify technological procedures that could increase the credibility of personal continuity between biological and artificial substrates.

Jonathan takes us through his experiences of being a mentor for UTOP (University Teaching Opportunities Programme), particularly how it enabled him to collaborate with his UTOP student mentees to design a learning activity in which students could think critically about AI-generated output.

In my discussion with students, I found that many of them have high levels of anxiety when it comes to learning something outside their intended major. In this article, I explain how I supported my class remotely using the Telegram messaging app to keep a regular flow of communication and reassure students they were not alone in having queries.

The flipped-classroom format is a type of blended learning where students are required to do preparatory work – such as watching lecture videos or completing assignments – before coming to a face-to-face class to work on more challenging problems with the facilitation of an instructor. However, one challenge of teaching flipped-classroom modules is that a big proportion of students often come to class unprepared. Either they do not watch the lecture videos or they skim through them before the tutorials. Thus, (...) they lack a proper understanding of the content and many are unable to participate in class activities. The tutorial ends up becoming a lecture where we go over the basic content instead of challenging the students to take their learning further. In this article, I explain explains how I designed learning activities to ensure students complete the preparation work necessary to get the most out of the flipped-classroom model. (shrink)

Assignment feedback is key to helping students improve and correct their understanding so they can build upon solid foundations of knowledge as their course progresses. Yet, I found that about 30% of students review their feedback. It is not because students are lazy but because they struggle to find the time and often have little immediate incentive to review feedback for something that has already been graded when they have other assignments to work on. Feedback is most effective when it (...) is shared with students while they are still working on the assignment. In this article, I share how regular quizzes as a tool to ensure students review their assignment feedback and address gaps in their understanding. (shrink)

A problematic trend I notice when conversing with students is how many of them struggle to remember what they did in modules from previous semesters. These discussions got me thinking about how to design learning activities that are unforgettable. Albert Einstein, among other figures credited with the quote, famously said that “education is what remains after one has forgotten what one has learned in school”. I want to ensure my students remember what they have learned from me, especially after all (...) the hard work they put into the course. In this article, I share teaching techniques designed to pique the emotions as a way to lodge key lessons more firmly in students’ memories. (shrink)

As a teacher in Singapore, I regularly encounter a classroom full of quiet students, reluctant to participate in class, to engage with the teacher when questioned, or even to volunteer for any project or initiative. Many teachers here are quick to conclude that Singapore students are passive or conformists. This observation is, in fact, not unique to students in Singapore, but also to the broader Asian region. Scholars like Cortazzi and Jin (1996) attributed such behaviour to the specific cultural values, (...) such as the importance of deference to the authority of a teacher, as reasons for such passivity and reticence. Liu and Littlewood (1997), on the other hand, argue that people from certain cultures prefer not to speak up so as to avoid entering into situations of uncertainty. I have found that as a teacher busily pre-occupied with preparing for classes, it is easy to forget how students perceive their learning experience, and I have been quite inclined to agree with the observations above. Fortunately, I have had the opportunity to be both a post-graduate student and a teacher. And this privileged position allows me to question some of my own assumptions as a teacher, thereby gaining deeper insights into the underlying reasons for the lack of participation here in Singapore. There is a lot more going on in the minds of Singapore students. Here, I would like to offer a new perspective on this matter. (shrink)

The contribution of Jacques Maritain to twentieth century political philosophy has been widely noted. This paper explores the implications of Maritain’s work and life for contemporary spirituality, in particular, for a spirituality that might nourish and shape democratic participation. It finds the roots of such a spirituality in Maritain’s integral vision of the person, and his view of saints as those persons who alone have fully resolved the human condition. Maritain argues that while sanctity so defined is universal, it must (...) be adapted to the changing conditions of history. Contemporary democracy, in particular, has expanded the possibilities of the human being’s temporal task, and so calls for new styles of sanctity to embrace the new range of human activity. This paper explores the characteristics of sanctity in a democracy, according to Maritain. It finds that the defining features of such sanctity are solidarity, embodied in suffering and fraternal love, and contemplation diversely expressed through both prayer and action. Finally it explores the implications of Maritain’s spirituality for contemporary Catholic citizens. (shrink)

Jonathan discusses the learning issues he observed which prompted him to adopt this platform in his teaching, the implementation process, and his observations of his students’ response to this approach.

Teaching interdisciplinary modules online can be an uphill battle but it offers important lessons in the art of motivating students to learn.

Humanities and social science majors are frequently misunderstood, in Singapore as in many other parts of the world. The value of their education is regularly questioned, and many employers are unaware of the value such majors can bring to the table. They prefer to hire graduates with more explicitly “practical” degrees for jobs that humanities and social sciences students could excel in. As a result, humanities and social sciences students are not typically considered for many organisations and roles, despite offering (...) relevant and useful skills. In this article, I describe how I engaged with local employers to open internship opportunities to humanities and social sciences students who would not previously have been considered. (shrink)

The late Clark Kerr, one of the great leaders and thinkers of American higher education in the 20th century, shaped the landscape of higher education in the United States, starting with California, where he lived and worked. When he was the President of the University of California (UC) (1958–1967), he formulated and led the implementation of the California Master Plan of Higher Education (California State Department of Education, 1960) in response to an urgent need for higher education reforms in the (...) 1960s. The Plan aimed at providing universal access to higher education and diversity in the choices of institutions available to all Californians. This was achieved by defining the methods for allocating funding and missions to colleges and universities. He moved on to head the Carnegie Commission on Higher Education (1967–1973) and the Carnegie Council on Policy Studies in Higher Education (1973–1979). There, he was fundamental in developing sophisticated new tools and concepts for the study of higher education policy, which made a great impact on higher education and education policy in the United States and beyond.

Context — Children and adults with psychopathic traits and conduct or oppositional defiant disorder demonstrate poor decision making and are impaired in reversal learning. However, the neural basis of this impairment has not previously been investigated. Furthermore, despite high comorbidity of psychopathic traits and attention deficit/hyperactivity disorder, to our knowledge, no research has attempted to distinguish neural correlates of childhood psychopathic traits and attention-deficit/hyperactivity disorder. Objective—To determine the neural regions that underlie the reversal learning impairments in children with psychopathic traits (...) plus conduct or oppositional defiant disorder. Design — Case-control study. Setting — Government clinical research institute. Participants — Forty-two adolescents aged 10 to 17 years: 14 with psychopathic traits and oppositional defiant disorder or conduct disorder, 14 with attention-deficit/hyperactivity disorder only, and 14 healthy controls. Main Outcome Measure — Blood oxygenation level–dependent signal as measured via functional magnetic resonance imaging during a probabilistic reversal task. Results — Children with psychopathic traits showed abnormal responses within the ventromedial prefrontal cortex (Brodmann area 10) during punished reversal errors compared with children wit hattention deficit/hyperactivity disorder and healthy children (P < .05 corrected for multiple comparisons). Conclusions — To our knowledge, this study provides the first evidence of abnormal ventromedial prefrontal cortex responsiveness in children with psychopathic traits and demonstrates this dysfunction was not attributable to comorbid attention-deficit/hyperactivity disorder. These findings suggest that reversal learning impairments in patients with developmental psychopathic traits relate to abnormal processing of reinforcement information. (shrink)

It might become possible to build artificial minds with the capacity for experience. This raises a plethora of ethical issues, explored, among others, in the context of whole brain emulations (WBE). In this paper, I will take up the problem of vulnerability – given, for various reasons, less attention in the literature – that the conscious emulations will likely exhibit. Specifically, I will examine the role that vulnerability plays in generating ethical issues that may arise when dealing with WBEs. I (...) will argue that concerns about vulnerability are more matters of institutional design than individual ethics, both when it comes to creating humanlike brain emulations, and when animal-like emulations are concerned. Consequently, the article contains reflection on some institutional measures that can be taken to protect the sims' interests. It concludes that an institutional framework more likely to succeed in this task is competitive and poly-centric, rather than monopolistic and centralized. (shrink)

Nick Bostrom argues that if we accept some plausible assumptions about how the future will unfold, we should believe we are probably not humans. The argument appeals crucially to an indifference principle whose precise content is a little unclear. I set out four possible interpretations of the principle, none of which can be used to support Bostrom’s argument. On the first two interpretations the principle is false, on the third it does not entail the conclusion, and on the fourth it (...) only entails the conclusion given an auxiliary hypothesis that we have no reason to believe.

This study focused on creating an Audio-Visual Strategic Intervention Material (SIM) to help Grade 7 students improve their skills in performing fundamental operations on integers in Mathematics. The research used an Educational Design Research approach and selected participants through purposive sampling. Data collection involved a checklist and rating scale, and analysis was carried out using frequency and mean. The findings revealed that mastering fundamental operations on integers had consistently been the most challenging skill for Grade 7 students during the first (...) quarter over the past three academic years. The SIM underwent a thorough validation process done by expert validators, including Mathematics teachers and content specialists, who assessed its content, instructional design, and technical quality. The experts provided a mean rating of 3.63, indicating that the material was of very high quality. The high validation scores affirmed that the Audio-Visual SIM met high standards in terms of content accuracy, instructional effectiveness, and technical presentation. The study highlights the potential of audio-visual materials as an effective tool for addressing learning gaps in Mathematics, providing educators with a valuable resource to improve students' foundational skills in integer operations. The findings also guided the planning of extension activities, and recommendations for further refinement and broader use of the SIM were provided. To continue assisting students in overcoming these challenges, the Institution, through its extension program, may offer workshops, seminars, and training sessions on the creation and use of Audio-Visual SIMs. (shrink)

I have developed transcendental arguments to refute several versions of Nick Bostrom’s simulation hypothesis. I called some of these arguments the SIM-style argument. In this paper, I have four main aims. First, I employ the SIM-style argument to remedy a defect in Hilary Putnam’s Brain-in-vat argument. Second, I show that the most radical skepticism, which Tim Button called the nightmarish Cartesian skepticism, can be refuted by the SIM-style argument or by another transcendental argument I develop here. Third, I compare my (...) approach to radical skepticisms with Donald Davidson’s, as it is often regarded as an exemplar of transcendental arguments. Fourth, I explain how the prominent objections, mainly developed by Barry Stroud, to transcendental arguments can incur two undesirable results: psychologism and Kantian skepticism. (shrink)

The SIMS model claims that it is by means of an embodied simulation that we determine the meaning of an observed smile. This suggests that crucial interpretative work is done in the mapping that takes us from a perceived smile to the activation of one's own facial musculature. How is this mapping achieved? Might it depend upon a prior interpretation arrived at on the basis of perceptual and contextual information?

This article uses sim-max games to model perceptual categorization with the goal of answering the following question: To what degree should we expect the perceptual categories of biological actors to track properties of the world around them? I argue that an analysis of these games suggests that the relationship between real-world structure and evolved perceptual categories is mediated by successful action in the sense that organisms evolve to categorize together states of nature for which similar actions lead to similar results. (...) This conclusion indicates that both strongly realist and strongly antirealist views about perceptual categories are too simple. (shrink)

‘‘Theoretical biology’’ is a surprisingly heter- ogeneous field, partly because it encompasses ‘‘doing the- ory’’ across disciplines as diverse as molecular biology, systematics, ecology, and evolutionary biology. Moreover, it is done in a stunning variety of different ways, using anything from formal analytical models to computer sim- ulations, from graphic representations to verbal arguments. In this essay I survey a number of aspects of what it means to do theoretical biology, and how they compare with the allegedly much more restricted (...) sense of theory in the physical sciences. I also tackle a recent trend toward the presentation of all-encompassing theories in the biological sciences, from general theories of ecology to a recent attempt to provide a conceptual framework for the entire set of biological disciplines. Finally, I discuss the roles played by philosophers of science in criticizing and shap- ing biological theorizing. (shrink)

A filosofia da linguagem dedica-se ao estudo da linguagem natural. Não se dedica ao estudo de línguas particulares, tal como o português, o castelhano ou o inglês, mas sim ao estudo filosófico de características gerais da linguagem e da nossa capacidade e proficiência linguística enquanto seres humanos. A investigação do desenvolvimento da linguagem é uma tarefa a ser desenvolvida pela ciência – a paleontologia, a neurologia, etc. Mas a ciência ocupa-se de algo de que temos um conhecimento intuitivo prévio – (...) a linguagem natural. Ora, a filosofia da linguagem dedica-se em parte a tornar explícito o nosso conhecimento implícito da linguagem. Como tal, a filosofia da linguagem é uma disciplina central na filosofia. Este capítulo é uma introdução selectiva à filosofia da linguagem. A alternativa que se nos deparava era fazer uma breve apresentação de teorias do significado, da referência e da verdade, e ainda de alguns tópicos de pragmática, ou escolher um tópico em particular que é, tradicionalmente, o elegido nos cursos introdutórios à filosofia da linguagem. Este capítulo oferece assim uma introdução a alguns dos temas centrais e clássicos da filosofia da linguagem contemporânea. A maior parte do capítulo dedicar-se-á a teorias da referência, a de Frege e de Russell, e à sua crítica subsequente por filósofos como Saul Kripke. Isto poderia levar-nos a pensar que a filosofia da linguagem contemporânea continua, como era tradicional, focada simplificada da relação entre linguagem, mente e mundo. Nada podia estar mais longe da verdade, como se tornará claro. A grande alteração na perspectiva sobre o estudo da linguagem, que se deve a pessoas como Frege ou Russell, é que graças ao seu trabalho os filósofos passaram a reflectir sobre a contribuição semântica sistematicamente feita por diferentes categorias sintácticas nas diferentes construções frásicas em que possam ocorrer, por exemplo a de termos referenciais como os nomes próprios. A relação linguagem-mente-mundo continua a ser uma preocupação dos filósofos contemporâneos, mas de uma forma muito mais sofisticada, rigorosa e sistemática. Os filósofos preocupam-se agora, por exemplo, com as condições de verdade correctas de usos particulares de frases, com os estados de coisas reais ou possíveis que confeririam verdade ou falsidade às frases usadas, e com o valor cognitivo de distintos tipos de frases. Como indicaremos na última secção do capítulo, outros desenvolvimentos da filosofia da linguagem contemporânea dizem respeito àquilo que nós, enquanto seres humanos, conseguimos fazer por meio da linguagem, aos diferentes actos de fala possíveis, e aos diferentes níveis de significado que podemos comunicar por meio do uso de frases com um significado convencionalmente estabelecido.

O problema deste paper constitui-se a partir da seguinte pergunta: seria Platão um plagiador dos pitagóricos? A suspeita nasce de uma tradição já antiga pela qual Platão é acusado de ter plagiado uma suposta obra atualmente perdida de Filolau de Crotona. Tomou-se, então, como objeto de análise, a obra Timeu, a fim de verificar a existência de trechos que poderiam sugerir um plágio por parte de Platão. Para tanto, realizou-se um levantamento das principais teorias “pitagóricas” identificáveis no Timeu, a partir (...) de uma revisão da história da crítica. Concluiu-se que, inegavelmente, há referência implícita ao pitagorismo na obra, a qual, entretanto, não configura propriamente um plágio, mas, sim, pode ser melhor considerada como uma influência pitagórica. Efetivamente, Platão acaba por transpor diversas teorias “pitagóricas” – bem como de outros filósofos pré-socráticos – para seus próprios interesses filosóficos. (shrink)

The central claim of normative pragmatism is that intentional states can be explained in terms of participation in practices. My aim in this paper is not so much to defend this claim as to rearticulate it in a different medium: the medium of computation. I describe two computer programs in which this claim is re-expressed. The first is the latest version of THE SIMS, in which participation in practices enables the Sims to do and understand more. The second (...) is a prototype simulation of philosophical debate. In this second program, normative pragmatism is expressed at two different levels: once as the theory powering the implementation, and once as a set of claims which are debated by the simulated philosophers. Here, a philosophical theory is used to implement a system in which that very same theory is articulated, challenged, and justified. (shrink)

Sheep production is the most representative livestock activities in Brazil and in the world. However, the reproductive performance of these animals is determined by factors genetic, physical environment, management and, especially, nutritional. Thirty half-breed lambs from Dorper × Santa Inês were used, with initial weight and age of 31.87 ± 0.5 kg and 157 days, respectively. These animals were prepared on a diet with three food levels (ad libitum, 30% and 70%). Morphometric measurements were measured at intervals of 16 to (...) 20 days in 56 experimental days. The measurements performed were scrotal circumference (CE), chest circumference (CT), body condition score (ECC), withers height (AC) and scrotal bag thickness (EBE), body weight (CP) and semen collection. Interaction occurrence for biometric measurements between food levels and age (p <0.05). The TC and ECC values were higher in animals fed ad libitum (p <0.001). EBE had higher values in animals ad libitum and at 211 days of age (p <0.001). The CP was increasing for the animals ad libitum and (p <0.05) throughout the experiment, while the T30 was only in the initial period. T70 animals did not grow during the whole experiment. CE was influenced by diet (p <0.001) and age (p <0.001) independently. So that animals under food restriction had less development and was higher in older animals. The AC values were influenced only by age (p <0.001), demonstrating the effect of age growth. We conclude that it is not advantageous to submit lambs, it corrects food reproduction. Although it was not possible to assess whether initial malnutrition would bring future problems for the animal's seminal quality, it proved to be immensely negative for the onset of puberty and the development of reproductive structures. -/- REFERÊNCIAS BIBLIOGRÁFICAS AKUMBUGU, F.

A mais de um século que o fenômeno da automatização dos meios de trabalho vem criando grande apreensão entre nós. Afinal, seríamos todos substituídos por máquinas em algum futuro próximo? Seriam todas as formas de trabalho automatizáveis? Tais questionamentos vêm levantando uma série de críticas pela comunidade engajada em ética de máquina e ética da inteligência artificial. Contudo, gostaria de nesta breve resenha, atacar este problema por outro ângulo, afinal, podemos criticar tal fenômeno de uma ampla variedade de pontos de (...) vista. Gostaria de convidar o leitor a avaliar pela seguinte perspectiva: e se a automação dos meios de trabalho for algo benéfico? E se a emancipação humana realmente venha através de nosso desenvolvimento tecnológico? Se a resposta for sim, por quê quê ainda trabalhamos tanto? Acredito que se os processos de automação forem aplicados a pontos chave de nossa estrutura social, podemos vir a emancipar o indivíduo de uma realidade onde realmente trabalhamos por motivo nenhum, inutilmente. Se abandonarmos a cultura do consumismo, a cultura que atrela o trabalho e o consumo a moralidade, uma alternativa mais próspera seria adotarmos a cultura que abraça o valor da autonomia e liberdade do indivíduo humano.

Resumo: O texto reconstrói as bases teleológico-morais para a constituição da moderna ciência da história. A chave dessa reconstrução é o escrutínio da idéia kantiana de plano da natureza, idéia que é investigada nas obras de Adam Smith, Hegel e Marx. Para criticar essa idéia, argui-se o pensamento de Fukuyama e defende-se que a ligação entre democracia e economia liberal é melhor explicada pela natural inclinação humana para a simetria do que pela noção de reconhecimento. O argumento é que o (...) projeto de Fukuyama não encontra amparo na seleção da espécie, ao passo que o desejo por simetria sim. A essa abordagem subjazem as teses de que feita a crítica à teleologia moral, a história tem de ser compatível com a evolução, e de que a naturalização da história implica numa naturalização da moral.Palavras-chave: teleologia - moral naturalizada - plano da natureza - teoria da história - evolucionismo.: The text reconstructs the teleological-moral foundations for the constitution of the modern science of history. The key to that reconstruction is a scrutiny of Kant's idea of "plan of nature", which is investigated in the works of Adam Smith, Hegel and Marx. In order to criticize this idea, the paper discusses the thinking of Fukuyama and argues that the connection between democracy and liberal economy is best explained by the natural human inclination towards symmetry, rather than by the notion of recognition. It also argues that Fukuyama's project finds no support in the selection of species, whereas the desire for symmetry does. The theses that underlie this approach are that, once the critique of moral teleology has been made, history must be compatible with evolution and that the naturalization of history implies a naturalization of morals.

Se propone un examen crítico de la última obra de J.-L. Marion titulada, dedicada a la unión de alma y cuerpo, y cuya tesis principal es: los problemas que esta unión suscita confunden dos términos, cuerpo y mi cuerpo. Esta confusión lleva a que se apliquen al primero categorías propias del segundo. Se examinan las "paradojas ónticas" que mi cuerpo (la carne) inaugura (a); se despeja la tesis de dos interpretaciones de las meditaciones primera y sexta (b); se discute la (...) "excepción a la metafísica" instaurada por el conocimiento de mi cuerpo (c); se arriesga, siguiendo una indicación del autor, la apertura a una dimensión ética que exige examinar ya no la unión de cuerpo y alma, sino la unión por el amor a un semejante y a la comunidad de semejantes (d). -/- The article carries out a critical examination of J.-L. Marion's latest work, "Sur la pensée passive de Descartes", whose main thesis is that the problems posed by the union of body and soul confuse two terms: body and my body. This confusion leads to the application to the former of categories inherent to the latter. The paper examines the "ontic paradoxes" that my body (the flesh) gives rise to (a); it clarifies the thesis of two interpretations of the First and Sixth Meditations (b); it discusses the "exception to metaphysics" established by the knowledge of my body (c); and, following an indication by the author, it proposes an opening to the ethical dimension, which demands an examination of the union, through love, with a fellow human being and with the community of human beings, rather than of the union of body and soul (d). -/- Neste artigo, propõe-se um exame crítico da última obra de J.-L. Marion, intitulada "Sur la pensée passive de Descartes", dedicada à união de alma e corpo, e cuja tese principal é: os problemas que essa união suscita confundem dois termos, corpo e meu corpo. Essa confusão leva a que se apliquem ao primeiro categorias próprias do segundo. Examinam-se os "paradoxos ônticos" que meu corpo (a carne) inaugura; a tese de duas interpretações das medita ccedil;ões primeira e sexta é esclarecida; arrisca-se, seguindo uma indicação do autor, a abertura a uma dimensão ética que exige examinar já não a união de corpo e alma, mas sim a união pelo amor a um semelhante e à comunidade de semelhantes.

This paper compares two approaches to representing personality traits in synthetic agents. It proposes a set of goals that any computational implementation of personality should satisfy. It describes the personality trait system used in The Sims 3. Then an alternative system is described, in which traits are represented as conditionals relating world state to emotional state. It is shown that the conditionals model does a better job of satisfying the desiderata.

DOENÇAS E HIGIENE -/- -/- Emanuel Isaque Cordeiro da Silva Departamento de Zootecnia da UFRPE E-mail: [email protected] WhatsApp: (82)98143-8399 -/- -/- AS DOENÇAS -/- O organismo animal está continuamente sujeito a tensões e agressões provenientes do meio que o cerca. Porém, o complexo conjunto de órgãos que formam qualquer ser vivo e que funcionam continuamente mediante complicadas reações químicas, possui meios de defesa muito eficazes. Se o agente prejudicial atua por pouco tempo ou a agressão é pouco expressiva, o corpo (...) atacado põe em funcionamento mecanismos reguladores e defensivos automáticos, e tudo volta a funcionar fisiologicamente, ou seja, normalmente. Isto está sempre a acontecer sem que percebamos. -/- Mas se o agente é muito prejudicial ou atua durante muito tempo sobre o animal acaba-se alterando o organismo do mesmo, se produzem lesões e aparecem os sintomas da doença. Algumas vezes a parte alterada é uma pequena área da pele ou das mucosas internas, ou apenas afeta ligeiramente um órgão, e então a doença é leve e cura fácil. -/- Porém, em alguns casos, as lesões afetam um órgão importante ou a muitos, e como todas as funções do organismo estão relacionadas entre si, acabam alterando os demais e a doença torna-se grave e até mortal. -/- CLASSES DE DOENÇAS -/- A Patologia é a ciência médica que se encarrega do estudo das doenças que podem ser muito variadas. Muitas delas poderiam ser evitadas, mas para isso, é necessário conhecê-las ou pelo menos ter uma ideia de como elas se originam e afetam o sistema humano e/ou animal. -/- Buscando uma simplificação, e tendo em conta as causas e o modo de como as doenças se apresentam, agruparei as doenças em quatro esferas: congênitas, parasitárias, infecciosas e esporádicas. Observe a figura abaixo e, posteriormente, ao texto que segue. -/- Figura 1: Classes de doenças. -/- Doenças congênitas -/- São aquelas que se herdam dos pais. Após a união das células sexuais (espermatozoides e óvulo) dos progenitores, os genes que vão nos cromossomos são passados para os filho e assim são transmitidas as características que lhes corresponde mediante as leis da herança. Às vezes, essas características são indesejáveis, isto é, que podem causar a morte da cria ou fazer com que seu corpo apresente anormalidades (bezerros com cabeça de Bulldog, por exemplo). -/- Na espécie humana, é bem conhecida o caso de hemofilia, doença hereditária que ocasiona hemorragias perigosas pelo simples fato do impedimento da coagulação do sangue nas feridas. -/- -/- Em muitas ocasiões, o que se herda não são doenças concretas, mas sim a predisposição a padecer delas. -/- Não obstante, nunca devemos confundir as doenças congênitas com as que a mãe pode transmitir ao feito durante a gestação ou no momento do parto. -/- Doenças infecciosas -/- São causadas por micróbios tão pequenos, que só podem ser vistos com um microscópio. Muitos deles são contagiosos e causam febre. Os germes patogênicos que causam doenças, reproduzem-se rapidamente depois de terem conseguido entrar no corpo da vítima, e são geralmente bactérias (como as que produzem tuberculose ou brucelose) ou vírus (por exemplo, os causadores da febre aftosa ou da raiva). Também podem ser fungos microscópicos. -/- Doenças parasitárias -/- São as produzidas por seres que vivem sobre o corpo do animal ou em seu interior, vivendo a sua costa, debilitando-o e causando-lhe danos. Quase sempre se trata de pequenos animais, que em um determinado momento de sua vida invadem o organismo do hospedeiro; uns ficam na pele e se denominam parasitas externos (como os carrapatos, pulgas ou os ácaros da sarna) mas outros penetram nas cavidades internas e tecidos, denominando-se então parasitas internos (por exemplo, os vermes estrôngilos do pulmão, a triquina dos músculos ou a solitária do intestino). -/- Doenças esporádicas -/- São aquelas que afetam, ocasionalmente, os animais isolados e cuja causa não é nenhuma das mencionadas nas outras três classes de doenças. Neste grupo incluímos, portanto, qualquer doença que não seja congênita, parasitária ou infecciosa. Podem ser produzidas pelas mais variadas intempéries, por exemplo: - agentes físicos (congelamento, queimaduras, acidentes...); - mal alimentação (diarreias, anemia, intoxicações por plantas...); - transtornos hormonais (agressividade, esterilidade...) e - reprodução descontrolada das células (tumores benignos, câncer...). -/- HIGIENE -/- É o conjunto de procedimentos que procuram evitar que o organismo adoeça. Trata-se de prevenir as doenças, de evitar, por qualquer meio, que venham a ocorrer. Dependendo do tipo de doença, as medidas de higiene recomendadas para a evitá-las serão diferentes. As congênitas poderiam ser evitadas mediante a identificação das características genéticas dos animais reprodutores e a prevenção do cruzamento dos que são capazes de transmitir genes indesejáveis. A invasão de parasitas pode ser evitada através da administração de determinadas substâncias químicas ou através da remoção dos seus ovos e larvas das pastagens e locais onde quer que se encontrem. As doenças infecciosas podem ser evitadas mediante a adoção de medidas sanitárias destinadas a prevenir o contágio, vacinar os animais ou matar os germes com desinfetantes. Até várias doenças podem desaparecer com medidas higiênicas adequadas, assim como se evita a anemia ferropriva dos leitões administrando-lhes ferro. -/- Os conhecimentos em matéria de higiene são tão importantes que, se fossem postos em prática, a maior parte das doenças poderia ser evitada. Muitos agricultores poupariam muito do dinheiro que gastam em medicamentos e do dinheiro que perdem quando os seus animais morrem, se soubessem alguma prática higiênica, profiláticas ou medidas preventivas. E com isso melhoraria também sua própria saúde. -/- Por fim vale lembrar que: a LIMPEZA evita a sujeira, mas a HIGIENE evita as doenças. -/- Respeite os direitos autorais.

Most formalisms for representing common-sense knowledge allow incomplete and potentially inconsistent information. When strong negation is also allowed, contradictory conclusions can arise. A criterion for deciding between them is needed. The aim of this paper is to investigate an inherent and autonomous comparison criterion, based on specificity as defined in [POO 85, SIM 92]. In contrast to other approaches, we consider not only defeasible, but also strict knowledge. Our criterion is context-sensitive, i. e., preference among defeasible rules is determined dynamically (...) during the dialectical analysis.We show how specificity can be defined in terms of two different approaches: activation sets and derivation trees. This allows us to get a syntactic criterion that can be implemented in a computationally attractive way. The resulting definitions may be applied in general rulebased formalisms. We present theorems linking both characterizations. Finally we discuss other frameworks for defeasible reasoning in which preference handling is considered explicitly. (shrink)

Embora não o desenvolva na exposição que se segue, o argumento subjacente à minha contribuição para este volume é bastante simples: há duas vias pelas quais a filosofia de Nietzsche pode contribuir positivamente para uma revisão do modo como os seres humanos no ocidente definiram sua relação com o não humano: (1) a primeira via é a agonística – a tese agonística pode ser mobilizada para combater o viés especista que caracteriza boa parte da reflexão normativa do ocidente sem que (...) isso nos comprometa com a suposição de que é possível abandonar o perspectivismo em sua versão forte (a tese segundo a qual nossos esquemas conceituais e perceptuais, ou o fato de pertencermos a uma mesma história natural, nos aprisionam na perspectiva da espécie humana). O agonismo é uma posição filosófica que recusa a supremacia absoluta de uma formação de domínio como um arranjo prejudicial à própria formação de domínio; (2) a segunda via é a da filosofia da afirmação incondicional do acaso ou da necessidade, como Nietzsche se expressa alternativamente. Esta via comporta uma dimensão religiosa, por mais chocante que isso possa parecer a ouvidos nietzschianos. Nesta perspectiva da afirmação incondicional, todas as forças atuantes são igualmente afirmadas e a perspectiva normativa preservada minimamente na abordagem agonística é como que suprimida e toda tensão dissolvida. Segundo minha interpretação, a filosofia afirmativa defendida por Nietzsche exige uma política da reconciliação que vai além da perspectiva agonística. Ela representa a superação da visão moral de mundo na sua forma mais drástica: com um dizer sim até mesmo à perspectiva do último homem. Mas é justamente aí que as coisas começam a assumir ares dramáticos, pois Nietzsche reconhece que esta perspectiva não pode ser facilmente aceita em suas diversas implicações. Embora as duas vias que acabamos de mencionar possam inspirar legitimamente o projeto de uma revisão do antropocentrismo que caracterizou a reflexão normativa no ocidente, é necessário reconhecer que alguns traços do pensamento nietzschiano tornam esta tarefa de revisão altamente improvável. Uma vez assumida, a segunda via exigiria, por exemplo, a supressão de um dos traços centrais da personalidade filosófica de Nietzsche. Refiro-me a seu incansável ativismo em prol da autossuperação dos tipos mais elevados da humanidade. Esta dificuldade revela uma das facetas mais importantes da filosofia de Nietzsche, que consiste em seu compromisso com uma forma depurada de humanismo; um compromisso radical, que não pode ser ignorado por seus leitores. Esta forma depurada de humanismo fornece a autorização teórica para o lado sombrio da utopia nietzschiana: seu flerte com a noção de uma história planificada e de uma administração global da terra, como forma de promover o cultivo dos homens de exceção. Este lado sombrio da utopia nietzschiana pode ser descrito como um desdobramento consequencialista de sua ética perfeccionista, e está na origem das derivações políticas que o filósofo alemão extrai deste compromisso ético. Penso que isso justifique a expressão hiperbólica utilizada no título de minha contribuição: “A catástrofe do humanismo”. Sempre que esta modalidade de humanismo depurado prevalece na reflexão de Nietzsche, a única voz perceptível nesta que é a mais polifônica das escritas filosóficas é a voz do ativista militando em prol dos homens de exceção. Quando esse tipo de engajamento prevalece, não é possível discernir nenhuma contribuição especificamente nietzschiana ao tema em torno do qual nos propusemos a refletir nesta coletânea: nestas ocasiões Nietzsche permanece indubitavelmente no interior de uma tradição que confere exclusividade ao humano em sua reflexão normativa.

O presente trabalho tem por objetivo fornecer uma resposta à crítica direcionada pelo jurista Fábio Konder Comparato ao formalismo jurídico de Kant. Explicarei porque essa crítica se equivoca quando identifica, na Doutrina do Direito de Kant, uma Teoria do Direito incompleta e insatisfatória. Para tanto, pretendo mostrar que o propósito do filósofo alemão não era apresentar uma teoria do direito, mas sim uma Metafísica do Direito. O que explica, por conseguinte, a razão para o direito ter sido concebido como um (...) conceito puro. Além disso, a fim de determinar o significado do formalismo jurídico, ocupar-me-ei da crítica hegeliana ao suposto formalismo ético de Kant, bem como da resposta a essa crítica. (shrink)

No debate acerca da singularidade de, pelos menos, alguns de nossos pensamentos sobre o mundo, assume-se corriqueiramente que o responsável pela natureza singular do episódio mental não é o próprio episódio e, sim, a proposição singular expressa quer por um proferimento assertórico de sentença singular autônoma, quer pela cláusula complementar em um relato de atribuição de atitude proposicional. As rotas semânticas padrão assumem que a singularidade do episódio mental (conceitual) é por assim dizer “herdada” da singularidade do conteúdo. Argumento que (...) este pressuposto apresenta uma lacuna, pois desconsidera o papel desempenhado em certos atos de pensamento, chamados de episódicos, por habilidades cognitivas tais como a capacidade de perceber objetos particulares, de vivenciar (novamente) ou de projetar-se mentalmente em direção a acontecimentos particulares pessoais, diretamente responsáveis por sua singularidade. No entanto, contra a tese de que haveria capacidades episódicas aí envolvidas, argumento que a singularidade dos atos de pensar episódicos se dá pelo exercício pontual no espaço e no tempo dessas capacidades e há, portanto, um sentido não derivado em que eles podem ser qualificados como singulares.

Não é novidade no ambiente acadêmico as reticências da teórica crítica Nancy Fraser para com a teoria da justiça de John Rawls. Mais especificamente, sua desconfiança é que a justiça rawlsiana não seja capaz de capturar devidamente a complexidade das desigualdades sociais nas sociedades contemporâneas: seja porque sua teoria moral (da justiça) é presumidamente descolada de uma teoria social de fundo; seja porque sua teoria moral (da justiça) é considerada reducionista (ou “monista”). Porém, o espírito do presente artigo não é (...) de aprofundar suas diferenças metodológicas, mas sim colocar as bases para se pensar possíveis “semelhanças de família” entre suas concepções de justiça. Afinal, ambas as formulações se apresentam como abordagens “deontológicas”, ou seja, que priorizam o correto (o justo) sobre o bem. Na primeira seção, retorna-se ao célebre debate redistribuição e reconhecimento, onde Fraser apresenta as novas abordagens liberais – com destaque à de Rawls - como as principais representantes do paradigma redistributivo no cenário contemporâneo. Ao mergulhar nessas passagens, é possível revelar precisamente quais os pontos de concordância e discordância de Fraser para com a teoria deontológica de Rawls. Dando continuidade, na segunda seção é explorado sua principal discordância: o presumido “reducionismo” da teoria da justiça rawlsiana à dimensão redistributiva (econômica), aqui chamada de crítica do reducionismo redistributivo. Se essa objeção procede ou não é objeto da terceira e última seção. Nela, é argumentado que mesmo que as preocupações normativas de Fraser (quanto ao problema do reducionismo) sejam válidas, ainda assim, esse problema não se aplica à teoria rawlsiana. Ao contrário, é argumentado que é possível encontrar “semelhanças de família” entre as concepções de Fraser e Rawls: (a) no seu alicerce e compromisso com o pluralismo, (b) na sua investigação e defesa do status igualitário entre as pessoas e, finalmente, (c) na constatação que o ideal normativo da igualdade democrática entre as pessoas (ou paridade de participação) requer dos arranjos institucionais não somente a redistribuição de recursos e bens econômicos, como também elementos de qualidades diferentes.

O objetivo do presente texto é o de apresentar as bases do atomismo metafísico a partir da produção do conhecimento na Antiguidade Clássica. Não se trata de abrir qualquer tipo de discussão acerca da produção do conhecimento contemporâneo sobre a realidade do átomo. Trata-se de apresentar os fundamentos teóricos de base grega, cujos reflexos foram sentidos nos desenvolvimentos posteriores do atomismo metafísico. Sendo assim, a pretensão não é a de apresentar um trabalho específico de História da Filosofia ou de História (...) da Ciência, mas sim, de um estudo da Filosofia da Ciência no contexto de sua história; pois, diante da questão sobre qual seria a competência epistêmica que delimita a Filosofia em sua essência, não encontramos outra maneira de tentar determiná-la a não ser consultando sua própria história.

For Machiavelli, religion is valued not by the importance of its founder, the content of its teachings, the truth of its dogmas or the significance of its rites. It is not the essence of what really matters but its function and importance for collective life. Religion teaches to recognize and respect political rules through the religious commandments. This collective norm could assume the outer coercive aspect of the military discipline as well as the inner persuasive character of civic and moral (...) education for the production of collective consensus. -/- Para Maquiavel, o que confere valor a uma religião não é a importância de seu fundador, o conteúdo dos ensinamentos, a verdade dos dogmas ou a significação dos mistérios e ritos. Importa não a essência da religião e sim sua função e importância para a vida coletiva. A religião ensina a reconhecer e a respeitar as regras políticas a partir do mandamento religioso. Essa norma coletiva pode assumir tanto o aspecto coercivo exterior da disciplina militar ou da autoridade política quanto o caráter persuasivo interior da educação moral e cívica para a produção do consenso coletivo.
