In a reflective and richly entertaining piece from 1979, Doug Hofstadter playfully imagined a conversation between ‘Achilles’ and an anthill (the eponymous ‘Aunt Hillary’), in which he famously explored many ideas and themes related to cognition and consciousness. For Hofstadter, the anthill is able to carry on a conversation because the ants that compose it play roughly the same role that neurons play in human languaging; unfortunately, Hofstadter’s work is notably short on detail suggesting how this magic might be achieved1. (...) Conversely in this paper - finally reifying Hofstadter’s imagination - we demonstrate how populations of simple ant-like creatures can be organised to solve complex problems; problems that involve the use of forward planning and strategy. Specifically we will demonstrate that populations of such creatures can be configured to play a strategically strong - though tactically weak - game of HeX (a complex strategic game).We subsequently demonstrate how tactical play can be improved by introducing a form of forward planning instantiated via multiple populations of agents; a technique that can be compared to the dynamics of interacting populations of social insects via the concept of meta-population. In this way although, pace Hofstadter, we do not establish that a meta-population of ants could actually hold a conversation with Achilles, we do successfully introduce Aunt Hillary to the complex, seductive charms of HeX.

Upshot: Albeit mostly supportive of our work, the commentaries we received highlighted a few points that deserve additional explanation, with regard to the notion of learning in our model, the relationship between our model and the brain, as well as the notion of anticipation. This open discussion emphasizes the need for toy computer models, to fuel theoretical discussion and prevent business-as-usual from getting in the way of new ideas.

Context: Constructivist approaches to cognition have mostly been descriptive, and now face the challenge of specifying the mechanisms that may support the acquisition of knowledge. Departing from cognitivism, however, requires the development of a new functional framework that will support causal, powerful and goal-directed behavior in the context of the interaction between the organism and the environment. Problem: The properties affecting the computational power of this interaction are, however, unclear, and may include partial information from the environment, exploration, distributed processing (...) and aggregation of information, emergence of knowledge and directedness towards relevant information. Method: We posit that one path towards such a framework may be grounded in these properties, supported by dynamical systems. To assess this hypothesis, we describe computational models inspired from swarm intelligence, which we use as a metaphor to explore the practical implications of the properties highlighted. Results: Our results demonstrate that these properties may serve as the basis for complex operations, yielding the elaboration of knowledge and goal-directed behavior. Implications: This work highlights aspects of interaction that we believe ought to be taken into account when characterizing the possible mechanisms underlying cognition. The scope of the models we describe cannot go beyond that of a metaphor, however, and future work, theoretical and experimental, is required for further insight into the functional role of interaction with the environment for the elaboration of complex behavior. Constructivist content: Inspiration for this work stems from the constructivist impetus to account for knowledge acquisition based on interaction. (shrink)

This paper explores moments of democratising disorderliness that interrupt a vision of the sublime as a particular ordering of subjectivity. Situated within the context of the Narmada movement against the construction of the Sardar Sarovar Dam in India in the mid-1990s, it argues that sublime regimes and ‘counter-sublime’ insurgences draw their energies from the figures of the dam and the bund, respectively. Where the dam’s walls establish the horizons of visibility, of who counts as subject, the bund’s curved surfaces reveal (...) a pluralising depth that folds the visible with/in the invisible, constituting the possibility of novel modes of seeing/subjectification. Working through oral histories, films, images, archival materials and ethnographic studies alongside the work of Foucault and the later Merleau-Ponty, the paper argues that the Narmada movement enacts a counter-sublime that contests the invisibility imposed by the dam in favour of an imbrication of the human and non-human disclosing radically different constellations of visibility and subjectification.

To succeed, we posit that research cartography will require high-throughput natural description to identify unknown unknowns in a particular design space. High-throughput natural description, the systematic collection and annotation of representative corpora of real-world stimuli, faces logistical challenges, but these can be overcome by solutions that are deployed in the later stages of integrative experiment design.

The ArgumentThe paper argues that the distinction between modernism and postmodernism can be applied metaphorically to clarify the changing image of music during the late Middle Ages. The paper discusses the scientific and rational strategies that thirteenth century musical theorists applied to revise earlier musical conceptualization. It highlights the thirteenth-century innovative affiliation of music with Aristotelian physics and argues that in a very subtle and seemingly contradictory way music theorists expressed the nascent awareness, if not tacit acknowledgment, of the mundane (...) nature of music. It argues further that in the fourteenth century the issue of representing musical-rhythmical variability by means of a suitable language shifted to the forefront of musical theory and practice. The unprecedented emphasis on musical signs and their semantic behavior as well as the demand to demystify the discourse about rhythmical concepts — so as to question the necessity of metacategories — all point to an affinity between fourteenth century musical thought and postmodern sensibilities.

In lieu of an abstract, here is a brief excerpt of the content:“Nos faysoms contre Nature...”: Fourteenth-Century Sophismata and the Musical Avant GardeDorit TanayThe secular musical repertory of the late fourteenth century has been described in terms of unparalleled rhythmic intricacies, reflecting a conscious tendency to exhaust the scope of free play within the parameter of time in music. 1 Historians of music see in such musical complexity a case of a musical system in disarray, to be explained by patterns (...) that seem always adequate to account for phases of aberration from stylistic norm, such as the notions of mannerism or fin de siècle phenomenon, understood literally as well as figuratively. 2Current views seem to echo contemporaneous observations. The late fourteenth-century poet-musician Guido cast his critique on what he interprets as a shift towards chaotic musical expression, in a form of an introspective ballade:Or voit tout en aventure Puis qu’ainsi me convient fayre A la novelle figure Qui doyt a chascun desplayre; Que c’est trestout en contraire De bon art qui est parfayt: Certes, ce n’est pas bien fayt. [End Page 29]Nos faysoms contre Nature De ce qu’est bien fayt deffayre; Que Philipe qui mais ne dure Nos dona boin exemplaire. Nos laisons tous ses afayres Por Marquet le contrefayt: Certes, ce n’est pas bien fayt. L’art de Marquet n’a mesureN’onques rien ne sait parfyre; D’ansuir et de portrayre C’est trop grant outrecuidure Ces figures, et tout traire Ou il n’a riens de bon trayt: Certes, ce n’est pas bien fayt. 3Curiously enough, Guido set his ballade to a melody that evokes some of the obscenities deplored in the poem. The musical text displays needless complication, being notated by deceitful figures that are willful, misleading, and difficult to decipher and follow. 4 The literary text, similarly, diversifies words in a vein of irony and ambiguity, clouding any indication as to whether the speaker is for or against the new style. In other words Guido’s esthetic position is sophistic, self-amused, and self-conscious.Since artistic expressions are generally conceived as reflecting their consumers, late-medieval chansons have been interpreted as a manifestation of the incredibly decadent yet sophisticated social milieu in which and for which the music was created. To ground further the argument for the correspondence between the countenance of the music and that of its audience, historians invoke the proximity in time and space between the evolution of the manneristic musical style, significantly in Avignon, and the Great Schism (1378–1417) that [End Page 30] followed the Babylonian Captivity. This famous crisis in the papal reign has been associated with a strong tendency to secularization in the papal Court, by which life styles became luxurious if not licentious. 5This socio-historical account is based on suggestive conjectures, comprising in part explanatory commonplaces. No direct relation can be established between the “Great Schism” or the specific social condition, of Avignon and the most refined music of the late fourteenth century. Furthermore, the claim of the above social account for a contextual approach is misleading. In fact no solid immanent relations are shown to exist between a complex, quasi-degenerate society on the one hand, and the intricate rhythms of the music on the other. The attribution of complexity in the broadest sense of the term does not satisfy our curiosity as to the possible interdependence between style and society. Interestingly enough, as far as late fourteenth-century chansons style is concerned, such an association can even be countered, considering the coincidental cultivation of the new simple style in the complex and decadent Burgundian courts of the waning Middle Ages. 6Here I propose to examine the late fourteenth-century musical style not on the background of social procedures but in the context of fourteenth century scientific thought, and to demonstrate immanent and structural cohesion between a compositional trend that features manipulations within the dimension of musical time and the sciences which investigate the properties of time qua continuum. This affinity concerns a parallel, yet not a completely overlapping, development directed towards the ultimate refinement of the notion of mensura. In other words we are dealing here... (shrink)

Since its birth in 1600 opera has been interpreted as an attempt to revive Greek tragedies in its marvelous music. Its provocative presentation of action and narration entirely in music has been seen as a manifestation of the enchanted universe of sixteenth-century hermeticism. Viewed as a final homage to the magical incantations of the premodern era, late Renaissance operas have been interpreted as the culmination rather than the dissolution of Renaissance culture. This paper proposes that the relationship between the natural (...) and the supernatural in early opera represents a rational mediation between the real and the unreal rather than an enchanted bond between these realms. The paper situates the birth of opera in the context of the epistemological shift of the new science and suggests that opera played a key role in the transition from the old to the modern notions of meaning and truth.

In his Philosophical Inquiry concerning Human Liberty (1717), the English deist Anthony Collins proposed a complete determinist account of the human mind and action, partly inspired by his mentor Locke, but also by elements from Bayle, Leibniz and other Continental sources. It is a determinism which does not neglect the question of the specific status of the mind but rather seeks to provide a causal account of mental activity and volition in particular; it is a ‘volitional determinism’. Some decades later, (...) Diderot articulates a very similar determinism, which seeks to recognize the existence of “causes proper to man” (as he says in the Réfutation d’Helvétius). The difference with Collins is that now biological factors are being taken into account. Obviously both the ‘volitional’ and the ‘biological’ forms of determinism are noteworthy inasmuch as they change our picture of the nature of determinism itself, but my interest here is to compare these two determinist arguments, both of which are broadly Spinozist in nature – and as such belong to what Jonathan Israel called in his recent book “the radical Enlightenment,” i.e. a kind of underground Enlightenment constituted by Spinozism – and to see how Collins’ specifically psychological vision and Diderot’s specifically biological vision correspond to their two separate national contexts: determinism in France in the mid-1750s was a much more medico-biological affair than English determinism, which appears to be on a ‘path’ leading to Mill and associationist psychology.

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)

How do we judge whether an action is morally right or wrong? If an action is wrong, what reason does that give us not to do it? Why should we give such reasons priority over our other concerns and values? In this book, T. M. Scanlon offers new answers to these questions, as they apply to the central part of morality that concerns what we owe to each other. According to his contractualist view, thinking about right and wrong is thinking (...) about what we do in terms that could be justified to others and that they could not reasonably reject. He shows how the special authority of conclusions about right and wrong arises from the value of being related to others in this way, and he shows how familiar moral ideas such as fairness and responsibility can be understood through their role in this process of mutual justification and criticism. Scanlon bases his contractualism on a broader account of reasons, value, and individual well-being that challenges standard views about these crucial notions. He argues that desires do not provide us with reasons, that states of affairs are not the primary bearers of value, and that well-being is not as important for rational decision-making as it is commonly held to be. Scanlon is a pluralist about both moral and non-moral values. He argues that, taking this plurality of values into account, contractualism allows for most of the variability in moral requirements that relativists have claimed, while still accounting for the full force of our judgments of right and wrong.

Synthetic biologists aim to generate biological organisms according to rational design principles. Their work may have many beneficial applications, but it also raises potentially serious ethical concerns. In this article, we consider what attention the discipline demands from bioethicists. We argue that the most important issue for ethicists to examine is the risk that knowledge from synthetic biology will be misused, for example, in biological terrorism or warfare. To adequately address this concern, bioethics will need to broaden its scope, contemplating (...) not just the means by which scientific knowledge is produced, but also what kinds of knowledge should be sought and disseminated.

The integration of normative analysis with empirical data often remains unclear despite the availability of many empirical bioethics methodologies. This paper sought bioethics scholars’ experiences and reflections of doing empirical bioethics research to feed these practical insights into the debate on methods. We interviewed twenty-six participants who revealed their process of integrating the normative and the empirical. From the analysis of the data, we first used the themes to identify the methodological content. That is, we show participants’ use of familiar (...) methods explained as “back-and-forth” methods (reflective equilibrium), followed by dialogical methods where collaboration was seen as a better way of doing integration. Thereafter, we highlight methods that were deemed as inherent integration approaches, where the normative and the empirical were intertwined from the start of the research project. Second, we used the themes to express not only how we interpreted what was said but also how things were said. In this, we describe an air of uncertainty and overall vagueness that surrounded the above methods. We conclude that the indeterminacy of integration methods is a double-edged sword. It allows for flexibility but also risks obscuring a lack of understanding of the theoretical-methodological underpinnings of empirical bioethics research methods. (shrink)

Abstract I argue that the two primary motivations in the literature for positing seemings as sui generis mental states are insufficient to motivate this view. Because of this, epistemological views which attempt to put seemings to work don’t go far enough. It would be better to do the same work by appealing to what makes seeming talk true rather than simply appealing to seeming talk.

Some philosophers have thought that life could only be meaningful if there is no God. For Sartre and Nagel, for example, a God of the traditional classical theistic sort would constrain our powers of self-creative autonomy in ways that would severely detract from the meaning of our lives, possibly even evacuate our lives of all meaning. Some philosophers, by contrast, have thought that life could only be meaningful if there is a God. God and the Meanings of Life is interested (...) in exploring the truth in both these schools of thought, seeking to discover what God could and couldn't do to make life meaningful (as well as what he would and wouldn't do). Mawson espouses a version of the 'amalgam' or 'pluralism' thesis about the issue of life's meaning – in essence, that there are a number of different legitimate meanings of 'meaning' (and indeed 'life') in the question of life's meaning. According to Mawson, God, were he to exist, would help make life meaningful in some of these senses and hinder in some others. He argues that whilst there could be meaning in a Godless universe, there could be other sorts of meaning in a Godly one and that these would be deeper. (shrink)
