Recent evidence in natural and semi-natural settings has revealed a variety of left-right perceptual asymmetries among vertebrates. These include preferential use of the left or right visual hemifield during activities such as searching for food, agonistic responses, or escape from predators in animals as different as fish, amphibians, reptiles, birds, and mammals. There are obvious disadvantages in showing such directional asymmetries because relevant stimuli may be located to the animal's left or right at random; there is no a priori association (...) between the meaning of a stimulus (e.g., its being a predator or a food item) and its being located to the animal's left or right. Moreover, other organisms (e.g., predators) could exploit the predictability of behavior that arises from population-level lateral biases. It might be argued that lateralization of function enhances cognitive capacity and efficiency of the brain, thus counteracting the ecological disadvantages of lateral biases in behavior. However, such an increase in brain efficiency could be obtained by each individual being lateralized without any need to align the direction of the asymmetry in the majority of the individuals of the population. Here we argue that the alignment of the direction of behavioral asymmetries at the population level arises as an “evolutionarily stable strategy” under “social” pressures occurring when individually asymmetrical organisms must coordinate their behavior with the behavior of other asymmetrical organisms of the same or different species. Key Words: asymmetry; brain evolution; brain lateralization; development; hemispheric specialization; laterality; lateralization of behavior; social behavior; theory of games. (shrink)

The hypothesis that nonhuman species, lacking verbal language, do not really integrate information from different modules, but use instead information sequentially, appears difficult to put under empirical scrutiny. Evidence is discussed showing that in nonhuman species storing of geometric information occurs spontaneously even when landmark information suffices for spatial reorientation, suggesting simultaneous encoding, if not use, of information from different modules.

The present response elaborates and defends the main theses advanced in the target article: namely, that in order to provide an evolutionary account of brain lateralization, we should consider advantages and disadvantages associated both with the individual possession of an asymmetrical brain and with the alignment of the direction of lateralization at the population level. We explain why we believe that the hypothesis that directional lateralization evolved as an evolutionarily stable strategy may provide a better account than alternative hypotheses. We (...) also further our discussion of the influence of stimulation and experience in early life on lateralization, and thereby show that our hypothesis is not deterministic. We also consider some novel data and ideas in support of our main thesis. (shrink)

The stratification in depth of chromatically homogeneous overlapping figures depends on a minimization rule which assigns the status of being “in front” to the figure that requires the formation of shorter modal contours. This rule has been proven valid also in birds, whose visual neuroanatomy is radically different from that of other mammals, thus suggesting an example of evolutionary convergence toward a perceptual universal. [Shepard].

It is argued that the alleged cases of cognitive penetration of visual modules actually arise from the integration of information among different modules. This would reflect a general computational strategy according to which constraints to a particular module would be provided by information coming from different modules. Examples are provided from the integration of stereopsis and occlusion and from computation of motion direction.

Some of the foundations of Heyes’ radical reasoning seem to be based on a fractional selection of available evidence. Using an ethological perspective, we argue against Heyes’ rapid dismissal of innate cognitive instincts. Heyes’ use of fMRI studies of literacy to claim that culture assembles pieces of mental technology seems an example of incorrect reverse inferences and overlap theories pervasive in cognitive neuroscience.

The ability to represent, discriminate, and perform arithmetic operations on discrete quantities (numerosities) has been documented in a variety of species of different taxonomic groups, both vertebrates and invertebrates. We do not know, however, to what extent similarity in behavioral data corresponds to basic similarity in underlying neural mechanisms. Here, we review evidence for magnitude representation, both discrete (countable) and continuous, following the sensory input path from primary sensory systems to associative pallial territories in the vertebrate brains. We also speculate (...) on possible underlying mechanisms in invertebrate brains and on the role played by modeling with artificial neural networks. This may provide a general overview on the nervous system involvement in approximating quantity in different animal species, and a general theoretical framework to future comparative studies on the neurobiology of number cognition.

Honeybees show lateral asymmetry in both learning about odours associated with reward and recalling memory of these associations. We have extended this research to show that bees exhibit lateral biases in their initial response to odours: viz., turning towards the source of an odour presented on their right side and turning away from it when presented on their left side. The odours we presented were the main component of the alarm pheromone, iso-amyl acetate (IAA), and four floral scents. The significant (...) bias to turn towards IAA odour on the right and away from it on the left is, we argue, a lateralization of the fight-flight response elicited by this pheromone. It contrasts to an absence of any asymmetry in the turning response to an odour of the flowers on which the bees had been feeding prior to testing: to this odour they turned towards when it was presented on either the left or right side. Lemon and orange odours were responded to differently on the left and right sides (towards on the right, away on the left) but no asymmetry was found in responses to rose odour. Our results show that side biases are present even in the initial, orienting response of bees to certain odours. (shrink)

Núñez and Fias raised concerns on whether our results demonstrate a linear number-space mapping. Patro and Nuerk urge caution on the use of animal models to understand the origin of the orientation of spatial–numerical association. Here, we discuss why both objections are unfounded.

In this paper we review the literature on social learning mechanisms in the domestic chick, focusing largely on work from our own laboratories. The domestic chicken is a social-living bird that searches for food in flocks, avoids predators by following warnings from other flock members, and forms (stable) social hierarchies. All of these behaviors develop throughout ontogeny, largely during the very early stages post-hatch. Newly hatched chicks appear to have predispositions to orient towards and to pay greatest attention to the (...) biologically relevant characteristics of their immediate environment (i.e. to conspecifics: the mother bird and/or fellow hatchlings) from which they may subsequently learn. In addition, the chick has a lateralized brain; left and right hemispheres being specialized for certain behavioral functions and responses, and it appears that such behavioral lateralization is also transposed onto certain social learning situations, which will also be considered. Keywords: social learning; social cognition; chick; brain asymmetry. (shrink)

In this book, one of Italy's most important and original contemporary philosophers considers the status of art in the modern era. He takes seriously Hegel's claim that art has exhausted its spiritual vocation. He argues, however, that Hegel by no means proclaimed the 'death of art' (as many still imagine) but proclaimed rather the indefinite continuation of art in a 'self-annulling' mode. With astonishing breadth and originality, he probes the meaning, aesthetics, and historical consequences of that self-annulment. He argues that (...) the birth of modern aesthetics is the result of a series of schisms - such as between artist and spectator, genius and taste, and form and matter - that are manifestations of the deeper, self-negating yet self-perpetuating movement of irony. He offers an imaginative reinterpretation of the history of aesthetic theory from Kant to Heidegger. The final chapter offers a dazzling interpretation of Dürer's Melancholia. (shrink)

The work of Giorgio Agamben, one of Italy's most important and original philosophers, has been based on an uncommon erudition in classical traditions of philosophy and rhetoric, the grammarians of late antiquity, Christian theology, and modern philosophy. Recently, Agamben has begun to direct his thinking to the constitution of the social and to some concrete, ethico-political conclusions concerning the state of society today, and the place of the individual within it. In Homo Sacer, Agamben aims to connect the problem (...) of pure possibility, potentiality, and power with the problem of political and social ethics in a context where the latter has lost its previous religious, metaphysical, and cultural grounding. Taking his cue from Foucault's fragmentary analysis of biopolitics, Agamben probes with great breadth, intensity, and acuteness the covert or implicit presence of an idea of biopolitics in the history of traditional political theory. He argues that from the earliest treatises of political theory, notably in Aristotle's notion of man as a political animal, and throughout the history of Western thinking about sovereignty, a notion of sovereignty as power over "life" is implicit. The reason it remains merely implicit has to do, according to Agamben, with the way the sacred, or the idea of sacrality, becomes indissociable from the idea of sovereignty. Drawing upon Carl Schmitt's idea of the sovereign's status as the exception to the rules he safeguards, and on anthropological research that reveals the close interlinking of the sacred and the taboo, Agamben defines the sacred person as one who can be killed and yet not sacrificed—a paradox he sees as operative in the status of the modern individual living in a system that exerts control over the collective "naked life" of all individuals.

Why has power in the West assumed the form of an "economy," that is, of a government of men and things? If power is essentially government, why does it need glory, that is, the ceremonial and liturgical apparatus that has always accompanied it? In the early centuries of the Church, in order to reconcile monotheism with God's threefold nature, the doctrine of Trinity was introduced in the guise of an economy of divine life. It was as if the Trinity amounted (...) to nothing more than a problem of managing and governing the heavenly house and the world. Agamben shows that, when combined with the idea of providence, this theological-economic paradigm unexpectedly lies at the origin of many of the most important categories of modern politics, from the democratic theory of the division of powers to the strategic doctrine of collateral damage, from the invisible hand of Smith's liberalism to ideas of order and security. But the greatest novelty to emerge from _The Kingdom and the Glory _ is that modern power is not only government but also glory, and that the ceremonial, liturgical, and acclamatory aspects that we have regarded as vestiges of the past actually constitute the basis of Western power. Through a fascinating analysis of liturgical acclamations and ceremonial symbols of power—the throne, the crown, purple cloth, the Fasces, and more—Agamben develops an original genealogy that illuminates the startling function of consent and of the media in modern democracies. With this book, the work begun with _Homo Sacer_ reaches a decisive point, profoundly challenging and renewing our vision of politics. (shrink)

The end of human history is an event that has been foreseen or announced by both messianics and dialecticians. But who is the protagonist of that history that is coming—or has come—to a close? What is man? How did he come on the scene? And how has he maintained his privileged place as the master of, or first among, the animals? In The Open, contemporary Italian philosopher Giorgio Agamben considers the ways in which the “human” has been thought of (...) as either a distinct and superior type of animal, or a kind of being that is essentially different from animal altogether. In an argument that ranges from ancient Greek, Christian, and Jewish texts to twentieth-century thinkers such as Heidegger, Benjamin, and Kojève, Agamben examines the ways in which the distinction between man and animal has been manufactured by the logical presuppositions of Western thought, and he investigates the profound implications that the man/animal distinction has had for disciplines as seemingly disparate as philosophy, law, anthropology, medicine, and politics.

In this highly topical book, Agamben ultimately arrives at original ideas about the future of democracy and casts a new light on the hidden relationship that ties law to violence.

L'eclissi della politica è cominciata da quando essa ha omesso di confrontarsi con le trasformazioni che ne hanno svuotato categorie e concetti. Accade così che paradigmi genuinamente politici vadano ora cercati in esperienze e fenomeni che di solito non sono considerati politici: la vita naturale degli uomini restituita al centro della polis; il campo di concentramento; il rifugiato; il linguaggio come luogo politico per eccellenza, oggetto di una contesa e di una manipolazione senza precedenti; la sfera dei mezzi puri o (...) dei gesti, ossia dei mezzi che, pur restando tali, si emancipano dalla loro relazione a un fine. Il libro cerca di ripensare le categorie della politica in una nuova realtà. (shrink)

Giorgio Agamben's Homo Sacer was one of the seminal works of political philosophy in recent decades. It was also the beginning of a series of interconnected investigations of staggering ambition and scope, investigating the deepest foundations of Western politics and thought. The Use of Bodies represents the ninth and final volume in this twenty-year undertaking, breaking considerable new ground while clarifying the stakes and implications of the project as a whole. It comprises three major sections. The first uses Aristotle's (...) discussion of slavery as a starting point for radically rethinking notions of selfhood; the second calls for a complete reworking of Western ontology; and the third explores the enigmatic concept of "form-of-life," which is in many ways the motivating force behind the entire Homo Sacer project. Interwoven between these major sections are shorter reflections on individual thinkers, while the epilogue pushes toward a new approach to political life that breaks with the destructive deadlocks of Western thought. The Use of Bodies represents a true masterwork by one of our greatest living philosophers. (shrink)

This volume constitutes the largest collection of writings by the Italian philosopher Giorgio Agamben hitherto published in any language and all but one appear in English for the first time. The essays consider figures in the history of philosophy (Plato, Plotinus, Spinoza, Hegel) and twentieth-century thought (Walter Benjamin, Heidegger, Derrida, Deleuze, the historian Aby Warburg, and the linguist J.-C. Milner). They also examine several central concerns of Agamben: the relation of linguistic and metaphysical categories; messianism in Islamic, Jewish, and (...) Christian theology; and the state and future of contemporary politics. Despite the diversity of the texts collected here, they show a consistent concern for a set of overriding philosophical themes concerning language, history, and potentiality. (shrink)

We can no longer speak of a state of war in any traditional sense, yet there is currently no viable theory to account for the manifold internal conflicts, or civil wars, that increasingly afflict the world's populations. Meant as a first step toward such a theory, Giorgio Agamben's latest book looks at how civil war was conceived of at two crucial moments in the history of Western thought: in ancient Athens (from which the political concept of stasis emerges) and (...) later, in the work of Thomas Hobbes. It identifies civil war as the fundamental threshold of politicization in the West, an apparatus that over the course of history has alternately allowed for the de-politicization of citizenship and the mobilization of the unpolitical. The arguments herein, first conceived of in the immediate aftermath of 9/11, have become ever more relevant now that we have entered the age of planetary civil war. (shrink)

What is an apparatus? -- The friend -- What is the contemporary?

In this follow-up to The Kingdom and the Glory and The Highest Poverty, Agamben investigates the roots of our moral concept of duty in the theory and practice of Christian liturgy. Beginning with the New Testament and working through to late scholasticism and modern papal encyclicals, Agamben traces the Church's attempts to repeat Christ's unrepeatable sacrifice. Crucial here is the paradoxical figure of the priest, who becomes more and more a pure instrument of God's power, so that his own motives (...) and character are entirely indifferent as long as he carries out his priestly duties. In modernity, Agamben argues, the Christian priest has become the model ethical subject. We see this above all in Kantian ethics. Contrasting the Christian and modern ontology of duty with the classical ontology of being, Agamben contends that Western philosophy has unfolded in the tension between the two. This latest installment in the study of Western political structures begun in Homo Sacer is a contribution to the study of liturgy, an extension of Nietzsche's genealogy of morals, and a reworking of Heidegger's history of Being.

Why do we use epistemic modals like 'might'? According to Factualism, the function of 'might' is to exchange information about state-of-affairs in the modal universe. As an alternative to Factualism, this paper offers a game-theoretic rationale for epistemic possibility operators in a Bayesian setting. The background picture is one whereby communication facilitates coordination, but coordination could fail if there's too much uncertainty, since the players' ability to share a belief is undermined. However, 'might' and related expressions can be used to (...) reveal one's uncertainty, and exploit this to coordinate despite the lack of a common epistemic ground. The final result is a way to articulate a non-Factualist view of epistemic possibility modals that builds on their standard semantics. (shrink)

In this book the Italian philosopher Giorgio Agamben looks closely at the literature of the survivors of Auschwitz, probing the philosophical and ethical questions raised by their testimony."In its form, this book is a kind of perpetual commentary on testimony. It did not seem possible to proceed otherwise. At a certain point, it became clear that testimony contained at its core an essential lacuna; in other words, the survivors bore witness to something it is impossible to bear witness to. (...) As a consequence, commenting on survivors' testimony necessarily meant interrogating this lacuna or, more precisely, attempting to listen to it. Listening to something absent did not prove fruitless work for this author. Above all, it made it necessary to clear away almost all the doctrines that, since Auschwitz, have been advanced in the name of ethics."--Giorgio Agamben. (shrink)

The debate around the notions of a priori knowledge and a posteriori knowledge has proven crucial for the development of many fields in philosophy, such as metaphysics, epistemology, metametaphysics etc. We advocate that the recent debate on the two notions is also fruitful for man-made distributed computing systems and for the epistemic analysis thereof. Following a recently proposed modal and fallibilistic account of a priori knowledge, we elaborate the corresponding concept of a priori belief: We propose a rich taxonomy of (...) types of a priori beliefs and their role for the different agents that participate in the system engineering process, which match the existing view exceedingly well and are particularly promising for explaining and dealing with unexpected behaviors in fault-tolerant distributed systems. Developing such a philosophical foundation will provide a sound basis for eventually implementing our ideas in a suitable epistemic reasoning and analysis framework and, hence, constitutes a mandatory first step for developing methods and tools to cope with the various challenges that emerge in such systems.
