We study the influence of the individual behaviour of animals on predator-prey models. Populations of preys and predators are divided into sub-populations corresponding to different activity classes. The animals are assumed to do many activities all day long such as searching for food of different types. The preys are more vulnerable when doing some activities during which they are very exposed to predators attacks rather than for others during which they are hidden. We study activity sequences of the animals and (...) also the effect of a change in the average individual behaviour of the animals on Lotka-Volterra prey-predator interactions. Numerical simulations are realized for the whole sets of equations (governing the subpopulations) and are compared to the simulations of the reduced sets of equation (governing the populations). We look for the validity of the method with respect to a scaling factor which measures the differences between the two time scales associated to the fast-varying variables and to the slow-time varying global variables. It is shown that when the two time scales differ of about two orders of magnitude, the approximation is satisfying. (shrink)

We study the case of two sibling species ofHippolais(Aves). Very little differences can be observed in the morphology of both species. The breeding area of these species are complementary. Roughly, one species breeds North and East of Europe (Hippolais icterina) while the other breeds South and West of Europe (Hippolais polyglotta). There exitst a narrow zone of sympatry passing through Burgundy. Since several years, it has been observed that this area of sympatry was moving in the North-East direction at a (...) European scale. This means that progressivelyH. icterina is declining and is replaced byH. polyglotta. Some assumptions can be made in order to explain this evolution, for instance competition or predation. Series of observations concerning the diets of nestlings of both species have been realized. These observations show some differences in the diet compositions. The breeding success of the two species has been studied. Numerical simulations of a competition model taking into account the observed differences between the food types eaten by the two species are presented. These simulations do not explain the regression ofH. icterina. Then, we present numerical simulations of a predation model with one predator attacking the nestlings of both species. These simulations show that with time one of the two preys must extinct. Predation rather than competition seems to be the right explanation. (shrink)

This paper analyses Giordano Bruno's dialogue De l’infinito universo e mondi, written during his stay in England, in the context of his philosophical works and, particularly, within the context of scientific and imaginative writings such as Cyrano de Bergerac's Other Worlds and Francis Godwin's The Man in the Moone. The article also discusses the contemporary speculations of Galileo and Kepler regarding the existence of a plurality of worlds and the presence of creatures on the moon and their rapport with (...) humans. Besides the imaginative, fantastic and pseudoscientific elements, attention is also given to religious implications and attitudes, especially in the case of Godwin, who, like his countryman John Wilkins—author of The Discovery of the Worlde in the Moone –was a bishop and therefore wanted to avoid any controversy with the church.

Including empirical examples and theoretical clarifications on many of the analytical issues raised in his recently published Down to Earth, this conversation with Bruno Latour and his collaborator, Danish sociologist Nikolaj Schultz, offers key insights into Latour’s recent and ongoing work. Revolving around questions on political ecology and social theory in our ‘New Climatic Regime’, Latour argues that in order to have politics you need a land and you need a people. This interview present reflections on such politics, such (...) land and such people, and it ends with a call for a sociology that takes up the task of connecting the three by investigating what he and Schultz call ‘geo-social classes’. The interview was conducted by Jakob Stein in Paris in November 2018. (shrink)

Revolutionary developments in economics are rare. The conservative bias of the field and its enshrined knowledge make it difficult to introduce new ideas not in line with received theory. Happiness research, however, has the potential to change economics substantially in the future. Its findings, which are gradually being taken into account in standard economics, can be considered revolutionary in three respects: the measurement of experienced utility using psychologists' tools for measuring subjective well-being; new insights into how human beings value goods (...) and services and social conditions that include consideration of such non-material values as autonomy and social relations; and policy consequences of these new insights that suggest different ways for government to affect individual well-being. In Happiness, emphasizing empirical evidence rather than theoretical conjectures, Bruno Frey substantiates these three revolutionary claims for happiness research. After tracing the major developments of happiness research in economics and demonstrating that we have gained important new insights into how income, unemployment, inflation, and income demonstration affect well-being, Frey examines such wide-ranging topics as democracy and federalism, self-employment and volunteer work, marriage, terrorism, and watching television from the new perspective of happiness research. Turning to policy implications, Frey describes how government can provide the conditions for people to achieve well-being, arguing that a crucial role is played by adequate political institutions and decentralized decision making. Happiness demonstrates the achievements of the economic happiness revolution and points the way to future research.Bruno S. Frey is Professor of Economics at the University of Zurich, Visiting Professor at the Swiss Federal Institute of Technology, and Research Director of CREMA. He is co-editor of Economics and Psychology: A Promising New Cross-Disciplinary Field. (shrink)

Placing Bruno—both advanced philosopher and magician burned at the stake—in the Hermetic tradition, Yates's acclaimed study gives an overview not only of Renaissance humanism but of its interplay—and conflict—with magic and occult practices. "Among those who have explored the intellectual world of the sixteenth century no one in England can rival Miss Yates. Wherever she looks, she illuminates. Now she has looked on Bruno. This brilliant book takes time to digest, but it is an intellectual adventure to read (...) it. Historians of ideas, of religion, and of science will study it. Some of them, after reading it, will have to think again.... For Miss Yates has put Bruno, for the first time, in his tradition, and has shown what that tradition was."—Hugh Trevor-Roper, _New Statesman_ "A decisive contribution to the understanding of Giordano Bruno, this book will probably remove a great number of misrepresentations that still plague the tormented figure of the Nolan prophet."—Giorgio de Santillana, _American Historical Review_ "Yates's book is an important addition to our knowledge of Giordano Bruno. But it is even more important, I think, as a step toward understanding the unity of the sixteenth century."—J. Bronowski, _New York Review of Books_. (shrink)

Ontological pluralism is the view that there are different ways to exist. It is a position with deep roots in the history of philosophy, and in which there has been a recent resurgence of interest. In contemporary presentations, it is stated in terms of fundamental languages: as the view that such languages contain more than one quantifier. For example, one ranging over abstract objects, and another over concrete ones. A natural worry, however, is that the languages proposed by the pluralist (...) are mere notational variants of those proposed by the monist, in which case the debate between the two positions would not seem to be substantive. Jason Turner has given an ingenious response to this worry, in terms of a principle that he calls ‘logical realism’. This paper offers a counter-response on behalf of the ‘notationalist’. I argue that, properly applied, the principle of logical realism is no threat to the claim that the languages in question are notational variants. Indeed, there seems to be every reason to think that they are. (shrink)

Prince of Networks is the first treatment of Bruno Latour specifically as a philosopher. It has been eagerly awaited by readers of both Latour and Harman since their public discussion at the London School of Economics in February 2008. Part One covers four key works that display Latour’s underrated contributions to metaphysics: Irreductions, Science in Action, We Have Never Been Modern, and Pandora’s Hope. Harman contends that Latour is one of the central figures of contemporary philosophy, with a highly (...) original ontology centered in four key concepts: actants, irreduction, translation, and alliance. In Part Two, Harman summarizes Latour’s most important philosophical insights, including his status as the first ‘secular occasionalist.’ The problem of translation between entities is no longer solved by the fiat of God (Malebranche) or habit (Hume), but by local mediators. Working from his own ‘object-oriented’ perspective, Harman also criticizes the Latourian focus on the relational character of actors at the expense of their cryptic autonomous reality. This book forms a remarkable interface between Latour’s Actor-Network Theory and the Speculative Realism of Harman and his confederates. It will be of interest to anyone concerned with the emergence of new trends in the humanities following the long postmodernist interval. (shrink)

Bruno Latour was once asked : "Do you believe in reality?" This text is an attempt to answer this question.

Moral Constraints on War offers a principle-by-principle presentation of the transcultural roots of the ethics of war in an age defined by the increasingly international nature of military intervention.

The French, it is well known, love revolutions, political, scientific or philosophical. There is nothing they like more than a radical upheaval of the past, an upheaval so complete that a new tabula rasa is levelled, on which a new history can be built. None of our Prime Ministers starts his mandate without promising to write on a new blank page or to furnish a complete change in values and even, for some, in life. Each researcher would think of him (...) or herself as a failure, if he or she did not make such a complete change in the discipline that nothing will hereafter be the same. As to the philosophers they feed, from Descartes up to Foucault's days, on radical cuts, on ‘coupure épistémologique’, on complete subversion of everything which has been thought in the past by everybody. No French thinker, indeed no student of philosophy, would seriously contemplate doing anything short of a complete revolution in theories. To hesitate, to respect the past, would be to compromise, to be a funk, or worse, to be eclectic like a vulgar Anglo-Saxon! (shrink)

This chapter challenges Cantor’s notion of the ‘power’, or ‘cardinality’, of an infinite set. According to Cantor, two infinite sets have the same cardinality if and only if there is a one-to-one correspondence between them. Cantor showed that there are infinite sets that do not have the same cardinality in this sense. Further, he took this result to show that there are infinite sets of different sizes. This has become the standard understanding of the result. The chapter challenges this, arguing (...) that we have no reason to think there are infinite sets of different sizes. It begins with an initial argument against Cantor’s claim that there are infinite sets of different sizes and then proceeds, by way of an analogy between Cantor’s mathematical result and Russell’s paradox, to a more direct argument.

RESUMEN En el presente trabajo analizo críticamente dos estrategias empleadas para esclarecer la naturaleza modal de las estructuras tal como son concebidas por el realismo estructural óntico en su versión eliminativista: los patrones reales de Ladyman y Ross y las leyes y simetrías de French. Ofrezco argumentos para mostrar que ambas resultan incapaces de brindar una caracterización de las estructuras como entidades inherentemente modales. Ese resultado impone serias dificultades al proyecto de presentar el REO como una posición realista acerca del (...) mundo físico. ABSTACT In this article, I carry out a critical analysis of two strategies employed to clarify the modal nature of structures as conceived by the eliminativist version of Ontic Structural Realism : the real patterns of Ladyman and Ross and French's laws and symmetries. I provide arguments to show that neither of them is capable of coming up with a characterization of structures as inherently modal structures. This result poses serious difficulties for the project of presenting OSR as a realist position regarding the physical world. (shrink)

German classicist's monumental study of the origins of European thought in Greek literature and philosophy. Brilliant, widely influential. Includes "Homer's View of Man," "The Olympian Gods," "The Rise of the Individual in the Early Greek Lyric," "Pindar's Hymn to Zeus," "Myth and Reality in Greek Tragedy," and "Aristophanes and Aesthetic Criticism.".

European thought begins with the Greeks. Scientific and philosophic thinking--the pursuit of truth and the grasping of unchanging principles of life--is a historical development, an achievement; and, as Bruno Snell writes in The Discovery of the Mind, nothing less than a revolution. The Greeks did not take mental resources already at their disposal and merely map out new subjects for discussion and investigation. In poetry, drama, and philosophy they in fact discovered the human mind. The stages in man's gradual (...) understanding of himself are revealed in the course of ancient literature from Homer to Virgil. A rational view of the nature of man slowly established itself in the creations of epic and lyric poetry, tragedy and literary criticism, pre-Socratic thought, and early Greek ethics all the way to the discovery of humanitas and the spiritual landscape of Virgil's Arcadia. The Discovery of the Mind is a landmark work in tracing this evolution of consciousness--one of the distinguishing characteristics of the history of man. (shrink)

Bruno Latour, the French sociologist, anthropologist and long-established superstar in the social sciences is revisited in this pioneering account of his ever-evolving political philosophy. Breaking from the traditional focus on his metaphysics, most recently seen in Harman's book Prince of Networks, the author instead begins with the Hobbesian and even Machiavellian underpinnings of Latour's early period and encountering his shift towards Carl Schmitt and finishing with his final development into the Lippmann / Dewey debate. Harman brings these twists and (...) turns into sharp focus in terms of Latour's personal political thinking. Along with Latour's most important articles on political themes, the book chooses three works as exemplary of the distinct periods in Latour's thinking: The Pasteurization of France, Politics of Nature, and the recently published An Inquiry Into Modes of Existence, as his conception of politics evolves from a global power struggle between individuals, to the fabrication of fragile parliamentary networks, to just one mode of existence among many others.

German classicist's monumental study of the origins of European thought in Greek literature and philosophy.

David Lewis’ Convention has been a major source of inspiration for philosophers and social scientists alike for the analysis of norms. In this essay, I demonstrate its usefulness for the analysis of some moral norms. At the same time, conventionalism with regards to moral norms has attracted sustained criticism. I discuss three major strands of criticism and propose how these can be met. First, I discuss the criticism that Lewis conventions analyze norms in situations with no conflict of interest, whereas (...) most, if not all, moral norms deal with situations with conflicting interests. This criticism can be answered by showing that conventions can emerge in those contexts as well. Secondly, I discuss the objection that this type of conventionalism, inspired by Lewis, presents moral norms as fundamentally contingent, whereas most, if not all, moral norms are not. However, such critics fail to appreciate that conventions are not radically contingent. Moreover, if one distinguishes the question as to why an individual should comply with a norm from the question whether the norm in question itself can be justified, a core element of the complaint of contingency disappears. The third objection to conventionalism concerns the way in which conventionalists justify norms. I argue that reflection upon the way in which according to Lewis norms are justified reveals a fundamental tension in his theory. Possible solutions to this tension all have in common that the complaint of contingency returns in some form. Therefore, this third complaint cannot be avoided altogether. (shrink)

Giordano Bruno's notorious public death in 1600, at the hands of the Inquisition in Rome, marked the transition from Renaissance philosophy to the Scientific Revolution of the seventeenth century. In his philosophical works he addressed such delicate issues as the role of Christ as mediator and the distinction, in human beings, between soul and matter. This volume presents new translations of Cause, Principle and Unity, in which he challenges Aristotelian accounts of causality and spells out the implications of Copernicanism (...) for a new theory of an infinite universe, and of two essays on magic, On Magic and A General Account of Bonding, in which he interprets earlier theories about magical events in the light of the unusual powers of natural phenomena.

Our visual system can process information at both conscious and unconscious levels. Understanding the factors that control whether a stimulus reaches our awareness, and the fate of those stimuli that remain at an unconscious level, are the major challenges of brain science in the new millennium. Since its publication in 1984, Visual Masking has established itself as a classic text in the field of cognitive psychology. In the years since, there have been considerable advances in the cognitive neurosciences, and a (...) growth of interest in the topic of consciousness, and the time is ripe for a new edition of this text. Where most current approaches to the study of visual consciousness adopt a 'steady-state' view, the approach presented in this book explores its dynamic properties. This new edition uses the technique of visual masking to explore temporal aspects of conscious and unconscious processes down to a resolution in the millisecond range. The 'time slices' through conscious and unconscious vision revealed by the visual masking technique can shed light on both normal and abnormal operations in the brain. The main focus of this book is on the microgenesis of visual form and pattern perception - microgenesis referring to the processes occurring in the visual system from the time of stimulus presentation on the retinae to the time, a few hundred milliseconds later, of its registration at conscious or unconscious perceptual and behavioural levels. The book takes a highly integrative approach by presenting microgenesis within a broad context encompassing visuo-temporal phenomena, attention, and consciousness. (shrink)

This book provides a thoroughly worked out and systematic presentation of an interpretivist position in the philosophy of mind, of the view that having mental properties is a matter of interpretation. Bruno Mölder elaborates and defends a particular version of interpretivism, the ascription theory, which explicates the possession of mental states with contents in terms of their canonical ascribability, and shows how it can withstand various philosophical challenges. Apart from a defence of the ascription theory from the objections commonly (...) directed against interpretivism, the book provides a critical analysis of major alternative accounts of mental state possession as well as the interpretivist ideas originating from Donald Davidson and Daniel Dennett. The viability of the approach is demonstrated by showing how one can treat mental causation as well as the faculties closely connected with consciousness -- perception and the awareness of one’s own mental states -- in the interpretivist framework.

Are there ‘self-referential’ propositions? That is, propositions that say of themselves that they have a certain property, such as that of being false. There can seem reason to doubt that there are. At the same time, there are a number of reasons why it matters. For suppose that there are indeed no such propositions. One might then hope that while paradoxes such as the Liar show that many plausible principles about sentences must be given up, no such fate will befall (...) principles about propositions. But the existence of self-referential propositions would dash such hopes. Further, the existence of such propositions would also seem to challenge the widespread claim that Liar sentences fail to express propositions. The aim of this paper is thus to settle the question–at least given an assumption. In particular, I argue that if propositions are structured, then self-referential propositions exist. (shrink)

The Italian Dominican Ptolemy of Lucca figures among the most significant political theoreticians of the Middle Ages. In his De regimine principum, a continuation of Thomas Aquinas’ De regno, Ptolemy paints a highly original picture of civil happiness. Taking the Roman Republic as his model, Ptolemy praises the “political” government that is presented as a sufficient condition for felicitas civilis, and this through the virtue of its citizens, the balance of its forces, and the harmonious and active collaboration of the (...) various groups that constitute the community.

Bruno Latour is among the most important figures in contemporary philosophy and social science. His ethnographic studies have revolutionized our understanding of areas as diverse as science, law, politics and religion. To facilitate a more realistic understanding of the world, Latour has introduced a radically fresh philosophical terminology and a new approach to social science, ‘Actor-Network Theory’. In seminal works such as Laboratory Life, We Have Never Been Modern and An Inquiry into Modes of Existence, Latour has outlined an (...) alternative to the foundational categories of ‘modern’ western thought Ð particularly its distinction between society and nature Ð that has major consequences for our understanding of the ecological crisis and of the role of science in democratic societies. Latour’s ‘empirical philosophy’ has evolved considerably over the past four decades. In this lucid and compelling book, Gerard de Vries provides one of the first overviews of Latour’s work. He guides readers through Latour’s main publications, from his early ethnographies to his more recent philosophical works, showing with considerable skill how Latour’s ideas have developed. This book will be of great value to students and scholars attempting to come to terms with the immense challenge posed by Latour’s thought. It will be of interest to those studying philosophy, anthropology, sociology, science and technology studies, and almost all other branches of the social sciences and humanities. (shrink)

Just War Theory is becoming increasingly important to nations when they contemplate and participate in war. This book recognizes the timeliness of the topic and so seeks, in concrete historical terms, to deal with the issue of constraining war on the basis of moral principles.

Many young dreamers who want to be modern up to the tips of their toes, and who think they have gotten rid of these barely imaginable old-fashioned ideas, are, without realizing it, mystics in search of a spiritual experience. Several sociologists of science have mobilized secularization metaphors to describe developments in the study of science. Similar to how secularization refers to a decreasing status of religion and God as a transcendent factor in society, the secularization of science refers to an (...) abandonment of Science as something “sacred” and Nature as transcendent. This article aims to explore these secularization metaphors, by arguing for a parallel between how sociologists and philosophers of religion differ and how similar disagreements between sociologists of science and the work of Bruno Latour exist, whose work should rather be linked with that of other philosophers, such as Michel Serres and Isabelle Stengers.

Der soziotechnische Wandel bringt neue Phänomene des Zufalls hervor, die sich den üblichen Strategien des Umgangs mit Risiken und Unsicherheit entziehen. Diese Akzidenzphänomene sind prinzipiell unvorhersehbar und in ihrer komplexen Effektgesamtheit jenseits von Kalkulation und Antizipation. Eine allgemeine Verzukünftigung unseres Weltbezuges mit spezifischen weitreichenden Problemen ist die Folge und lässt klassische Agenturen des Risikomanagements und der Unsicherheitsbewältigung an ihre Leistungsgrenzen stoßen.
