Since Darwin, the idea of psychological continuity between humans and other animals has dominated theory and research in investigating the minds of other species. Indeed, the field of comparative psychology was founded on two assumptions. First, it was assumed that introspection could provide humans with reliable knowledge about the causal connection between specific mental states and specific behaviors. Second, it was assumed that in those cases in which other species exhibited behaviors similar to our own, similar psychological causes were at (...) work. In this paper. we show how this argument by analogy is flowed with respect to the case of second-order mental states. As a test case, we focus on the question of how other species conceive of visual attention, and in particular whether chimpanzees interpret seeing as a mentalistic event involving internal states of perception, attention, and belief. We conclude that chimpanzees do not reason about seeing in this manner, and indeed, there is considerable reason to suppose that they do not harbor representations of mental states in general. We propose a reinterpretation model in which the majority of the rich social behaviors that humans and other primates share in common emerged long before the human lineage evolved the psychological means of interpreting those behaviors in mentalistic terms. Although humans, chimpanzees, and most other species may be said to possess mental states, humans alone may have evolved a cognitive specialization for reasoning about such states. (shrink)

No other scientific theory has had as tremendous an impact on our understanding of the world as Darwin's theory as outlined in his Origin of Species, yet from the very beginning the theory has been subject to controversy. The Evolution of Darwinism focuses on three issues of debate - the nature of selection, the nature and scope of adaptation, and the question of evolutionary progress. It traces the varying interpretations to which these issues were subjected from the beginning and the (...) fierce contemporary debates that still rage on and explores their implications for the greatest questions of all: Where we come from, who we are and where we might be heading. Written in a clear and non-technical style, this book will be of use as a textbook for students in the philosophy of science who need to become familiar with the background to the debates about evolution.

Does natural selection act primarily on individual organisms, on groups, on genes, or on whole species? The question of levels of selection - on which biologists and philosophers have long disagreed - is central to evolutionary theory and to the philosophy of biology. Samir Okasha's comprehensive analysis gives a clear account of the philosophical issues at stake in the current debate.

Als Charles Darwin im Jahr 1859 seine Theorie einer Evolution der Arten durch natürliche Auslese veröffentlichte, sah er bereits eine grosse Debatte voraus, jedoch nicht deren Ausstrahlungskraft und Langlebigkeit. Zu Beginn standen die Folgen für die Wissenschaften, den Glauben an Gott und die Moralvorstellungen im Vordergrund. Bald kamen Überlegungen über Gesellschaft, Politik, internationale Beziehungen und über Eingriffe bis hinunter auf die Ebene des Individuums und seines Erbmaterials, seiner Gene hinzu. Sozialdarwinismus, Eugenik, Rassismus galten zeitweise als wissenschaftlich legitime Diskussions- und Politikfelder. (...) Befürchtungen vor einem vermeintlichen Niedergang lassen sich bis heute angesichts der Biologisierung des Denkens scheinbar wissenschaftlich-objektiv untermauern. Gegenwärtig sind die Kontroversen noch vielfältiger, beziehen weit mehr Menschen ein als im späten 19. Jahrhundert, haben weit gravierendere Auswirkungen. Die aus elf Ländern stammenden Autorinnen und Autoren zeichnen aus unterschiedlichen disziplinären Perspektiven die Facetten einer spannenden und bis in die Gegenwart hochaktuellen Debatte nach und fragen nach der Zukunft des "Streitfalls Evolution".

Der Wandel der kulturellen Verhältnisse führt zu einer Zuspitzung des Verhältnisses von Gesellschaft und Rechtssystem. In diesem Prozess gestaltet New Political Ecology (NPE) Umwelt und Rechtssystem und ist zugleich evolutiv ausgerichtet. NPE erfährt Evolution in der Zeit als Überfluss und in eigenartiger Vernetzung als knappes Gut. Diese Verbindung basiert auf Zusammenhängen, die bisher noch nicht systematisch bearbeitet worden sind. Dabei geht es ganz wesentlich auch um das Verhältnis von Staat und moderner Risikogesellschaft. Wissenschaftlicher Fortschritt erweist sich vor diesem Hintergrund selbst (...) als ein evolutiver Prozess. (shrink)

The US-Australia strategic relationship has evolved from more or less an adversarial position in the 19th century to an Australia largely dependent on the US during the Cold War to the interdependent partnership we see today. Strategic interdependence means that the US-Australia relationship is not merely a one-sided affair; that Australia has something of substance to offer the strategic relationship. Part of the reason that the relationship is strong is because of a shared language, similar social values, and compatible political-legal (...) systems. Moreover, the relationship has been thoroughly institutionalised via intelligence cooperation, defence science collaboration, and extensive personal relationships. But what the US really seems to value is Australia’s reliability as an ally. I argue that Australia best demonstrates its reliability as an ally, however, when it follows US strategic decision-making for the right reasons. This sense of reliability is more akin to trustworthiness than it is to loyalty. History demonstrates that Australia has not always agreed with the US. But agreeing doesn’t matter so much when Australia has established a track record of consistently applying sound reasoning to its strategic decisions and it has made substantive contributions to jointly sought after strategic outcomes.

Evolution and ethics: prolegomena--Evolution and ethics.--Science and morals.--Capital, the mother of labour.--Social diseases and worse remedies.

This remarkable book presents a rich and up-to-date view of evolution that explores the far-reaching implications of Darwin's theory and emphasizes the power, significance, and relevance of evolution to our lives today. After all, we ourselves are the product of evolution, and we can tackle many of our gravest challenges -- from lethal resurgence of antiobiotic-resistant diseases to the wave of extinctions that looms before us -- with a sound understanding of the science.

This book presents a collection of linked essays written by one of the leading philosophers of biology, Kim Sterelny, on the topic of biological evolution. The first half of the book explores most of the main theoretical controversies about evolution and selection. Sterelny argues that genes are not the only replicators: non-genetic inheritance is also extremely important, and is no mere epiphenomenon of gene selection. The second half of the book applies some of these ideas in considering cognitive evolution. Concentrating (...) on the mental capacities of simpler animals rather than those of humans, Sterelny argues for a general distinction between detection and representation, and that the evolution of belief, like that of representation, can be decoupled from the evolution of preference. These essays, some never before published, form a coherent whole that defends not just an overall conception of evolution, but also a distinctive take on cognitive evolution. (shrink)

Descartes boldly claimed: "I think, therefore I am." But one might well ask: Why do we think? How? When and why did our human ancestors develop language and culture? In other words, what makes the human mind human? _Evolution of Mind, Brain, and Culture_ offers a comprehensive and scientific investigation of these perennial questions. Fourteen essays bring together the work of archaeologists, cultural and physical anthropologists, psychologists, philosophers, geneticists, a neuroscientist, and an environmental scientist to explore the evolution of the (...) human mind, the brain, and the human capacity for culture. The volume represents and critically engages major theoretical approaches, including Donald's stage theory, Mithen's cathedral model, Tomasello's joint intentionality, and Boyd and Richerson's modeling of the evolution of culture in relation to climate change. The volume contains chapters by: Peter Carruthers; Thierry Chaminade; Philip Chase; Merlin Donald; Peter Gardenfors; Gary Hatfield; Jody Hey; Steven Mithen; April Nowell; Peter Richerson and Robert Boyd; Theodore Schurr; Robert Seyfarth and Dorothy Cheney; Kim Sterelny; and Felix Warneken.

In Darwin’s Dangerous Idea, Daniel Dennett claims that evolution is algorithmic. On Dennett’s analysis, evolutionary processes are trivially algorithmic because he assumes that all natural processes are algorithmic. I will argue that there are more robust ways to understand algorithmic processes that make the claim that evolution is algorithmic empirical and not conceptual. While laws of nature can be seen as compression algorithms of information about the world, it does not follow logically that they are implemented as algorithms by physical (...) processes. For that to be true, the processes have to be part of computational systems. The basic difference between mere simulation and real computing is having proper causal structure. I will show what kind of requirements this poses for natural evolutionary processes if they are to be computational. (shrink)

In this controversial new book O'Hear takes a stand against the fashion for explaining human behavior in terms of evolution. He contends that while the theory of evolution is successful in explaining the development of the natural world in general, it is of limited value when applied to the human world. Because of our reflectiveness and our rationality we take on goals and ideals which cannot be justified in terms of survival-promotion or reproductive advantage. O'Hear examines the nature of human (...) self-consciousness, and argues that evolutionary theory cannot give a satisfactory account of such distinctive facets of human life as the quest for knowledge, moral sense, and the appreciation of beauty; in these we transcend our biological origins. It is our rationality that allows each of us to go beyond not only our biological but also our cultural inheritance: as the author says in the Preface, "we are prisoners neither of our genes nor of the ideas we encounter as we each make our personal and individual way through life.".

Purpose. Reconstruction of Empedocles’ doctrine from the point of view of philosophical anthropology. Theoretical basis. Methodological basis of the article is the anthropological comprehending of Empedocles’ text fragments presented in the historical-philosophical context. Originality. Cognition of nature in Ancient Greece was far from the ideal of the objective knowledge formed in modern times, cognition of the world as it exists before man and independently of him. Whatever the ancient philosophers talked about, man was always in the center of their attention. (...) I proposed an anthropological version of the interpretation of the doctrine of Empedocles, within the framework of which various elements of his concept fit into a consistent model. Conclusions. Empedocles’ anthropology is based on the recognition of several fundamental things. First of all, there is no death. Second, there is no fundamental difference between human and celestial. This line is conventional and under certain conditions one can overcome it. Cod can become a human, and a human can become God. Teaching of evolution is also double. Not only physical shell evolves, keeping only the most adapted species, but the soul too. The latter can both ascend to the gods and go down to the bushes and fish. Purification of the soul and mastering the magic of the elements gives an impetus for a correct direction of evolution. Empedocles is an anthropologist-practitioner, who shows by his example that a human can cope with all the elements and reach divinity. He chose the elemental ingredients for penetrating the Fortunate Isles, leaving the instructions on how to become God. (shrink)

In 1894, the British sociologist Benjamin Kidd published Social Evolution, an influential book that summarised and evaluated the prevailing social theories at the end of the nineteenth century: Karl Marx's socialism and Herbert Spencer's social Darwinism. Both of these conflicting theories were based on Darwinian evolutionary theory. In this book, Kidd discusses the immense changes that applied science has brought to the world and the interconnectedness of everyone. The book's ten chapters include discussions of the conditions of human progress, the (...) function of religious beliefs, and the organisation of the working classes. Kidd found flaws in both Karl Marx's and Herbert Spencer's vision of society's future and concluded that religion was essential for the evolution of society because it acts in the interest of generational group survival rather than individual competition. Social Evolution called for a comprehensive study of society because a new era in Western civilisation was beginning. (shrink)

Both the concept of a Darwinian tree of life (TOL) and the possibility of its accurate reconstruction have been much criticized. Criticisms mostly revolve around the extensive occurrence of lateral gene transfer (LGT), instances of uptake of complete organisms to become organelles (with the associated subsequent gene transfer to the nucleus), as well as the implications of more subtle aspects of the biological species concept. Here we argue that none of these criticisms are sufficient to abandon the valuable TOL concept (...) and the biological realities it captures. Especially important is the need to conceptually distinguish between organismal trees and gene trees, which necessitates incorporating insights of widely occurring LGT into modern evolutionary theory. We demonstrate that all criticisms, while based on important new findings, do not invalidate the TOL. After considering the implications of these new insights, we find that the contours of evolution are best represented by a TOL. (shrink)

Are non-human animals conscious? When do babies begin to feel pain? What function is served by consciousness? What evidence could resolve these issues? In The Evolution of Consciousness, psychologist Euan Macphail tackles these questions and more by exploring such topics as: animal cognition; unconscious learning and perception in humans; infantile amnesia; theory of mind in primates; and the nature of pleasure and pain. Experimental results are placed in theoretical context by tracing the development of concepts of consciousness in animals and (...) humans. Written in an accessible style, this book will be of interest to students and professionals in psychology, philosophy, and linguistics, as well as all those interested in the nature of consciousness.

Stephen Jay Gould argued that replaying the ‘tape of life’ would result in radically different evolutionary outcomes. Recently, biologists and philosophers of science have paid increasing attention to the theoretical importance of convergent evolution—the independent origination of similar biological forms and functions—which many interpret as evidence against Gould’s thesis. In this paper, we examine the evidentiary relevance of convergent evolution for the radical contingency debate. We show that under the right conditions, episodes of convergent evolution can constitute valid natural experiments (...) that support inferences regarding the deep counterfactual stability of macroevolutionary outcomes. However, we argue that proponents of convergence have problematically lumped causally heterogeneous phenomena into a single evidentiary basket, in effect treating all convergent events as if they are of equivalent theoretical import. As a result, the ‘critique from convergent evolution’ fails to engage with key claims of the radical contingency thesis. To remedy this, we develop ways to break down the heterogeneous set of convergent events based on the nature of the generalizations they support. Adopting this more nuanced approach to convergent evolution allows us to differentiate iterated evolutionary outcomes that are probably common among alternative evolutionary histories and subject to law-like generalizations, from those that do little to undermine and may even support, the Gouldian view of life.

Treating mathematical science as a distinct cultural entity subject to environmental factors which influence its evolution, the author examines the creation and development of its major concepts since early times.

In this important volume Habermas outlines the views which form the basis of his critical theory of modern societies. The volume comprises five interlocking essays, which together define the contours of his theory of communication and of his substantive account of social change. ′What is Universal Pragmatics?′ is the best available statement of Habermas′s programme for a theoryof communication based on the analysis of speech acts. In the following two essays Habermas draws on the work of Kohlberg and others to (...) develop a distinctive account of moral consciousness and normative structures. ′Toward a Reconstruction of historical Materialsim′ takes these issues further, offering a wide–ranging reconstruction of Marx′s historical materialsim understood as a theory of social evolution. The final essay focuses on the question of legitimacy and on the legitimation problems faced by modern states. This book is essential reading for anyone concerned with the key questions of social and political theory today. (shrink)

Originally published in 1910, Principia Mathematica led to the development of mathematical logic and computers and thus to information sciences. It became a model for modern analytic philosophy and remains an important work. In the late 1960s the Bertrand Russell Archives at McMaster University in Canada obtained Russell's papers, letters and library. These archives contained the manuscripts for the new Introduction and three Appendices that Russell added to the second edition in 1925. Also included was another manuscript, 'The Hierarchy of (...) Propositions and Functions', which was divided up and re-used to create the final changes for the second edition. These documents provide fascinating insight, including Russell's attempts to work out the theorems in the flawed Appendix B, 'On Induction'. An extensive introduction describes the stages of the manuscript material on the way to print and analyzes the proposed changes in the context of the development of symbolic logic after 1910.

With human language, the same utterance can have different meanings in different contexts. Nevertheless, listeners almost invariably converge upon the correct intended meaning. The classic Gricean explanation of how this is achieved posits the existence of four maxims of conversation, which speakers are assumed to follow. Armed with this knowledge, listeners are able to interpret utterances in a contextually sensible way. This account enjoys wide acceptance, but it has not gone unchallenged. Specifically, Relevance Theory offers an explicitly cognitive account of (...) utterance interpretation that presents a radical challenge to the neo‐Gricean paradigm. Evolutionary considerations are one way in which we can choose between competing theories. A simple game‐theoretic model of the evolution of communication is presented, and it is used to derive a number of basic qualities that will be satisfied by all evolved communication systems. These qualities are observed to precisely predict the foundational principles of Relevance Theory. The model thus provides biological support for that enterprise in general, and for the plausibility of the cognitive mechanisms that it describes in particular. (shrink)

"One of the many merits of this book is that it places Western scholasticism in its setting--and this both in space and in time. Plotinus lives on, Aristotle comes back to life again, Averroes breaks in--but this is not the right word, for this Muslim philosopher and his Western Christian disciples are inmates of the same house. Professor Knowles brings out the unity of Islamic and Western Christian culture. Medieval Islam and Western Christendom had a common mental heritage of Jewish (...) religion and Greek philosophy; both were stimulated intellectually by a tension between the Judaic and the Hellenic pole of their thought; and the same stimulus led thinkers in both provinces of this Judaistic-Hellenistic Christian-Muslim world to interest themselves in the same problems."--In The Observer (London).

No fight over what gets taught in American classrooms is more heated than the battle over humanity’s origins. For more than a century we have argued about evolutionary theory and creationism (and its successor theory, intelligent design), yet we seem no closer to a resolution than we were in Darwin’s day. In this thoughtful examination of how we teach origins, historian Adam Laats and philosopher Harvey Siegel offer crucial new ways to think not just about the evolution debate but how (...) science and religion can make peace in the classroom. Laats and Siegel agree with most scientists: creationism is flawed, as science. But, they argue, students who believe it nevertheless need to be accommodated in public school science classes. Scientific or not, creationism maintains an important role in American history and culture as a point of religious dissent, a sustained form of protest that has weathered a century of broad—and often dramatic—social changes. At the same time, evolutionary theory has become a critical building block of modern knowledge. The key to accommodating both viewpoints, they show, is to disentangle belief from knowledge. A student does not need to believe in evolution in order to understand its tenets and evidence, and in this way can be fully literate in modern scientific thought and still maintain contrary religious or cultural views. Altogether, Laats and Siegel offer the kind of level-headed analysis that is crucial to finding a way out of our culture-war deadlock. (shrink)

Extraterrestrial Altruism examines a basic assumption of the Search for Extraterrestrial Intelligence (SETI): that extraterrestrials will be transmitting messages to us for our benefit. This question of whether extraterrestrials will be altruistic has become increasingly important in recent years as SETI scientists have begun contemplating transmissions from Earth to make contact. Technological civilizations that transmit signals for the benefit of others, but with no immediate gain for themselves, certainly seem to be altruistic. But does this make biological sense? Should we (...) expect altruism to evolve throughout the cosmos, or is this only wishful thinking? Is it dangerous to send messages to other worlds, as Stephen Hawking has suggested, or might humankind benefit from an exchange with intelligence elsewhere in the galaxy? Would extraterrestrial societies be based on different ethical principles, or would we see commonalities with Earthly notions of morality? Extraterrestrial Altruism explores these and related questions about the motivations of civilizations beyond Earth, providing new insights that are critical for SETI. Chapters are authored by leading scholars from diverse disciplines—anthropology, astronomy, biology, chemistry, computer science, cosmology, engineering, history of science, law, philosophy, psychology, public policy, and sociology. The book is carefully edited by Douglas Vakoch, Director of Interstellar Message Composition at the SETI Institute and professor of clinical psychology at the California Institute of Integral Studies. The Foreword is by Frank Drake. This interdisciplinary book will benefit everybody trying to understand whether evolution and ethics are unique to Earth, or whether they are built into the fabric of the universe. (shrink)

Initiated by Robert Wesson, _Evolution and Human Values_ is a collection of newly written essays designed to bring interdisciplinary insight to that area of thought where human evolution intersects with human values. The disciplines brought to bear on the subject are diverse - philosophy, psychiatry, behavioral science, biology, anthropology, psychology, biochemistry, and sociology. Yet, as organized by co-editor Patricia A. Williams, the volume falls coherently into three related sections. Entitled Evolutionary Ethics, the first section brings contemporary research to an area (...) first explored by Herbert Spencer. Evolutionary ethics looks to the theory of evolution by natural selection to find values for human living. The second section, Evolved Ethics, discusses the evolution of language and religion and their impact on moral thought and feeling. Evolved ethics was partly Charles Darwin's subject in _The Descent of Man._ The last section bears the title Scientific Ethics. A nascent field, scientific ethics asks about the evolution of human nature and the implications of that nature for ethical theory and social policy. Together, the essays collected here provide important contemporary insights into what it is - and what it may be - to be human. (shrink)

EMERGENT EVOLUTION- THE GIFFORD LECTURES DELIVERED IN THE UNIVERSITY OF ST.

Let us now imagine that some administrative authority, as far superior in power and intelligence to men, as men are to their cattle, is set over the colony, charged to deal with its human elements in such a manner as to assure the victory of the settlement over the antagonistic influences of the state of nature in which it is set down. He would proceed in the same fashion as that in which the gardener dealt with his garden.

Humans are moral creatures. Among all life on Earth, we alone experience rich moral emotions, follow complex rules governing how we treat one another, and engage in moral dialogue. But how did human morality evolve? And can humans become morally evolved? -/- In A Better Ape, Victor Kumar and Richmond Campbell draw on the latest research in the biological and social sciences to explain the key role that morality has played in human evolution. They explore the moral traits that humans (...) share with chimpanzees; how a more complex moral mind enabled Homo sapiens to arise and out-compete other human species; and the place of morality alongside historic revolutions in technology and social organization. Throughout the book, Kumar and Campbell argue that morality co-evolved with intelligence and complex sociality. Morality prevents societal collapse and enables complex knowledge. -/- After unearthing the ancient origins of human morality, Kumar and Campbell use evolutionary theory to deliver profound insights about how to advance moral progress and resist moral regress, such as reducing animal suffering on industrial farms; capitalizing on the recent revolution in gay rights to foster a nascent revolution in transgender rights; opposing intersectional inequality that impacts women and people of color in lower socioeconomic classes; and addressing major problems of global inequality, especially impending crises of injustice caused by anthropogenic climate change. Understanding how we evolved--and how we continue to evolve--can help us become a better ape. (shrink)

This volume reaches beyond the controversy surrounding the teaching and learning of evolution in the United States, specifically in regard to the culture, politics, and beliefs found in the Southeast.

In fact, scientists, educators, and researchers from around the United States have found their niche in the South, (...) where biodiversity is high, culture runs deep, and the pace is just a little bit slower.

Darwinian evolutionary theory has two key terms, variations and biological selection, which finally lead to survival of the fittest variant. With the rise of molecular genetics, variations were explained as results of error replications out of the genetic master templates. For more than half a century, it has been accepted that new genetic information is mostly derived from random error-based events. But the error replication narrative has problems explaining the sudden emergence of new species, new phenotypic traits, and genome innovations (...) as a sudden single event. Meanwhile, it is recognized that errors cannot explain the evolution of genetic information, genetic novelty, and complexity. Now, empirical evidence establishes the crucial role of non-random genetic content editors, such as viruses, diversity generating retroelements, and other RNA networks, to produce new genetic information, complex regulatory control, inheritance vectors, genetic identity, immunity, new sequence space, evolution of complex organisms, and evolutionary transitions.

Phenotypic Evolution explicitly recognizes organisms as complex genetic-epigenetic systems developing in response to changing internal and external environments. As a key to a better understanding of how phenotypes evolve, the authors have developed a framework that centers on the concept of the Developmental Reaction Norm. This encompasses their views: (1) that organisms are better considered as integrated units than as disconnected parts (allometry and phenotypic integration); (2) that an understanding of ontogeny is vital for evaluating evolution of adult forms (ontogenetic (...) trajectories, epigenetics, and constraints); and (3) that environmental heterogeneity is ubiquitous and must be acknowledged for its pervasive role in phenotypic expression.

In contrast to vertical gene transfer from parent to offspring, horizontal (or lateral) gene transfer moves genetic information between different species. Bacteria and archaea often adapt through horizontal gene transfer. Recent analyses indicate that eukaryotic genomes, too, have acquired numerous genes via horizontal transfer from prokaryotes and other lineages. Based on this we raise the hypothesis that horizontally acquired genes may have contributed more to adaptive evolution of eukaryotes than previously assumed. Current candidate sets of horizontally acquired eukaryotic genes may (...) just be the tip of an iceberg. We have recently shown that adaptation of the thermoacidophilic red algaGaldieria sulphurariato its hot, acid, toxic‐metal laden, volcanic environment was facilitated by the acquisition of numerous genes from extremophile bacteria and archaea. Other recently published examples of horizontal acquisitions involved in adaptation include ice‐binding proteins in marine algae, enzymes for carotenoid biosynthesis in aphids, and genes involved in fungal metabolism.Editor's suggested further reading in BioEssaysJumping the fine LINE between species: Horizontal transfer of transposable elements in animals catalyses genome evolution Abstract.

The intersection of development and evolution has always harbored conceptual issues, but many of these are on display in contemporary evolutionary developmental biology (evo-devo). These issues include: (1) the precise constitution of evo-devo, with its focus on both the evolution of development and the developmental basis of evolution, and how it fits within evolutionary theory; (2) the nature of evo-devo model systems that comprise the material of comparative and experimental research; (3) the puzzle of how to understand the widely used (...) notion of 'conserved mechanisms'; (4) the definition of evolutionary novelties and expectations for how to explain them; and (5) the demand of interdisciplinary collaboration that derives from investigating complex phenomena at key moments in the history of life, such as the fin-limb transition. This Element treats these conceptual issues with close attention to both empirical detail and scientific practice to offer new perspectives on evolution and development.
