A long-standing challenge to evolutionary theory has been whether it can explain the origin of complex organismal features. We examined this issue using digital organisms—computer programs that self-replicate, mutate, compete and evolve. Populations of digital organisms often evolved the ability to perform complex logic functions requiring the coordinated execution of many genomic instructions. Complex functions evolved by building on simpler functions that had evolved earlier, provided that these were also selectively favoured. However, no particular intermediate stage was essential for evolving (...) complex functions. The first genotypes able to perform complex functions differed from their non-performing parents by only one or two mutations, but differed from the ancestor by many mutations that were also crucial to the new functions. In some cases, mutations that were deleterious when they appeared served as stepping-stones in the evolution of complex features. These findings show how complex functions can originate by random mutation and natural selection. (shrink)

Evolution has shaped all living organisms on Earth, although many details of this process are shrouded in time. However, it is possible to see, with one's own eyes, evolution as it happens by performing experiments in defined laboratory conditions with microbes that have suitably fast generations. The longest‐running microbial evolution experiment was started in 1988, at which time twelve populations were founded by the same strain ofEscherichia coli. Since then, the populations have been serially propagated and have evolved for tens (...) of thousands of generations in the same environment. The populations show numerous parallel phenotypic changes, and such parallelism is a hallmark of adaptive evolution. Many genetic targets of natural selection have been identified, revealing a high level of genetic parallelism as well. Beneficial mutations affect all levels of gene regulation in the cells including individual genes and operons all the way to global regulatory networks. Of particular interest, two highly interconnected networks—governing DNA superhelicity and the stringent response—have been demonstrated to be deeply involved in the phenotypic and genetic adaptation of these experimental populations.

Biological evolution provides a creative fount of complex and subtle adaptations, often surprising the scientists who discover them. However, because evolution is an algorithmic process that transcends the substrate in which it occurs, evolution’s creativity is not limited to nature. Indeed, many researchers in the field of digital evolution have observed their evolving algorithms and organisms subverting their intentions, exposing unrecognized bugs in their code, producing unexpected adaptations, or exhibiting outcomes uncannily convergent with ones in nature. Such stories routinely reveal (...) creativity by evolution in these digital worlds, but they rarely fit into the standard scientific narrative. Instead they are often treated as mere obstacles to be overcome, rather than results that warrant study in their own right. The stories themselves are traded among researchers through oral tradition, but that mode of information transmission is inefficient and prone to error and outright loss. Moreover, the fact that these stories tend to be shared only among practitioners means that many natural scientists do not realize how interesting and lifelike digital organisms are and how natural their evolution can be. To our knowledge, no collection of such anecdotes has been published before. This paper is the crowd-sourced product of researchers in the fields of artificial life and evolutionary computation who have provided first-hand accounts of such cases. It thus serves as a written, fact-checked collection of scientifically important and even entertaining stories. In doing so we also present here substantial evidence that the existence and importance of evolutionary surprises extends beyond the natural world, and may indeed be a universal property of all complex evolving systems.

Animals have had a profound influence on human societies, playing a major role in the course of human history. However, their presence and theoretical significance has been overlooked in sociological theory, while being the central concern of the growing field of anthrozoology (the study of the interaction between humans and other animals). To illustrate how a focus on other animal species can improve our understanding of sociocultural evolution, we assess the influential work of Gerhard Lenski and Patrick Nolan and (...) their materialist approach to macrosociology. Animals are largely invisible in Lenski and Nolan’s Ecological-Evolutionary Theory, yet they underlie the key subsistence technologies identified by Lenski and Nolan as crucial for explaining uneven development. By considering the history of domestication, the role animals played in the development of agricultural technology, and the translocation of Eurasian livestock during the colonial era, we show how sociocultural evolution is situated within a larger nexus of socioecological and historical conditions that reciprocally determine technological development and cultural heritage. Our analysis illustrates that anthrozoology, far from being an esoteric field of study, has the potential to contribute to a refined understanding of a wide array of social phenomena. (shrink)

A selection of speeches and essays from the author's second decade as president of Yale University.

The renowned biologist and thinker Richard Dawkins presents his most expansive work yet: a comprehensive look at evolution, ranging from the latest developments in the field to his own provocative views. Loosely based on the form of Chaucer's Canterbury Tales, Dawkins's Tale takes us modern humans back through four billion years of life on our planet. As the pilgrimage progresses, we join with other organisms at the forty "rendezvous points" where we find a common ancestor. The band of pilgrims (...) swells into a vast crowd as we join first with other primates, then with other mammals, and so on back to the first primordial organism. Dawkins's brilliant, inventive approach allows us to view the connections between ourselves and all other life in a bracingly novel way. It also lets him shed bright new light on the most compelling aspects of evolutionary history and theory: sexual selection, speciation, convergent evolution, extinction, genetics, plate tectonics, geographical dispersal, and more. The Ancestor's Tale is at once a far-reaching survey of the latest, best thinking on biology and a fascinating history of life on Earth. Here Dawkins shows us how remarkable we are, how astonishing our history, and how intimate our relationship with the rest of the living world. (shrink)

The discussion of good and evil must not be confined to the sterile lecture halls of academics but related instead to ordinary human feelings, needs, and desires, says noted philosopher Richard Taylor. Efforts to understand morality by exploring human reason will always fail because we are creatures of desire as well. All morality arises from our intense and inescapable longing. The distinction between good and evil is always clouded by rationalists who convert the real problems of ethics into complex (...) philosophical puzzles. In the first part of Good and Evil, Taylor looks for a more meaningful conception by reexamining and rejecting the whole rationalistic tradition that dominates philosophical ethics. The second part provides an empirical explanation of good and evil, noting that one does not have to look too far to find prime examples of the failure of fixed moral rules. Including important commentary on Joseph Fletcher's groundbreaking situation ethics, and Aristotle's virtues (e.g., magnanimity and pride), Taylor rounds out the book by developing a philosophy of aspiration--personal worth as an ethical ideal--to replace the morality of duty. He offers a modified form of situation ethics to fit the contemporary problems we face. (shrink)

Orientalism and Religion offers us a timely discussion of the implications of contemporary post-colonial theory for the study of religion. Drawing on a variety of post-structuralist and post-colonial thinkers, including Foucault, Gadamer, Said, and Spivak, Richard King examines the way in which notions such as mysticism, religion, Hinduism and Buddhism are taken for granted, and shows us how religion needs to be redescribed along the lines of cultural studies.

This is the third edition of a classic book first published in 1960, which has sold thousands of copies in two paperback edition and has been translated into several foreign languages. Popkin's work ha generated innumerable citations, and remains a valuable stimulus to current historical research. In this updated version, he has revised and expanded throughout, and has added three new chapters, one on Savonarola, one on Henry More and Ralph Cudworth, and one on Pascal. This authoritative treatment of the (...) theme of scepticism and its historical impact will appeal to scholars and students of early modern history now as much as ever. (shrink)

Conditionalization is one of the central norms of Bayesian epistemology. But there are a number of competing formulations, and a number of arguments that purport to establish it. In this paper, I explore which formulations of the norm are supported by which arguments. In their standard formulations, each of the arguments I consider here depends on the same assumption, which I call Deterministic Updating. I will investigate whether it is possible to amend these arguments so that they no longer depend (...) on it. As I show, whether this is possible depends on the formulation of the norm under consideration. (shrink)

The Desire-as-Belief thesis (DAB) states that any rational person desires a proposition exactly to the degree that she believes or expects the proposition to be good. Many people take David Lewis to have shown the thesis to be inconsistent with Bayesian decision theory. However, as we show, Lewis's argument was based on an Invariance condition that itself is inconsistent with the (standard formulation of the) version of Bayesian decision theory that he assumed in his arguments against DAB. The aim of (...) this paper is to explore what impact the rejection of Invariance has on the DAB thesis. Without assuming Invariance, we first refute all versions of DAB that entail that there are only two levels of goodness. We next consider two theses according to which rational desires are intimately connected to expectations of (multi-levelled) goodness, and show that these are consistent with Bayesian decision theory as long as we assume that the contents of 'value propositions' are not fixed. We explain why this conclusion is independently plausible, and show how to construct such propositions. (shrink)

Strangers, Gods and Monster is a fascinating look at how human identity is shaped by three powerful but enigmatic forces. Often overlooked in accounts of how we think about ourselves and others, Richard Kearney skillfully shows, with the help of vivid examples and illustrations, how the human outlook on the world is formed by the mysterious triumvirate of strangers, gods and monsters. Throughout, Richard Kearney shows how strangers, gods and monsters do not merely reside in myths or fantasies (...) but constitute a central part of our cultural unconscious. Above all, he argues that until we understand better that the Other resides deep within ourselves, we can have little hope of understanding how our most basic fears and desires manifest themselves in the external world and how we can learn to live with them.

Hilbert’s program was an ambitious and wide-ranging project in the philosophy and foundations of mathematics. In order to “dispose of the foundational questions in mathematics once and for all,” Hilbert proposed a two-pronged approach in 1921: first, classical mathematics should be formalized in axiomatic systems; second, using only restricted, “finitary” means, one should give proofs of the consistency of these axiomatic systems. Although Gödel’s incompleteness theorems show that the program as originally conceived cannot be carried out, it had many partial (...) successes, and generated important advances in logical theory and metatheory, both at the time and since. The article discusses the historical background and development of Hilbert’s program, its philosophical underpinnings and consequences, and its subsequent development and influences since the 1930s.

Most recent accounts of will-power have tried to explain it as reducible to the operation of beliefs and desires. In opposition to such accounts, this paper argues for a distinct faculty of will-power. Considerations from philosophy and from social psychology are used in support.

Most individuals realise that we have a moral obligation to avoid the evils of war. But this realization raises a host of difficult questions when we, as responsible individuals, witness harrowing injustices such as ""ethnic cleansing"" in Bosnia or starvation in Somalia. With millions of lives at stake, is war ever justified? And, if so, for what purpose? In this book, Richard J. Regan confronts these controversial questions by first considering the basic principles of just-war theory and then applying (...) those principles to historical and ongoing conflicts. Part One presents two opposing viewpoints: first, that war is not subject to moral norms and, second, that war is never morally permissible. The author rejects both perspectives, and moves to define the principles of just-war theory. He evaluates the roles of the president, Congress and, most importantly, the UN Security Council in determining when long-term US military involvement is justified. The moral limits of war conduct and the moral problem of using, or threatening to use, nuclear weapons are also discussed. On the just cause to wage war, Regan argues that defense of nations and nationals - whether in self-defense or in defense of others - remains the ""only"" classical cause that in the modern world would justify resorting to war. With respect to military intervention in secessionist and revolutionary wars, he contends that such intervention might be justified, but that prudence dictates extreme caution. In considering acceptable war conduct, Regan elaborates the specific principle of discrimination and proportionality; he maintains that civilians uninvolved in the enemy's war should not be directly targeted and that the costs of military action must be proportionate to the anticipated benefits of destroying military targets. The second part of the book presents case studies of eight historical wars - World War I, the Vietnam War, the Falklands War, the revolution and civil war in Nicaragua, the civil war in El Salvador, the Gulf War, the intervention in Somalia, and the Bosnian War - and poses several provocative questions about each. It invites readers and students to apply just-war principles to complex war-related situations and to understand the factual contingencies involved in moral judgements about war decisions. The book should be of particular interest to students of the moral issues of international relations and to readers interested more generally in philosophy, theology and political science. (shrink)

This book gives a descriptive analysis of specific Madhyamika texts. It compares the ideology of Kumarajiva (a translator of the four Madhyamika treatises 400 A.D.) with the ideologies of the three Chinese contemporaries - HuiYuan, Seng-Jui and Seng-Chao. It envisages an intercultural transmission of religious and philosophical ideas from India to China.

In “Theories of Justification,” Richard Fumerton begins an overview of several prominent positions on the nature of justification by isolating epistemic justification from nonepistemic justification. He also distinguishes between “having justification for a belief” and “having a justified belief,” arguing that the former is conceptually more fundamental. Fumerton then addresses the possibility that justification is a normative matter, suggesting that this possibility has little to offer as a concept of epistemic justification. He also critically examines more specific attempts to (...) capture the structure and content of epistemic justification. These include traditional foundationalism and variants thereof, externalist versions of foundationalism, contextualism, coherentism, and “mixed” theories which combine aspects of coherentism and foundationalism.

A comprehensive exploration of the philosophical issues raised by mysticism. This work is a comprehensive study of the philosophical issues raised by mysticism. Mystics claim to experience reality in a way not available in normal life, a claim which makes this phenomenon interesting from a philosophical perspective. Richard H. Jones’s inquiry focuses on the skeleton of beliefs and values of mysticism: knowledge claims made about the nature of reality and of human beings; value claims about what is significant and (...) what is ethical; and mystical goals and ways of life. Jones engages language, epistemology, metaphysics, science, and the philosophy of mind. Methodological issues in the study of mysticism are also addressed. Examples of mystical experience are drawn chiefly from Buddhism and Advaita Vedanta, but also from Christianity, Judaism, Islam, and Daoism. “This is a significant extension of the seminal work by Walter Stace, Mysticism and Philosophy. That work has stimulated much literature, all of which Jones manages to review here. He critically extends Stace’s universal core and embeds it in a sophisticated discussion of the extent, range, and metaphysical implications of mysticism.” — Ralph W. Hood, Jr., coauthor of The Psychology of Religion: An Empirical Approach. (shrink)

Logical Forms explains both the detailed problems involved in finding logical forms and also the theoretical underpinnings of philosophical logic. In this revised edition, exercises are integrated throughout the book. The result is a genuinely interactive introduction which engages the reader in developing the argument. Each chapter concludes with updated notes to guide further reading.

In this paper I defend what I call the argument from epistemic reasons against the moral error theory. I argue that the moral error theory entails that there are no epistemic reasons for belief and that this is bad news for the moral error theory since, if there are no epistemic reasons for belief, no one knows anything. If no one knows anything, then no one knows that there is thought when they are thinking, and no one knows that they (...) do not know everything. And it could not be the case that we do not know that there is thought when we believe that there is thought and that we do not know that we do not know everything. I address several objections to the claim that the moral error theory entails that there are no epistemic reasons for belief. It might seem that arguing against the error theory on the grounds that it entails that no one knows anything is just providing a Moorean argument against the moral error theory. I show that even if my argument against the error theory is indeed a Moorean one, it avoids Streumer's, McPherson's and Olson's objections to previous Moorean arguments against the error theory and is a more powerful argument against the error theory than Moore's argument against external world skepticism is against external world skepticism.

What system of morals should rational people select as the best for society? Using a contemporary psychological theory of action and of motivation, Richard Brandt's Oxford lectures argue that the purpose of living should be to strive for the greatest good for the largest number of people. Brandt's discussions range from the concept of welfare to conflict between utilitarian moral codes and the dictates of self-interest.

According to certain normative theories in epistemology, rationality requires us to be logically omniscient. Yet this prescription clashes with our ordinary judgments of rationality. How should we resolve this tension? In this paper, I focus particularly on the logical omniscience requirement in Bayesian epistemology. Building on a key insight by Hacking :311–325, 1967), I develop a version of Bayesianism that permits logical ignorance. This includes: an account of the synchronic norms that govern a logically ignorant individual at any given time; (...) an account of how we reduce our logical ignorance by learning logical facts and how we should update our credences in response to such evidence; and an account of when logical ignorance is irrational and when it isn’t. At the end, I explain why the requirement of logical omniscience remains true of ideal agents with no computational, processing, or storage limitations. (shrink)

At least since Darwin's Origin of Species was published in 1859, it has increasingly become accepted that the existence of God is, intellectually, a lost cause, and that religious faith is an entirely non-rational matter--the province of those who willingly refuse to accept the dramatic advances of modern cosmology. Are belief in God and belief in science really mutually exclusive? Or, as noted philosopher of science and religion Richard Swinburne puts forth, can the very same criteria which scientists use (...) to reach theories about everything from DNA to the Big Bang be used to argue for the existence of God? In Is There a God? Swinburne presents a powerful and approachable case for the existence of God. Using the methods of scientific reasoning, Swinburne rigorously argues that science, far from replacing God, provides good grounds for belief in God. With each new discovery and advance, from black holes to quarks, superstrings to continuing evolution, science brings us closer to a complete understanding of how things work--but science can only go so far. Though it can explain much of how the universe works, science doesn't tell us why there is a universe at all. We can understand much of how life evolved, but why is there any life on earth? We can name and explicate scientific laws, but how is it that they operate in the universe? The Darwinian theory holds that the complex animal and human bodies that are here today exist because, ages ago, there were certain chemicals on earth, and given the laws of evolution, it was probable that complex organisms would emerge. But why those laws rather than any other? Why those chemicals? In Swinburne's view, the ultimate grand unifying theory is possible only by a belief in what he calls theism, acknowledging the existence of God: it was God who brought about the natural laws so that humans and animals would evolve. The watch may have been made, Swinburne asserts in reference to Richard Dawkins, with the aid of some blind screwdrivers (or even a blind watchmaking machine), but they were guided by a watchmaker with some very clear sight. At the heart of his argument is Swinburne's belief that the very success of science in showing us how deeply ordered the natural world is provides strong grounds for believing there is an even deeper cause of that order. By embracing a belief in God that acknowledges the truth in science, Swinburne's elegant argument supplies an essential spiritual element to our understanding of order and beauty, the structure beneath the chaos of the natural world. This informed and provocative volume will be essential reading for all readers of popular science, philosophy, and religion. (shrink)

When making decisions, people naturally face uncertainty about the potential consequences of their actions due in part to limits in their capacity to represent, evaluate or deliberate. Nonetheless, they aim to make the best decisions possible. In Decision Theory with a Human Face, Richard Bradley develops new theories of agency and rational decision-making, offering guidance on how 'real' agents who are aware of their bounds should represent the uncertainty they face, how they should revise their opinions as a result (...) of experience and how they should make decisions when lacking full awareness of, or precise opinions on relevant contingencies. He engages with the strengths and flaws of Bayesian reasoning, and presents clear and comprehensive explorations of key issues in decision theory, from belief and desire to semantics and learning. His book draws on philosophy, economics, decision science and psychology, and will appeal to readers in all of these disciplines. (shrink)

"Ce livre propose une enquête philosophique explorant le rapport à la mort dans nos sociétés. C’est une invitation à penser les liens humains à la fin de la vie. On évoque les liens intimes, mais également les liens sociaux encadrés par la loi. Dans un tel contexte, comment discerner les raisons anciennes et nouvelles convenant au bien de la cité? L’ouvrage s’adresse aux accompagnants en soins palliatifs. Il concerne également toute personne soucieuse pour elle-même et ses proches de réfléchir à (...) son voyage au bout de la vie. Nous sommes mortels, nous le savons et le fil de nos existences provoque des occasions de nous le rappeler. Dans la solitude de mourir s’inscrit l’appel à la compassion. Ainsi, pour les Grecs de l’Antiquité, l’image de la cigogne symbolisait la prise en charge des vieux par les jeunes, un signe de l’amitié politique. L’émergence de la culture palliative est intimement liée aux changements qui ont affecté l’évolution récente de la vie démocratique. Cette culture est née et s’est développée dans des circonstances politiques particulières. À l’observer, on peut déchiffrer certains codes de notre vie civique, ses aspirations, mais aussi ses ambiguïtés. Louis-André Richard propose d’examiner les questions actuelles en compagnie de Platon, d’Aristote, d’Augustin ou de Tocqueville. Grâce à eux, la philosophie, symbolisée par la sagesse de Minerve, est mise à contribution pour explorer la genèse et les métamorphoses de concepts comme la dignité et l’autonomie. Comment se déploie la dynamique de la raison et de la liberté à l’heure de notre mort? Tel est l’enjeu pour les roseaux pensants que nous sommes. Si notre frêle espèce appelle à la sollicitude de la cigogne, elle ne saurait négliger de convoquer aussi la sagesse de Minerve."--Résumé de l'éditeur. (shrink)

At present, there is an enormous gulf between the visibility of evil and the paucity of our intellectual resources for coming to grips with it. We have been flooded with images of death camps, terrorist attacks and horrendous human suffering. Yet when we ask what we mean by radical evil and how we are to account for it, we seem to be at a loss for proper responses. Bernstein seeks to discover what we can learn about the meaning of evil (...) and human responsibility. He turns to philosophers such as Kant, who coined the expression 'radical evil', as well as to Hegel and Schelling. He also examines more recent explorations of evil, namely the thinking of Freud and Nietzsche on the moral psychology of evil. Finally, he looks at the way in which three post-Holocaust thinkers - Emmanuel Levinas, Hans Jonas, and Hannah Arendt - have sought to come to grips with evil "after Auschwitz." Bernstein's primary concern throughout this challenging book is to enrich and deepen our understanding of evil in the contemporary world, and to emphasize the vigilance and personal responsibility required for combating it. Radical Evil will be essential reading for students and scholars of philosophy, social and political theory, and religious studies. (shrink)

Ethics for Journalists tackles many of the issues which journalists face in their everyday lives-- from the media's supposed obsession with sex, sleaze and sensationalism, to issues of regulation and censorship. Its accessible style and question and answer approach highlights the relevance of ethical issues for everyone involved in journalism, both trainees and professionals, whether working in print, broadcast or new media.

What is it for there to be a God, and what reason is there for supposing him to conform to the claims of Christian doctrine? In this pivotal volume of his tetralogy, Richard Swinburne builds a rigorous metaphysical system for describing the world, and applies this to assessing the worth of the Christian tenets of the Trinity and the Incarnation. Part I is dedicated to analyzing the categories needed to address accounts of the divine nature--substance, cause, time, and necessity. (...) Part II begins by setting out, in terms of these categories, the fundamental doctrine of Western religions--that there is a God. After pointing out some of the different ways in which this doctrine can be developed, Swinburne spells out the simplest possible account of divine nature. He then goes on to clarify the implications of this account for the specifically Christian doctrines of the Trinity (that God is "three persons in one substance") and of the Incarnation (that God became incarnate in Jesus Christ). Swinburne finds that there are good reasons to believe the Christian additions to the core Western idea of God. The Christian God builds upon Swinburne's acclaimed previous work to form a self-contained text which will no doubt become a classic in the philosophy of religion. (shrink)
