It is posited that the initiating event of amphibian regeneration of a limb, is retrodifferentiation* of what are to become the developing cells of the blastema. These cells reiterate a larval or premetamorphic ontogenic repertoire, induced by elevated levels of prolactin with adequate innervation. Subsequent redifferentiation of the blastema cells occurs, controlled by thyroxine and innervation.This temporal displacement of cellular morphologic characters in regeneration should be looked upon as a function of the ability to reiterate larval characters and subsequently metamorphose. (...) If correct, this would explain why amphibians which metamorphose only once, lose the ability to postmetamorphically regenerate. An exception to this,Xenopus laevis, an anuran which can epimorphically regenerate, to some extent, will be discussed.[/p]. (shrink)

Regeneration in arthropods and amphibians follows an analogous principle making comparisons between the two phyla possible.Larval arthropods and amphibians possess powers of epimorphic regeneration which wane for many species of these phyla with the completion of metamorphosis or the cessation of moulting. In those species which retain, post-maturationally, the ability to form a regenerative blastema, larval characteristics are carried into the adult and reproductive stages of these organisms. These include many species of: urodeles, ametabolous insects, crustaceans, myriapods and arachnids. The (...) long-standing distinction between embryonic regulation and true epimorphosis would thus appear to be a difference of degree rather than kind. (shrink)

Variation or rearrangement of regulatory genes is responsible for cellular malignant change. These types of chromosomal variations also produce heterochrony or paedomorphic evolution at the organismal level. Analogously, neoplasia represents a cellular macroevolutionary event, and a tumour can be said to be an evolved population of cells. To understand this cellular evolution to malignancy, it may be necessary to go beyond a clonal selection (adaptationist) explanation of neoplastic alteration. In the pericellular environment natural selection consists of the organizational restraints of (...) surrounding cells as well as the host's immunological surveillance and non-specific monocyte-macrophage systems. Indirect evidence suggests that success for the neoplasm depends not upon clonal selection, but solely upon a genetic methodology—the function of which is to elude selection.The author has coined the term cellular heterochrony to illustrate analogic similarities in the molecular modes of speciation between anaplastic cancer cells and the heterochronic evolution of organisms. By reverting to a juvenile (embryonic) repertoire of cellular behaviour a tumour secures its own tenure or niche by usurping the host's armamentarium of selection forces, employing many of the same or similar methods by which implanting and invading tissues of the mammalian embryo forestall maternal detection and rejection. A number of ways by which the tumour blocks, subverts or evades selection are discussed. (shrink)

The philosophy of science as it is known today emerged out of a combination of three traditional concerns: the classification of the sciences, methodology and the philosophy of nature. Included in the series Works in the Philosophy of Science 1830-1914 are all three of these interrelated areas. The titles should be of interest to both the philosopher of science and to the historian of ideas. The former will be able to trace present-day concerns back to their origins; the latter should (...) find it a useful source for the study of Victorian conceptions of science. (shrink)

"Clifford was famous for his public lectures on physics and math and ethics because he explained complex things with easily understood, concrete examples. As you read through his clear, simple explanations of the true bases of number, algebra and geometry you will find yourself getting angry and saying "Why the hell wasn't I taught math this way?" and "Do math ed professors know so little mathematics that they have never heard of Clifford.?" Clifford was destined to be England's Einstein until (...) his untimely death at the age of 34, just 11 days before Einstein's birth. More than 30 years before the Special Theory of Relativity was proposed he had already concluded that the force of gravity was actually due to changes in the curvature of space.

_'Nagel and Newman accomplish the wondrous task of clarifying the argumentative outline of Kurt Godel's celebrated logic bomb.'_ _– The Guardian_ In 1931 the mathematical logician Kurt Godel published a revolutionary paper that challenged certain basic assumptions underpinning mathematics and logic. A colleague of physicist Albert Einstein, his theorem proved that mathematics was partly based on propositions not provable within the mathematical system. The importance of Godel's Proof rests upon its radical implications and has echoed throughout many fields, from maths (...) to science to philosophy, computer design, artificial intelligence, even religion and psychology. While others such as Douglas Hofstadter and Roger Penrose have published bestsellers based on Godel’s theorem, this is the first book to present a readable explanation to both scholars and non-specialists alike. A gripping combination of science and accessibility, _Godel’s Proof_ by Nagel and Newman is for both mathematicians and the idly curious, offering those with a taste for logic and philosophy the chance to satisfy their intellectual curiosity. _Kurt Godel_ Born in Brunn, he was a colleague of physicist Albert Einstein and professor at the Institute for Advanced Study in Princeton, N.J.

Do Quine and Carnap distort the social nature of inquiry by privileging individual epistemic subjects? This objection is at the heart of Donald Davidson’s claim that Quine fails to grasp the significance of the concept of truth. In Carnap’s case, the objection may be detected in Charles Morris’s call to ground scientific philosophy in semiotics, the science of signs, rather than syntax, the formal investigation of languages. Drawing out the challenge from Morris’s proposal requires examining a neglected influence on this (...) neglected philosopher: his advisor George Herbert Mead’s social theory of mind. I argue that Morris and Davidson can both be understood as demanding that scientific philosophers socialize their conception of objectivity. (shrink)

In a brilliant series of studies, Roy Bhaskar, the originator of the influential, multi-disciplinary and international philosophy of critical realism, presents for the first time in published form, his new philosophy of Meta-Reality. The philosophy of Meta-Reality confirms many aspects of the great philosophical traditions of the past, while correcting their one-sidedness and transcending their dualism and dichotomies, representing what is valid in them in a radically new way, apt for our contemporary times of global crisis.

The paper argues against Peacocke's moderate rationalism in modality. In the first part, I show, by identifying an argumentative gap in its epistemology, that Peacocke's account has not met the Integration Challenge. I then argue that we should modify the account's metaphysics of modal concepts in order to avoid implausible consequences with regards to their possession conditions. This modification generates no extra explanatory gap. Yet, once the minimal modification that avoids those implausible consequences is made, the resulting account cannot support (...) Peacocke's moderate rationalism. (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)

This unique collection of studies, based for the most part on transcripts of talks in India, Europe and America over the last five years, covers the period in which Roy Bhaskar was developing out of the seeds of the most radical phase of critical realism, his new philosophy of meta-Reality. Because of the spontaneous and informal nature of these talks and discussions, this book provides probably the most immediately accessible introduction to his thought, both for those new to it and (...) those already familiar with it alike.

In his most audacious and radical book to date, Bhaskar develops his existing philosophy of dialectical critical realism into a philosophy of and for universal self-realization (which he also terms a transcendental critical realism). In a general theoretical introduction, Bhaskar establishes the existence of God as the fundamental categorical structure of the world and unconditional love as the cement of the universe. This system of thought is followed by a narrative novella designed to render plausible the ideas of reincarnation, karma (...) and moksha, or liberation, and to support an ethic of engaged but unattached activity in the world.

Can God create a stone too heavy for him to lift? Can time have a beginning? Which came first, the chicken or the egg? Riddles, paradoxes, conundrums--for millennia the human mind has found such knotty logical problems both perplexing and irresistible. Now Roy Sorensen offers the first narrative history of paradoxes, a fascinating and eye-opening account that extends from the ancient Greeks, through the Middle Ages, the Enlightenment, and into the twentieth century. When Augustine asked what God was doing before (...) He made the world, he was told: "Preparing hell for people who ask questions like that." A Brief History of the Paradox takes a close look at "questions like that" and the philosophers who have asked them, beginning with the folk riddles that inspired Anaximander to erect the first metaphysical system and ending with such thinkers as Lewis Carroll, Ludwig Wittgenstein, and W.V. Quine. Organized chronologically, the book is divided into twenty-four chapters, each of which pairs a philosopher with a major paradox, allowing for extended consideration and putting a human face on the strategies that have been taken toward these puzzles. Readers get to follow the minds of Zeno, Socrates, Aquinas, Ockham, Pascal, Kant, Hegel, and many other major philosophers deep inside the tangles of paradox, looking for, and sometimes finding, a way out. Filled with illuminating anecdotes and vividly written, A Brief History of the Paradox will appeal to anyone who finds trying to answer unanswerable questions a paradoxically pleasant endeavor.

There are two alternative approaches to accommodating an agent-centered restriction against, say, φ-ing. One approach is to prohibit agents from ever φ-ing. For instance, there could be an absolute prohibition against breaking a promise. The other approach is to require agents both to adopt an end that can be achieved only by their not φ-ing and to give this end priority over that of minimizing overall instances of φ-ing. For instance, each agent could be required both to adopt the end (...) of minimizing their own promise-breakings and to give this end priority over that of minimizing promise-breakings overall. The former is what I’ll call the side-constraint approach, and the latter is what I’ll call the teleological approach. In this chapter, I argue that, when it comes to accommodating restrictions, we should (1) favor the teleological approach over the side-constraint approach, (2) favor an act-consequentialist approach over a non-consequentialist, teleological approach (such as Rossian pluralism), and (3) favor a Kantsequentialist approach over other act-consequentialist approaches, where Kantsequentialism is a version of act-consequentialism that holds that persons are ends-in-themselves who are inherently and unconditionally valuable and are, thus, owed our respect.

Fundamentals of Critical Argumentation presents the basic tools for the identification, analysis, and evaluation of common arguments for beginners. The book teaches by using examples of arguments in dialogues, both in the text itself and in the exercises. Examples of controversial legal, political, and ethical arguments are analyzed. Illustrating the most common kinds of arguments, the book also explains how to evaluate each kind by critical questioning. Douglas Walton shows how arguments can be reasonable under the right dialogue conditions (...) by using critical questions to evaluate them. The book teaches by example, both in the text itself and in exercises, but it is based on methods that have been developed through the author's thirty years of research in argumentation studies.

The paper compares the suitability of two different epistemologies of counterfactuals—(EC) and (W)—to elucidate modal knowledge. I argue that, while both of them explain the data on our knowledge of counterfactuals, only (W)—Williamson’s epistemology—is compatible with all counterpossibles being true. This is something on which Williamson’s counterfactual-based account of modal knowledge relies. A first problem is, therefore, that, in the absence of further, disambiguating data, Williamson’s choice of (W) is objectionably biased. A second, deeper problem is that (W) cannot satisfactorily (...) elucidate modal knowledge. Third, from a naturalistic perspective, the nature of this second problem favours (EC) against (W).

Is the flavor of mint reducible to the minty smell, the taste, and the menthol-like coolness on the roof of one’s mouth, or does it include something over and above these—something not properly associated with any one of the contributing senses? More generally, are there features of perceptual experiences—so-called novel features—that are not associated with any of our senses taken singly? This question has received a lot of attention of late. Yet surprisingly little attention has been paid to the question (...) of what it means to say that a feature is associated with a sensory modality in the first place. Indeed, there is only one fully developed proposal in the literature, due to Casey O’Callaghan. I argue that this proposal is too permissive to inform the debate over novel features. I go on to argue that all attempts to formulate a better proposal along these lines fail. The corollary of my arguments is that the question of the existence of novel features is poorly formed. Furthermore, the problem generalizes, with the result that we should not rely on our pre-theoretical notions of the senses as the basis of theorizing about the features of perceptual experiences.

The finding that women are attracted to men older than themselves whereas men are attracted to relatively younger women has been explained by social psychologists in terms of economic exchange rooted in traditional sex-role norms. An alternative evolutionary model suggests that males and females follow different reproductive strategies, and predicts a more complex relationship between gender and age preferences. In particular, males' preferences for relatively younger females should be minimal during early mating years, but should become more pronounced as the (...) male gets older. Young females are expected to prefer somewhat older males during their early years and to change less as they age. We briefly review relevant theory and present results of six studies testing this prediction. Study 1 finds support for this gender-differentiated prediction in age preferences expressed in personal advertisements. Study 2 supports the prediction with marriage statistics from two U.S. cities. Study 3 examines the cross-generational robustness of the phenomenon, and finds the same pattern in marriage statistics from 1923. Study 4 replicates Study 1 using matrimonial advertisements from two European countries, and from India. Study 5 finds a consistent pattern in marriages recorded from 1913 through 1939 on a small island in the Philippines. Study 6 reveals the same pattern in singles advertisements placed by financially successful American women and men. We consider the limitations of previous normative and evolutionary explanations of age preferences and discuss the advantages of expanding previous models to include the life history perspective.

Following on from Roy Bhaskarâe(tm)s first two books, A Realist Theory of Science and The Possibility of Naturalism, Scientific Realism and Human Emancipation, establishes the conception of social science as explanatoryâe"and thence emancipatoryâe"critique. Scientific Realism and Human Emancipation starts from an assessment of the impasse of contemporary accounts of science as stemming from an incomplete critique of positivism. It then proceeds to a systematic exposition of scientific realism in the form of transcendental realism, highlighting a conception of science as explanatory (...) of a structured, differentiated and changing world. Turning to the social domain, the book argues for a view of the social order as conditioned by, and emergent from, nature. Advocating a critical naturalism, the author shows how the transformational model of social activity together with the conception of social science as explanatory critique which it entails, resolves the divisions and dualisms besetting orthodox social and normative theory: between society and the individual, structure and agency, meaning and behavior, mind and body, reason and cause, fact and value, and theory and practice. The book then goes on to discuss the emancipatory implications of social science and sketches the nature of the depth investigation characteristically entailed. In the highly innovative third part of the book Roy Bhaskar completes his critique of positivism by developing a theory of philosophical discourse and ideology, on the basis of the transcendental realism and critical naturalism already developed, showing how positivism functions as a restrictive ideology of and for science and other social practices.

It seems that we can be directly accountable for our reasons-responsive attitudes—e.g., our beliefs, desires, and intentions. Yet, we rarely, if ever, have volitional control over such attitudes, volitional control being the sort of control that we exert over our intentional actions.

Since its inception in the 1970's, critical realism has grown to address a broad range of subjects, including economics, philosophy, science, and religion. It has also gone through a number of key evolutions that have changed its direction, and seen it develop into a complex and mature branch of philosophy. Critical Realism: A Brief Introduction, is the first book to look back over the entire field of critical realism in one concise and accessible volume. As the originator and chief exponent (...) of CR, Roy Bhaskar draws from his experience of countless introductory lectures, seminars, workshops and courses to give a definitive and compelling account of this increasingly influential, international and multi-disciplinary approach. Its eight chapters examine the following topics: Transcendental Realism and the Philosophy of Science Critical Naturalism and the Philosophy of Social Science Explanatory Critique and Ethics Language and Critical Discourse Analysis The Development of Critical Realism Interdisciplinarity and Applied Critical Realism Modernity, Theories of Science and Metacritique The Advantages of Critical Realism Everything from the definition of CR and its applicability to the social sciences, to explanations of dialectical critical realism and the philosophy of meta-reality are addressed in detail, making this the essential introduction for students of CR at all levels.

Second edition of the introductory guidebook to the basic principles of constructing sound arguments and criticising bad ones. Non-technical in approach, it is based on 186 examples, which Douglas Walton, a leading authority in the field of informal logic, discusses and evaluates in clear, illustrative detail. Walton explains how errors, fallacies, and other key failures of argument occur. He shows how correct uses of argument are based on sound strategies for reasoned persuasion and critical responses. This edition takes into (...) account many developments in the field of argumentation study that have occurred since 1989, many created by the author. Drawing on these developments, Walton includes and analyzes 36 new topical examples and also brings in work on argumentation schemes. Ideally suited for use in courses in informal logic and introduction to philosophy, this book will also be valuable to students of pragmatics, rhetoric, and speech communication. (shrink)

In this paper, I take it for granted both that there are two types of blameworthiness—accountability blameworthiness and attributability blameworthiness—and that avoidability is necessary only for the former. My task, then, is to explain why avoidability is necessary for accountability blameworthiness but not for attributability blameworthiness. I argue that what explains this is both the fact that these two types of blameworthiness make different sorts of reactive attitudes fitting and that only one of these two types of attitudes requires having (...) been able to refrain from φ-ing in order for them to be fitting.

Nietzsche regarded Thus Spoke Zarathustra as his most important philosophical contribution because it proposes solutions to the problems and questions he poses in his later books – for example, his cure for the human disposition to vengefulness and his creation of new values as the antidote to nihilism. It is also the only place where he elaborates his concepts of the superhuman and the eternal recurrence of the same. In this Critical Guide, an international group of distinguished scholars analyze the (...) philosophical ideas in Thus Spoke Zarathustra, discussing a range of topics that include literary parody as philosophical critique, philosophy as a way of life, the meaning of human life, philosophical naturalism, fatalism, radical flux, human passions and virtues, great politics, transhumanism, and ecological conscience.

Some right acts have what philosophers call moral worth. A right act has moral worth if and only if its agent deserves credit for having acted rightly in this instance. And I argue that an agent deserves credit for having acted rightly if and only if her act issues from an appropriate set of concerns, where the appropriateness of these concerns is a function what her ultimate moral concerns should be. Two important upshots of the resulting account of moral worth (...) are that (1) an act can have moral worth even if it doesn’t manifest a concern for doing what’s right and that (2) an act can lack moral worth even if it is performed for the right reasons.

_Dialectic_ is now widely regarded as a classic of contemporary philosophy. This book, first published in 1993, sets itself three main aims: the development of a general theory of dialectic, of which Hegelian dialectic can be seen to be a special case; the dialectical enrichment and deepening of critical realism, viz. into the system of dialectical critical realism; and the outline of the elements of a totalizing critique of Western philosophy. The first chapter clarifies the rational core of Hegelian dialectic. (...) Chapter two then proceeds to develop a general theory of dialectic. Isolating the fallacy of 'ontological monovalence', Roy Bhaskar then shows how absence and other negating concepts such as contradiction have a legitimate and necessary ontological employment. He then goes on to give a synoptic account of key dialectical concepts such as the concrete universal; to sketch the further dialectical development of critical naturalism through an account of what he calls four-planar social being; and following consideration of the dialectical critique of analytical reason, he moves on to the real definition of dialectic as absenting absence and in the human sphere, the axiology of freedom. Chapter three extends and deepens critical realism’s characteristic concerns with ontology, science, social science and emancipation not only into the realms of negativity and totality, but also into the fields of reference and truth, spatio-temporality, tense and process, the logic of dialectical universalizability and on to the plane of ethics, where it articulates a combination of moral realism and ethical naturalism, whereby consideration of elemental desire involves commitment to the eudaimonistic society. This is then followed by a sublime discussion of key moments in the trajectory of Western philosophy, the tradition of which can now be seen to be based on what the author calls the unholy trinity of the epistemic fallacy or the reduction of being to knowledge, primal squeeze or the collapse of structure and alethic truth, and ontological monovalence.

Originally published in 1989, Reclaiming Reality still provides the most accessible introduction to the increasingly influential multi-disciplinary and international body of thought, known as critical realism. It is designed to "underlabour" both for the sciences, especially the human sciences, and for the projects of human emancipation which such sciences may come to inform; and provides an enlightening intervention in current debates about realism and relativism, positivism and poststucturalism, modernism and postmodernism, etc. Elaborating his critical realist perspective on society, nature, science (...) and philosophy itself, Roy Bhaskar shows how this perspective can be used to undermine currently fashionable ideologies of the Right, and at the same time, to clear the ground for a reinvigorated Left. Reclaiming Reality contains powerful critiques of some of the most important schools of thought and thinkers of recent years—from Bachelard and Feyerabend to Rorty and Habermas; and it advances novel and convincing resolutions of many traditional philosophical problems. Now with a new introduction from Mervyn Hartwig, this book continues to provide a straightforward and stimulating introduction to current debates in philosophy and social theory for the interested lay reader and student alike. Reclaiming Reality will be of particular value not only for critical realists but for all those concerned with the revitalization of the socialist emancipatory project and the renaissance of the Marxist theoretical tradition. Roy Bhaskar is the originator of the philosophy of critical realism, and the author of many acclaimed and influential works including A Realist Theory of Science, The Possibility of Naturalism, Scientific Realism and Human Emancipation and Dialectic: The Pulse of Freedom. He is an editor of the recently published Critical Realism: Essential Readings and is currently chair of the Centre for Critical Realism. (shrink)

Argumentation, which can be abstractly defined as the interaction of different arguments for and against some conclusion, is an important skill to learn for everyday life, law, science, politics and business. The best way to learn it is to try it out on real instances of arguments found in everyday conversational exchanges and legal argumentation. The introductory chapter of this book gives a clear general idea of what the methods of argumentation are and how they work as tools that can (...) be used to analyze arguments. Each subsequent chapter then applies these methods to a leading problem of argumentation. Today the field of computing has embraced argumentation as a paradigm for research in artificial intelligence and multi-agent systems. Another purpose of this book is to present and refine tools and techniques from computing as components of the methods that can be handily used by scholars in other fields. (shrink)
