Excerpt from An Introduction to Political Philosophy Political philosophy cannot be learnt from text-books. If it be true - "That nature always does contrive That every boy and every gal That's born into the world alive Is either a little Liberal, Or else a little Conservative," then the most interesting problems of political philosophy must remain matters of controversy. It is perhaps for this reason that students are generally asked to approach the subject by way of the study of the (...) writings of certain political philosophers that are generally regarded as classical. Or it may be because, as Aristotle said - "It would probably be right to suppose that not only these but all other political discoveries have been made repeatedly, or rather an infinite number of times in the lapse of ages... It is our duty then while we avail ourselves adequately of the discoveries of the past, to endeavour to fill up the deficiencies that remain" (Politics, Bk. IV. chap. 10).

The year 2009 has been a year of numerous commemorations of both scientific and non-scientific achievements that contributed to the advancement of human kind. Protestants celebrated the 500th anniversary of the birth of Calvin; literary critics celebrated the 200th anniversary of the poet Edgar Allan Poe; and the musical genius Felix Mendelssohn-Bartholdy was also born 200 years ago. 2009 further marked the bicentennial of the birth of Louis Braille, the inventor of Braille; and Abraham Lincoln, the 16th president of the (...) United States, who founded the National Academy of Sciences. Pierre Curie, famous for his work on radioactivity that he conducted together with his wife Marie Curie, was born 150 ago; as was John Dewey, a philosopher and psychologist who is recognized as one of the founding fathers of both pragmatism as well as functional psychology. UNESCO and the International Astronomical Union dubbed 2009 the International Year of Astronomy. By doing so, astronomers celebrated the 400th anniversary of Galileo Galilei’s telescopic observations as well as the publication of Johannes Kepler’s Astronomia nova wherein he formulated the first two laws of planetary motion. 2009 also marked the last of a 3-year-long celebration of Planet Earth, another UNESCO-governed initiative. However, for evolutionary biologists and philosophers of science, 2009 will be largely remembered for its worldwide commemorations of the 200th anniversary of the birth of Charles Darwin, and the 150th anniversary of the publication of his magnum opus On the origin of species by means of natural selection. Footnote1 In order to pay tribute to Darwin’s major contribution to the advancement of evolutionary science, the International Union of Biological Sciences and the International Union of History and Philosophy of Science have called the year 2009 the Darwin Year. Given that so many scientific discoveries were commemorated, COPUS, the Coalition on the Public Understanding on Science, called out 2009 as the Year of Science, in the hope to pay equal tribute to both the field of biology as well as astronomy. 2009 was indeed a year of biology. Somewhat overshadowed by the big Darwin celebrations, smaller-scaled events were held to commemorate the 200th anniversary of the publication of Lamarck’s Philosophie Zoologique; and the 150th anniversary of the death of Alexander von Humboldt, the father of biogeography. In 1910, Constantin Mereschkowsky wrote his article on symbiogenesis entitled ‘The Theory of Two Plasmas as the Basis of Symbiogenesis, a New Study for the Origins of Organisms’. The article was published in the German Biologisches Zentralblatt, the journal that would later evolve into the current Theory in Biosciences. Somewhat forgotten, but equally important for the field of symbiogenesis, was the 200th anniversary of the birth of Pierre-Joseph Van Beneden, a Belgian paleontologist and zoologist famous for distinguishing parasitism from commensalism. Finally, Henry Bergson, known for inventing the currently rejected notion of élan vital, was born 150 years ago. In order to memorialize the important role these biologists played in the advancement of our understanding of the evolutionary process, a 2-day international conference was organized entitled: Evolution today and tomorrow, Darwin evaluated by contemporary evolutionary and philosophical theories. The conference was organized by The Centre for Philosophy of Science of the University of Lisbon (Portugal), in collaboration with the Centre for Environmental Biology of the same university, and the Lisbon Centre for Applied Psychology. The articles presented here are a spin-off of this conference. The current volumes contain the peer-reviewed articles of a selection of the plenary and invited speakers, as well as those of scholars who were additionally invited to contribute to the volumes.

Radioactivity accompanied by ionizing radiation has always existed on the Earth, as well as in space, and so in every living tissue there are traces of radioactivity. With the discovery of the said radiation and identifying its effects on the human body, the fear of this phenomenon appeared. At high doses radiation causes serious tissue damages, while at small doses it can cause cancer and induce genetic defects. The best antidote for fear is knowledge. It is important (...) to know the margins safety of radiation for human life. As a result, the topic of radioactive contamination of the environment has now become one of the most significant. In recent years the radon problem is a subject of a wide debate of geologists, geophysicists, ecologists, physicians, specialists in radiometry, and, of course, philosophers and sociologists, since the need for assessing the potential radon danger concerns human lives, human functions in society, and human future.

In this work, Henry Vyverberg traces the evolution and consequences of a crucial idea in French Enlightenment thought--the idea of human nature. Human nature was commonly seen as a broadly universal, unchanging entity, though perhaps modifiable by geographical, social, and historical factors. Enlightenment empiricism suggested a degree of cultural diversity that has often been underestimated in studies of the age. Evidence here is drawn from Diderot's celebrated Encyclopedia and from a vast range of writing by such Enlightenment notables as Voltaire, (...) Rousseau, and d'Holbach. Vyverberg explains not only the age's undoubted fascination with uniformity in human nature, but also its acknowledgment of significant limitations on that uniformity. He shows that although the Enlightenment's historical sense was often blinkered by its notions of a uniform human nature, there were also cracks in this concept that developed during the Enlightenment itself.

Modernity is founded on the belief that the world we build is a human invention, not a part of nature. The ecological consequences of this idea have been catastrophic. We have laid waste to natural ecosystems, replacing them with fundamentally unsustainable human designs. With time running out to address the environmental crises we have caused, our best path forward is to turn to nature for guidance. In this book, Henry Dicks explores the philosophical significance of a revolutionary approach to (...) sustainable innovation: biomimicry. The term describes the application and adaptation of strategies found in nature to the development of artificial products and systems, such as passive cooling techniques modeled on termite mounds or solar cells modeled on leaves. Dicks argues that biomimicry, typically seen as just a design strategy, can also serve as the basis for a new environmental philosophy that radically alters how we understand and relate to the natural world. By showing how we can imitate, emulate, and learn from nature, biomimicry points us toward a genuinely sustainable way of inhabiting the earth. Rooted in philosophy, The Biomimicry Revolution has profound implications spanning the natural sciences, design, architecture, sustainability studies, science and technology studies, and the environmental humanities. It presents a sweeping reconception of what philosophy can be and offers a powerful new vision of terrestrial existence. (shrink)

It is often assumed that in the collapse of the Aristotelian distinction between art and nature that results from the rise of mechanical philosophies in the early modern period, the collapse falls on the side of art. That is, all of the diversity among natures that was explained previously as differences among substantial forms came to be seen simply as differences in arrangements of matter according to laws instituted by the “divine artificer”, God. This paper argues that, for René Descartes, (...) the collapse occurs on both sides. Natures are artefacts of God, and human artefacts, under some conditions, can be classified as natures or, at least, continuous within nature. Drawing on developments across both horticulture and engineering in the 16th and 17th centuries, as well as Descartes’ mechanical philosophy, this paper explores challenges to the Aristotelian nature/art distinction. The question then is what, in the advent of this collapse, are human artificers doing when they construct artefacts? Are they replicating God’s powers by creating new natures, or are they doing something else, and if so, what might that be? It is argued that we should view human invention for Descartes not as creating new natures so much as discovering them. These findings have consequences for how we interpret Descartes’ use of the term “nature” in relation to automata and other artefacts produced by human hands. (shrink)

In this paper I examine the role of optimality reasoning in Aristotle’s natural science. By “optimality reasoning” I mean reasoning that appeals to some conception of “what is best” in order to explain why things are the way they are. We are first introduced to this pattern of reasoning in the famous passage at Phaedo 97b8-98a2, where (Plato’s) Socrates invokes “what is best” as a cause (aitia) of things in nature. This passage can be seen as the intellectual ancestor (...) of Aristotle’s own principle, expressed by the famous dictum “nature does nothing in vain but always what is best for the substance from among the possibilities concerning each kind of animal” (Progression of Animals II, 704b12-18). The paper is focused around exploring three questions that arise in connection with Aristotle’s use of this optimality principle: (1) How do we understand the concept of “the best” at work in the principle? (2) How does Aristotle conceive of “the range of possibilities”? And, finally, (3) what role does optimality reasoning play in Aristotle’s natural science? Is it a special form of demonstration in which the optimality principle functions as one of its premises, or is it a heuristic device that helps uncover those causally relevant features of a natural substances that ultimately serve as middle terms in demonstrations? In the final section I return to the comparison between Plato and Aristotle and argue that, while both see the natural world as the product of an optimizing agent and while both see this assumption as licensing a pattern of reasoning that appeals to a certain conception of “the best”, they disagree fundamentally over what the optimization agent is and how it operates. Thus, despite their general agreement, it would be a mistake to think that Aristotle simply took over Plato’s use of optimality reasoning without significant modifications. (shrink)

The global production of radioactive wastes is expected to increase in the coming years as more countries have resorted to adopting nuclear power to decrease their reliance on fossil-fuel-generated energy. Discoveries of remediation methods that can remove radionuclides from radioactive wastes, including those discharged to the environment, are therefore vital to reduce risks-upon-exposure radionuclides posed to humans and wildlife. Among various remediation approaches available, microbe-mediated radionuclide remediation have limited reviews regarding their advances. This review provides an overview of the sources (...) and existing classification of radioactive wastes, followed by a brief introduction to existing radionuclide remediation (physical, chemical, and electrochemical) approaches. Microbe-mediated radionuclide remediation (bacterial, myco-, and phycoremediation) is then extensively discussed. Bacterial remediation involves biological processes like bioreduction, biosorption, and bioprecipitation. Bioreduction involves the reduction of water-soluble, mobile radionuclides to water-insoluble, immobile lower oxidation states by ferric iron-reducing, sulfate-reducing, and certain extremophilic bacteria, and in situ remediation has become possible by adding electron donors to contaminated waters to enrich indigenous iron- and sulfate-reducing bacteria populations. In biosorption, radionuclides are associated with functional groups on the microbial cell surface, followed by getting reduced to immobilized forms or precipitated intracellularly or extracellularly. Myco- and phycoremediation often involve processes like biosorption and bioaccumulation, where the former is influenced by pH and cell concentration. A Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis on microbial remediation is also performed. It is suggested that two research directions: genetic engineering of radiation-resistant microorganisms and co-application of microbe-mediated remediation with other remediation methods could potentially result in the discovery of in situ or ex situ microbe-involving radioactive waste remediation applications with high practicability. Finally, a comparison between the strengths and weaknesses of each approach is provided. (shrink)

Quantum theory is essentially a rationally coherent theory of the interaction of mind and matter, and it allows our conscious thoughts to play a causally efficacious and necessary role in brain dynamics. It therefore provides a natural basis, created by scientists, for the science of consciousness. As an illustration it is explained how the interaction of brain and consciousness can speed up brain processing, and thereby enhance the survival prospects of conscious organisms, as compared to similar organisms that lack (...) consciousness. As a second illustration it is explained how, within the quantum framework, the consciously experienced ``I'' directs the actions of a human being. It is concluded that contemporary science already has an adequate framework for incorporating causally efficacious experiential events into the physical universe in a manner that: 1) puts the neural correlates of consciousness into the theory in a well defined way, 2) explains in principle how the effects of consciousness, per se, can enhance the survival prospects of organisms that possess it, 3) allows this survival effect to feed into phylogenetic development, and 4) explains how the consciously experienced ``I'' can direct human behaviour.

In spite of vigorous opposition by a number of historians it has now become a commonplace that the rapid development of the ‘new philosophy’ sprang from the ideology of Puritanism. What began its career as the ‘Merton thesis’ has now been refined, developed, and so often repeated that it seems to be almost unassailable. However, the two foremost historians in the entrenchment of this new orthodoxy are willing, in principle, to concede that ‘in reality things were very mixed up’, and (...) that non-Puritan natural philosophers at the time were operating ‘in a precisely similar manner’ to their Puritan contemporaries. Indeed, it would be impossible not to concede this in the face of the many critiques launched against the Merton thesis. (shrink)

Noting that the doctrine of the general resurrection attracted renewed attention after the Reformation, and after the atomist revival led to the displacement of traditional hylomorphism by alternative matter theories, this article surveys the ways in which the resurrection was discussed by leading natural philosophers in seventeenth‐century England. These include discussion of how bodily resurrection might be possible, what resurrected bodies will be like; as well as the nature of living conditions after the resurrection. It is indicated that the (...) resurrection seems to have played a much less prominent place in the writings of natural philosophers than the doctrine of the immortality of the soul, and other issues of natural theology. Reasons for this lack of prominence are tentatively offered, chiefly focusing on its unsuitability for combatting the perceived atheism of the time. It is hoped that this preliminary survey might inspire others to extend the survey, especially to cover Continental philosophers. (shrink)

An abstract framework for structured arguments is presented, which instantiates Dung's ('On the Acceptability of Arguments and its Fundamental Role in Nonmonotonic Reasoning, Logic Programming, and n- Person Games', Artificial Intelligence , 77, 321-357) abstract argumentation frameworks. Arguments are defined as inference trees formed by applying two kinds of inference rules: strict and defeasible rules. This naturally leads to three ways of attacking an argument: attacking a premise, attacking a conclusion and attacking an inference. To resolve such attacks, preferences may (...) be used, which leads to three corresponding kinds of defeat: undermining, rebutting and undercutting defeats. The nature of the inference rules, the structure of the logical language on which they operate and the origin of the preferences are, apart from some basic assumptions, left unspecified. The resulting framework integrates work of Pollock, Vreeswijk and others on the structure of arguments and the nature of defeat and extends it in several respects. Various rationality postulates are proved to be satisfied by the framework, and several existing approaches are proved to be a special case of the framework, including assumption-based argumentation and DefLog.

Einstein's principle that no signal travels faster than light suggests that observations in one spacetime region should not depend on whether or not a radioactive decay is detected in a spacelike-separated region. This locality property is incompatible with the predictions of quantum theory, and this incompatibility holds independently of the questions of realism, objective reality, and hidden variables. It holds both in the pragmatic quantum theory of Bohr and in realistic frameworks. It is shown here to hold in a completed (...) realistic quantum theory that reconciles Einstein's demand for a description of reality itself with Bohr's contention that quantum theory is complete. This completed realistic quantum theory has no hidden variables, and no objective reality in which observable attributes can become definite independently of observers. The theory is described in some detail, with particular attention to those aspects related to the question of locality. This completed realistic quantum theory is in principle more comprehensive than Bohn's pragmatic quantum theory because it is not limited in principle by the requirement that the observed system be physically separated from the observing one. Applications are discussed. (shrink)

Recently, a new movement has arisen in the philosophy of perception: one that views perception as a natural kind. Strangely, this movement has neglected the extensive work in philosophy of science on natural kinds. The present paper remedies this. I start by isolating a widespread and influential assumption, which is that we can give necessary and sufficient conditions for perception. I show that this assumption is radically at odds with current philosophy of science work on natural kinds. (...) I then develop an alternative, new view of perception. This new view takes as its starting point the dominant position on kinds in the life sciences: the homeostatic property cluster account. I show that, if you accept this view, then all of the putative cases of unconscious perception are more plausibly seen as cases where it is indeterminate whether the mental episode in question is an instance of perception.

How is mind related to matter? This ancient question in philosophy is rapidly becoming a core problem in science, perhaps the most important of all because it probes the essential nature of man himself. The origin of the problem is a conflict between the mechanical conception of human beings that arises from the precepts of classical physical theory and the very different idea that arises from our intuition: the former reduces each of us to an automaton, while the latter allows (...) our thoughts to guide our actions. The dominant contemporary approaches to the problem attempt to resolve this conflict by clinging to the classical concepts, and trying to explain away our misleading intuition. But a detailed argument given here shows why, in a scientific approach to this problem, it is necessary to use the more basic principles of quantum physics, which bring the observer into the dynamics, rather than to accept classical precepts that are profoundly incorrect precisely at the crucial point of the role of human consciousness in the dynamics of human brains. Adherence to the quantum principles yields a dynamical theory of the mind/brain/body system that is in close accord with our intuitive idea of what we are. In particular, the need for a self-observing quantum system to pose certain questions creates a causal opening that allows mind/brain dynamics to have three distinguishable but interlocked causal processes, one micro-local, one stochastic, and the third experiential. Passing to the classical limit in which the critical difference between zero and the finite actual value of Planck's constant is ignored not only eliminates the chemical processes that are absolutely crucial to the functioning of actual brains, it simultaneously blinds the resulting theoretical construct to the physical fine structure wherein the effect of mind on matter lies: the use of this limit in this context is totally unjustified from a physics perspective.

Auguste Comte, writing of one of his forerunners, Montesquieu, said that the great merit of the latter's memorable work L'Esprit des Lois appeared to him to be in its tendency to regard political phenomena as subject to invariable laws like all other phenomena. Comte himself writes with regard to sociology: “the philosophical principle of the science being that social phenomena are subject to natural laws, admitting of rational prevision, we have to ascertain what is the precise subject, and what (...) the peculiar character of those laws.” “Such prevision,” says Comte in another place, “is a necessary consequence of the discovery of constant relations between phenomena, and it is the unfailing test which distinguishes real science from that erudition which mechanically accumulates facts without aspiring to deduce them one from another.” Elsewhere he speaks of “rational prevision, the principal characteristic of true science.” And Branford and Geddes quote his saying: “Savoir pour prévoir, prévoir pour pourvoir.”.

The author wishes to discover a way in which the philosophy of w v quine can be described relative to its place in the history of metaphysics. In order to facilitate such a classification, The author distinguishes between the aristotelian notion of metaphysics, As the study of being qua being or ultimate reality, And kant's transcendental approach in which it is admitted that only appearances can ever be described and that things can never be known as they are in themselves. (...) It is the author's contention that quine's metaphysics can most appropriately be understood as following in the tradition of kant's transcendentalism. The argument for this claim is based on quine's repeated assertion that the methods and procedures of metaphysics are continuous with those of the natural sciences. The logic of discovery in the sciences, However, Quine would consider to be not so much inductive as hypothetico-Deductive; and since hypotheses would appear to be neither verifiable nor falsifiable in any strict sense, The only alternative is to consider that such hypotheses are subject only to a transcendental justification.

This chapter focuses on the English response to Thomas Hobbes as a mechanical philosopher. Hobbes's mechanical philosophy was by no means merely derivative from Descartes's Principia philosophiae; indeed, Hobbes came closer than anyone else to developing a mechanistic system to match it. Hobbes's system was a carefully thought‐out and uniquely original system of mechanical philosophy, and none of his contemporaries, not even his staunchest critics, ever considered it to be simply derived from Cartesianism. An important aspect of the dispute between (...) Robert Boyle and Hobbes was concerned with the correct method to arrive at knowledge of the natural world. The distinctions between the thought of Hobbes and his critical contemporaries were by no means as stark as his critics wanted to maintain, but were highly nuanced. This can be seen in the marked similarity between Hobbes's concept of a corporeal God, and Henry More's influential concept of a supposedly immaterial but nonetheless three‐dimensionally extended God.

It is emphasized that a many-worlds interpretation of quantum theory exists only to the extent that the associated basis problem is solved. The core basis problem is that the robust enduring states specified by environmental decoherence effects are essentially Gaussian wave packets that form continua of non-orthogonal states. Hence they are not a discrete set of orthogonal basis states to which finite probabilities can be assigned by the usual rules. The natural way to get an orthogonal basis without going (...) outside the Schroedinger dynamics is to use the eigenstates of the reduced density matrix, and this idea is the basis of some recent attempts by many-worlds proponents to solve the basis problem. But these eigenstates do not enjoy the locality and quasi-classicality properties of the states defined by environmental decoherence effects, and hence are not satisfactory preferred basis states. This core problem is obscured by approaches that treat the universe as a quantum computer, but it needs to be addressed and resolved before a many-worlds-type interpretation can be said to exist.

[opening paragraph]: In his keynote paper David Chalmers defines ‘the hard problem’ by posing certain ‘Why’ questions about consciousness? Such questions must be posed within an appropriate setting. The way of science is to try to deduce the answer to many such questions from a few well defined assumptions. Much about nature can be explained in terms of the principles of classical mechanics. The assumptions, in this explanatory scheme, are that the world is composed exclusively of particles and fields governed (...) by specified mathematical laws that refer neither to any individual person, nor to anyone’s experiences. These physical laws are supposed to be such that particles and fields, acting in concert, can form causally efficacious real functional entities such as driveshafts and propellers. Similarly, surges of electrical and mechanical activity in appropriately designed material substrates, composed of particles and fields acting in concert, could implement, in the world of matter, complex functional structures and long sequences of logical operations. Thus it is conceivable that all of our behaviour, and all of the internal processing that occurs in our bodies and brains could be deduced, at least in principle, from the principles of classical mechanics and appropriate boundary conditions. -/- Contents: 1.

This book tells the curious story of an unexpected finding that sheds light on a crucial moment in the development of physics: the discovery of artificial radioactivity induced by neutrons. The finding in question is a notebook, clearly written in Fermi's handwriting, which records the frenzied days and nights that Fermi spent experimenting alone, driven by his theoretical ideas on beta decay. The notebook was found by the authors while browsing through documents left by Oscar D'Agostino, the chemist (...) among Fermi's group. From Fermi's notes, they reconstruct with skill and expertise the detailed timeline of the critical days leading up to his vital discovery. While much is already known about the road that led Fermi to his important result, this is the first time that it has been possible to reconstruct precisely when and how the initial evidence of neutron-induced decay was obtained. In relating this fascinating story, the book will be of great interest not only to those with a passion for the history of science but also to a wider audience. (shrink)

Theme 1 pertains to "importance." By ‘most important’ I mean most important to human beings. Physicists have generally shied away from the problems of human beings, and the role of our minds in nature, because they are so complex: these problems have been set aside for a later time. But that time has now arrived. The needed technologies, funding, and interest are all at hand. Moreover, the advances in technology now allow scores of laboratories to participate, and the number will (...) soon grow to hundreds: the data will come from many diverse sources, not just a few billion dollar facilities.

This paper proposes a novel conception of mental files, aimed at addressing Frege puzzles. Classical Frege puzzles involve ignorance and discovery of identity. These may be addressed by accounting for a more basic way for identity to figure in thought—the treatment of beliefs by the believer as being about the same thing. This manifests itself in rational inferences that presuppose the identity of what the beliefs are about. Mental files help to provide a functional characterization of a mind capable (...) of this presupposition, but more must be said to show how it may be rational. I argue that this can be done by drawing out the way in which mental files interact with a thinker's motivational states and so come to have normative functional properties. I show how this theory works better than some other treatments of mental files. (shrink)

God, Revelation and Authority by Carl Henry is one of the most important evangelical theological works of the twentieth century. Published between 1976 and 1983, it shaped the evangelical movement in countless ways and is still widely read, studied, and appreciated as a clear statement of evangelical beliefs contra liberalism and neo-orthodoxy. What you need to know is that God, Revelation and Authority is a key resource for understanding, teaching and defending many doctrines central to evangelicalism, including biblical inerrancy. It's (...) no accident that the list of endorsers for these books reads like a Who's Who of evangelical Christianity. If you want to have a better grasp of evangelical theology and its formation, there's no better place to begin than God, Revelation and Authority. Carl F. H. Henry was a central religious figure of the 20th century. In a 2004 article, Christianity Today stated that Carl Henry, along with Billy Graham and Boston pastor Harold John Ockenga, "practically invented what later became known as evangelicalism." He also helped found and served as the first editor for Christianity Today. God, Revelation and Authority is Henry's magnum opus. It contains the developed ideas of this prominent thinker on topics that include infallibility and inerrancy, divine revelation in nature, historical criticism, the Holy Spirit, the Church, and biblical history. It also includes the "Chicago Statement on Biblical Inerrancy" which for many years within evangelical circles has been an authoritative declaration regarding inerrancy. Later in life, Carl Henry spent a great deal of time considering the related concepts of religious knowledge and the doctrine of God. He concluded that, "if we humans say anything authentic about God, we can do so only on the basis of divine self-revelation; all other God-talk is conjectural." This basic premise underlies the entirety of God, Revelation and Authority. As you read God, Revelation and Authority you will see how many of the ideas in these six volumes have been enormously influential in shaping the beliefs and "distinctives" shared by evangelicals all over the world. - Publisher.

This paper focuses on two methodological questions that arise from Plato’s account of collection and division. First, what place does the method of collection and division occupy in Plato’s account of philosophical inquiry? Second, do collection and division in fact constitute a formal “method” (as most scholars assume) or are they simply informal techniques that the philosopher has in her toolkit for accomplishing different philosophical tasks? I argue that Plato sees collection and division as useful tools for achieving two distinct (...) goals – generating real definitions and discovering the basic natural kinds of a given domain of knowledge – both of which occupy a preliminary stage in his account of philosophical inquiry. As to the second question, I claim that the evidence for seeing collection and division as a formal method is weak. Although Plato calls the procedure a technê and a methodos, he makes no real attempt to formalize it in any way. For Plato, collection and division do not constitute an algorithmic process that can be learned from a rule book. Instead the ability to collect and divide properly are skills that good dialecticians must acquire through the kind of hands-on training illustrated by the Sophist and Statesman. Whereas Aristotle insists on formal rules for making proper divisions, Plato seems to emphasize the need to recognize where the natural joints of the world are. In this sense, Plato’s Sophist and Statesman and Aristotle’s Topics and Analytics present two very different pictures of collection and division. (shrink)

The model of the world proposed by Whitehead provides a natural theoretical framework in which to imbed quantum theory. This model accords with the ontological ideas of Heisenberg, and also with Einstein's view that physical theories should refer nominally to the objective physical situation, rather than our knowledge of that system. Whitehead imposed on his model the relativistic requirement that what happens in any given spacetime region be determined only by what has happened in its absolute past, i.e., in (...) the backward light-cone drawn from that region. This requirement must be modified, for it is inconsistent with the implications of quantum theory expressed by a generalized version of Bell's theorem. Revamping the causal spacetime structure of the Whitehead-Heisenberg ontology to bring it into accord with the generalized Bell's theorem creates the possibility of a nonlocal causal covariant theory that accords with the statistical prediction of quantum theory.

Quantum approaches to consciousness are sometimes said to be motivated simply by the idea that quantum theory is a mystery and consciousness is a mystery, so perhaps the two are related. That opinion betrays a profound misunderstanding of the nature of quantum mechanics, which consists fundamentally of a pragmatic scientific solution to the problem of the connection between mind and matter.

It is argued that an adequate scientific treatment of biological systems requires the use of an ontological interpretation of quantum mechanics, and that the propensity interpretation proposed by Popper and others, when applied to the brain, leads to a natural representation of conscious process within the quantum-mechanical description of brain process. Thus quantum mechanics, unlike classical mechanics, has a natural place for consciousness and, moreover, in a sense to be discussed, even requires it.

A well-known ambiguity in the term ‘argument’ is that of argument as an inferential structure and argument as a kind of dialogue. In the first sense, an argument is a structure with a conclusion supported by one or more grounds, which may or may not be supported by further grounds. Rules for the construction and criteria for the quality of arguments in this sense are a matter of logic. In the second sense, arguments have been studied as a form of (...) dialogical interaction, in which human or artificial agents aim to resolve a conflict of opinion by verbal means. Rules for conducting such dialogues and criteria for their quality are part of dialogue theory. Usually, formal accounts of argumentation dialogues in logic and artificial intelligence presuppose an argument-based logic. That is, the ways in which dialogue participants support and attack claims are modelled as the construction of explicit arguments and counterarguments (in the inferential sense). However, in this paper formal models of argumentation dialogues are discussed that do not presuppose arguments as inferential structures. The motivation for such models is that there are forms of inference that are not most naturally cast in the form of arguments (such as abduction, statistical reasoning and coherence-based reasoning) but that can still be the subject of argumentative dialogue. Some recent work in artificial intelligence is discussed which embeds non-argumentative inference in an argumentative dialogue system, and some general observations are drawn from this discussion.

This previously unpublished text of Michel Henry’s was written during the preparation of his first major work published in 1963: The Essence of Manifestation. Being devoted to the philosophy of Immanuel Kant, this extensive text could be as well integrated in the above mentioned book, namely in the context where the author criticizes the ontological monism privileged by the strong tradition of German philosophy, from Jacob Boehme and Kant to Heidegger. Starting from the topic of self-knowledge, this text focuses on (...) an internal division of Being, namely on the separation between consciousness and existence, an opposition that will take the form of a phenomenological distance. The author argues thus that the above mentioned German philosophical tradition is not able to grasp in its primordial nature the essence of the self, covered by the representation. (shrink)

William James has traditionally been seen as a critic of evidentialism, with his claim that “Our passional nature not only lawfully may, but must, decide an option between propositions, whenever it is a genuine option that cannot by its nature be decided on intellectual grounds” being understood as saying that in certain cases we have the right to believe beyond what is certified by the evidence. However, there is an alternate, “expansive”, reading of James (defended most recently by Cheryl Misak, (...) Robert Talisse, and Scott Aikin) that portrays him not as criticizing evidentialism itself, but only as trying to expand our conception what we should count as evidence. There are two main strategies for defending this ‘expansive’ reading. The first approach relies on showing that the logic of James’s argument itself relies on highlighting a new type of evidence rather than rather than undermining the need for our beliefs to be grounded in evidence, while the second approach appeals to aspects of James’s biography to show that he always intended something closer to the expansive reading. It is argued here that neither approach is persuasive, and that the anti-evidentialist reading of James remains the most probable. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 27.1 (2003) 231-240 [Access article in PDF] Rescuing the Rescuers in Philip Hallie's Ethical Sublime Patrick Henry "Only stories or visions of transcending personal isolation and indifference can move me... hope, joy lie only in the transcendence of self-absorption—in expansion." —Philip Hallie I THROUGHOUT HIS LIFE, Philip Hallie expressed strong distrust for abstract philosophy. He wanted his own philosophy constituted of flesh and blood, and he (...) believed in the centrality of narration in ethical writing. The personality of stories, the irrefutable nature of the individual's account had to form the essential basis in the teaching of ethics. It is no surprise, then, that in his posthumous Tales of Good and Evil, Help and Harm 1 Hallie leaves us with a series of powerful stories, biographical and autobiographical, as the final expression of his lifelong agonizing struggle to come to terms with his own ethical beliefs. There are no general proofs here. No abstract principles. No definitions of goodness and evil. Only stories that depict the being referred to by e. e. cummings as "manunkind" mysteriously achieving the "realizable ideal" of rescuer of strangers.Given Hallie's major work on the rescuers of Jews in the village of Le Chambon-sur-Lignon, Lest Innocent Blood Be Shed. The Story of the Village of Le Chambon and How Goodness Happened There, 2 it seems appropriate that he begin this particular account of "tales of good and evil" in that same [End Page 231] village. Thus, the first biography he presents is that of Magda Trocmé, the wife of the pastor of the Protestant Church in Le Chambon-sur-Lignon, André Trocmé, who, with his fellow pastor Edouard Theis, is said to have inspired the rescue mission in the village. Hallie underscores the communal nonviolent effort by clergy and villagers alike in this "city of refuge." While he admires both André and Magda as practitioners of the "great virtues," he more readily identifies with Magda's secularism than with her husband's piety. He celebrates her generosity, her refusal to turn anyone away from her door, her "quiet habit of efficacious compassion," and her terse explanation as to why the rescuers in the village did what they had done: "What do you mean? It had to be done, that's all."As much as Hallie related to Magda's secularism, he was unable to identify fully with her because he felt tainted by the killing he had done as an artillery man in the United States Army during World War II. "I was a helpful killer who violated the negative demand against killing ["Thou shalt not kill"] in order to obey the positive one to spread life. But Magda and her villagers! Their ethical purity was beyond me. They obeyed the negative demands of ethics by hating and hurting no one even while they obeyed the positive demands of ethics by saving [thousands of refugees]." Compared to Magda and the villagers, Hallie clearly saw himself as someone operating in the grey zone.With the introduction of Joshua James and the community of Hull, Massachusetts, we ascend from Hallie's personal quagmire of moral ambiguity to the realm of the "ethical sublime." Here the author relates the story of James, whose mother and sister died at sea in 1837 when he was 11 years old, and who would go on to a career of life-saving activity on the Massachusetts coast. James founded the Life-Saving Rescue Service, an organization that evolved into the Coast Guard (or more specifically The Search and Rescue Service of the Coast Guard). He spent his entire life in Hull (1826-1902) and over the course of nearly sixty years saved hundreds of sailor's lives and tens of thousands of dollars worth of property.Many coastal villages around the world, Hallie explains, profited greatly from shipwrecks. Their cargoes and the stuff the ships were made of were highly valuable to the generally poor people who inhabited such villages. Yet the village of Hull, the smallest village in the state, having roughly... (shrink)

Community custom has played a limited but important role in the law of property. In addition to a few major historic examples such as mining camp rules and whaling, property law sometimes relies on community custom, for example in adverse possession, nuisance law, and beach access. This Article proposes an informational theory of custom in property law. Custom is subject to a communicative tradeoff in the law: all else being equal, informationally demanding customs require an audience with a high degree (...) of common knowledge. General customs already known throughout society do not require much extra publicity from the law, and the law can easily draw on such customs. By contrast, customs that vary by community raise the question of the need for processing by non-expert audiences, i.e., outgroup dutyholders and government officials. This tradeoff helps explain the differential receptiveness to various customs and the process by which they are formalized if they are adopted into the law. The information-cost theory suggests that enthusiasts and skeptics of custom have both tended to ignore this process. The theory is then applied to some suggestive evidence from grazing customs and the pedis possessio doctrine in mining law, under which miners have pre-discovery rights to the spot being worked. Finally, the information-cost theory of custom sheds some light on the history and controversies over the numerus clausus and on the question of baselines of property entitlements in the law of takings.

This work, edited by Henry Rosemount, Jr, is Volume I in the series of "Critics and Their Critics". Angus C. Graham is the leading translator and interpreter of Chinese philosophical texts; he has written philosophical works of his own, he has written at length and in detail on early Chinese grammar and philology, he has translated Chinese poetry, and he has published some of his own poetry. Graham's polymathic achievement explains the polygenous nature of his collection, which has some essays (...) ranging broadly over aesthetics, ethics, religion, and epistemology; others providing concentrated discussion of specific problems in early Chinese syntax, semantics, etymology, and paleography; and yet others being admixtures, moving by turns through etymology, epistemology, and problems of the translation, interpretation, and dating of Chinese texts.

Before WW2 Danish geologists had found traces of uranium in Greenland. But being squeezed from both sides in the escalating Cold War between East and West, in the first decade after WW2 the Danish government did not support expeditions to explore Greenland's potential uranium deposits. The situation changed abruptly after President Eisenhower's Atoms for Peace address in December 1953, as a result of which a Danish Atomic Energy Commission (AEK) was set up in early 1955. Besides building a large atomic (...) energy research facility (Risø) one of AEK's first initiatives was to support big scale uranium expeditions to South-West Greenland. The ultimate goal for the leaders of AEK was to liberate Denmark from its dependence on imported fossil fuels by developing Danish nuclear reactors, fuelled by natural uranium from Greenland. In the late 1960s, after more than a decade of uranium explorations, this was still a goal, albeit much more long term. For many reasons the hunt for uranium in Greenland after WW2 was unsuccessful, but the main ones were Danish sovereignty concerns, techno-scientific nationalism and devastating institutional clashes of interests. The present paper will explore these problems. (shrink)

Coordination in thought is the treatment of beliefs by the believer as being about the same thing. Such treatment can be indirect, via an identity belief, or direct. Direct coordination presents a problem concerning how this treatment is justified. Dickie accounts for the justification of coordination in terms of aptness to a motivational state: coordination serves to fulfil a need to represent things outside the mind. I argue that this account gets the problem coordination presents wrong, and so does not (...) present an adequate solution. While the material of that account may be reconfigured to provide a more promising proposal, I argue that this depends on a specious psychology of belief, and will anyway end up being circular. I propose an account that, while similar in some ways, improves on both the official and reconfigured Dickie-style accounts, and points to some broader conclusions about the nature of rational cognition.

This paper outlines a code-theoretic approach to the substantive and pedagogical challenges created by the distinct interdisciplinary nature of the field of Africana Studies. It identifies some of the key discourse-constitutive codes and some strategies for suspending disciplinary boundaries created by these necessary codes, which should help us to navigate better the spaces between the disciplines engaged by Africana Studies. After examining these codes and methods for transcending them, the paper concludes with some pedagogical strategies for teaching these interdisciplinary aspects (...) of the field. (shrink)

The ArgumentIn this paper I show that in its original setting Boyle's New Experiments was not only rhetorical but also ideological. By employing a Lacanian theory of the subject, I show that this text not only disguised various “real contradictions“ in the fabric of Restoration society but also acted as a site for certain textual practices that played a role in the constitution of a new form of subjectivity for scientists. I also address the philosophical question of whether the ideological (...) and rhetorical nature of scientific texts impugns the status of their theoretical claims as paradigms of knowledge and rational belief.

The mainstream view today in neuroscience, biology, psychology, and philosophy, is that your conscious will has no effect upon your bodily actions beyond what is already caused by purely mechanical processes acting alone. Thus you are claimed to be, in essence, a mechanical automaton, with perhaps some elements of pure chance thrown in. Your natural belief that your willful efforts can have physical effects is called, accordingly, “The Illusion of Conscious Will”.

His words effectively assert, within a scientific context, that the mental realities that comprise a person’s stream of conscious experiences can influence the state of that person’s physically described body. That claim neither follows naturally from, nor meshes rationally with, the basic physical theory that, in 1799, had prevailed in science for more than a century---since the 1687 publication of Isaac Newton’s Principia---and that would continue to prevail for an additional century, until its replacement during the twentieth century by quantum (...) theory. It is this later theory that, according to the precepts of contemporary physics, must in principle be used to describe the dynamics of the ions and other microelements that underlies the brain processes associated with the mental realties. Unlike its predecessor, quantum mechanics was specifically designed to deal with the complex relationship between the empirical aspects of science represented in our sensory experiences and the physically described properties represented in our physical theories. This incorporation of the mental allows quantum theory to provide a rationally coherent understanding of influence mind upon body identified in the epigraph. The aim of this presentation is to describe this quantummechanical understanding to an audience of neurologists. (shrink)

This paper offers a caution that emphasis upon the importance of mathematics in recent historiography is in danger of obscuring the historical fact that, for the most part, mathematics was not seen as important in the pre-modern period. The paper proceeds by following a single case study, and in so doing offers the first account of the mathematical writings of Jean Fernel (1497–1558), better known as a leading medical innovator of the 16th century. After establishing Fernel's early commitment to mathematics, (...) and attempt to forge a career as a cosmographer, it goes on to explain his abandonment of mathematics for a career in medicine. The ‘mathematization of the world picture’ is usually explained in terms of the perceived usefulness of mathematics, but Fernel's case shows that for many pre-modern thinkers mathematics was not regarded as a useful pursuit. The paper should serve as a reminder, therefore, that the take-up of mathematics by natural philosophers was by no means inevitable, but had to be carefully managed by early modern mathematical practitioners. The case of Fernel indicates that perhaps he was not the only would-be mathematical practitioner to abandon mathematics in favour of a calling that was more appreciated by contemporaries. (shrink)

This model allows to study how the existence and structure of relations of epistemic trust in a group of truth-seeking agents might affect the epistemic performance of the agents taken individually and as a group. At each step, each agent independently receive from nature a noisy signal pointing to the real value of a certain parameter in [0,1], and balance this information with indirect information about the parameter he obtains by observing the beliefs of his trusted fellows. Agents are taken (...) to be boundedly rational and update their belief following a version of DeGroot model of update (also known as Lehrer-Wagner rule). The agents' abilities to extract information from nature can be differentiated between expert abilities and laymen abilities. These abilities can in turn be varied in the model, in the form of a variation of the standard deviation of the normal law followed by the random signals that experts and layman respectively receive from nature as indication pointing to the real value of the parameter. The structures of epistemic trust can be choosen amongst 4 possibilities : a so-called "master" structure, an "observer" structure, an "circle" structure and a form of random structure which can be used for control purposes in experiments. Epistemic performance is measured as the distance of the believed value to the true value of the parameter. (shrink)

Quantum theory has been formulated in several different ways. The original version was ‘Copenhagen’ quantum theory, which was formulated as a practical set of rules for making predictions about what we human observers would observe under certain well-defined sets of conditions. However, the human observers themselves were excluded from the system, in much the same way that Descartes excluded human beings from the part of the world governed by the natural physical laws. This exclusion of human beings from the (...) world governed by the physical laws is an awkward feature of Copenhagen quantum theory that is fixed by “Orthodox” quantum theory, which is the form devised by von Neumann and Wigner. This orthodox form treats the entire world as a quantum system, including the brains and bodies of human beings. Some more recent formulation of quantum theory seek to exclude from the theory all reference to the experiences of human observers, but I do not consider them, both because of their technical deficiencies, and because they are constitutionally unequipped to deal adequately with the causal efficacy of our conscious thoughts.1 The observer plays a central role in both Copenhagen and Orthodox quantum theory. In this connection, Bohr, describing the 1927 Solvay conference, noted that: “…an interesting discussion arose about how to speak of the appearance of phenomena for which only statistical predictions can be made. The question was whether, as to the occurrence of such individual events, we should adopt the.. (shrink)

. Lamarck and Darwin agreed on the inconstancy of species and on the exclusive gradualism of evolution. Darwinism, revived as neo-Darwinism, was almost generally accepted from about 1930 till 1960. In the sixties the evolutionary importance of selection has been called in question by the neutralists. The traditional conception of the gene is disarranged by recent molecular-biological findings. Owing to the increasing confusion about the concept of genotype, this concept is reconsidered. The idea of the genotype as a cluster of (...) genes is replaced by a cybernetical interpretation of the genotype. As nature does jump, exclusive gradualism is dismissed. Saltatory evolution is a natural phenomenon, provoked by a sudden collapse of the thresholds which resist against evolution. The fossil record and the taxonomic system call for a macromutational interpretation. As Lamarck and Darwin overlooked the resistance of evolutionary thresholds, an alternative evolution model is needed, the first to be constructed on a palaeontological and taxonomic basis. (shrink)
