Just because an angel is better than a stone, it does not follow that two angels are better than one angel and one stone. So said Aquinas (Summa contra Gentiles III, 71), and the sentiment was echoed by Leibniz. In section 118 of the Theodicy he wrote: "No substance is either absolutely precious or absolutely contemptible in the sight of God. It is certain that God attaches more importance to a man than to a lion, but I do not know (...) that we can bc sure that he prefers one man to an entire species of lions." Even Kant was bitten by this bug. In one of his pre-Critical works he was moved to say, à propos of lice, that even though they “may in our eyes be as worthless as you like, nevertheless it is of more consequence to Nature to conserve this species as a whole than to conserve a small number of members of a superior species." In these passages Aquinas, Leibniz, and Kant gave expression to a distinctive and interesting view about the value of animal species and animal populations. At its simplest, this is the view that there is a special value in the existence of animal species or in the existence of a wide variety of different animal species. But the view also goes deeper than this. An animal species, after all, is nothing over and above the individual animals which make it up, and the value which it contributes to the world must therefore be some function of the values contributed by those individual animals. At the deepest level, what the view expressed by Aquinas, Leibniz, and Kant holds is that the value which an individual animal contributes to thc world is not constant but varies with the number..

The purpose of our study is to demonstrate through an array of three themes that the role of the thought of Epicurus is central throughout the works of Friedrich Nietzsche. In doing so, we are going to study several themes among which the duality between the Apollonian and the Dionysian, the Übermensch and finally décadence (as the word is used in French by Nietzsche) and which Nietzsche associates to Epicurus in his last period. Our theoretical proposal consists of saying that (...) there is a common thread of the Epicurean thought in the Nietzschean works that makes it an important source of inspiration throughout his works in order to build some of his main concepts.

Current phenomenological approaches consider schizophrenia as a fundamental disturbance of the embodied self, or a disembodiment. This includes a weakening of the basic sense of self, a disruption of implicit bodily functioning, and a disconnection from the intercorporality with others. As a result of this disembodiment, the pre-reflective, practical immersion of the self in the shared world is lost. Instead, the relationship of self and world is in constant need of reconstruction by deliberate efforts, leading to the growing perplexity (...) and hyperreflexive ruminations that are found in schizophrenic patients. The paper distinguishes different levels of self-experience and relates it to the psychopathology of schizophrenia. (shrink)

We consider the Heisenberg uncertainty principle of position and momentum in 3-dimensional spaces of constant curvature K. The uncertainty of position is defined coordinate independent by the geodesic radius of spherical domains in which the particle is localized after a von Neumann–Lüders projection. By applying mathematical standard results from spectral analysis on manifolds, we obtain the largest lower bound of the momentum deviation in terms of the geodesic radius and K. For hyperbolic spaces, we also obtain a global lower (...) bound \, which is non-zero and independent of the uncertainty in position. Finally, the lower bound for the Schwarzschild radius of a static black hole is derived and given by \, where \ is the Planck length. (shrink)

The paper argues that the theory of Implicit Definition cannot give an account of knowledge of logical principles. According to this theory, the meanings of certain expressions are determined such that they make certain principles containing them true; this is supposed to explain our knowledge of the principles as derived from our knowledge of what the expressions mean. The paper argues that this explanation succeeds only if Implicit Definition can account for our understanding of the logical constants, and that fully (...) understanding a logical constant in turn requires the ability to apply it correctly in particular cases. It is shown, however, that Implicit Definition cannot account for this ability, even if it draws on introduction rules for the logical constants. In particular, Implicit Definition cannot account for our ability to apply negation in particular cases. Owing to constraints relating to the unique characterisation of logical constants, invoking the notion of rejection does not remedy the situation. Given its failure to explain knowledge of logic, the prospects of Implicit Definition to explain other kinds of a priori knowledge are even worse. (shrink)

Since, it has become clear that individuality is not to be considered as a given, but rather as something which needs to be explained. How has individuality emerged through evolution, and how has it subsequently been maintained? In particular, why is it that multicellular organisms appeared and persisted, despite the obvious interest of each cell of favoring its own replication? Several biologists see the immune system as one of the key components for explaining the maintenance of multicellular organisms’ individuality. Indeed, (...) the immune system exerts a constant surveillance on all the constituents of the organism, including “cheaters” like tumor cells, which favor their own replication at the expense of the whole organism. In most cases, the immune system eliminates those cheaters. This is the “immune surveillance” hypothesis, first suggested by Burnet and Thomas. In this paper, I account for recent findings on immune surveillance in order to determine the precise role of the immune system in the emergence and maintenance of individuality. This investigation gives rise to a critical question for the domain of biological individuality: should immunity be considered as something unique to multicellular organisms? If it is indeed unique, should the multicellular organism be considered as an individual to a higher degree than any other living entity? If it is not unique, what precisely are the equivalents of the immune system in other living individuals? (shrink)

Natural kinds have been a constant topic in philosophy throughout its history, but many issues pertaining to natural kinds still remain unresolved. This paper considers one of these issues: the epistemic role of natural kinds in scientific investigation. I begin by clarifying what is at stake for an individual scientific field when asking whether or not the field studies a natural kind. I use an example from life science, concerning how biologists explain the similar body shapes of fish and (...) cetaceans, to show that natural kinds play a central epistemic role in scientific explanations that cannot be delegated to other explanatory factors. A task for philosophy, then, is to come up with a theory of natural kinds that adequately accounts for the epistemic role of natural kinds in science. After having sketched the spectrum of available philosophical theories of natural kinds, I argue that none of the available theories adequately performs this task and that therefore the search is still open for a theory that does.

The phrase ‘The iterative conception of sets’ conjures up a picture of a particular settheoretic universe – the cumulative hierarchy – and the constant conjunction of phrasewith-picture is so reliable that people tend to think that the cumulative hierarchy is all there is to the iterative conception of sets: if you conceive sets iteratively, then the result is the cumulative hierarchy. In this paper, I shall be arguing that this is a mistake: the iterative conception of set is a (...) good one, for all the usual reasons. However, the cumulative hierarchy is merely one way among many of working out this conception, and arguments in favour of an iterative conception have been mistaken for arguments in favour of this one special instance of it. (This may be the point to get out of the way the observation that although philosophers of mathematics write of the iterative conception of set, what they really mean – in the terminology of modern computer science at least – is the recursive conception of sets. Nevertheless, having got that quibble off my chest, I shall continue to write of the iterative conception like everyone else.). (shrink)

As frequently pointed out in this discussion, one of the most characteristic features of Mayr's approach to the history of biology stems from the fact that he is dealing to a considerable degree with his own professional history. Furthermore, his main criterion for the selection of historical episodes is their relevance for modern biological theory. As W. F. Bynum and others have noted, the general impression of his reviewers is that “one of the towering figures of evolutionary biology has now (...) written a towering history of his discipline.”138 Bynum is here referring to The Growth of Biological Thought, but this observation holds equally true for Mayr's other historical writings: One must surely read this book [One Long Argument] not only for its content in itself, but for what it tells of its author. And certainly as one does so, one comes away full-handed. Many, if not all, of the disputes and controversies that have driven Mayr through his long intellectual life reappear, stated as forcefully and elegantly as ever.139Up to this point, most reviewers agree; the bone of contention is, rather, how to evaluate Mayr's historical work, considering this observation. The two related characteristics of his work-I will call them subjectivity and presentism-stand in opposition to a widespread approach in the history of science exemplified by Kuhn's suggestion that “insofar as possible..., the historian should set aside the science that he knows. His science should be learned from the textbooks and journals of the period he studies.”140 There are, however, historians who consider the close connection between Mayr and the subject matter of his historical studies to be an advantage.141On the other hand, it is assumed that the connection between past and present must result in a distortion of the historical truth and lead to a historiographical fallacy, commonly referred to as “Whig history”. Herbert Butterfield, who in 1931 gave the term its now generally accepted meaning, believed that “real historical understanding is not achieved by the subordination of the past to the present, but rather by our making the past our present and attempting to see life with the eyes of another century than our own”142. Unfortunately, Butterfield's definition of what he considers Whig history remains somewhat vague, and modern authors have emphasized what they consider most important. Butterfield's “subordination of the past to the present” is referred to in respect to the selection of subjects (there are more biographies of Charles Darwin than of, let's say, Louis Agassiz),143 to the evaluation of historical authors,144 or, more generally, to all kinds of histories “with one eye, so to speak, upon the present.”145 The underlying tendency of Whig historians is to produce a “historical account told from the viewpoint of those in power,”146 leading to a “glorification of the present.”147 It is obvious that Mayr's strongly presentist approach to the history of biology can be called Whiggish, if we apply the criteria of “selection” or “reference.” However, it might be worth mentioning that the program of writing a strictly historicist account of the history of science is challenged by various authors.148 For Mayr, it is not only legitimate but necessary to compare the present situation with the past. “Whiggish” is only the evaluation of an author in terms of our time.149I cannot discuss the Whit/anti-Whig controversy in any detail here, apart from saying that Mayr has defended himself rather extensively against the charges of being Whiggish.150 Nevertheless, it may be useful to touch on some of the criticisms that are predominant in reviews of his writings. First, we encounter the notion that historians can write a true and convincing historical account only if they have no personal interest or interpretation of their own; Mayr, on the other hand, because he “has such strong interpretations of his own, ... cannot possibly convince everyone that he is right about everything.”151 It makes one wonder, what historian has ever been able to convince everyone that he or she is right about everything? But apart from this peculiar idea, it unquestionably poses certain dangers if the subject matter of historical scrutiny and the author are identical. At the same time, this identity brings certain advantages with it, especially firsthand experiences of the period in discussion. Whether these personal memories ultimately result in a distorted picture of the past has to be decided in every particular instance. The notion that a scientific study can be conducted by a completely detached observer from a neutral standpoint has been shown to be impossible in physics, and it is also an illusion in historiography. The question is not whether, but which kind of interest are the underlying motivation for a historian. At this point, Mayr is ahead of his critics when he suggests that our understanding of the past always has a subjective component: The main reason, however, why histories are in constant need of revision is that at any given time they merely reflect the present state of understanding; they depend on how the author interpreted the current zeitgeist of biology and on his own conceptual framework and background. Thus, by necessity the writing of history is subjective and ephemeral.152Second, the temporal proximity between the event and the historical analysis makes difficulties inevitable and will finally result in certain false assessments. But this applies to all historians when they discuss recent problems, regardless of whether they are personally involved or not: As long as the battle between Darwinism and Lamarckism was raging, it was quite impossible to undertake an unbiased evaluation of Lamarck. ...[The] definite refutation of Lamarck's theory of evolutionary causation clears the air. We can now study him without bias and emotion and give him the attention that this major figure in the history of biology clearly deserves.153Third, Mayr is primarily interested in biological problems and not, for instance, historiographical, sociological, or psychological questions. Several authors have remarked that since the beginning of the professionalization of the history of science in the 1960s, a rift between two groups has developed, resulting from the heterogeneous professional backgrounds and interests of the people involved: the authors who were originally biologists and became interested in the history of their discipline only later on, and the authors who were trained as historians.154 Whereas the first group, the “biologists,” tend to be laymen in history proper, the “historians” are in most cases laymen in biology. Different professional backgrounds obviously shape the historical perspective in both groups, but neither approach is necessarily superior. The great number of important books in the history of biology written by “biologist” documents how valuable this point of view can be. On the other hand, it cannot be denied that the writings of biologists in the history of science tend to have a strong “internalist” tendency and often neglect the professional, cultural, and political context of science. Mayr's approach is that of a “biologist”; it is “internalist,” and typical for scientists who turn to the history of their discipline.I want to conclude my analysis with a quotation from a review by Douglas J. Futuyma, which gives a perceptive glimpse of Mayr's personality and style: One cannot help standing in awe of the germanic capacity for vast, allembracing synthesis: consider the lifelong devotion of Goethe to Faust, or Wagner's integration of the arts into a Gesamtkunstwerk in which all of human history and experience is wrought into epic myth. It is perhaps in this tradition that Ernst Mayr's The Growth of Biological Thought stands: a history of all of biology, a Ring des Nibelungen complete with leitmotivs such as the failures of reductionism, the struggle of biology for independence from physics, and the liberation of population thinking from the bounds of essentialism.155 Within this style of thinking Mayr has “to offer...nothing less than a vision of biology that places neodarwinian evolutionary theory firmly at the centre.”156 There may be other visions of biology, but few of them have as indefatigable and able representatives as Darwinism has in Ernst Mayr.

The question of how to demarcate science from pseudo-science commands relatively little attention today. In the philosophy of logic, by contrast, the problem of demarcating the logical constants is less skeptically regarded. In aesthetics, where the problem is how to demarcate art from non-art, the question as to whether the problem is a real one or a pseudo-problem also continues to be debated. This paper discusses the hypothesis that the demarcation questions in these three areas are parallel, or at least (...) similar enough to be interesting. Some arguments for the conclusion that the demarcation problem is a pseudo-problem are considered, as are some demarcation proposals of a deflationist or minimalist sort. All are found wanting.

Still, some may still want to say it. If so, my replies may gain nothing better than a stalemate against such persistence, though I can hope that earlier revelations will discourage others from persisting. But two replies are possible. Both come down, one circuitously, to an issue with us from the beginning: whether the language of the right side of (10) is suspect. For if (10) is to support instances for (6) which are about objects, that clause must itself be (...) about objects. (These would be ones assigned by variants of I it mentions to constants it mentions.) Yet Barwise and I would call it implicitly about functions. Ironically, the discussion surrounding (10), hoping to settle that issue, could only do so if the issue were already settled, revealing decisively the ontology of (10). If irritating, this is also inevitable, given the Tarskian spirit of the ensivioned semantics for QLB.A second reply begins by noting that a QLB semantics which implies (10) cannot simply be assumed. Even a QL semantics augmented to imply (11) is not trivial to frame, as I will let readers confirm. On the QLB project, Barwise comments thus:It is not possible to explain the meaning of an essential use of branching quantification ... inductively, by treating one quantifier at a time in a first-order fashion. Some use of higher-type abstract objects is essential. (BQE75)But believers in a modest ontology for QLB can claim a non sequitur here. For (10), as they read it, succeeds without mentioning abstract objects, though not in the “one quantifier at a time” way which Barwise rightly finds impossible. This is not yet to say the same about a QLB semantics implying (10). But that too can be said, as it happens, with as good a conscience as with (10). A suitable treatment can begin by somehow linearizing non QL sentences like (6). Still assuming prefixes whose rows each consist, speaking loosely, of n universal quantifiers followed by a single existential, we could simply line up these rows in any order, with unique deconcatenatability being assured. From then on, it gets both tedious and complex. A full syntax is essential, and some surprising categories arose in mine. I will spare readers all details, except to say that one can indeed “treat one quantifier at a time”, if not “in first-order fashion”: schematic rules for treating n quantifiers at once can be eschewed. Unsurprisingly, heavy use is made of the “depending only on” idiom seen in (10). Nor does it surprise me that this semantics can succeed, with that idiom available. Roughly, if open talk about functions works in a semantics for QLF, what I read as implicit talk about them should work in a semantics for QLB See [6] for a start on a semantics aspiring to handle sentences like (6) without invoking abstract objects. See also my comments on its notion of dependence, in [9]. . So even from a bare sketch, we can see that this new semantics settles nothing. It just leads back to the stalemate. Barwise and I will read crucial clauses as talking implicitly about functions, but this general charge against an idiom is equally deniable wherever the idiom occurs: in a reading for (6), say, or in the metalanguage can hardly repress a motherhood slogan: better dead than obscurely read. But that just denies the denial, unhelpfully. A better comment is the reminder that the claim stays alive only in a form which no one has ever imagined for it. The QLB quantifiers that cannot be shown not to range over objects are not the items anyone would ever have pointed to in illustrating the unkillable claim. (shrink)

Modelling of contagious disease usually employs compartmental SEIR-like models where the waiting times in respective compartments are exponentially distributed. In this paper, we are interested in investigating how the distributions of sojourn times in infective compartments affect the dynamics and persistence of the contagious bovine pleuropneumonia, a chronic respiratory disease of cattle. Two kinds of extreme distributions of the sojourn times are considered: a Dirac delta-function and truncated Gaussian function leading to a model with (non-constant) delay and the classical (...) exponential distribution that stands for a model without delay. Expressions of the basic reproductive numbers are derived and dynamical behaviours are discussed for the three models. It is found that the spreading of disease exhibits wave-like oscillations for the time-delay dynamics. In contrast, the disease appears to last longer when the spreading is described by the classical dynamics without delay. Subsequently, the time-delay dynamics turns out to be more appropriate for the description of an experimental epidemic of CBPP. (shrink)

Tina Beattie has re‐read Aquinas in the light of Lacanian theory and found the later Lacan's transition to what he calls the register of “the Real” to be significant for a revitalised theology beyond traditional intellectual categories. She argues for a maternal Trinity which she believes to lie hidden in Thomas and, in support of this, she contends that Lacan left behind Freud's paternal preoccupations in favour of maternity. This response to Beattie will re‐examine Lacan's trajectory from “the Symbolic” (...) register to “the Real” through the lens of what he said in his year‐long seminars about Moses, whom he regarded as a representative of “the Symbolic”, and it will demonstrate that paternity remained a constant in Lacan, who even came to see “the Real” itself as a name of the father.

This thesis is about the metaphysics of logic. I argue against a view I refer to as ‘logical realism’. This is the view that the logical constants represent a particular kind of metaphysical structure, which I dub ‘logico-metaphysical structure’. I argue instead for a more metaphysically lightweight view of logic which I dub ‘logical expressivism’. -/- In the first part of this thesis (Chapters I and II) I argue against a number of arguments that Theodore Sider has given for logical (...) realism. In Chapter I, I present an argument of his to the effect that logico-metaphysical structure provides the only good explanation of the semantic determinacy of the logical constants. I argue that other explanations are possible. In Chapter II, I present another argument of his to the effect that logico-metaphysical structure is something that comes along with ontological realism: the view that there is a non-language-relative fact of the matter about what exists. I argue that the connection between logical and ontological realism is not as close as Sider makes it out to be. -/- In the second part of this thesis (Chapters III – V) I set out a positive view of the logical constants that can explain both why their meanings are semantically determinate, and why they form part of our vocabulary. On that view, the primary bearers of logical structure are propositional attitudes, and the logical constants are in our language as vehicles for the expression of logically complex propositional attitudes. In Chapter III, I set out an expressivist theory of propositional logic. In Chapter IV, I use this theory to explain how the logical connectives end up having determinate meanings. In Chapter V, I extend the expressivist theory to predicate logic. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Thomas G. Pavel INCOMPLETE WORLDS, RITUAL EMOTIONS' IN recent years, the notion of "fictional world" has enjoyed a considerable rise in fortune. The expression, however, is not entirely new. To refer to the world of a literary work, of a novel or of a play, has always been a favorite way of speaking for literary critics and aestheticians. In most cases, these were informal worlds. A discussion of (...) the world of Balzac, Dostoyevsky, HenryJames, or Proust often amounts to a description of each author's preferences in die selection and rearrangement of his material. Such discussion primarily fits authors who purposefully attempt to build comprehensive representational artifacts. One speaks quite naturally about l'univers balzacien, or about the universe of Musil. But is one entitled to refer with equal ease to the world ofBenjamin Constant, meagerly perceptible in his Adolphe, a short novel built in the spirit of economy, displaying just a few characters and a minimum of worldly information? Perhaps density and comprehensiveness are not indispensable characteristics of literary worlds. Aestheticians and narratologists using the "fictional worlds" terminology seem to believe mat any kind of artistic text projects a world, be it rich or poor. Such worlds are imagined in the fashion of modern philosophy of logic as states of affairs, more or less comprehensive. Some writers believe that the states of affairs comprised in fictional worlds must be fairly sizable, since diey should include "not only what the author indicates, but also whatever is required (entailed) by that which he indicates." 1 The laws of nature which are not specifically contradicted by the text would belong to its world. Thus, a few notorious cases aside, there is no reason to doubt that every child born in fiction has been engendered by a human fadier as long as the text does not report an exception. And if it does? Then, assuming that the laws of logic still govern if not fiction itself at least our understanding of it, we may appeal to what "possible world" philosophers have called "small miracles." * Editor's note: This article, as well as the contributions by Gerald Prince, Peter van Inwagen, and Kendall Walton which follow it, grew out ofa symposium on "Styles ofFictionality," organized by Professor Pavel and held at Harvard University in 1981. The Fall, 1983 issue of PHILOSOPHY AND LITERATURE will contain additional papers presented at the symposium. 48 Thomas G. Pavel49 Imagine, for instance, the world in which Notre Dame de Paris would be covered with blue paint. While everything else would preserve the properties it possesses in the actual world, with the laws of nature and the caused chains maintained, a small local change, somewhat miraculous, would modify only the color of the venerable building. Similarly, the world of Balzac may be understood as the world of early and mid-nineteenth-century France, slightly modified by the addition of a few hundred imagined characters. That diese conform surprisingly well to the general laws of French society of the time is so much the goal of Balzac's successful project, that for the sociologically-minded reader die' actual nonexistence of Rastignac, Rubempré, Vautrin, or Birotteau may appear a mere accident. These characters, one may surmise, display every trait that actual counterparts of theirs would possess, except existence. Hence, why would Rastignac's or Vautrin's emergence in a world omerwise identical to nineteenth-century France amount to anydiing more than a "small miracle"? On the other hand, Balzac's world being blessed wim hundreds of such miracles, the very magnitude of the project vindicates the attribute of "visionary," ascribed to Balzac by Béguin, or, if metaphorically undercut, mat of"God the Father" given him by Thibaudet. For, would not such magnitude entail more than just local changes in an otherwise faithful representation of the "actual" nineteenthcentury France? Similarly, would we interpret a fictional world in which a child has been engendered not by a human father, but by a divinity, as identical in all respects to the actual world, except for the limited modification attributed to a small miracle? 2 If we grant for a moment the improbable assumption that nineteenth-century France was a given and that Balzac...

Some terms identify enigmata of today’s cosmology: “Inflation” is expected to explain the homogeneity and isotropy of the cosmic background. The repulsive force of a “dark energy” shall prevent a re-collapse of the cosmos. The additional gravitational effect of a “dark matter” was originally supposed to explain the deviations of the rotation curves of the galaxies from Kepler’s laws. Adopting a theory founded on the core notion of absolute quantum information–Protyposis–being a cosmological concept from the outset, the observed phenomena can (...) be explained without postulating further unknown specific “particles” or “fields”. Moreover, this theory allows for a rationalization of the fact that huge black holes with their enormous jet structures, acting as “seeds” of the galaxies, are detected ever closer to the big bang. The problem of the rotation curves in the galaxies can be addressed outside of General Relativity within a Newtonian approximation: by an attenuation of the gravitational acceleration as in the modified Newtonian dynamics, or by the effect of additional invisible “particles of dark matter”, yet unknown and not yet established in natural sciences. Within the Protyposis theory, these problems are solved without having to invent a lot of parameters. The cosmology of the Protyposis causes the change of the gravitational acceleration in the vicinity of large masses and, at the same time, avoids a recollapse of the cosmos for which a cosmological constant or “dark energy” was invented.

In The Sublime Object of Ideology, Slavoj Žižek tells a story about Buddhist prayer wheels in Tibet as a model of secularization: a belief machine. When routine actions are being performed, the animating principles or belief are no longer foregrounded in the process. While the developers of the scientific method were mostly devout Christians and believed in God’s direct involvement in the affairs of earth, carefully repeating situations through controlled experiments convinced them any potential variance in the processes they investigated (...) could be ignored. Applied generally, through the process of secularization, religious acts are automated so that people can go about their business without requiring constant awareness of God’s presence. While the foundations of science and innovations in healthcare have many connections with religion, the professionalization of medicine acts as a superstructure supporting the belief. A Christian hospital today is like a prayer flag in the wind: operating automatically through set policies but actualizing theology through its repetition of care. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:T. S. Eliot, Dharma Bum:Buddhist Lessons in The Waste LandThomas Michael LeCarnerMany critics have argued that T. S. Eliot's The Waste Land is a poem that attempts to deal with the physical destruction and human atrocities of the First World War, or that he had somehow expressed the disillusionment of a generation. For Eliot, such a characterization was too reductive. He replied, "Nonsense, I may have expressed for them (...) their own illusion of being disillusioned, but that did not form part of my intention." He did not want to be the poet of a "lost generation" of war survivors, but rather, he wanted, like most poets, to write for all ages. To that end, Eliot sought to transcend time and space by bringing to The Waste Land scores of literary, cultural, and artistic allusions from a variety of sources including the Upanishads, Greek mythology, the Bible, Chaucer, Dante, Spenser, Shakespeare, and Leonardo Da Vinci. Ironically, within this menagerie of literary homages, Eliot has created a vast emptiness, a world of pain, suffering, desolation and despair, as if to suggest that even in the presence of all the greatest artistic and cultural achievements of mankind, we must understand that life is transitory and material things ephemeral.The idea that life is fleeting and filled with suffering is at the core of Buddhist thought and one that Eliot surely learned from his graduate studies at Harvard. Several scholars have examined the influence of Eastern philosophy, and in particular Buddhist thought, on Eliot's work, largely in the past forty years.1 My argument departs from this scholarship in two significant ways. First, I will read The Waste Land through the lens of Eliot's graduate studies, and in doing so will show how the poem functions as a didactic, artistic representation of the Buddhist doctrine of samsāra, an idea that views the world as transitory, overcome [End Page 402] with lustful desires, and forever bound to a cycle of life, death, and rebirth. From this perspective, we can see how Eliot's understanding of the original Buddhist texts, which informed much of his writing of The Waste Land, allowed him to see through the all-too-common misconceptions about Buddhism during the early part of the twentieth century. Lastly, we will see that Eliot looked at these misconceptions as a psychological projection of Europeans' discontent with their own lives in an uncertain time.Over the past three decades an increasing number of scholars have studied Eliot's graduate work. In 1985, Jeffrey Perl and Andrew Tuck published a study that examines the impact that Eliot's coursework and professors had on during his studies at Harvard.2 Perl and Tuck point out that Eliot devoted nearly one third of his graduate program to the study of Asian philosophy and philology. Eliot studied Sanskrit and Pali under C. R. Lanman, the preeminent Sanskrit specialist of the age. In his third year, Eliot took a course entitled "Schools of Religious and Philosophical Thought in Japan" with Professor Masaharu Anesaki, a course that had a profound impact on him. Eliot was exposed to several schools of Buddhism in his studies including the Kegon, Shingon, and Tendai, which are characterized as "descendants of the Madhyamika School, which was founded in the second century A.D. by Nāgārjuna, the Indian Buddhist philosopher." Nāgārjuna is widely considered the most influential Buddhist philosopher after Siddhartha Gautama himself and is the leading proponent of the Mādhyamika ("Middle Way") philosophy.The central teaching of Nāgārjuna was the doctrine of śūnyatā, or as it is often translated, "emptiness." For Mahāyāha Buddhists, all things are totally empty of any defining essence. Thus, all things are void of any fixed identity or inherent existence and remain in a constant state of impermanence, change, and flux. This is the fundamental premise of Mahāyāha Buddhism. Only through the realization of this emptiness in material things can one achieve Buddhahood. According to one standard text, "the real knowledge of Buddha nature is empty of empirical content, and it is the discovery of that emptiness or void, śūnyatā, of the true Buddha... (shrink)

Since ancient times philosophy has dealt with the relation between technology and man. Nowadays this is especially true in the context of the philosophy of technology. Technology is interpreted as an anthropological constant to construct an environment in which man can survive. Acting in the field of technology is to act rationally with a purpose, i.e., in the framework of a means-end relation, and it is employed for coping with experiences (Widerfahrnisse) by means of using tools. Like technology, language (...) can be reconstructed as a symbolic form and thus as a technological means, as a tool so that the employment of metaphors can also be described as an employment of tools. Using technology has effects on man as well as on his self-image. Thus, philosophy of technology creates different ideas of man, which have to become subject to ethical discourses. (shrink)

A diploid human genome contains approximately six billion nucleotides. This enormous amount of genetic information can be replicated with great accuracy in only a few hours. However, because DNA strands are oriented antiparallel while DNA polymerization only occurs in the 5′ → 3′ direction, semi‐conservative replication of double‐stranded DNA is an asymmetric process, i.e., there is a leading and a lagging strand. This provides a considerable opportunity for non‐random error rates, because the architecture of the two strands as well as (...) the DNA polymerases that replicate them may be different. In addition, the proteins that start or finish chains may well be different from those that perform the bulk of chain elongation. Furthermore, while replication fidelity depends on the absolute and relative concentrations of the four deoxyribonucleotide precursors, these are not equal in vivo, not constant throughout the cell cycle, and not necessarily equivalent in all cell types. Finally, the fidelity of DNA synthesis is sequence‐dependent and the eukaryotic nuclear genome is a heterogeneous substrate. It contains repetitive and non‐repetitive sequences and can actually be considered as two subgenomes that differ in nucleotide composition and gene content and that replicate at different times. The effects that each of these asymmetries may have on error rates during replication of the eukaryotic genome are discussed. (shrink)

Comment combattre la langue de bois ? Ce devrait être la première préoccupation des commentateurs politiques, chargés de commenter, d’analyser et d’éditorialiser. Mais, comme celle des hommes politiques, la langue de bois des commentateurs a pour objectif principal de ne pas tout dire. Elle est faite pour leur permettre de s’adresser au plus grand nombre, sans choquer, souvent même en délivrant à l’auditeur ou au lecteur une pensée dans laquelle il peut se reconnaître. Il existe aussi une autre sorte de (...) langue de bois, plus problématique dans les métiers de commentateurs : une langue de bois réflexe, faite de formules creuses, de poncifs et de métaphores . Par ailleurs, l’une des tendances les plus spectaculaires de ces dernières années est l’avènement de ce que l’on peut appeler le « parler cash », façon de rejeter la langue de bois. Une parole cash devient un acte politique en lui-même, un acte creux, et les journalistes en sont coresponsables puisque travaillant à jet continu avec Internet et les chaînes tout-info. En revanche, le numérique permet de conserver et de classer ce qui se dit. La mémoire politique s’est démocratisée et Internet met à la disposition de chacun l’ensemble des propos des hommes politiques. Cette évolution du rapport entre le discours et son commentaire est bienvenue après des décennies de consanguinité entre les politiques et les commentateurs.How do you fight doublespeak? This ought to be the main concern of every political commentator, whose job is to comment on, analyse and editorialise what politicians say. But, like politicians, commentators use a language whose main purpose is to not say everything. It is made for them to address the widest possible audience, without giving offence and often by offering listeners or readers thoughts they can recognise as their own. This sort of language also exists in another more problematical form among commentators, as a kind of reflexive newspeak made up of clichés, commonplaces and metaphors involving warfare, sports or cookery. One of the more spectacular trends in the last few years is the advent of what the French call « parler cash », meaning « rude straight talk », as an antidote to doublespeak. « Talking rude and straight » then becomes a political – and hollow – act in itself, for which journalists are equally responsible since they are constantly working live with the Internet and 24-hour news channels. On the other hand, everything that is said can now be stored and classified on digital media. The archives of politics are becoming available to all and anyone can use the Internet to access anything a politician has ever said. This is a welcome development for the relationship between discourse and commentary, after decades of blood relationships between politicians and political commentators. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:119. HUME'S CONDITIONS FOR' CAUSATION: FURTHER TO GRAY AND IMLAY As part of his second proof of the existence of God, Descartes in Meditations III argues a causal premise derived from the nature of time. He argues it follows from the nature of time "that, in order to be conserved in each moment in which it endures, a substance has need of the same power and action as would (...) be necessary to produce and create it anew, supposing it did not yet exist; so that the light of nature shows us clearly that the distinction between creation and conservation is solely a distinction of reason." The nature of time to which he refers allows only a finite divisibility into durationless moments, each of which is entirely independent of every other. In the ultimate analysis, nothing true of one moment is deducible from what is true of any other, even what happens to be eternally true. The doctrine of the creation of the eternal verities is of a piece with this conception of time, and following with it from the conception of the divinity as sheer omnipotence, points to Hume's view that experience is the only guide to the world. It would seem to be Descartes' view, that nothing at a given time can stand in the necessary relation it must have to be a cause of something at another time; or, only something outside time can be a cause, for whose operation things in time can serve as but occasions. To what extent this dialectic in fact led to later occasionalist views is an historical question we need not consider. My only suggestion here concerns Hume's réponse to the occasionalists. With all but psychological necessity eliminated from his analysis of causation, Hume effectively argues the familiar case that occasional causes are the only causes by arguing the finite divisibility of time. In the literature only Laporte has held that for Descartes time is infinitely divisible and in this sense continuous. The separability of the parts of time, he 120. thought, suffice for their independence and contingency. But if time is continuous, its parts are inseparable; as Gueroult correctly observes, by discontinuity is meant con2 tingence, independence and separability. In addition, if a moment had duration, light would not be propagated instant aneously, thus according to Descartes upsetting his entire 3 physics. Gueroult maintains, rather, that Descartes' view of time is determined by his view of motion. Whatever the historical and logical priorities, there clearly is a connection between the above and what Bergson called the cinematographic conception of motion as a succession of static objects. It is a conception that precludes events as such. Motion occurs only in time, never at the moment, and occurs as a result of the re-creation of matter with regularly differing spatial relations. Due to metaphysical consideration expressed in theological terms, especially with reference to the immutability and simplicity of divine ways, this recreation of matter is constrained in certain ways, some of which we pick out as conditions for what was later called occasional causation. Put very simply, only what is constantly conjoined can stand in this relation; and that there should be instances of constant conjunction follows from the metaphysical considerations. With Hume's elimination of these metaphysical considerations, the status of the conditions, which he takes over as conditions for causation simpliciter, becomes problematic. But a recent challenge to Hume's program is still more problematic. The contention is that there is a case in which Hume's conditions necessary fo constant conjunction cannot all be satisfied. Even worse, i is a case in which his analysis ought to be conspicuously successful, viz. collision, which Hume like Descartes con4 ceives in cinematographic terms.

The contemporary Spanish philosopher Xavier Zubiri developed his philosophy in constant dialogue with the past. Zubiri believed that there are fundamental flaws with classical philosophy that require a fresh approach. His critique of classical philosophy falls into three areas: conceptual, factual, and scope. The first is treated in this paper with respect to five subjects. Zubiri believed that the structure of human intellection is incorrect in classical philosophy. This error contributes in large part to two key errors which he (...) termed "entification of reality" and "logification of intellection." Closely related are errors concerning essence and the relationship of truth and reality. (shrink)

La guerre peut-elle être un objet de la philosophie? Si la réalité guerrière obsède les philosophes, elle leur oppose néanmoins une résistance permanente. En parcourant les représentations de la guerre produites de Platon à Clausewitz, et en mettant à nu les stratégies constantes et les impensés qui les sous-tendent, on constate que le philosophe n'a cessé de manquer un enjeu guerrier qu'il ne peut toucher qu'en le neutralisant. Quelques figures à la fois persistantes et exclues de ces philosophies de la (...) guerre - l'esclave, le pirate, le colonisé..., de même que des pratiques philosophiques restées plus marginales - la pensée romaine, le matérialisme machiavélien, la déconstruction..., permettent cependant de bousculer ce discours neutralisant et, ce faisant, de révéler une certaine compromission de la philosophie dans la guerre."--Page 4 of cover.

Based on the property of extensivity , we derive in a mathematically consistent manner the explicit expressions of the chemical potential μμ and the Clausius entropy S for the case of monoatomic ideal gases in open systems within phenomenological thermodynamics. Neither information theoretic nor quantum mechanical statistical concepts are invoked in this derivation. Considering a specific expression of the constant term of S, the derived entropy coincides with the Sackur–Tetrode entropy in the thermodynamic limit. We demonstrate, however, that the (...) former limit is not contained in the classical thermodynamic relations, implying that the usual resolutions of Gibbs paradox do not succeed in bridging the gap between the thermodynamics and statistical mechanics. We finally consider the volume of the phase space as an entropic measure, albeit, without invoking the thermodynamic limit to investigate its relation to the thermodynamic equation of state and observables.

We report three experiments investigating whether people’s judgments about causal relationships are sensitive to the robustness or stability of such relationships across a range of background circumstances. In Experiment 1, we demonstrate that people are more willing to endorse causal and explanatory claims based on stable (as opposed to unstable) relationships, even when the overall causal strength of the relationship is held constant. In Experiment 2, we show that this effect is not driven by a causal generalization’s actual scope (...) of application. In Experiment 3, we offer evidence that stable causal relationships may be seen as better guides to action. Collectively, these experiments document a previously underappreciated factor that shapes people’s causal reasoning: the stability of the causal relationship. (shrink)

This volume is the first ever collection devoted to the field of proof-theoretic semantics. Contributions address topics including the systematics of introduction and elimination rules and proofs of normalization, the categorial characterization of deductions, the relation between Heyting's and Gentzen's approaches to meaning, knowability paradoxes, proof-theoretic foundations of set theory, Dummett's justification of logical laws, Kreisel's theory of constructions, paradoxical reasoning, and the defence of model theory. The field of proof-theoretic semantics has existed for almost 50 years, but the term (...) itself was proposed by Schroeder-Heister in the 1980s. Proof-theoretic semantics explains the meaning of linguistic expressions in general and of logical constants in particular in terms of the notion of proof. This volume emerges from presentations at the Second International Conference on Proof-Theoretic Semantics in Tübingen in 2013, where contributing authors were asked to provide a self-contained description and analysis of a significant research question in this area. The contributions are representative of the field and should be of interest to logicians, philosophers, and mathematicians alike. (shrink)

Although most consumers are positive about socially responsible companies, in order to benefit from CSR efforts, effective and clear CSR communication is important. However, due to the constantly rising profusion of eco-labels, based on either own claims from the organization or claims made by an external third party, consumers may encounter difficulties in identifying truly responsible firms, which could result in less effective CSR initiatives, even for those responsible firms. Therefore, building on attribution theory, this study seeks to identify how (...) uncertified internal CSR claims and external third-party CSR labels should be used in order to deter greenwashing and increase positive consumer evaluations. Within a 3 (external third-party CSR label: positive vs. negative vs. no label) × 2 (uncertified internal CSR claim: present vs. absent) design, respondents are exposed to different coffee product packages measuring their attitude toward the brand, corporate credibility, purchase intention, and scent perception, as well as perceived attributional CSR motives. Overall, findings indicate that especially an external CSR label affects consumer responses toward the firm. Moreover, perceived CSR motives serve as a mediator between an external CSR label and corporate credibility and brand attitude, respectively. These findings warrant further consideration of introducing an external multilevel rating systems by governmental law. (shrink)

We give two social aggregation theorems under conditions of risk, one for constant population cases, the other an extension to variable populations. Intra and interpersonal welfare comparisons are encoded in a single ‘individual preorder’. The theorems give axioms that uniquely determine a social preorder in terms of this individual preorder. The social preorders described by these theorems have features that may be considered characteristic of Harsanyi-style utilitarianism, such as indifference to ex ante and ex post equality. However, the theorems (...) are also consistent with the rejection of all of the expected utility axioms, completeness, continuity, and independence, at both the individual and social levels. In that sense, expected utility is inessential to Harsanyi-style utilitarianism. In fact, the variable population theorem imposes only a mild constraint on the individual preorder, while the constant population theorem imposes no constraint at all. We then derive further results under the assumption of our basic axioms. First, the individual preorder satisfies the main expected utility axiom of strong independence if and only if the social preorder has a vector-valued expected total utility representation, covering Harsanyi’s utilitarian theorem as a special case. Second, stronger utilitarian-friendly assumptions, like Pareto or strong separability, are essentially equivalent to strong independence. Third, if the individual preorder satisfies a ‘local expected utility’ condition popular in non-expected utility theory, then the social preorder has a ‘local expected total utility’ representation. Fourth, a wide range of non-expected utility theories nevertheless lead to social preorders of outcomes that have been seen as canonically egalitarian, such as rank-dependent social preorders. Although our aggregation theorems are stated under conditions of risk, they are valid in more general frameworks for representing uncertainty or ambiguity. (shrink)

Justification logics are modal logics that include justifications for the agent's knowledge. So far, there are no decidability results available for justification logics with negative introspection. In this paper, we develop a novel model construction for such logics and show that justification logics with negative introspection are decidable for finite constant specifications.

This paper deals with: (i) the theory ID # 1 which results from $\widehat{\mathrm{ID}}_1$ by restricting induction on the natural numbers to formulas which are positive in the fixed point constants, (ii) the theory BON(μ) plus various forms of positive induction, and (iii) a subtheory of Peano arithmetic with ordinals in which induction on the natural numbers is restricted to formulas which are Σ in the ordinals. We show that these systems have proof-theoretic strength φω 0.

When infrastructural technology is functioning correctly, it is often considered to recede from view and become invisible. According to this perspective, visibility is restored in cases of breakdown and malfunction, which for this reason, are often understood to represent important epistemic opportunities for grasping previously hidden aspects of infrastructure. This article seeks to outline the limitations of the idea that infrastructural failure has a positive epistemic function by distinguishing between two fundamentally different ways in which the nature of technological function (...) can be conceptualised; the first understands function as stemming primarily from the way a technology was designed and produced, the second as a process sustained by constant human activities of maintenance and repair. After illustrating how a number of recent studies of infrastructure build upon insights granted by the latter process perspective, this article aims to demonstrate how the experience of breakdown itself does little to facilitate a shift towards understanding infrastructure in this way. For this reason, this article ends with a suggestion for a shift in emphasis in studies of infrastructure, away from breakdown and towards a sustained examination of everyday practices of maintenance, repair and modification of infrastructural technologies.

The first edition of the first volume of Jonas’ legendary Gnosis und spätantiker Geist appeared just over half a century ago. Since then, the publication of the second volume, which was to cover Philo, Origen, Plotinus, and Euagrius Ponticus, has been eagerly awaited. In 1954, the wait came to an end—at least partially. Immediately after the Second World War, which had violently interrupted Jonas’ work and forced him, a Jew, to leave Germany in 1933, he heard that the printing plates (...) of the second volume still existed. And though another ten years went by, the first part of that volume, From Mythology to Mystical Philosophy, eventually appeared covering Philo and Origen. The third edition appeared roughly ten years later in 1963 and was enhanced by a fourth chapter containing new material from the Nag-Hammadi Library, material which, as Jonas emphasized, confirmed the central thesis of the first edition in a surprising manner. But still the Plotinus chapter was missing. And especially this chapter was of interest to scholars of Neoplatonism, since Jonas’ main hypothesis that Plotinian thought also has to be included in the so-called Gnostic Age, seemed to contradict Plotinus’ express dissociation of himself from the Gnostics. Although Jonas was constantly concerned with that chapter, he did not find himself in a position to finish it. We thus have Kurt Rudolph to thank for his endeavor, with Jonas’ assistance, to prepare and arrange the missing chapter on the basis of Jonas’ other publications and also of still unpublished manuscripts, material which now constitutes chapters 6 and 7 in volume II. Jonas died unexpectedly on February 5, 1993, shortly before its publication, so that he could not witness this new, “complete,” and yet still fragmentary edition of his Gnosis and spätantiker Geist.

Karl Popper developed a theory of deductive logic in the late 1940s. In his approach, logic is a metalinguistic theory of deducibility relations that are based on certain purely structural rules. Logical constants are then characterized in terms of deducibility relations. Characterizations of this kind are also called inferential definitions by Popper. In this paper, we expound his theory and elaborate some of his ideas and results that in some cases were only sketched by him. Our focus is on Popper's (...) notion of duality, his theory of modalities, and his treatment of different kinds of negation. This allows us to show how his works on logic anticipate some later developments and discussions in philosophical logic, pertaining to trivializing connectives, the duality of logical constants, dual-intuitionistic logic, the conservativeness of language extensions, the existence of a bi-intuitionistic logic, the non-logicality of minimal negation, and to the problem of logicality in general.

Immanuel Kant defines virtue as a kind of strength and resoluteness of will to resist and overcome any obstacles that oppose fulfilling our moral duties. Human agents, according to Kant, owe it to ourselves to strive for perfect virtue by fully committing ourselves to morality and by developing the fortitude to maintain and execute this life-governing policy despite obstacles we may face. This essay reviews basic features of Kant’s conception of virtue and then discusses the role of emotions, a motive (...) of duty, exemplars, rules, and community in a virtuous life. Kant thinks that striving to be more virtuous requires not only respect for moral principles and control of our contrary emotions but also a system of legally enforced rules and communities of good persons. Exemplars and cultivated good feelings and emotions can also be useful aids along the way, but Kant warns us against attempting to derive our moral standards themselves from examples or feelings. The best any of us can hope for, in Kant’s view, is to make constant progress in our difficult struggle for moral perfection. (shrink)

This paper is an overview of recent discussions concerning the mind–body problem that have been taking place at the interface between philosophy and neuroscience. In it I focus on phenomenal consciousness or “qualia”, which I distinguish from various related issues (sections 1-2). I then discuss various influential skeptical arguments that question the possibility of reductive explanations of qualia in physicalist terms: knowledge arguments, conceivability arguments, the argument from multiple realizability and the explanatory gap argument. None of the arguments is found (...) entirely convincing (section 3). It does not necessarily follow that reductive physicalism is the only option, but it is defensible. However, constant conceptual and methodological reflection is required alongside ongoing research, to keep such a view free from dogmatism and naivety (section 4). (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Nietzsche’s Reading and Private Library, 1885–1889Thomas H. BrobjerOne can easily get the impression that Nietzsche read little, especially later in his life. He criticizes reading because it is not sufficiently life-affirming and Dionysian: “Early in the morning at the break of day, in all the freshness and dawn of one’s strength, to read a book—I call that vicious!...” 1 He also criticizes it for making one reactive and forcing (...) one to be concerned with the thoughts of others rather than with one’s own:My eyes alone put an end to all bookwormishness, in plain terms philology: I was redeemed from the “book,” for years I read nothing—the greatest favour I have ever done myself!—That deepest self, as it were buried and grown silent under a constant compulsion to listen to other selves (—and that is what reading means!) awoke slowly, timidly, doubtfully—but at length it spoke again. 2This impression is strengthened by the fact that in his published books from 1885–88 very few contemporary and minor authors and books are mentioned. [End Page 663] He also explicitly claims that he read little: “It does not perhaps lie in my nature to read much or many kinds of things: a reading room makes me ill.... Caution, even towards new books is rather part of my instinct.” 3 Concretely, he claims in Ecce Homo that, “I have to reckon back half a year to catch myself with a book in my hand. But what was it?—An excellent study by Victor Brochard, les Sceptiques Grecs.” 4 As suggested in a quotation above, and as a major leitmotif in his letters, his health and especially that of his eyes is another reason to assume that he read little. This is also how most philosophers and historians have tended to treat Nietzsche—as an isolated, profound thinker.However, this impression and Nietzsche’s claims here are to a large extent incorrect. Nietzsche was, in fact, a rather substantial reader. This is true not only for his younger days but also for his last four active years, 1885–88. 5 Contrary to his claim that he is hostile to new books, he was very pleased with the large trilingual bookshop Löscher in Turin. He was a frequent and good enough customer to know its “Chef “ and to make contacts through it. 6 Nietzsche frequently used other bookshops, ordered book catalogues, and asked for recommendations of new book titles. 7 Nietzsche found some of the most important books in his life as random discoveries in bookshops, for example, those of Schopenhauer, Stendhal, and Dostoyevsky. Contrary to his claim that a reading room made him ill, he praised Turin for its good libraries, 8 and he wrote to his sister: “one cannot even with ten horses draw me to a place where, if I am correctly informed, not even a good library is to be found.” 9 Libraries were [End Page 664] important for Nietzsche’s reading, and the quality of the libraries was an important determining factor in deciding Nietzsche’s travels and places of residence. He even occasionally wrote to libraries to inquire if they were suitable for his purposes and for deciding if he would visit the town. 10 During the period 1885–88 Nietzsche used the libraries in Nice, Leipzig, Chur, Venice, Turin, and the Hotel Alpenrosen’s library in Sils-Maria. He probably also used the library in Zürich and possibly in other towns, and he planned to visit Stuttgart for the sake of its library.Nietzsche did not have a permanent address during the period discussed in this article and hence travelled frequently. But travelling was difficult for him and almost without exception made him ill, and it was more difficult still with a heavy load of books. During these years Nietzsche lived on a low pension from the University of Basel and constantly worried about his expenses. In spite of this he bought a not insignificant number of books. His private library today contains 60 books published from 1885 to 1888 and in 23 of these Nietzsche has made markings, often extensively, and from several... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 9.3 (2002) 261-264 [Access article in PDF] Mind, Meaning, and the Brain Thomas Fuchs, MD, PhD Keywords: Mind, brain, meaning, translation, depression. A Systemic View of the Mind Progress in brain research over the past two decades demonstrates the power of the neurobiological paradigm. However, this progress is connected with a restricted field of vision typical of any scientific paradigm. The psychiatrist should be (...) aware of this restriction, because, unlike the brain scientist, he deals with patients, not with brains. The restricted view may be described by the terms of (1) reductionism, (2) reification, and (3) isolation.Reductionism: Neurobiology tends to regard subjectivity as a mere by-product of the brain's activity as a symbol-manipulating machine or an information processor. Consciousness becomes an epiphenomon of the neuronal machinery that, operating behind our back, creates the illusion of a continuous self and of an autonomous will (Churchland 1995; Roth 1996).Reification: Mental or subjective states seem to be localizable in the brain; thoughts or feelings, it appears, may be observed in the colored illumination of cortical and subcortical structures. This results in the belief that brain images could also show the cause of a mental illness, or even the illness itself, which then manifests, for instance, in a reduced metabolic activity in certain areas of the cortex.Isolation: As a further consequence, this view isolates the individual patient and considers his illness separated from the interconnections with his environment. However, on these interconnections his personal experiences and dispositions are founded, and it is the actual interpersonal situation that has triggered his present illness.Walter Glannon's paper successfully counters these tendencies toward a neurobiological reductionism with an extended view of the mind: "... the mind is not located in any one place but is distributed among the brain, the body, and the environment." Of course, who observes someone's brain will never see his thoughts, his pain, or his anxiety. For consciousness is not a localizable object or state at all but a process of relating to something: a perceiving of, remembering of, wishing for, aiming at, and so on. Thus on the phenomenological level, there is nothing like a "mental event" that could be isolated from the world and from the stream of conscious experiences. The mind exists only embedded in the world and in the temporal process of life.The same applies to the biological level: Consciousness is based on the continuous interaction of the brain with the organism, and of the organism as a whole with the environment. The role of the brain for mental phenomena is thus comparable to the role of the heart in the circulatory system or of the lung in the respiratory system. Of course, the lung is the central organ of breathing, but respiration may not be restricted to the [End Page 261] lung, nor to the organism as a whole. It means constant exchange with the environment, and there is no sense in asking whether the air taken in still belongs to the surroundings or already to the organism. The same systemic unity is found in the circle of perception and action mediated by the brain: When I am writing a letter, there is no place in the unity of action where my "self" ends and the "world" begins, no border that separates inner and outer worlds.There is another argument to be raised against the reification of the mind if we consider the aspect of a historical biology. From birth on, our mind as well as the correlated brain structures are essentially formed by social and cultural influences. The brain is not inserted into the world as a prefabricated apparatus but through its plastic development in and from the world. Thus it adapts epigenetically to its specific natural and social environment like a key to a lock. This complementarity makes it impossible to restrict one's view to the anatomic organ and requires an interdisciplinary approach to brain-environment investigation, as for example, under the heading of a "social cognitive neuroscience" (Ochsner and Lieberman 2001).As Glannon goes on to argue, to overcome...

Science continually contributes new models and rethinks old ones. The way inferences are made is constantly being re-evaluated. The practice and achievements of science are both shaped by this process, so it is important to understand how models and inferences are made. But, despite the relevance of models and inference in scientific practice, these concepts still remain contro-versial in many respects. The attempt to understand the ways models and infer-ences are made basically opens two roads. The first one is to (...) produce an analy-sis of the role that models and inferences play in science. The second one is to produce an analysis of the way models and inferences are constructed, especial-ly in the light of what science tells us about our cognitive abilities. The papers collected in this volume go both ways. (shrink)

The humanist treatises presented here are only peripheral to the history of logic, but I think historians of logic may read them with interest, if perhaps with irritation. In the early sixteenth century the humanists set about to demolish medieval logic based on syllogistic and disputation, and to replace it in the university curriculum with a 'rhetorical' logic based on the use of topics and persuasion. To a very large extent they succeeded. Although Aris totelian logic retained a vigorous life (...) in the schools, it never again attained to the overwhelming primacy it had so long enjoyed in the northern universities. It has been the custom to take the arguments of the humanists at face value, and the word 'scholastic' has continued to have pejorative overtones. This is easy to understand, because until recently our knowledge of the high period of medieval logic has been slight, and the humanists' testimony as to its decadent state in the sixteenth century has, for the most part, been accepted uncritically. Within the past two decades important work on medieval logic has recovered the brilliant achievement of thirteenth and fourteenth century logicians, philosophers, and natural scientists. New studies are constantly appearing, and the logico-semantic system of the terminists has become fruitful territory not only for historians of logic but also for students of modern linguistics and semiotics.
