In 1614, the German astronomer Simon Mayr published his claim about the discovery of Jupiter’s satellites. In his treatise Mundus Jovialis, Mayr made his assertion in a convoluted but unequivocal manner, earning resentment from Galileo Galilei, who published his harsh protest in 1623 in Il Saggiatore. Though Galileo’s objections were fallacious in some respects, and though numerous scholars took to the field to prove Mayr’s claim, none ever really succeeded, and the historical evidence remains to Mayr’s detriment. (...) On the basis of such historical evidence, including comparisons between Mundus Jovialis and Mayr’s earlier works, Mayr’s independent discovery of the satellites can be ruled out. Indeed, it is very likely that he never observed them before 30 December 1610, nearly a year after Galileo. The lack of a corpus of Mayr’s observations and the inaccuracy of his tables are also puzzling. (shrink)

The paper lists all the predictions and observations of eclipses of Jupiter's satellites 1668–1678 and compares them with modern computations of the these eclipses by J. H. Lieske. We discuss Roemer's method that led to his discovery of the retardment of light and finally we shall interpret Roemer's calculations.

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS The Inference That Makes Science. By ERNAN McMULLIN. The Aquinas Lecture, 1992. Milwaukee: Marquette University Press, 1992. Pp. iv +112. In this ambitious lecture Father Ernan McMullin recapitulates and refines a thesis that has guided his thought for the past forty years. In essence the thesis is this: precisely how science is made has eluded the best minds for centuries, and only in the work of Charles (...) Sanders Peirce, suitably emended by McMullin, has the puzzle finally been solved. " Retroduction " is the inference that makes science. Once this is understood, errors on what constitutes scientific method-those of Aristotle, Aquinas, Galileo, Newton, Bacon, Hume, et al.-can be rectified and one can see science for what it truly is: a complex process of theory appraisal that yields, not definitive truth, but well-established results to which assent can be given with at best "practical certainty," whatever that might be (pp. 91-96). Why McMullin should have chosen such a theme for an Aquinas Lecture is a question that defies reasonable answer. Surely one does not have to he so negative about the thought of Aristotle, Aquinas, and Galileo to advance one's ideas about science in the present day. What McMullin could easily have done, and he hints at this in the last two paragraphs of his lecture (pp. 97-98), is show how retroduction is itself simply a relaxed version of the demonstrative regress, the method actually endorsed by Aristotle, Aquinas, and Galileo. Such a retroductive version, fair enough, yields knowledge of a probable cause, the type of knowledge most typical of modern science. McMullin did not have to embark on the dangerous course of trying to prove that proof and certainty are forever beyond the grasp of science, or that never in the history of science has anyone established a definitive truth. That, in effect, is what McMullin has tried to do, and in the attempt to make the point he fumbles at almost every juncture throughout a very long lecture. To set the record straight more than a review is being re--·quested; perhaps a book, and even that might not suffice for those whose minds are made up. To understand the import of the lecture one must appreciate that it is hut a brief episode in a debate over demonstration in science that has been going on since McMullin first came to the University of Notre Dame in 1954. I myself have published many hooks and articles that engage the very point of his lecture and provide the contra evidence to 131 132 BOOK REVIEWS show elements of continuity in scientific method from Aristotle to the present.

Some idea of the flavor of our debate, however, can be gained from the following. To support his thesis, McMullin has to maintain that Aristotle's proof that the moon is a sphere (from its having phases) and that Galileo's proofs that there are mountains on the moon, that Jupiter has satellites, and that Venus circles the sun (all based on telescopic observations) are not strictly demonstrative, that is, they do not yield true and certain conclusions. He declines to answer a query I have often tendered whether he personally is certain on the basis of pre-spacecraft evidence that the moon is a sphere, that there are mountains on it, that Jupiter has satellites, and so on. Instead he offers the categorical response "that planetary science is not an apodictic science, indeed that no natural science is... (shrink)

For forty years, beginning with the publication of the first modern English translation of the Dialogue Concerning the Two Chief World Systems, Stillman Drake was the most original and productive scholar of Galileo's scientific work of our age. During that time, he published sixteen books on Galileo, including translations of almost all the major writings, and Galileo at Work, the most comprehensive study of Galileo's life and works ever written. His collection Discoveries and Opinions on Galileohas remained in print since (...) its appearance in 1957 and has become the most widely read of all books on Galileo. In addition to his books, Drake published about 130 papers, of which nearly 100 are on Galileo and the rest on related aspects of the history and philosophy of science. This three-volume collection includes eighty of those papers. Drake's papers are an essential supplement to his translations and other books because it was in his papers that he wrote his most detailed technical studies of Galileo's scientific work. There is hardly a subject in Galileo's science that is not considered. Perhaps the most important is the series on mechanics and motion, in which Drake analysed Galileo's manuscript notes recording the experiments by which he discovered and confirmed the law of the acceleration of falling bodies. There are also papers on the notes in which Galileo recorded his discovery of Jupiter's satellites and on other aspects of Galileo's astronomy, including his defence of the Copernican theory. Other papers consider Galileo's life and scientific work in general, exploring what Drake calls the 'scientific personality' of Galileo along with his scientific method and philosophy of science. In addition to the papers on Galileo, there are a number of papers on medieval and early modern science, principally on mechanics, and on the philosophers A.B. Johnson and J.B. Stallo, both of whom influenced Drake's own philosophy of science. (shrink)

The conflict between Jupiter and Juno in the Aeneid is commonly read as a battle between the forces of order and chaos . The present article argues that this schematization, though morally and aesthetically satisfying, fails to account for most of the data. Virgil's Jupiter is in fact concerned solely with power and adulation , despite persistent attempts by readers—and characters in the poem—to see him as benign. By systematically discussing every appearance of Jupiter in the poem, the article seeks (...) to correct the distorted or incomplete views of the god that arise from selective examination. The first section looks at Jupiter's own speeches to illustrate his motivations. The second section demonstrates how these motivations, though frequently misconstrued by the human characters, are confirmed by the glimpses of Jupiter focalized through the omniscient narrator. The third discusses the implications of this portrait of Jupiter for Virgil's vision of Rome and of human happiness. (shrink)

Background This study assessed patient perceptions of the Physician Payments Sunshine Act and opinions toward physicians who receive gifts and/or payments from pharmaceutical or medical device companies. Methods During their office visit, patients attending different specialty clinics volunteered to complete our survey. The survey asks if the patient knows what the Sunshine Act is, then asks questions on 5-point response scales to assess the patient's opinions toward physicians who receive compensation from companies, their self-rated knowledge of physician compensation, and how (...) they believe this compensation affects the cost of care. Results Over 13 months, 523 responses were collected: 8.6% of patients reported having knowledge of the Sunshine Act, 56.8% rated their knowledge of physician compensations as “poor,” and 67.1% agreed with the statement that patients should be aware of the compensation physicians receive. When asked how their opinion toward their physician would change if they learned the physician received free meals or gifts from companies, 58.9% replied “not at all,” and 36.11% of patients did not believe their cost of care would increase if their physician received compensation from companies. Conclusions Most patients were unfamiliar with the Sunshine Act, and believe their knowledge of physician compensation is poor. Over half of the respondents would not change their opinion of their physician based on knowledge of their physician receiving payments/gifts from companies, and over one-third of respondents did not believe such compensation increased the cost of care. The majority of respondents agreed that patients should be aware of payments/gifts to physicians. (shrink)

The identity of the Caesar at "Aeneid", 1.286 is a long-standing problem. The prevailing opinion since Heyne favors Augustus, but a few scholars agree with Servius that the Dictator is meant. In recent years the suggestion that Vergil was being deliberately ambiguous has been advanced as a solution to the problem. I argue the case for Julius Caesar anew. The paper is in five sections. The first four deal respectively with the question of nomenclature; chronology; the descriptive epithets applied to (...) Caesar, especially spoliis Orientis onustum in 289; and the rhetoric of the passage. The fourth section confronts the challenge posed to my reading by the well-known view of Ronald Syme, held to throughout his lifetime, that Julius Caesar was a virtual non-person in the Rome of Vergil's day because the princeps tried to avoid awkward comparison with the Dictator. But this view has been challenged, and I draw on recent work in this area. In the fifth and final section I support my reading with references to Vergil's earlier poetry, attending especially to what it can tell us about Vergil's attitude toward Julius Caesar. Of particular relevance is the use he makes of the sidus Iulium, an image found in the Eclogues and important in connection with the apocalyptic outlook abroad at the time of Caesar's assassination. This section of the paper expands on Servius' generally neglected note, which maintains that the Caesar in question is Julius. (shrink)

In this paper I defend Kuhn’s view of scientific discovery, which involves two central tenets, namely that a scientific discovery always requires a discovery-that and a discovery-what, and that there are two kinds of scientific discovery, resulting from the temporal order of the discovery-that and the discovery-what. I identify two problems with Kuhn’s account and offer solutions to them from a realist stance. Alternatives to Kuhn’s account are also discussed.

By reference to Maxwell's kinetic theory, one feature of hypothetico-deductivism is defended. A scientist need make no inference to a hypothesis when he first proposes it. He may have no reason at all for thinking it is true. Yet it may be worth considering. In developing his kinetic theory there were central assumptions Maxwell made (for example, that molecules are spherical, that they exert contact forces, and that their motion is linear) that he had no reason to believe true. In (...) this paper I develop a position that explains why they were worth considering, and that rejects the retroductive position that a hypothesis is worth considering when, if true, it would explain the observed data.

‘Vergil lässt keinen Zweifel darüber, dass in Wahrheit das Fatum nichts anderes ist als des höchsten Gottes Wille.’ Thus Heinze, apparently following an observation by Seruius auctus, and in turn generally followed by scholars who have subsequently considered the nature of the fata in the Aeneid. But questions concerning the interpretation of the Aeneid are rarely simple; and the question of Jupiter's relationship to the fata may repay further enquiry.

This book, written by a close friend, recounts episodes in the life and career of Eugene M. Shoemaker , an ever‐youthful geologist with a passionate interest in applying geological principles to the moon and planets. In the early 1960s Shoemaker persuaded the U.S. Geological Survey to found an Astrogeology Branch, of which he served as the first director, to search for impact scars on the earth and to map the moon and other planetary bodies. He also played a leadership role (...) in persuading NASA to include scientific investigations in its plans for the Apollo missions. In the 1970s, when images from spacecraft revealed the presence of impact craters on all the rocky planets and satellites, he declared that the impact of solid bodies was the most fundamental process to have taken place on the terrestrial planets. Acting on this insight, he helped to transform geology from an earth‐centered to a planetary science. Eugene Shoemaker was, indeed, a man who made an impact.Details of Shoemaker's career and his many accomplishments have been documented elsewhere, including the numerous citations for honors bestowed upon him and, sadly, his recent obituaries. In this book David Levy, an amateur astronomer and a collaborator with Gene Shoemaker and his wife, Carolyn, gives us personal reminiscences that are available nowhere else. Levy writes in a relaxed, anecdotal style that adds new information and a great sense of fun to this story.Levy tells us, for example, that as a young member of the U.S. Geological Survey, Gene broke with a stern tradition by bringing his wife and children to live with him in his field camps, arguing that their presence made him more rather than less efficient in conducting his work. It was perfectly natural, then, for Gene and Carolyn, decades later, to work together in the Australian outback, where they discovered ten previously unknown impact scars and confirmed several more suspected ones.From 1948 onward Gene harbored a fervent desire to go to the moon, a wish Levy ascribes to his view of a spectacular moonrise over the Colorado Plateau. Back then, such ideas were pure science fiction; but years later, when a real possibility arose, Gene was overcome by a mystifying loss of energy. When his doctor found nothing wrong, Gene and Carolyn took a river trip, hoping to restore his strength and spirits. But his condition worsened until he found a doctor who recognized, on sight, that Gene was a victim of Addison's disease, a formerly fatal illness that could be controlled by cortisone. On taking his second dose, Gene felt his energy returning, but he—like his contemporary President John Kennedy—was obliged to take cortisone every day for the rest of his life. This dashed Gene's hopes of going to the moon himself, but he redoubled his efforts to provide geological training to the fighter‐pilot astronauts who did go there.Beginning in the 1970s, Gene and Carolyn performed systematic searches of the night skies for comets and Near Earth Objects—bodies in orbits that might cause collisions with the earth. Levy joined in many of their searches, and the three of them shared the ultimate triumph of discovering their ninth comet together—Shoemaker‐Levy 9—and watching more than twenty luminous fragments of it plunge one by one into the atmosphere of Jupiter. Several of the pieces sent up dark plumes that lasted more than a year and would have been large enough to envelope the entire earth. No doubt remained that impacts could cause global damage to earth's lithosphere and biosphere were such impactors to strike our own planet. Levy tells us that as the last few pieces disappeared Carolyn lamented the loss of “her string of pearls”; as a consolation, Gene surprised her with the gift of a string of pearls.This book is not, nor was it intended to be, a serious biography based on extensive interviews and archival research. Regrettably, its excellence as a personal account is somewhat marred by the lack of attention from a good fact checker and editor, who would have fixed the slips that appear here and there. For example, on page 41 Levy describes Meteor Crater as being 1.2 kilometers across, and on page 43 as being 1.3 kilometers across—a small but needless discrepancy . On page 144 we read that when Gene brought a carload of students to the Grand Canyon, “a steady snow was falling as they made their way into the canyon. Gene showed a lot of enthusiasm—after all it was his crater!” Clearly, several sentences are missing from between these two sentences. Such lapses are minor, but they are sufficiently common to make the book unreliable as a source of facts. Nevertheless, it is a delightful book that can be strongly recommended to general readers and also to specialists, both for their enjoyment and for the personal details it will add to their knowledge of Eugene Shoemaker's contributions to science.

Kenneth F. Schaffner compares the practice of biological and medical research and shows how traditional topics in philosophy of science—such as the nature of theories and of explanation—can illuminate the life sciences. While Schaffner pays some attention to the conceptual questions of evolutionary biology, his chief focus is on the examples that immunology, human genetics, neuroscience, and internal medicine provide for examinations of the way scientists develop, examine, test, and apply theories. Although traditional philosophy of science has regarded scientific (...) class='Hi'>discovery—the questions of creativity in science—as a subject for psychological rather than philosophical study, Schaffner argues that recent work in cognitive science and artificial intelligence enables researchers to rationally analyze the nature of discovery. As a philosopher of science who holds an M.D., he has examined biomedical work from the inside and uses detailed examples from the entire range of the life sciences to support the semantic approach to scientific theories, addressing whether there are "laws" in the life sciences as there are in the physical sciences. Schaffner's novel use of philosophical tools to deal with scientific research in all of its complexity provides a distinctive angle on basic questions of scientific evaluation and explanation.

In lieu of an abstract, here is a brief excerpt of the content:NEWMAN'S PSYCHOLOGICAL DISCOVERY: THE ILLATIVE SENSE (V. Continued) 15. The Universals. A long and vehement dispute once raged about the reality of universals. Are they only mental creations, forged by the human brain, without any reality outside them, or have they some independent existence apart from their mental reality? Anyhow, there was an apparent contradiction between die universal character of our ideas and the individual character of concrete (...) things. The Scholastics solved this problem by drawing clear distinctions. An idea is an abstraction; as soon as it becomes applicable to a number of objects or things in the same sense, it is a universal idea. The "direct universal" (universale directum seu metaphysicum) as such has no existence apart from our minds, because an existing thing is always bound up with concrete, determining, individualizing notes, and it is these very circumstances or accidents which are ignored by the mind as it strips the thing of its individual characteristics. When the mind reflects on this "direct universal," i.e., on the abstract essence of the thing, it sees that this is to be found in many more things and that it is identical in all those things, and in this way the "reflex or logical universal" is formed (universale reflexum seu logicum). This same essence or quiddity is not really different from the thing itself, but the mind makes abstraction of all accidents, and this foundation makes it possible to apply this idea in die same sense to all other beings of the same kind, whether they are actually existing or not. In other words the universal as a universal has only reality in the mind but it has a foundation or a ground in the thing itself. Newman was not so well acquainted with Scholasticism that he knew and mastered the solution of the problem. As a matter of fact he approached it from quite another angle. Hence when scholastically trained minds read some of his statements on universals, they may feel shocked. They sound very curious, they seem incon418 DR. ZENO, O.F.M. CAP.419 sistent with each other, they apparenüy imply a negation of the objective reality of universals. This makes it necessary to compare the texts and to explain his meaning. a. Newman Inconsistent. We should never lose sight of the fact that Newman had no intention at all to enter the province of philosophy in the restricted sense of the word. "I am only contemplating the mind as it moves in fact, by whatever hidden mechanism,"1 that is what could be put as a heading to every page of the Grammar of Assent. And when he virtually deals with metaphysics, he wants us to consider his statements as hypotheses, or as propositions stated only by the way, and in this department he always wishes "to speak under correction." This explains how he could refer to the universale metaphy sicum and the universale directum in a very correct way without realizing he was teaching Scholastic doctrine. As far as I know, it is Professor Walgrave who has first drawn attention to this fact,2 when he dealt with Newman's alleged conceptualism. Newman states that "even one act of cruelty, ingratitude, generosity or justice reveals to us at once intensive the immutable distinction between those qualities and their contraries; that is, in that particular instance and pro bac vice."3 The same holds for the opposites: right and wrong, true and false, just and unjust, beautiful and deformed.4 In one experience, therefore, he sees a thing as an immutable, absolute quiddity, which objectively and in the same sense belongs to all possible things of the same kind, although the mind does not yet explicidy confirm this universal applicability. The contemplated quality remains limited to the particular case; but in its absoluteness it is stripped of all individual, changeable and concrete characteristics. This is the metaphysical universal of the Scholastics. But Newman also mentions the logical universal when he says: "As we form our notion of whiteness from the actual sight of snow, a lily or a cloud, so, after experiencing the sentiment of approbation which arises in us on the sight of certain...

In this paper I consider two accounts of scientific discovery, Robert Hudson's and Peter Achinstein's. I assess their relative success and I show that while both approaches are similar in promising ways, and address experimental discoveries well, they could address the concerns of the discovery sceptic more explicitly than they do. I also explore the implications of their inability to address purely theoretical discoveries, such as those often made in mathematical physics. I do so by showing that extending (...) Hudson's or Achinstein's account to such cases can sometimes provide a misleading analysis about who ought to be credited as a discoverer. In the final sections of the paper I work out some revisions to the Hudson/Achinstein account by drawing from a so-called structural realist view of theory change. Finally, I show how such a modified account of discovery can answer sceptical critics such as Musgrave or Woolgar without producing misleading analyses about who ought to receive credit as a discoverer in cases from the mathematical sciences. I illustrate the usefulness of this approach by providing an analysis of the case of the discovery of the Casimir effect. (shrink)

Currently, we find ourselves in a paradigm in which we believe that accepting climate change data will lead to a kind of automatic action toward the preservation of our environment. I have argued elsewhere (Fried 2020) that this lack of civic action on climate data is significant when placed in the historical, military context of the technologies that collect this data––Earth remote sensing technologies. However, I have not yet discussed the phenomenological or moral implications of this context, which are deeply (...) interconnected. In this paper, I assert that Earth remote sensing technologies can, if we are not careful, lead us to a kind of environmental deskilling. This assertion comes in four parts. First, the military context of Earth remote sensing technologies––which collect important data on climate change––acts as a kind of stability, as defined by Don Ihde and others. Second, I invoke Sir Patrick Heelan to argue that the theoretical underpinnings of Earth systems science do not translate from military to environmental praxes as we imagine they do. Third, Hannah Arendt makes the case that a state’s trust in simplifying narratives like that of climate data, meant to create “islands” of certainty in an uncertain world, can be self-defeating. That is to say, they can silence public action. I extend these arguments through Vallor’s analysis of moral deskilling, in which she points out that an overemphasis on autonomous data collection––and trust in a kind of automated decision-making on that data––can deskill us from important questions relevant to our collective flourishing. In all of these examples, the lines between environmental and military research are blurry. (shrink)

"In preparing this remarkable book, Ernest Hook persuaded an eminent group of scientists, historians, sociologists and philosophers to focus on the problem: why are some discoveries rejected at a particular time but later seen to be valid?

In the paper I explore the relations between a relatively new and quickly expanding branch of artificial intelligence –- the automated discovery systems –- and some new views advanced in the old debate over scientific realism. I focus my attention on one such system, GELL-MANN, designed in 1990 at Wichita State University. The program's task was to analyze elementary particle data available in 1964 and formulate an hypothesis (or hypotheses) about a `hidden', more simple structure of matter, or to (...) put it in contemporary terms –- the discovery of quarks. The central thesis of my paper is that systems like GELL-MANN not only discover (or rediscover) the hidden structure of matter, but also provide independent strong evidence in favor of scientific realism about entities involved in that structure. I make an attempt to show how an argument for scientific realism about sub-microscopic entities can be constructed that would parallel Ian Hacking's `argument from coincidence' presented with respect to microscopic objects in his famous book Representing and Intervening.

In 1983, Dr. J. Robin Warren and Dr. Barry Marshall reported finding a new kind of bacteria in the stomachs of people with gastritis. Warren and Marshall were soon led to the hypothesis that peptic ulcers are generally caused, not by excess acidity or stress, but by a bacterial infection. Initially, this hypothesis was viewed as preposterous, and it is still somewhat controversial. In 1994, however, a U. S. National Institutes of Health Consensus Development Panel concluded that infection appears to (...) play an important contributory role in the pathogenesis of peptic ulcers, and recommended that antibiotics be used in their treatment. Peptic ulcers are common, affecting up to 10% of the population, and evidence has mounted that many ulcers can be cured by eradicating the bacteria.. (shrink)

The title refers to Anselm's insight into the modal uniqueness of the divine existence and the proof based upon it in Proslogium III. Hartshorne continues his vigorous defense of "the Proof," his polemic against its critics, most of whom confuse it with the weaker one in Proslogium II, and his attempt to show that Anselm's discovery is ultimately viable only in the context of neo-classical theism. In the second half of the book a variety of responses to the proof, (...) from Gaunilo to several contemporaries, are examined and criticized. While this does not add substantially to the presentation and defense of the argument given in the first half, it does provide ample evidence of the way in which a host of philosophical questions are brought into sharp focus by reflecting on Anselm. Some of these, e.g., the theory of modalities, receive important attention which was lacking in The Logic of Perfection. The author's own position has not changed, though he now seems more impressed than previously by Barth's treatment of Anselm.—M. W. (shrink)

Many investigations into the world, including philosophical ones, aim to discover causal knowledge, and many experimental methods have been developed to assist in causal discovery. More recently, algorithms have emerged that can also learn causal structure from purely or mostly observational data, as well as experimental data. These methods have started to be applied in various philosophical contexts, such as debates about our concepts of free will and determinism. This paper provides a “user's guide” to these methods, though not (...) in the sense of specifying exact button presses in a software package. Instead, we explain the larger “pipeline” within which these methods are used and discuss key steps in moving from initial research idea to validated causal structure. (shrink)

What is it that turns a new observation into a true scientific discovery? And who may claim the credit? Theoreticians of science, the foremost thinkers of their times among them, have tried to answer these fundamental questions about the nature of scientific progress and discovery. With clear insight and the chemical as well as philosophical wisdom gained from over fifty years as a practising chemist, Jerome Berson puts their theories to the test. The development of chemistry into a (...) "modern" science during the last two centuries provides him with ample cases to illustrate the way scientific progress really happens. Kekul?'s struggle to arrive at a structure for benzene, the paradigm change that was necessary to accept the reality of molecular rearrangements, and other episodes are retold here from the philosopher's as well as from the practitioner's perspective, shedding light on the way scientists think and act. Berson's account of the rather unphilosophical way in which scientific discoveries are made includes the realization that even a false hypothesis, such as Woodward's ideas about the biosynthesis of strychnine, may help rather than hinder scientific progress. Scientists of all ages, as well as many non-scientists, will find this a highly readable and unusual book. (shrink)

In this work, we provide a broad overview of the distinct stages of E-Discovery. We portray them as an interconnected, often complex workflow process, while relating them to the general Electronic Discovery Reference Model (EDRM). We start with the definition of E-Discovery. We then describe the very positive role that NIST’s Text REtrieval Conference (TREC) has added to the science of E-Discovery, in terms of the tasks involved and the evaluation of the legal discovery work (...) performed. Given the critical nature that data analysis plays at various stages of the process, we present a pyramid model, which complements the EDRM model: for gathering and hosting; indexing; searching and navigating; and finally consolidating and summarizing E-Discovery findings. Next we discuss where the current areas of need and areas of growth appear to be, using one of the field’s most authoritative surveys of providers and consumers of E-Discovery products and services. We subsequently address some areas of Artificial Intelligence, both Information Retrieval-related and not, which promise to make future contributions to the E-Discovery discipline. Some of these areas include data mining applied to e-mail and social networks, classification and machine learning, and the technologies that will enable next generation E-Discovery. The lesson we convey is that the more IR researchers and others understand the broader context of E-Discovery, including the stages that occur before and after primary search, the greater will be the prospects for broader solutions, creative optimizations and synergies yet to be tapped.

The rise of world literature is the most noticeable phenomenon in literary studies in the twenty-first century. However, truly well-known and globally circulating works are all canonical works of European or Western literature, while non-European and even "minor" European literatures remain largely unknown beyond their culture of origin. World Literature as Discovery: Expanding the World Literary Canon argues that world literature for our time must go beyond Eurocentrism and expand the canon to include great works from non-European and "minor" (...) European literatures. As much of the world's literature remains untranslated and unknown, the expansion will be an exciting process of discovery. By discussing fundamental questions around canon, circulation, aesthetic values, translation, cosmopolitanism and the literary universal, Zhang Longxi proposes a new and liberating concept of world literature that will shape world literature worthy of its name. This book speaks for a more inclusive idea of world literature, and shows students and scholars alike that all the literary traditions, particularly non-European traditions, will be able to make important contributions and expand the canon of world literature.

According to Plato's Republic, human knowledge in highest form owes its existence to a priori discoveries made during the course of dialectical investigations. Being a priori, such discoveries are neither empirical observations nor conclusions based upon empirical observations, although in some cases they may be “occasioned” by experience. They are matter for intellectual, not literal, vision, and making them is what distinguishes the successful philosopher from the non-philosopher. Thus, in the Phaedo, Plato is in a position to argue that the (...) separation of the soul from the body in death is no evil for a genuine philosopher: he has no need to rely on the bodily senses in order to acquire philosophical knowledge; and he is well free of the errors and confusion generated by the senses, and of the physical desires nourished in the soul as a result of residing in a body.

Reasoning in Biological Discoveries brings together a series of essays, which focus on one of the most heavily debated topics of scientific discovery. Collected together and richly illustrated, Darden's essays represent a groundbreaking foray into one of the major problems facing scientists and philosophers of science. Divided into three sections, the essays focus on broad themes, notably historical and philosophical issues at play in discussions of biological mechanism; and the problem of developing and refining reasoning strategies, including interfield relations (...) and anomaly resolution. Darden summarizes the philosophy of discovery and elaborates on the role that mechanisms play in biological discovery. Throughout the book, she uses historical case studies to extract advisory reasoning strategies for discovery. Examples in genetics, molecular biology, biochemistry, immunology, neuroscience and evolutionary biology reveal the process of discovery in action. (shrink)

: In 1856, Michael Faraday (1791–1867) conducted nearly a year's worth of research on the optical properties of gold, in the course of which he discovered the first metallic colloids. Following our own discovery of hundreds of the specimens prepared by Faraday for this research, the present paper describes the cognitive role of these "epistemic artifacts" in the dynamics of Faraday's research practices. Analysis of the specimens, Faraday's Diary records, and replications of selected procedures (partly to replace missing kinds (...) of specimens and partly to understand the "tacit knowledge" implicated in Faraday's research) are outlined, and a reconstruction of the events surrounding the initial discovery of metallic colloids is presented.

This work articulates two thesis: one Socratic and one Platonic; and displays how the first one is heir of the second. The Socratic one is called the principle of priority of definition; the Platonic one is the Recollection theory. The articulation between both theses is possible due to the Meno’s paradox, which makes a criticism on the first thesis, but it is solved with the second one. The consequence of this articulation is a new interpretation of the Recollection theory, as (...) a theory of knowledge acquisition that depends, mainly, on a distinction between knowledge and true opinion. To conclude, a new interpretation of the knowledge/true opinion distinction is displayed –not in the traditional fashion, evaluating the propositions one by one, and in an atomic way–, but as big blocks or chains of propositions shaping knowledge through explanatory reasoning (aitías logismós).

remarks some lessons about self-knowledge (and some other self-relations) as well as use them to throw some light on what might seem to be a fairly distant area of philosophy, namely, Sartre's view of the person as of a divided nature, divided between what he calls the self-as-facticity and the self-as-transcendence. I hope it will become clear that there is not just perversity on my part in bringing together Wittgenstein and the last great Cartesian. One specific connection that will occupy (...) me here is their shared hostility to the idea of theoretical certainty as our model for the authority of ordinary self-knowledge, and their relating of such a theoretical model to specific forms of self-alienation. This, in turn, is related to another concern they share, a concern with the difficulties, philosophical and otherwise, in conceiving of oneself as but one person in the world among others. (shrink)

AI technologies have recently shown remarkable capabilities in various scientific fields, such as drug discovery, medicine, climate modeling, and archaeology, primarily through their pattern recognition abilities. They can also generate hypotheses and suggest new research directions. While acknowledging AI’s potential to aid in scientific breakthroughs, the paper shows that current AI models do not meet the criteria for making independent scientific discoveries. Discovery is an epistemic achievement that requires a level of competence and self-reflectivity that AI does not (...) yet possess. (shrink)

This paper argues, first, that recent studies of experimentation, most notably by Deborah Mayo, provide the conceptual resources to describe scientific discovery's early stages as error-probing processes. Second, it shows that this description yields greater understanding of those early stages, including the challenges that they pose, the research strategies associated with them, and their influence on the rest of the discovery process. Throughout, the paper examines the phenomenon of "chemical hormesis" (i.e., anomalous low-dose effects from toxic chemicals) as (...) a case study that is important not only for the biological sciences but also for contemporary public policy. The resulting analysis is significant for at least two reasons. First, by elucidating the importance of discovery's earliest stages, it expands previous accounts by philosophers such as William Wimsatt and Lindley Darden. Second, it identifies the discovery process as yet another philosophical topic on which the detailed studies of the "new experimentalists" can shed new light. (shrink)

Mathematics has been the most successful and is the most mature of the sciences. Its first great master work – Euclid's ‘Elements’ – which helped to establish the field and demonstrate the power of its methods, was written about 2400 years ago; and it served as a standard text in the mathematics curriculum well into the twentieth century. By contrast, the first comparable master work of physics – Newton's Principia – was written 300 odd years ago. And the juvenile science (...) of biology only got its first master work – Darwin's ‘On the Origin of Species’ – a mere 150 years ago. The development of the subject has also been extraordinarily fertile, particularly in the last three centuries, and it is perhaps only in the last century that the other sciences have begun to approach mathematics in the steady accumulation of knowledge that it has been able to offer. There has, moreover, been almost universal agreement on its methods and how they are to be applied. What we require is proof; and, in practice, there is very little disagreement over whether or not we have it. The other sciences, by contrast, tend to get mired in controversy over the significance of this or that experimental finding or over whether one theory is to be preferred to another. (shrink)

My aim here is to raise a few questions concerning the problem of representation in scientific discovery computer programs. Representation, as Simon says in his paper, "imposes constraints upon the phenomena that allow the mechanisms to be inferred from the data". The issue is obviously barely outlined by Simon in his paper, while it is addressed in detail in the book by Langley, Simon, Bradshaw and Zytkow (1987), to which I shall refer in this note. Nevertheless, their analysis would (...) appear to leave open certain issues related to the nature of the "constraints" imposed by representation on problem solving strategies. (shrink)

Since the date of my last report upon this subject there has been little to chronicle in regard to the excavations in the Forum. The work of clearing the superficial strata which cover the remainder of the site of the Basilica Aemilia is proceeding somewhat slowly, and the level at which interesting discoveries may be expected has not yet been reached. Nor is the Forum Museum as yet ready. New discoveries have been confined to small excavations on the S.E. and (...) the S.W. sides of the Arch of Titus, where large blocks of travertine, which originally belonged to some other building, and floors in concrete and opus spicatum, with foundations and drains below them, have been found, orientated more or less in correspondence with the older Sacra Via. Two parallel walls at a lower level, however, of large blocks of tufa may well be connected with the earlier temple of Jupiter Stator, which preceded the massive concrete foundation of the temple as we have it, which is orientated with the temple of Venus and Rome and the Arch of Titus.
