In the article, I try to refute an old and widespread superstition according to which the new political philosophy created by Niccolo Machiavelli breaks with classical political philosophy by taking a novel position toward the political; that is, that classics were idle “idealists” while Machiavelli is a coldblooded “realist”. To do that, I compare the most explicit part of The Prince (chapters XIV-XIX) with the end of the fifth book of Aristotle’s Politics and attempt to show that in the most (...) pivotal chapters of his most famous work, the Florentine, in fact, often borrows Aristotle’s advice on how to preserve a tyrannical rule.

Timothy Knepper’s book is divided into two parts, the first and more critical of which seeks to uncover the limits and weaknesses of analytic and continental philosophy of religion, while the second and more constructive section seeks to develop an alternative and more fruitful way of practising philosophy of religion, “one that is historically grounded and religiously diverse” (p. xiii). Much of the impetus behind the book derives from feelings of dismay and dissatisfaction, familiar especially to religious studies scholars, over (...) the fact that “philosophy of religion often takes as its primary object of inquiry either ahistorical theism or postmodern philosophy, not the religions of the world in their historical complexity and cultural diversity” (p. ix). I found this to be a clear, well-argued and often provocative book, but also one flawed in some respects in its attempt to renew and reconceive the philosophy of religion.The starting-point of Chapter 1 (The End and Ends of Philosoph.

In everyday life it is common to judge people morally responsible for their actions, but there is a time-honored philosophical challenge to this practice with which we are all familiar. The challenge can be put briefly as follows: moral responsibility requires that agents have a certain kind of control that is compatible with neither causal determinism nor its contradictory, causal indeterminism; hence moral responsibility is impossible. Haji notes that judgments about moral responsibility- which I will call hypological judgments—are not the (...) only category of moral, or morally relevant, judgments. There are also deontic judgments, which have to do with moral obligation, right, and wrong; aretaic judgments, which have to do with moral virtue and vice; and axiological judgments, which have to do with intrinsic and extrinsic value. In principle, a challenge to all such judgments can be made that parallels the challenge to hypological judgments: that they presuppose a certain kind of control that is compatible with neither determinism nor indeterminism and are therefore to be rejected. It is a surprising fact that, whereas the challenge to hypological judgments has been the subject of intense debate for centuries, the analogous challenges to the other kinds of judgments have received comparatively little, if any, attention. In this book, Haji seeks to rectify this omission. He concerns himself primarily with the challenge to deontic judgments. During the course of his discussion he deals in depth with the original challenge to hypological judgments, devotes a chapter to the challenge to aretaic judgments, and makes certain remarks in passing about the challenge to axiological judgments.

Alan Weir’s new book is, like Darwin’s Origin of Species, ‘one long argument’. The author has devised a new kind of have-it-both-ways philosophy of mathematics, supposed to allow him to say out of one side of his mouth that the integer 1,000,000 exists and even that the cardinal ℵω exists, while saying out of the other side of his mouth that no numbers exist at all, and the whole book is devoted to an exposition and defense of this new view. (...) The view is presented in the book in a way that can make it difficult for the reader to trace the main line of argument: with a great deal of apparatus, and with a great many digressions into subordinate issues. In what follows I will try to stick to what I take to be the essentials, even at the risk of oversimplifying some central but complicated issues, and at the cost of neglecting some interesting but peripheral ones.In chapter 1, the author introduces a distinction between what he calls ‘two aspects of meaning’ and dubs informational content and metaphysical content. Informational content is the aspect of meaning of primary interest to linguists, and the one of which speakers themselves are generally aware, at least upon reflection. Metaphysical content is supposed to be another aspect of meaning primarily of interest to philosophers. The basic idea is that if there are standards of correctness for assertions of a certain kind, then such an assertion may be called ‘true’ when those standards are met, even though the kind of correctness involved is not correctness in representing how the world is. What the world must be like in order for the utterance to be true is the metaphysical content of the assertion, but it need not be part of its …. (shrink)

How much should we know about the underlying structure of a technological artifact in order to understand its history? Quite a bit, according to the authors of The First Computers: History and Architectures. This book, a collection of papers presented at the International Conference on the History of Computing in 1998, is aimed at computer scientists and programmers as well as historians of science and technology. The term “architecture” is used in computing to refer to the structure and capabilities of (...) a computer; it includes both logical design and physical design . Architecture is an abstraction that helps the authors make comparisons between computers from different countries and eras.The First Computers brings together a wealth of information on computers from the 1940s and 1950s, which the editors present in five main sections. Part 1, “History, Reconstructions, Architectures,” addresses general themes in the history of computing. Michael Mahoney's chapter, “The Structures of Computation,” examines the relationship between computer science and “pure” mathematics. Even in its most theoretical aspects, Mahoney notes, computer science has always focused pragmatically on feasible implementations of mathematical ideas, thus “blurring commonly made distinctions among science, engineering, and craft practice” . Robert W. Seidel examines the rationale for reconstructing historic computers, an activity that has engaged many of the book's contributors. Seidel notes that “as the artifacts of modern computing become invisible, older, larger computers supply a symbol of computing to practitioners, the public, and patrons which is not only visible, but comprehensible” .The four remaining parts cover computing developments in America, Germany, Britain, and Japan. The American computers include the Atanasoff‐Berry Computer, Aiken Mark I, ENIAC, and the Institute for Advanced Study computer. The section on Germany contains several chapters on Konrad Zuse as well as on such developments as the Göttingen machines, which may not be that well known. Britain is represented by the Colossus, Manchester Mark I, Atlas, and EDSAC. Perhaps least familiar to historians are the Japanese computers: Seiichi Okoma surveys nine early Japanese computers, and Eiiti Wada describes the PC‐1, which he helped build. Many of the chapters, especially those written by engineers, begin with a brief history of the machine followed by a detailed technical description of its design and operation. The contributions by historians tend to describe the computer's features in more general terms and discuss the intellectual, organizational, and economic context in which the machine was built.Because so many of the authors are technically trained, they are able to offer in‐depth information on the theoretical underpinnings and design of early computers. But often the discussion is difficult to follow, even for historians working in this area. Tony Sales's chapter on the Colossus, a British code‐breaking computer, exemplifies the strengths and weaknesses of accounts written by technical specialists. Sales begins with a clear and engaging narrative of the origins of the Colossus, its method for decoding messages, and its significance to the Allied effort in the Second World War. He then veers into a highly technical discussion that will likely be opaque to readers unfamiliar with terms such as “thyratron rings.” The final section is a personal story of Sales's successful effort to have the machine rebuilt. Like the book as a whole, Sales's chapter can be read for a quick introduction to a milestone in the history of computing or for insight into the meanings embedded in technological artifacts—but readers should be prepared to decipher some formidable technical jargon along the way.

War Machines: Transforming Technologies in the U.S. Military, 1920–1940, is not as broad as its title might suggest. Timothy Moy does indeed propose a broad thesis, that institutional culture plays a large, though seldom acknowledged, role in technological innovation. But he addresses only two very particular case studies of military innovation between the world wars. The longer reviews the Army Air Force's development of the technology for precision bombing; the shorter examines the U.S. Marine Corps's development of the technology for (...) amphibious assault. What primarily shaped these innovations were, in Moy's view, the particular cultures of the air force and marines and their internal politics rather than the more commonly cited technical or industrial imperatives.The book is divided into two parts, each of four chapters, plus an introduction and a conclusion . As we might expect of a study derived from a Berkeley history of science dissertation, War Machines rests on a reasonably solid research base. The two stories are told separately, however, and differ significantly in both structure and documentation. Part 1, “Precision Bombing,” alternates chapters on doctrine and technology. Chapters 2 and 4 follow the air force adoption of strategic bombing as a mission to win independence from the army. Judging by the endnotes, both chapters rest chiefly on secondary sources and are less analytical than assertive. Chapters 3 and 5 trace the air force effort to find the bombsights and bombers that its self‐chosen mission required. These chapters offer a more extensively documented and persuasive narrative than those on doctrine, although the two are not very well integrated. Part 2, “Amphibious Landing,” in contrast, integrates doctrine, training, and technology in a single narrative. It begins with the marines adopting advanced base defense and amphibious warfare to define missions that would sustain institutional independence, then follows the interaction of doctrinal evolution, training exercises, and technological development. These chapters are based much more heavily on archival research than those in Part 1.Moy is a fine writer, but he sometimes lapses into phrasemaking at the expense of explanation. Referring to the air force as a “high‐tech” organization, for instance, he claims that “the airmen's institutional self‐image as futuristic and gallant knights of the sky shaped the vision of strategic bombing they articulated and embraced. Daylight bombing grew out of this high‐tech culture” . How bombing squares with a “knights of the sky” self‐image he never explains. Nor does he ever fully address the specifics of one of his major categories, high‐tech versus low‐tech innovation. This becomes all the more troublesome when he extends the distinction by characterizing the air force as high tech, the marines as low tech. Quite apart from the anachronistic usage, this contrast tends to become more label than analysis.However well chosen Moy's cases, two seems a slender base to sustain his thesis. One feature of his argument that I find particularly problematic is the almost complete absence of internal opposition. Neither airmen nor marines spoke with one voice about the choice of a single mission to define their service. Moy mentions the advocates of pursuit aviation only in passing, for instance, and is completely silent about any dissidence among marines. This places him in the company of a long line of historians and social scientists who have studied controversies over military innovation exclusively from the viewpoint of those perceived to be on the winning side. In his conclusion Moy does briefly discuss the alternatives each service might have chosen; but however well done, it is too little and too late. (shrink)

I argue that in the seven “dogmas of the universal faith,” which are introduced in chapter XIV of the Theological-Political Treatise, Spinoza reinterprets the traditional view of a minimal credo required for salvation. The dogmas are dialectical propositions that are true insofar as they are practically useful. Instead of obtaining salvation for the soul, the dogmas aid in the preservation of the body, particularly through the regulation of religion within the state. I show that reading the dogmas in light (...) of Spinoza’s method of interpreting Scripture is crucial to the understanding of their function in religion. In conclusion, I claim that the dogmas do not lead to the abolition of traditional religion, as some have claimed, but rather support the toleration of diverse religious practices. (shrink)

Hobbes’ account of these issues is conspicuously brief and puzzling. Indeed it has been criticized by some commentators as ‘confused.’ I hope to show, however, that it appears confused only because it has not been read with sufficient precision. Properly understood, Hobbes’ account is both exact and profound. It is also, in my view, far more interesting as a conception of natural right than the modern ‘confusions’ which have come to be read into it.To show this, the text must be (...) read as it is presented: on its own terms, analytically and exactly. In what follows, therefore, I shall focus upon Hobbes’ definitive account of the right of nature in chapter XIV of Leviathan, with only minimal reference to other passages and other works. I do not pretend that this is the only possible approach to Hobbes on this point; but it does show how his account may be read intelligibly, and with greater respect for the power and precision of his thought.

Excerpt from Benedetto Croce: Philosopher of Art and Literary Critic In Italian of course there are several aids to the study of Croce, including a full bibliography, completely indexed; see Appendix 2. But there are still a number of unsettled points concerning the development of Croce's thought and the chronology of his doctrines. The current view of this chronology as it refers to aesthetic theory is cited above, but each date may be pushed backwards. The theory of art as expression (...) is already outlined in a book of 1893. The lyrical intuition, announced in the Heidelberg lecture of 1908, was already formulated in the first draft of the Logic The first formulation of ex pression as an a priori synthesis is dated, even by some Italian scholars, in 1912, but it is to be found in the Logic of 1908. The cosmic intuition is dated 1918, but it is already found in a book which goes back to 1915. My book gives some attention to chronology, but does not attempt to solve all the relative problems. A complete study of Croce's intellectual develop ment still remains to be done. However, the ultimate aim of this work is not biographical or purely historical but critical. The goal has been to see whether there is a practical theory of literary criticism in Croce. Are the problems of criticism solved more clearly and satisfactorily when viewed from Croce's standpoint? Is the question I have asked myself throughout. Accordingly, I have endeavored to see things as much as possible from his point of View and to present his doctrines in the most favorable light. However, dissent will appear on three main points of doctrine: Croce's handling of the image in his theory of practical criticism (chapters III and VIII), his third or universalistic aesthetics (chapter XI) and his later criticism of contemporary writing (chapter XIV). In other words, Croce in this book has been criticized only from within, when his conclusions appeared to be inconsistent with his premises. Of course these premises themselves are sub jcet to discussion. But this discussion is profitable only when it arises out of complete knowledge of what Croce had to say.

In lieu of an abstract, here is a brief excerpt of the content:160 BOOK REVIEWS or orthopraxis (which is revealed insightfully as a false dilemma [Chapter XII]), and the Church both in its struggle for human rights (Chapter XIII) and in its missionary activity (Chapter XIV). The translation of the work is quite adequate, though there are some places where it misses the nuance of Geffre's text, as when it asserts that "there is no knowledge..." (p. 14), (...) instead of saying that "it [discourse] is not a knowledge" (French edition, Paris, 1983; p. 23). It can also tend to render the text unintelligible, as when it speaks of "our habit of judging... the exclusive place of theological truth" (p.54), instead of "our habit of making judgment ••• the exclusive place of theological truth " (French edition, p.76·77). Then, there are moments when it simply says the opposite of what the author intends. Thus Thomas Aquinas is presented as one of those who tend to replace the authority of Scripture with the authority of the magisterium (p.48) instead of being distinguished from them (French edition, p.68), and scientific exegesis and historical method are credited with helping to " bridge the gulf " between exegetes and theologians (p.13), instead of being criticized for helping to " dig the ditch (creuser le fosse) " that separated them (French edition, p.21). Geffre concludes his book with an epilogue where he comments both critically and hopefully on the recent history of Catholic theology in France. In this he is able both to review the major themes of the book and to establish a challenging program for future work in hermeneutical theology. Despite the reservations I have mentioned concerning some of his views, I think it can be said that Ge:ffre's careful scholarship and insightful arguments, combined with is penetrating grasp of the contemporary theological scene which is evident in his copious notes and references, may represent one of the first flowers of the " new theological spring " of which he speaks. MICHAEL J. DODDS, O.P. Dominican School of Philosophy and Theology Berkeley, California Life and Faith: Psychological Perspectives on Religious Experience, by W. W. MEISSNER, S.J. Washington, D.C.: Georgetown University Press, 1987. Pp. xviii + 302. Bibliography. $24.95. Fr. Meissner is continuing his career-long research into the overlaps of psychoanalysis and religion, and in this book is broadening his perspectives to embrace several other areas of contemporary developmental psychology, in a wide.arching synthesis of broad generaliza· BOOK REVIEWS 161 tions. His underlying thesis is that psychoanalysis, especially in its later ego-psychology and object relationships developments, has insights to contribute to the psychology of religion, and, along with other psychologies of development, clarifies and concretizes the understanding of religion-as-lived, counterpointing the contributions of theology. The book has three sections. In the first section, the author reflects on a psychology of grace, and sets up a developmental schema of the steps toward spiritual identity, paralleling Freud's psychosexual stages and Erikson's psychosocial stages. He conceptualizes the psychospir· itual stages in terms of the theological virtues, partially subdivided into Gospel virtues, and two of the cardinal virtues. Thus his eight stages emerge as faith/hope, contrition, penance/temperance, fortitude, hu· mility, love of neighbor, service/zeal and charity. Prudence, presum· ably, would relate more to a Piagetian schema, although prudence would certainly also be affected by areas of psychological conflict, while justice would probably be considered a superego derivative. The second section of the book deals with faith/hope, the first stage of psychospiritual development. The author uses Kierkegaard's analysis of faith as his theological standard. Whether this understanding of faith, in which the formal motivation is absurdity, is preferable to a faith whose formal motive is "because nothing is impossible for God," is debatable. In any event, Kierkgaard's faith would seem to belong more to a stage of final purification than to any earlier developmental phases. In presenting the stages of faith development, Meissner uses Fow· ler's schema, based on -Piaget's and Kohlberg's studies, (cognizant of Rothman and Lichter's criticisms in terms of the influence of sociopolitical ideologies, but making no reference to Loevinger's critique from women's perspectives), along...

ABSTRACT I argue that this examination and appreciation for the shift to abductive reasoning should be extended to the intersection of neuroscience and novel brain-computer interfaces too. This paper highlights the implications of applying abductive reasoning to personalized implantable neurotechnologies. Then, it explores whether abductive reasoning is sufficient to justify insurance coverage for devices absent widespread clinical trials, which are better applied to one-size-fits-all treatments. INTRODUCTION In contrast to the classic model of randomized-control trials, often with a large number of (...) subjects enrolled, precision medicine attempts to optimize therapeutic outcomes by focusing on the individual.[i] A recent publication highlights the strengths and weakness of both traditional evidence-based medicine and precision medicine.[ii] Plus, it outlines a tension in the shift from evidence-based medicine’s inductive reasoning style (the collection of data to postulate general theories) to precision medicine’s abductive reasoning style (the generation of an idea from the limited data available).[iii] The paper’s main example is the application of precision medicine for the treatment of cancer.[iv] I argue that this examination and appreciation for the shift to abductive reasoning should be extended to the intersection of neuroscience and novel brain-computer interfaces too. As the name suggests, brain-computer interfaces are a significant advancement in neurotechnology that directly connects someone’s brain to external or implanted devices.[v] Among the various kinds of brain-computer interfaces, adaptive deep brain stimulation devices require numerous personalized adjustments to their settings during the implantation and computation stages in order to provide adequate relief to patients with treatment-resistant disorders. What makes these devices unique is how adaptive deep brain stimulation integrates a sensory component to initiate the stimulation. While not commonly at the level of sophistication as self-supervising or generative large language models,[vi] they currently allow for a semi-autonomous form of neuromodulation. This paper highlights the implications of applying abductive reasoning to personalized implantable neurotechnologies. Then, it explores whether abductive reasoning is sufficient to justify insurance coverage for devices absent widespread clinical trials, which are better applied to one-size-fits-all treatments.[vii] ANALYSIS I. The State of Precision Medicine in Oncology and the Epistemological Shift While a thorough overview of precision medicine for the treatment of cancer is beyond the scope of this article, its practice can be roughly summarized as identifying clinically significant characteristics a patient possesses (e.g., genetic traits) to land on a specialized treatment option that, theoretically, should benefit the patient the most.[viii] However, in such a practice of stratification patients fall into smaller and smaller populations and the quality of evidence that can be applied to anyone outside these decreases in turn.[ix] As inductive logic helps to articulate, the greater the number of patients that respond to a particular therapy the higher the probability of its efficacy. By straying from this logical framework, precision medicine opens the treatment of cancer to more uncertainty about the validity of these approaches to the resulting disease subcategories.[x] Thus, while contemporary medical practices explicitly describe some treatments as “personalized”, they ought not be viewed as inherently better founded than other therapies.[xi] A relevant contemporary case of precision medicine out of Norway focuses on the care of a patient with cancer between the ventricles of the heart and esophagus, which had failed to respond to the standard regimen of therapies over four years.[xii] In a last-ditch effort, the patient elected to pay out-of-pocket for an experimental immunotherapy (nivolumab) at a private hospital. He experienced marked improvements and a reduction in the size of the tumor. Understandably, the patient tried to pursue further rounds of nivolumab at a public hospital. However, the hospital initially declined to pay for it given the “lack of evidence from randomised clinical trials for this drug relating to this [patient’s] condition.”[xiii] In rebuttal to this claim, the patient countered that he was actually similar to a subpopulation of patients who responded in “open‐label, single arm, phase 2 studies on another immune therapy drug” (pembrolizumab).[xiv] Given this interpretation of the prior studies and the patient’s response, further rounds of nivolumab were approved. Had the patient not had improvements in the tumor’s size following a round of nivolumab, then pembrolizumab’s prior empirical evidence in isolation would have been insufficient, inductively speaking, to justify his continued use of nivolumab.[xv] The case demonstrates a shift in reasoning from the traditional induction to abduction. The phenomenon of ‘cancer improvement’ is considered causally linked to nivolumab and its underlying physiological mechanisms.[xvi] However, “the weakness of abductions is that there may always be some other better, unknown explanation for an effect. The patient may for example belong to a special subgroup that spontaneously improves, or the change may be a placebo effect. This does not mean, however, that abductive inferences cannot be strong or reasonable, in the sense that they can make a conclusion probable.”[xvii] To demonstrate the limitations of relying on the abductive standard in isolation, commentators have pointed out that side effects in precision medicine are hard to rule out as being related to the initial intervention itself unless trends from a group of patients are taken into consideration.[xviii] As artificial intelligence (AI) assists the development of precision medicine for oncology, this uncertainty ought to be taken into consideration. The implementation of AI has been crucial to the development of precision medicine by providing a way to combine large patient datasets or a single patient with a large number of unique variables with machine learning to recommend matches based on statistics and probability of success upon which practitioners can base medical recommendations.[xix] The AI is usually not establishing a causal relationship[xx] – it is predicting. So, as AI bleeds into medical devices, like brain-computer interfaces, the same cautions about using abductive reasoning alone should be carried over. II. Responsive Neurostimulation, AI, and Personalized Medicine Like precision medicine in cancer treatment, computer-brain interface technology similarly focuses on the individual patient through personalized settings. In order to properly expose the intersection of AI, precision medicine, abductive reasoning, and implantable neurotechnologies, the descriptions of adaptive deep brain stimulation systems need to deepen.[xxi] As a broad summary of adaptive deep brain stimulation, to provide a patient with the therapeutic stimulation, a neural signal, typically referred to as a local field potential,[xxii] must first be detected and then interpreted by the device. The main adaptive deep brain stimulation device with premarket approval, the NeuroPace Responsive Neurostimulation system, is used to treat epilepsy by detecting and storing “programmer-defined phenomena.”[xxiii] Providers can optimize the detection settings of the device to align with the patient’s unique electrographic seizures as well as personalize the reacting stimulation’s parameters.[xxiv] The provider adjusts the technology based on trial and error. One day machine learning algorithms will be able to regularly aid this process in myriad ways, such as by identifying the specific stimulation settings a patient may respond to ahead of time based on their electrophysiological signatures.[xxv] Either way, with AI or programmers, adaptive neurostimulation technologies are individualized and therefore operate in line with precision medicine rather than standard treatments based on large clinical trials. Contemporary neurostimulation devices are not usually sophisticated enough to be prominent in AI discussions where the topics of neural networks, deep learning, generative models, and self-attention dominate the conversation. However, implantable high-density electrocorticography arrays (a much more sensitive version than adaptive deep brain stimulation systems use) have been used in combination with neural networks to help patients with neurologic deficits from a prior stroke “speak” through a virtual avatar.[xxvi] In some experimental situations, algorithms are optimizing stimulation parameters with increasing levels of independence.[xxvii] An example of neurostimulation that is analogous to the use of nivolumab in Norway surrounds a patient in the United States who was experiencing both treatment-resistant OCD and temporal lobe epilepsy.[xxviii]Given the refractory nature of her epilepsy, implantation of an adaptive deep brain stimulation system was indicated. As a form of experimental therapy, her treatment-resistant OCD was also indicated for the off-label use of an adaptive deep brain stimulation set-up. Another deep brain stimulation lead, other than the one implanted for epilepsy, was placed in the patient’s right nucleus accumbens and ventral pallidum region given the correlation these nuclei had with OCD symptoms in prior research. Following this, the patient underwent “1) ambulatory, patient-initiated magnet-swipe storage of data during moments of obsessive thoughts; (2) lab-based, naturalistic provocation of OCD-related distress (naturalistic provocation task); and (3) lab-based, VR [virtual reality] provocation of OCD-related distress (VR provocation task).”[xxix] Such signals were used to identify when to deliver the therapeutic stimulation in order to counter the OCD symptoms. Thankfully, following the procedure and calibration the patient exhibited marked improvements in their OCD symptoms and recently shared her results publicly.[xxx] In both cases, there is a similar level of abductive justification for the efficacy of the delivered therapy. In the case study in which the patient was treated with adaptive deep brain stimulation, they at least had their neural activity tested in various settings to determine the optimum parameters for treatment to avoid them being based on guesswork. Additionally, the adaptive deep brain stimulation lead was already placed before the calibration trials were conducted, meaning that the patient had already taken on the bulk of the procedural risk before the efficacy could be determined. Such an efficacy test could have been replicated in the first patient’s cancer treatment, had it been biopsied and tested against the remaining immunotherapies in vitro. Yet, in the case of cancer with few options, one previous dose of a drug that appeared to work on the patient may justify further doses. However, as the Norwegian case presents, corroboration with known responses to a similar drug (from a clinical trial) could be helpful to validate the treatment strategy. (It should be noted that both patients were resigned to these last resort options regardless of the efficacy of treatment.) There are some elements of inductive logic seen with adaptive deep brain stimulation research in general. For example, abductively the focus could be that patient X’s stimulation parameters are different from patient Y’s and patient Z’s. In contrast, when grouped as subjects who obtained personalized stimulation, patients X, Y, and Z demonstrate an inductive aspect to this approach’s safety and/or efficacy. The OCD case holds plenty of abductive characteristics in line with precision medicine’s approach to treating cancer and as more individuals try the method, there will be additional data. With the gradual integration of AI into brain-computer interfaces in the name of efficacy, this reliance on abduction will continue, if not grow, over time. Moving forward, if a responsive deep brain stimulation treatment is novel and individualized (like the dose of nivolumab) and there is some other suggestion of efficacy (like clinical similarities to other patients in the literature), then it may justify insurance coverage for the investigative intervention, absent other unrelated reasons to deny it. III. Ethical Implications and Next Steps While AI’s use in oncology and neurology is not yet as prominent as its use in other fields (e.g., radiology), it appears to be on the horizon for both.[xxxi] AI can be found in both the functioning of the neurotechnologies as well as the implementation of precision medicine. The increasing use of AI may serve to further individualize both oncologic and neurological therapies. Given these implications and the handful of publications cited in this article, it is important to have a nuanced evaluation of how these treatments, which heavily rely on abductive justification, ought to be managed. The just use an abductive approach may be difficult as AI infused precision medicine is further pursued. At baseline, such technology relies on a level of advanced technology literacy among the general public and could exclude populations who lack access to basic technological infrastructure or know-how from participation.[xxxii] Even among nations with adequate infrastructure, as more patients seek out implantable neurotechnologies, which require robust healthcare resources, the market will favor patient populations that can afford this complex care.[xxxiii] If patients already have the means to pay for an initial dose/use of a precision medicine product out of pocket, should insurance providers be required to cover subsequent treatments?[xxxiv] That is, if a first dose of a cancer drug or a deep brain stimulator over its initial battery life is successful, patients may feel justified in having the costs of further treatments covered. The Norwegian patient’s experience implies there is a precedent for the idea that some public insurance companies ought to cover successful cancer therapies, however, insurance companies may not all see themselves as obligated to cover neurotechnologies that rely on personalized settings or that are based on precision/abductive research more than on clinical trials. CONCLUSION The fact that the cases outlined above rely on abductive style of reasoning implies that there may not be as strong a justification for coverage by insurance, as they are both experimental and individualized, when compared to the more traditional large clinical trials in which groups have the same or a standardized protocol (settings/doses). If a study is examining the efficacy of a treatment with a large cohort of patients or with different experimental groups/phases, insurance companies may conclude that the resulting symptom improvements are more likely to be coming from the devices themselves. A preference for inductive justification may take priority when ruling in favor of funding someone’s continued use of an implantable neurostimulator. There are further nuances to this discussion surrounding the classifications of these interventions as research versus clinical care that warrant future exploration, since such a distinction is more of a scale[xxxv] than binary and could have significant impacts on the “right-to-try” approach to experimental therapies in the United States.[xxxvi] Namely, given the inherent limitations of conducting large cohort trials for deep brain stimulation interventions on patients with neuropsychiatric disorders, surgically innovative frameworks that blend abductive and inductive methodologies, like with sham stimulation phases, have traditionally been used.[xxxvii] Similarly, for adaptive brain-computer interface systems, if there are no large clinical trials and instead only publications that demonstrate that something similar worked for someone else, then, in addition to the evidence that the first treatment/dose worked for the patient in question, the balance of reasoning would be valid and arguably justify insurance coverage. As precision approaches to neurotechnology become more common, frameworks for evaluating efficacy will be crucial both for insurance coverage and for clinical decision making.

Chapters 12 and 13 of the De Interpretations present some puzzles, which it is my purpose to try to solve. The latest commentator, Professor Jaakke Hintikka, attempts in Acta Philosophica Fennica xiv, 5–22, to abolish the difficulties by taking certain verbs in an unusual way. He suggests that in these chapters, which is usually taken to denote logical consequence, sometimes expresses simply compatibility, sometimes equivalence, and that at 22a38ff., 22b3O, and 23a17, which again is usually taken to denote consequence, in (...) fact expresses compatibility. I propose to counter Hintikka's arguments and to maintain that both verbs express consequence; but as my main purpose is to give my own explanation of the general trend of Aristotle's remarks, I shall take the passages discussed by Hintikka in the order in which they occur in Aristotle's text.

In lieu of an abstract, here is a brief excerpt of the content:Reviews 91 THE ROOTS OF MODERN LOGIC ALASDAIR URQUHART Philosophy/ U. ofToronto Toronro, ON, Canada M5S IAI [email protected] I. Grattan-Guinness. The Searchfor Mathematical Roots,r870--r940: logics, Set Theoriesand the Foundations of Mathematicsfrom Cantor through Russellto Godel Princeron: Princeton U. P.,2000. Pp. xiv,690. us$45.oo. Grattan-Guinness's new hisrory of logic is a welcome addition to the literature. The title does not quite do justice ro the book, since it begins with the (...) prehistory of English work in algebraic logic, including the work of the French analycicalschool, and extends to just after Godel's great incompleteness paper of 1931.The core of the book, though, is the philosophical and mathematical developmems leading up to and immediately following from chework ofWhicehead and Russell.Russell is ac chehearcof che book, and as a whole che hisrory forms an imporranr conrribucion ro Russell scudies. Commemarors on Russell have often confined themselves to a rather narrow hisrorical perspeccivein which Russell is seen as the (problemacic) heir of Gottlob Frege, and few ocher hisrorical figures (ocher than Peano) emer imo che picture. Graccan-Guinness corrects chis hisrorica.limbalance by placing Russell in che mucl1 wider context of the development of machemacics on che continent, and in parricu.laremphasizing strongly che key influence of Camor on 92 Reviews Russell's work. Cantor has usually received short shrift from philosophers, as unlike Frege,he appears rarher naive from rhe philosophical point of view. The story proper begins in Chaprer 2 wirh L-igrange'sversion of analysis in which rhe basic concepts were to be defined in rerms of algebraic manipularion of power series. This lead to rhe founding of rhe Analyrical Socierywhere Babbage, Herschel and Peacock were active. It is in chis English tradicion of algebraic analysis char rhe pioneering work of De Morgan and Boole found irs roors. Grarran-Guinness givesa derailed account of the work of both logicians, although his discussion of Boole's merhods does not seem entirely adequate. The question is:what are we to make of Boole'spuzzling insistence chat expressions like x + y are "uninterpretable", while he nevertheless manipulated them freely in his mathematical derivations? It is not correct to say that the addition sign can only link disjoint class symbols, since ir is belied by Boole's formal pracrice. A possible solution has been suggested by Hailperin, in his book on Boole's logic, in which he proposes interpreting the "uninterpretable" expressions as denoting signed mulrisets. Oddly, Grattan-Guinness refers to Hailperin 's work,' bur elsewhere (p. 42) adopts rhe view that Boole's addition sign could only link disjoint classes.The chapter concludes with brief accounts of the work of Cauchy, Weierstrass and Bolz.'lno. The next chapter is a detailed account of rhe work of Cantor and his creation of Mengenlehre. The origins of set theory in the theory of trigonometrical series, and rhe ensuing discoveryof rransfinire ordinal and cardinal numbers, are described clearly and succinctly. In addition, the chapter contains an account of Dedekind's philosophy of arithmetic and Cantor's philosophy of mathematics. Cantor's philosophy is an uneasy blend of formalism, platonism and idealism, and has tmderstandably aroused little enthusiasm among philosophers of matl1ematics, alrhough Michael Hallerr has recently smdied it in detail. GrammGuinness emphasizes, rhough, Cantor's magnificent marhematica.l achievements, in defining and clarifying basic conceprs such as measure, dimension and cardinality of sets. Chaprer 4 is a rather miscellaneous chapter, in which six partly independent, partly interrwined stories are told. It begins with developments in sectheory in Germany and France up to the turn of rhe century, goes on to discuss American logic in rhe work of C. S. Peirce and his students, and continues the rheme of algebraic logic with Schroder and his logic of relatives. The remainder of the chapter is given over to Frege, Husserl and Hilbert. The section on Frege is one of rhe more idiosyncratic parts of the book. Grattan-Guinness distinguishes berween Frege, "a mathematician who wrore in ' T Hailperin, Book's logic and Probability, 2nd ed. (Amsterdam: North-Holland, 1986).

In this first part of a two-part paper, we describe efforts in the early decades of this century to restrict the extent of violations of the Second Law of thermodynamics that were brought to light by the rise of the kinetic theory and the identification of fluctuation phenomena. We show how these efforts mutated into Szilard’s proposal that Maxwell’s Demon is exorcised by proper attention to the entropy costs associated with the Demon’s memory and information acquisition. In the second part (...) we will argue that the information theoretic exorcisms of the Demon provide largely illusory benefits. According to the case, they either return a presupposition that can be had without information theoretic consideration or they postulate a broader connection between information and entropy than can be sustained.

This essay is the first act of a two-act play. My ultimate aim is to defend a simple proposition: time passes. To be more precise, I want to defend the claim that the passage of time is an intrinsic asymmetry in the structure of space-time itself, an asymmetry that has no spatial counterpart and is metaphysically independent of the material contents of space-time. It is independent, for example, of the entropy gradient of the universe. This view is part of common-sense, (...) but has been widely attacked by philosophers. The passage of time, we are told, is a myth, an illusion, even an incoherent notion. Because the notion that time passes is common sense, it perhaps requires little positive defence; if there are no weighty objections to the view, it ought to be accepted. So the first, and more important, act of the play is defusing the arguments which have been used to cast doubt on the passage of time. I have positive arguments to give, but not having space for them here, I will confine myself to an examination of the common philosophical arguments that have been used to cast doubt on the passage of time.

I defend an account of sexual orientation, understood as a reflexive disposition to be sexually attracted to people of a particular biological Sex or Sexes. An orientation is identified in terms of two aspects: the Sex of the subject who has the disposition, and whether that Sex is the same as, or different to, the Sex to which the subject is disposed to be attracted. I explore this account in some detail and defend it from several challenges. In doing so, (...) I provide a theoretical framework that justifies our continued reference to Sex-directed sexual orientation as an important means of classifying human subjects. (shrink)

In this paper, I have been able to demonstrate that the so-called Lexicon Theeteti is an apographon of Pal. gr. 173, a well known Plato's manuscript of Xth century. The codex Laurentianus 57,24, which contains the lexicon, previously dated to XIV/XV century, was also backdated to the first half of XIVth century.

I know that the laptop on which I am writing these words is dusty. How do I know? I can see that it is dusty. Seeing that it is dusty is a way of knowing that it is dusty. How come? According to what I’m going to call the entailment view, ‘S sees that P’ entails ‘S knows that P’ and it is only because this is so that seeing that the laptop is dusty qualifies as a way of knowing (...) that it is dusty. Generalizing from this, the entailment view concludes that Φ-ing that P is a way of knowing that P if and only if ‘S Φs that P’ entails ‘S knows that P’. (shrink)

In what follows, I attempt to reconstruct Fichte’s and Hegel’s reasons for developing at almost the same time two very different conceptions of a rational economic order. Whereas Hegel, on the basis of his objective notion of reason, would recommend that a rational state, founded on the notion of right, should include a strictly confined, socially embedded market economy, Fichte, on the basis of his subjective notion of reason, thought instead that the very same state must adopt an economic order (...) that might well be described as a ‘planned economy’. Throughout the article I discuss whether it is the stark differences in their methodological premisses or their very different ideas about the individual freedom to be institutionalized in the economic sphere that helps us understand their respective notions of a rational economy.
