We introduce a multimodal logic for order of magnitude reasoning which considers a new logic-based alternative to the notion of closeness, we provide an axiom system and prove its soundness and completeness.

In this paper, we focus on a logical approach to the important notion of closeness, which has not received much attention in the literature. Our notion of closeness is based on the so-called proximity intervals, which will be used to decide the elements that are close to each other. Some of the intuitions of this definition are explained on the basis of examples. We prove the decidability of the recently introduced multimodal logic for closeness and, then, we show some capabilities (...) of the logic with respect to expressivity in order to denote particular positions of the proximity intervals.

Combining modalities has proven to have interesting applications and many approaches that combine time with other types of modalities have been developed. One of these approaches uses accessibility functions between flows of time to study the basic properties of the functions, such as being total or partial, injective, surjective, etc. The completeness of certain systems expressing many of these properties, with the exception of surjectivity, has been proven. In this paper we propose a language with nominals to denote the initial (...) and final sets of each function in a model in order to obtain a complete system for reasoning about surjective partial functions.

ABSTRACT In this paper we present a new semantic approach for propositional linear temporal logic with discrete time, strongly based in the well-order of IN (the set of natural numbers). We consider temporal connectives which express precedence, posteriority and simultaneity, and they provide a family of expressively complete temporal logics. The selection of the new semantics and connectives used in this work was principally to obtain a suitable executable temporal logic, which can be used for the specification and control of (...) process behaviour in discrete time in a similar way to thai presented by D. Gabbay in [GAB 89], Our new approach has two advantages: firstly, the connectives are defined intuitively so that they have interpretations which relate to properties of interest in real systems; secondly, it provides a new semantics that facilitates simpler proofs of many valid formulas and metatheorems. To confirm this second advantage, we use our semantics to give a formal proof of the Separation Theorem for one of these logics (specifically LN3). The great interest of this Separation Theorem for the executable temporal logic is emphasised by D. Gabbay in [GAB 89], [GAB 88]. (shrink)

In previous works, we presented a modification of the usual possible world semantics by introducing an independent temporal structure in each world and using accessibility functions to represent the relation among them. Different properties ofthe accessibility functions have been considered and axiomatic systems which define these properties have been given. Only a few ofthese systems have been proved tobe complete. The aim ofthis paper is to make a progress in the study ofcompleteness for functional systems. For this end, we use (...) indexes as names for temporal flows and give new proofs of completeness. Specifically, we focus our attention on the system which defines injectivity, because the system which defines this property without using indexes was proved to be incomplete in previous works. The only system considered which remains incomplete is the one which defines surjectivity, even ifwe consider a sequence ofnatural extensions ofthe previous one. (shrink)

Argument evaluation, one of the central problems in argumentation theory, consists in studying what makes an argument a good one. This paper proposes a formal approach to argument evaluation from the perspective of justification logic. We adopt a multi-agent setting, accepting the intuitive idea that arguments are always evaluated by someone. Two general restrictions are imposed on our analysis: non-deductive arguments are left out and the goal of argument evaluation is fixed: supporting a given proposition. Methodologically, our approach uses several (...) existing tools borrowed from justification logic, awareness logic, doxastic logic and logics for belief dependence. We start by introducing a basic logic for argument evaluation, where a list of argumentative and doxastic notions can be expressed. Later on, we discuss how to capture the mentioned form of argument evaluation by defining a preference operator in the object language. The intuitive picture behind this definition is that, when assessing a couple of arguments, the agent puts them to a test consisting of several criteria. As a result of this process, a preference relation among the evaluated arguments is established by the agent. After showing that this operator suffers a special form of logical omniscience, called preferential omniscience, we discuss how to define an explicit version of it, more suitable to deal with non-ideal agents. The present work exploits the formal notion of awareness in order to model several informal phenomena: awareness of sentences, availability of arguments and communication between agents and external sources. We discuss several extensions of the basic logic and offer completeness and decidability results for all of them. (shrink)

Se trata de un número monográfico muy interesante, que integra un conjunto de trabajos de prestigiosos profesores universitarios—A. Clark, H. Simon, A. Gomila, J. Toribio, R. Tuomela, M. Liz, P.F. Martínez Freire, F. Broncano, C.J. Moya, P.S. Churchland, P.M. Churchland, A. Burrieza y A. Estany—sobre diversos temas candentes de la Filosofía de las Ciencias Cognitivas: cognición incorporizada, teorías computacionales de la cognición, mecanismos mentales de la intersubjetividad, responsabilidad semántica, intención conjunta y colectiva, relación entre el problema del mundo externo (...) y el problema ontológico de la experiencia subjetiva, la realidad desde la mente, relevancia filosófica de una teoría funcional de las emociones, problemas que plantean las emociones a la posibilidad de responsabilidad moral, neurobiología y conciencia, neurobiología cognitiva de las virtudes morales, tratamiento lógico de la conciencia en Inteligencia Artificial y ventajas epistémicas de la cognición socialmente distribuida. El agrupamiento de los artículos en partes diferenciadas es adecuado y coherente. Me habría gustado mucho seguirlo con orden y analizar sus contenidos con detalle; pero debo limitarme a un examen más general y a considerar simplemente las grandes tendencias o afinidades temáticas que se manifiestan a través de las páginas. Quizás lo más relevante sea la constatación efectiva de un fenómeno que se ha producido en la investigación actual sobre ciencias cognitivas y que señala A. Clark en su escrito: el redescubrimiento del cuerpo y el mundo, la crisis de una visión aislacionista de la cognición, y el surgimiento de un nuevo paradigma de patrones de actividad distribuidos a lo largo de trayectorias de procesamiento temporalmente extendidas mediante redes neuronales recurrentes. Se aprecia aquí que el énfasis se ha trasladado desde la representación simbólica hacia series reiteradas de interacciones agente-entorno. Y eso es lo prime-ro que cabría resaltar: el paulatino abandono del paradigma de representación simbólica y la atención creciente a las interacciones acopladas agente-mundo. (shrink)

Treatise on Yoga philosophy; Sanskrit text with Hindi commentary and translation.

One of the major problems in contemporary philosophy of mind is the dualism of first-person and third-person perspectives — the question of whether conscious experience is public and epistemically accessible or private and qualitative. Recognising the relevance of the arguments of both sides, naturalists and anti-naturalists, I attempt to resolve this dichotomy using Bruno Latour’s methodology on the theories of Immanuel Kant and Moritz Schlick. To do so, I propose not to reduce the theory of consciousness to one interpretation, but (...) to consider conscious experience as a “boundary object” between the spheres of the private and the public, the accessible and the qualitative, the unique and the reproducible. Through the “practice of translation” I demonstrate the failure of ontologies of conscious experience proposed by both naturalism and anti-naturalism, and propose an “intersectional theory” as an alternative theory of conscious experience that affirms, on the one hand, the uniqueness of the individual’s epistemic position and, on the other hand, its reproducibility and communicability. I introduce the term “intersectional locality” to denote the ontological status of conscious experience. In the next step, I return to the necessary (according to Latour) “practice of purification” of those epistemic zones whose fusion was outlined earlier, which allows me to recognise the intuition behind the dichotomy of the two perspectives as legitimate and requiring conceptualisation. The mediation of Schlick’s positivist theory and Kant’s transcendentalist theory allows us to present first-person and third-person perspectives as two epistemic registers, subordinated to the position of a historically specific conscious subject. I treat the first-person perspective as a reflective power of judgment, and the third-person perspective as a determinative power of judgment; doing so, I establish the connection between the qualitative interpretation of phenomenal experience and the aesthetic principle of the reflective power of judgment. I conclude that conscious experience as a subject matter of research is a hybrid object, and only the project of “nonmodern” science will make it possible to create a relevant theory of consciousness that does not resort to reduction.

In lieu of an abstract, here is a brief excerpt of the content:570 BOOK REVIEWS like reasonable rule for economic life. This effort is worthy of more attention than is possible here, but let it be noted that it must inevitably suffer the same fate as any ethical calculus: someone must decide for others what is their due and what is not. How much wealth, for example, makes for a concentration [of wealth] that would be " demonstrably detrimental to some (...) people's exercise of their generic rights "? His is ultimately an entitlement or rights ethic, rather than an aitial ethic of goal-purposive fulfillment for the individual, projected outwards for a common good scenario. While his rejection of goal ethics's inability to detail principles for distribution of goods is noteworthy, it does not appear that a tightened version of generic rights theory will come closer to either of Phillips's desiderata: a justification of moral reasoning apart from any theory of nature or a calculus for its application. Desan and Phillips wish to think against the limits of the human situation. For Desan, rising above limitation is a moral task and obligation facing us each, if there is to be a common future. His call is to be World Citizen in a Polis of Nations. Phillips's vision is more concrete, a distribution of benefits to benefit all with well-being and freedom. But this mundane task is no less difficult than Desan's transcendent one. Indeed, according to Augustine, even the Divine Mind must utilize an artifice in dealing with human creation: "He loves each of us as though there were only one of us." Both ethicists have striven to show us how we might think this vision for ourselves, i.e., for each other of us. ]OIIN B. DAVIS, O.P.

Even to list the changes and events which occurred in seventeenth century England is a difficult task: the century spans the period from the death of Queen Elizabeth to the Glorious Revolution and beyond, through the Civil War, the accession and exile (twice) of the Stuarts, the rise of science, the transformation of the theological and religious issues of the English Reformation, to name only the most obvious. To conceive a book, in the form of occasional essays, which not only addresses these changes and events but does so by establishing the connections which were present with European currents at the same time surely tempts fate, even when it does not tempt reviewers. BOOK REVIEWS 571 But Hugh Trevor-Roper is a master, both of the period under survey and of the form of the essay. With one exception, each of these essays began as a lecture or seminar paper, and the pleasantly legible style in which they are written must bear some trace of that origin. The occasional flashes of wit, mixed with rthe fairly non-technical style, make the book a joy to read and a welcome escape from the usually constipated style of scholarly prose. In his Introduction, the essayist clearly sets forth his thesis that English intellectual history does not exist apart from the currents of European intellectual history (a thesis for which Trevor-Roper has already staked a claim). That leads to what may very well be the major problem with these essays: its end is in its beginning. The list of names cited in these essays only partially coincides with the list of names in the index; the former is much longer than the latter. And while the style of the essay welcomes the reader to the period, it also throws up more names and places and events than can be explained or even annotated adequately. This occurs both on a large and on a small scale. The first essay, on "Nicholas Hill, the English Atomist" contains such a vast array of names that at times it becomes the prosopo· graphical equivalent of a telephone book. On a large scale, there is the problem with a definition of Arminianism. No definition, at least no formal definition, is attempted-and this is probably wise. But, particularly in... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS Galileo: For Copemicanism and for the Church. By ANNIBALE FANTOLI. Translated by George V. Coyne, S.J. Studi Galileiani Vol. 3. Vatican City: Vatican Observatory Publications, 1994. Distributed by the University of Notre Dame Press, Notre Dame, Indiana. Pp. xix+ 540. $21.95 (paper). This exhaustive treatment of Galileo and his relationship to the Church was first published in Italian by the Vatican Observatory in 1993 as Vol. 2 (...) of its Studi Galileiani series, bearing the title Galileo: Per il Copemicanesimo e per la Chiesa. So excellent was the study that Father George Coyne, the director of the Vatican Observatory, took it on himself personally to translate the volume into English. Although not a member of the Galileo Commission set up by Pope John Paul II to review the Galileo case, as were Coyne and myself, Fantoli has admirably complemented the work of the Commission and his book surely belongs in the Studi Galileiani collection. A former Jesuit with degrees in mathematics and physics, Fantoli began the book more than twenty-five years ago when he was preparing a course on Galileo at Sophia University in Tokyo. His intention was to show that for Galileo it was never a question of choosing between Copernicanism and the Church, and that the saddest drama of his life was being faced with an injunction that forced him to befor the Church and against Copemicanism. The subtitle of his book proclaims Galileo's true intentions, despite his failure to convince others that this was what his life was all about. A great strength of Fantoli's treatment is its documentation, which abounds in excerpts from Galileo's writings and his correspondence as found in the National Edition of his works and also in citations from new materials that have been uncovered by the Galileo Commission. Thanks to Coyne, all of these texts, many of which were hitherto available only in Latin or Italian, can now be easily accessed in English translation. Another strength of Fantoli's work is that he has kept abreast of Galileo literature over the years and thus is able to offer scholarly critiques of authors whose works exhibit a bias against the Church. Especially welcome are his careful discussions of the positions of earlier writers such as Giorgio de Santillana, Ludovico Geymonat, and Stillman Drake, as well as those of more recent authors, Mario Biagioli, Maurice Finocchiaro, Pietro Redondi, William R. Shea, and Richard S. Westfall. The book is a tour de force and there is little to criticize in it. Unfortunately, however, a typesetting error at its very beginning might create 317 318 BOOK REVIEWS the wrong impression and throw off prospective readers. About six lines of text were omitted at the bottom of page 9. To remedy this the following words should be inserted between the end of page 9 and the beginning of page 10: confused with the Sun) which had heen worked out by Philolaus (about 475 B.C.) within the context of the Pythagorean school.9 In a further modification of this theory the central fire as well as the hypothesis of an anti-earth were done away with, which left the earth at the center of the universe. To offset this addition, the last six lines on the bottom of page 10 should be deleted, for these lines are repeated at the top of page 11. Otherwise, with this change, the exposition reads correctly. The remaining typographical errors are few and in no case do they affect the sense. After a brief introduction in which he presents the astronomical concepts necessary for understanding the details of the Copernican debate, Fantoli divides his treatment into seven chapters. The first two of these are devoted to Galileo's early life and teaching at the Universities of Pisa and Padua, his perfection of the telescope, and the beginnings of the controversies about the earth's motion that were provoked by his telescopic discoveries, The next three chapters then take up the scriptural arguments in detail, Galileo's battle with the Jesuits over the comets of 1618 and his The Assayer of 1623, and his resumption of the Copernican program with the publication of his Dialogue...

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. My last two volumes, in press at the same time as McMullin's Aquinas Lecture, answer in detail the aporiai he there raises.1 I need 1 Galileo's Logic of Discovery and Proof.

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)

The constitutional monarchy of present-day Britain hardly seems the same sort of institution as fourteenth-century feudal kingdoms, but Dante’s Monarchia (c. 1313) and Walter Bagehot’s The English Constitution (1872) share fundamental assumptions about what the purpose and strengths of monarchy are. In the Monarchia, Dante lays out the essential attributes of monarchy that endure even today: authority, impartiality, and unity. Dante values and promotes monarchy as final arbiter of conflicts, sole just judge without cupidity, and unifying will. More than 550 (...) years later, Bagehot, despite his distrust concerning the Crown’s actual effectiveness, conceives of monarchy in surprisingly similar terms. The monarch is ‘the regulating wheel of our Constitution’, an authority outside and above partisan politics, and the ‘dignified’, ‘intelligible’, unifying element of government. In both cases, the monarch functions as the government’s source of impartial, unifying authority – whether monarch or Parliament ultimately wields that authority. The broad outlines of monarchy are surprisingly similar for both writers, suggesting a basic continuity in the conceptualization of monarchy from the fourteenth to the nineteenth century (and beyond) and an abiding store of reserve symbolism within the monarchic concept that writers, thinkers, and politicians throughout those centuries are able to tap at will.

The grammatical manipulation and production of language is a great deceiver. We have become habituated to accept the use of well-constructed language to indicate intelligence, understanding and, consequently, intention, whether conscious or unconscious. But we are not always right to do so, and certainly not in the case of large language models (LLMs) like ChapGPT, GPT-4, LLaMA, and Google Bard. This is a perennial problem, but when one understands why it occurs, it ceases to be surprising that it so stubbornly (...) persists. This paper will have three main sections. In the Introduction I will say a little about language, its aetiology, and useful sub-divisions into natural and cultural. In the second section I will explain the current situation with regard to large language models and fill in the background debates which set the problem up as one of increased complexity rather than one of a qualitatively different kind from narrow or specific AI. In the third section I will present the case for the missing phenomenological background and why it is necessary for the co-creation of shared meaning in both natural and cultural language, and I will conclude this section by presenting a rationale for why this situation arises and will continue to arise. Before we do any of this, I need to clarify one point: I do not wish to challenge the ascription of artificial general intelligence (AGI) to LLMs, indeed I think agnosticism is best in this respect, but I do challenge the more serious, and erroneous, ascription of understanding, intention, reason, and consciousness to them. And so, I am making two points: an epistemological one about why we fall into error in our ascription of a mental life to LLMs, and an ontological one about the impossibility of LLMs being or becoming conscious.

A growing body of literature has engaged with mass incarceration as a public health problem. This article reviews some of that literature, illustrating why and how bioethicists can and should engage with the problem of mass incarceration as a remediable cause of health inequities. “Mass incarceration” refers to a phenomenon that emerged in the United States fifty years ago: imprisoning a vastly larger proportion of the population than peer countries do, with a greatly disproportionate number of incarcerated people being members (...) of marginalized racial and ethnic groups. Bioethicists have long engaged with questions of health justice for incarcerated people, including consent issues for those participating in research and access to health care. This article provides an overview of the individual and public health impacts of mass incarceration. The article argues that mass incarceration is a bioethics issue that should be addressed in medical education, identifies opportunities for bioethicists to guide hospitals’ interactions with law enforcement officials, and calls on bioethicists to be in conversation with medical and nursing students and health care professionals about these groups’ advocacy efforts concerning structural racism, police violence, and mass incarceration.

‘Rights and Territories: A Reply to Nine, Miller, and Stilz’ defends the Lockean theory of states’ territorial rights (as this theory was presented in Boundaries of Authority) against the critiques of Nine, Miller, and Stilz. In response to Nine’s concern that such a Lockean theory cannot justify the right of legitimate states to exclude aliens, it is argued that a consent-based theory like the Lockean one is flexible enough to justify a wide range of possible incidents of territorial rights – (...) importantly including, though not necessarily including, the sort of right to exclude aliens that is familiar from actual political practice. Miller’s criticisms are more wide-ranging. In response, the article argues that Lockean labor-based property rights are both stronger and more enduring than Miller suggests and that nationalism’s resources for dealing with concerns about rights-supersession and trapped minorities are importantly overstated by Miller. Against Stilz’s Kantian, ‘presentist’ account of states’ authority over persons and territories, it is argued that the rectification of past (historical) wrongs remains morally crucial even in the context of otherwise-just societies and that Stilz’s Kantian/rawlsian position unconvincingly privileges the rights to autonomy of territorially concentrated groups over those of dissenting individuals or wrongfully dispersed groups.

Although Sibawayh dealt with it in a scattered manner under different headings there have been different views on na't (adjective), which is gene-rally included in the tawabi group in Arabic syntax, and there have been debates around these views. Na't, which is categorized as a proper adjective and qualifies the meaning of man'ut (mawsuf), has different characteristics from the sentence elements that indicate the subject. Nahiv scholars have mostly divided na't into two parts: real and causal na't, and they have (...) formulated certain rules for these two parts in accordance with the structure of the Arabic language. Since na't and man'ut are accepted as nouns, the i'rab of na't is subject to men'ut. However, some examples in the Qur'an and some expressions used by the Arabs caused objections to the i'rab of na't being the same as men'ut. It is observed that these objected examples are the cases where men'ut is known and the exceptional cases of madih, zam and jarri jivar. It is also obligatory for the na't to conform to the man'ut in terms of ma'rifiyyah, nekiriyyah, custom and gender. While Sibawayh (d. 180/796) considered it qabh (ugly) for non-propositional words to be na't, scholars such as Ibn Hisham (d. 218/833), Ibn al-Ḥajib (d. 646/1249), and Abd ar-Rahman Jami (d. 898/1492) accepted that na't could be either propositional or non-propositional and cited many examples of na't in the case of non-propositional words. Scholars such as Ibn Jinni (d. 392/1002) and Ibn al-Hajib gave an explanation of the causative na't without naming it, scholars such as Ebu’l-Bekā al-Ukbari (d. 616/1219) analyzed the subject under the title of causative adjective or causative na't, and Halid b. Abdullah al-Azhari discussed it under the title of al-wasf al-majazi. The subject of our study is to examine the handling of na't, which is one of the sentence elements in the Arabic language, in the works written on the field, its parts, the dimension that affects the meaning and the controversial aspects. The aim of the research is to examine the rules that Sibawayh deals with in his al-Kitâb on na'ta and the objections of later Arab linguists to these rules, and to contribute to the field by revealing different views on the subject.

This article aims to offer a fresh analysis of two passages in the extensive necromancy episode in Lucan's Bellum Ciuile: the ritual to reanimate the dead soldier's corpse (6.667–73), and the surgical procedure Erichtho then proceeds to undertake (6.750–7), resembling the practice of a vivisection. The study will focus mostly on the strong connection of magic to medical traditions in antiquity, with a commentary on, and analysis of, these verses through the lenses of medical vocabulary, themes and motifs. It ultimately (...) concludes that Lucan was familiar with the language and characteristics of the medical tradition, enriched his report with them, and was playing with his audience's knowledge of the same.

This paper is devoted to computer modelling of the development and regeneration of multicellular biological structures. Some species are able to regenerate parts of their body after amputation damage, but the global rules governing cooperative cell behaviour during morphogenesis are not known. Here, we consider a simplified model organism, which consists of tissues formed around special cells that can be interpreted as stem cells. We assume that stem cells communicate with each other by a set of signals, and that the (...) values of these signals depend on the distance between cells. Thus the signal distribution characterizes location of stem cells. If the signal distribution is changed, then the difference between the initial and the current signal distribution affects the behaviour of stem cells—e.g. as a result of an amputation of a part of tissue the signal distribution changes which stimulates stem cells to migrate to new locations, appropriate for regeneration of the proper pattern. Moreover, as stem cells divide and form tissues around them, they control the form and the size of regenerating tissues. This two-level organization of the model organism, with global regulation of stem cells and local regulation of tissues, allows its reproducible development and regeneration. (shrink)

Warne's original study provides an insightful analysis of the role of contemplation and creation in the thought of Josef Pieper, illustrating the importance of this practice to earthly happiness and human flourishing. What is the relationship between creation, contemplation, human flourishing, and moral development? Nathaniel Warne's Josef Pieper on the Spiritual Life offers a sophisticated answer to this question through a systematic analysis of philosopher Josef Pieper's (1904-1997) thought. Warne's examination centers on the role of contemplation and creation in Pieper's (...) thinking, arguing that contemplation of the created order is a key feature of earthly happiness. By emphasizing the importance of contemplation, Pieper illustrates the deep interconnections between ethics, creation, and spirituality. For Warne, to posit a binary between the contemplative life and active life creates a false dichotomy. Following Pieper, Warne claims that theology and spirituality cannot be bracketed from ethics and social action--indeed, our lived experience in the world blurs the lines between these practices. Contemplation and action are closer together than are typically assumed, and both have important implications for both our spiritual development and our engagement with the world around us. Ultimately, Warne's emphasis on creation and contemplation represents an attempt to resist a view of ethics and the spiritual life that is divorced from our environment. In response to this view, Warne argues that we need a renewed sense that creation and place are important for self-understanding. Contemplation of creation is, at bottom, a form of communion with God--we thus need a more robust sense of how ethics and politics are rooted in God's creative action. Taking Pieper as a guide, Warne's study helps to deepen our thinking about these connections. (shrink)

Neuropalliative care developed to address the needs of patients living with life‐limiting neurologic disease. One critical consideration is that disease‐related changes to cognition, communication, and function challenge illness experiences and care practices. We conducted an ethnography to understand neuropalliative care as a phenomenon; how it was experienced, provided, conceptualized. Personhood served as our conceptual framework; with its long philosophical history and important place in nursing theory, we examined the extent to which it captured neuropalliative experiences and concerns. Personhood contextualized complex (...) losses, aligning the impact of functional and relational changes. Cognition, communication, and functional alterations stretched conceptions of personhood, insinuating it can be relational, fluid, adaptive. Although normative conceptions of personhood guided research and decision‐making, ethical considerations suggested personhood could be transformed, remade. We consider the implications of our findings through three themes. First, we examine how literature on illness experience fails to integrate the realities of people living with and dying from neurologic disease; we counter this by interrogating the concept of experience. Second, we turn to Ricoeur's work on recognition to illuminate relational conceptions of personhood to inform care practices. Finally, we reflect on how personhood can bridge the gap left by functional changes, enhance relational engagement, and promote dignity at the end of life. (shrink)

This chapter focuses on the property that excited Kuhn's interest in thought experiments: conflict vagueness. This property often generates inconsistent beliefs but is not itself inconsistency. Although it is absent from most thought experiments, a substantial portion of the most provocative thought experiments do spring from this species of vagueness; for they motivate conceptual reform by touching a nerve of indeterminacy. Hence, study of conflict vagueness reveals the ways thought experiments restructure our conceptual scheme.

This chapter examines the hazards and pseudohazards of thought experiment. It attacks most skepticism about thought experiment as arbitrary. It argues that once the standards that are customary for compasses, stethoscopes, and other testing devices are applied, thought experiments measure up. They should be used as part of a diversified portfolio of techniques. Although all these devices are individually susceptible to abuse, fallacy, and error, they provide a network of cross-checks that make for impressive collective reliability.

This chapter illustrates the power of thought experiments by assembling influential thought experiments from the history of science. It lays out the book's plan to understand philosophical thought experiments by concentrating on their resemblance to scientific relatives. Points of difference between philosophical and scientific thought experiments give a preview of obstacles that must be overcome in the course of the campaign. Naive and sophisticated reservations about the philosophical cases are registered for the same purpose.
