In this paper, we discuss an abductive argument for the existence of God from the experience of awe at natural beauty. If God's creative work is a viable explanation for why we experience awe at natural beauty, and there is no satisfactory naturalistic explanation for the origins of such experiences, then we have defeasible evidence that God exists. To evaluate the argument's tenability, we assess the merits of the two main theocentric frameworks that can be marshaled to answer the question (...) of why human beings experience awe at natural beauty: (1) taking the experience of natural beauty as resulting from God's design intentions and (2) conceiving experiences of natural beauty as religious experiences in themselves. We argue that the presence of phenomenological content the fine-grainedness of which exceeds our descriptive and conceptual capacities is better accounted for by the latter hypothesis: experiencing natural beauty amounts to experiencing divine attributes. We conclude that the argument's theological premise is tenable and, having previously argued for the empirical premise (Porcher & De Luca-Noronha, 2021), we conclude that awe at natural beauty is best explained by the existence of God.

Argentine historiography in general, and the history of the Argentine Left in particular, does not receive the attention it deserves in the Anglo-Saxon academic world, due to linguistic and cultural barriers. In this article, we attempt to review for the English-reading public three recent contributions to the history of Marxism in Argentina (Horacio Tarcus's Marx en la Argentina: Sus primeros lectores obreros, intelectuales y científicos, Hernán Camarero's A la conquista de la clase obrera: Los comunistas y el mundo del trabajo (...) en la Argentina, 1920–1935 and Osvaldo Coggiola's Historia del trotskismo en Argentina y América Latina) covering the entire historical spectrum from the early history of Argentine socialism to the history of the PCA and, finally, to the history of local Trotskyism. We attempt to place these works in the context of Argentine historiography and of the political context in which those books were written. (shrink)

A number of experiences have demonstrated how digital solutions are effective in improving quality of life (QoL) and health outcomes for older adults. Smart Health Age-Friendly Environments (SHAFE) is a new concept introduced in Europe since 2017 that combines the concept of Age-Friendly Environments with Information Technologies, supported by health and community care to improve the health and disease management of older adults and during the life-course. This chapter aims to provide an initial overview of the experiences available not only (...) in Europe, based on the research work of the participants of the International Interdisciplinary Network on Health and Well-being in an Age-Friendly Digital World (NET4Age-Friendly), which could be of interest to preventive, health and social authorities. The chapter reports good practices, pain points, and bottlenecks that may require a collaborative, interdisciplinary research approach to facilitate the transformations towards smart, sustainable, health and age-friendly cities and communities.

The aim of this paper is twofold: First, we present and develop a system of logic for pragmatics including the act of denial. Second, we analyse in our framework the so-called paradox of assertability. We show that it is possible to yield sentences that are not assertable. Moreover, under certain conditions, a symmetric result can be obtained: There is a specular paradox of deniability. However, this paradox is based on the problematic principle of classical denial equivalence.

Following the speech act theory, we take hypotheses and assertions as linguistic acts with different illocutionary forces. We assume that a hypothesis is justified if there is at least a scintilla of evidence for the truth of its propositional content, while an assertion is justified when there is conclusive evidence that its propositional content is true. Here we extend the logical treatment for assertions given by Dalla Pozza and Garola by outlining a pragmatic logic for assertions and hypotheses. On the (...) basis of this extension we analyse the standard logical opposition relations for assertions and hypotheses. We formulate a pragmatic square of oppositions for assertions and a hexagon of oppositions for hypotheses. Finally, we give a mixed hexagon of oppositions to point out the opposition relations for assertions and hypotheses. (shrink)

Technological innovation is almost always investigated from an economic perspective; with few exceptions, the specific technological and social nature of innovation is often ignored. We argue that a novel way to characterise and make sense of different types of technological innovation is to start considering uncertainty. This seems plausible since technological development and innovation almost always occur under conditions of uncertainty. We rely on the distinction between, on the one hand, uncertainty that can be quantified (e.g. probabilistic risk) and, on (...) the other, deep forms of uncertainty that may resist the possibility of being quantified (e.g. severe or fundamental uncertainties). On the basis of these different ingredients of uncertainty in technological innovation, we propose a new taxonomy that reveals the technological nature of innovation. Unlike previous taxonomies employed to handle different types of technological innovations, our taxonomy does not consider the economic value of innovation alone; it is much more oriented towards societal preferences and forms of technological uncertainty. Finally, we investigate the coherence of our proposal with the dual nature of technological artefacts, showing that innovation can be grounded on structural and functional factors and not just on economic ones.

Ambiguity occurs insofar as a reasoner lacks information about the relevant physical probabilities. There are objections to the application of standard Bayesian inductive logic and decision theory in contexts of significant ambiguity. A variety of alternative frameworks for reasoning under ambiguity have been proposed. Two of the most prominent are Imprecise Bayesianism and Dempster–Shafer theory. We compare these inductive logics with respect to the Ambiguity Dilemma, which is a problem that has been raised for Imprecise Bayesianism. We develop an agent-based (...) model comparison that isolates the difference between the two inductive logics in their updating methods. We find that Dempster–Shafer theory does not avoid the Ambiguity Dilemma. We discuss the implications of this result. (shrink)

Some Presentists—according to whom everything is present—identify instants of time with propositions of a certain kind. However, the view that times are propositions seems to be at odds with Presentism: if there are times then there are past times, and therefore things that are past; but how could there be things that are past if everything is present? In this paper, we describe the Presentist view that times are propositions ; we set out the argument that Presentism is incompatible with (...) the view that times are propositions ; and then we describe three possible responses to that argument on behalf of Presentists who identify times with propositions. We argue that each of these responses comes with significant costs. Finally, we describe a fourth possible response—according to which times are irreducibly higher-order entities—which appears to avoid the costs of the other three. We also describe and respond to two objections to the higher-order strategy. (shrink)

The goal of this paper is to review and critically discuss the philosophical aspects of probabilistic seismic hazard analysis (PSHA). Given that estimates of seismic hazard are typically riddled with uncertainty, diferent epistemic values (related to the pursuit of scientifc knowledge) compete in the selection of seismic hazard models, in a context infuenced by non-epistemic values (related to practical goals and aims) as well. We frst distinguish between the diferent types of uncertainty in PSHA. We claim that epistemic and nonepistemic (...) considerations are closely related in the selection of the appropriate estimate of seismic hazard by the experts. Finally, we argue that the division of scientifc responsibility among the experts can lead to responsibility gaps. This raises a problem for the ownership of the results (“no one’s model” problem) similar to the “problem of many hands” in the ethics of technology. We conclude with a plea for a close collaboration between philosophy and engineering. (shrink)

A thorough understanding of what needs are is fundamental for design- ing well-behaved information systems for many social applications and in partic- ular for public services. Talking about needs pervades indeed the jargon of Public Administrations when motivating their service offering. In this paper, we propose an ontological analysis of needs, aiming at a principled disentangling of the differ- ent uses of the term. We leverage philosophical tradition on intentionality, for its rich understanding of mental entities, we compare it with (...) the well-established BDI (Belief-Desire-Intention) tradition in knowledge representation, and we propose a formalisation of needs within the foundational ontology DOLCE. Throughout the paper, we motivate our analysis focusing on needs in public services. (shrink)

Human behavior and thought often exhibit a familiar pattern of within group similarity and between group difference. Many of these patterns are attributed to cultural differences. For much of the history of its investigation into behavior and thought, however, cognitive science has been disproportionately focused on uncovering and explaining the more universal features of human minds—or the universal features of minds in general. -/- This entry charts out the ways in which this has changed over recent decades. It sketches the (...) motivation behind the cultural turn in cognitive science, and situates some of its central findings with respect to the questions that animate it and the debates that it has inspired. Woven throughout the entry are examples of how the cognitive science of culture, and especially its elevated concern with different forms of diversity and variation, continues to influence and be influenced by philosophers. -/- One cluster of philosophical work falls within the traditional subject matter of philosophy of science, in this case of the cognitive and social sciences. Philosophers have analyzed and assessed the methods and evidence central to the scientific study of cognition and culture, and have offered conceptual scrutiny, clarification, and synthesis. Research in a second vein sees philosophers themselves contributing more directly to cognitive scientific projects, (co)constructing theories, helping build computational models, even gathering empirical data. A third kind of work is naturalistic philosophy or philosophy of nature, wherein philosophers seek to use results from the cognitive science of culture to inform or transform debates over long-standing philosophical questions, including questions about the nature of philosophy and philosophical methodology itself.

In this essay I explore the resources Thomas Aquinas provides for enquiries concerning the psychological abilities of nonhuman animals. I first look to Aquinas’s account of divine, angelic, human, and nonhuman animal naming, to help us articulate the contours of a ‘critical anthropocentrism’ that aims to steer clear of the mistakes of a na¨ıve anthropocentrism and misconceived avowals to entirely eschew anthropocentrism. I then address the need for our critical anthropocentrism both to reject the mental-physical dichotomy endorsed by ‘folk psychology’ (...) and to articulate a more adequate ‘commonsense psychology’ that acknowledges most embodied animal behavior is observable psychological behavior. Next, I argue that we can develop Aquinas’s doctrine of estimation and conation to formulate an account of nonhuman animal action that more adequately characterizes the purposeful behaviors of nonhuman animals. To do so, we first need to recognize a wider range of nonhuman animal behaviors that are captured by Aquinas’s ‘estimative sense’, and that all of these behaviors are specified by a finite variety of particular goods confined to the animals’ environmental niches. But we also need to supplement Aquinas’s account of human and nonhuman animal agency by exploring the ontogeny and ecology of how humans and other animals become attuned to affordances within these different environmental niches. I argue that we should look to Aquinas’s account of nonhuman animal capacities in ST I-II 6-17 for subtle insights that can expand our understanding of how nonhuman animals engage in purposeful behavior by exercising analogous nonrational and imperfectly voluntary forms of intention, deliberation, choice, execution, and enjoyment. I conclude with an outline for how future enquiry can seek to explain the nonrational purposeful problem-solving competencies of chimps, canines, corvids, cetaceans, cephalopods, and other nonhuman animal species.

La actual crisis sanitaria nos invita a repensar el actual modelo de salud, así como sus implicaciones antropológicas, sociales y económicas. A partir de una breve historia del concepto de salud, en este artı́culo tratamos de evidenciar los cambios que ese mismo concepto ha implicado a nivel de relación médico-paciente y a nivel de relaciones sociales. Un nuevo paradigma de salud, más ajustado a los nuevos fenómenos globales que están aconteciendo, implica también una critica a los enfoques individualistas, reduccionistas, tecnocráticos (...) y economicistas que se encontraban en la raı́z del “antiguo” modelo de salud. Por último, proponemos el modelo One Health como una posible respuesta a los problemas teóricos del “antiguo paradigma” de salud, fuertemente enfatizados por la crisis sanitaria actual. (shrink)

This article, the second of a two-part essay, outlines a solution to certain tensions in Thomist philosophical anthropology concerning the interaction of the human person’s immaterial intellectual or noetic operations with the psychosomatic sensory operations that are constituted from the formal organization of the nervous system. Continuing with where the first part left off, I argue that Thomists should not be tempted by strong emergentist accounts of mental operations that act directly on the brain, but should maintain, with Aquinas, that (...) noetic operations directly interact with psychosomatic operations. I develop a Thomist account of noetic–psychosomatic interactions that expands upon the first part’s rapprochement between the new mechanist philosophy of neuroscience and psychology and hylomorphic animalism. I argue that noetic–psychosomatic interactions are best understood as analogous to the way diverse higher and lower order psychosomatic powers interact by actualizing, coordinating, and directing the operations of other psychosomatic powers. I draw on James Ross’s arguments for the immateriality of intellectual operations as realizing definite pure functions in order to elucidate the way noetic operations uniquely actualize, coordinate, and direct the psychosomatic operations they interact with. I conclude with a conjectural sketch of how this presentation of Thomist philosophical anthropology understands the noetic and psychosomatic deficits brought about by damage to the nervous system.

Thomas Aquinas consistently defended the thesis that the separated rational soul that results from a human person’s death is not a person. Nevertheless, what has emerged in recent decades is a sophisticated disputed question between “survivalists” and “corruptionists” concerning the personhood of the separated soul that has left us with intractable disagreements wherein neither side seems able to convince the other. In our contribution to this disputed question, we present a digest of an unconsidered middle way: the separated soul is (...) an incomplete person. (shrink)

In this paper, we explore the conceptual problems arising when using network analysis in person- centered care (PCC) in psychiatry. Personalized network models are potentially helpful tools for PCC, but we argue that using them in psychiatric practice raises boundary problems, i.e., problems in demarcating what should and should not be included in the model, which may limit their ability to provide clinically-relevant knowledge. Models can have explanatory and representational boundaries, among others. We argue that we can make more explicit (...) what kind of questions personalized network models can address in PCC, given their representational and explanatory boundaries, using perspectival reasoning.

I am tasked with addressing philosophical hazards in the neuroscientific study of religion. As a philosopher concerned with the well-being of neuroscientists studying religion, I am inclined to begin with the philosophical hazards of philosophy. I am well aware of the extraordinary difficulties of both tasks, for the hazards are many and it is easy to miss the forest for the trees or the trees for the forest. Instead of focusing on one issue in great detail, I shall hang a (...) number of warning signs around a forest of issues that identify various philosophical hazards which deserve particular caution when it comes to neuroscience and religion. Since I am aiming for breadth over depth, my brief remarks on each issue shall be synoptic, non-exhaustive, contentious and suggestive for additional consideration and reflection. To redress such deficits, I have provided references for further reading. (shrink)

This book discusses Aristotle’s notions of essence and substance as they are developed in Metaphysics ZH. I examine Aristotle's argument at length and defends an unorthodox interpretation according to which his motivation is to provide an answer against a conflation between criteria for existential priority (delivering substances as primary beings) and criteria for explanatory priority (delivering essences as primary principles).

This paper will argue that the order and the unity of St. Thomas Aquinas’s five ways can be elucidated through a consideration of St. Thomas’s appropriation of an Avicennian insight that he used to order and unify the wisdom of the Aristotelian and Abrahamic philosophical traditions towards the existence of God. I will begin with a central aporia from Aristotle’s Metaphysics. Aristotle says that the science of first philosophy has three different theoretical vectors: ontology, aitiology, and theology. But how can (...) all three be united into a single Aristotelian science? In his Metaphysics of the Healing, Avicenna resolved the impasse by taking the ontological vector as the subject of metaphysics. He then integrated the question of the four first causes into the penultimate stage of his demonstration for the existence of God, thereby placing aitiological and theological questions among the ultimate concerns of a unified Aristotelian metaphysics. In the five ways, St. Thomas integrated Avicenna’s Aristotelian search for the first four causes into the last four of his five ways, by showing that each of the four aitiological orders terminate in an ultimate first cause that we call God. Finally, by appending the proof from the Physics to the beginning of the five ways, St. Thomas was able to show that the ultimate aim of both natural philosophy and metaphysics is the divine first principle, which is the beginning and subject of sacra doctrina.

Is it necessary for all Christians – including Christians who are metaphysicians with demonstrative knowledge of God’s existence – to hold by faith that God exists? I shall approach this apparently straightforward question by investigating two opposing lines of interpretation of Thomas Aquinas’s own response to this question. I shall begin with two texts from Thomas that motivate two incompatible theses concerning Thomas’s doctrine of the harmony of faith and reason with respect to the existence of God. Next, I shall (...) clarify the salient points of disagreement between these two interpretations of faith and reason in Thomas Aquinas before examining dialectically a number of arguments in favor and against the respective theses of these two interpretations. In the final section I shall argue that the results of our dialectical inquiry reveal that the initial disagreement between the two positions is not irresolvable. Accordingly, I shall conclude by proposing two revised versions of the initial theses that emphasize the compatibility of these two interpretations of Thomas Aquinas’s doctrine of the harmony of faith and reason.

Although this article cannot cover the (...) phenomenon as a whole, we hope to outline a path for further investigation. (shrink)

Tradução preliminar em pré-print. A Tradução definitiva é a de 2009.

I have two aims in this paper. First, I argue that, in Aristotle’s theory of the four causes, there is a basic and common feature by which all causes are causes: they all work in a triadic framework in which they explain why a given attribute holds of a given underlying thing. Secondly, I argue against a version of “compatibilism” according to which each kind of cause is complete in its own domain and does not compete with any other kind. (...) I claim that there are priority relations according to which some kinds of cause are subordinated to others, even if these relations do not hold in every cases. (shrink)

This paper attempts to clarify the nature and the importance of a third kind of sophistic argument that is not always found in the classification of those arguments in the secondary literature. An argument of the third kind not only is a valid one, but is also constituted of true propositions. What makes it a sophistic argument is the fact that it produces a false semblance of scientific explanation: its explanation seems to be appropriate to the explanandum without being so. (...) Evidence from this kind of argument comes from Sophistic Refutations 11, and Brison’s attempt to square the circle should be counted as one of its instances. (shrink)

This paper discusses some issues concerning the definition of moral virtue in Nicomachean Ethics 1106b 36- 1107a 2. It is reasonable to expect from a definition the complete enumeration of the relevant features of its definiendum, but the definition of moral virtue seems to fail in doing this task. One might be tempted to infer that this definition is intended by Aristotle as a mere preliminary account that should be replaced by a more precise one. The context of the argument (...) Aristotle develops in Book II of his NE give us some help. I argue that the definition of moral virtue, once considered in the light of its context, is far from being an incomplete and provisional account: it rather introduces coherently the same notion of moral virtue that Aristotle employs in other texts (as in Nicomachean Ethics VI 13). My main proposal is that the way in which "hexis" is understood in the context of previous chapters allows Aristotle to encode in it the notion of an ability to do the right things regularly. Thus, moral virtue is a "hexis prohairetike etc.", but the ability to do the right things regularly is already encoded in the occurrence of "hexis" in the definiens account of moral virtue, as if Aristotle meant "hexis [praktike] prohairetike".

Commentary on Aristotle's Metaphysics Lambda. It accompanies the translation of Aristotle's Metaphysics Lambda into Portuguese in the same volume of the journal.

I examine Aristotle’s definition of scientific knowledge in Posterior Analytics 71b 9-12 and try to understand how it relates to the sophistical way of knowing and to "kata sumbebekos knowledge". I claim that scientific knowledge of p requires knowing p by its appropriate cause, and that this appropriate cause is a universal (katholou) in the restricted sense Aristotle proposes in 73b 26-27 ff., i.e., an attribute coextensive with the subject (an extensional feature) and predicated of the subject in itself (an (...) intensional feature). Kata sumbebekos knowledge, on the other hand, can occur even when the predicate of a conclusion is coextensive with its subject and is proved by a convertible meson which is not the most appropriate from an explanatory standpoint.

Translation of Aristotle's Physics I-II into Portuguese, with commentaries. Tradução para o português dos livros I e II da Física de Aristóteles, com comentários.

This paper explores some aspects of Aristotle’s notion of subject for predications. I examine the argument Aristotle develops in Posterior Analytics I.22, 83a1-14. I argue that the notion advanced by Aristotle in that argument is different from the one found in his Categories, although they are far from being incompatible with each other. I also add some philological considerations to justify the Portuguese translation of “hypokeimenon” as “algo subjacente” (“underlying thing”) instead of “sujeito” (“subject”).

My aim is to examine Aristotle's hylomorphism as a model for scientific explanation of living beings. I argue that the issue of matter-form relation should be connected with the opposition between the necessity of material and efficient causes and the teleology of forms. Form (as "telos") is a principle able to organize the appropriate conjunction of material and efficient causes. Formal and final causes are not a trick for filling the "gap in causation", nor are they bare heuristic tools for (...) inquiring into the "true" causes. The primacy of formal and final causes guarantees an appropriate account of material and efficient causes inasmuch as form and "telos" are responsible for bending and organizing the original dispositions of the material elements.

I discuss some of Aristotle’s scattered remarks from which one can construct his conception of matter. Aristotle seems to oscillate between two conceptions: one in which matter is the principle of becoming, another in which matter is a constituent element with no contribution for processes of becoming. Sometimes Aristotle takes matter as a thing independent in itself, and the correlated form is a feature that does not contribute to the matter’s essence, nor is a necessary condition for its existence. But (...) sometimes Aristotle takes matter as a constituent element the existence of which depends on the whole thing it is the matter of. These different approaches to matter seem to suggest an inconsistent theory of matter. However, I argue that, quite to the contrary, Aristotle has a consistent theory about matter. One of my main points is to distinguish contexts in which Aristotle is indeed talking about matter in general from contexts in which he uses the term “matter” to refer to a given thing that was previously taken as matter and to talk about that thing not qua matter, but qua the thing it is.

In Franz Rosenzweig's "The Star of Redemption" the chorus comes on stage in three forms: chorus in tragedy (with its presence in ancient classical tragedy and its absence in modern one), chorus of redemption and chorus in church music. Analyzing the role of chorus is useful to study Rosenzweig's aesthetics, which is in a way a "classical" art theory, but not an idealistic "pure" aesthetics, inasmuch as art must be "applied" art. An idealistic pure art condemns us to live in (...) an hortus conclusus, far away from God and from life, while an applied art brings us near to the lost gan 'eden. (shrink)

I discuss in this paper Aristotle’s definition of nature in Physics 192b 20-23. I intend to prove that this definition has to be taken as a set of three (not only two) conditions: the first condition just establishes that nature is a sort of cause; the second condition concerns the relationship between nature and the natural thing that has it as a cause; the third condition concerns the relationship between nature and the properties that natural things have from nature’s causality.

I discuss three kinds of relationship between ends and means (or "things that promote ends") in the Aristotelian ethical theory, in order to clarify how moral virtues and phronesis are related both in adopting ends and in determining means for virtuous actions. Phronesis seems to be mainly charged with determining means for an end given by the moral virtues, but it must involve some conception of ends too. Phronesis cannot be parasitic on moral virtue concerning the conception of ends, for (...) otherwise it will lack intrinsic moral value. I argue that the intrinsic moral value of phronesis can be better understood through a certain kind of relation between means and ends that has not received much attention. (shrink)

A filosofia da natureza de Aristóteles muitas vezes é apresentada como um capítulo inteiramente ultrapassado na história do pensamento: um “finalismo antiquado”, antropocêntrico, avesso à mensuração exata das condições materiais subjacentes aos fenômenos. Essa perspectiva, no entanto, é inadequada: não atenta para o papel relevante que Aristóteles atribui à matéria na explicação dos fenômenos naturais, assim como não atina com o real significado da teleologia aristotélica. Na contra-mão dessa perspectiva apressada, procuramos mostrar que, no cerne da filosofia aristotélica da natureza, (...) entendida como uma teleologia, encontra-se a idéia de que os seres naturais definem-se por uma tendência intrínseca à auto-preservação. É por essa tendência que a forma de cada ser natural governa teleologicamente sua matéria. (shrink)

Translation of Aristotle's Metaphysics V.1-8 with a few notes.

This paper is my first effort to revaluate the disagreement between two central texts for Aristotle's the conception of ousia: Categories and Metaphysics VII. Scholars have taken chapter Zeta-3 as a payment of the debt with the Categories, so that the hylomorphic analysis of the composite substance would require a revision of the subject-criterion, now improved by the addition of the “a this” and “separate” criterion. This paper, however, downgrades the importance of the Categories for understanding Aristotle's Metaphysics Z. The (...) two texts are dealing with different arguments and are not incompatible with one another. I myself consider this paper somehow obsolete, for I have returned to the same subject more than once: in my 2003 paper on Z-3 and, most importantly, on my Book 'As Noções Aristotélicas de Substância e Essência' (2008).

Eu examino cada meandro do esforço de Aristóteles identificar vários usos de termos filosóficos essenciais em sua Metafísica, V.9-17.

Frank Jackson’s knowledge argument (KA) aims to prove, by means of a thought experiment concerning the hypothetical scientist Mary, that conscious experiences have non-physical properties, called qualia. Mary has complete scientific knowledge of colours and colour vision without having had any colour experience. The central intuition in the KA is that, by seeing colours, Mary will learn what it is like to have colour experiences. Therefore, her scientific knowledge is incomplete, and conscious experiences have qualia. In this paper I consider (...) an objection to the KA raised by Daniel Dennett. He maintains that the KA is vitiated by Jackson’s account of Mary’s scientific knowledge. While endorsing this criticism, I will defend the plausibility and relevance of the type of strategy involved in the KA by offering an account of Mary’s scientific knowledge. This account involves formulating a reasonable and not immediately false version of the physicalist thesis with regard to colour experiences. Whether this version of the KA is successful against this type of physicalism is not investigated here. (shrink)

This PhD thesis is a careful discussion of Aristotle's Metaphysics VII (Zeta) almost line by line (or at least argument by argument). It might be interesting to know that a revised and shortened version of it was published as a book in Portuguese, "As Noções Aristotélicas de Substância e Essência", Campinas: Editora da Unicamp, 2008. Actually, I believe the original version of the PhD thesis has been superseded by the book.
