The author attempts to go beyond the study of the history of Islamic philosophy to the larger theme of religious dialogue between Christians and Muslims. He explores first some of the conditions that are required for any successful Christian-Muslim conversation. Next, he turns to some of the central issues specific to dialogue between Christians and Muslims. In addressing these themes he points to resources that are particularly useful to those trying to teach introductory courses on this complex matter, and to (...) give students an inkling of where they might look for further training to embark upon more advanced types of dialogue. In conclusion, the author returns to his starting point and considers various levels at which dialogue can be begun, even at an elementary stage. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:DOES GOD HAVE A QUIDDITY ACCORDING TO AVICENNA* IN THE NEW critical edition of Avicenna's MemphyS'ics by S. Van Riet at Louvain (I, 1977; II, 1980; III, 1983), Gerard Verbeke states that according to Avicenna, "L'Etre necessaire n'a pas une essence qui est distincte de son existence" (II, p. * 42, at note 159), i.e. that the Necessary Being does not have an essence that is distinct from its (...) existence. One looks in vain for a precise reference to an Avicennian text. On the other hand, in a three-part study, Albert G. Judy, O.P., "Avicenna's Me1taphy8'ics in the Summa contra Gentiles," published in Angelicum, part I: 52 (1975) 340-384; part II: 541-586; part Ill: 53 (1976) 183-226, states quite clearly that the "First" does not have a quiddity but only an "anity" (anitas)... (546), and that Avicenna... finds that the absolutely necessary being cannot have what every other reality has, namely, a quiddity, a "whatness " distinct from its" whether-ness" or anitas (547-548). Moreover, the first appendix of Judy's article contains a redaction of the 1495 and the 1508 Venice editions of ltletaphyiscs 8.4, which differs chiefly in punctuation from the excellent Van Riet text based on five Latin MSS. A slightly more nuanced position is. found in Etienne Gilson's Elements of Christian Philosoph;y (Garden City, N. Y.: Doubleday, 1960), p. 127: "... such exactly had been the con- * Delivered before the Society for the Study of Islamic Philosophy and Science meeting in conjunction with The American Catholic Philosophical Association in Milwaukee, Wisconsin, on April 12, 1985. 79 80 E. M. MACIEROWSKI clusion of Avicenna: the first has no quiddity (quidditatem non habet)," a claim that cites (305, note 28) secondary literature which one can trace as far back as Father M.-D. RolandGosselin 's edition of the De ente et essentia. What is at stake in this dispute? What if God does not have a quiddity? It would seem that He should be utterly unknowable, if quiddity or essence is a principle of knowledge as well as of being. Such would be plausible consequences of Gilson's and Judy's position. What, on the other hand, if God does have a quiddity? One possible inference, if we happened to have access or insight into the divine quiddity, is that we could have a sort of mystical union with God, perhaps even in this life; or again, one might draw pantheistic conclusions. Verbeke does not follow such paths. His inference points toward a rawrochement between Avicenna's doctrine and that of St. Thomas Aquinas, who maintained not only that God is His own essence (and therefore that it is reasonable to speak of a divine essence) but also that God's essence is no other than His esse, His being or existence. Accordingly, for scholars to have such opposed views about so important a topic even at the hermeneutical level of Avicenna's position points to a serious difficulty. Since Judy does offer texts in support of his interpretation, let us consider the evidence, using his section numbers and Van Riet's pages and lines: Judy, section 4=Van Riet 398.83-399.84 goes thus in Latin: Redibo igitur et dicam quod primum non habet quidditatem, nisi anitatem, quae sit discreta ab ipsa. This text he renders, "The first does not have a quiddity, except an 'anity,' which is distinct from it" (549). The other text in Latin (Judy, section 13=Van Riet 401.31-32) goes thus: Igitur necesse esse non habet quidditatem nisi quod est necesse esse, et haec est anitas, which he renders, "Therefore necessary being does not have a quiddity, but only the fact of its necessary being, and this is DOES GOD HAVE A QUIDDITY ACCORDING TO AVICENNA 81 'anity'" (559). We wonder, however, why nisi should be translated "except" in section 4 and "hut only" in section 13. One would have expected a sed solum or a sed tantum to justify the rendering "but only." Accordingly, the translation should be corrected to read, " Therefore the necessary being has no quiddity except that it is necessary being, and this... (shrink)

The text is divided into four chapters: 1.0 Metaphysics, transcendental philosophy and analytic philosophy; 2.0 The senses of being ; 3.0 Being and existence ; and 4.0 Modalities. After a defense of contemporary analytic philosophy against the usual charge of its supposedly superficial character and its lack of philosophical significance, Llano offers a thoughtful reading of Wittgenstein against his ancient, medieval and Kantian scholastic background. Following Gilson's historical analysis, Llano diagnoses a "tendency to reflect upon concepts with the risk of (...) forgetting the real things whose natures these concepts represent.... While the scholasticism most directly bound to Aristotle kept the consideration of real, concrete being firmly in view, Duns Scotus--in a direction already pointed out by Avicenna--was completely occupied with the concept of pure being ; a concept which, by being abstract, was understood as univocal. This perspective led him to 'prescind' from the actual reality of things, i.e., from their real existence; because, although existence itself is a notion or ratio knowable in the object, it is nevertheless required as actually belonging to the object in so far as it is knowable: 'existentia non est per se ratio obiecti, ut scibile est'". Against this background, being is taken as intelligibility, involving a relationship to the understanding that logicizes the meaning of being itself so that "the formal-essential dimension takes unto itself the whole weight of reality" and "esse is reduced to a quasi-accidental mode of the essence", which comes to be thematized in its own right as "the real modality, until a linguistic analysis, which can accept only the logical modality, passing through the logico-transcendental mediation of the gnoseological modality". Being is accordingly progressively "reabsorbed into human thought and later into various anthropological dimensions ". Section 1.3, "Toward a realist semantics," starts from Frege's attack on psychologism in the Foundations of Arithmetic and leads to a reinstatement of Aristotelian semantics in section 1.4, "Word and concept." Chapter 2 deals with the standard topics: 2.1, Predication, identity, existence; 2.2, being in propositions and being in reality; 2.3, accidental being ; and 2.4, being as it pertains to truth. Chapter 3 on being and existence suggests the thought-provoking comparison: as natura is to suppositum in Aquinas, so is Begriff to Gegenstand in Frege. Chapter 4, on the modalities of being, gets to the heart of the metaphysical issue of what happens when one of the modalities of being is substituted for being as the foundation of metaphysics. In Section 4.1, on actuality and facticity, Llano deftly centers attention on Heidegger's Grundprobleme der Phänomenologie, where Heidegger maintains that the Thomistic notion of actus essendi is merely another instance of the forgetfulness of being. Llano rightly judges that Heidegger's understanding of an opposition between essence as one thing and existence as another is derived from a position of Giles of Rome and has nothing to do with the position of Aquinas himself. Llano cites Avicenna roughly five times as often as he does Giles of Rome; Heidegger, apparently relying on hearsay reports, mentions Avicenna only once in the Grundprobleme der Phänomenologie, without citing any text, and mentions Giles of Rome three times, citing only one text. Heidegger uses a late scholastic as his authority for discrediting Aquinas. Llano quotes some of the explicit Thomistic criticisms against Avicenna including one that Heidegger partially omits ; the passage Heidegger suppresses begins "Opinio Avicennae fuit...." Though rhetorically subtle, Llano's clearly and forcefully written book is loaded with philosophical insights, bridges conversational gaps between analysts and phenomenologists, and offers a glimpse at some of the most important medieval notions sedimented within contemporary philosophy.--E.

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 187 Later Medieval Philosophy (1150-1350): An Introduction. By JOHN MARENBON. London and New York: Routledge & Kegan Paul, 1987. Pp. xi, 230. $35.00. Later Medieval Philosophy (LMP), the sequel to John Marenbon's 1983 Early Medieval Philosophy 480-1150 (EMP), aims to be not a historical account of later medieval philosophy but an " introduction... intended... to help " the reader " begin his own study of the subject (...) " (p. 1). To this end "Part One examines the organization of studies in medieval universities, the forms of writing and techniques of thought, the presuppositions and aims of thirteenth- and fourteenthcntury scholars. Part Two examines in detail the way in which some important later medieval thinkers discussed a difficult and central question : the nature of intellectual knowledge" (p. 1). Marenbon justifies his two-fold approach in the "Conclusion to Part One: What is Medieval Philosophy? " (pp. 83-90). Surveying three current approaches to medieval philosophy, Marenbon notes (1) a ' separationism ' between philosophy and theology provoked by ' rationalists ' like V. Cousin and B. Haureau and preserved in Catholic philosophical circles by such exponents as Fernand von Steenberghen; (2) a view that agrees " that it is right to consider the history of medieval philosophy as a separate subject from the history of medieval theology; but it is a philosophy which, nonetheless, depends on Christian revelation and cannot be understood in abstraction from certain funda· mental tenets of the faith," viz. that of Etienne Gilson who maintains the existence of a 'Christian philosophy'; and (3) the 'modern analytic approach' advocated by Norman Kretzmann and others in the Cambridge History of Later Medieval Philosophy ("to end the era in which it has been studied in a philosophical ghetto"). The third ap· proach de-emphasizes " the theological context " of " the particular philosophical arguments they isolate " and " the origin and literary form of texts " (p. 87) to " concentrate on the philosophical problems which they believe they share with medieval scholars " and " to translate medieval texts so far as possible into modern terms..." (pp. 8687 ). The arguments for these three approaches, however, are "based, not on historical evidence about medieval attitudes to philosophy, hut on different conceptions of what philosophy should he" (p. 88). These hermeneutical presuppositions affect the selection and arrangement of evidence by the various sorts of historian. Marenhon offers a fourth approach: ' historical analysis ', which " aims both to bridge the distance between the interests and assumptions of a modern reader and 188 BOOK REVIEWS the writings of later medieval thinkers, and yet to take account of it " (p. 89). Two restrictions are involved; historical analysts must not make " anachronistic assumptions about the identity of the problems discussed in their texts" (p. 89) and must restrict the scope of their investigations " to a single topic (or a set of individual topics) " rather than" writing... comprehensive Histories" (p. 90). Marenhon seems to recognize that there may he " patronizing " ways to take account of the difference between " medieval scholars " and " ourselves " hut such " limitations " are inescapable " conditions of disciplined thought " (p. 191). Fortunately Marenhon has moved away from the parochial assumption governing his Early Medieval Philosophy "that any thinker who appeared to share the methods and interests of ·modern British philosophers was a philosopher, and that all other thinkers were theologians, mystics, poets, scientists or whatever, hut not philosophers." He now holds "that there is no single, identifiable subject-' philosophy'which has been studied from Plato's time to the present day" (EMP, 1988 rev. ed., p. vii). Thus, Marenhon does not explicitly entertain the grand thesis that all or the most important forms of medieval philosophy are actually superior to all or the most important kinds of modern philosophy to justify the importance of studying medieval philosophy today (cf. Leo Strauss, Philosophie und Gesetz). Instead Marenhon, noting that " philosophia has a wide range of reference " (LMP, p. 66) and tacitly assuming that philosophy is an important activity, focuses on the problem of intellectual knowledge. The selection of exactly this problem, however, is not incompatible with the view that the epistemological turn characteristic of modern philosophy is still taken as normative. Accordingly, Marenhon provokes in us such questions as, Is philosophy today as good as philosophy in the hands... (shrink)

Prominent models of attentional control assert a dichotomy between top-down and bottom-up control, with the former determined by current selection goals and the latter determined by physical salience. This theoretical dichotomy, however, fails to explain a growing number of cases in which neither current goals nor physical salience can account for strong selection biases. For example, equally salient stimuli associated with reward can capture attention, even when this contradicts current selection goals. Thus, although 'top-down' sources of bias are sometimes defined (...) as those that are not due to physical salience, this conception conflates distinct - and sometimes contradictory - sources of selection bias. We describe an alternative framework, in which past selection history is integrated with current goals and physical salience to shape an integrated priority map. (shrink)

Since its first publication in 1961 E.H. Carr's What is History? has established itself as the classic introduction to the subject. Ranging across topics such as historical objectivity, society and the individual, the nature of causation, and the possibility of progress, Carr delivered an incisive text that still has power to provoke debate today. For this fortieth anniversary reissue, Richard J. Evans has written an extensive new introduction that discusses the origins and the impact of the book, and assesses its (...) relevance in the age of the 21st century postmodernism and epistemological anxiety.

In this paper, the author derives the Dedekind-Peano axioms for number theory from a consistent and general metaphysical theory of abstract objects. The derivation makes no appeal to primitive mathematical notions, implicit definitions, or a principle of infinity. The theorems proved constitute an important subset of the numbered propositions found in Frege's *Grundgesetze*. The proofs of the theorems reconstruct Frege's derivations, with the exception of the claim that every number has a successor, which is derived from a modal axiom that (...) (philosophical) logicians implicitly accept. In the final section of the paper, there is a brief philosophical discussion of how the present theory relates to the work of other philosophers attempting to reconstruct Frege's conception of numbers and logical objects.

Standard models of concept learning generally focus on deriving statistical properties of a category based on data (i.e., category members and the features that describe them) but fail to give appropriate weight to the contact between people's intuitive theories and these data. Two experiments explored the role of people's prior knowledge or intuitive theories on category learning by manipulating the labels associated with the category. Learning differed dramatically when categories of children's drawings were meaningfully labeled (e.g., “done by creative children”) (...) compared to when they were labeled in a neutral manner. When categories are meaningfully labeled, people bring intuitive theories to the learning context. Learning then involves a process in which people search for evidence in the data that supports abstract features or hypotheses that have been activated by the intuitive theories. In contrast, when categories are labeled in a neutral manner, people search for simple features that distinguish one category from another. Importantly, the final study suggests that learning involves an interaction of people's intuitive theories with data, in which theories and data mutually influence each other. The results strongly suggest that straight‐forward, relatively modular ways of incorporating prior knowledge into models of category learning are inadequate. More telling, the results suggest that standard models may have fundamental limitations. We outline a speculative model of learning in which the interaction of theory and data is tightly coupled. The article concludes by comparing the results to recent artificial intelligence systems that use prior knowledge during learning. (shrink)

In sentences like Every teacher laughed we think of every teacher as a unary (=type (1)) quantifier - it expresses a property of one place predicate denotations. In variable binding terms, unary quantifiers bind one variable. Two applications of unary quantifiers, as in the interpretation of No student likes every teacher, determine a binary (= type (2)) quantifier; they express properties of two place predicate denotations. In variable binding terms they bind two variables. We call a binary quantifier Fregean (or (...) reducible) if it can in principle be expressed by the iterated application of unary quantifiers. In this paper we present two mathematical properties which distinguish non-Fregean quantifiers from Fregean ones. Our results extend those of van Benthem (1989) and Keenan (1987a). We use them to show that English presents a large variety of non-Fregean quantifi ers. Some are new here, others are familiar (though the proofs that they are non-Fregean are not). The main point of our empirical work is to inform us regarding the types of quantification natural language presents - in particular (van Benthem, 1989) that it goes beyond the usual (Fregean) analysis which treats it as mere iterated application of unary quantifiers. Secondarily, our results challenge linguistic approaches to "Logical Form" which constrain variable binding operators to "locally" bind just one occurrence of a variable, e.g., the Bijection Principle (BP) of Koopman and Sportiche (1983). The BP (correctly) blocks analyses like For which x, x's mother kissed x? for Who did his mother kiss? since For which x would locally bind two occurrences of x. But some of our irreducible binary quantifiers are naturally represented by operators which do locally bind two variables. This paper is organized as follows: Section 1 provides an explicit formulation of our questions of concern. Section 2 classifies the English constructions which we show to be non-Fregean. Section 3 presents the mathematical properties which test for non-Fregean quantification and applies these tests to the constructions in Section 2. Proofs of the mathema tical properties are given in the Appendix. (shrink)

We present the first large-scale, quantitative examination of mind and body concepts in a set of historical sources by measuring the predictions of folk mind–body dualism against the surviving textual corpus of pre-Qin (pre-221 BCE) China. Our textual analysis found clear patterns in the historically evolving reference of the word xin (heart/heart–mind): It alone of the organs was regularly contrasted with the physical body, and during the Warring States period it became less associated with emotions and increasingly portrayed as the (...) unique locus of “higher” cognitive abilities. We interpret this as a semantic shift toward a shared cognitive bias in response to a vast and rapid expansion of literacy. Our study helps test the proposed universality of folk dualism, adds a new quantitative approach to the methods used in the humanities, and opens up a new and valuable data source for cognitive scientists: the record of dead minds.

We address how listeners perceive temporal regularity in music performances, which are rich in temporal irregularities. A computational model is described in which a small system of internal self‐sustained oscillations, operating at different periods with specific phase and period relations, entrains to the rhythms of music performances. Based on temporal expectancies embodied by the oscillations, the model predicts the categorization of temporally changing event intervals into discrete metrical categories, as well as the perceptual salience of deviations from these categories. The (...) model's predictions are tested in two experiments using piano performances of the same music with different phrase structure interpretations (Experiment 1) or different melodic interpretations (Experiment 2). The model successfully tracked temporal regularity amidst the temporal fluctuations found in the performances. The model's sensitivity to performed deviations from its temporal expectations compared favorably with the performers' structural (phrasal and melodic) intentions. Furthermore, the model tracked normal performances (with increased temporal variability) better than performances in which temporal fluctuations associated with individual voices were removed (with decreased variability). The small, systematic temporal irregularities characteristic of human performances (chord asynchronies) improved tracking, but randomly generated temporal irregularities did not. These findings suggest that perception of temporal regularity in complex musical sequences is based on temporal expectancies that adapt in response to temporally fluctuating input. (shrink)

Western scholarship on early Chinese thought has tended to either dismiss the foundational role of metaphor or to see it as a uniquely Chinese mode of apprehending the world. This article argues that, while human cognition is in fact profoundly dependent on imagistic conceptual structures, such dependence is by no means a unique feature of Chinese thought. The article reviews empirical evidence supporting the claims that human thought is fundamentally imagistic; that sensorimotor schemas are often used to structure our understanding (...) of abstract concepts; that these schemas can be selectively combined to result in novel structures; and that there are inextricable connections between body, emotion, and thought in both everyday and philosophical cognition. It also provides a review of a recent trend where, explicitly or not, scholars from a variety of backgrounds have begun to take metaphor more seriously as a foundational bearer of philosophical meaning in early China.

The purpose here is to explore metaphorical conceptions of the self in a fourth century B.C.E. Chinese text, the Zhuangzi, from the perspective of cognitive linguistics and the contemporary theory of metaphor. It is argued that the contemporary theory of metaphor provides scholars with an exciting new theoretical grounding for the study of comparative thought, as well as a concrete methodology for undertaking the comparative project. What is seen when the Zhuangzi is examined from the perspective of metaphor theory is (...) that conceptions of the self portrayed in this text are based on a relatively small set of interrelated conceptual metaphors, and that the metaphysics built into the Zhuangzi's classical Chinese metaphors resonates strongly with the (mostly unconscious) metaphysical assumptions built into the metaphors of modern American English. This should not be surprising, considering the claims of contemporary cognitive linguists that the metaphoric schemas making up the foundation of human abstract conceptual life are not arbitrarily created ex nihilo, but rather emerge from common embodied experience and are conceptual, rather than merely linguistic, in nature.

This paper tries to capture Salvador Dali’s conception of a genius in his Diary of a Genius. The Japanese writer Mishima strikes me as of a comparable level, but if so it seems he either does not think of himself as a genius or he has a different conception of genius.

I present a sense of the term “ideal theory” based on Joseph Raz’s response to the situation of a lifeguard faced with three drowning on one side and two on the other and unable to save all. From what is of value, such a theory builds up a conception of an ideal political state or an aspect of it which we have reason to realize, but ignoring whether it is possible for us to realize this.

The term, “bioethics” was coined in 1970 by American cancerologist V. R. Potter. In the few decades since, the field of bioethics has emerged as an important discipline. The field has attained a remarkable degree of public recognition in a relatively short period of time. The “right to die” cases such as In re Quinlan placed bioethical issues on the front pages. Although the discipline is of recent vintage, the past quarter century has witnessed a flurry of scholarly activity, creating (...) a substantial body of bioethical literature. Moreover, the bioethics movement has manifested itself in institutional expressions. Universities and medical schools have added courses in bioethics to their curricula. In 1974, federal legislation and regulations mandated that federal grantees conducting human subjects research establish institutional review boards to safeguard subjects’ welfare, and even absent a legislative mandate numerous hospitals created ethics committees. Centers and institutes, devoted exclusively to the study of bioethical issues, have been founded. (shrink)

Apparently the Western philosophical tradition has (wrongly) preferred speech over writing – so claims Jacques Derrida. In this paper, I consider whether utilitarianism involves such a preference. There are at least two arguments against the claim.

In this paper, I present a problem for regarding the reflective equilibrium and original position methods as consistent. I do not prove that there is an inconsistency, but there is a puzzle of how the two methods can be made consistent. The concern about inconsistency is because the former method allows for a kind of historical bias, as noted by T.H. Irwin, whereas the latter method seeks to guard against historical bias.

What are the implications of taking seriously Chaïm Perelman's proposition that “definitions are rhetorical”? Efforts to find Real Definitions are dysfunctional to the extent they direct argumentation toward pseudo “is” claims and away from explicit “ought” claims about how words are to be used. Addressing definitional disputes explicitly as propositions ofought rather thanis could put on the agenda the pragmatic concerns of definitional choice that might otherwise remain tacit.

Engaged scholarship is an intellectual movement sweeping across higher education, not only in the social and behavioral sciences but also in fields of natural science and engineering. It is predicated on the idea that major advances in knowledge will transpire when scholars, while pursuing their research interests, also consider addressing the core problems confronting society. For a workable engaged agenda in science and technology studies, one that informs scholarship as well as shapes practice and policy, the traditional terms of engagement (...) must be renegotiated to be more open and mutual than has historically characterized the nature of inquiry in this field. At the same time, it is essential to protect individual privacy and preserve government confidentiality. Yet there is a scientific possibility for and benefit to introducing more collaborative and deliberative research approaches between scholar and subject in ways that will not violate these first-order ethics. To make the case, this article discusses the possibilities and perils of engaged science and technology scholarship by drawing on our own recent experiences to conduct and apply STS research while embedded in the National Science Foundation. Brief accounts of these experiences reveal the opportunities as well as the challenges of engaged scholarship. They also provide lessons for those fellow travelers who might follow the authors to this or other like host organizations with ambitions of increasing fundamental knowledge about and applying research to the policies, programs, and decisions of the scientific enterprise.
