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...

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.

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.
