Analytical expressions for the matrices and an explicit algorithm for computing Clebsch-Gordan coupling coefficients are given forsu(4) in au(3)-coupled basis as an example of the construction for anysu(n) in au(n−1) basis. The results areinduced from the known results foru(3) by means of the vector-coherent-state (VCS) theory of induced representations. The important recent result that makes this possible is the discovery that a complete set of shift tensors for the finitedimensional representations of reductive Lie algebras can be induced, by VCS methods, (...) from those of suitably defined subalgebras.

There are ten studies in the collection, three (1-3) previously unpublished, six either in press or already published (4-8, 10) either in French or in English ; the ninth was published in Portuguese, but now appears in French. One of the latter seven items (no.8) has evidently been revised ; otherwise only 1-3 appear to be genuinely new. 4-10 also seem by and large to retain their original formatting ; there are no cross-references – none, at any rate, that I (...) have observed – between the piece...

This is the first full-length biography of John Langshaw Austin (1911–60). The opening four chapters outline his origins, childhood, schooling, and time as an undergraduate, while the next four examine his early career in professional philosophy, looking at the influence of Oxford Realism, Logical Positivism, Pragmatism, and the later Wittgenstein. The central twelve chapters then explore Austin’s wartime career in British Intelligence. The first three examine the contributions he made to the campaigns in North Africa; the next seven the seminal (...) role he played in ensuring the outstanding accuracy of the D-Day Intelligence; while the final two explore his contributions to Arnhem, the Ardennes, and the post-war administration of Germany. The last main section of the book then outlines and assesses Austin’s contributions to post-war Oxford Ordinary Language Philosophy. The first three chapters discuss the impact on Oxford philosophy of the cultural atmosphere of post-war Britain and the later Wittgenstein’s ideas. The next four look at Austin’s influence on post-war Oxford, particularly his Saturday morning discussion group and his perception lectures. The next five chapters concentrate on America’s influence on Austin and vice versa, paying particular attention to Austin’s work on speech-acts and his semesters in Harvard and Berkeley. The final two chapters examine Austin’s declining influence in Oxford, and his tragically premature death. (shrink)

From the title of this volume—which resists the temptation to call Parmenides, Heraclitus, and Anaximander "pre-Socratics"—to the high quality of the translations, this book is an extended exercise in faithfulness to the text of Martin Heidegger. This is in my judgment the most successful attempt yet in the Sisyphian task of translating Heidegger’s works into English which Harper & Row has been undertaking in the past fifteen years. The volume consists in three essays on Parmenides and Heraclitus which appear together (...) and in the same order in Heidegger’s Vorträge und Aufsätze ; these are preceded by the important essay on Anaximander which is taken from Holzwege. These essays in the original German are written in the full bloom of Heidegger’s attempt to liberate language from logic and to find, not only the vocabulary, but also the grammar which is required in order to bring the matter to be thought into language. They are therefore in any strict sense untranslatable. They exist only in German, in the language in which they have come to birth. But the Krell-Capuzzi translation is as faithful an attempt as one could hope for to bring this matter into English, and so to introduce those who are coming to grips with Heidegger for the first time to a very important dimension of his thought, and to help those of us who have been at this for some time to hear these German words anew. What more can one say about a translation than that it helps one to understand the original? And that is what this volume does. (shrink)

It is perhaps no accident that one of the finest books to appear on Heidegger in any language should come to us from the East. Mehta’s book was first published in India. The present Harper & Row edition constitutes chapters I, VIII, IX and X of that volume, the chapters devoted to Being and Time in the original having been omitted. That decision can only be regretted because, if the chapters on Being and Time are of the same quality as (...) those here published, they should be made available to us. What we have in fact then is a study of the later Heidegger, preceded by an introductory analysis of Heidegger’s method and language. Mehta’s scholarship is exhaustive, his numerous and lengthy notes touching upon all the major sources in the literature. His interpretation is so incisive that it is no exaggeration to place this book along with the works of Poeggeler and Marx among the outstanding studies of Heidegger’s thought. There is a great need for a thorough and reliable treatment of the later Heidegger in a readable English and Mehta’s book fills the bill.—J. D. C. (shrink)

A bivalent valuation is snt iff sound (standard PC inference rules take truths only into truths) and non-trivial (not all wffs are assigned the same truth value). Such a valuation is normal iff classically correct for each connective. Carnap knew that there were non-normal snt valuations of PC, and that the gap they revealed between syntax and semantics could be "jumped" as follows. Let $VAL_{snt}$ be the set of snt valuations, and $VAL_{nrm}$ be the set of normal ones. The bottom (...) row in the table for the wedge 'v' is not semantically determined by $VAL_{snt}$ , but if one deletes from $VAL_{snt}$ all those valuations that are not classically correct at the aforementioned row, one jumps straights to $VAL_{nrm}$ and thus to classical semantics. The conjecture we call semantic holism claims that the same thing happens for any semantic indeterminacy in any row in the table of any connective of PC, i.e., to remove it is to jump straight to classical semantics. We show (i) why semantic holism is plausible and (ii) why it is nevertheless false. And (iii) we pose a series of questions concerning the number of possible steps or jumps between the indeterminate semantics given by $VAL_{snt}$ and classical semantics given by $VAL_{nrm}$.

This chapter, ‘Friendship and the Moral Life in Iris Murdoch’s Novels’ revisits the subject of sexual relationships, not from the problematic perspective brought to them in Anne Rowe’s earlier chapter, but in a positive light. In his analysis of the educational potential of friendship and sexuality Robert Baker contends that sexual intimacy teaches Murdoch’s characters not only about themselves and their own identity but also about the reality of the other person. It thus acts as a force for learning (...) to attend to the world outside the self which is the desideratum of Murdoch’s moral pilgrimage. He surveys the apparent acceptance by Murdoch scholars that such moral development is necessarily a solitary and lonely endeavour before juxtaposing that impression—given prominence in the M and D scenario Murdoch creates in The Sovereignty of Good (1970)—with the relationships she portrays in her novels. Close readings of the friendship of Tom MacCaffrey and Emmanuel Scarlett-Taylor in The Philosopher’s Pupil (1983) and of Harvey Blackett’s relationship with Sefton Anderson in The Green Knight support Baker’s contention that physical affection can be a guide to the good. Borrowing an image from the latter novel he claims that in her fiction ‘Murdoch represents the moral life not as a lonely pilgrimage toward reality, but as a passeggiata with others in which one gives way to a movement larger than and beyond oneself’ (177), a viable interpretation which reads the passeggiata with an interestingly different slant from other current critics such as Rebecca Moden, who regards it as Murdoch’s ‘metaphor for the nature of human existence’ and ‘a troubling image of the impoverished quality of human consciousness in the late twentieth century’.

Under the careful editorship of R. A. Markus, this book appears to be one of the very finest anthologies of critical essays dedicated to the elucidation of the thought of St. Augustine. Those familiar with Markus’ contribution to The Cambridge History of Later Greek and Early Medieval Philosophy will readily attest to the depth as well as to the breadth of understanding which Markus brings to Augustine scholarship. Three of the essays appear for the first time: "Action and Contemplation," by (...) Robert J. O’Connell; "Si Fallor, Sum," by Gareth B. Matthews; "On Augustine’s Concept of a Person," by A. C. Boyd. The remaining articles have appeared either as separate pieces or as journal articles: "St. Augustine and Christian Platonism," by A. H. Armstrong; "St. Augustine on Signs," by R. A. Markus; "The Theory of Signs of St. Augustine’s De Doctrina Christiana," by B. Darrell Jackson; "Augustine on Speaking from Memory" and "The Inner Man," by Gareth B. Matthews; "Augustine on Foreknowledge and Free Will," by William L. Rowe; "Augustine on Free Will and Predestination," by John M.

Brown; "The Development of Augustine’s Ideas on Society before the Donatist Controversy" and "De Civitate Dei, XV, 2, and Augustine’s Idea of the Christian Society," The essays display scholarly depth as well as concern for contemporary philosophical problems. It is an excellent addition to Augustine scholarship and to contemporary philosophizing.

In lieu of an abstract, here is a brief excerpt of the content:MOLTMANN'S POST-MODERN MESSIANIC CHRISTOLOGY: A REVIEW DISCUSSION 1 PAUL D. MOLNAR St. Johns University Jamaica, New York 0 VER TWENTY-FIVE years ago Jiirgen Moltmann's response to Karl Barth's suggestion that it might be wise to " accept the doctrine of the immanent trinity of God " 2 indicated the future of his theology: " in studying C.D. at these points I always lost my breath. I suspect you are (...) right but I cannot as yet or so quickly enter into this right." Moltmann believed he could present the " economic Trinity " in such a way that " in the foreground, and then again in the background, it would be open to an immanent Trinity... the Holy Spirit is first the Spirit of the raising of the dead and then as such the third person of the Trinity." 3 Moltmann's The Way of Jesus Christ reflects the same onesidedness that Barth had criticized in his theology of hope, and this predicament leads to his own distinct messianic christology, as we shall see. This third volume in Moltmann's systematic theology, following his Trinity and the Kingdom and God in 1 The Way of Jesits Christ: Christology fo Messianic Dimensions. By Jiirgen Moltmann.

Barth's Church Dogmatics is usually abbreviated as C.D. 669 670 PAUL D. MOLNAR Creation,4 is intended to lead to a fourth volume on Redemption. Like Moltmann's other works it is tightly written, difficult, intriguing and informative. His writing is clear and his position certainly is developed with a commendable systematic rigor. Throughout this book, which contains seven chapters with clear headings indicating the topics to be treated, the reader is compelled to admire Moltmann's ability to weave together immense amounts of scriptural and systematic data without losing his own position in the process. While the wealth of information alone makes this book worth studying, there is much more than information here. Yet the problem with this book is apparent throughout, i.e., Moltmann attempts to reconceive christology not from a superior knowledge of the person and work of Jesus Christ as presented in scripture but from the community's experience of Jesus Christ in the present. Hence he begins his own " pneumatological christology " with the experience of discipleship (xiv) and argues against the traditional christologies, on the basis of " Christopraxis " which he says is "the source from which christology springs " (41). But can we say that our discipleship is the "source" of christology when, according to Matt. 16 :17, flesh and blood did not disclose who Jesus was-rather, this was revealed by God? This substitution of experience for a real action of the trinity within history is the weakness of Moltmann's bold attempt to revise christology.5 I hope to show how this problem affects Moltmann's method and conclusions. While I agree with Moltmann's intention to present a christology which makes sense in a post-modern environment, I hope to illustrate that by beginning with experience rather than with the Word of God revealed, 4 Jiirgen Moltmann, God in Creation: A New Theology of Creation and the Spirit of God (San Francisco: Harper and Row, 1985), pp. xv-365.

The concept of public participation is one of growing interest in the UK and elsewhere, with a commensurate growth in mechanisms to enable this. The merits of participation, however, are difficult to ascertain, as there are relatively few cases in which the effectiveness of participation exercises have been studied in a structured manner. This seems to stem largely from uncertainty in the research community as to how to conduct evaluations. In this article, one agenda for conducting evaluation research that might (...) lead to the systematic acquisition of knowledge is presented. This agenda identifies the importance of defining effectiveness and of operationalizing one’s definition. The article includes analysis of the nature of past evaluations, discussion of potential difficulties in the enactment of the proposed agenda, and discussion of some potential solutions. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Form and Argument in Late Plato ed. by Christopher Gill and Mary Margaret McCabeFrancisco J. GonzalezChristopher Gill and Mary Margaret McCabe, editors. Form and Argument in Late Plato. Oxford: Oxford University Press, 1996. Pp. xi + 345. Cloth, $65.00.This collection has the commendable aim of challenging the view that in Plato’s “late” works the dialogue form is a mere formality adding little to the argumentative content, a view (...) still widespread among “analytic” scholars. The qualification is necessary because this view has already been seriously challenged by “nonanalytic” interpreters. It is therefore surprising that the editors chose contributors who almost all “share the analytic’ approach which is prominent in Anglo-American scholarship on Plato,” despite their admission that this approach has focused more on arguments than on the dialogue form (2, 299–300). Why seek to reinvent the wheel without the help of those who have already invented it? As a result, while the volume certainly makes an important contribution to our understanding of the form of this group of dialogues, it is much more successful in providing helpful and illuminating readings of their argumentative content: the detailed and rigorous analyses of McCabe, Malcolm Schofield (both on the Parmenides), and Gail Fine (on the Theaetetus) deserve special mention. The aim of the present review, which could not even begin to do justice to what the volume provides in the latter area, is therefore limited to documenting its mixed success in addressing some fundamental questions about form that have already occupied nonanalytic scholars (perhaps too exclusively):1) Does the main speaker speak for Plato?Given the great variety of main speakers in the “late” dialogues (Socrates, Parmenides, the Eleatic Stranger, Timaeus, the Athenian Stranger), each with a distinct personality and a distinct method, no attempt to understand the form of these dialogues should avoid this question. Gill raises it (293–95) and Schofield provides the most explicit response in denying that any interlocutor in a Platonic dialogue “can be assumed to be merely a spokesman for Plato’s own views” (51). More importantly, the essays by Dorothea Frede (on the Philebus) and Catherine Osborne (on the Timaeus), probably the most valuable in the volume, show what results can be achieved without this assumption. On the other hand, Michael Frede (on the Sophist) and Christopher Rowe (on the Politicus; see 158 and cf. 172 n.48) simply assume without argument that the Eleatic Stranger = Plato. All other contributors make the “spokesman” assumption, either implicitly or explicitly (see Christopher Bobonich’s reading of the Laws, 254–55).2) What is the significance of the dramatic context, especially dramatic chronology and characterization?As often noted, the Parmenides is set in Socrates’ youth and is in this sense the earliest [End Page 311] dialogue, while the series Theaetetus-Sophist-Politicus is set immediately before Socrates’ trial and condemnation. McCabe and Schofield are silent about the first fact. M. Frede briefly discusses the second (146–47), but adds little to what has already been said by others. As for the characterization of specific interlocutors, this volume overall has surprisingly little to offer. The essays of D. Frede and Osborne, however, are exemplary in this area.3) Why did Plato choose to write these works as dialogues rather than as treatises?Bobonich, D. Frede, and Osborne succeed in demonstrating the significance and even necessity of the dialogue form, an extraordinary achievement given the dialogues they discuss. Osborne in particular brilliantly shows how the dialogue form undercuts the common tendency to read the Timaeus as a treatise on natural science. Other contributors are less successful in answering this question central to the volume’s task. Schofield takes himself to be reading the Parmenides as a dialogue (51) because he, unlike Vlastos, interprets the Third Man Argument (second version) in the wider context of other arguments in the dialogue, including those of the second half. But “reading arguments in context” is demanded by any philosophical text and has nothing per se to do with the dialogue form. Fine reads the first part of the Theaetetus as the dialectical elaboration and refutation of an opponent’s view (109), but this could just as well be... (shrink)

Imprecise definition of key terms in the “public participation” domain have hindered the conduct of good research and militated against the development and implementation of effective participation practices. In this article, we define key concepts in the domain: public communication, public consultation, and public participation. These concepts are differentiated according to the nature and flow of information between exercise sponsors and participants. According to such an information flow perspective, an exercise’s effectiveness may be ascertained by the efficiency with which full, (...) relevant information is elicited from all appropriate sources, transferred to all appropriate recipients, and combined to give an aggregate/consensual response. Key variables that may theoretically affect effectiveness—and on which engagement mechanisms differ—are identified and used to develop a typology of mechanisms. The resultant typology reveals four communication, six consultation, and four participation mechanism classes. Limitations to the typology are discussed, and future research needs identified.

There is a growing call for greater public involvement in establishing science and technology policy, in line with democratic ideals. A variety of public participation procedures exist that aim to consult and involve the public, ranging from the public hearing to the consensus conference. Unfortunately, a general lack of empirical consideration of the quality of these methods arises from confusion as to the appropriate benchmarks for evaluation. Given that the quality of the output of any participation exercise is difficult to (...) determine, the authors suggest the need to consider which aspects of the process are desirable and then to measure the presence or quality of these process aspects. To this end, a number of theoretical evaluation criteria that are essential for effective public participation are specified. These comprise two types: acceptance criteria, which concern features of a method that make it acceptable to the wider public, and process criteria, which concern features of the process that are liable to ensure that it takes place in an effective manner. Future research needs to develop instruments to measure these criteria more precisely and identify the contextual and environmental factors that will mediate the effectiveness of the different participation methods.

Multiple -conclusion logic extends formal logic by allowing arguments to have a set of conclusions instead of a single one, the truth lying somewhere among the conclusions if all the premises are true. The extension opens up interesting possibilities based on the symmetry between premises and conclusions, and can also be used to throw fresh light on the conventional logic and its limitations. This is a sustained study of the subject and is certain to stimulate further research. Part I reworks (...) the fundamental ideas of logic to take account of multiple conclusions, and investigates the connections between multiple - and single - conclusion calculi. Part II draws on graph theory to discuss the form and validity of arguments independently of particular logical systems. Part III contrasts the multiple - and the single - conclusion treatment of one and the same subject, using many-valued logic as the example; and Part IV shows how the methods of 'natural deduction' can be matched by direct proofs using multiple conclusions.
