Indole is a key environmental cue that is used by many organisms. Based on its biochemistry, we suggest indole is used so universally, and by such different organisms, because it derives from the metabolism of tryptophan, a resource essential for many species yet rare in nature. These properties make it a valuable, environmental cue for resources almost universally important for promoting fitness. We then describe how indole is used to coordinate actions within organisms, to influence the behavior of conspecifics and (...) can even be used to change the behavior of species that belong to other kingdoms. Drawing on the evolutionary framework that has been developed for understanding animal communication, we show how this is diversely achieved by indole acting as a cue, a manipulative signal, and an honest signal, as well as how indole can be used synergistically to amplify information conveyed by other molecules. Clarifying these distinct functions of indole identifies patterns that transcend different kingdoms of organisms. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 165 arguments. He meets them head on, on their ground; whether or not he is deemed successful, he presents a challenge not only to the philosophers he adduces but also to anyone in the Thomistic tradition who has judged confrontation with contemporary critics to he fruitless. JANICE L. SCHULTZ Canisius College Buffalo, New York Authority and Leadership in the Church: Past Directions and Future Possibilities. By (...) class='Hi'>THOMAS P. RAUSCH, S.J. Wilmington, Del.: Michael Glazier, 1989. Pp. 158. $15.95. Rather than offering a sustained study of the question of authority and leadership in the Church, Rausch presents a collection of essays related to the topic. The format reflects the book's genesis: much of the material was developed for the 23rd Faith and Order Conference of the Texas Conference of Churches on the subject "Authority in the Body of Christ." Although the title does not reflect the hook's ecumenical focus, readers who want a general introduction to the present status of agreement in ecumenical discussion of authority and ministry may find Rausch's hook helpful. In " Authority in the Ecumenical Dialogue " Rausch reviews and summarizes the ARCIC Final Report, the Lutheran-Roman Catholic Dialogue, the WCC Baptism, Eucharist and Ministry text, and the Consultation on Church Union. The emerging consensus on the value of ordained ministry in these documents indicates that this ministry is permanent, although the threefold ministry of bishop, presbyter, and deacon stands in need of reform. Rausch notes that the documents do not limit " valid " ministry to ordained ministry in communion with the historic episcopate. As for the shape of ministry in the church of tomorrow, not surprisingly, he identifies shared responsibility and collegiality as the marks of the future exercise of authority. Among the important issues still unresolved by the churches are Petrine ministry and primacy and the problem of the " reception " of ecumenical documents. The chapter on authority and reception, originally published in Theological Studies, may well be the most original contribution of the book. It broadens the discussion of reception from its historical " classical " understanding as " the acceptance by local churches of particular ecclesiastical or conciliar decisions " to an ecumenical understanding of the concept as " the acceptance by one church of a theo- 166 BOOK REVIEWS logical consensus arrived at with another church, and ultimately, the recognition of the other church's faith and ecclesial life as authentically Christian (p. 103)." He concludes that (1) reception is more properly understood as a process rather than as a juridical determination, (2) it also involves formal decisions on the part of church authorities, (3) it cannot be reduced to the acceptance of doctrinal formulations, and (4) the norm for recognizing a common faith is not agreement with a particular ecclesial position but agreement with the apostolic tradition. Ultimately, reception involves the whole church and is not the sole product of theologians or church authorities. Ecumenical dialogues will only be effective when they enter into the practical life of the churches. In "Imaging Tomorrow's Church: Models of Christian Unity" Rausch summarizes four models of church unity: organic union, conciliar fellowship, reconciled diversity, and communion of Churches. He opts for the fourth model. The chapter does not offer any new information to someone familiar with ecumenical discussions, but it does serve as an introduction for the neophyte. Rausch's image of authority in the future lies somewhere between a strictly hierarchical or institutional model and a more egalitarian model. His final chapter, " Authority in Tomorrow's Church," predicts that the church of the future will be " ordered " in the sense that it will combine an authoritative ordained ministry (based on the church's apostolic office) with a recognition of multiple and diverse charismatic gifts. He retrieves Karl Rahner's suggestion that recognition of charism for leadership in an individual may result in that person's " relative" ordination for a particular local community. Authority of the future will be collegial with a more participatory style of decision-making. The renewed papacy will encourage not only a more participatory style of decision-making but also a broader participation in the formulation of church teaching. He suggests that representatives of particular churches could elect the Bishop... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:"General Rules" in Hume's Treatise THOMAS K. HEARN, JR. IT COULDBE CONFIDENTLYASSERTED in 1925 that Hume was "no longer a living figure." x Stuart Hampshire records that when he began his philosophy studies in 1933, Hume's conclusions were regarded at Oxford as "extravagances of scepticism which no one could seriously accept." 2 That virtually no Anglo-American philosopher would now share such opinions about Hume testifies not only to (...) the general change in the philosophical climate but, in addition, it reflects a transformation which has occurred in the interpretation of Hume's philosophy. In eitecting this transformation.much credit is due to the work of Norman Kemp Smith. Kemp Smith argued that preoccupation with Hume's empiricist heritage and his scepticism had blinded scholars to the fundamentally constructive intent of his philosophy, and, indeed, that only from the perspective of his positive achievement was it possible to grasp the nature and significance of Humean scepticism. This paper, in keeping with the basic orientation of Kemp Smith, sets out a central feature in the attempt to describe and assess Hume's constructive, nonsceptical point of view: Hume attributes to general rules "a mighty influence on our actions and understanding..." (374).4 This paper examines the Treatise to show that this was not just a casual comment. To discuss the "influence" of general rules requires an examination of their character and the various aspects of "action and understanding " in which such rules function. The thesis to be developed can be stated briefly. In Book I Hume introduces two sorts of general rules which must be distinguished carefully. One type of rule describes a propensity of the imagination to extend the scope This research was supported by a grant from the National Foundation on the Arts and Humanities. x Charles W. Hendcl, Studies in the Philosophy of David Hume (New York, 1963), p. 20. (First published in 1925.) For Professor Hendel's later comments on this statement, see pp. xxi ft. "Hume's Place in Philosophy" in David Hume, ed. D. F. Pears (London, 1963), p. 3. a Proper stress is due here to the phrase "basic orientation." There is much about Kemp Smith's understanding of Hume which is mistaken in my view. 9 The page references in parentheses refer to the Svlby-Bigge edition of A Treatise o/ Human Nature (Oxford, 1888). [4o5] 406 HISTORY OF PHILOSOPHY of judgments formed in one set of circumstances to other resembling but non-identical circumstances. The other type of general rule, the discussion of which largely occupies this paper, functions to correct certain natural propensities which result in erroneous belief or action if permitted to operate unchecked. The same pattern, a natural tendency requiring correction by general rules, is exhibited in all three books of the Treatise, and can be said to represent one of the basic ingredients in Hume's account of human nature and experience. It is somewhat surprising that in a book which patiently discusses almost evcxy theme in the Treatise, Kemp Smith's study contains no discussion at all of rules. This is the more puzzling as Kemp Smith clearly recognized that by reflection the understanding supplies principles which are normative for the interpretation of experience.5 Our aim in this study is to discuss what for Hume these principles are, and, as far as possible, how they fit into the Humean account of human nature. A fuller understanding of the nature and function of such reflective principles is required to spare Kemp Smith's interpretation from a seeming inconsistency. This apparent inconsistency arises because Kemp Smith takes the slavery of reason to the passions as the "key" to his understanding of Hume, but then develops the view that for Hume reason/s a passion, in Hume's words, "a wonderful and unintelligible instinct." (179)6 The inconsistency disappears when it is recognized that Kemp Smith's account of Hume requires a more subtle and complex understanding of the role of reason than that suggested by the emphasis on the "slavery of reason" especially in the early parts of the book. This study represents a way of supplying the broader and more const,ructive understanding of reason which... (shrink)

This book contains a representationalist theory of self-consciousness and of the phenomenal first-person perspective. It draws on empirical data from the cognitive and neurosciences.

How much information from experience does a normal adult remember? The “functional information content” of human memory was estimated in several ways. The methods depend on measured rates of input and loss from very long‐ term memory and on analyses of the informational demands of human memory‐based performance. Estimates ranged around 109 bits. It is speculated that the flexible and creative retrieval of facts by humans is a function of a large ratio of “hardware” capacity to functional storage requirements.

The notion of a capacity in the sense of a power to bring about or undergo change plays a key role in Aristotle’s theories about the natural world. However, in Metaphysics Θ Aristotle also extends ‘ capacity ’, and the corresponding concept of ‘activity’, to cases where we want to say that something is in capacity, or in activity, such and such but not, or not directly, in virtue of being capable of initiating or undergoing change. This paper seeks to (...) clarify and confirm a certain view of how Aristotle wishes us to see the relationship between the two uses of ‘ capacity ’ and ‘activity’. To that end, I consider also Aristotle’s employment of the terms in the De Anima, which sheds light on the key examples which direct the discussion in Metaph. Θ. (shrink)

The current study extends previous literature regarding the effectiveness of learning about academic integrity through peer instruction by assessing the impact of a peer instructional approach for actual and perceived learning gains over time. One trained residence don provided one interactive 30-min presentation covering four major aspects of academic integrity and misconduct to groups of undergraduate students. In total, 192 participants attended the workshop and were surveyed for their knowledge of academic integrity immediately before the presentation, immediately after the presentation, (...) and after a four week delay. Perceptions regarding the presentation also were assessed. Consistent with previous literature, results indicate perceived learning gains and preference for having an interactive presentation delivered by a residence don. In addition, actual gains in knowledge were found immediately after the presentation and gains remained evident over a four-week delay. Outcomes suggest that peer instruction is a viable and effective approach for educating students about academic integrity. (shrink)

For ten years, 1971–1981, the Institute onHuman Values in Medicine (IHVM) played a keyrole in the development of Bioethics as afield. We have written this history andanalysis to bring to new generations ofBioethicists information about the developmentof their field within both the humanitiesdisciplines and the health professions. Thepioneers in medical humanities and ethics cametogether with medical professionals in thedecade of the 1960s. By the 1980s Bioethics wasa fully recognized discipline. We show the rolethat IHVM programs played in defining thefield, training (...) faculty and helping schools todevelop programs. We review the beginnings ofthe IHVM in the crucible of social andtechnological change that led to theestablishment of the IHVM's parentorganization, the Society for Health and HumanValues.

THIS paper is an effort to bring together two issues bearing on the moral philosophy of Hume. First, an effort will be made to interpret and clarify the role of general rules in Hume’s account of moral judgment. Second, the proper classification of the moral sentiments according to categories made familiar by studies in the philosophy of mind will be offered. The collective bearing of these two matters on the analysis of Hume’s moral theory will then be explored.

The hypothesis that perceptual mechanisms could have more representational and logical power than usually assumed is interesting and provocative, especially with regard to brain evolution. However, the importance of embodiment and grounding is exaggerated, and the implication that there is no highly abstract representation at all, and that human-like knowledge cannot be learned or represented without human bodies, is very doubtful. A machine-learning model, Latent Semantic Analysis (LSA) that closely mimics human word and passage meaning relations is offered as a (...) counterexample. (shrink)

In this article I caution that María Lugones's critiques of Kimberlé Crenshaw's intersectional theory posit a dangerous form of epistemic erasure, which underlies Lugones's decolonial methodology. This essay serves as a critical engagement with Lugones's essay “Radical Multiculturalism and Women of Color Feminisms” in order to uncover the decolonial lens within Crenshaw's theory of intersectionality. In her assertion that intersectionality is a “white bourgeois feminism colluding with the oppression of Women of Color,” Lugones precludes any possibility of intersectionality operating as (...) a decolonial method. Although Lugones states that her “decolonial feminism” is for all women of color, it ultimately excludes Black women, particularly with her misconstruing of Crenshaw's articulation of intersectionality that is rooted within the Black American feminist tradition. I explore Lugones's claims by juxtaposing her rendering of intersectionality with Crenshaw's and conclude that Lugones's decolonial theory risks erasing Black women from her framework. (shrink)

The claim that language is shaped by the brain is weakened by lack of clear specification of what necessary and sufficient properties the brain actually imposes. To account for human intellectual superiority, it is proposed that language did require special brain evolution (Deacon 1997), but that what evolved was a merely quantitative change rather than a radically new invention.

ABSTRACTRemembering to perform a behaviour in the future, prospective memory, is essential to ensuring that people fulfil their intentions. Prospective memory involves committing to memory a cue to action, and later recognising and acting upon the cue in the environment. Prospective memory performance is believed to be influenced by the emotionality of the cues, however the literature is fragmented and inconsistent. We conducted a systematic search to synthesise research on the influence of emotion on prospective memory. Sixty-seven effect sizes were (...) extracted from 17 articles and hypothesised effects tested using three meta-analyses. Overall, prospective memory was enhanced when positively-valenced rather than neutral cues were presented. In contrast, negatively-valenced cues did not enhance prospective memory overall, but this effect was moderated by the timing of the emotional manipulation. Prospective memory performance was improved when negatively-valenced... (shrink)

For a long time Hume's philosophical achievement was judged almost entirely by Book I of the Treatise. A major contribution of Kemp Smith's work on Hume was the insistence that the epistemological doctrines of Book I were essentially related to the ethical theory of Book III. Recent moral philosophy has found Book III to be of considerable intrinsic interest and relevance to current problems. It is now becoming apparent, however, that Hume's ethical theory is intimately bound up with the philosophy (...) of mind in Book II. This new emphasis upon the significance of Book II for Hume's ethics derives from Dr Pall S. Árdal's book Passion and Value in Hume's Treatise. In view of Árdal's influence on continuing study in this field—witness the recent book by Philip Mercer—it becomes important to point out what I take to be a major error in one part of Árdal's analysis of the relationship between Hume's philosophy of mind and his moral theory.
