The concept of truth arguably plays a central role in many areas of philosophical theorizing. Yet, what seems to be one of the most fundamental principles governing that concept, i.e. the equivalence between P and , is inconsistent in full classical logic, as shown by the semantic paradoxes. I propose a new solution to those paradoxes, based on a principled revision of classical logic. Technically, the key idea consists in the rejection of the unrestricted validity of the structural principle of (...) contraction. I first motivate philosophically this idea with the metaphysical picture of the states-of-affairs expressed by paradoxical sentences as being distinctively . I then proceed to demonstrate that the theory of truth resulting from this metaphysical picture is, in many philosophically interesting respects, surprisingly stronger than most other theories of truth endorsing the equivalence between P and (for example, the theory vindicates the validity of the traditional laws of excluded middle and of non-contradiction, and also vindicates the traditional constraint of truth preservation on logical consequence). I conclude by proving a cutelimination theorem that shows the consistency of the theory. (shrink)

In a series of very influential works, Tim Williamson has advanced and defended a much discussed theory of evidence containing, among other claims, the thesis that, if one knows P, P is part of one's evidence. I argue that K ⊆ E is false, and indeed that it is so for a reason that Williamson himself essentially provides in arguing against the thesis that, if one has a justified true belief in P, P is part of one's evidence: together with (...) a very plausible principle governing the acquisition of knowledge by non-deductive inference based on evidence, K ⊆ E leads, in a sorites-like fashion, to what would seem a series of unacceptably bootstrapping expansions of one's evidence. I then develop some considerations about the functions of and conditions for evidence which are suggested by the argument against K ⊆ E. I close by discussing the relationship of the argument with anti-closure arguments of the style exemplified by the preface paradox: I contend that, if closure is assumed, it is extremely plausible to expect that the diagnosis of what goes wrong in the preface-paradox-style argument cannot be used to block my own argument.

The paper discusses some ways in which vagueness and its phenomena may be thought to impose certain limits on our knowledge and, more specifically, may be thought to bear on the traditional philosophical idea that certain domains of facts are luminous, i.e., roughly, fully open to our view. The discussion focuses on a very influential argument to the effect that almost no such interesting domains exist. Many commentators have felt that the vagueness unavoidably inherent in the description of the facts (...) that are best candidates for being luminous plays an illicit role in such argument. The paper centres around the idea that vagueness brings with itself the prima facie plausibility of soritical principles. Using the diagnostics of sharpenings, it is first pointed out that, despite certain considerations to the contrary, the margin‐for‐error principle required by the anti‐luminosity argument may well derive all of its plausibility from an underlying soritical principle. The notion of confidence that is relevant to the argument is then isolated and sharply distinguished from the notion of subjective probability. Against this background, it is argued that the reasoning about confidence involved in the argument in favour of the problematic margin‐for‐error principle is fallacious in the same way in which sorites reasoning is. This reveals the possibility of having reliable knowledge even at the penumbral limit with falsity, a possibility for which a concrete formal model is constructed. The model in turn permits a deeper appreciation of the role played in the dialectic by the distinction between confidence and subjective probability as well as by confidence requirements on knowledge. It is concluded that careful heeding of vagueness and its phenomena, far from forcing new and surprising limits on our knowledge, actually removes one of the main barriers – unreliability – often thought to stand in its way.

A moving cultural biography of abolitionist martyr John Brown, by one of the most important African-American intellectuals of the twentieth century. In the history of slavery and its legacy, John Brown looms large as a hero whose deeds partly precipitated the Civil War. As Frederick Douglass wrote: "When John Brown stretched forth his arm... the clash of arms was at hand." DuBois's biography brings Brown stirringly to life and is a neglected classic.

Tutte le dottrine tradizionali, da quelle più arcaiche e "primitive" a quelle più evolute e articolate, hanno sempre affermato che l'uomo non è un essere solamente corporeo, sia pur dotato di ingegno e di intelligenza, ma è un essere dalla natura composita, formato da una parte materiale e da una o più componenti invisibili e "sottili" e che in lui risiede un principio immortale di origine divina o comunque soprannaturale. Secondo il modo di vedere tradizionale, l'uomo, per conoscere e realizzare (...) se stesso, deve pertanto prendere coscienza, in primo luogo ed essenzialmente, di questa sua natura di essere composito e immortale, e questa è una di quelle idee universali (per noi forse la più importante) che troviamo diffuse presso tutte le popolazioni del pianeta, anche se con sfumature diverse nelle varie tradizioni..."--Cover flap.

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 493 La Trinite Creatrice. By GILLES EMERY. Paris: Vrin, 1995. Pp. 590 (paper). It was only a question of when, not if, the late rejection of Thomism in Catholic circles would be followed by the next tum toward the thought of the Angelic Doctor. This movement is already underway, and on the European continent two groups of young Dominicans are playing prominent roles. In Toulouse, though he (...) only assumed its editorship in 1991, S.-T. Bonino already has made the venerable Revue thomiste indispensable reading again. Two recent thematic issues are especially noteworthy: "Autour d'Etienne Gilson" (94 [1994): 355-553) and "S. Thomas et l'onto-theologie" (95 [1995): 1-192). Bonino's own bulletins et recensions are erudite and lively, and he is very clear about the present situation: After the decline of the last decades, Thomism is searching for a new 6lan, a new look, and not without success:... the corpse of Thomism is stirring again. Though the new look is not yet complete, one feature is set: One common point unites all now approaching the works of St. Thomas, whatever their ultimate goals: the necessity to put Thomistic doctrine into serious historical perspective.... Historical-doctrinal study of St. Thomas is opening the possibility of an authentic revival of Thomism. (Revue thomiste 95 [1995]: 485-6) While Anglo-Americans approaching Aquinas from neoscholastic or analytic perspectives might not be so enthusiastic about history, Fr. Bonino is simply correct. For evidence, he turns to the historical work of the other group of Dominicans, at Fribourg. Chief among them is J.-P. Torrell, whose masterful 1993 biography, Initiation d saint Thomas d'Aquin, is now in English, and was accompanied by a Festschrift for the eminent professor of theologyOrdo sapientiae et amoris, ed. C.-J. de Oliveira. Not least among Torrell's contributions has been to direct the thesis of Gilles Emery-La Trinite creatrice. One paragraph of Emery's helpful general conclusion reveals three dominant themes in his important work: In virtue of the nexus mysteriorum, faith in the Trinity clarifies faith in the creative and saving activity of God, while the doctrine of creation in its turn clarifies our approach to the mystery of the Trinity. It is this mutual clarification and support among the articles of faith that we mean by speaking of the "function" of the theme of the creative Trinity. The unity of the Trinity in its works ad extra constitutes a fundamental rule of the trinitarian theology of our scholastics. But it does not exhaust their theological discourse on the subject of God as creator. To arrive at a balanced doctrine, trying to give all the aspects of the mystery their due, one must add to the rule of unity a second rule, which completes it: the procession of the divine persons is the origin of the procession of creatures. (519) Emery's primary theme is captured in the title-The Creative Trinity. Creation involves not only the one God as efficient cause bestowing existence 494 BOOK REVIEWS on a multitude of creatures (rule 1), but also the Trinitarian multiplicity within God as exemplar cause of the procession of creatures (rule 2). The neoscholastics ignored rule 2, separating creation (which was turned over to the philosophers) from Trinity (the exclusive domain of the theologians). This too neat division oflabor produced unhappy consequences: a doctrine ofcreation with no role for the Trinity, and a doctrine of the Trinity with no function in creation. What can be called Emery's Trinitarian theme is a corrective for such mistakes. To understand this side of creation rightly, Emery situates Aquinas's thought in relation to Albert and Bonaventure, on whom he heavily depends. This is his hi,storical theme. From the development of these two principal themes there gradually emerges a third, less overt, but in the long run of signal importance for the new look of Thomism-what might be called the integration theme, uniting reason and revelation in Aquinas's theology. To break through the crust that had built up around Aquinas's genuine doctrine of creation Emery turns to history. Limiting himself to the Scriptum super libros Sententiarum, he finds the Trinitarian... (shrink)

Academic freedom has become the enemy of the individual professors working in colleges and universities across the United States. Despite its historical (and maybe even essential) roots in the First Amendment, contemporary case law has consistently shown that professors, unlike most members of society, have no rights to free speech on their respective campuses. (Ironically, this is especially true on our State campuses.) Outlined is the dramatic change in the history of the courts from recognizing “academic freedom” as a construct (...) needed to protect professors from the status quo, to the abuse of “academic freedom” appropriated to protect the institution from “undesirable” professorial actions such as politically incorrect speech or research. Klein warns all those in the academy to become familiar with this pernicious 180-degree turn in the use of the “academic freedom” construct. (shrink)

Some data from earlier work concerning the evolutionary correlation of anthophilous insects, entomophilous plants, herbivorous animals, and natural soil groups are briefly summarized. Presumed successive evolution of plant and animal communities from the early Paleozoic era to the more recent formation of prairies, steppes and other grassland areas is described and pictured in Fig. 6. A definite correlation has been found among the coevolution of flowering plants, pollinating insects, ruminant animals and fertility grades of natural soil groups .Plants, insects, animals (...) and soil are interrelated in evolution as reciprocal selective and regulating factors in certain biotic and abiotic environments. This complex system can be better studied by application of the coenogenic concept and hologenic and syngenic methods.Various stages of the development of an agricultural environment in the prairie areas of the North American plains are briefly described and illustrated in Plates I–VII. A new radical change in the development by the introduction of so-called “Circle Farming” is pictured in Plates VIII–IX. This new irrigated farming system is not only profitable for the increasing of yields, but promises to some extent the restoration of a biologically balanced environment in an extensively cultivated agricultural landscape.

_Seeing the World through Children’s Eyes_ brings an overarching emphasis on ‘seeing’ to early years research and provides an opportunity to see and hear from leading researchers in the field concerning how they work with visual methodologies in their early years research.

The Congregation for the Doctrine of the Faith, under the prefecture of Joseph Ratzinger, published its instruction Donum vitae in 1987 to provide moral guidance on bioethical issues. Since 1987, many new ethical issues have arisen, especially in the areas of regenerative medicine (which includes stem cellresearch) and assisted reproduction. To address these the CDF, under the prefecture of William Levada, published the bioethical instruction Dignitas personae inDecember 2008. The present symposium includes reflections on the strengths and weaknesses of the (...) new document by six moral theologians noted for theirwork in bioethics: Christian Brugger, John Finnis, Luke Gormally, Christopher Kaczor, William E. May, and Peter F. Ryan, S.J. National Catholic Bioethics Quarterly 9.3 (Autumn 2009): 461–483. (shrink)
