This study, based chiefly on unpublished source material, shows that Thomas was very much present to both the humanists and to the academic philosophers during the Renaissance. Such leading humanists as Lorenzo Valla, Giovanni Pico della Mirandola, and Marsilio Ficino, quote St. Thomas frequently and with approval. Even the unfavorable attitudes of Ermolao Barbaro or Baptista Mantuanus show that Thomas was already the most celebrated of mediaeval philosophers.

St. Thomas made a continuous contribution to the development of Renaissance theology and philosophy.

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 249 Girolamo Balduino: Ricerche sulla logica della Scuola di Padova nel Rinascimento. By Giovanni Papuli. (Bark Lacerta, Universith di Bari, Pubblicazioni dell'lstituto di filosofia, 12, 1967. Pp. 313. no price.) The philosophers at the University of Padua during the late Middle Ages and Renaissance arc attracting much renewed interest. This study makes accessible again the logical philosophy of Girolamo Balduino, professor at Padua during the second quarter (...) of the sixteenth century. Like other thinkers of his period, 13alduino follows the logic of Aristotle, and looks for progress within the ancient and mediaeval tradition, not for radically new doctrines. He continues the traditional interpretation of Aristotle by Averroes, for whom logic is only an instrumental habitus, a tool or method of demonstration. About the final contribution of the school of Padua to the improvement of Aristotelian logic was the doctrine of regressive demonstration, where demonstration terminates in or discloses the definition. Zabarella's well-known teaching on this point seems to be derived entirely from Balduino. Contrary to the interpretation of Cassirer, followed by Randall, this regressive demonstration is not a universal method of inquiry and is not at all like, and not the historical source of, the new method of Galileo. Papuli's book is solidly based on the original Latin texts, in notes, which are of great value in view of the fact that Balduino's works have been out of print since 1573. Not all of Papuli's interpretations are beyond criticism (e.g., p. 296), but he has done a service in enabling us to reestablish contact with one of the last significant commentators on Aristotle's logic. PAUL J. W. MILLER University of Colorado Documents sur la vie de Jules-Cdsar Vanini de Taurisano. By Emile Namer. (Bari: Adriatica Editrice, n.d.=Univcrsith degli Studi di Bari, Pubblicazioni delFIstituto di Filosofia, II serie, Testi e Documenti, I. Pp. 196+22 facsimile illustrations) Giulio Cesare Vanini (1585-1619) ranks with Giordano Bruno as a modern hero of freedom of philosophical expression. He was tortured and then burned at the stake in Toulouse at the age of thirty-four, because of the unorthodoxy of his views. For this reason, he has drawn more attention than is perhaps deserved on the basis of his rather mediocre writings, which are little more than a tissue of plagiarisms culled from Pomponazzi, Cardano, J. C. Scaliger, and others. In this volume, Emile Namer has collected the scattered documents dealing with Vanini's life and activities. This is a valuable service, for it should enable scholars to disentangle fact from fiction and reality from myth. There has been so much heated discussion regarding Vanini that it is now time that someone should attempt to establish the precise facts and to reevaluate Vanini's place in intellectual history. In the past, writings about him have been governed more often by emotion than by reason. Namer prints documents from Naples, London, Paris, Simancas, and Toulouse. Some of these have been printed before in various journal articles, but it is valuable to have them all together in a single volume. In addition, he prints relevant excerpts concerning--as one of them put it--le douzi~me apostre de Satan, including material from Mersenne, Garasse, and others. He also includes a series of facsimiles of sample pages from the documents which he prints. All in all Namer's work is competently 250 HISTORY OF PHILOSOPHY done, though perhaps a bit more annotation to put the documents in historical perspective would have been desirable. In any case this little volume must be one of the bases for any future serious biographical or interpretative studies dealing with Vanini. Moreover, it shouM also be useful for scholars dealing with more general questions of seventeenth-century intellectual, religious, and social history. Unfortunately, there is no index, nor bibliography of earlier literature on Vanini, and the Introduction is perhaps too brief to orient the reader who has little previous knowledge of Vanini.

(New York: St. Martin's Press, 1968. Pp. 264. $8.50) The one thing about which Hobbes's commentators have agreed is the absence of any significant process of development in the several statements of his philosophic views. This has been most evident in their willingness to use the various texts as a common repository from which evidence for their interpretations could be drawn with little regard for its specific textual origin. Notoriously, no consensus has emerged from such endeavors and McNeilly believes this method of interpreting Hobbes far too indiscriminate. He contends that careful examination of the differing expressions and contexts of apparently recurrent arguments will show, in many cases, not the same argument repeated several times, but several different arguments. And these, properly discriminated, reveal a definite pattern of development culminating, in Leviathan, with a political theory substantially different from that of the earlier works. While the political theory of the Elements of Law and De Cive consists of a series of predictions founded on the known psychological tendencies of men, the theory of Leviathan, MeNeilly contends, is independent of any particular concept of human nature. Rather it is a "formal system of necessarily true propositions" (p. 213) constituting "a systematic analysis of value systems generally" (p. 245). Excepting two introductory chapters, the whole of McNeilly's argument is given over to substantiating this radical thesis, his point of departure being Hobbes's allegedly shifting views on method which are taken to vary somewhat inconsistently in the earlier works among self evidence, conventionalist and hypothetico-deductive theories and combinations of these. By contrast, in Leviathan, McNeilly argues, Hobbes expounds a conventionalist view with "clarity and persistence" (pp. 84-85). When this BOOK REVIEWS 479 conventionalism is combined with the adoption of mathematics as the paradigm of sound science, it leads Hobbes to the view that pohtical theory can be constructed as a formal system of necessary propositions because he believes that mathematics is about the world and extends this mistake to formal systems generally. These methodological commitments then, render any concept of human nature irrelevant to political theory. McNeilly's task in the second main section of the book is to show that in contrast to the earlier works, and contrary to all appearances, the Leviathan's account of human nature is completely neutral with regard to any possible set of motives and hence, wholly formal. Specifically he argues that materialism and mechanism play no active role in Hobbes's account of the passions and that the psychological egoism characteristic of the Elements and the fourth part of De Corpore is abandoned. (Throughout it is assumed that De Corpore was substantially complete before Leviathan was composed; this may not be true of the fourth part, as McNeilly recognizes, but he is undeterred.) The formal account of the passions in Leviathan then is formally compatible with either egoistic or nonegoistic interpretations of human motivation. Similarly, it is argued that Hobbes gives up his pessimism about men as... (shrink)

I set up two axiomatic theories of inductive support within the framework of Kolmogorovian probability theory. I call these theories ‘Popperian theories of inductive support’ because I think that their specific axioms express the core meaning of the word ‘inductive support’ as used by Popper (and, presumably, by many others, including some inductivists). As is to be expected from Popperian theories of inductive support, the main theorem of each of them is an anti-induction theorem, the stronger one of them saying, (...) in fact, that the relation of inductive support is identical with the empty relation. It seems to me that an axiomatic treatment of the idea(s) of inductive support within orthodox probability theory could be worthwhile for at least three reasons. Firstly, an axiomatic treatment demands from the builder of a theory of inductive support to state clearly in the form of specific axioms what he means by ‘inductive support’. Perhaps the discussion of the new anti-induction proofs of Karl Popper and David Miller would have been more fruitful if they had given an explicit definition of what inductive support is or should be. Secondly, an axiomatic treatment of the idea(s) of inductive support within Kolmogorovian probability theory might be accommodating to those philosophers who do not completely trust Popperian probability theory for having theorems which orthodox Kolmogorovian probability theory lacks; a transparent derivation of anti-induction theorems within a Kolmogorovian frame might bring additional persuasive power to the original anti-induction proofs of Popper and Miller, developed within the framework of Popperian probability theory. Thirdly, one of the main advantages of the axiomatic method is that it facilitates criticism of its products: the axiomatic theories. On the one hand, it is much easier than usual to check whether those statements which have been distinguished as theorems really are theorems of the theory under examination. On the other hand, after we have convinced ourselves that these statements are indeed theorems, we can take a critical look at the axioms—especially if we have a negative attitude towards one of the theorems. Since anti-induction theorems are not popular at all, the adequacy of some of the axioms they are derived from will certainly be doubted. If doubt should lead to a search for alternative axioms, sheer negative attitudes might develop into constructive criticism and even lead to new discoveries. -/- I proceed as follows. In section 1, I start with a small but sufficiently strong axiomatic theory of deductive dependence, closely following Popper and Miller (1987). In section 2, I extend that starting theory to an elementary Kolmogorovian theory of unconditional probability, which I extend, in section 3, to an elementary Kolmogorovian theory of conditional probability, which in its turn gets extended, in section 4, to a standard theory of probabilistic dependence, which also gets extended, in section 5, to a standard theory of probabilistic support, the main theorem of which will be a theorem about the incompatibility of probabilistic support and deductive independence. In section 6, I extend the theory of probabilistic support to a weak Popperian theory of inductive support, which I extend, in section 7, to a strong Popperian theory of inductive support. In section 8, I reconsider Popper's anti-inductivist theses in the light of the anti-induction theorems. I conclude the paper with a short discussion of possible objections to our anti-induction theorems, paying special attention to the topic of deductive relevance, which has so far been neglected in the discussion of the anti-induction proofs of Popper and Miller.

Commonsense reasoning about the physical world, as exemplified by "Iron sinks in water" or "If a ball is dropped it gains speed," will be indispensable in future programs. We argue that to make such predictions (namely, envisioning), programs should use abstract entities (such as the gravitational field), principles (such as the principle of superposition), and laws (such as the conservation of energy) of physics for representation and reasoning. These arguments are in accord with a recent study in physics instruction where (...) expert problem solving is related to the construction of physical representations that contain fictitious, imagined entities such as forces and momenta (Larkin 1983). We give several examples showing the power of physical representations. (shrink)

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

The western-based leadership and ethics literatures were reviewed to identify the key characteristics that conceptually define what it means to be an ethical leader. Data from the Global Leadership and Organizational Effectiveness (GLOBE) project were then used to analyze the degree to which four aspects of ethical leadership – Character/Integrity, Altruism, Collective Motivation, and Encouragement – were endorsed as important for effective leadership across cultures. First, using multi-group confirmatory factor analyses measurement equivalence of the ethical leadership scales was found, which (...) provides indication that the four dimensions have similar meaning across cultures. Then, using analysis of variance (ANOVA) tests each of the four dimensions were found to be universally endorsed as important for effective leadership. However, cultures also varied significantly in the degree of endorsement for each dimension. In the increasingly global business environment, these findings have implications for organizations implementing ethics programs across cultures and preparing leaders for expatriate assignments.

Both texts defend a thoroughly un-Aristotelian conception of place as three-dimensional space. Odonis not only deviates from Aristotle's definition of place as the inner surface of a surrounding body, but also from the positions of his contemporaries, including fellow Franciscans. Despite some remarkable doctrinal similarities between Odonis' view and that (...) of Renaissance innovators like Francesco Patrizi and Bernardino Telesio, it seems unlikely that Gerald played a role in the rise of new conceptions of place in the sixteenth and seventeenth century.
