Criticism of the deductive model of explanation continues. In a recent article, “Truisms as the Grounds for Historical Explanations,” Professor Michael Scriven hangs a great many critical points from the distinction between explanations and their justifications. I should like to examine his proposal with a view to showing that in so far as this distinction can be made, it cannot be used as a basis of criticisms of the deductive or covering law model, as it was originally outlined by Professor (...) Carl G. Hempel. (shrink)

The author assesses the complicated issues surrounding the value of Plato's dialogues in college education, offering an historical and textual account of why Plato is readily adopted into the American undergraduate curriculum. Despite this acceptance, students in the classroom often read Platonic dialogues as a body of metaphors instead of a site of significant and practical knowledge. Instructors also frequently emphasize the life of Plato over the philosophical and educational dimensions of the dialogues. The author addresses the educational benefits of (...) reading Plato specifically in terms of how Plato is read in class and the effects of this reading on students’ learning processes. The author offers the example of the Meno, which can instill in students an understanding of education based on knowledge of habit, of the acquisition of skills, and of the process of overcoming intellectual blindness. However, these important pedagogical benefits can be lost if the dialogue is read as a piece of literature or as merely offering insightful metaphors. Thus, the educational value of Plato depends entirely on how Plato is taught, the pedagogical goals of an instructor, and the engagement of students with the material. (shrink)

Philosophic reflection should consider more and different kinds of historical writing than it generally has; the logical features of cultural and intellectual history are important. Certain highly selected features of products of human activities-not individuals or actions-are the subject matter of typical instances of intellectual history; and these features are singled out by the historian's abstracting imagination. In the "stories" which such historians tell, not only are events placed in sequential order, but the relation of reasons to products are traced (...) above all in such a way as to show how some later result is composed of various earlier components. Causality is not the central unifying theme; tracing the relations that hold among the features of various human products is worthwhile even where knowledge of causes remains obscure. (shrink)

SummaryIn the first part of the paper necessary conditions for the rationality of the notions of belief, knowledge, and assumption are given: Among the different conditions it is stressed that one needs two different concepts of belief, one such that if someone knows something he also believes it, the other exclusive such that if someone knows something he need not to believe it and if he believes it he does not yet know it. Another important point is that deductive infallibility (...) has to be rejected as not being a property of human rationality. Similarly it is not a property of human rationality to know all logical true statements.The second chapter offers a deductive system which meets these and additional conditions of human rationality. The third chapter contains the semantics of the deductive system.RésuméDans le premier chapitre ľauteur énumére des conditions nécessaires à la rationalité des concepts croire, savoir et admettre. Entre autres, il relève qu'il faut distinguer au moins deux concepts croire, qui satisfont ľun àľénoncé: quand quelqu'un sait quelque chose, il la croit aussi, ľautre plus exclusif à: quand quelqu'un sait quelque chose, il n'a pas besoin de la croire et quand quelqu'un la croit , il ne la sait pas . Un autre point très important est que ľinfaillibilité déductive doit être rejetée comme n'appartenant pas à la rationalité humaine. Idem pour la connaissance de tous les énoncés logiquement vrais.Le deuxième chapitre décrit un système déductif qui remplit ces conditions de rationalité . Le troisième, la sémantique de ce système.ZusammenfassungIm ersten Kapitel werden notwendige Bedingungen für die Rationalität der Begriffe Glauben, Wissen und Annehmen gegeben: Unter anderem wird hervorgehoben, dass minde‐stens zwei verschiedene Begriffe von Glauben nötig sind; einmal so, dass gilt: wenn einer etwas weiss, dann glaubt er es auch, und dann auch im exklusiven Sinn: wenn einer etwas weiss, dann braucht er es nicht zu glauben und wenn einer etwas glaubt, dann weiss er es nicht. Ein anderer sehr wichtiger Punkt ist, dass deduktive Infallibilität (d.h. dass man von dem. (shrink)

This presentation uses the by-now customary division of philosophy of history into speculative and critical philosophy, devoting a volume to each. The text is mainly excerpts from the philosophers under study, with brief interpretative comments preceding the text and selected bibliographies following. The excerpts are generally well chosen and can be read with profit by those seeking an introduction to philosophy of history, as well as by more advanced students. The interpretations in a number of cases suffer from one-sidedness, especially (...) in the cases of Hegel and Marx. There are also some careless errors, the most glaring being the switching of the meaning of the German terms, Historie and Geschichte. The speculative philosophies of history are excerpted from Augustine, Vico, Kant, Hegel, Marx, Spengler, and Toynbee. There is also an interesting excerpt from Herder. The critical philosophies of history consist of selections from Comte, Mill, Dilthey, Collingwood, Walsh, Hempel, Dray, Mandelbaum, Weingartner, Beard, Becker, Nagel, Aron, Hook and Berlin. The inclusion of such a diversified and conflicting group of philosophies under the common heading of "critical philosophy" makes for an uneasy and tight fit. The final essay in Volume II is by Georges Florovsky, "The Study of the Past" and it appears in a chapter entitled "Conclusion"--all of which is a little puzzling, since Florovsky is presenting a theology of history as distinct from a philosophy of history.--H.

The present article shows that there are consistent and decidable manyvalued systems of propositional logic which satisfy two or all the three criteria for non-trivial inconsistent theories by da Costa . The weaker one of these paraconsistent system is also able to avoid a series of paradoxes which come up when classical logic is applied to empirical sciences. These paraconsistent systems are based on a 6-valued system of propositional logic for avoiding difficulties in several domains of empirical science ).

The contributions to this volume are from participants of the international conference "Kreisel's Interests - On the Foundations of Logic and Mathematics", which took place from 13 to 14 2018 at the University of Salzburg in Salzburg, Austria. The contributions have been revised and partially extended. Among the contributors are Akihiro Kanamori, Göran Sundholm, Ulrich Kohlenbach, Charles Parsons, Daniel Isaacson, and Kenneth Derus. The contributions cover the discussions between Kreisel and Wittgenstein on philosophy of mathematics, Kreisel's Dictum, proof theory, the (...) discussions between Kreisel and Gödel on philosophy of mathematics, some bibliographical facts, and a collection of extracts from Kreisel's letters.

In this paper it is shown that, in spite of their intuitive starting points, Kuipers' accounts lead to counterintuitive consequences. The counterintuitive results of Kuipers' account of H-D confirmation stem from the fact that Kuipers explicates a concept of partial (as opposed to full) confirmation. It is shown that Schurz-Weingartner's relevant-element approach as well as Gemes' content-part approach provide an account of full confirmation that does not lead to these counterintuitive results. One of the unwelcome results of Kuipers' account (...) of nomic truthlikeness is the consequence that a theory Y, in order to be more truthlike than a theory X (where Y and X are incompatible), must imply the entire nomic truth. It is shown how the relevant-element approach to truthlikeness avoids this result. (shrink)

The volume deals with the history of logic, the question of the nature of logic, the relation of logic and mathematics, modal or alternative logics (many-valued, relevant, paraconsistent logics) and their relations, including translatability, to classical logic in the Fregean and Russellian sense, and, more generally, the aim or aims of philosophy of logic and mathematics. Also explored are several problems concerning the concept of definition, non-designating terms, the interdependence of quantifiers, and the idea of an assertion sign. The contributions (...) concerned with Wittgenstein's investigations into the philosophy of logic and mathematics pursue issues relating to logical necessity, the undeniability of the law of the excluded middle, and the source of self-evidence, often characterized in the literature as the "rule-following considerations". Additionally, they examine Wittgenstein's attitudes towards the very idea of set-theory as a possible foundation for arithmetic. The volume also includes a number of contributions on specific issues concerning Wittgenstein's views on moral and religious judgements. (shrink)
