J.W. Olson addresses the Christian doctrine of revelation by asking how theological truth claims can possibly be rooted in God’s incarnational self-communication. Engaging with the phenomenology of Martin Heidegger, Olson offers an interpretation of the Eucharist that grounds Christian knowledge in an embodied understanding of the sacrament.

ABSTRACT This essay explores the possibility for a phenomenology of Christian vocational calling through conversation with Jean-Paul Sartre’s existential-ontology. By demonstrating how Sartre’s account of nothingness comports with a Rahnerian understanding of God as absolute mystery and how Sartre’s account of bad faith further opens up an understanding of ontological self-identity as a turn away from God, we can establish a phenomenology of Christian vocation as one’s owning each finite situation in terms of its divinely available possibilities rather than simply (...) its given conditions. Divine call thus occurs where one’s possibilities for boundless becoming are freely recognized in any situation and are further apprehended in light of the character of God to become the possibilities for the freedom and calling of others.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 33.2 (2000) 182-186 [Access article in PDF] Book Review Rhetoric and Community: Studies in Unity and Fragmentation Rhetoric and Community: Studies in Unity and Fragmentation. Studies in Rhetoric/Communication. Ed. J. Michael Hogan. Series ed. Thomas W. Benson. Columbia, SC: U of South Carolina P, 1998. Pp. xxxviii + 315. $39.95. Based on papers and critical responses presented at the Fourth Biennial Public Address Conference, which was (...) held at Indiana University in 1994, this collection of fourteen essays by leading rhetoric scholars concentrates on the relationships among rhetoric, community, and fragmentation. Organized into three broad sections entitled "Race, Gender, and Community," "War and Community," and "Artistic and Scientific Community," the book contributes to ongoing conversations about the roles of language, symbolism, differences, metaphors, myths, hegemony, economic class, pluralism, and multiple consciousness in unifying the United States. A preface and a conclusion by J. Michael Hogan, who edited the collection, provides an orientation and summary for this new volume in the University of South Carolina Press series devoted to Studies in Rhetoric/Communication.The preface frames the book's contribution as a response to a belief that "a growing number of social and political commentators fear that the United States has lost all sense of 'community'--that repository of shared purpose, values, and traditions which historically has defined the American character" (xii). Hogan amplifies, "The signs of stress and fragmentation appear everywhere, not just in our national political and cultural dialogue but in all of the various communities that define our social lives--our families, our neighborhoods, our towns and cities, our professions, and our social and cultural associations" (xii). The preface situates the book in this concern about a "lost" unity that once upon a time typified the United States. But this "lost" community is a mythic representation of a past that has never existed in the United States, except possibly in the imaginations of people habituated to dominant roles. Stephen H. Browne's comments about restoration projects in general are germane: "The work of restoration has [End Page 182] never come easy for Americans, not least of all because it presumes a state that never existed and the appeal to which is almost always self-interested" (75).Describing the fourteen contributors as sharing "a common bond," Hogan asserts, "recognizing that communities are largely defined, and rendered healthy or dysfunctional, by the language they use to characterize both themselves and others, all share an abiding concern with how communities are constituted and sustained--or, in some cases, threatened and disrupted--by the words their leaders choose to characterize both themselves and others" (xv). Hogan emphasizes a question that he reiterates with slight changes in the conclusion: "Can feminist or ethnic and racial communities successfully sustain and celebrate their own identities without alienating themselves from the larger community?" (295; similarly, xxiii). But if all members of a community are responsible for unity and fragmentation, if we are unwilling to assign responsibility for fragmentation to subordinated community members, it may be necessary, consciously, to reverse the dynamics of power implicit in Hogan's question, by asking: "Can groups that have had a history of dominating others--both beyond and within the borders--sustain their own identities and still relate productively to the community?" In addition, because the English language is a communal inheritance, it may be revealing to ask, in a reversal of the book's focus on "community," how are notions of individualism sustained in the United States?Roderick P. Hart's introduction, "Community by Negation--An Agenda for Rhetorical Inquiry," focuses on a rhetoric of hate as practiced by both the political right and the political left. Hart inquires "whether it is possible to have community without hate" (xxv). This question is necessary in any serious discussion of rhetoric, fragmentation, and community; yet calculated opportunism and economic exploitation may be misnamed and obfuscated in language depicting a rhetoric of "hate." Indeed, Lu-in Wang, a legal scholar, suggests that these other motives may be more common than animus in so-called "hate crimes." Live interviews with convicted killers... (shrink)

Reanimated for the contemporary literature in the writings of Quine, [16]) and Kuhn [7], the conventionalism of Duhem [2] and Poincaré [12] has emerged in the last few years as one of the genuinely interesting topics in the philosophy of science. The theory in question—let us follow Grünbaum [3] in calling it the D-thesis, after its founder, Pierre Duhem—claims three things: a single scientific hypothesis H is never disconfirmable in isolation from its fellow; every single hypothesis H of science presupposes, (...) explicitly or implicitly, the support of a conjunction A = A, • A2 • … • Am of auxiliary assumptions or hypotheses; the failure of an observational consequence of H in face of contradictory evidence disconfirms only the conjunction of H and A, not H alone—i.e. establishes only ∼. The logical picture is as follows. (shrink)

I wish to thank Klaus Kühnle who streamlined in [8] several of my definitions and proofs concerning the subject matter of this paper. Some ideas and results arose from discussions with Klaus Leeb. Jan Johannsen discovered some mistakes in an earlier version.

My reason for bringing up the familiar matter of phenomenalism is both critical and historical. Almost to a man those who have been interested in arguing for or against phenomenalism have assumed that Berkeley was a phenomenalist. Now if Berkeley's doctrine is appropriately named “phenomenalism,” then it is a phenomenalism of a quite different stripe from the twentieth century variety, though many who have described his doctrine as phenomenalism have not sufficiently stressed the difference.

Although the theory of definability had many important antecedents—such as the descriptive set theory initiated by the French semi-intuitionists in the early 1900s—the main ideas were first laid out in precise mathematical terms by Alfred Tarski beginning in 1929. We review here the basic notions of languages, explicit definability, and grammatical complexity, and emphasize common themes in the theories of definability for four important languages underlying, respectively, descriptive set theory, recursive function theory, classical pure logic, and finite-universe logic. We review (...) the history of previous studies of the similarities and differences in the theories of definability of the first three of these four languages. A seminal role leading toward unification of the theories has been played by the separation principles introduced by Nikolai Luzin in 1927. Emphasizing analogies and driving toward further unification embracing finite-universe logic we concentrate on a simple example—the first and second separation principles for existential-universal first-order sentences . Using this as a test case for the fundamental problem of how to “finitize” arguments in classical pure logic to the finite-universe case, we are led to the analogous negative solution by using the theory of certain special graphs: a graph is - special for any positive integers m , n , p , q iff it is bipartite with m red points and n blue points and for every p -tuple of red points there is a blue point to which they are all connected . As an aside we introduce for further study a natural “Ramseyesque” increasing sequence A of positive integers, where A is the least positive integer n for which an -special graph exists. (shrink)

Recently a growing number of biologists have begun to consider the causal role that processes of embryonic development may play in evolution. This constitutes a reunion of these phenomena which had been linked in the nineteenth century through Haeckel's biogenetic law. This reunion may result in a new subdiscipline of biology, if there is a set of unique concepts and methods which tie the various research approaches together. Such concepts as bauplan, canalization, and developmental constraint, may serve in such a (...) capacity. The methods employed must combine comparative and experimental analyses, with special attention paid to the range of variation in developmental events within each taxon. These concepts and methods are also applicable to the problem of how development evolved, thus the evolution of development may also be considered part of the reunion. The reunion is discussed in terms of the potential participation of various schools of thought found in the current literature. (shrink)

The purpose of this brief introduction is to describe the origin of the papers here presented and to acknowledge the help of some of the many individuals who were involved in the preparation of this volume. Of the eighteen papers, nine stem from the annual fall colloquium of the Depart ment of Philosophy at the University of Western Ontario held in London, Ontario from November 10 to November 12, 1967. The colloquium was entitled 'Philosophical Logic'. After some discussion, the editors (...) decided to retain that title for this volume. Von Wright's paper 'On the Logic and Ontology of Norms' is printed here after some revision. A. R. Anderson commented on the paper at the colloquium, but his comments here are based upon the revised version of the von Wright paper. The chairman of the session at which von Wright's paper was read and discussed was T. A. Goudge. Aqvist's paper 'Scattered Topics in Interrogative Logic', and Belnap's comments, 'Aqvist's Cor rections-Accumulating Question-Sequences', are printed as delivered. The chairman of the Aqvist-Belnap session was R. E. Butts. Wilfrid Sellars' paper 'Some Problems about Belief' is printed as delivered at the col loquium, but 'Quantifiers, Beliefs, and Sellars' by Ernest Sosa is a revision of his comments at the colloquium. That session was chaired by G. D. W. Berry. Ackermann's paper 'Some Problems oflnductive Logic', as well as Skyrms' comments, are printed as delivered. (shrink)

For each regular cardinal κ, we set up three systems of infinitary type logic, in which the length of the types and the length of the typed syntactical constructs are $\Sigma _{}$, the global system $\text{g}\Sigma _{}$ and the τ-system $\tau \Sigma _{}$. A full cut elimination theorem is proved for the local systems, and about the τ-systems we prove that they admit cut-free proofs for sequents in the τ-free language common to the local and global systems. These two results (...) follow from semantic completeness proofs. Thus every sequent provable in a global system has a cut-free proof in the corresponding τ-systems. It is, however, an open question whether the global systems in themselves admit cut elimination. (shrink)

We propose the beginnings of an intuitionistic propopsitional dynamic logic, and describe several serious open problems.

Definitions are traditionally seen as abbreviations, as tools for notational convenience that do not increase inferential power. From a Philosophy of Mathematical Practice point of view, however, there is much more to definitions. For example, definitions can play a role in problem solving, definitions can contribute to understanding, sometimes equivalent definitions are appreciated differently, and so on. This chapter reviews the literature on definitions and (to a certain extent) concepts in mathematical practice. It is structured according to four themes through (...) which definitions (and concepts) in mathematical practice have been studied. These themes concern (1) the nature of definitions, (2) whether and how concepts evolve, (3) definitions and concepts from a communal perspective, and (4) different values relating to definitions and concepts.

This presentation of the main phases and features of political thought in the sixteenth century is based on an exhaustive study of contemporary writings in Latin, English, French, German and Italian. The book is divided into four parts. The first part deals with the new thought of Protestantism. The rest describes special ideas that emerged in England, France and Italy.
