In this paper we discuss two approaches to the axiomatization of scientific theories in the context of the so called semantic approach, according to which (roughly) a theory can be seen as a class of models. The two approaches are associated respectively to Suppes’ and to da Costa and Chuaqui’s works. We argue that theories can be developed both in a way more akin to the usual mathematical practice (Suppes), in an informal set theoretical environment, writing the set theoretical predicate (...) in the language of set theory itself or, more rigorously (da Costa and Chuaqui), by employing formal languages that help us in writing the postulates to define a class of structures. Both approaches are called internal , for we work within a mathematical framework, here taken to be first-order ZFC. We contrast these approaches with an external one, here discussed briefly. We argue that each one has its strong and weak points, whose discussion is relevant for the philosophical foundations of science. (shrink)

Neste artigo, a partir de tópicos presentes na obra de Newton C. A. da Costa, propomos uma fundamentação rigorosa para de uma possível formulação de teorias científicas através da abordagem semântica. Seguindo da Costa, primeiramente desenvolveremos uma teoria geral das estruturas; no contexto desta teoria de estruturas mostraremos como caracterizar linguagens formais como um tipo particular de estrutura, mais especificamente, como uma álgebra livre. Em seguida, discutiremos como associar uma linguagem a uma estrutura, com a qual poderemos formular axiomas que (...) buscam captar a teoria da estrutura. Por fim, mostraremos como podemos, utilizando este aparato conceitual, fundamentar a formalização de da Costa e Chuaqui do chamado predicado de Suppes, utilizado para caracterizar teorias científicas de modo rigoroso.

In this paper, gathering several topics present in the work of Newton da Costa, we propose a rigorous foundation for a possible formulation of scientific theories according to the semantic approach. Following da Costa, as a first step we develop a general theory of structures; inside this theory we show how we can characterize formal languages as particular kinds of structures, more specifically, as free algebras. Next we discuss how we can link a language to a structure, with which we (...) can formulate the axioms that are intended to capture the theory of the structure. Finally, we show how we can, employing the framework developed, formulate da Costa and Chaqui’s formalization of the so-called Suppes’ Predicate, used to characterize scientific theories in a rigorous way. • DOI:10.5007/1808-1711.2010v14n1p15.

Taking as its point of departure a sharp critique of Rawls's influential A Theory of Justice, this book looks at politics from an aesthetic perspective.

Why are we interested in history at all? Why do we feel the need to distinguish between past and present? In this book, the author argues that the past originates from an experience of rupture separating past and present. Think of the radical rupture with Europe's past that was effected by the French and the Industrial Revolutions. Sublime Historical Experience investigates how the notion of sublime historical experience complicates and challenges existing conceptions of language, truth, and knowledge. These experiences of (...) rupture are paradoxical since they involve both the separation of past and present and, at the same time, the effort to overcome this separation in terms of historical knowledge. The experience unites feelings of loss/pain with those of love/satisfaction, and thus is in agreement with how sublime experience is ordinarily defined. The experience is also precognitive since it precedes historical knowledge. As such it is a challenge to traditional conceptions of the relationship between experience and truth or language. It compels us to disconnect the notions of experience and truth. (shrink)

Transplantation of vital organs has been premised ethically and legally on "the dead donor rule" (DDR)—the requirement that donors are determined to be dead before these organs are procured. Nevertheless, scholars have argued cogently that donors of vital organs, including those diagnosed as "brain dead" and those declared dead according to cardiopulmonary criteria, are not in fact dead at the time that vital organs are being procured. In this article, we challenge the normative rationale for the DDR by rejecting the (...) underlying premise that it is necessarily wrong for physicians to cause the death of patients and the claim that abandoning this rule would exploit vulnerable patients. We contend that it is ethical to procure vital organs from living patients sustained on life support prior to treatment withdrawal, provided that there is valid consent for both withdrawing treatment and organ donation. However, the conservatism of medical ethics and practical concerns make it doubtful that the DDR will be abandoned in the near future. This leaves the current practice of organ transplantation based on the "moral fiction" that donors are dead when vital organs are procured. (shrink)

This book is the 1906 second edition of the Hulsean Lectures delivered at the University of Cambridge between 1901 and 1902. In these four lectures, F. R. Tennant challenges conventional teachings on Original Sin and the story of the Fall, arguing that his contemporaries had misinterpreted the biblical presentation of sin and its manifestations. Tennant aims to redefine the sin of both the race and the individual, and in doing so engages with traducianism and the philosophies of Malebranche, Kant and (...) Hegel. He argues that action predates modern conceptions of right and wrong, and that transgression is only sin if the actor is aware of what is morally right. Of course, these theories were met with great opposition, an opposition which Tennant uses the preface of this second edition to confront. These fascinating lectures and their appendages will be of great interest to scholars of Christian theology and the fin de siècle alike. (shrink)

We no longer have any texts, any past, but just interpretations of them. The evident multi -interpretability of a text causes it gradually to lose its capacity to function as arbiter in the historical debate. It is necessary to define a new link with the past based on a complete and honest recognition of the position in which we now see ourselves placed as historians. In recent years, many people have observed our changed attitude towards the phenomenon of information. For (...) postmodernism, science and information are independent objects of study which obey their own laws. Language and art are not situated opposite reality but are themselves a pseudo-reality and are therefore situated within reality. Because of the relation between the historiographical view and the language used by the historian to express his view - a relation which nowhere intersects the domain of the past -historiography possesses the same opacity and intensional dimension as art. The essence of postmodernism is precisely that we should avoid pointing out essentialist patterns in the past. There is reason to assume that our relation to the past and our insight into it will in future be of a metaphorical nature rather than a literal one. (shrink)

There are no dictionary meanings or authoritative discussions of "presence" that fix the significance of this word in a way that ought to be accepted by anybody using it. So we are in the welcome possession of great freedom to maneuver when using the term. In fact, the only feasible requirement for its use is that it should maximally contribute to our understanding of the humanities. When trying to satisfy this requirement I shall relate "presence" to representation. Then I focus (...) on a variant of representation in which the past is allowed to travel to the present as a kind of "stowaway" , so that the past is literally "present" in historical representation. I appeal to Runia's notion of so-called "parallel processes" for an analysis of this variant of historical representation. (shrink)

"The chief business of twentieth-century philosophy” is “to reckon with twentieth-century history," claimed R. G. Collingwood. In this remarkable collection of essays, Frank Ankersmit demonstrates the prescience of that remark and goes a long way toward meeting its challenge. Responding to the work of Hayden White, Arthur Danto, and Hans-Georg Gadamer, he examines such issues as the difference between historical representation and artistic expression, the status of metaphor in historical description, and the relation of postmodernism to historicism. Ankersmit's fluent grasp (...) of European thought and his ability to incorporate concepts from literary theory, art history, the philosophy of science, and political thought into his analyses assure that this collection will interest readers throughout the humanities.

The vocabulary of representation is better suited to an understanding of historiography than the vocabularies of description and interpretation. Since both art and historiography represent the world, they are closer to science than are criticism and the history of art because the interpretation of meaning is the specialty of the latter two fields. Historiography is less secure in its attempt to represent the world than art is; historiography is more artificial, more an expression of cultural codes than art itself. Historiography (...) is a suitable paradigm for studying certain philosophical problems, particularly epistemology, or codified representation. Representation always requires the presence of two sets of non-referential logical dummies; disturbing the symmetry between these logical dummies gives rise to the position of realism and idealism. Epistemology is strongly inclined to disturb this symmetry. The parallels between recent developments in art and those in historiography demonstrate how much historiography is part of the contemporary cultural world. The deficiencies of modern philosophy of history can largely be explained by its tendency to neglect the cultural significance of the writing of history. (shrink)

Arthur Danto has made important contributions to both aesthetics and philosophy of history. Furthermore, as I shall try to show in this essay, his aesthetics is of great relevance to his philosophy of history, while his philosophy of history is of no less interest for his aesthetics.By focusing on the notions of representation, identity, and the identity of indiscernibles we shall discover how fruitful this cooperation of aesthetics and philosophy of history may be. Crucial to all historical writing and, hence, (...) to all philosophy of history, is the notion of identity through time and change. How could the historian write the history of x if x cannot be said to remain the same in the course of its history? It will become clear that aesthetics will provide us with a satisfactory solution for the problem, for the aestheticist notion of representation will enable us to define the notion of identity that the historian needs.Nevertheless, a certain friction can be observed between Danto's aesthetics and his philosophy of history. At the end of this essay I hope to show that Danto's philosophy of history will be our best guide to dealing adequately with this friction. (shrink)
