The present collection of seventeen papers, most of them already published in international philosophical journals, deals both with issues in the philosophy of logic, the philosophy of mathematics, the philosophy of language and epistemology. The first part contains critical assessments and somewhat deviant renderings of the work of two seminal philosophers, Frege and Husserl, as well as of the young Carnap and Kripke. The second part contains analyses of central issues in the philosophy of logic, the philosophy of mathematics and (...) semantics, including arguments on behalf of Platonism in the philosophy of mathematics, a defense of second-order logic, a new definition of analyticity, a sketch of a semantics for mathematical statements and a critique of Kripke s possible world semantics for modal logic.".

The vertebrate spleen has important functions in immunity and haematopoiesis, many of which have been well studied. In contrast, we know much less about the mechanisms governing its early embryonic development. However, as a result of work over the past decade‐mostly using knockout mice–‐significant progress has been made in unravelling the genetic processes governing the spleen's early development. Key genetic regulators, such as Tlx1 and Pbx1, have been identified, and we know some of the early transcriptional hierarchies that control the (...) early patterning and proliferation of the splenic primordium. In mouse and humans, asplenia can arise as a result of laterality defects, or the spleen can be absent with no other discernible abnormalities. Surprisingly, given the spleen's diverse functions, asplenic individuals suffer no major haematopoietic or immune defects apart from a susceptibility to infection with encapsulated bacteria. Recent evidence has shed light on a previously unknown role of the spleen in the development and maintenance of specific B cell populations that are involved in the initial response to infection caused by encapsulated bacteria. The lack of these populations in asplenic mice and humans may go some way to explaining this susceptibility. BioEssays 29: 166–177, 2007. © 2007 Wiley Periodicals, Inc. (shrink)

The hegemonic role of technology on the mental structures of contemporary society is analyzed in five pieces which comprise the first part of a collection of essays dedicated to the philosophical meditation on different topics.

Frege had not one but two different notions of sense, namely, that of ?Über Sinn und Bedeutung? and one implicit in a letter to Husserl of 1906 and elsewhere. This last one originates in Frege's notion of conceptual content. The distinction is used to clarify some obscurities in Frege's thought. In the last section a sort of ?explicans? of Frege's notion of conceptual content is introduced and applied to the semantic analysis of mathematics.

This article deals with public manifestations of Catholic religious officials, members of the hierarchy and recognized laity, in the context of the discussion of the National Education Plan - PNE. The focus of the analysis is a condemnation of what they call "gender ideology", present in the proposal document. Such manifestations are the reaffirmation of a conception of human beings as subject to the inexorable "laws of nature" that determine a social order marked by the rigid distinction of roles assigned (...) to women and men. The texts published at the time reveal changes and continuities in the Catholic discourse in its reference to "nature", understood in its biological materiality, as an unswerving fact of human reality, consisting in two sexes must unite under the "natural order". Gender theories are blamed by family disintegration, for providing support to new understandings of humanity, no longer based on bipolarity: men / women. A non extensive dossier of these texts formed the basis for the proposed analyzes. (shrink)

ANDES, Stephen J.C.; YOUNG, Julia. Local Church, Global Church: Catholic Activism in Latin America from Rerum Novarum to Vatican II. Washington, DC, The Catholic University of America Press, 201 O livro em questão insere-se em uma perspectiva analítica, tentando mostrar o jogo de adaptação e de continuidade ao trabalho no continente americano. Apesar do reconhecimento das mudanças notáveis introduzidas pelo Vaticano II, a tese é que, ao contrário do que é sugerido por uma certa literatura de historiografia e teologia latino-americana, (...) o ativismo católico dos anos 60 e 80 teve suas origens no período anterior, tendo, em parte, como ponto de partida a encíclica Rerum Novarum.

Quine’s criticism of the notion of analyticity applies, at best, to Carnap’s notion, not to those of Frege or Husserl. The failure of logicism is also the failure of Frege’s definition of analyticity, but it does not even touch Husserl’s views, which are based on logical form. However, some relatively concrete number-theoretic statements do not admit such a formalization salva veritate. A new definition of analyticity based not on syntactical but on semantical logical form is proposed and argued for.

There is a lot of misunderstanding and ignorance about Husserl’s philosophy among analytic philosophers. The present paper attempts to help correct that situation. It begins with some quotations of Husserl written around 1890, which clearly establish that he arrived at the distinction between sense and reference with independence from Frege. Then follows a brief survey of the most important themes of Husserl’s Logical Investigations, emphazising those that are of special interest to analytic philosophers. The paper concludes by mentioning other interesting (...) issues treated in later Husserlian writings, including his valuable conferences on ancient and modern logic from 1908-1909.Existen muchos malentendidos y mucha ignorancia acerca de la filosofía de Husserl entre los filósofos analíticos. El presente artículo intenta contribuir a corregir esa situacion. Él comienza con algunas citas de Husserl de aproximadamente 1890, que claramente establecen que Husserl obtuvo la distinción entre sentido y referente con independenica de Frege. Luego sigue un breve recuento de los más importantes temas de las Investigaciones Lógicas de Husserl, destacando aquéllos que son de particular interés para los filósofos analíticos. El artículo concluye haciendo référencia a otros temas tratados en escritos posteriores de Husserl, incluyendo sus valiosas conferencias acerca de lógica antigua y moderna de 1908-1909. (shrink)

El presente artículo traza una revisión de lo que actualmente se entiende por ciencia, arte y tecnología para poder mostrar cómo la ingeniería moderna y en particular la ingeniería civil, es un compendio de los tres componentes, siendo el medio necesario para la sostenibilidad ambiental y social hoy requeridas. La ingeniería se enfrenta a problemas y sigue un método, que no es exclusivamente científico. Necesita la aproximación al arte y el ingeniero debe contar con una formación humanística, de contenido humano (...) significativo, que lo proteja del excesivo tecnicismo ya que se mueve en el entorno de lo real, no del laboratorio. La investigación bibliográfica y documental de la historia de los distintos conceptos permite pensar la ingeniería desde la filosofía y tiene como objetivo proponer que la llamada perspectiva CATI3 (Ciencia-Arte-Tecnología-Ingeniería) sea el vehículo de aproximación al concepto de ingeniería e interpretar sus relaciones con la tecnología, el arte y la ciencia en su proyección a la sociedad.

The three funtions of vegetative life could serve to understand three gnoseological positions. Knowledge as if -als ob- it were nutrition, growth and generation, these three positions have been held by Kant, scholasticism and idealism respectively.

The quantum state of a d-dimensional system can be represented by a probability distribution over the d 2 outcomes of a Symmetric Informationally Complete Positive Operator Valued Measure (SIC-POVM), and then this probability distribution can be represented by a vector of $\mathbb {R}^{d^{2}-1}$ in a (d 2−1)-dimensional simplex, we will call this set of vectors $\mathcal{Q}$ . Other way of represent a d-dimensional system is by the corresponding Bloch vector also in $\mathbb {R}^{d^{2}-1}$ , we will call this set of (...) vectors $\mathcal{B}$ . In this paper it is proved that with the adequate scaling $\mathcal{B}=\mathcal{Q}$ . Also we indicate some features of the shape of $\mathcal{Q}$. (shrink)

Most areas of philosopher Edmund Husserl’s thought have been explored, but his views on logic, mathematics, and semantics have been largely ignored. These essays offer an alternative to discussions of the philosophy of contemporary mathematics. The book covers areas of disagreement between Husserl and Gottlob Frege, the father of analytical philosophy, and explores new perspectives seen in their work.

This paper offers an exposition of Husserl's mature philosophy of mathematics, expounded for the first time in Logische Untersuchungen and maintained without any essential change throughout the rest of his life. It is shown that Husserl's views on mathematics were strongly influenced by Riemann, and had clear affinities with the much later Bourbaki school.
