No Vocabulaire technique et critique de la philosophie, de André Lalande, lê-se: 'quando se fala em reduzir um fato a certos elementos tem-se em conta seja uma limitação e um empobrecimento inaceitáveis, seja, pelo contrário, uma simplificação útil e legítima que conserva o essencial do fato em questão'. O modo de pensar reducionista, de que se ocupa este artigo, corresponde à primeira daquelas acepções e como tal é criticado com o auxílio de dois autores clássicos, em ordem não cronológica: Hegel (...) e Dante.

Philosophers’ traditional emphasis on theories, theoretical modeling, and explanation misguides research in philosophy of science. Articulating and applying core theories is part of scientific practice, but it is not the essence of scientific practice. Insofar as science has an essence, it is to systematically investigate and learn about what is not yet understood. This lecture analyzes genetics to articulate a broad-practice-centered approach to philosophy of science. It concludes by arguing that this approach can lead to richer, deeper, and more useful (...) philosophies of science, philosophies that can better inform science policy and the public’s understanding of science.

In Defense of Utilitarianism, C.L. Sheng provides a more intensive study of the Unified Utilitarian Theory , which he proposed in his previous work A New Approach to Utilitarianism . Sheng defends utilitarianism, particularly UUT, against the objections and attacks raised by nonutilitarians, showing it to be a viable ethical theory.

This article shows how there is a great kinship between Polanyi's thought and that of Bernard Haring, "the father of modern moral theology" in the Roman Catholic Church. Haring advocated an ethics of personal responsibility that calls for an epistemology such as Polanyi developed for history and social sciences in The Study of Man.

In this paper we try to answer the question whether diffusion is a possible mechanism to explain mesoderm induction in Amphibians. First the embryological data are discussed and a hypothesis for mesoderm formation is set forth. The blastula being essentially a hollow sphere, we assume that the induction mechanism in an embryo at the blastula stage can be simulated by diffusion-reaction processes on spherical surfaces. A model is constructed for the simple case when the source is held constant with respect (...) to time, the decay proportional to the concentration and the diffusion coefficient a constant, From simulation we find a (best) value for the decay constant to be 6 × 10–5/sec and for the diffusion constant to be 0.24 × 10– 6 cm2/sec. The relation between the parameters is derived from an analytic solution for the diffusion process on a spherical surface with a continuously producing point source and the concentration proportional to the decay. The form and regulative properties of the steady concentration gradient are discussed. (shrink)

Bespiegelingen over collectieve schuld en symbolische identiteit, waarmee Duitsers nog steeds worstelen. Uiteindelijk zijn ook de Duitse oorlogsmisdaden terug te brengen tot een menselijk tekort, een probleem van de menselijke psyche in het algemeen.
