This paper deals with the following questions: What features of modern natural science are responsible for the fact that, of all forms of science, this form is technologically exploitable? The three notions: concept of nature, epistemic ideal, and experiment, suggest the most important components of my answer. I will argue, first, that only the peculiar interplay of the modern concept of nature with an epistemic ideal attuned to it can cast experiment in the specific, highly central role it plays in the pursuit of knowledge about nature. It will then become clear that the form of science in which experiment plays such a role will, necessarily, prove technologically exploitable.

Many texts on logic are written with a mathematical emphasis, and focus primarily on the development of a formal apparatus and associated techniques. In other, more philosophical texts, the topic is often presented as an indulgent collection of musings on issues for which technical solutions have long since been devised. What has been missing until now is an attempt to unite the motives underlying both approaches. Paul Hoyningen-Huene’s _Formal Logic_ seeks to find a balance between the necessity of formal considerations and the importance of full reflection and explanation about the seemingly arbitrary steps that occasionally confound even the most serious student of logic. Alex Levine’s artful translation conveys both the content and style of the German edition. Filled with examples, exercises, and a straightforward look at some of the most common problems in teaching the subject, this work is eminently suitable for the classroom.

The paper deals with the interrelations between the philosophy, sociology and historiography of science in Thomas Kuhn’s theory of scientific development. First, the historiography of science provides the basis for both the philosophy and sociology of science in the sense that the fundamental questions of both disciplines depend on the principles of the form of historiography employed. Second, the fusion of the sociology and philosophy of science, as advocated by Kuhn, is discussed. This fusion consists essentially in a replacement of methodological rules by cognitive values that influence the decisions of scientific communities. As a consequence, the question of the rationality of theory choice arises, both with respect to the actual decisions and to the possible justification of cognitive values and their change.

To begin, the so-called ‘selectivity of historical judgment’ is discussed. According to it, writing history requires a comparative criterion of historical relevance. This criterion contains philosophical elements. In Kuhn’s case, the criterion directs historical research and presentation away from Whiggish historiography by postulating a hermeneutic reading of historical sources. This postulate implies some sort of internalism, some sort of rationality of scientific development, and historical realism. To conclude, some consequences of Kuhn’s anti-Whiggism are discussed.Para empezar, se discute la llamada “selectividad del juicio histórico”. De acuerdo con ello, escribir historia requiere un criterio comparativo de relevancia histórica. Este criterio contiene elementos filosóficos. En el caso de Kuhn, el criterio aleja la investigación y la presentación histórica de la historiografía Whig al postular una lectura hermenéutica de las fuentes históricas. Este postulado implica alguna clase de internismo, de racionalidad del desarrollo científico y realismo histórico. Para concluir, se discuten algunas consecuencias de la postura anti-Whig de Kuhn.

The present volume aims at giving a discussion ot the problems ot reductionism in contemporary life sciences. It contains six papers which deals with reduction/reductionism in different fields ot biological research. Also, the holistic perspective, 1. e. the systems view, is discussed in some ot the papers. The message ot this discussion Is that - whereas reductionism is indeed an important strategy - the systems approach is needed. It is argued by some ot the authors that organisms are complex systems and not just heaps of molecules, 50 that the analytical method does not suffice. Recent developments in systems theory offer the possibility to install a more comprehensive view ot living systems what can be seen particularly in the field ot evolutionary biology. It is true that any organismic activity is molecular, this is to say that it is based on molecular mechanisms. But it is also true that the whole organism displays certain patterns ot behavior which are not just molecular. Any organism can be described as a system ot different levels ot organization different levels ot order and complexity - and it is important, theretore, to study all ot the organizational levels and to see their peculiarities. It should be obvious, however, that there is not one problem ot reduction/reductionism, but that there are many problems linked together and that these problems appear at different levels ot biological research and bio philosophical reflections.
