To identify and conceptualize research problems in science, philosophers and often scientists rely on classical accounts of problems that focus on intellectual problems defined in relation to theories. Recently, philosophers have begun to study the structures and functions of research problems not defined in relation to theories. Furthermore, scientists have long pursued research problems often labeled as practical or applied. As yet, no account of problems specifies the description of both so-called intellectual problems and so-called applied problems. This article proposes (...) a new conceptual framework of problems that accounts both for intellectual aspects of problems and for their practical or applied aspects. I illustrate the account with an example of a recent research project from evolutionary biology, and I indicate further routes by that to develop the account, especially in connection to empirical studies of science.

Las propuestas de la teoría del derecho se pueden entender como un conjunto de soluciones a diversos problemas teórico-jurídicos. Esta manera de presentar la actividad resulta atractiva, pero no siempre es trasparente, porque no explicita qué se debe conocer para entender su carácter problemático. Por ello, en este trabajo analizo el concepto de problema a través de la noción de predicado relacional, y a partir de ahí extraigo criterios que permiten determinar qué debe ser considerado como tal y a partir (...) de qué consideraciones deben ser evaluadas sus soluciones. Luego, los resultados del análisis son utilizados para examinar un conocido problema normativo, mostrando así su utilidad analítica. En definitiva, se busca contribuir a un debate escasamente desarrollado en torno al concepto de problema. (shrink)

Scientific theories are analyzed in terms of the role that they play in science rather than in terms of their logical structure. It is maintained that theories: provide descriptions of the fundamental features of their domains; on the basis of 1, explain non-fundamental features of their domains; provide a guide for further research in their domains. Any set of propositions that carries out these functions with respect to some domain counts as a theory. This view of theories is developed and (...) defended, and provides the basis for reconsidering a number of issues in the philisophy of science. It is argued that theories need not be unrestrictedly universal with respect to space and time; that the distinction between observable and theoretical entities fails because observables do function as theoretical entities in scientific theories, that there is no genuine philosophical problem of reduction; that the notion of "levels" can be replaced by the notion of "domains"; and that theories are the basic unit of scientific knowledge.

The problem of induction has long been one of the central problems of empiricist epistemology. There are two main versions of this problem: to justify a strictly universal statement on the basis of a finite set of singular statements and to justify a new singular statement on the basis of some finite set of accepted singular statements. In both cases it is assumed that we have a set of singular statements with which to begin and that these singular statements are, (...) somehow, provided by observation; neither of these assumptions will be disputed in this paper. But there is another assumption without which there might well be no problem of induction:A. Any synthetic statement which is to be accepted as known must be justified on the basis of observation.It is only because philosophers assume A that they are faced with the problem of showing how we can infer from statements which have been justified by observation to others which have not. It is this assumption which will concern us here, for if there are no adequate grounds for accepting A, the problem of induction may not arise at all. (shrink)
