Philosophy of science and the sciences are related in an arbitrary and noncommital way. This has problematic consequences in terms of the disciplinary autonomy of the sciences, as shown in the example of the science of education. A new determination and definition of the relation between science and the philosophy of science demands, on the one hand, a greater willingness towards metatheoretical reflection and critique of the part of the individual sciences and, on the other hand, a reorientation within the (...) philosophy of science towards performing "service functions" with regard to the metatheoretical selfdefinitions of the sciences. This can be achieved by a constructivist, pragmatic and historical theory of knowledge and science. A central factor in a changed relationship between science and the philosophy of science is the scientific discipline's determination of its field of enquiry. This is seen to be an integral part of the process of establishing a discipline as a science. (shrink)
