Abstract
A distinction is made between three concepts of science: science as a particular form of knowledge, as an institution, and as an idea. These concepts are linked to three aspects of philosophy of science: logic of science, sociology of science, and ethics of science. The discussion focusses on the problematic relation between logic of science and sociology of science . Further topics: The distinction between the 'research form' and the 'theory form' of science. While analyses in the philosophy of science are first of all oriented towards the 'theory form' of science , it is the 'research form' of science which will be of growing importance now. Different approaches in the philosophy of science lead to different models of rationality . It is argued that philosophy and sociology of science are the area in which science may regain its status as a planning subject
