Abstract

In studies of the history of science two apparently diverging ‘ideal types’ can be distinguished. The internal analysis relies on methodology and on the philosophy of science and concentrates on the cognitive system and on the sequence of theories. The external analysis relies on sociology, the history of institutions, biographies, etc. and concentrates on the social system and on the interrelationship between science and society. Neither of the two approaches can claim to cover the whole truth and to give the only possible (causal) explanation, The cognitive content of scientific theories and the social process of bringing about and using them are by their very nature complementary.
