Abstract

Summary One — Sided understanding of Aristotle led to the view that the principal aim of science is general knowledge. In modern times this view must be extended: also particular knowledge of concrete situations and objects has considerable validity for science. This kind of knowledge the author calls diagnostic. In all empirical sciences diagnostic studies form their necessary part. There are two poles in sciences concerning reality — the more and more developed general knowledge and the specialized knowledge about concrete situations, persons and their cultural and technical products. These two poles are joined in a new model of science which the author presents. Between these poles there exists a mutual independence: diagnostic studies constitute a firm basis for new generalisations and the existing knowledge of laws helps towards a better understanding of concrete situations and their diagnoses
