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.

Summary The typology of scientific research is of considerable importance for the development of the methodology of science. Apart from the typology accepted by UNESCO, the author introduces a new typology of scientific research, distinguishing the following types of research: diagnostic and generalizing, chronological and systematic, heuristic and justificatory, universalist and specialist, theoretical and practical, explanatory and descriptive and others.

On the basis of an analysis of different types of research, two main kinds may be distinguished: research with a general intention and research with an individual intention.
