Abstract

Different approaches to the classification of a knowledge field include empiristic, rationalistic, historistic, and pragmatic methods. This paper demonstrates how these different methids have been applied to the classification of psychology. An etymological apporach is insufficient to define the subject matter of psychology, because other terms can be used to describe the same domain. To define the subject matter of psychology from the point of view of its formal establishment as a science and academic discipline (in Leipzig, 1879) it is also insufficient because this was done in specific historical circumstances, which narrowed the subject matter to physiologically-related issues. When defining the subject area of a scientific field it is necessary to consider how different ontological and epistemological views have made their influences. A subject area and the approaches by which this subject area has been studied cannot be separated from each other without tracing their mutual historical interactions. The classification of a subject field is theory-laden and thus cannot be neutral or ahistorical. If classification research can claim to have a method that is more general than the study of concrete developments in the single knowledge fields the key is to be found in the general epistemological theories. It is shown how basic epistemological assumptions have formed the different approaches to psychology during the 20th century. The progress in the understanding of basic philosophical questions is decisive both for the development of a knowledge field and as the point of departure of classification. The theoretical principles developed in this paper are applied in a brief analysis of some concrete classification systems, including the one used by PsycINFO / Psychologcal Abstracts. The role of classification in modern information retrieval is also briefly discussed
