Abstract

The difficulties of the biological taxonomy development are argued to have been historically associated with two main problems: 1) the problem of searching for essential features which was unachievable within the framework of empiric taxonomy andcould be solved as a part of the mature theory; 2) the problem of developing of a model of the biological object the remedies of which were developed only in the XX century. The author argues that both problems are associated with the development of classificatory and system ontology and the relevant methodologies. The classificatory methodology from its inception is argued to have developed as a means of classification of biological diversity; furthermore it is claimed to have been assumed that the features representing classes possessed ontological nature that is they actually represent individual objects. The author concludes that taking into account the empiric nature of taxonomy that assumption turned to be false. In the modern taxonomy along with the classical approach a classificatory-system approach was developed. Fundamentally, it is a transition from the classical approach to the modern one which is held to imply the development of a system model of the study subject.
