[An approach to bacteriological taxonomy by application of Immanuel Kant's transcendental dialectics (author's transl)].

After having altered the name of International Committee for Bacteriological Nomenclature in International Committee on Systematic Bacteriology in 1970, the latter will also have to reflect upon the objects of taxonomy. An approach thereto is recognizable in the revision of the International Code of Nomenclature of Bacteria in 1975. Considerations are being made whether a classification of bacteria does justice to the laws of homogenicity, specification and continuity as laid down by Kant in his transcendental dialectic. Most important of all are definition and determination of the taxon species. As far as contents go the latter is not possible from the biological point of view but applicable to its range in application of the regulations of the code. Within the priorities of taxa the species adopts a preferential position because conceptions of applied bacteriology are contained therein. The variety of infra-subspecific subdivisions is taken into consideration; as far as the formae speciales are concerned considerations as made with regard to species apply.
