摘要：A division and classification are always some separation of elements of the larger whole. Any division of sciences and any classification of scientific disciplines and specialties are in some sense imperfect. On the one hand, the science – because of its basic mission – cannot be isolated from the practice. A division and classification of sciences are necessary to serve the best this practice. On the other hand, the division and classification of sciences are essential in order to have an efficiently administered sphere of science. Primary issue is promoting scientific resources within clearly defined areas of scientific realms, disciplines and specialties. A division of science into three large groups: life sciences, humanities and social sciences, exact sciences and engineering is in some sense a compromise – an attempt to reconcile the needs of practice and necessity for efficient science management
