If, then, we pass from the general and abstract to the concrete, we have society as existing in history. The study of the facts which develop in concrete society Stammler consigns to a science which he calls _social (or political, or national) economics_. From such facts may still be abstracted the mere form, _i.e._, the collection of rules supplied by history by which they are governed; and this may be studied independently of the matter. Thus we get _jurisprudence_, or the technical science of law; which is always bound up inseparably with a given actual historical material, which it works up by scientific method, endeavouring to give it unity and coherence. Finally, amongst social studies are also included those investigations which aim at judging and determining whether a given social order is as it ought to be; and whether attempts to preserve or change it are objectively justified. This section may be called that of practical social problems. By such definitions and divisions Professor Stammler exhausts every possible form of social study. Thus we should have the following scheme: { General Study { Causal. { of Society. { Teleological. { { of the form { { (technical science { { of law). { { SOCIAL SCIENCE. { { { Study of Concrete { of the matter { Society. { (social economics). { { of the possible, { { (practical problems). We believe that this table correctly represents his views, although given in our own way, and in words somewhat different from those used by him. A new treatment of the social sciences, the work of serious and keen ability, such as Stammler seems to possess, cannot fail to receive the earnest attention of all students of a subject which is still so vague and controversial. Let us examine it then section by section.
