In this discussion we are to get determinate concepts of law, the State, and property in general, not of the law, State, and property of a particular legal system or of a particular family of legal systems. The concepts of law, State, and property are therefore to be determined as concepts of general jurisprudence, not as concepts of any particular jurisprudence.
1. By the concepts of law, State, and property one may understand, first, the concepts of law, State, and property in the science of a particular legal system.
These concepts of law, State, and property contain all the characteristics that belong to the substance of a particular legal system. They embrace only the substance of this system. They may, therefore, be called concepts of the science of this system. For we may designate as the science of a particular legal system that part of jurisprudence which concerns itself exclusively with the norms of a particular legal system.
The concepts of law, State, and property in the science of a legal system are distinguished from the concepts of law, State, and property in the sciences of other legal systems by this characteristic,—that they are concepts of norms of this particular system. From this characteristic we may deduce all the characteristics that result from the special substance of this system of law in contrast to other such systems. The concepts of property in the present laws of the German empire, of France, and of England are distinguished by the fact that they are concepts of norms of these three different legal systems. Consequently they are as different as are the norms of the present imperial-German, French, and English law on the subject of property. The concepts of law, State, and property in different legal systems are to each other as species-concepts which are subordinate to one and the same generic concept.
2. Second, one may understand by the concepts of law, State, and property the concepts of law, State, and property in the science of a particular family of laws.
These concepts of law, State, and property contain all the characteristics that belong to the common substance of the different legal systems of this family. They embrace only the common substance of the different systems of this family. They may, therefore, be called concepts of the science of this family of laws. For we may designate as the science of a particular family of laws that part of jurisprudence which deals exclusively with the norms of a particular family of legal systems, so far as these are not already dealt with by the sciences of the particular legal systems of this family.
The concepts of law, State, and property in the science of a family of laws are distinguished from the concepts of law, State, and property in the sciences of the legal systems that form the family by lacking the characteristic of being concepts of norms of these systems, and consequently lacking also all the characteristics which may be deduced from this characteristic according to the special substance of one or another legal system. The concept of the State in the science of present European law is distinguished from the concepts of the State in the sciences of present German, Russian, and Belgian law by not being a concept of norms of any one of these systems, and consequently by lacking all the characteristics that result from the special substance of the constitutional norms in force in Germany, Russia, and Belgium. Its relation to the concepts of the State in the science of these systems is that of a generic concept to subordinate species-concepts.
The concepts of law, State, and property in the science of a family of laws are distinguished from the concepts of law, State, and property in the sciences of other such families by this characteristic,—that they are concepts of norms of this particular family. From this characteristic we may deduce all the characteristics that are peculiar to the common substance of the different legal systems of this family in contrast to the common substance of the different legal systems of other families. The concept of the State in the science of present European law and the concept of the State in the science of European law in the year 1000 are distinguished by the fact that the one is a concept of constitutional norms that are in force in Europe to-day, the other of such as were in force in Europe then; consequently they are different in the same way as what the constitutional norms in force in Europe to-day have in common is different from what was common to the constitutional norms in force in Europe then. These concepts are to each other as species-concepts which are subordinate to one and the same generic concept.
3. Third, one may understand by the concepts of law, State, and property the concepts of law, State, and property in general jurisprudence.
These concepts of law, State, and property contain all the characteristics that belong to the common substance of the most different systems and families of laws. They embrace only what the norms of the most different systems and families of laws have in common. They may, therefore, be called concepts of general jurisprudence. For that part of jurisprudence which treats of legal norms without limitation to any particular system or family of laws, so far as these norms are not already treated by the sciences of the particular systems and families, may be designated as general jurisprudence.
