The third line of thought is _jurisprudential criticism_. In view of the weakness of jurisprudential dogmatism it foregoes passing judgment, without regard to the particular circumstances under which a legal institution operates, on whether that institution ought to exist or not; but yet in view of the weakness of jurisprudential skepticism it does not forego answering the question whether a legal institution ought to exist or not. It therefore sets up a supreme governing principle by which legal institutions are to be judged with regard to the particular circumstances under which they operate, the point being whether, under the particular circumstances under which a legal institution operates, it fulfils that supreme governing principle as well as is possible under these circumstances, or at least better than any other legal institution. It embraces, therefore, the doctrines of _the propriety of law_: that is, the schools that set up fundamental principles by which it is to be determined what law--for instance, whether the legal institution of marriage--ought under any particular circumstances to exist or not to exist. 2. With respect to the State these three lines of thought in the philosophy of law may arrive at different judgments, each one from its standpoint. First, to the _affirmation of the State_. So far as the schools of jurisprudential dogmatism affirm the State, they approve of it unconditionally, and so for our future as well as elsewhere, without any regard to its effects under this or that particular set of circumstances. Among the numerous affirmative doctrines of the State in the sense of jurisprudential dogmatism, the teachings of Hobbes, Hegel, and Jhering may perhaps be selected for emphasis as belonging to different sections of history. So far as the doctrines of jurisprudential skepticism affirm the State, they foresee, looking to the course evolution is taking, that in our future the State will continue to exist. The most notable representatives of jurisprudential skepticism, such as Puchta and Merkel, have offered no teaching regarding the State; but affirmative doctrines of the State in the sense of jurisprudential skepticism may be found, for instance, in Montaigne and Bernstein. Finally, so far as the doctrines of jurisprudential criticism affirm the State, they commend it for our future in consideration of the particular circumstances that at present prevail in our case. Jurisprudential criticism has thus far been most clearly set forth by Stammler, who, however, has offered no teaching with regard to the State; but, for instance, Spencer's teaching may rank as an affirmative doctrine of the State in the sense of jurisprudential criticism. Second, the three lines of thought in the philosophy of law may arrive at the _negation of the State_, each one from its standpoint.
