As to how they conceive their realization, the Anarchistic teachings divide into the _reformatory_, which conceive the transition from the negated to the affirmed condition as without breach of law (Godwin, Proudhon), and _revolutionary_, which conceive this transition as a breach of law. The revolutionary teachings, again, divide into _renitent_, which conceive the breach of law as without the use of force (Tucker, Tolstoi) and _insurgent_, which conceive it as attended by the use of force (Stirner, Bakunin, Kropotkin). II. _The place of the Anarchistic teachings in the total realm of our experience._ 1. There must be distinguished three lines of thought in the philosophy of law: that is, three fashions of judging law. The first is _jurisprudential dogmatism_. It judges whether a legal institution ought to exist or not, and it judges quite unconditionally, solely by what the institution consists of, without regard to its effect under this or that particular set of circumstances. It embraces, therefore, the doctrines of a _proper law_: that is, the schools that seek to determine what law--for instance, whether the legal institution of marriage--is under all circumstances to be approved or to be disapproved. Its best known form is "natural law." The weakness of jurisprudential dogmatism lies in its not taking account of the fact that our judgment of legal institutions must depend on their effects, and that one and the same legal institution has under different circumstances altogether different effects. The second line of thought is _jurisprudential skepticism_. In view of the weakness of jurisprudential dogmatism it foregoes judgment on whether a legal institution ought to exist or not, and pronounces judgment only on whether the tendency of evolution gives ground for expecting that a legal institution will persist or disappear, arise or remain non-existent. It embraces, therefore, the doctrines of the _evolution of law_: that is, the schools that undertake to inform us what sort of law is to be expected in future--for instance, whether the legal institution of marriage has a prospect of remaining in force among us. Its best-known forms are the historical school in the science of law, and Marxism. The weakness of jurisprudential skepticism consists in its not meeting our want of a scientific basis that shall enable us to recognize as correct or incorrect the incessantly-appearing judgments on the value of legal institutions, and to approve or disapprove the manifold propositions for changes in law.
