Marx Engels Collected Works Volume 3. In general we can note that the conversion of the subject into the predicate, and of the predicate into the subject, the exchange of that which determines for that which is determined, is always the most immediate revolution. Not only on the revolutionary side. Likewise in regard to the constitution. The reactionaries as well.
Primogeniture is the law of the state.
The state demands the law of primogeniture. Owing to the fact, therefore, that Hegel makes the elements of the state idea the subject, and the old forms of existence of the state the predicate, whereas in historical reality the reverse is the case, the state idea being instead the predicate of those forms of existence, he expresses only the general character of the period, its political teleology. It is the same thing as with his philosophical-religious pantheism. By means of it all forms of unreason become forms of reason. But essentially here in religion reason is made the determining factor, while in the state the idea of the state is made the determining factor.
