The transition of the family and civil society into the political state is thus this: that the spirit of those spheres, which is in itself the spirit of the state, now also relates to itself as such and is actual as their inner being. The transition is therefore derived not from the particular essence of the family etc. and the particular essence of the state, but from the general relation of necessity and freedom. It is exactly the same transition that is accomplished in the Logic from the sphere of essence into the sphere of the concept. The same transition is made in the philosophy of nature from inorganic nature into life. It is always the same categories that furnish the soul now for this sphere, now for that one. All that matters is to find, for the individual concrete determinations, the corresponding abstract ones.
