In brief: A surprising amount of craft. The Groundlines are not an edifying book about the state but a book about why a legal order holds and against what it must let itself be measured. Five of its insights are available to any lawyer in daily practice — without one’s having to become a Hegelian.
1. Historical explanation is not justification
The most important methodological sentence of the book stands in § 3 Remark. A provision can often be explained seamlessly from its genesis — and is not thereby right:
a legal determination can be shown to be perfectly grounded and consistent based on circumstances and existing legal institutions, and yet be inherently wrongful and irrational.
Groundlines, § 3 Remark
Hegel then turns the argument round, in a way that becomes dangerous for historical justification: if an institution was justified by the circumstances of its day, then it follows — since those circumstances no longer obtain — that it has lost its right. Whoever argues historically often argues against himself.
2. Law is a system, not a heap
For Hegel every legal figure — property, contract, punishment, marriage, administration, constitution — is a stage of one thought: freedom giving itself determinate being. That is not edification but a methodological claim with consequences: legal institutions can be grounded against one another, not merely listed side by side. Whoever wants to know why property comes before marriage gets an answer — and can dispute it.
3. Whoever makes the law inaccessible commits a wrong
The sentence from § 215 Remark belongs on the wall of every legislative drafting office:
To hang the laws up so high, as Dionysius the Tyrant did, that no citizen could read them — or else to bury them in the extensive apparatus of learned books, collections of divergent judgments and opinions, customs, and so on, and, moreover, in a foreign language, so that knowledge of the valid law is accessible only to those who devote themselves to it in a learned way — is one and the same injustice.
Groundlines, § 215 Remark
What is remarkable is not the demand for publicity but its ground: it follows from § 132 — the right of the subject to be bound only by what it could have known. Inaccessible law is not impractical; it has been deprived of validity.
4. Definitions are perilous in law
In § 2 Remark Hegel takes over a Roman warning — omnis definitio in iure civili periculosa — and gives it a ground not found in every textbook on method: a definition that abstracts from existing representations makes the contradiction in the legal order visible instead of resolving it. His example has not been superseded:
Thus, for example, no definition of man would be possible under Roman law, for the slave could not be subsumed under it; in his status, that very concept is violated.
Groundlines, § 2 Remark
The case refutes the definition, not the other way round. Anyone who has ever had to construe a statutory text against a legal definition knows the experience.
5. The last step of applying the law cannot be grounded — and that is all right
The paragraph perhaps most liberating for practice is § 214. Hegel sees that every law, at the point where it meets the individual case, passes into the quantitative — and there reason stops:
It cannot be rationally determined, nor decided by the application of a determinacy derived from the concept, whether, for an offence, a corporal punishment of forty strokes, or of forty less one, is just […]. And yet already one stroke too many, one taler or one groschen, one week, one day of imprisonment too many or too few, is an injustice.
Groundlines, § 214 Remark
His resolution is not resignation but an assignment of competence: here the only interest is that a decision be made at all. And he expressly foresees that the legislator leaves this determination to the judge and limits him only by a minimum and a maximum — the sentencing range, avant la lettre, together with the observation that its limits too are „round numbers“.
And what he has not to say to lawyers
No code of law. Hegel says so himself in § 3 Remark: one should not expect the systematic development to result in „a positive legal code — that is, one such as an actual state requires“. Philosophical right relates to positive right „rather as Institutes to Pandects“. He supplies the Institutes. The Pandects one must write oneself.
