² The usual reference here is to Dworkin, Taking Rights seriously, 1978. The fundamental difference between principles and rules had been highlighted earlier in a comparative methodological analysis by German jurist Josef Esser, Grundsatz und Norm in der richterlichen Fortbildung des Privatrechts, 1956 (Principle and Rule in Judicial Advancement of Private Law). For a modern account see Robert Alexy, Theorie der Grundrechte, 1985 ([Theory of Basic Rights).Google Scholar

⁷ The “Willenstheorie” (will-doctrine) claimed that a promisor is bound to his promise solely because he wants to be bound. The concurring “Erklärungstheorie“ (reliance-doctrine) held that the promisor is bound because the promissee relies on the promise. See Zimmermann (note 1), 584 seq. A thorough account of the disputing positions and their main proponents in the 19^th century is given by Sibylle Hofer, Freiheit ohne Grenzen? Privatrechtstheoretische Diskussionen im 19.

Although published in 1941 and prompted by the attempt to replace the BGB by a “Volksgesetzbuch“, Schmidt-Rimplers article does not reflect Nazi-ideology but rather presents an early example of economic analysis of contract law, cf.

²⁹ Id., 248 (concerning the problem of “Patientenverfügung“ - “living will”). The subject of Patientenverfügung will now be tackled by an expert commission headed by former Federal Judge Klaus Kutzer (see Frankfurter Allgemeine Zeitung, Tuesday Sept. 9, 2003). Its task will be to develop a legal framework for determining the validity of a “living will”. Until now, no special statutory law with regard to that issue exits in Germany.Google Scholar
