Abstract

Modern society is characterized bycomplexity and change. Weber's theory of thesephenomena explained them with changes in basicreligious concepts. Conceptual changes areagain under investigation here, but the theoryis somewhat different. In this paper, it isassumed that law is a system that follows theAshby's systems theoretical law of requisitevariety. Society can respond to growth ofcomplexity in its environment by eitheradaptation or selective indifference. Theexample of the evolution of legal persons inGerman law is used here to show how law hasdeveloped contingent concepts as a cognitivebuffer between itself and the demandingenvironment of modern society. The legal systemcan balance adaptation and selectiveindifference by constructing and observing itsbasic concepts as contingent. The constructionof autonomy is shown to be a continuous processwhere law establishes an increased level ofautonomy.
