Abstract.  The article focuses on the problem of constitutional symbolism in functionally differentiated societies and its relevance to legal, political, and moral systems. The first part analyses differences between the three systems and their constitutional context. The second part concentrates on the moral symbolic function of modern constitutions and its temporal dimension. It shows that the “good/bad” moral code of constitutions draws on expressive symbolism and transforms it into evaluative symbolism and dogma of morality. The final part analyses the prospective character of modern constitution-making and its symbolic selectivity regarding the past. The paper concludes by emphasising the systemic pluralisation effect of constitution-making and the impossibility of constituting systems of “pure” law, morality, and politics.
