Abstract
Individual questions of the institutional reforms of the representative-democratic parliamentary system, such as issues of electoral law, party law, and parliamentary law, are frequently discussed. But all these reflections - and this is the principal thesis of this article - must eventually remain without success, if they do not address the preceding basic problem concerning the democratically indispensable conditions of the mental constitution of the active citizen, the „civis“. There, a key role, consciously experienced like a paradox, falls upon the renunciation of the claim to absolute truth of one’s own political convictions with regard to equally „relative-absolute“ claims for validity of others. On this base the psychological presuppositions of a modern pluralistic democracy are discussed, which thereupon are to be institutionalized: e. g. the capacity to compromise, the obligation of state neutrality in religious matters, the renunciation of hate speech, the rejection of „denial of reality“, and of allegedly „finalizing“ ideologies of history.
