“There is no common good that leads automatically to a single form of public communication... What is required is an equally differentiated rhetoric that can establish rules for speaking in different situations, for different audiences and for the multifarious objectives of governments. The structure of the public domain implies a few common basic rules for this differentiated rhetoric: communication should be based on truth and reliability, centered on the dignity of the citizen, on what ties citizens together and maintains the community as a prerequisite for individual life. For the communication designer in the public domain that means an understanding of the democratic and constitutional values that are to be symbolised.”
