Politics is the process of shaping human coexistence. In democracies, we are used to the idea that the responsibility for this lies with political parties. While a political system provides a legal framework for private and public affairs, citizens are nonetheless required to contribute to making coexistence and communal life possible. It is certainly important to ask to which degree we must responsibly play our roles as members of a political community. If democracy presupposes a political culture, we need to understand what such a political culture is and how we can keep it alive.
