Classical republicanism is build on a few basic concepts, on of these concepts is vita activa . Vita activa is Latin for active life, but what is active life in a classical republican sense? First of all for classical republicans an active citizen is someone who is active in the public domain. Second an active works together with others to further the common good (res publica).
For centuries small city states with only a few thousand citizens, have been the ideal of classical republicans. Because of its limited size, a city-state would allow all its citizens to participate in politics. In larger political structures ( such as nation states or empires) its more difficult for individual citizens to participate in the political system. We see that in larger political structures a shift from self-governance to bureaucracy.
Since a return to small city states seems to unlikely in the modern world , classical republicans face the question whether we have a way to pursue the vita activa even in larger political structures. We believe that there is a way.
Voluntary associations are essentially miniature republics. Voluntary associations differ from other organizations in that VAs are run by their members: the members of the association appoint its board and can dismiss them. Even more importantly, in most voluntary associations activities are organized by their members. Voluntary associations are established to serve a certain purpose. It is this purpose that unites the members, as they usually join the VA because the support this cause. For these reasons voluntary associations are a good occasion for people to pursue the vita activa, and really active citizens can be active in multiple associations.
Citizens who are active in public life, are essential for the survival of a free and democratic society. Private citizens with experience in voluntary associations form a counter-force against career bureaucrats. Also publicly active citizens will be more interested in public affairs. Apathy is lethal for any free and democratic society.
If we want to promote active citizenship, we should stimulate people to join voluntary associations. But that is easily said. The difficult question is how we can stimulate people to join VAs? It is important that people should be familiar with voluntary associations from a very young age. It seems to be a hard task to seduce children to join a VA.
In order to stimulate children to join voluntary associations we propose the introduction of sport vouchers. A substantial portion of all voluntary associations are sport clubs. Most people who join a sport club do that in first place because they want to practice some sport (it’s hard to play football or hockey alone), while being a member of a VA is only of secondary importance. That is, however, no big deal, because once they are a member, they might become more enthusiast about being in a VA.
How will sport vouchers work? The idea is that all children will be able to join a sport club, regardless of their parent’s ability to pay membership fees. Instead the government will pay the fees for youth members. Our system has two important features: first children will be free to decide which sport they will do and at which club, and secondly the government will pay the fees to the sport associations directly rather than to the parents. The latter rule is meant to prevent parents from embezzling this money. Consequently signing up your child for a sport club will be free. Important to ad, is in our proposal the government will not only cover youth membership fees, but also the purchase of personal equipment (hockey sticks, shoes, clothing and so on).
It is essential that children are free to choose the sport they like most, because coercion to do a particular sport will have an adverse effect. How would children now what sport they will like most? One suggestion is to organize regular “sport fairs” at which children can try different sports.
Due to our commitment to secularism, we propose that only secular sport clubs (i.e. clubs which are not based on a certain religion) can participate in this program. Also clubs which discriminate against certain groups of people, will be excluded from the program.
 Other concepts are self-government, mixed government, the separation of the public and private domain.
 Space settlements could, however, cause a revival of classic city states.
