The theoreticians who lay down the strictest conditions for paternalistic interventions ultimately appeal to that which is generally considered worth aspiring to in a particular society. In the field of cultural politics, it is equally a matter of expanding knowledge of cultural products which are dubbed valuable by the society, the tradition. Ideas on this can change in the course of time, but are sufficiently stable to serve as starting-points for policy. To justify a cultural policy it is not necessary to be able to prove that certain cultural products are objectively beautiful or fine. One reason is that cultural policy has been primarily a facility policy. The authorities have generally confined themselves to creating a broad spectrum of cultural facilities and keeping entry prices down by subsidies. The underlying idea was that a supply affordable and accessible to all would, in itself, create a demand for culture.
