Banal ideas cannot be rescued by beautiful execution.

In my view, this is […] the essence of the social task facing the museum: to relate the conceptual world of individual creativity, that is art, with that of collective creativity, in which in principle everyone participates and which thus enables everyone to feel himself to be its creator. This points to the emancipatory influence, which such an approach on the part of the museum can have in a cultural and political sense.
