In a decaying society, art, if it is truthful, must also reflect decay. And unless it wants to break faith with its social function, art must show the world as changeable. And help to change it.

This quote suggests that art should honestly reflect the state of the society it is in, even if the society is declining. Furthermore, the quote implies that art has an important social responsibility of portraying the world as capable of being changed and inspiring the viewers to work towards transforming the society for the better.
