First of all, it should be clear that politics has a great influence on art from the perspective of the development of the whole social history, but this influence is to think about the relationship between this influence in the superstructure field, not the relationship between decision and decision.

On the other hand, it should be clear that although politics and art are interactive, they are not parallel and have different positions in the superstructure.

The relationship between art and politics is clearly stated in the theory of historical materialism about economic base and superstructure: the economic base mainly acts on art through the intermediary of politics, and art also reacts on the economic base through the intermediary of politics.

2. The relationship between art and morality

Morality is a social life norm formed by human beings according to their social status and class relations. It can guide people's general speech and actions, and also influence the artist's ideology and its reflection on social life in his works of art. In class society, the morality of each ruling class always affects artists and their artistic creation to varying degrees, so that art can maintain its moral norms and thus its economic foundation. On the other hand, art can influence and transform people's moral concepts and play a role in changing customs.

There is another manifestation of the relationship between art and morality, that is, progressive art always tries to oppose the old morality and establish new morality, with the aim of destroying the old economic base and establishing a new economic base.

To sum up, the relationship between art and politics, morality and other "intermediate links" is the mutual influence and interaction in the superstructure field. On the one hand, they are not the relationship between decision and decision; On the other hand, the connection between art and economic foundation must go through "intermediate links", so the influence of politics and morality on art is inevitable.
