Achebe begins by defining an aesthetic as “those qualities of excellence which culture discerns from its works of art” and argues that our standards for this excellence are mutable — constantly changing, in a dynamic interaction with our social, cultural, and political needs:
Aesthetic cannot be fixed, immutable. It has to change as the occasion demands because in our understanding, art is made by man* for man, and, therefore, according to the needs of man, his qualities of excellence. What he looks for in art will also change… We are not simply receivers of aesthetics … we are makers of aesthetics.
Art, Achebe argues, arises out of its social context and must always be in dialogue with that social element:
Art has a social purpose [and] art belongs to the people. It’s not something that is hanging out there that has no connection with the needs of man. And art is unashamedly, unembarrassingly, if there is such a word, social. It is political; it is economic. The total life of man is reflected in his art.
