Now, if rather everyone agrees that something is art, it is art. Everyone here means a professional art community, curators, critics, traders, other artists, people interested in art.
In this sense, the environment produces a kind of common understanding of what is art and what is not art, and this concept changes, evolves, and opens up to new trends and views. Once upon a time, sacred art was not seen as art in the sense that we understand it today. It was to serve God and religion. Today, dissected from its propaganda function, it is absolutely art.
In short, if something hangs in MoMa, it is an art, unless we are talking about a fire extinguisher – but here too, better be sure.
So if an artist tapes a banana to a gallery wall, is it art or not?
