Often artists try not to talk or think about, what is their art for? Some people will admit, that art can’t even have a purpose. Art for art’s sake.
But I like things that have a practical use case. And so did Mark Rothko thinks about his work as well:
You’ve got sadness in you, I’ve got sadness in me – and my works of art are places where the two sadnesses can meet, and therefore both of us need to feel less sad.
– Mark Rothko
Art as place where you can go, if you feel sad. That is practical and shows that art can have purpose. We should have this in mind when we create or look at a work of art. This purpose can be totally individual and against the intent of the creator, but all art, if we like or do not like it, tells us something about and can be used by us.
