What is art?

Andrei Tarkovsky:Before defining art, or any concept, we must answer a far broader question: What's the meaning of man's life on Earth? Maybe we are here to enhance ourselves spiritually. If our life tends to this spiritual enrichment, then art is a means to get there. This, of course, is in accordance with my definition of life. Art should help man in this process. Some say that art helps man to know the world like any other intellectual activity. I don't believe in this possibility of knowing, I am almost an Agnostic. Knowledge distracts us from our main purpose in life. The more we know, the less we know: getting deeper, our horizon becomes narrower. Art enriches man's own spiritual capabilities and he can then rise above himself to use what we call 'free will'.
