It is obvious that art cannot teach anyone anything, since in four thousand years humanity has learnt nothing at all.

No one component of a film can have any meaning in isolation: it is the film that is the work of art. And we can only talk about its components rather arbitrarily, dividing it up artificially or the sake of theoretical discussion.

"One woman sent me on a letter written to her by her daughter, and the young girl's words are a remarkable statement about artistic creation as an infinitely versatile and subtle form of communication:
'...How many words does a person know?' she asks her mother. 'How many does he use in his everyday vocabulary? One hundred, two, three? We wrap our feelings up in words, try to express in words sorrow and joy and any sort of emotion, the very things that can't in fact be expressed. Romeo uttered beautiful words to Juliet, vivid, expressive words, but they surely didn't say even half of what made his heart feel as if it was ready to jump out of his chest, and stopped him breathing, and made Juliet forget everything except her love?
There's another kind of language, another form of communication: by means of feeling, and images. That is the contact that stops people being separated from each other, that brings down barriers. Will, feeling, emotion — these remove obstacles from between people who otherwise stand on opposite sides of a mirror, on opposite sides of a door.. The frames of the screen move out, and the world which used to be partitioned off comes into us, becomes something real... And this doesn't happen through little Audrey, it's Tarkovsky himself addressing the audience directly, as they sit on the other side of the screen. There's no death, there is immortality. Time is one and undivided, as it says in one of the poems. "At the table are great-grandfathers and grandchildren.." Actually Mum, I've taken the film entirely from an emotional angle, but I'm sure there could be a different way of looking at it. What about you? Do write and tell me please.."

In the case of someone who is spiritual receptive, it is possible to talk of an analogy between the impact made by a work of art and that of a purely religious experience. Arts acts above all on the soul shaping its spiritual structure.
