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

When I speak of the aspiration towards the beautiful, of the ideal as the ultimate aim of art, which grows from a yearning for that ideal, I am not for a moment suggesting that art should shun the 'dirt' of the world. On the contrary! the artistic image is always a metonym, where one thing is substituted for another, the smaller for the greater. To tell of what is living, the artist uses something dead; to speak of the infinite, he shows the finite. Substitution... the infinite cannot be made into matter, but it is possible to create an illusion of the infinite: the image.

Man has, since the Enlightenment, dealt with things he should have ignored.

Off course, life has no point. If it had, man would not be free. He'd become a slave to that point and his life would be governed by completely new criteria: the criteria of slavery. Like an animal, the point of whose life is that life itself, the continuation of the species.
An animal carries out his slavish activities because it can feel the point of its life instinctively. Therefore its sphere is restricted. Man, on the other hand claims to aspire to the absolute.
