Before beginning I must say that speaking on art is extremely difficult, for there are many kinds of views upon it and nearly every opinion can be the right one. I personally must say that I have no opinion on art at all, or better that my opinion on art is always changing. As I want to be a painter myself, I am within the stream, within the current of art and therefore I cannot have the whole outsider's view on art. All that I can do therefore is to raise the problems that occupy me, but I am not able to solve them.
Therefore I think it would be best for me to quote the different opinions on art, the opinions of the artists themselves, the opinions of the outsiders of art, and then my own opinion.
In the public, that is to say in the non art-creating world, there are in general two views, two opinions on art that are especially and strikingly opposed.
1st: art must only give copies true to nature.
2nd: art must be expressive.
According to the first point of view art has only to give a true picture of the facts, a true picture of the reality. These people say art must be comprehensible and easy to understand. To their minds a picture is better, the more resemblance it has to the model, or to the painted object.
As for me, I must say that this opinion is entirely unfounded. Pictures that are made in such a way are nothing but photographs. Yes, it is true, that in former times painters made pictures true to nature and that they intended to give the pictures the utmost resemblance, but these pictures served only as photos and had no other purpose.
But now, after the invention of photography, it is senseless for artists to paint true to nature. As for the photo, I must say that it can never be a competitor of art.
I think, most of you will find it ridiculous to speak about such things at all, but it is a true and very regrettable fact that the majority of people think that way; art has only to have the aim to depict things in the most resembling way.
But there are still many people who admit they know nothing about art. It is the artist's task to disturb and awaken them.
Real art must be expressive. Real art must give things another sort of life. The aim of art is expression. The function of art is to infect others with the artist's world view. That is to say, while observing a picture of art you must feel something that neither nature nor a picture true to nature can give you. You must get the same feeling in observing a piece of art that the artist had, when he painted the picture. But at any rate you must be overwhelmed, you must get deeply impressed. For in a work of art there must be something supernatural that gives life to figures and things that seem to be dead.

I misread one sentece, thought it said 'Real art must gather songs of life'. There is a series on art in America I have been watching; https://youtu.be/HG1mgw6cIgA?si=uIijgCroE26RWLax Craft in America: NATURE episode (the first artist featured, whimsical willow structures, thought Hunder might have liked...)
