There is only one law in art which carries objective character and comes from the very nature, conditional character and illusiveness of art! It is an indispensable condition of creation of an artistic image!
It is necessary to judge an artwork by intensity and importance of the image and force of its emotional influence!
Style, manner and technique don’t have any importance and they are equivalent! The good picture of a primitive artist can be much more valuable in the art sense than a ‘competent’ picture of a realist and on the contrary!
If there is an image, there is a work of art, if there isn’t, it’s no use crying for the moon! And it is not important which art means it has been reached by! Everyone to his ‘own’ taste!
