“It isn’t up to the painter to define the symbols. Otherwise it would be better if he wrote them out in so many words! The public who look at the picture must interpret the symbols as they understand them.” — Pablo Picasso.
There is a symbiotic relationship between artist and viewer with the viewer serving an instrumental role in the making of a work of art. Art made with no thought of its audience is, at best, selfish self-expression, and that is the kind of art a child could make. An artist has the fearful task of opening his work up to the interpretation of the public. They may get it wrong, they may understand it better than he does, regardless that interplay between creation and viewer is at the heart of art.
