I am fascinated by modern painting. There is an anecdote about the father of all modern painters, Picasso. When somebody asked him about his twoheaded ugly women, he answered that it is art, because he can se the world this way. This way too, because he could see it in the conventional way too. And he then did draw a very classical act. I think that this anecdote is fictional because you can't to draw classically to be a modern painter. This wonderful, insightful and easy to understand book explains what is modern and what is esthetic in Piet Mondrian's abstract squares of colors and what differentiates them from the similarly fanciful work of a house painter.
