Style is besides the point. Nobody would pay attention if one always said the same thing, in the same words and the same tone of voice.
The different styles I have been using in my art must not be seen as an evolution, or as steps towards an unknown ideal of painting. Everything I have ever made was made for the present and with the hope that it would always remain in the present.
Style is often something which locks the painter into the same vision, the same technique, the same formula during years and years, sometimes during one's whole lifetime.
I who have been involved with all styles of painting can assure you that the only things that fluctuate are the waves of fashion which carry the snobs and speculators; the number of true connoisseurs remains more or less the same.
