If it was a school only striving for genuine technical ability in painting that would be difficult enough but they are trying for more. The school is going for individual authenticity in imagination and in spiritual science.  Not an authenticity one might imagine as a dogmatic approach where the authentic painting style, the authentic approach to entering an imaginative process is dictated.  While the exercises are definitely structured the authenticity I am referring to is the authenticity of a start, an authenticity of questions and experiment. The conversation at the school is of our time and includes the questions concerning postmodern painting, art, culture, capitalism, technology, Marxism, materialism, society and knowledge.             
I remember it as an art school offering resistance and assistance and both of these well.
