I suppose they also had to do with my father, the Nazis, being skeptical of all systems, all manias. In the 70's, political positions were so clearly split in Germany - the country was so divided over the Baader-Meinhof group - and I was annoyed by both sides. In terms of what I expressed in the paintings, that seemed my only choice, not because I wanted to be ambiguous but because I myself don't know how to answer these difficult questions. That was what I was conveying.
