As for mathematics, I gave it up for art when I realized there were no certainties in mathematics: you’re told that two parallels never meet, and then you learn that in a non-Euclidean geometry they can easily come together. I was disappointed and deeply disturbed, and I turned toward the certainties of feeling rather than those we are taught. If you accept inner certainties you become responsible for your own fate, you no longer depend on directives from the outside.
