Starting in 1928 Jung held a seminar on dream interpretation. He was able to present what he had discovered in the Liber Novus using another person’s experiences. He also held a seminar on Nietzsche’s Thus Spoke Zarathustra where he presented that book as Nietzsche’s Liber Novus. {and we should look at that seminar}In the 1930’s Jung also began to study alchemy. In alchemy Jung discovered a way to give his research a wider historical and cultural connection beyond himself and his patients. The study of alchemy became his prime concern.
