I want to know the answer to the following question:
During his time in Los Angeles, what was the topic of the seminars Hayek taught not related to his new book?
All the background I'm provided with is that "From 1962 until his retirement in 1968, he was a professor at the University of Freiburg, West Germany, where he began work on his next book, Law, Legislation and Liberty.". Is that enough to answer the question?
