I want to know the answer to the following question:
What topic were Hayek's next two books going to cover?
All the background I'm provided with is that "After editing a book on John Stuart Mill's letters he planned to publish two books on the liberal order, The Constitution of Liberty and "The Creative Powers of a Free Civilization" (eventually the title for the second chapter of The Constitution of Liberty).". Is that enough to answer the question?
Answer: yes
