Problem: However, for his part, Hayek found this term "singularly unattractive" and offered the term "Old Whig" (a phrase borrowed from Edmund Burke) instead. In his later life, he said, "I am becoming a Burkean Whig."

From whom did Hayek acquire the term he proposed as an alternative to libertarian?
The answer is the following: Edmund Burke
