I want to know the answer to the following question:
According to Popper, what second layer does scientific inquiry have that pre-scientific inquiry does not?
All the background I'm provided with is that "Popper claimed to have recognised already in the 1934 version of his Logic of Discovery a fact later stressed by Kuhn, "that scientists necessarily develop their ideas within a definite theoretical framework", and to that extent to have anticipated Kuhn's central point about "normal science".". Is that enough to answer the question?
Answer: no
