I want to know the answer to the following question:
Who coined the term "thing-in-itself"?
All the background I'm provided with is that "and proliferation of hyphenated entities such as "thing-in-itself" (Immanuel Kant), "things-as-interacted-by-us" (Arthur Fine), "table-of-commonsense" and "table-of-physics" (Sir Arthur Eddington) which are "warning signs" for conceptual idealism according to Musgrave because they allegedly do not exist but only highlight the numerous ways in which people come to know the world.". Is that enough to answer the question?
Answer: yes
