I mean sure sociology may not be classified as a humanities but archeology clearly is: “include the academic study of history” And sure maybe philosophers don’t need to travel but what do you do when you’re a historian and you need to consult historical records in another country? You are listing"the study of the performing art" how do you think people are studying these without going to the representations? And i may be biased because it’s what i am currently studying but how are we supposed to study geography without travelling???
