German philosophers used this word to describe their belief that each nation has its own unique spirit. German nationalists argued that the German people should tap into it and express their unique national identity. The Grimm brothers went looking for it among the German people. What was it?

Answer :

The appropriate response is volksgeist. It is a German loanword for a special "soul" had on the whole by each individuals or country. The thought is regularly ascribed to the philosopher Johann Gottfried Herder, however he never really utilized the word.

The correct answer is the word volksgeist. It literally means "spirit of the people," or "national character," that each nation possesses. This was something that was important to the German people and the word that is now used all over the world. Reichstag is incorrect as that word means "Parliament." Nationalism and humanism are obviously wrong answers here as well. which only leaves us with volksgeist.
