I want to know the answer to the following question:
According to Bastian, what did he believe all human societies shared?
All the background I'm provided with is that "According to Bastian, all human societies share a set of "elementary ideas" (Elementargedanken); different cultures, or different "folk ideas" (Völkergedanken), are local modifications of the elementary ideas.". Is that enough to answer the question?
Answer: yes
