Hokkien dialects are typically written using Chinese characters (, Han-ji). However, the written script was and remains adapted to the literary form, which is based on classical Chinese, not the vernacular and spoken form. Furthermore, the character inventory used for Mandarin (standard written Chinese) does not correspond to Hokkien words, and there are a large number of informal characters (, the-ji or thoe-ji; 'substitute characters') which are unique to Hokkien (as is the case with Cantonese). For instance, about 20 to 25% of Taiwanese morphemes lack an appropriate or standard Chinese character.
What is written Cantonese based on?
A: unanswerable

In 1860, Adolf Bastian (18261905) argued for "the psychic unity of mankind". He proposed that a scientific comparison of all human societies would reveal that distinct worldviews consisted of the same basic elements. According to Bastian, all human societies share a set of "elementary ideas" (Elementargedanken); different cultures, or different "folk ideas" (Volkergedanken), are local modifications of the elementary ideas. This view paved the way for the modern understanding of culture. Franz Boas (18581942) was trained in this tradition, and he brought it with him when he left Germany for the United States.
What was the name of the person argued for "The psychic unity of mankind"?
