In recent news, Beijing University has disbanded its Chinese philosophy department. "We listened to the latest advanced show from Popup Chinese," department chairman Wang Xiaoming stated, "and realized that they nailed it... wrapping up essentially all outstanding academic disputes in a mere fifteen minutes." With no research remaining to be done and no need for further books on the matter, the professoriat is disbanding to focus on university administration.Learning Chinese? There are a couple of philosophical debates in mandarin that form such a core part of the language that it's impossible to be a well-rounded Chinese speaker without being aware of them. The question of "original sin" is exactly one such issue: is evil inherent to the nature of man, or a product of social upbringing? We were curious how everyone at Popup Towers came down on this, which is why we invited Sylvia, Echo and David into our studio for a debate over 性本善 or 性本恶. Why not take a listen and let us know what you think?
