Has anyone here heard about Zhuangzi (aka Chuang Tzu)? He is one of the founders of Taoism, and well known as a skeptical thinker. There is a three part book called Zhuangzi that uses monologues, anecdotes, metaphors, etc to make you think or prove a philosophical point, and covers a lot of the same topics that Buddha does. As in Buddhism, a secular would have to understand that some of the words are just a representation of the culture at the time and are not really important for the view he is trying to express. It's a good book! I recommend it. To those who have read it, what did you think?
