–《墨子 – 魯問》
Peng Qing Shengzi said: “The past can be known, the future cannot.” Mozi said: Suppose your parents met with misfortune a hundred li away. And there was just the margin of a single day. If they could be reached they would live, if not they would die. Here are a strong wagon and an excellent horse, and also a bad horse and a square-wheeled cart. And you are allowed to choose. Which would you take? It was replied: The excellent horse and the strong wagon of course, to make for a more speedy journey. Mozi said: How then is the future not knowable?
