The original lecture was much longer and included some material on Mohism, which I will be recording for the student - but might also upload here, if it seems of interest on reflection (and if any listeners request to hear it).
The Dream of the Butterfly is a famous story (almost an anecdote, it's so short) told by Zhuangzi or Chuang Tzu in the book named after him. The philosopher dreams that he is a butterfly, which leads to musing about the nature of reality. For something so short, it has a lot of philosophical and metaphysical implications - some of which are explored in this podcast. Others will have found far more depth within the Dream than is presented here.
