I really liked Merton's intro. Especially his explanation of wu wei, which I though he did a good job on. Although I've never actually read anything by him before I've read about him and he sounds like he was a pretty cool guy.

I've not read much of Chuang Tzu's writing before, so I can't really say much about this translation in comparison to others. Don't know how I feel about the fact that it's an interpretation of translations. It's definitely easy to see Zen in much of the readings though. It has that same frustrating "I know I read something deep, but what?" feeling that zen koans love to leave me with. Also, I laughed at "Chuang Tzu's Funeral".
