Q1259Once Zhuangzi dreamed he was a butterfly. Waking, he no longer knew whether he was a man who had dreamed he was a butterfly, or a butterfly now dreaming it was a man.
The 'butterfly dream' from the Daoist classic named after Zhuangzi. It is one of philosophy's oldest doubts about how we know we are awake — and a gentle argument against being too sure of any single point of view.
