and stood on the edge of a precipice a thousand feet high, approaching it backwards until one-fifth of his feet overhung the chasm, when he beckoned Lieh Yü-k'ou to come on. But Yü-k'ou had fallen prostrate on the ground, with the sweat pouring down to his heels.
CAUSALITY.
The Penumbra said to the Umbra, “At one moment you move: at another you are at rest. At one moment you sit down: at another you get up. Why this instability of purpose?”
“I depend,” replied the Umbra, “upon something which causes me to do as I do; and that something depends upon something else which causes it to do as it does. My dependence is like that of a snake's scales or a cicada's wings (which do not move of their own accord). How can I tell why I do one thing or do not do another?”
DREAM AND REALITY.
Once upon a time I dreamt I was a butterfly, fluttering hither and thither, to all intents and purposes a butterfly. I was conscious only of following my fancies (as a butterfly), and was unconscious of my individuality as a man. Suddenly, I awaked; and there I lay, myself again. I do not know whether I was then dreaming I was a butterfly, or whether I am now a butterfly dreaming that it is a man. Between a man and a butterfly there is necessarily a barrier; and the transition is called Metempsychosis.
