There was a man who was so disturbed by the sight of his own shadow and so displeased with his own footsteps that he determined to get rid of both. The method he hit upon was to run away from them.
So he got up and ran. But every time he put his foot down there was another step, while his shadow kept up with him without the slightest difficulty.
He attributed his failure to the fact that he was not running fast enough. So he ran faster and faster, without stopping until he finally dropped dead.
He failed to realize that if he merely stepped into the shade, his shadow would vanish, and if he sat down and stayed still, there would be no more footsteps.
(Zhuangzi, Chinese Taoist Philosopher, s. IV BCE [before common era)
