著名诗人威廉·布莱克用“通过一粒沙来看世界”来描述非凡的观察力。但有时认知方式也可以通过相反的渠道:通过世界来展现一粒沙。我自然不打算佯装因为我们看不见一粒沙,它就不存在了。但只要这粒沙融入“沙”这个整体中,我们就很难察觉到它在世界中的位置以及它与无数其他沙粒间的摩擦。用眼睛捕捉到那粒沙需要费很大的劲。 The famous poet William Blake uses “to see the world through a grain of sand” to describe extraordinary observation. But sometimes the way of knowing can also be through the opposite channel: Displaying a grain of sand through the world. I naturally do not intend to pretend that because we can not see a grain of sand, it does not exist. But as long as the sand is integrated into the whole “sand,” we find it hard to detect its place in the world and its friction with innumerable other grains of sand. It takes a lot of effort to catch the sand with your eyes.
