"The poet, however, uses these two crude, primitive, archaic forms of thought (simile and metaphor) in the most uninhibited way, because his job is not to describe nature, but to show you a world completely absorbed and possessed by the human mind."

I have often had cause to feel that my hands are cleverer than my head. That is a crude way of characterizing the dialectics of experimentation. When it is going well, it is like a quiet conversation with Nature. One asks a question and gets an answer, then one asks the next question and gets the next answer. An experiment is a device to make Nature speak intelligibly. After that, one only has to listen.
