His (Samuel Coleridge) dark senses were constantly in

His (Samuel Coleridge) dark senses were constantly in play, the frustration of them bringing illness. Weather and organic nature combined in a synaesthetic multi-media event, and this was the ground of all perception before it was divded up in daily living: the Primary Imagination giving way to the Secondary. Poetry was forever seeking a conscious return to this state, which existed all the time, whether he knew it or not.

The scientist does not study nature because it

The scientist does not study nature because it is useful to do so. He studies it because he takes pleasure in it, and he takes pleasure in it because it is beautiful. If nature were not beautiful it would not be worth knowing, and life would not be worth living. I am not speaking, of course, of the beauty which strikes the senses, of the beauty of qualities and appearances. I am far from despising this, but it has nothing to do with science. What I mean is that more intimate beauty which comes from the harmonious order of its parts, and which a pure intelligence can grasp.
