In reading a novel, any novel, we have to know perfectly well that the whole thing is nonsense, and then, while reading, believe every word of it. Finally, when we're done with it, we may find - if it's a good novel - that we're a bit different from what we were before we read it, that we have changed a little... But it's very hard to say just what we learned, how we were changed.
Ursula K. Le GuinI went to the springs while the sun was still up, and sitting on a rocky outcrop above the cave mouth I watched the light grow reddish across the misty pools, and listened to the troubled voice of the water. After a while I moved farther up the hill, where I could hear birds singing near and far in the silence of the trees. The presence of the trees was very strong...The big oaks stood so many, so massive in their other life, in their deep, rooted silence: the awe of them came on me, the religion.
