We have inhabited both the actual and the imaginary realms for a long time. But we don't live in either place the way our parents or ancestors did. Enchantment alters with age, and with the age. We know a dozen Arthurs now, all of them true. The Shire changed irrevocably even in Bilbo's lifetime. Don Quixote went riding out to Argentina and met Jorge Luis Borges there. Plus c'est la même chose, plus ça change.

There's a point, around the age of twenty, when you have to choose whether to be like everybody else the rest of your life, or to make a virtue of your peculiarities.

It is a real wilderness, and those who go there should not feel too safe.

It win be a device that will permit communication without any time interval between two points in space. The device will not transmit messages, of course; simultaneity is identity. But to our perceptions, that simultaneity will function as a transmission, a sending. So we will be able to use it to talk between worlds, without the long waiting for the message to go and the reply to return that electromagnetic impulses require. It is really a very simple matter. Like a kind of telephone.

Science fiction properly conceived, like all serious fiction, however funny, is a way of trying to describe what is in fact going on, what people actually do and feel, how people relate to everything else in this vast sack, this belly of the universe, this womb of things to be and tomb of things that were, this unending story.
