“Your world has changed so much in 20 years that you might as well have been transported to another. And you cannot detect this. In fact, you appear determined to see the appearances as having the same meanings and functions they held previous.

You need scouts. Not for frontiers, where you are certain to falter, but for the known — to alert you to those places and identities — those relationships and meanings — where your maps no longer apply. And you need them badly, and fast; because the places where your maps are wrong have become all the places. And you can’t tell.”
