From an interview published in the February, 2005, issue of Locus
The power of being an author, the joy
of it for me, is that is one wasn't an author one would be a really boring person filled with peculiar bits of trivia, the sort you meet in a bar saying, "Did you know that...?" For an author, all of this "white knowledge",the kipple (*) in the back of your head, no longer is old keys and broken batteries, abandoned buttons, forgotten paper clips; it's actually useful! Most authors I know, whether or not they went through a standard education in their fields, tend to be autodidacts. And they tend to have that immense love of stuff
, of promiscuous and unbridled reading.
(*) Kipple: Kipple is a word coined by the sci-fi writer Philip K. Dick.
It refers to the sinister type of rubbish which simply builds up without any human intervention.
Example: Hey, look at the Kipple in this place.
Kipple breeds Kipple.
