Okay, here is mine and while not Zelazny, it is sci-fi. It's from Clifford D Simak's City.
"These are the stories that the Dogs tell when the fires burn high and the wind is from the north. Then each family circle gathers at the hearthstone and the pups sit silently and listen and when the story's done they ask many questions.
"'What is Man?' they'll ask.
"Or perhaps: 'What is a city?'
"Or: 'What is war?'"
