"I believe in the things that were done, and there are evidences of many things done on Mars. There are streets and houses, and there are books, I imagine, and big canals and clocks and places for stabling, if not horses, well, then some domestic animal, perhaps with twelve legs, who knows? Everywhere I look I see things that were used. They were touched and handled for centuries.— from "—And the Moon Be Still as Bright" in The Martian Chronicles, by Ray Bradbury.
"Ask me, then, if I believe in the spirit of the things as they were used, and I'll say yes. They're all here. All the things which had uses. All the mountains which had names. And we'll never be able to use them without feeling uncomfortable. And somehow the mountains will never sound right to us; we'll give them new names, but the old names are there, somewhere in time, and the mountains were shaped and seen under those names. The names we'll give to the canals and mountains and cities will fall like so much water on the back of a mallard. No matter how we touch Mars, we'll never touch it. And then we'll get mad at it, and you know what we'll do? We'll rip it up, rip the skin off, and change it to fit ourselves."
