"Give a man a fire and he's warm for the day, but set fire to him and he's warm for the rest of his life."
"The trouble with having an open mind, of course, is that people will insist on coming along and trying to put things in it."
"Some humans would do anything to see if it was possible to do it. If you put a large switch in some cave somewhere, with a sign on it saying 'End-of-the-World Switch. PLEASE DO NOT TOUCH', the paint wouldn't even have time to dry."
