This was the thought du jour in today's Social Studies (Globe and Mail).

"If you have an apple and I have an apple and we exchange these apples then you and I will still each have one apple. But if you have an idea and I have an idea and we exchange these ideas, then each of us will have two ideas."

- George Bernard Shaw

I can't decide whether this is deep or really not. What I mean is, I think this sounds deeper on first contact than it really is. It's really just saying that concrete, material things are zero-sum and non-material things are non-material. Wow. Matter has stable mass. Wow.
