If you have an apple and I have an apple and we exchange 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, 07/26/1856 - 11/02/1950 Erse dramatist, author and Nobel Prize Laureate
An invasion of armies can be resisted, but not an idea whose time has come.
