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 (26 July 1856 – 2 November 1950) was an Irish playwright and a co-founder of the London School of Economics. Although his first profitable writing was music and literary criticism, in which capacity he wrote many highly articulate pieces of journalism, his main talent was for drama, and he wrote more than 60 plays. He was also an essayist, novelist and short story writer. Nearly all his writings address prevailing social problems with a vein of comedy which makes their stark themes more palatable. Issues which engaged Shaw's attention included education, marriage, religion, government, health care, and class privilege.
