George Bernard Shaw - Those who cannot change their minds cannot change anything. - quote.
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.
