In October of 1947, Mohandas Gandhi gave a piece of paper to his visiting grandson, Arun Gandhi, upon which was written the following list — a list he said contained "the seven blunders that human society commits, and that cause all the violence." The next day, Arun returned home to South Africa, never to see his grandfather again. Gandhi was assassinated three months later.
Note: The same list was originally published by Gandhi in his journal, Young India, in 1925. It was titled, "Seven Social Sins."
