The evil that is in the world almost always comes of ignorance, and good intentions may do as much harm as malevolence if they lack understanding. Albert Camus
Albert Camus (7 November 1913 – 4 January 1960) was a French philosopher, author, and journalist. His views contributed to the rise of the philosophy known as absurdism. He wrote in his essay The Rebel that his whole life was devoted to opposing the philosophy of nihilism while still delving deeply into individual freedom. He won the Nobel Prize in Literature at the age of 43 in 1957, the second youngest recipient in history.
