“In the social equation, the value of a single life is nil; in the cosmic equation, it is infinite... Not only communism, but any political movement which implicitly relies on purely utilitarian ethics, must become a victim to the same fatal error. It is a fallacy as naïve as a mathematical teaser, and yet its consequences lead straight to Goya's Disasters, to the reign of the guillotine, the torture chambers of the Inquisition, or the cellars of the Lubyanka” — British-Hungarian philosopher and ex-communist Arthur Koestler, author of the anti-totalitarian novel, Darkness at Noon. This quote is from his 1954 autobiography, The Invisible Writing.
