Leo Tolstoy

During my stay in Paris, the sight of an execution revealed to me the instability of my superstitious belief in progress. When I saw the head part from the body and how they thumped separately into the box, I understood, not with my mind but with my whole being, that no theory of the reasonableness of our present progress could justify this deed; and that though everybody from the creation of the world had held it to be necessary, on whatever theory, I knew it to be unnecessary and bad; and therefore the arbiter of what is good and evil is not what people say and do, nor is it progress, but it is my heart and I.
