Progress is a fact. Even so, faith in progress is a superstition. Science enables humans to satisfy their needs. It does nothing to change them. They are no different today from what they have always been. There is progress in knowledge, but not in ethics. This is the verdict both of science and history, and the view of every one of the world's religions. The growth of knowledge is real and - barring a worldwide catastrophe - it is now irreversible. Improvements in government and society are no less real, but they are temporary. Not only can they be lost, they are sure to be. History is not progress or decline, but recurring gain and loss. The advance of knowledge deludes us into thinking we are different from other animals, but our history shows that we are not.
John Gray (philosopher)
