“Page 283: The late Saverio Scolari once said that it was impossible for the student of the historical or political sciences to foresee exactly what is going to happen in human societies in any future, near or remote, because some part in human events will always be due to what is called “chance,” and we shall never be able to calculate that factor in advance. He added, however, that we are much better able to foresee what is never going to happen, the negative reasoning having a secure foundation in what we know of human nature, which will never allow anything actually to occur that is fundamentally repugnant to it.”
