What is it that makes some people know beforehand the coming of floods, the coming of rain, the change in the weather, all the different changes in nature? No doubt there are signs beforehand, signs which become words for those who read them, and by those signs they understand the coming events of nature. For them, therefore, these are the language of nature; for others who do not know this language it is gibberish. What is it that makes those who understand astrology know about people, their past, their present and their future from the change of the planets and the stars? It is only that there are signs which indicate to them the past, present and future just as words do, and from these signs they learn of coming events. There are phrenologists who can see signs in the muscles of the head. Those who know physiognomy can see from the face of a person things that no one has told them, but which they read from his face. There are others who know a science such as palmistry, of a small part of man; even in that case the signs of the hands are for them just as loud words, just as is the form of the face.
