Moreover, the satellites are invisible to the naked eye, and therefore can exercise no influence over the earth, and therefore would be useless, and therefore do not exist.
Page 20 - All these facts were attempted to be accounted for by an incongruous system of " cycles and epicycles," as it is called. The advocates of this theory assumed that every planet revolves in a circle, and that the earth is the fixed centre around which the sun and the heavenly bodies move. They then conceived that a bar, or something equivalent, is connected at one end with the earth ; that at some part of this bar the sun is attached ; while between that and the earth, Venus is fastened — not to...
Page 206 - Threat'ning the world with famine, plague, and war ; To princes, death ; to kingdoms, many crosses ; To all estates, inevitable losses ; To herdsmen, rot ; to ploughmen, hapless seasons ; To sailors, storms ; to cities, civil treasons.
