De Monarchia (75 Books - XXXVI)
Dante begins this short book by telling his audience that he has an unpopular truth to share. “No one has attempted to elucidate it,” he says, “on account of its not leading directly to material gain,” but share it he must, because men are made to seek the truth, and he does not want to be accused by later generations of “hiding [his] talent.” So, he argues that the world ought to be ruled by a single absolute monarch, that the Roman Empire ruled the known world by right (which, presumably, is passed to its successor), and whose power is God-given, though not dependant on the Church.
