These two opinions (although one, as has been said, is of no consequence whatever) seem to have two very grave arguments in support of them. The first is, that the Philosopher says that whatever appears true to the greatest number cannot be entirely false. The second is, the authority of the definition by an Emperor. And that one may the better see the power of the Truth, which conquers all other authority, I intend to argue with the one reason as with the other, to which it is a strong helper and powerful aid. And, firstly, one cannot understand Imperial authority until the roots of it are found. It is our intention to treat or discourse of them in an especial chapter. CHAPTER IV. The radical foundation of Imperial Majesty, according to the Truth, is the necessity of Human Civilization, which is ordained to one end, that is, to a Happy Life. Nothing is of itself sufficient to attain this without some external help, since man has need of many things which one person alone is unable to obtain. And therefore the Philosopher says that man is naturally a companionable animal. And as a man requires for his sufficient comfort the domestic companionship of a family, so a house requires for its sufficient comfort a neighbourhood; otherwise there would be many wants to endure which would be an obstacle to happiness. And since a neighbourhood cannot satisfy all requirements, there must for the satisfaction of men be the City. Again, the City requires for its Arts and Manufactures to have an environment, as also for its defence, and to have brotherly intercourse with the circumjacent or adjacent Cities, and thence the Kingdom.
