If we take the case of a single man, we shall see the same rule manifested in him: all his powers are ordered to gain happiness; but his understanding is what regulates and governs all the others; and otherwise he would never attain to happiness. Again, take a single household: its end is to fit the members thereof to live well; but there must be one to regulate and rule it, who is called the father of the family, or, it may be, one who holds his office. As the Philosopher says: "Every house is ruled by the oldest."[159] And, as Homer says, it is his duty to make rules and laws for the rest. Hence the proverbial curse: "Mayst thou have an equal at home."[160] Take a single village: its end is suitable assistance as regards persons and goods, but one in it must be the ruler of the rest, either set over them by another, or with their consent, the head man amongst them. If it be not so, not only do its inhabitants fail of this mutual assistance, but the whole neighbourhood is sometimes wholly ruined by the ambition of many, who each of them wish to rule. If, again, we take a single city: its end is to secure a good and sufficient life to the citizens; but one man must be ruler in imperfect[161] as well as in good forms of the state. If it is otherwise, not only is the end of civil life lost, but the city too ceases to be what it was. Lastly, if we take any one kingdom, of which the end is the same as that of a city, only with greater security for its tranquillity, there must be one king to rule and govern. For if this is not so, not only do his subjects miss their end, but the kingdom itself falls to destruction, according to that word of the infallible truth: "Every kingdom divided against itself shall be brought to desolation." If then this holds good in these cases, and in each individual thing which is ordered to one certain end, what we have laid down is true. [Footnote 159: _Ibid._ i. 2, 6, quoting Hom. _Od._ ix. 114.--(W.)] [Footnote 160: Ficinus translates: "Uno proverbio che quasi bestemmiando dice, _Abbi pari in casa_."] [Footnote 161: "_Obliqua_" = [Greek: parekbaseis]. _V._ Arist. _Eth._ viii. 10; _Pol._ iii. 7.--(W.)] Now it is plain that the whole human race is ordered to gain some end, as has been before shown. There must, therefore, be one to guide and govern, and the proper title for this office is Monarch or Emperor. And so it is plain that Monarchy or the Empire is necessary for the welfare of the world.
