The mode of election which has been described is a mean between monarchy and democracy, and such a mean should ever be observed in the state. For servants and masters cannot be friends, and, although equality makes friendship, we must remember that there are two sorts of equality. One of them is the rule of number and measure; but there is also a higher equality, which is the judgment of Zeus. Of this he grants but little to mortal men; yet that little is the source of the greatest good to cities and individuals. It is proportioned to the nature of each man; it gives more to the better and less to the inferior, and is the true political justice; to this we in our state desire to look, as every legislator should, not to the interests either of tyrants or mobs. But justice cannot always be strictly enforced, and then equity and mercy have to be substituted: and for a similar reason, when true justice will not be endured, we must have recourse to the rougher justice of the lot, which God must be entreated to guide. These are the principal means of preserving the state, but perpetual care will also be required. When a ship is sailing on the sea, vigilance must not be relaxed night or day; and the vessel of state is tossing in a political sea, and therefore watch must continually succeed watch, and rulers must join hands with rulers. A small body will best perform this duty, and therefore the greater part of the 360 senators may be permitted to go and manage their own affairs, but a twelfth portion must be set aside in each month for the administration of the state. Their business will be to receive information and answer embassies; also they must endeavour to prevent or heal internal disorders; and with this object they must have the control of all assemblies of the citizens.
