Athenian:  Let us place ourselves in thought at the moment when Lacedaemon and Argos and Messene and the rest of the Peloponnesus were all in complete subjection, Megillus, to your ancestors; for afterwards, as the legend informs us, they divided their army into three portions, and settled three cities, Argos, Messene, Lacedaemon.

Megillus:  True.

Athenian:  Temenus was the king of Argos, Cresphontes of Messene, Procles and Eurysthenes of Lacedaemon.

Megillus:  Certainly.

Athenian:  To these kings all the men of that day made oath that they would assist them, if any one subverted their kingdom.

Megillus:  True.

Athenian:  But can a kingship be destroyed, or was any other form of government ever destroyed, by any but the rulers themselves?  No indeed, by Zeus.  Have we already forgotten what was said a little while ago?

Megillus:  No.

Athenian:  And may we not now further confirm what was then mentioned?  For we have come upon facts which have brought us back again to the same principle; so that, in resuming the discussion, we shall not be enquiring about an empty theory, but about events which actually happened.  The case was as follows:—­Three royal heroes made oath to three cities which were under a kingly government, and the cities to the kings, that both rulers and subjects should govern and be governed according to the laws which were common to all of them:  the rulers promised that as time and the race went forward they would not make their rule more arbitrary; and the subjects said that, if the rulers observed these conditions, they would never subvert or permit others to subvert those kingdoms; the kings were to assist kings and peoples when injured, and the peoples were to assist peoples and kings in like manner.  Is not this the fact?

Megillus:  Yes.

Athenian:  And the three states to whom these laws were given, whether their kings or any others were the authors of them, had therefore the greatest security for the maintenance of their constitutions?

Megillus:  What security?

Athenian:  That the other two states were always to come to the rescue against a rebellious third.

Megillus:  True.

Athenian:  Many persons say that legislators ought to impose such laws as the mass of the people will be ready to receive; but this is just as if one were to command gymnastic masters or physicians to treat or cure their pupils or patients in an agreeable manner.

Megillus:  Exactly.

Athenian:  Whereas the physician may often be too happy if he can restore health, and make the body whole, without any very great infliction of pain.

Megillus:  Certainly.

Athenian:  There was also another advantage possessed by the men of that day, which greatly lightened the task of passing laws.
