We may illustrate our proposal by an example. The laws relating to marriage naturally come first, and therefore we may begin with them. The simple law would be as follows:--A man shall marry between the ages of thirty and thirty-five; if he do not, he shall be fined or deprived of certain privileges. The double law would add the reason why: Forasmuch as man desires immortality, which he attains by the procreation of children, no one should deprive himself of his share in this good. He who obeys the law is blameless, but he who disobeys must not be a gainer by his celibacy; and therefore he shall pay a yearly fine, and shall not be allowed to receive honour from the young. That is an example of what I call the double law, which may enable us to judge how far the addition of persuasion to threats is desirable. 'Lacedaemonians in general, Stranger, are in favour of brevity; in this case, however, I prefer length. But Cleinias is the real lawgiver, and he ought to be first consulted.' 'Thank you, Megillus.' Whether words are to be many or few, is a foolish question:--the best and not the shortest forms are always to be approved. And legislators have never thought of the advantages which they might gain by using persuasion as well as force, but trust to force only. And I have something else to say about the matter. Here have we been from early dawn until noon, discoursing about laws, and all that we have been saying is only the preamble of the laws which we are about to give. I tell you this, because I want you to observe that songs and strains have all of them preludes, but that laws, though called by the same name (nomoi), have never any prelude. Now I am disposed to give preludes to laws, dividing them into two parts--one containing the despotic command, which I described under the image of the slave doctor--the other the persuasive part, which I term the preamble. The legislator should give preludes or preambles to his laws. 'That shall be the way in my colony.' I am glad that you agree with me; this is a matter which it is important to remember. A preamble is not always necessary to a law: the lawgiver must determine when it is needed, as the musician determines when there is to be a prelude to a song. 'Most true: and now, having a preamble, let us recommence our discourse.' Enough has been said of Gods and parents, and we may proceed to consider what relates to the citizens--their souls, bodies, properties,--their occupations and amusements; and so arrive at the nature of education.
