The fifth book commences in a sort of dithyramb with another and higher preamble about the honour due to the soul, whence are deduced the duties of a man to his parents and his friends, to the suppliant and stranger. He should be true and just, free from envy and excess of all sorts, forgiving to crimes which are not incurable and are partly involuntary; and he should have a true taste. The noblest life has the greatest pleasures and the fewest pains...Having finished the preamble, and touched on some other preliminary considerations, we proceed to the Laws, beginning with the constitution of the state. This is not the best or ideal state, having all things common, but only the second-best, in which the land and houses are to be distributed among 5040 citizens divided into four classes. There is to be no gold or silver among them, and they are to have moderate wealth, and to respect number and numerical order in all things. In the first part of the sixth book, Plato completes his sketch of the constitution by the appointment of officers. He explains the manner in which guardians of the law, generals, priests, wardens of town and country, ministers of education, and other magistrates are to be appointed; and also in what way courts of appeal are to be constituted, and omissions in the law to be supplied. Next--and at this point the Laws strictly speaking begin--there follow enactments respecting marriage and the procreation of children, respecting property in slaves as well as of other kinds, respecting houses, married life, common tables for men and women. The question of age in marriage suggests the consideration of a similar question about the time for holding offices, and for military service, which had been previously omitted. Resuming the order of the discussion, which was indicated in the previous book, from marriage and birth we proceed to education in the seventh book. Education is to begin at or rather before birth; to be continued for a time by mothers and nurses under the supervision of the state; finally, to comprehend music and gymnastics. Under music is included reading, writing, playing on the lyre, arithmetic, geometry, and a knowledge of astronomy sufficient to preserve the minds of the citizens from impiety in after-life. Gymnastics are to be practised chiefly with a view to their use in war. The discussion of education, which was lightly touched upon in Book ii, is here completed. The eighth book contains regulations for civil life, beginning with festivals, games, and contests, military exercises and the like. On such occasions Plato seems to see young men and maidens meeting together, and hence he is led into discussing the relations of the sexes, the evil consequences which arise out of the indulgence of the passions, and the remedies for them. Then he proceeds to speak of agriculture, of arts and trades, of buying and selling, and of foreign commerce.
