All killing of beasts for food is done by bondmen, lest free citizens should learn cruelty.

Context

“If a town grows too large, some of the inhabitants are moved into another town. If all the towns are too large, a new town is built on waste land. Nothing is said as to what is to be done when all the waste land is used up. All killing of beasts for food is done by bondmen, lest free citizens should learn cruelty. There are hospitals for the sick, which are so excellent that people who are ill prefer them. Eating at home is permitted, but most people eat in common halls. Here the “vile service” is done by bondmen, but the cooking is done by women and the waiting by the older children.” source
