Book 2
1270b
For the lawgiver desiring to make the Spartiates as numerous as possible holds out inducements to the citizens to have as many children as possible: for they have a law releasing the man who has been father of three sons from military service, and exempting the father of four from all taxes. Yet it is clear that if a number of sons are born and the land is correspondingly divided there will inevitably come to be many poor men.
