Suggested Discussion Questions:
1. Rabbi Joshua's first statement was understood in a context of loss. If a wife dies or he divorces he should remarry. This is similar to an earlier statement that a man should not live without a wife and and woman without a husband. Why do you think the tradition saw conjugal companionship as something to recommend at any age?
2. While the minimal duty was for two children, Rabbi Joshua encourages more since a man is like a farmer who plants many fields because he can't know which will thrive and survive and which not. Similarly, the future of children is always unknown. What does R. Joshua's addition to the mitzvah suggest about his understanding of the duty to reproduce?
