A debate broke out recently in the blogs about the ethics of having children. The occasion was the publication of a remarkably silly book arguing that reproduction is immoral. One blogger argued in response that people have an obligation to create new life as an expression of gratitude for the life they have been given. Another denied the existence of any such obligation but argued that having children is an important source of happiness for most people. In this fact he finds sufficient justification for having children, and for governments to help people afford to have them.
The discussion, while interesting, would have been unintelligible throughout most of human history. The absence of reliable means of contraception meant that having children was a less discrete decision than it is today. And while many people felt an obligation to bear children or wanted the emotional satisfactions they can bring, they also had an overwhelming practical reason for wanting them: They needed the help. They needed their offspring’s labor. They needed children, especially, to avoid hunger and privation in old age. The bargain was simple: Parents take care of their children until they are able-bodied, and in return get taken care of by their children when they no longer are.
