ALLAN C. CARLSON
The notion that the only purpose of marriage is to have and rear children has a long history. Even today in many countries and religions, inability to conceive children or the lack of doing so is grounds for annulment or divorce. It is only in relatively modern times that marriage has been seen as having other virtues to which these are not universally agreed.
