This chapter discusses marriage and reproductive choice issues. The chapter argues that feminists have seen marriage and reproduction as playing a crucial role in women's oppression and thus a central topic of justice. The chapter starts by defining and setting out the historical development of the philosophy of marriage, which shapes today's debates. The chapter argues that many of the ethical positions on marriage can be understood as divided on the question of whether marriage should be defined contractually by the spouses or by its institutional purpose. The debate further divides on whether that purpose necessarily includes procreation or may be limited to the marital love relationship. The chapter closes by discussing reproduction choice, specifically abortion and commercial surrogacy.
