   The topics discussed above hardly exhaust the philosophy of childhood.  Thus we have said nothing about, for example, philosophical literature on personhood as it bears on questions about the morality of abortion, or bioethical discussions about when it is appropriate for parents to consent to children’s participation in medical research or refuse medical treatment of their children. There has been increasing attention in recent years to questions about the appropriate limits of parental authority over children, about the source and extent of parents and the state’s responsibilities for children, and about the moral permissibility of parents devoting substantial resources to advancing the life prospects of their children. These and many other topics concerning children may be familiar to philosophers as they get discussed in other contexts. Discussing them under the rubric, ‘philosophy of childhood,’ as well in the other contexts, may help us see connections between them and other philosophical issues concerning children.
