 If the claim ‘what is best for a child is different in different cultures’ is a report of cultural difference—what each culture believes to be best for its children differs—then it is still consistent with the BIP having a single universal content. What is best for children is the same whatever the culture, and allowing for the variation in application of the same principle to different contexts. It is just that some cultures do not adhere to the BIP in this form. However things are clearly not that simple. It is one thing to acknowledge in principle that there must be a single BIP; it is quite another to find agreement on what that principle is. The discussions surrounding the formulation of international conventions of human rights have been notoriously beset by significant, and culturally based, differences of moral and political outlook. The United Nations Conventions on the Rights of the Child was no different (LeBlanc 1995).
