Harry Brighouse and Adam Swift Introduce an Intermediate Moral Principle

Harry Brighouse and Adam Swift introduce an intermediate moral principle about parenting to:

A) Show that income inequality is a serious moral problem because of the way it enables some parents to provide unfair advantages to their own children.
B) Justify the claim that parents are morally permitted to take any legal steps to benefit their children, even if that means putting other people's children at a competitive disadvantage.
C) Help resolve conflicts between the parental obligation to pursue good outcomes for one's children and the universal obligation to be fair to others.
D) Help parents understand how to apply the universal obligations of beneficence and nonmaleficence to their own children.
