Surely children are not born knowing right and wrong?
Children are not born knowing right and wrong arises out of the paternalist view of children, which mistakenly holds that children learn moral knowledge through coercion, and that no one would have any interest in improving their moral knowledge unless forced to do so. But actually, coercion impedes and impairs learning, including of moral knowledge, and the vast majority of people including children are trying to do the right thing and trying to improve, including morally, and no one has perfect moral knowledge.
