Abstraction is a mental process we use when trying to discern what is essential or relevant to a problem; it does not require a belief in abstract entities.

Equality of rights means that some people cannot simply impose obligations on others, for the moral agency and rights of those others would then be violated.

Guardians are necessary for children and abnormal adults, because they cannot make responsible choices for themselves.
