Arguing for Deontology

It may seem that if we see deontology as morally foundational, then there is no way to argue for it. When we get to the most fundamental belief, that is the point where there can be no further argument.

Not so. Even when there is nothing more foundational than the ultimate foundation, moral science is about observing what got built on the foundation, and that observation can be an argument of sorts.
