*Human beings have the capacity of reason which enables them to deduce right actions towards
the "common good"

moral authority and surrenders any right to obedience

apply to the whole community or the universe, they are governed by God. Eternal law is not

sun is really like, we only have an imperfect idea of its nature gained by observing its effects on
Earth.
