All true wisdom and all true faith are clearly expressed in the same moral law.
All the world is subject to one law, and all thinking beings have the same basic intellect. Therefore, all wise men share the same idea of perfection.
The more I dedicate my time to two things, the more they fill my life with ever-increasing pleasure. The first is the sky above me, and the second is the moral law within me.
Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets.
Moral law is so obvious and clear that even people who do not know the law have no excuse for violating it. They have only one recourse: to deny their intellect, which they do.
