Moral truth, goodness, and beauty are defined as those that exist on their own, without the necessity of a contrary (inner) or contradictory (outer) opposite.
What is moral exists without a necessary opposite. God is moral because God exists without a necessary opposite. Whatever is of God is also moral. Whatever contradicts God or something of God is immoral. God is necessarily not self-contradictory.
Ethical truth, goodness, and beauty are defined as those that are non-arbitrary and balance contrary opposites. Every imbalance between contrary opposites is arbitrary because it could just as well be the opposite imbalance. Balance is its own contrary, so it is non-arbitrary.
Truth concerns logical consistency. Goodness concerns logical completeness. Beauty concerns the balance of logical consistency and logical completeness.
The difference between moral and ethical distinctions is the difference between contradictory opposites and contrary opposites. True and false are contradictories but in propositional logic they are represented by contraries. In predicate logic, true and false are related by inner and outer negations: false is the outer (contradictory) negation of true and vice versa; the other negations are inner (contrary) negations.
