Aristotle’s ethic was eudaimonistic, which was later developed by Thomas Aquinas. Evil is the negation of good and requires no ontological grounding and it is the case that everyone always acts according to what they believe is good. Thomas’ meta-ethic was that being and goodness are the same in reference but differ only in sense. He follows Aristotle in making the connection between goodness and desirability. “The formula of the good consists in this, that something is desirable, and so the Philosopher [Aristotle] says that the good is what all desire.” Although all things desire goodness, not all things capable of pursuing goodness and pleasure with understanding understand what really is good; it is possible for creatures with intellect and will to desire an apparent good as a real one. Thomas states that something is desirable in two ways, either because it is good or because it appears good. Of these, the first is what is good, for an apparent good does not move by itself but insofar as it has some appearance of good; but the good moves by itself. Desirability and pleasure is an essential aspect of goodness. The perfection of anything is goodness and perfection is attained in actuality, “As regards nature the good of anything is its actuality and perfection.”

The following argument is an abductive Thomistic cosmological argument from contingency, which I presented at my recent Ratio Christi debate.
- There are contingent constituents to the universe.
- Given the contingent constituents of the universe, the existence of the universe (U) is very, very unlikely under the hypothesis that these constituents are themselves uncaused or self-caused (~Cu): that is, P(U|~Cu & k) ≪ 1.
- Given the contingent constituents of the universe, the existence of the universe is not unlikely under the hypothesis of a first uncaused cause (Cu): that is, ~P(U|Cu & k) ≪ 1.
- Therefore, U strongly supports Cu over ~Cu.
The constituents of the universe include galaxies, planets, stars, cars, humans, leptons, bosons, and other particles. For the constituents of the universe to be uncaused that would mean it is metaphysically necessary. For something to be metaphysically necessary that means that it could not have failed to exist—it exists in every possible world.
For something to be self-caused it must be simultaneously antecedent to itself to produce itself as its own effect. But this contradictory. This would be akin to the ultimate bootstrapping trick.
