References and Further Reading 1. Two Kinds of Natural Law Theory At the outset, it is important to distinguish two kinds of theory that go by the name of natural law. The first is a theory of morality that is roughly characterized by the following theses.
This claim is meant to express a basic metaphysical idea, namely, that if something exists, then it necessarily has some degree of goodness. We can divide existing things into two categories: If something is incorruptible, then by definition it cannot be made worse; that is, it cannot lose whatever goodness it may have.
Otherwise, it would not have any goodness it could lose. While this argument may be sufficient to show that corruptible things necessarily have goodness, Augustine uses it to identify a problem with the view that something can exist even if it has no goodness at all.
For if something has no goodness, then it cannot lose goodness and must therefore be incorruptible. And since incorruptibility is better than corruptibility, it looks as if something lacking goodness is better than its corruptible counterpart, which has goodness.
Clearly, this is incoherent. Yet this is precisely the implication of claiming that something with no goodness whatsoever can exist. According to Augustine, the only remedy for this problem is to deny the existence of things that have no goodness. If something exists, then it must necessarily have goodness.
Thus what Aquinas means to convey is that something is good insofar as it actual.
By contrast, evil has no actuality in its own right. For him, something is evil insofar as its existence is diminished or corrupted in some way. If something had no goodness whatsoever, it would lack all goods, even the good of existence itself.
Following Aristotle, Aquinas says that living things are composites of matter and substantial form. Aquinas goes on to argue that all substances seek their own perfection ST Ia 6.
That is, they all seek as their final end a fully realized state of existence or actuality. Yet a substance cannot achieve that final end without exercising the powers it has in virtue of its substantial form. As Scott MacDonald explains: In other words, a substance achieves its perfection through the proper exercise of its species-defining powers.
Aquinas considers a fairly straightforward objection to this view: But being cannot be more or less. In other words, goodness is a relative property. Some people are morally better than other people.
Some horses are more developed and better trained than other horses. Some organs are healthier and function better than other organs. In each case, the goodness things have will not be identical in terms of quantity. On the other hand, being understood in terms of being actual or existing is not varied in this way.
This crucial difference seems to prove that being and goodness cannot be the same. In addressing this worry, Aquinas concedes that there is a kind of existence, or being, that is all-or-nothing. Something has substantial being as long as it is actual or exists ST Ia 5.
That is, something is good insofar it exists or has being. On the other hand, members of the same species can enjoy different grades of maturity or completeness. For example, a healthy adult dog is more developed—that is, more actualized—than a puppy, whose fledgling state prevents it from participating in those activities characteristic of more mature dogs e.Modern opposition to natural law and natural rights.

D’Andrea, University of Cambridge. Thomas Aquinas is generally regarded as the West’s pre-eminent theorist of the natural law, critically inheriting the main traditions of natural law or quasi–natural law thinking in the ancient world (including the Platonic, and particularly Aristotelian and Stoic traditions) and bringing.
