There has been a lot of discussion lately about the problem of evil, God’s existence, and God’s goodness. For Catholics at least, these issues must be understood in terms of the convertibility of the transcendentals, the privation view of evil, and the doctrine of analogy, all of which are so often notoriously misunderstood (probably because they are so often inadequately explained). However, I think that properly understood, these doctrines make a lot of sense and are eminently defensible. Here I largely draw from the work of analytical Thomists Peter Geach and Brian Davies, who, of course, have drawn from the work of the Angelic Doctor himself. I will phrase everything in as accessible a manner as I can, but I am indebted to the aforementioned authors for these ideas.Goodness and being are really the same. They differ only coneptually. The goodness of something consists in its being desirable. Hence Aristotle’s dictum that ‘good is what everything desires’. But desirability evidently follows upon perfection, for things always desire their perfection. And the perfection of a thing depends on the extent to which it has achieved actuality. So, something is obviously good inasmuch as it is a being . . . So, good clearly does not really differ from being, though the word ‘good’ expresses a notion of desirability not expressed by the word ‘being’. (S.T. Ia5.1)
First we’ll consider what we mean when we say that something is good. Consider a few propositions:
The house is red.
The cat is grey.
The house is small.
The cat is big.
When we say that one thing is red and another thing is grey, we know something intrinsic to each of the things we are talking about, even if we don’t know what the objects are. If I say “A is red” and “B is grey,” you know something particular about A and B. When we say one thing is small and another thing is big, however, we do not know something intrinsic to each of the things we are talking about unless we know what the objects are, since a small house is still bigger than a big cat. Simply knowing what is predicated of the object does not tell us anything about the object. We mean that the house is small for a house and the cat is big for a cat. Saying “A is small” and “B is big” does not tell me whether B is bigger than A, but saying “A is red” and “B is grey” does allow me to distinguish A and B with respect to color.
The same is true when we predicate “good” of an object. To say something is good does not tell us anything about the object if we do not know what the object is. A good house is said to be good for different reasons than a good cat is said to be good. A good house might be well-insulated, functional, and aesthetically appealing. A good cat might be healthy and agile. A thing is said to be good inasumuch as it fulfills its purpose: a house would be worse if it were poorly insulated or lacked a kitchen, and a cat would be worse if it got sick or broke its leg, but a house cannot get sick or break its leg, and it is certainly no detraction from a cat to say that it lacks a kitchen. Brian Davies notes, “To call something good, regardless of how we go on to justify our judgment, is to commend it for having what we are looking for in things of that kind.”
Conversely, to say that something is bad (or evil) is to say that it lacks what we are looking for in things of its kind. A cat is bad inasmuch as it lacks what it takes to be a cat (say, a healthy and functioning body). This is what it means to take a privation view of evil: badness occurs in things only as they lack what is proper to them. It is bad for a person to have cancer in the respect that it prevents the person from being what we expect a person to be (even though a tumor is a physical addition to a person’s body). There is nothing inherently bad about a hurricane (it is even good, on this view, for a hurricane to do what a hurricane tends to do), but it is an evil for a hurricane to destroy crops and lead to the starvation of a community. To quote Davies again, “On this account, ‘badness’ (or ‘evil’) is a word we use to signifiy a gap between what is actually there and what could be there (and should be there) but is not.”
This is a good starting point to think about the three doctrines I wanted to address.
