Divine Attributes

What is God Like?

The Traditional List

There is a broad … consensus that the main divine attributes are:

… perfect being theism, or the ‘maximal greatness’ tradition, regards God as the uniquely perfect being or the maximally great being, and the attributes then specify what characteristics count as perfections, or which aspects of God are maximally great. (Everitt 2010: 78)

Classifying the list (Oppy and Scott 2010: 236–37)

Base qualities
Those that both God and people too can have: good, wise, powerful, free, …
O-qualities
The modified base qualities may be treated as a class of qualities themselves: omnipotence, omniscience, etc. (These will largely be our focus.)
Metaphysical qualities
Those that God can have but his creation cannot: simplicity, immutability, eternity, impassibility, necessity.
Originative qualities
Those characterising God’s relation to his creation: creatorship, but God is a source of goodness or morality or truth.

The Paradox of the Stone

The Paradox Formalised (After Savage (1967: 76))

(S1)
Let \(x\) be arbitrary. Either \(x\) can make it true that there is a stone which \(x\) that cannot lift, or not.
(S2)
If \(x\) can make it true that there is a stone which \(x\) cannot lift, then there is a possible proposition which \(x\) cannot make true (namely, that \(x\) lift the stone in question).
(S3)
If \(x\) cannot make it true that there is a stone which \(x\) cannot lift, then there is a possible proposition which \(x\) cannot make true (namely, that \(x\) create a stone meeting that description).
(S4)
Hence, there is a possible proposition which \(x\) cannot make true. (S1, S2, S3, constructive dilemma)
(S5)
If \(x\) is an omnipotent being, then \(x\) can make true any possibly true proposition. (Definition O2)
(S6)
\(x\) is not omnipotent. (S4, S5, modus tollens)
(SC)
But \(x\) was arbitrary; so no being is omnipotent. (S1–S6, universal introduction)

The Number of Omnipotent Agents

How Many Omnipotent Agents?

If a plurality of coexistent omnipotent agents were even possible, then possibly, at a time, \(t\), some omnipotent agent, \(x\), while retaining its omnipotence, endeavors to move a feather, and at \(t\), another omnipotent agent, \(y\), while retaining its omnipotence, endeavors to keep that feather motionless. Intuitively, in this case, neither \(x\) nor \(y\) would affect the feather as to its motion or rest. Thus, in this case, at \(t\), \(x\) would be powerless to move the feather, and at \(t\), \(y\) would be powerless to keep the feather motionless! But it is absurd to suppose that an omnipotent agent could lack the power to move a feather or the power to keep it motionless. Therefore, neither \(x\) nor \(y\) is omnipotent. This line of reasoning appears to reduce the notion of a plurality of coexistent omnipotent agents to absurdity. If such a reductio ad absurdum is sound, then a plurality of coexistent omnipotent agents is impossible. (Hoffman and Rosenkrantz 2017: §1)

The Dominance Dilemma

Dominating Beings

The Argument From Dominance (Oppy 2007: §IV)

(D1)
If our God is essentially good, then he is dominated by a possible deity who is ‘otherwise identical to ours at all times except for the fact that the being in question is not essentially perfectly good (but is rather essentially morally indifferent)’ (Oppy 2007: 81).
(D2)
If our God is omnipotent, he is only contingently good. (logic D, D1)
(D3)

If God is only contingently good, then

we have adopted a religiously unappealing conception of the creator of the world. … In view of the horrendous evils of this world, why should we suppose that the creator is perfectly good if we have already acknowledged that, at best, the creator is merely contingently perfectly good? (Oppy 2007: 82)

(D4)
If God is omnipotent, he is not the God of scripture. (D2, D3)
(D5)
The God of scripture is almighty.
(DC)
So either there is no God of scripture, or ‘almighty’ isn’t omnipotence. (D4, D5)
