The mathematical model is unsuitable in as much as its existents are abstracta<br />
while God is real; but it is nonetheless useful for bringing out the crucial<br />
contrast between created <strong>and</strong> uncreated necessity. An entity that is neither<br />
generated out of a prior one nor can perish by natural means, which does not<br />
change <strong>and</strong> which may exist eternally, can yet be ‘contingent’ in the sense that<br />
its non-existence is possible. In Aquinas’s terms its essence is one thing, its<br />
existence another; <strong>and</strong> since the former does not entail the latter the fact of<br />
its existing is not self-explanatory. Put in regard to numbers, or angels, even if<br />
they exist praeter-naturally <strong>and</strong> eternally <strong>and</strong> cannot cease to exist other than<br />
by Divine annihilation they are not intrinsically existent. What the essence–<br />
existence argument set out earlier shows, I believe, is that the actuality of<br />
things whose essence is not existence is due to the ex nihilo creative causality<br />
of God. Evidently God’s being cannot be caused by something external, but<br />
nor can it be caused by something internal – the latter in part because if it<br />
were, then God would antecedently have been incompletely actual, but more<br />
pertinently this would involve a contradiction: attributing God’s existence to<br />
the efficacy of something pre-existent, namely God’s nature. We should not<br />
say, therefore, as Descartes, Spinoza <strong>and</strong> others have done, that God is ‘cause<br />
of itself ’ (Deus causa sui), for that requires action prior to existence; <strong>and</strong> nor<br />
should we say that in some other way God’s existence ‘follows from’ his<br />
essence. Rather God’s essence is existence. As reported in the Hebrew bible,<br />
when Moses asked God his name God said ‘I am who am’ (Exodus 3: 14);<br />
which is to say God is that whose nature is being. This is what it means to<br />
be uncreated necessary being: to be uncaused being itself. Of necessity there<br />
cannot be more than one such, <strong>and</strong> because it exhibits an essence/existence<br />
distinction the world cannot be necessary in this sense. Pace some contemporary<br />
formulations of divine necessity, God is not a necessary being existing<br />
in every possible world, but being itself antecedent to <strong>and</strong> transcendent of<br />
all created possibilia <strong>and</strong> necessaria.<br />
In light of this one might wonder whether, after all, the Anselmean ontological<br />
proof is not sound. For if God’s nature is to be, then an adequate<br />
notion of God’s essence must include reference to his existence; <strong>and</strong> so from<br />
the very concept of God it follows that God exists. The proper response is<br />
suggested by Aquinas’s oft misunderstood distinction between principles<br />
‘self-evident in themselves’ <strong>and</strong> principles ‘self-evident to us’. In brief, this<br />
distinguishes between propositions in which that which is predicated of the<br />
subject belongs to it as a matter of de re necessity, <strong>and</strong> propositions in which<br />
the predicate is included in the definition of the subject de dicto. For example,<br />
while it is not part of the nominal definition of ‘event’ that every event has a<br />
cause, it may yet be true as a matter of metaphysical necessity that every event<br />
is an effect. If so, then while this latter necessity is not evident to us merely in<br />
virtue of grasping the meaning of the term ‘event’, the proposition ‘every
