God are nonsensical, so far from being identical with, or even lending any support
to, either of these familiar contentions, is actually incompatible with them. For if
the assertion that there is a god is nonsensical, then the atheist’s assertion that
there is no god is equally nonsensical, since it is only a significant proposition that
can be significantly contradicted. ( LTL 115)
For some years, believing philosophers were alarmed by verificationist
arguments against religious doctrines, and strove to defend their meaning-
fulness without making much effort to demonstrate their truth. Towards
the end of the twentieth century, however, some natural theologians
recovered confidence and were much less defensive in their attitudes.
Typical of this phase is Alvin Plantinga, first of Calvin College, Grand
Rapids, and later of Notre Dame University.
For instance, Plantinga has offered a sophisticated restatement of the
ontological argument. In a simplified version his revision goes like this. Let
us begin by defining the property of maximal excellence, a property that
includes omniscience, omnipotence, and moral perfection. Obviously God,
if he exists, has maximal excellence in the actual world. But maximal
excellence is not sufficient for Godhead: we need to consider worlds
other than this one.
Those who worship God do not think of him as a being that happens to be of
surpassing excellence in this world but who in some other worlds is powerless or
uninformed or of dubious moral character. We might make a distinction here
between greatness and excellence; we might say that the excellence ofabeinginagiven
worldWdependsonlyuponits...propertiesinW,whileitsgreatnessinWdepends
not merely upon its excellence in W, but also upon its excellence in other worlds. The
limiting degree of greatness, therefore, would be enjoyed in a given world W only by a
being who had maximal excellence in W and in every other possible world as well.3
Maximal greatness therefore is maximal excellence in every possible world,
and it is maximal greatness, not just maximal excellence, that is equivalent
to divinity or Godhead. Any thing that possesses maximal greatness must
exist in every possible world, because in a world in which it does not exist it
does not possess any properties. If it is possible for maximal greatness to be
instantiated, then it is instantiated in every world. If so, then it is instan-
tiated in our world, the actual world; that is to say, Godhead is instantiated
and God exists.
