if they do not believe this statement, has it in their understanding that if their was a God, it

would be that thing which nothing greater can be conceived. The created cannot be greater than

the creator because the idea of the created was created by the creator and only by the creator. So

if one thinks about the possibility of a thing which nothing greater can be conceived and thinks it

possible, than that idea is in their understanding. Anselm says that it exists only in the

understanding or it exists there and in reality. That means that since everyone can conceive of the

idea of a thing which nothing greater can be conceived, than the only other group, is of people

who believe it to be true.
