The Traditional Theistic Proofs
The common charge of inconclusiveness brought against the traditional proofs of God’s existence is thus to a certain extent justified; for these proofs are, in their usual forms, isolated arguments, detached from any positive theology and attempting to demonstrate the existence of a God whose nature is very vaguely conceived.
This fact is sometimes expressed by saying that they are purely negative. It would be better to say that they are highly abstract, and that a full statement of any one of them would amount to the construction of a complete theological metaphysic.
No argument can be purely negative, for it is impossible to deny one principle except by asserting another, however little that other is explicitly developed.
