Whether God's Existence Can Be Proven XIV

The previous remarks explain why one has not shown that St. Anselm's Ontological Argument, or the five ways of St. Thomas Aquinas, or John Duns Scotus' apriori causal argument for proving God's existence are not proofs simply because there is disagreement about them or some people are not convinced by them. In order to show that these arguments are not proofs one must show that the arguments have an invalid form or that at least one of the premises is not true.

On the basis of these remarks one can conclude the fifth proposition (that "no human being up to the present moment has proven that God exists") is false if simply a certain set of logical conditions have been realized. If just one person some time in the past formulated a sound argument for God's existence, then the fifth proposition is false. It could be an argument which is not extant and was lost. This is why the fifth proposition is not proven even if one could show that all of the extant arguments for God's existence are in fact not proofs; for it is possible that someone in the past formulated a proof which was lost.

These remarks reveal the difficulty in proving that no one up to the present moment has proven that God exists, for this requires a knowledge of the past which is impossible for any human being nowadays to have.
