But what does it mean to show us what the metaphysical traits of “being” really are, when, admittedly, nothing can be said about these traits? And are we not supposed to be done with metaphysical traits and with a “being” of which no one can say anything? It were better if Wittgenstein had included science as well as metaphysics when he said, “Wovon man nicht kann sprechen, daruber soll man schweigen.” Modern science has imposed silence upon God but in doing so, it was compelled to impose silence on itself. Modern science boldly asks for a criterion of meaning when one speaks to him of Christ. He assumes that he himself has a criterion, a principle of verification and of falsification, by which he can establish for himself a self-supporting island floating on a shoreless sea. But when he is asked to show his criterion as it functions in experience, every fact is indeterminate, lost in darkness; no one can identify a single fact, and all logic is like a sun that is always behind the clouds.
