What has had to be said concerning Cosmology applies still more to knowledge of a religious kind. Here we have to build up knowledge which has its origins in the experience of the spiritual world. To draw conclusions concerning such experience from the subject-matter of ordinary consciousness is impossible. In intellectual concepts the religious content cannot be opened out but only clarified. When one began to seek for proofs of God’s existence, the very search was a proof that one had already lost the living connection with the divine world. For this reason also no intellectualistic proof of God’s existence can be given in any satisfactory way.
