The sense of wonder certainly deprives the mind of those penultimate certainties that we had up till then taken for granted—and to that extent wonder is a form of disillusionment, though even that has its positive aspect, since it means being freed from an illusion; and it becomes clear that what we had taken for granted was not ultimately self-evident. But further than that, wonder signifies that the world is profounder, more all-embracing and mysterious than the logic of everyday reason had taught us to believe. The innermost meaning of wonder is fulfilled in a deepened sense of mystery. It does not end in doubt, but is the awakening of the knowledge that being, qua being, is mysterious and inconceivable, and that it is a mystery in the full sense of the word: neither a dead end, nor a contradiction nor even something impenetrable and dark. Rather, mystery means that a reality cannot be comprehended because its light is every-flowing, unfathomable, and inexhaustible.
