" If we define the word Theos as that on which everything else depends but which itself depends on nothing else - a reasonable definition - then none of these scientific theories is theologically neutral. All of them rest on fundamental assumptions which can be questioned. But the questioning, if it is to be rational, has to rely on other fundamental assumptions which can in turn be questioned. It follows (and this is Polanyi's point) that there can be no knowing without personal commitment. We must believe in order to know. "
