On the other hand, believing everything uncritically is the road to disaster. The faculty of doubt is essential. But rational doubt always rests on faith and not vice versa. The relation between the two cannot be reversed. The critical principle must necessary destroy itself.
Rational criticism rests on beliefs which are, for the moment, held acritically.
But these beliefs are themselves liable to critical questioning. If the critical principle is exalted to the supreme place in the enterprise of knowing, then the possibility of knowing anything is destroyed. They are simply expressions of the will. The will to power is the real driving force of history. Newbigin affirms Nietzsche's view by stating that the twentieth century has learned this lesson.
