The problem with the human condition is we take what we sense as reality (which is a fixated belief). Those senses combined with reason and scientific method form science. If one is faith based it is all faith based. When I pick up an apple I see that it is something I perceive to be an apple. I taste it's sweetness. I feel it's texture. All these tell me that I am indeed eating an apple. But, we know that the senses are objective and they will differ from person to person. We also know that there are those among us who suffer from auditory and visual hallucinations. These people believe their senses even though according to us "normal" people these individuals are seperated from reality. The problem here is who knows if any of our senses are conducive to measuring and evaluating truth. So, while Nietzsche never acknowledged the inseperable nature of faith and science he did so indirectly and unpurposefully. So, I suppose a better way of wording my previous statement was to say what I derived from his writings.
