To live without faith is to die a hyppocrite. Man cannot live without faith, for we all must believe in something unprovable for the basis of our knowledge. All knowledge (real knowledge, not mistaken beliefs) is still, at root, faith for it is based on our presuppositions. To find your presupposition, simply ask yourself “Why?” to each fact. So if you say, “The sky is blue” you ask yourself “Why is the sky blue?” If the answer is “Because the atomosphere scatters light such that blue is the lightwave that is perceived” you ask yourself “Why is that the case?” At the point at which you finally must answer, “Because that’s the way it is” then you have found your presupposition, which is by nature unprovable and therefore taken by faith.
