Why do some believe that things must be proven (rationally) in order be known as true? I ask this question because I have come to a realization that every philosophy and worldview is founded on unproven ideas. It is kind of like geometry, I think. There are theorems which are proven truths. But these theorems are based on "unproven truths" called postulates. Every belief is based on unproven ideas, even empiricism.For this reason (including others), I accept neither materialism nor empiricism to be true. Immaterial things could be just like the "unproven truths" (Christianity holds some to be revealed) mentioned previously. Just because something isn't proven (rationally) does not mean it isn't true. I think that there has been an unfortunate underestimation of intuition and other things excluding the intellect in many materialist and empiricist circles. Intuition is vital to any philosophy. Things must just be known. So, if this is the case, why should the revealed truths of Christianity be thrown away? Why can't faith and reason work together? Why does the intellect and the intuition have to be separate in our search for Truth?
