Knowledge has entertained me and it has shaped me and it has failed me. Something in me still starves. In what is probably the most serious inquiry of my life, I have begun to look past reason, past the provable, in other directions. Now I think there is only one subject worth my attention and that is the precognition, the condition of my own spiritual state. I am not talking about having faith necessarily, although one hopes to. What I mean by spirituality is not theology, but attitude. Such interest nourishes me beyond the finest compendium of facts. In my mind now, in any comparison of demonstrated truths and unproven but vivid intuitions, the truth loses.
