the unknown is the present moment. It cannot be known, only experienced. Once the unknown is known it has already been labelled and despatched to memory. Knowledge is not reality, just a documented corpse of experience past. The pursuit of reality (the unknowable) is the fear of the present. Fear is pursuing it, or, waiting for it to arrive. It is the fear that is mistaken for reality. Result; the living death that is the comfort of knowledge. (by the way, I dont know anything)
