X-ray vision

I often think that it would be nice if there were something that one could do in order to determine the deep-most truth of the matter about oneself. The true reading. I suppose that's what psychoanalysis is supposed to be, and also what skilled tarot readers value in their cards. But the former hangs on too many a priori assumptions to be substantively correct, it seems to me, and the latter requires a leap of faith. I wish you could just know. Like an x-ray or an MRI. Then at least you would know what you're dealing with.
