Yesterday's train of thought has taken an alarming direction. I let myself surrender to feeling, and as a result I saw something terrifying. But remember this is being enacted on a theatre stage: a metaphysical drama, distanced from ordinary life by the device of Humean irony. And there is a point.
There are two promising leads that emerge from my experiment. The first is the thought that in a way I am shadowing the inquiry Descartes conducted in his Meditations. In defending the claims of the I, one comes face to face with the evil demon. A different 'evil demon' from Descartes admittedly, but no less formidable.
The second lead is a philosophical joke (for those who have the appropriate sense of humour). Old problem of other minds: I know that I exist but I don't know that you exist. New problem of other minds: I know that I exist but YOU don't know that you exist.
Well, I find that funny. I also feel a shiver down my spine. I am speaking of the sense of the uncanny. The subversion of our everyday world by a simple question. As I once wrote, 'It is as if previously everything was up and now everything is down.' It wouldn't make a difference, if everything changed. And yet it does. I am one of a crowd, a speck lost in the thin mouldy film of humanity covering our tiny planet (Schopenhauer). One of a crowd, or alone in a crowd. But we are all alone. Up is down.
I've talked about this paradox before (the paradox of, 'We're all in the same boat...'). Only this time I hear it with a different inflection. The world is not my world, there is also you and your world. But that is still a million miles away from the existence of the Other, or Thou (Levinas, Buber). In Naive Metaphysics, I thought this last step was easy!
