Computational, or perhaps even just relational theories of mind or of fundamental physics are essentially Berkleyan idealism, since in them to be is to be perceived, where the relations may stand in for the perceiving. That accounts for the being of beings, but what about the being of the perceiving? Somehow this must be left out, the aperture is to small for soul to get through, so that such theories cannot account for the difference between formal relations (or computations) and 'actual' ones. In other terms what this line of thought brings you face to face with, if only for a moment, is the forgetting of being. So much dances around this ontological difference without being able to touch it. The closer you get to it the more it recedes.
