Take your most general, most inclusive category: being, event, reality, cosmos, life, mind, happening - get the feel of it, its vastness, its embrace of everything, of every experienceable and every beyond. Whatever it is it is your category and so doesn't apply to you, you are outside it. Admittedly it takes a special way of understanding it for this to be evident, but it is just that way of understanding it that it truly means. But what if it seen as not your category but that of an other, or the most generalised other? That question answers itself. What is that most inclusive category if not precisely the sum (the Cartesian sum or tensor product) of all seeings and being seen. The you that is so simply outside of it is not what you think you are.
