If they really were the innermost sanctuary, the _ultimate_ one of all the selves whose being we can ever directly experience, it would follow that _all_ that is experienced is, strictly considered, _objective_; that this Objective falls asunder into two contrasted parts, one realized as 'Self,' the other as 'not-Self; 'and that over and above these parts there _is_ nothing save the fact that they are known, the fact of the stream of thought being there as the indispensable subjective condition of their being experienced at all. But this _condition_ of the experience is not one of the _things experienced_ at the moment; this knowing is not immediately _known_. It is only known in subsequent reflection. Instead, then, of the stream of thought being one of _con_-sciousness, "thinking its own existence along with whatever else it thinks," (as Ferrier says) it might be better called a stream of _Scious_ness pure and simple, thinking objects of some of which it makes what it calls a 'Me,' and only aware of its 'pure' Self in an abstract, hypothetic or conceptual way. Each 'section' of the stream would then be a bit of sciousness or knowledge of this sort, including and contemplating its 'me' and its 'not-me' as objects which work out their drama together, but not yet including or contemplating its own subjective being. The sciousness in question would be the _Thinker_, and the existence of this thinker would be given to us rather as a logical postulate than as that direct inner perception of spiritual activity which we naturally believe ourselves to have. 'Matter,' as something behind physical phenomena, is a postulate of this sort. Between the postulated Matter and the postulated Thinker, the sheet of phenomena would then swing, some of them (the 'realities') pertaining more to the matter, others (the fictions, opinions, and errors) pertaining more to the Thinker. But _who_ the Thinker would be, or how many distinct Thinkers we ought to suppose in the universe, would all be subjects for an ulterior metaphysical inquiry.
