There is the getting around in a world, this goes on more or less well by way of a familiar doubling of things and the mental representations of things - with the mental here standing for a naturally double-sided class of things. The notion of thinghood, or better of matters, res, does its work as the fulcrum of this process and carries with it a lot of unprovable metaphysical presumption about the being of these objectives. Actually it doesn't have to go as far as metaphysics, these things could be real or ideal or something else without impairing the effectiveness of ongoing internal relations, without challenge to certain much broader logical assumptions such as the law of identity, A = A. The logic would be confirmed under any given view of what is real, as the constraints on any possible metaphysics, and indeed replacing the need for any metaphysics at all. In all of this however the status of the subject, or consciousness, or the experiencer, remains mysterious. It does not conform to the constraints that define matters or events, or whatever is taken to be primary. (It) appears therefore as a mystery to be solved even though it is strikingly insoluble in any such terms. The possibility remains of 'flipping the script' - take the subject or experiencer or consciousness, not under any name, to be basic reality and see the objective as the mystery. This requires an intense 'escape velocity' of imagination. It goes against the grain of the mental, but the initial result, that the objective is utterly enigmatic and that the general constraints that define metaphysics are groundless fantasms, is not so hard to reach.
