What is it you do other than apply a meta-filter to present awareness? This filter seeks to retain only reality, truth, ground or some such concept, or to reject the objective or hypothetical. All of this is very clumsy although not without a certain effectiveness. Perhaps it is limited to the same degree as it succeeds, since the filter itself won't pass through the filter. If it is a meta-filter then it needs to be a meta-meta filter etc. Or maybe it could be called a meta*-filter, the star signifying that it is the direct limit of all meta-moves. (Better if it could be the inverse-limit.) What is more interesting is when and how it fails. That would likely be the co-meta-filter, a sort of negative capability for staying attuned to the complement, that is the residual failure of all such filter games.
