 If this being-of-that-ness is part of the nature of R, a line of reasoning similar to the one that led to the worry about idealism could be run again. If the being-of-that-ness is part of the nature of the relation, then, since ‘that’ refers to the object here, the object too should be part of R’s nature. And since R is part of the nature of the awareness-episode e, the object o too should be part of the nature of e. Thus, the threat of idealism will arise again! (Moreover, if we say that o is not part of the nature of the relation R, but only some further relation R* is, then the same move could be made again, thus launching us on an infinite regress).
