You can't catch a fly ball if you are unconscious. Nevertheless, nothing need be conceptualized for it to happen. We can say in the abstract then, simply that subjectivity needs to be present for there to be consciousness. In a similar way, objectivity can be understood as an abstraction. Objects are complementary to subjectivity in the constitution of consciousness.
Objects are only objects then because they are complementary to subjectivity.
Common Sense Vs Technical Terminology Subjectivity and objectivity are defined as structures of consciousness, both internal to consciousness. Those are some very fancy terms. The main advantage is avoidance of confusing ambiguity. On the other hand, it is important to connect the analysis of consciousness to common sense, and use of a special analytic language seriously inhibits that connection. So in Generative Realism the choice is to deal with the ambiguity.
