I think it is exactly what transcendental subjectivity does for a living. That's its job, to overcome objectivity, to consume it, and become wholeness. Sartre was sure the project of transcendental motivation was doomed, because objectivity can never exist within subjectivity. Well, that is true enough, but in Generative Realism, objectivity can become subjectivity, and subjectivity can actually become objectified, a reciprocal pair of processes called ontological transitivity . It is not so unusual.
Day becomes night, and night becomes day, and that seems to work alright.
So it is not crazy for subjectivity to be motivated to become objectivity, if it can transform objectivity into itself. The urge of subjectivity to consume objectivity in that way is the engine of motivation in transcendental consciousness. The dynamic tension of transcendental subjectivity trying to overcome its separation from the ideal of objective wholeness is genuine and authentic. Sartre's moral implication that there is something wrong with subjectivity trying to do that, is not justified. He just declares it to be wrong.
