The goal of this final chapter is to show the ontological shift between the Logische Untersuchungen and the volumes of the Ideen. There is, as we shall see, a sort of Copernican transformation of the basic doctrines and concepts of the former work. In this, the position of the Ideen stands as the result of the transformation. Both the latter work and the transformation itself can be looked upon as a motivated response to the difficulties we have uncovered in our last two chapters.
