Knowing does not arise in isolation but emerges from the object. Therefore, the object is the foundation of knowing. But the object does not stand alone; rather it assumes its name in dependence upon being known. Therefore, knowing is the foundation of the object. Therefore, without the object there is nothing to elicit knowing, and without knowing there is nothing to illuminate the object….One cannot say the object comes first and knowing follows, or that knowing comes first and the object follows, or that they are simultaneous. One can only speak of the interdependence of the object and knowing.
