Speaking in Kabbalist language, objective thought is confined to Assiyah.
Material and sensory objects are confined to Malkhut d’Assiyah; subjective objects to Yesod, Hod, Netzach, Gevurah and Chesed d’Assiyah; objective truth to Binah d’Assiyah; objectivity itself to Chokhmah d’Assiyah.
(Psychologism everts the relationship of subject and object. It is the futile attempt to grasp truths of Yetzirah in the inadequate terms of Assiyah. Psychologized religion is antireligion.)
Until one intuits the transcendent source of all the material and immaterial objects, one knows nothing of Yetzirah. Yetzirah can only be known by apperceptive participation in various modes of existence in Yetzirah. (This is the radical pluralism of hermeneutics.) Yetzirah is known solely by its fruits in Assiyah.
But the indirect experiencing of Yetzirah can open awareness to Beriyah — but only if we learn how nothingness works. It is natural to know nothing of nothingness.
Once we catch Beriyah in the act of creation ex nihilo, we become exnihilists.
