I would assume that the kind of wisdom that Rav Nahman says comes from the Empty Space is Philosophy. I mean to say that there is something odd about philosophy in the first place that seems to retract common sense away from people, and yet does not qualify as simply a false or man made wisdom with no connection to reality. What I mean is that something like psychology is simply pseudo science and a result of its practitioners delusions and their own childhood experiences. There is nothing real or objective about psychology in the first place. But philosophy is not like that. It deal with real questions, but questions that seem to have contradictory answers and which leads into some kind of mental traps.
Psychology is insane people pretending to be doctors. But philosophy takes sane people and makes them insane.
[That is in its effect. On the other hand, it does appear that philosophy can help to limit or cancel other kinds of delusions. Particularity religious delusions. So is it possible to find some kind of balance? We see Robert Hanna in fact demolished 20th century analytic philosophy in its entirety--simply by pointing out its circular reasoning and other logical fallacies. But his suggestion of "Forward to Kant" seems difficult to accept since Kant him is open to many schools of thought, particularity Neo-Kant [Marburg], Leonard Nelson, Hegel.
