Dear Rav Eidensohn,
I stumbled across your blog as I was researching the so-called 'dybbuk' phenomena within the Jewish community. It was my sister who reported this story to me that led me to research the possible Torah sources for whether such phenomena ought to be thought of as anything but psychological illness.
As a college student studying philosophy and chemistry, I am always skeptical when I hear of stories which clash with the claims of modern science, medicine and general logic, so naturally I was doubtful about the supernatural claims being made. Your blog provided me with some relief in seeing that this is not something that Jews categorically believe in.
This episode has led me to the following larger-scale questions, however, which still remain unanswered. These questions have been ones which I have been thinking about a tremendous amount lately, and would appreciate any insight you may have.
(1) I did locate a number of sources in Hasidic/'Kabbalistic' literature which develop the idea of the dybbuk. What are we to make of these sources/claims? Especially when being tied to writings as early as the Ramban, how are we to straddle the line between being men of Torah and reformers when discarding claims being made by earlier rabbis? Does the idea of gilgul purportedly espoused by the Ramban entail the existence of Dybukim? (As an interesting aside, Plato, in the Meno and Pheado, seems to endorse a doctrine of reincarnation of souls on purely rational grounds).
(2) What criteria are we to use to determine when to endorse a given supernatural phenomenon and when to repudiate it? Surely there are certain supernatural events (Har Sinai, Kriyas Yam Suf, etc.) which we take quite literally as having occurred. What justifies our endorsement of these events over events such as dybukkim?
(3) Are the truths revealed by the Torah the same truths that would be arrived at by perfected human reason?
(4) Is the study of secular philosophy advantageous or detrimental in becoming a perfected Jew?
(5) If the claims about dybukkim are false (which I take them to be), then how do we explain how such ideas have crept into our Mesora under the veil of true kabbalah? Why are such ideas endorsed by supposedly important and learned rabbis? And, more importantly, why don't more Rabbis and community leaders who are aware of the spurious nature of such claims publicize the fraud?
Over the years I have formed answers of my own to some of these questions, but I currently find myself in a position where I am in need of further grounded Rabbinic insight to clarify and solidify my stance towards yahadus and my own outlook as a college student and Jew.
