Steven Dutch said : I can think of any system that can not be misused."

The issue of Torah scholars that are demons Rav Nahman brings in the very last Torah lesson of his life. So in the thought of Rav Nahman this issue is of great importance. היינו תלמידי חכמים שדיים יהודאיים.  In the thought process of Rav Nahman the point is that he is actually thinking of real "shadim" or what might be called minor deities with real powers--even miraculous powers.
Though it is clear anyway that that is exactly what the gemara itself holds. As the issue applies to Torah scholars what seems that Rav Nahman is getting at is that the very inner essence of these people has been changed from a human essence to an essence of a demon. Kind of a frightening thought I must add.

Though I have mentioned that this is actually brought in the Gemara itself and even the Mishna yet seems to be an unpopular subject. You don't usually hear about it much--unless you happen to read Rav Nahman's books. Because in the Gemara itself it is mentioned I think just once.

The main thing here is not that this is a reflection on Torah itself. Rather like the Roman saying: "Abuse does not cancel use." Or as Steven Dutch said : I can not think of any system that can not be misused."

The way to understand this is that of בירוד. You have to separate the wheat from the chaff. The way to go about this is a kind of process desired by Hegel. That is in every concept is contained aspects of its opposite until you get to the ultimate Truth. So you need some kind of sublimation to get to the truth. That is in short you find what is right in both and then you can make a synthesis.
[I know this is hard to see in Hegel. I understood this only after learning McTaggart's commentary of Hegel's Logic

Sometimes you have one person who embodies a certain value -like the Gra would embody the value of learning Torah.

With Hegel it is important to see that the process of the dialectic is  a process which leads to the truth. [John Mctaggart [philosophy] makes this clear.] Sometimes you have one person who embodies a certain value -like the Gra would embody the value of learning Torah. Or Rav Israel Salanter the value of Musar. The question is how to combine these different values in a practical way for oneself. 

to critique the claim that a communist society would come up with all the good stuff of capitalism and more

I mean to to critique the claim that a communist society would come up with all the good stuff of capitalism and more. But no significant invention shows that claim to be not true.

Not one invention the whole 70  years of the USSR. The spies used to call Silicon Valley "the laboratories of the KGB" because that is where all the tech of the USSR came from. From spies stealing American inventions. [I know because one of my friends was a KGB agent, and I knew him well, and his family. I even taught how to play violin to his daughter.]
In fact, the very corporation my Dad was an inventor in was penetrated by the KGB. [The film, the Falcon and the Snowman was based on this.] [The incident happened after my Dad left the company. He at first had made the infrared detection part of the USA spy satellites. After that my dad continued working for that company --- on laser satellites. But after a few years of that he left.] 

the problem of people that are not physicists commenting on physics.

I also noticed the problem of people that are not physicists commenting on physics. However I also noticed the problem with physicists commenting on physics. That is to say sometimes it is hard to decided who really is the top and who just seems like they know.

Take for example Husserl who knew Physics of his time well. But that did not put him into the same league as an Einstein or Heisenberg. So when t comes to commenting and understanding Physics from a larger picture it turns out that Leonard Nelson was probably a lot better than Husserl. Even though Nelson was not in fact trained as a physicist.
But that does not mean that Husserl was a crackpot. Rather it simply means one has to recognize his own level of experience. Not assume one knows more than he does. Too many smart people over estimate their own abilities. 

Whether in terms of learning Gemara Tosphot and Maharsha or whether in terms of Physics, I think that there is no question that both "Bekius" (fast learning) and "Iyun"(in depth) are needed.

Clearly Rav Nahman was on the side of going fast. Saying the words just once and in order and going on as fast as possible.  And clearly at Shar Yashuv [Rav Freifeld's in NY] and in all places founded on the Gra, the emphasis is on the in depth approach.

But to me it seems clear that the Mir in NY settled on the path of balance. The morning was devoted to "iyun". There that meant preparing for the class of the four roshei yeshiva. And their classes were in fact amazingly deep. The classes were much more than going over Rav Haim of Brisk or R. Akiva Eigger. For some reason the roshie yeshiva had a new idea to add every day. [It was akin to taking classes in Physics from Richard Feynmann or Einstein.] I assume that this was because they had spent all their lives up until about the age of 50 simply preparing. So by the time they became teachers they had plenty of new idea every single day to go into the depths of Rav Haim Soloveitchik. 

The afternoons and evenings were for fast learning.

Rav Avraham Abulafia

Rav Avraham Abulafia for some reason is not as well known as one would expect. On one hand his books were never published until a few years ago. But he was thought to be one of the greatest mystics of the Middle Ages and is quoted at length by the Remak and Rav Haim Vital.

[The fourth section of Shaarai HaKedusha of Rav Haim Vital itself was never published until recently but that is the section of his only Musar book that explains how to come to "Ruach HaKodesh" [the Divine Spirit] and it is based totally on Rav Avraham Abulafia.

אמונת חכמים ["faith in the wise"] is in fact an important principle for me, so I take it as an axiom to believe the wise. The only question is how to decide who comes under that category. [This great importance of faith in the wise comes from Pirkei Avot but is emphasized by Rav Nahman of Breslov.


[The basic story with Rav Abulafia is the well known event that he went to debate with the pope. The pope left orders that when Rav Abulafia would reach the gates of Rome that he would be arrested. But for some reason people that tried to arrest him died suddenly.]

So Torah is not meant to be a profession.

There is an important commandment to learn Torah. The basic idea is that when there there is another commandment to do that no one else can do, then one is able  to stop learning and then to do the other commandment, and then get back to learning Torah. ["Able" but not obligated according to the Gra]] Otherwise anything one does besides learning Torah come under the category of "Bitul Torah".[Not learning Torah when one is able comes under the category of כי דבר השם בזה הכרת תכרת הנפש ההיא הכרת בעולם הזה תכרת בעולם הבא עיין בנפש החיים ]

[However there is a large array of commandments that are in fact impossible to do by others. For example ונשמרתם מאד לנפשותיכם. פרו ורבו ויותר [watching your health. Having children, etc.]
There is however an important caveat [condition]--not to be making money by means of Torah. Using Torah for money does seem to detract from the value of the commandment. How much so is unclear to me. But in any case, it certainly is undesirable.

So Torah is not meant to be a profession. [See the commentary of Maimonides [Rav Moshe ben Maimon on Pirkei Avot chapter 4. לא קרדום לחפור בהם ... ואשתמש בתגא חלף.] [That statement of Hillel comes up in the first chapter of Pirkei Avot also but that is not where the Rambam put his long comment on it but rather in chapter 4.]

 So where  does Math and Physics fit in with this? I would have to say that they are in the category of learning Torah and are not just for Parnasa [making a living]. This I saw hints of in Rishonim like the Musar book Obligations of the Heart. But quite openly in the Rambam in Yad HaChazaka and the Guide.
