I do not agree with most of modern education, I my mind the thing to concentrate on are Mathematics Physics and the Avi Ezri of Rav Shach  But I would also agree to learning Mechanical Engineering -which after all was what my father father majored in in school. But you might ask, "What if I am not talented in Math?" To answer that question I have mentioned that to some Rishonim, learning Physics and Metaphysics is in the category of learning the Oral Law.  [These would be Rishonim that were going by Rav Saadia Gaon Ibn Pakuda and the Rambam] That means that it is a mitzvah to learn them whether one i talented or not.

 רב לכם בני לוי In the chapters that we read this week in parshat Korah, both Moses  and the congregation of Korach accuse each other of being the rav of the "kelipa"[that is rav *(religious teacher) of the Dark Side] [This is how Rav Isaac Luria explains these verses]. For in the congregation of Korah were the greatest teachers of Torah in that generation as the second Rashi in the Parsha explains--that they were the 250 heads of the sanhedrins

[background note--Korah and his group were against Moses [Moshe], At  the beginning of their revolt they said to moses [''we have had enough of you children of Levi. Literally that is "That is too much of you Children of Levi" But the language also can mean, "You have a Rav (of the kelipa)" and Moses threw at them the exact same accusation "You have a Rav (of the kelipa)"  

One flaw in John Locke and the Declaration of Independence is the assumption that all men are created equal. This is a fiction. Just like in animal species, there is a divergence into different species, so the human species is diverging into separate species. And we know that the Constitution of the USA was never meant to work for  vastly different kinds of groups as the Founding Fathers said openly. It was meant mainly for a homogenous group of people: White Anglo Saxon Protestants. Other groups with a different kind of value system might need a different kind of government. One example is the former Soviet Union, even though it was founded on a flawed system of economics, still the brutality of the later czars gave people the idea that a system that favored working people [the proletariat ]  would be better that being slaves to the parasitic nobles and aristocracy.  And when the system failed, many people felt that they had fallen into chaos, not a liberal free democracy. For there to be any safety to walk on the street, there had to be unofficial war lords in charge of each area of a city in order to preserve peace and order.

 The world is shifting from the USA to the Russian -Chinese alliance. The Chinese space station is a case that already shows this shift. Rewarding merit instead of racial or sexual preference shows up in actual accomplishment.

[This is enough for me to wonder if Hegel actually had some good points as an extension of Kant. There is something odd going on in the USA, and it makes me wonder if perhaps there might be some essential flaw in the system itself? I admit to being somewhat in favor of Hegel because the only Hegel I read was  the Logic part of the Encyclopedia--almost the last thing he wrote which is closely reasoned--rather than the earlier works where most people start. Plus McTaggart who is a formidable proponent of Hegel. But I am not saying either that McTaggart got everything right either--even in Hegel.   

Idea Bava Metzia ch.8-9

Continued from yesterday. Rav Shach   never actually wrote that the argument between Tosphot and the Rambam depends on how you understand the category of a pledge. It seems what he meant was that Tosphot must hold the law of a pledge comes from a decree of the Torah where it is in the case of a loan. Thus it must come only in the case where there is a obligation. Tosphot in fact holds if he would give her a document saying he must give her 100 zuz and say that "You are hereby married to me by this document, and here is a pledge until I give the mana [100 zuz"] she would in fact be by that married. In other words, if he just says, "You are married to me by  a mana that I will give you, and here is a  pledge until I give it," she is not by that married because he has no obligation to give the mana.

But here one can ask: Let the law be that by that statement she is thus married, and then he will be obligated to give her the mana. And thus she is married. 

This is similar to the question on the law that if lashon hara/slander is said in front of three people one is allowed after that to say it. The reason is that since there are already three people making it known, it i considered already known. But let the law be that one can not say it even though it was said in front of three people and then there will not be three people making it known.

 רב שך   never actually wrote that the argument between תוספות and the רמב''ם depends on how you understand the category of a pledge. It seems what he meant was that תוספות must hold the law of a pledge comes from a גזירת הכתוב where it is in the case of a loan. Thus it must come only in the case where there is a obligation. תוספות in fact holds if he would give her a document saying he must give her מאה זוז and say that "You are hereby married to me by this document, and here is a pledge until I give the מנה'" she would in fact be by that married. In other words if he just says "You are married to me by  a מנה that I will give you, and here is a  pledge until I give it," she is not by that married because he has no obligation to give the mana.

But here one can ask: Let the law be that by that statement she is thus married, and then he will be obligated to give her the מנה. And thus she is married. 

This is similar to the question on the law that if לשון הרע is said in front of three people, one is allowed after that to say it. The reason is that since there are already three people making it known, it  considered already known. But let the law be that one can not say it even though it was said in front of three people and then there will not be three people making it known.

רב שך מעולם לא כתב שהוויכוח בין תוספות לרמב''ם תלוי איך אתה מבין את הקטגוריה של משכון. נראה שמה שהוא התכוון היה שתוספות חייב להחזיק שחוק המשכון מגיע מגזירת הכתוב שבו הוא נמצא במקרה של הלוואה. לפיכך היא חייבת לבוא רק במקרה שישנה התחייבות. תוספות מחזיק אם היה נותן לה מסמך שאומר שהוא חייב לתת לה מאה זוז ולומר ש"את נשואה לי בזאת במסמך הזה, והנה משכון עד שאתן את המנה" היא בעצם תהיה על ידי זה שנשוי. כלומר אם רק יאמר "את נשואה לי במנה שאתן לך, והנה משכון עד שאתן", היא לא נשואה בזה כי אין לו חובה לתת את המנה. אבל כאן אפשר לשאול: יהא הדין שעל ידי האמירה ההיא היא נשואה כך, ואז הוא יהיה חייב לתת לה את המנה. ועכשיו היא נשואה. הדבר דומה לשאלה על הדין שאם נאמר לשון הרע בפני שלושה אנשים, מותר לאחר מכן לומר. הסיבה היא שמאחר שיש כבר שלושה אנשים שמודיעים, זה נחשב כבר ידוע. אלא שיהא הדין שאי אפשר לומר זאת אף על פי שנאמר בפני שלושה אנשים, ואז לא יהיו שלושה אנשים שמפרסמים

Kidushin 8. Rambam Marriage chapter 5 halacha 23

If one says to a woman, "You are married to me by a pruta [penny], and here is a pledge until I give the pruta." She is not married because there is no pruta [penny], and there is no pledge. Thus sayeth Rava in Kiduhin. What does this mean, "There is no pledge?" Tosphot holds there is no pledge because there is no obligation to give the pruta. But if had written a document saying that he would give a pruta or had made kinyan sudar [acquisition by a scarf] she would be married, But what is the regular case of a pledge? Is it specifically from a decree of the Torah that there is such a thing as a pledge --. If so, that is only in the case of a loan. But is a pledge is a general sort of thing that a pledge can be given until some obligation is fulfilled? This is how Rav Shach seems to explain the Tosphot.

 But on the other side, there is the Rambam and Rashba that hold she is not married and there is no pledge because nothing of monetary value reached her. The implication of Rav Shach is that this approach of the Rambam and the Rashba goes according to the way of understanding a pledge as being from a decree of the Torah, that it is for a loan. But that does not seem to fit the Rambam and Rashba either. I admit I have been puzzled about this subject for in the case of the Torah, (the case of a loan), nothing of value has reached the lender  either,

So Rav Shach must mean the opposite. A pledge is only in a case of an obligation  as per the decree of the Torah in the case of a loan. and this is the reasoning of Tosphot that if there had been a document obligating him, Then she would be married. And the reasoning of the Rambam and Rashba is that there is in general  an acquiring of a pledge that is simply acquiring an object on condition that the loan is not paid or any other condition. But if so, then in the case of kidushin, why is the pledge any  less than any other pledge that is given on condition? 

So what the Rambam and Rashba mean  is that even though this pledge has a true category of a pledge, still by the fact that it does not remain with her, there is no kidushin. This is the same reason why  a present on condition to return also does not cause a category of a kidushin

If one says to a woman, "You are married to me by a פרוטה and here is a  משכון until I give the פרוטה." She is not married because there is no פרוטה and there is no משכון. Thus sayeth רבא in קידושין ח. What does this mean, "There is no משכון?" And תוספות holds there is no  משכון because there is no obligation to give the פרוטה. But if had written a שטר saying that he would give  פרוטה or had made קניין סודר  (handkerchief)  she would be married. But what is the regular case of a משכון? Is it specifically from a גזירת הכתוב that there is such a thing as a משכון . If so, that is only in the case of a loan. But if a משכון is a general sort of thing that a משכון can be given until some obligation is fulfilled? This is how  רב שך  seems to explain the תוספות. But on the other side, there is the רמב''ם and רשב''א that hold she is not married and there is no משכון because nothing of monetary value reached her. The implication of  רב שך is that this approach of the  רמב''ם and רשב''א goes according to the way of understanding a משכון as being from a decree of the Torah, that it is for a loan. But that does not seem to fit the  רמב''ם and רשב''א either.  I have been puzzled about this subject for in the case of the Torah, (the case of a loan), nothing of value has reached the lender  either, So רב שך must mean the opposite. A משכון is only in a case of an obligation  as per the decree of the Torah in the case of a loan. And this is the reasoning of תוספות that if there had been a document obligating him, Then she would be married. And the reasoning of the  רמב''ם and רשב''א is that there is in general  an acquiring of a משכון that is simply acquiring an object on condition that the loan is not paid or any other condition.

But if so, then in the case of קידושין, why is the pledge any  less than any other pledge that is given on condition? 

so what the  רמב''ם and רשב''א  mean  is that, even though the pledge has a true category of a pledge, still by the fact that it does not remain with her, there is no קידושין. This is the same reason why  a present on condition to return also does not cause a  קידושין

אם אומר לאישה "את נשואה לי בפרוטה והנה משכון עד שאתן פרוטה". היא לא נשואה כי אין פרוטה ואין משכון. כה אומר רבא בקידושין ף ח. מה זה אומר "אין משכון?" תוספות מחזיק אין משכון כי אין חובה לתת את הפרוטה. אבל אם היה כותב שטר שייתן פרוטה או עשה קניין סודר (מטפחת) היא נשואה. אבל מהו המקרה הרגיל של משכנתא? האם זה ספציפית מגזירת הכתוב שיש דבר כזה משכון. אם כן, זה רק במקרה של הלוואה. אבל אם משכון הוא מעין דבר כללי שאפשר לתת משכון עד שתתקיים חובה כלשהי? כך נראה רב שך שמסביר את התוספות. אבל מהצד השני יש את הרמב''ם והרשב''א שמחזיקים שהיא לא נשואה ואין משכון כי שום דבר בעל ערך כספי לא הגיע אליה. המשמעות של רב שך היא שגישה זו של הרמב''ם ורשב''א הולכת לפי דרך הבנת משכון כנגזרה מגזרת התורה, שהיא להלוואה. אבל נראה שגם זה לא מתאים לרמב''ם ורשב''א. התלבטתי בנושא זה כי במקרה של התורה, (במקרה של הלוואה), גם שום דבר בעל ערך לא הגיע למלווה, אז רב שך חייב להתכוון להיפך. משכון הוא רק במקרה של התחייבות לפי גזירת התורה  כגון במקרה של הלוואה. וזהו נימוק התוספות שאם היה מסמך המחייב אותו, אז הייתה נשואה. והנימוק של הרמב''ם ורשב''א הוא שיש בכלל רכישת משכון שפשוט רכישת חפץ בתנאי שההלוואה לא תשולם או כל תנאי אחר

אבל אם כן, אז במקרה של קידושין, מדוע המשכון פחות מכל משכון אחר שניתן בתנאי?

אז מה שהרמב''ם והרשב''א מתכוונים זה שאף על פי שלמשכון הזה יש קטגוריה אמיתית של משכון, עדיין על ידי זה שהוא לא נשאר אצלה, אין קידושין. זו אותה סיבה שגם מתנה בתנאי להחזיר אינה גורמת לקידושין

 Rav Nahman did not hold with learning philosophy nor any secular studies. He echoed Rav Hai Gaon. But this was not the approach of Ibn Pakuda and Rambam. I went with the approach of Rav Nahman for a few years and yet my experiences with the more or less ghetto [frum] ultra religious world gave me reason to  reconsider. And so with due respect to Rav Nahman, I tend to the approach of Ibn Pakuda, Rambam and Gra who all held from the importance of some secular disciplines - but with a lot of limitations. In the long run, I have to conclude that certain philosophers of the ancient Greeks are important, and Kant also. The natural sciences also. However psychology is pseudo  science. See Karl Popper for the reason.

[In the approach of the Rambam, physics and metaphysics are apart of the mitzvah to learn Gemara. in laws of learning Torah where he says divide the learning into three parts--written law, oral law, gemara. and the subjects brought in the first four chapters are in the category of gemara.]
