Does this mean that a person is not permitted to question his Rebbi's
teachings? If he is permitted to question his Rebbi's teachings, in one what
way must it be done in order not to be considered "arguing?"
(a) RASHI comments that one who argues with his Rebbi is one "who argues on
his Yeshivah." What does this mean?
The BE'ER SHEVA first explains that Rashi is emphasizing that even one who
argues with his Rebbi's other students (his "Yeshivah") is considered to be
arguing with the Shechinah. The Gemara learns this from Korach, who did not
challenged the position of Moshe (the Rebbi), but who challenged the
position of Aharon and his sons (the other students of Moshe).
The Be'er Sheva prefers, though, a different explanation for the words of
Rashi and for the meaning of "ha'Cholek Al Rabo," one who argues with his
Rebbi. He says that Rashi understands the Gemara the way that the RAMBAM
understands it. The Rambam (Hilchos Talmud Torah 5:2) describes one who
argues with his Rebbi as "one who establishes a place in which he teaches
and lectures without the consent of his Rebbi, and his Rebbi is alive, even
though he is in a different country." That is, the Gemara is not referring
to a student who argues with his Rebbi regarding a specific issue in
Halachah. Rather, the Gemara is referring to a student who establishes an
entirely separate school apart from his Rebbi's. This is also the ruling of
the SHULCHAN ARUCH (YD 242:3). The Be'er Sheva adds that the TERUMAS
HA'DESHEN (#238, and cited by the REMA YD 242:3) rules that a student is
allowed to argue with his Rebbi with regard to a Halachic ruling when he
provides proof to support his view. (The LEVUSH seems to imply that this
applies only in singular situations. When he quotes the Terumas ha'Deshen,
he writes that a student may argue with his Rebbi "in a certain, single
ruling," implying that a student may not argue regularly and often. The
ARUCH HA'SHULCHAN further qualifies the words of the Rema as applying only
where one's Rebbi eventually agrees to his argument.)
The Be'er Sheva elaborates on this and proves that it is permitted for a
student to argue with his Rebbi in matters of Halachah. He says that this
has been the way of learning Torah throughout all of the generations, and he
cites many examples, including, among the Tana'im, Rebbi, who argues with
his father and teacher, Raban Shimon ben Gamliel; among the Amora'im, Rava,
who argues with his teacher, Rabah; and among the Rishonim, the Ashiri who
argues with his teacher, the Maharam, and the Tur who argues with his father
and teacher, the Rosh. The Be'er Sheva says that the practice of arguing
with one's Rebbi in the manner that has been done throughout the generations
applies whether his Rebbi is present or not, whether others side with him or
not, and whether the student is young or old (see TOSFOS, Nidah 14b).
However, the Be'er Sheva questions his explanation from the Gemara in
Kidushin (end of 31b) that states that "one may not contradict the words" of
his father, and which the Poskim explain refers to arguing with his Halachic
ruling, and which applies to one's Rebbi as well (SHULCHAN ARUCH YD 242:16).
This clearly refers to arguing with the ruling of one's Rebbi! (See BEIS
YOSEF there.)
The Be'er Sheva suggests that the Gemara in Kidushin means that one may not
contradict the words of his father (or Rebbi) in a confrontational manner,
by saying, "No, that is not correct," but rather he must express his
disagreement in a respectful manner, as the Gemara earlier in Sanhedrin
teaches (81a).
Alternatively, the Be'er Sheva suggests that the Gemara in Kidushin does not
mean (as Rashi and other Rishonim explain) that one may not argue with the
Halachic ruling of one's father or Rebbi. Rather, it means that one may not
contradict the mundane, non-Halachic statements of one's father or Rebbi.
One is certainly permitted to argue (in a respectful manner, of course) with
the Halachic ruling of one's Rebbi.
He proves this from the Gemara in Kidushin (30b) which derives from verses
(Tehilim 127:5 and Bamidbar 21:14) that "even a father and son, or a Rebbi
and student, learning together become like enemies to each other, and they
do not move from there until they become beloved to each other." The Gemara
is describing a Rebbi and a student arguing in Halachic matters, and it
sanctions such arguments when done for the sake of clarifying the truth
about a Torah matter. He cites a Teshuvah of the ROSH (Teshuvos, 55:9) who
writes that when the clarification of the Torah is involved, one is
obligated to argue.
(b) The SHACH disagrees with the Terumas ha'Deshen. He quotes the MAHARIK
(Shoresh 170) who says that a student may argue with his Rebbi only when he
has reached an equal level of scholarly as his Rebbi. Otherwise, he may not
argue even if he has proofs supporting his argument. He says that the proofs
that the Terumas ha'Deshen cites to support his view are refutable, since --
in each of the cases of students arguing with their teachers -- the Rebbi
might have given explicit permission to student to argue with him, or it
might be referring to when the student argued with his Rebbi's ruling after
his Rebbi's death. (He does mention that the matter needs further
elucidation.) It is important to note that even the Shach is stringent only
in a Rebbi-student relationship, but not in the relationship of a "Talmid
Chaver" who is "close to being as great as his Rebbi" and thus may argue
with him.
(c) The RADVAZ asserts that all the proofs from the Gemara and throughout
the generations that a student may argue with his Rebbi apply only with
regard to theoretical matters, but not with regard to Halachah l'Ma'aseh.
The student is not allowed to rule in opposition to his Rebbi's ruling.
The SHE'EILAS YA'AVETZ (#5) says that this is also the opinion of the
Terumas ha'Deshen himself, and he writes a strong proof for this. The
Shulchan Aruch, Rambam, and other Poskim all write the Halachah that a
student who issues a Halachic ruling in the presence of his Rebbi ("Moreh
Halachah Bifnei Rabo") is Chayav Misah. If it is true that a student is
permitted to argue with his Rebbi even with regard to the actual Halachah,
then how can it be that he would be Chayav Misah for issuing a Halachic
ruling, which does not even contradict his Rebbi's ruling, in the presence
of his Rebbi? It must be that the Terumas ha'Deshen is referring to
discussing the theoretical aspects of the Halachah, and that is when a
student is allowed to argue with his Rebbi, and he is not referring to the
actual Halachic ruling.
The She'eilas Ya'avetz agrees, though, that a person whose wisdom is
comparable to his Rebbi's may argue even in Halachic matters, as we find
many cases of such arguments throughout the generations (see IGROS MOSHE YD
3:88).
The She'eilas Ya'avetz states further that a student may not even rule *for
himself* and conduct himself in a stringent manner in accordance with his
own view of the Halachah, when his Rebbi is lenient. However, the MAHARSHAL
(cited by the MAGEN AVRAHAM and the MISHNAH BERURAH OC 63:7) rules that one
is allowed to be stringent against the opinion of his Rebbi if he has proofs
which refute his Rebbi's lenient ruing. RAV CHAIM KANIEVSKY, shlit'a,
understands that the Mishnah Berurah implies that a student is allowed to be
stringent even in front of his Rebbi.
