Mishneh Torah, Torah Study 4

Sugya Map

• Issue: The permissibility of learning Torah from a teacher who lacks proper moral or religious conduct.
• Nafka Mina(s): Does the prohibition apply universally, or are advanced students (גדולים) exempt due to their ability to discern truth from falsehood? This impacts contemporary Talmud Torah pedagogy and the value placed on a teacher's character.
• Primary Sources: Mishneh Torah, Hilchot Talmud Torah 4; Chaggigah 15b; Malachi 2:7.

Text Snapshot

The Rambam states: "וכן הרב שאינו הולך בדרך טובה, אף על פי שהוא חכם גדול וכל העם צריכין לו, אין מתלמדין ממנו עד שישוב למוטב." (Mishneh Torah, Hilchot Talmud Torah 4:4, per Sefaria numbering, or the statement associated with footnote 10 in the provided text).

• Dikduk/Leshon Nuance: The phrase "אין מתלמדין ממנו" is passive and universal, implying no one should learn from such a teacher. The Rambam makes no explicit distinction between students of differing intellectual or spiritual stature.

Readings

• Peri Chadash (ad loc. s.v. v'chen haRav she'eino) briefly notes the common kushya from Chaggigah 15b, which permits a gadol (like R' Meir) to learn from an unfit teacher (Acher). He resolves it by asserting the Rambam views R' Meir's capacity ("רימון מצא תוכו אכל קליפתו זרק" – Chaggigah 15b) as unique, and thus, the Gemara's distinction doesn't apply to ordinary sages, even great ones.
• Seder Mishnah (ad loc. s.v. v'chen haRav she'eino) argues the Rambam does implicitly agree with the Chaggigah's distinction. The underlying reason for the prohibition is the fear of being influenced by corrupt ideas. However, for a gadol whose intellect is robust enough to discern truth from falsehood, the Rambam himself allows delving into the perilous depths of Ma'aseh Bereshit and Ma'aseh Merkavah (Hilchot Yesodei HaTorah 1). By kal v'chomer, such a gadol would be permitted to learn from an unfit teacher where the danger is arguably less acute. The Rambam simply didn't need to specify this here.

Friction

• Kushya: The Rambam's seemingly universal prohibition "אין מתלמדין ממנו" (Hilchot Talmud Torah 4:4) directly clashes with Chaggigah 15b, which explicitly permits a "gadol" to learn from a problematic teacher, using R' Meir's example with Acher.
• Terutz: The Seder Mishnah's approach offers the most compelling resolution. The Rambam's omission of the "gadol" exception is not a rejection but a reflection of its extraordinary nature. The concern is himshichut (being drawn after bad ideas). A true gadol, defined by the Rambam in Hilchot Yesodei HaTorah 1:8-12 as one capable of discerning profound truths without straying, is inherently immune to such influence. The very qualities that permit study of Ma'aseh Merkavah would, a fortiori, permit learning from an otherwise unfit teacher.

Intertext

• Chaggigah 15b: The classic source discussing R' Meir learning from Acher, leading to the dictum "ר' מאיר רימון מצא, תוכו אכל, קליפתו זרק" (R' Meir found a pomegranate, ate its inside, and discarded its peel).
• Mishneh Torah, Hilchot Yesodei HaTorah 1:8-12: The Rambam's rules for studying esoteric topics (like Ma'aseh Merkavah), stressing that only a "gadol v'chacham" may engage, lest one come to heresy.

Psak/Practice

The Rambam's psak, particularly if interpreted like the Peri Chadash, leans towards a highly stringent approach. In practice, the bar for being considered a "gadol" capable of learning from an improper teacher without spiritual harm is exceedingly high, effectively rendering the permission a theoretical rarity. Thus, the normative halachic practice is to avoid learning from a teacher whose conduct is not "כמלאך ה' צבאות" (Malachi 2:7, cited by Rambam in 4:5).

Takeaway

The Rambam prioritizes the spiritual integrity of the student and the sanctity of Torah over the pursuit of knowledge from any source. A teacher's character is not merely an accessory but an indispensable component of Talmud Torah.
