Text Snapshot

"הגלגל התשיעי הזה חילקוהו חכמים הראשונים לי"ב חלקים וקראו לכל חלק וחלק שם... אלו הן המזלות..." (MT Yesodei HaTorah 3:5)

• Dikduk/Leshon: "חילקוהו חכמים הראשונים" – denotes human categorization of the mazalot (Zodiacal constellations), not inherent divine divisions of the ninth, star-bearing sphere. "כל הכוכבים והגלגלים כולם בעלי נפש ודעה והשכל הם וחיים ועומדים ומכירין את מי שאמר והיה העולם." (MT Yesodei HaTorah 3:10)
• Dikduk/Leshon: Attributes consciousness, intellect, and soul (nefesh) to celestial bodies, distinct from their physical properties, ascribing them a form of divine recognition and praise.

Readings

Peirush on MT 3:1:1

This commentary clarifies Chagiga 12b's distinction: R' Yehuda's two rakia are physical firmaments; Reish Lakish's seven include spiritual, non-corporeal realms (e.g., Zevul for Michael's altar). This resolves the apparent contradiction by defining "physical shamayim" as solely the star-bearing rakia, while higher "heavens" are spiritual.

Ra'avad on Hilchot Teshuvah 5:5

Challenging Rambam's strong dismissal of mazal, Ra'avad states, "The words of this man are close to saying that there is no mazal at all, and this is not correct." This highlights a fundamental disagreement among Rishonim regarding the extent of celestial influence on human affairs.

Friction

Kushya

How does Rambam's detailed description of mazalot reconcile with his unequivocal condemnation of astrology as "empty words and lies" (Avodah Zarah 4:7, Shemonah Perakim 8) and the Talmudic principle of Ein Mazal LeYisrael (Shabbat 156a)? If mazalot have no influence, why include their description in Yesodei HaTorah?

Terutz

Rambam distinguishes descriptive astronomy from prescriptive astrology. Mazalot are human classifications ("חילקוהו חכמים הראשונים") for mapping stellar movements, essential knowledge for understanding Ma'aseh Bereishit and thus God's wisdom. Attributing deterministic influence or fortune, however, constitutes Avodah Zarah or darkei ha'Emori, which is anathema.

Intertext

• Chagiga 12b: The Gemara's discussion of the seven rakia (e.g., Zevul housing Michael's Beit Hamikdash) informs the commentary's understanding of the multiple meanings of shamayim, separating physical from spiritual realms.
• Shabbat 156a: The dictum "אין מזל לישראל" ("There is no mazal for Israel") is the foundational Talmudic source for rejecting astrological determinism, informing Rambam's steadfast stance despite his extensive astronomical descriptions.

Psak/Practice

Rambam's approach provides a crucial meta-psak heuristic: rigorously pursue scientific truth (even from "wise men of Greece," MT Kiddush HaChodesh 17:24) in understanding God's creation, while unequivocally rejecting superstitious beliefs (like astrology) that undermine hashgacha pratit and free will.

Takeaway

The Rambam's cosmology integrates scientific observation with theology: understanding creation is vital, but deterministic astrological influences must be rejected.
