Mishneh Torah, Positive Mitzvot 1-248

Sugya Map

• Issue: The Rambam's enumeration of Mitzvot Asseh commences with "לדעת שיש שם אלוה" – the obligation to know God. This raises fundamental questions about the nature of yediah (knowledge) versus emunah (belief) in the context of a divine command. Is it a passive assent or an active, intellectual pursuit?
• Nafka Mina(s): What level of intellectual inquiry is required? Does this mitzvah demand philosophical investigation (iyun) from every individual, or is a simpler form of belief sufficient? How does this initial mitzvah sichlit (intellectual commandment) inform our understanding of the entire corpus of mitzvot?
• Primary Sources: Mishneh Torah, Positive Mitzvot 1; Sefer HaMitzvot, Positive Mitzvah 1; Hilchot Yesodei HaTorah 1:1-2.

Text Snapshot

"הראשונה ממצות עשה היא המצוה לדעת שיש שם אלוה שנאמר 'אנכי ה׳ אלהיך'" (Mishneh Torah, Positive Mitzvot 1)

• Dikduk/Leshon Nuance: The choice of "לדעת" (to know) is paramount. It implies a deeper, more cognitive grasp than "להאמין" (to believe). The Rambam uses a verb of active cognition, suggesting an intellectual process rather than mere acceptance. The prooftext, "אנכי ה׳ אלהיך" (Exodus 20:2), is not a command to believe, but a declarative statement of existence, which then forms the basis for the commanded knowledge.

Readings

1. Rambam (Hilchot Yesodei HaTorah 1:1-2): Elucidates this mitzvah as an active intellectual obligation, demanding contemplation (iyun) of God's existence and attributes through His creations. He posits that this knowledge is the very foundation of all other mitzvot.
2. Sefer HaChinuch (Mitzvah 25): Echoes this sentiment, emphasizing that the mitzvah entails understanding God's existence and unity, seeing it as the root of faith and a continuous intellectual process of recognizing His greatness through the natural world.

Friction

• Kushya: If "knowing God" necessitates rigorous philosophical inquiry, how can it be a mitzvah incumbent upon every Jew, including those without the intellectual capacity or opportunity for such deep study? Is a philosopher's mitzvah equivalent to that of a simple laborer?
• Terutz: The Rambam himself addresses this implicitly in Hilchot Yesodei HaTorah 1:1. The mitzvah is to know God to the best of one's ability. For the masses, this may be a firm, informed belief passed down through tradition. For the intellectually gifted, it demands profound, systematic inquiry, ascending the ladder of knowledge. The chiyuv (obligation) is universal, but its hiddur (beautification/depth) is individual.

Intertext

• Deuteronomy 4:39: "וְיָדַעְתָּ הַיּוֹם וַהֲשֵׁבֹתָ אֶל לְבָבֶךָ כִּי ה' הוּא הָאֱלֹקים בַּשָּׁמַיִם מִמַּעַל וְעַל הָאָרֶץ מִתָּחַת אֵין עוֹד." ("Know therefore this day, and take it to your heart, that the LORD is God in heaven above and on the earth beneath; there is no other.") This verse explicitly links active "knowing" (yediah) with internalizing it "to your heart" (vehahashavta el levavecha), reinforcing the Rambam's emphasis on cognitive apprehension.
• Yeshayahu 43:10: "לְמַעַן תֵּדְעוּ וְתַאֲמִינוּ לִי וְתָבִינוּ כִּי אֲנִי הוּא." ("That you may know and believe Me, and understand that I am He.") Here, yediah (knowing) precedes emunah (belief) and binah (understanding), suggesting that a cognitive foundation underpins and deepens faith.

Psak/Practice

This foundational mitzvah underscores that emunah is not blind faith but rather informed knowledge. It sets a meta-psak heuristic that the intellectual pursuit of God is not merely an optional hiddur, but an intrinsic component of religious observance. The Rambam's entire philosophical project, including Moreh Nevuchim, can be seen as a comprehensive guide to fulfilling this primary mitzvah.

Takeaway

The Rambam's placement of Yediat Hashem as the prime mitzvah asserts that a vibrant religious life is rooted in active, intellectual engagement with the Divine, proportional to one's capacity, rather than mere rote observance.
