First-Language Judaism vs. Rule-Book Religion: My Conversation with Prof. Moshe Koppel

Rabbi Dr. Levi Brackman sits down with Prof. Moshe Koppel—mathematician, long-time Israeli resident, and author of Judaism Straight Up—to explore what it means to “speak” Judaism naturally instead of consulting a rule book at every turn.

Highlights include:

• Shimen vs. Heidi: two real people who illustrate organic tribal Judaism and cosmopolitan universalism
• Why thick social norms help communities last, and how thin “fairness-only” ethics can fall short
• The role of instinct, family memory, and everyday practice in shaping halakhic decision-making
• How concrete beliefs and abstract theology each serve different emotional and intellectual needs
• A brief look at DICTA, Koppel’s project that applies language-tech tools to classic Jewish texts

If you’re curious about living tradition, social cohesion, and the balance between rules and fluency, this conversation lays out the ideas clearly.
