    WHY 18
    Forty

    The year 1840 was a turning point: the Industrial Revolution peaked, the Damascus Affair sparked Jewish unity, and modernity opened new paths for enlightenment. Mystics called it the moment that “the gates of wisdom would open.” For us, 1840 is a symbol of how global upheaval can lead to a reimagined world. Today, we face another “1840 moment”—troubled by tech disruption, mental health crises, and declining faith—that calls for bold questions, timeless sensitivity, and modern sensibilities. That’s what 18Forty is here to explore.

  • Prayer & Humanity

    How Did Modernity Change Jewish Prayer?

    Modernity brought sweeping changes to the Jewish community—and prayer was not immune, not in Reform, Reconstructionist, Conservative, or even Orthodox communities.
  • Prayer & Humanity

    The Siddur Has a Lot of Prayers. Where Did They Come From?

    Between early prayer books, kabbalistic additions, and the printing press, the siddur we have today is filled with prayers from across history.
  • Prayer & Humanity

    Did All Jews Pray the Same in Ancient Times?

    Jews from the Land of Israel prayed differently than we do today—with marked difference. What happened to their traditions?
  • Prayer & Humanity

    Who Wrote the Siddur?

    I’ve searched high and low for an accessible English book or essay addressing the development of the siddur, but my findings are few. This series of essays is my attempt to fill the gap.
  • Origins of Judaism

    The History of Halacha, from the Torah to Today

    Missing from Tanach—the Jewish People’s origin story—is one of the central aspects of Jewish life: the observance of halacha. Why?
  • Origins of Judaism

    The Reform Movement Challenged the Oral Torah. How Did Orthodox Rabbis Respond?

    Reform leaders argued that because of the rabbis’ strained and illogical interpretations in the Talmud, halachic Judaism had lost sight of God. Was that true?
  • Origins of Judaism

    Why the Confusion? On Disputes in the Oral Torah

    If legal codes tell us the laws, then the Mishna is less like a legal code than a record of disagreements about the law. Why is that?
  • Origins of Judaism

    Divinity and Humanity: What the Jewish Sages Thought About the Oral Torah

    Our Sages compiled tractates on the laws of blessings, Pesach, purity, and so much more. What did they have to say about the status of the Oral Torah?
  • Origins of Judaism

    What Are the Origins of the Oral Torah?

    A bedrock principle of Orthodox Judaism is that we received not only the Written Torah at Sinai but also the oral one—does that mean it can’t change?
