Purim is next Monday evening and Tuesday—a day of immense joy, spiritual disruption, and a unique religious mandate. To understand the depth of this mandate, I’ve always come back to an oft-repeated anecdote I heard during my years at the Brisk yeshiva in Israel. It’s a story that perfectly illustrates a core intellectual concept, one that has been foundational to Torah scholarship across the ages.
After a decade of singular dedication to study, Velvel decided it was time to return home and begin to earn a living. He went to take his leave from the Rosh Yeshiva (RY). In the classic style of the Yeshiva world, the RY concluded their leave-taking with a customary challenge: “Velvel, you have been with us for ten long years. Share a ‘chiddush,’ a novel insight or new idea, that you learned during your time here.
Velvel was caught completely off-guard. Unable to produce the requested chiddush, he remained silent, visibly uncomfortable. After a long, deliberate pause, the Rosh Yeshiva’s eyes held a look of profound satisfaction. “Very well, Velvel,” he declared. “You have truly learned a great deal.” He then continued in Yiddish: “bei untz lerent men vos nisht tzu zugen” (here, we teach our students what NOT to say). With a small, knowing smile, he concluded, “And you, apparently, learned the lesson perfectly.” Following this, the Rosh Yeshiva offered a warm embrace and a bracha for Velvel’s future endeavors.
(René Magritte “Le Faux Miroir” 1929)
While the story possesses a touch of the comical, it embeds within it a kernel of deep intellectual truth. It offers a powerful expression of a central intellectual virtue that has been a foundational pillar of Torah scholarship for generations. This principle is distilled in a popular aphorism, though mistakenly attributed to Maimonides: “תכלית הידיעה שלא נדע”—the ultimate goal of knowledge is to realize our profound unknowing.
This virtue of Sh’lo Neda is not a resigned submission to limits, but an active, willful posture toward the Transcendent. It is the sober recognition that the perimeter of our understanding is a small, humanly-constructed space, whereas the sublime expanse of the unknowable stretches boundlessly beyond. True wisdom, therefore, is not measured by the facts we accumulate, but by the human capacity to stand at the edge of our own intellect and have a sobering realization of the great depth of the unknowable. This is not a flight from reason, but a strong assertion: the unknowing is a richer and more expansive domain, embracing mystery and depth that the finite borders of the knowing cannot contain.
Yet, while in the classic Yeshiva world this virtue remains a primary intellectual cornerstone, in Chassidic thought it is elevated to a central spiritual directive specifically prescribed for Purim. In the Chassidic understanding, this day is the designated time for embracing the disposition of Sh’lo Neda in our spiritual lives.
The root of this spiritual mandate lies in the very distinctive and difficult Halakha of the day, which has its origins in the Talmud (Megilah 7b). The Gemara states: “חייב אינש לבסומי בפוריא עד דלא ידע בין ארור המן לברוך מרדכי”—a person is obligated to become intoxicated on Purim until he no longer knows how to distinguish between ‘Cursed is Haman’ and ‘Blessed is Mordechai.’ This seemingly aberrant requirement prompted extensive discussion among the later Poskim, who, concerned with the dangers of inebriation, offered various alternatives, including simply sleeping on Purim. The common thread uniting all these opinions is the implicit affirmation that some form of deliberate suspension of reason and losing one’s mind is essential to the day.
This necessity is rooted in the very nature of the Purim narrative itself. The miracle we commemorate is often described as the most “un-miraculous” of all. The events are woven entirely from palace politics, human agency, and a string of coincidences that, while providential, never breach the laws of nature. It all seems logical and entirely sensible. This seamless comprehensibility is precisely the spiritual danger. The seemingly comprehensible nature of the Purim story risks leading us into a state of spiritual complacency: the world is orderly, everything adds up, and God’s ways are entirely transparent. It is at this critical juncture that the Halakha points us toward the important value of עד דלא ידע: the state of not knowing. The moment calls for a disruption of our intellectual equilibrium and our presumption of comprehension. This intentional letting go of our grasp on the rational is what allows for an unmediated encounter with the Transcendent reality that lies just beneath the visible surface of events. We are thus mandated to step into a space of deliberate ambiguity, overcoming the spiritual tedium that sets in when we assume God’s governance of the world is fully discernible to our finite reason.
This lesson of Purim, however, extends beyond the spiritual realm and carries an increasingly crucial psychological and emotional resonance for our contemporary world.
We live in an age where we are never more than a click away from the illusion of total knowledge. AI apps promise to make us know-it-alls, providing instant, definitive answers to every query, tempting us toward a state of constant, shallow certainty. In a world saturated with the temptation of all-knowingness, our emotional and psychological health demands that we learn to pause and deliberately step into a space of robust, volitional un-knowing. It is in this posture that we find liberation from the anxiety of needing to be right or in control. This intentional surrender to the unknown is an act of intellectual honesty, a spiritually sound posture, and a crucial tool for psychological wellbeing. It is in this deliberate, Purim-mandated surrender to the unknown—this act of Ad Delo Yada—that we find true psychological and spiritual liberation, trading the shallow certainty of a machine for the vast, humbling depth of mystery where a deeper sense of life can be found.
