    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.

Aspiration: The Agency of Becoming

With every day, and every decision, we change, experiencing life in a way that we couldn’t imagine or envision earlier. Heraclitus, the storied pre-Socratic Greek philosopher, is famous for noting that one cannot step in the same river twice, which is a statement both about time and change. Both the river and the foot (or person wielding the foot) change with every moment, so that the circumstances will never be identical; a person can never step in the same river twice. How then can we aspire for better, for change, if we don’t know who we will become through the process of that change? How can we work towards a new way of seeing the world, if we are still guided by our old lenses? This book is an exploration of the questions about change you didn’t know you struggled…

BaDerech: Along the Path of Teshuva

How can we walk along the road of change with authenticity? In his new book, Rav Judah Mischel guides us on the complex and often difficult path of personal growth, through the thick undergrowth of doubts and anxieties that can sometimes accompany hope for a better life. In this book, stories and teachings converge, in a personal and powerful guide to growth. This book is the perfect accompaniment for the month of Elul and can inspire thoughtful introspection in all contexts. To see some of the dynamics of this book in practice, pair this book with the Autobiography of Malcolm X.. While this pairing may seem strange to those who don’t know much about Malcolm, if you make it to the end of this fascinating work, you may learn how these two books share a deeper kinship than you, or…

Transformative Experience

How can we make a decision about the future, when the person we will be when we experience the realities of that decision is a different person than we are today? In her book, L.A. Paul, a professor of philosophy in Yale famous for her ideas about “transformative experience,” explores the deepest questions of decision making. In this deeply human book of philosophical inquiry, Paul argues that we consider our life’s decisions as decisions to discover the experience of life, as our own experiences unfold from the decisions we make. If that doesn’t make sense to you yet, read the book; Paul is a far better articulator of her thought than we are.
