The Power of Holding Uncertainty: Why Not Understanding Something Can Be a Path to Insight

“The real voyage of discovery consists not in seeking new landscapes, but in having new eyes.” —Marcel Proust

Have you ever encountered an idea that felt important, yet remained just beyond your grasp? This experience often occurs when engaging with complex concepts, and it highlights a powerful, yet often overlooked, aspect of learning, and growth.

The Provocative Question of “Thoughts Without a Thinker”

This phenomenon recently struck me while reading Thoughts Without a Thinker by Mark Epstein, a psychiatrist and author who uniquely integrates Buddhist teachings with Freudian psychoanalysis [1]. The title itself is thought-provoking. Epstein explores the idea of separating the ‘thinker’ from the ‘thoughts’—suggesting that clinging to the ego and desire is a primary source of suffering, and that loosening this attachment can lead to greater peace.

The logic is compelling: thoughts are simply thoughts, transient mental events. Though, fully internalizing this concept can be challenging. It’s common to follow the reasoning but still feel the deeper meaning remains elusive.

From Cataloging Understanding to Collecting What You Don’t Recognize

What should we do when faced with such ideas? My suggestion is to embrace the uncertainty. Instead of focusing solely on what you understand, begin to actively collect what you don’t understand.

This is a shift from a common approach—quickly glossing over difficult passages and focusing on the readily digestible information. Traditionally, we aim to summarize what we’ve learned, storing the “essence” of a work in our minds while letting the unclear parts fade away.

However, there’s significant value in acknowledging and preserving those areas of uncertainty. That feeling of something “striking” you, even without full comprehension, is a crucial signal. It suggests the idea resonates on some level, triggering a connection even if you can’t yet articulate why.

The Process of Incubation and Insight

Journaling about these unclear concepts can be helpful, but the key is not to dismiss them. Allow them to linger. Psychologists refer to this as incubation, the process by which ideas continue to develop in the background of the mind [4]. Neuroscience supports this, demonstrating that the brain often continues to work on problems outside of conscious awareness, sometimes leading to sudden “Aha!” moments when seemingly disparate ideas connect. Research indicates activity in the right temporal brain and bursts of high-frequency gamma waves often precede these insights [4].

The Power of Interdisciplinary Connections

Often, the most influential discoveries arise not from deepening within a single field, but from the collision of ideas from different disciplines. This can occur as different fields frame problems in unique ways, or because tools from one field can unlock new questions in another.

A similar process can occur within our own minds. By resisting the urge to discard what we don’t understand, we allow ideas to remain in conversation with one another. Over time, these unexpected connections can spark new insights.

Embracing the “Not Yet”

Sometimes, the most important ideas are the ones we aren’t ready to understand—yet. Holding space for uncertainty isn’t a sign of intellectual deficiency; it’s a recognition that learning is a continuous process, and that true understanding often requires time, experience, and a willingness to embrace the unknown.

Mark Epstein’s work, integrating Buddhist principles with psychotherapy, exemplifies this approach. His books, including Thoughts Without a Thinker, Going to Pieces Without Falling Apart, Advice Not Given, and The Zen of Therapy, explore the interface of these disciplines [1], [2]. His work encourages a mindful approach to psychological challenges, recognizing that growth often comes from confronting—and sitting with—what we don’t yet know.
