My mother-in-law had a stroke one week ago today.

At ninety-one, she came through emergency surgery astoundingly well. In ICU, she was happy to see her children and grandchildren, called them all by name, told everyone how shocked she was that she’d had a stroke. As I greeted her, she held out her hand to me and said, “Hey, you’ve got a birthday this weekend.”

“Yes, ma’am,” I replied, in wonder.

“I haven’t forgotten,” she said, holding tight to my hand.

In the hospital and rehab, she has remained lucid, talking about books, authors, politics, and traveling she wants to do.

So when she occasionally asks, “Hey, little boy, what are you doing over there?” when no little boy is present, or “Who’s that standing behind you?” when no one is, the family gets anxious.

The physician explained: “It’s her brain at work – partly because of the area affected by the stroke and partly due to her declining vision. When she doesn’t immediately understand what she sees or what’s happening, her brain supplies the story, to make sense of it.”

I hung on every word, thinking: The power of story is profound. It’s more than reading or writing. It’s who we are, how we are wired. 

Both Scientific American and Big Think explain: “The human mind is a story processor, not a logic processor.” Our ability to solve problems, the scientists say, is tied to our understanding of story: “Perhaps story patterns can be considered another higher layer of language.”

Fascinating, isn’t it, that story is where science and the humanities meet.

Story is the essence of being human. It’s how we make sense of the world and our place in it. Story is how we attempt to understand who we are, and how we stretch the boundaries of possibility and our humanity, by imagining more: “What if . . . .”

As an educator, the visit with my mother-in-law could not have been a more striking reminder that story is critical to student learning and growth. It’s not so much the types of texts that students read, but their interpretations, their stories, about the texts that matter – and that for students truly to be critical thinkers and problem-solvers, they must go beyond synthesizing and responding to what others have written. They must look within and generate their own stories. To not do so is to hamper human nature, to not meet an intrinsically human need – and to starve the human brain.
