The chapter at the beginning of the Big Book, “The Doctor’s Opinion,” was written by Dr. William Silkworth, a 1930s neurologist who spent much of his career treating people caught in the grip of “Alcoholism.”
Silkworth treated Bill Wilson at Towns Hospital in New York in late 1934. A few months later, after Bill had a spiritual experience, he asked the doctor to write a medical preface for the book he and a few others were putting together. That book, of course, became Alcoholics Anonymous.
The Doctor’s Opinion originally opened the first edition on page one. Later printings moved it to the front matter, in Roman numerals, but its purpose never changed: to lend medical credibility to what was otherwise a radical and untested spiritual approach.
But it’s worth remembering: Silkworth was writing in 1938. The field of addiction science didn’t exist. Trauma, neuroplasticity, dopamine dysregulation—none of it had names yet. What Silkworth offered was a 1930s-era attempt to understand a baffling pattern: why some people, once they start drinking, can’t stop.
What Silkworth saw clearly
Silkworth described the condition as a “physical allergy” combined with a “mental obsession.” That framing—especially the idea that the body reacts abnormally—was groundbreaking for the time. It reframed the struggle as something physiological, not moral. In that sense, he cracked open a door.
Modern research backs some of this up. We now know:
Some people’s brains are just more sensitive to alcohol. Once they start drinking, it flips a switch—what feels like control disappears, and craving takes over. That switch gets stronger the more it’s used.
Over time, heavy alcohol use changes how the brain handles impulse control, emotional regulation, and reward. It becomes harder to hit the brakes.
And what Silkworth called a “psychic change”—that total shift in how a person sees themselves and the world—is still central to recovery today. Getting sober isn’t just about stopping drinking. It’s about becoming someone who no longer needs to.
What he missed
And yet, for all that insight, Silkworth’s chapter shows its age:
Calling it an “allergy” implies an immune response. AUD isn’t that. It’s a neurodevelopmental disorder with genetic, environmental, and psychological dimensions.
There’s no mention of trauma. No nod to early abuse, neglect, or chronic stress—even though these are now understood as some of the strongest predictors of addiction.
He doesn’t touch co-occurring conditions like depression or anxiety, and there’s no framework for genetic predisposition. That wasn’t part of medicine’s vocabulary yet.
As a result, the chapter can feel a little… clinical. Like it’s describing a set of symptoms without fully understanding the system they belong to.
Still: a turning point
Bill Schaberg, in Writing the Big Book, points out how careful Silkworth had to be. He didn’t sign his name in the first edition. He was worried—about Towns Hospital’s reputation, about his own. This movement was fringe. Unproven. Maybe even foolish.
And yet he gave it his name. Eventually.
And his words—imperfect as they are—gave people something they hadn’t had before: a way to understand their suffering that didn’t rely on shame. That matters.
I don’t subscribe to the old categories. I don’t see myself as “an alcoholic.” I see myself as someone who developed a specific condition, with specific causes, and found a way to live well in spite of it. But I still have reverence for what the Doctor wrote. He helped us make the turn.

This post is part of a larger project, A Fearless Inventory, where I walk through AA’s Big Book chapter by chapter. Along the way, I try to honor the spirit of the original while also offering critique, context, and a re-framing that speaks to our time. My hope is to open a conversation — not just about how recovery looked in 1938, but how it can be lived today.
