Letters
The Therapist Who Believed His Clients
By Billy Barnard, IFS informed practitioner · July 14, 2026
The practice behind these letters was discovered by accident.
Most people assume somebody designed it. First a theory, then the techniques, then the workbook. The real order ran backwards.
It began in the early 1980s with a young family therapist named Richard Schwartz and a group of clients he couldn't help.
They had bulimia. He had a plan. The plan failed in such a strange way that following the failure produced a new map of the human mind.
I want to tell you the story, because how this map was drawn matters as much as the map itself.
Most ideas about the mind come down from an expert. This one came up from the clients. Schwartz built it by writing down what ordinary people reported about their own inner lives and taking every word seriously, including the words that sounded impossible.
In this letter, the whole story: the phrase his clients kept repeating, the fight he picked with it and lost, and the calm presence he found underneath.
The clients kept correcting him
Schwartz was a family therapist, and a successful one. He'd coauthored a major textbook in the field and was a young tenured professor with a career built on one big idea. A person's symptom lives in the family pattern around them, so you treat the pattern. Change how the family works and the symptom loses its job.
He set out to prove this on bulimia. Reorganize the family, watch the bingeing stop.
Half of it worked. The families did change. In his books he describes a client he calls Sally, whose outer life rebuilt itself across treatment: she moved out, built friendships, found work, and stepped free of the old role she'd been holding between her parents, exactly the change his model said would end the bingeing. The bingeing and purging kept coming back anyway.
When a symptom survives its own cure, it's telling you something. Out of plain frustration, Schwartz did the thing his training had skipped. He asked the clients why.
They answered in a strange, consistent dialect. A part of me gets set off. A part of me criticizes everything I do. A part of me feels worthless, and then another part takes over and binges. Sally described a whole crowd in there: a critic, a defender, a hopeless one, and the one that binged.
The word parts came from the clients. He kept it because it was theirs.
At first he filed these reports under labels he already trusted. The critic sounded like an internalized parent. The binge part sounded like a raw impulse. And once you call something an impulse, the obvious move is to overpower it. So he coached his clients to stand up to the critic and fight the part that binged.
They got worse.
Whatever these parts were, being attacked made them stronger. Critics turned crueler. Binges came harder. The war he'd organized inside his clients escalated on both sides, the way wars tend to.
The story he's told most often from this period involves a client who was hurting herself. Schwartz kept pressing the part that did it to stop, and week after week the client came back more hurt, not less. As the books that retell it put it, that was the moment he understood he couldn't win this battle.
What he did next is the hinge of the whole field. He got curious. He spoke with that part directly and learned, to his surprise, that it didn't want to win either. So he asked it what it wanted and why it was there, and an answer came back that made sense.
Parts, it turns out, will explain themselves to anyone who asks in that tone, and the books point to this one exchange, a single question asked with real curiosity instead of force, as the birth of the entire method.
What was waiting underneath
Once the fighting stopped, Schwartz did the natural thing for a family therapist. He treated the inner world as a family too.
It behaved like one. Some parts protected, others rebelled or criticized, and a few carried old pain out of sight while stronger ones stood guard in front of them. His old skills transferred. Respect the protective parts. Ask permission before approaching anything tender.
Then came the bigger discovery, and again the clients handed it to him.
He learned to make a small, polite request: would this part be willing to step back and give us some space? Parts, asked nicely, often agreed. And when enough of them stepped back, something surfaced in his clients that he'd never taught them.
They grew calm. They became curious about their own parts, even warm toward the ones wrecking their lives. Session after session, client after client, the same steady presence rose up on its own.
He asked clients what this presence was, expecting the name of yet another part. The answer, over and over, was some version of the same sentence: it's just me, it's who I really am.
Schwartz named it Self, with a capital S. In his account, Self exists in everyone, undamaged by anything that's happened, sitting, as he puts it, "just beneath the surface" of the parts. When enough parts make room, it steps forward with its calm and its courage intact.
Put together, the map reads like this. Minds come in parts from the start; we're born multiple, the way we're born with ten fingers. Hard years push parts into extreme jobs, a critic that turns brutal, a binge that buries a feeling before it can land.
And under all of them waits a Self that doesn't need repair. Healing, on this map, means helping parts set down the extreme jobs and return to what they're naturally good at, with Self back in the lead.
He called the model Internal Family Systems, IFS for short. The practice these letters draw from is informed by it.
Now look at how each piece of that map was found.
Clients said a part of me, and Schwartz let their phrase overrule his theory. Clients got worse when coached to fight themselves, and he treated the worsening as data. A part doing real harm said it wanted out of the war, and he took even that seriously. Then clients told him the calm underneath was who they really are, and their answer became the center of the model.
Every load-bearing idea in the method arrived the same way. A person described their own mind, and a therapist believed them.
That's the detail worth taking personally, because you already talk like his clients did. You've said it this week. A part of me wants to leave, and a part of me wants to stay. A part of me knew all along. The people who taught Schwartz the method spoke exactly this way, and the entire practice grew from taking that kind of sentence at face value.
I grew up in a war zone, and the parts that carried me through it spent decades being treated as defects. A method that began with a therapist believing his clients was the first one that ever believed me.
Here's the question I'll leave you with. The next time you hear yourself say a part of me, what happens if you take yourself at your word?

P.S. The practice that grew from these discoveries is what Hearth walks you through, in plain conversations informed by IFS. I built it for exactly this kind of listening. First week's free.
