Internal Family Systems: Parts, Self, and Healing Explained

Picture a therapist asking a furious client to do something strange: stop arguing the anger away and find where it lives in the body. Chest, maybe. Then ask it a question and wait for the answer. That small instruction sits at the center of Internal Family Systems, the psychotherapy model developed by Richard Schwartz, Ph.D., after clients began describing inner voices, feelings and figures that his training had taught him to be wary of. In a 2018 interview posted by the IFS Institute, Schwartz talks with interviewer Simon about what parts are, how a voice in your head differs from a part, why he capitalized the word Self, why the model borrows its name from family therapy, and what healing means when the inner world is treated as a family rather than a problem to be fixed. The spine of his account is a counterintuitive discovery: the people he worked with seemed to carry an undamaged core that knew how to heal, and he could not find where it came from.

What are "parts" in Internal Family Systems?

The model starts with a claim about the mind's makeup. Asked what parts are, Schwartz answers plainly: "Parts turn out to be little personalities inside, full range personalities." (Richard Schwartz, IFS Institute interview, 0:11)

He illustrates with anger. If you say you're angry, he explains, the working method is to have you focus on it, notice where you feel it in your body, and ask how you feel toward it. Once you're curious about it and ask it questions, something shifts. If you wait for the answer rather than deciding in advance what the anger means, you may discover it is "much more than a bundle of anger." It may carry fear. It may hold desires for you. It may be trying to protect other parts of you. Schwartz's point is that the emotion is not a single fixed thing but a character with a history and a motive.

He says he stumbled onto this as a young man, around age 32 by his account, when clients started talking about parts. His first reaction was fear, because multiplicity has been pathologized in Western culture. His second was curiosity. What he found, he says, is that these parts "have a strong desire to help us," and that "there aren't any bad ones, it turns out." That claim, that no part is inherently harmful, runs through the rest of the model.

Is every voice in my head a part?

This is the question most people bring to IFS, and Schwartz's answer is direct: "Every voice in your head is an expression of a part." (Richard Schwartz, IFS Institute interview, 2:04) The voice is only one way a part shows up. For some people a part arrives as a thought, for others as an emotion, and for others as a physical sensation.

Simon offered an everyday example, a voice reminding him to pick up the milk. Schwartz's method is the same as before: start with the voice, focus on it, and ask it questions. In his telling, the voice will often explain why it is there, how it has been struggling to keep up with everything you have to remember, and how tired it is or how badly it wants to rest. The reminder becomes a character with a job, not just a nagging thought.

Schwartz is candid that this will sound unbelievable from the outside. "I don't expect people to believe this because I'm saying it's true," he says, adding that he wouldn't have believed it either if he were watching someone describe it. His answer is experiential. He wants people to try the inquiry themselves rather than accept his word. He also notes a practical advantage: because he was trained as a family therapist and had deliberately stayed away from theories of the psyche as a set of interacting selves, he came to clients without a framework to impose. He had to listen to what they said about themselves. In his experience, most people get past the initial "Oh my God, am I multiple?" and begin to say, "Yeah, that sounds right to me."

What is the Self, and why is it capitalized?

The Self is the centerpiece of IFS, and Schwartz is clear that he arrived at it by accident. Many models talk about subpersonalities. What set his apart began in the room. When he tried to hold a dialogue between a client and one part, other parts kept interfering. Family therapists know this problem: when a third person keeps cutting into a two-person conversation, you ask that person to step out. Schwartz applied the same move to the inner family and asked the interfering parts to give the conversation some space.

When he did, something unexpected happened. In his words, a new person "would pop out of nowhere." This person was calm, confident, and curious about the part the client had been talking to. The part, which had been defensive, would soften and become willing to speak about itself and be vulnerable. When he asked who that was, clients gave the same answer: "that's not a part like these others, that's me, that's my Self."

That is why Schwartz capitalizes the word. It distinguishes the Self from the everyday meaning of "self," which refers to the whole person including all the parts. The Self is the part of the system that is not a part. He describes it with what he calls the 8 C words. The ones he names in this interview are curiosity, creativity, clarity, and connectedness. He also describes calm, confidence, compassion, and courage as qualities that show up in the Self. In his observation, the Self often feels compassion for the part it is working with almost immediately. Clarity lets the part change its image of itself so the therapist and client can see it for what it actually is. Connectedness reflects a sense that the Self wants to connect with Self in other parts and in other people, and feels much less isolated when it does.

Why did Schwartz conclude the Self is inborn?

This is the part of the story that surprised Schwartz most, and it is the one that changed his thinking. He had been trained in attachment theory, which suggested that qualities like this kind of steadiness and ego strength come from another person, from a secure relationship. So when he met clients who showed a stable Self, he combed their histories looking for the good parent or caregiver who must have given it to them.

Often, he found no such person. "There was no person in their life they could have possibly gotten that from," he recalls in the interview. Over time he had to shift his view to something more radical: that this Self is inherent in us, "sort of our birthright." Alongside the qualities, he saw a kind of wisdom about how to heal internally and externally. That led to a line he says he may one day print on a bumper sticker: "Self heals," because, in his experience, it is really true. When clients access that state and begin relating to their parts, they often take over the session, and he says he simply gets out of the way, because they really do know how to heal themselves.

He is also honest about the resistance. Both ideas, that we are multiple and that the inner core is undamaged and knows how to heal, sit uneasily with the dominant culture. Schwartz describes it as a tough sell and an uphill battle. That tension is part of why the model asks people to test it rather than believe it.

What does healing look like in IFS?

Schwartz describes parts as arriving in the world in one of two states, either dormant or manifest, with natural value in both. Trauma and attachment injuries force them out of those states. Parts then take on extreme beliefs and emotions from those experiences and carry them as if they were true. His examples include "I'm worthless," "the world is really dangerous," "I need to lash out at somebody," and "I need to withdraw all the time."

Healing, in one sense, is the release of these burdens. Schwartz compares the lifting of a burden to a curse being lifted: the part immediately transforms back into its naturally valuable state. That is the first level. The second is what he calls restoring the parts' trust in the leadership of the Self. When something bad has happened, parts often feel they must protect the system, stand in front of the bullet, and take it themselves. In doing so they lose trust in the Self and become, in his phrase, parentified children, carrying roles far too heavy for them.

This is where the name comes from. Schwartz calls the model Internal Family Systems because it mirrors what family therapists see when trauma hits a family. Kids get pushed into rigid roles, and the schools of family therapy have different names for those roles. A good family therapist can make things safe enough for those children to step out of their roles and become who they actually are. Schwartz sees the same dynamic inside. Parts are stuck in roles by their burdens, by the belief that they must protect the system, by the system's increased vulnerability, and by the fact that many are frozen in the scene where they were burdened. As he puts it, they are "frozen in time in these different trauma scenes."

Why can't willpower change these parts?

A common assumption is that a person can simply decide to stop being angry or withdrawn. Schwartz's experience is that this approach fails for parts carrying burdens. Trying to change them by willpower creates polarization inside. A part that rages or withdraws all the time, he notes, often feels fragile because it could explode at any moment, or it fails to change and feels stuck and ashamed. The effort to force a part into a different behavior sets up an internal conflict rather than resolving one.

What works, in his account, is a different kind of attention. Parts need to be understood on their own terms, and the Self has to be the one doing the understanding.

What happens during unburdening?

Schwartz describes the unburdening process through concrete moments in sessions. Parts would say they carried a fireball in their gut, and the natural impulse was to ask them to simply take it off. Some would feel better when asked. But the central insight is that the burden is tied to a specific history, and the release depends on the Self knowing what happened.

He is specific about who does this work. It is not the therapist. "The Self needs to really get what happened" when the part took on the burden. That understanding includes not only the story but the emotions and physical sensations the part felt. The Self goes into the memory, the frozen scene, and takes the part to a safe place. Schwartz says the process continues until the part signals that it has been understood: "Now I feel like you can finally get it." At that point, he says, the burden can be released. Parts that had been carrying something for thirty or forty years can feel the curse lifted and transform.

He acknowledges how this sounds. "It sounds kind of new 'woo woo,' kind of new agey at first," he says. "But it actually does work."

What is the deeper shift IFS points toward?

Near the end of the excerpt, Simon asks Schwartz what he would say if he could explain the model in one thing. Schwartz points to the way people identify with their parts and burdens. Down deep, he says, many people believe they are not very valuable. The model's aim is to help them recognize that what they really are is the Self. He connects this to spiritual traditions: "what most spiritual traditions call enlightenment is simply that shift in identity." The excerpt ends before he finishes that thought, so it is worth hearing the full video before drawing conclusions about the rest of his argument.

Where to go from here

The interview is a good introduction, but it is a conversation, not a training. Schwartz himself notes that people often need an experience of the model rather than an explanation. A few practical steps follow from what he describes:

• Watch the full 2018 IFS Institute video to hear the rest of Schwartz's answer on identity and enlightenment.
• Try the basic inquiry he describes: pick one voice, emotion, or sensation, locate it in the body, get curious, ask it a question, and wait without deciding what it means in advance.
• Notice how you respond to the parts that show up. Schwartz's view is that these parts are not bad, even when they feel that way.
• If the work stirs up something heavy, especially around trauma, look for a practitioner trained in IFS. The IFS Institute, which describes its mission as bringing more Self leadership to the world, offers training and a practitioner directory on its website, ifs-institute.com.

Schwartz's core message is simple to state and hard to fully accept: the inner family already contains what it needs to heal. The work is less about fixing the parts than about learning to listen to them, and letting the Self lead.
