Do All Systems Have an Inner World?

No. Generally, the answer to any question that starts with “Do all systems” will be “no.” There is no “one size fits all.” Systems are created in a child’s mind, and they’re not following any rulebook. Some systems have inner worlds; some don’t; some work to build inner worlds in therapy, and some have inner worlds that only some alters can access. There is no hard and fast rule that all systems experience inner worlds.
