Sam Vaknin argues that core identity (the self) is distinct from behaviors: identity is an immutable, continuous narrative formed early in life, while behaviors, choices, and roles can change across time. He discusses clinical, legal, and philosophical implications, including dissociative identity disorder, concluding that even when behavior changes dramatically the underlying self remains the same and bears responsibility. Memory and introspection are mechanisms for accessing the self, but their absence (e.g., in DID or amnesia) complicates judgments about identity and responsibility.
