The personal identity is a representation of the person it is attached to. It extends beyond the purpose of a name, and encompasses the personality, and social identity of the person. However, the physical appearance is not what the personal identity is derived from. In locke, the personal identity stems from the consciousness itself instead of the physical body. The person identity is an important element in defining a person. If the personal identity were not derived from consciousness and instead from the body, then just about anyone who had control of the body could be known as that person. The consciousness would not matter, and the personal identity would be nothing more than a label.
