Personal identity distinguishes each of us from the rest of the human race, and is the framework within which we are individually able to discover a sense of purpose and meaning. If we had no personal identity, there would be no "me," and whatever I was or did would have little or no meaning for there would be no "me" to take responsibility or credit for it. Though we usually take our personal identity for granted, we treasure it, and react strongly if it is threatened. However, we could not have a "personal" identity if we lacked personal uniqueness. Apart from uniqueness, our identity could only be corporate at best, for we would blend and disappear into a crowd of clones. Thankfully we all do possess unique qualities that make our identities personal.

Personal identity depends upon much more than uniqueness, however.
