Image you are a character on Star Trek. On the starship you step into the transporter. The machine breaks down your body, and then causes the matter on Planet Xelia to become organized into a body just like yours. That person then remembers what you did before getting in the transporter and sets about pursuing your mission of gathering samples and exploring the new planet. Would Locke say that person on Xelia is same person as you? You can check out Locke's view regarding personal identity here http://www.ilt.columbia.edu/publications/Projects/digitexts/locke/understanding/chapter0227.html [Broken] What's your personal opinion(regardless of Locke)?
