John Locke (Lost)
John Locke was born to teenager Emily Locke on May 30, 1956. In his early years he showed extreme promise in his intelligence. After being placed in government care as a ward of the state he found himself in a variety of foster homes. He was visited in one such home by Richard Alpert (Nestor Carbonell), who described Locke as "extremely special". Locke had a number of foster siblings over the years: Jeannie, who died as a child when she fell off of a set of monkey bars; Melissa, who was prone to bullying John; and an unnamed brother with whom Locke played the game Mouse Trap.
British philosophy
Locke is also responsible for an early theory of personal identity. He thought that our being the same person from one time to another consists, not in our having the same soul or the same body, but rather the same series of psychological connections. For Locke, to be a person is to be an intelligent thinking being that can know itself as itself, the same thinking thing in different times and places.
