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
John Locke (1632–1704) was an empiricist at the beginning of the Modern period of philosophy. As such (and in contrast to René Descartes), he held that all of the objects of the understanding are ideas, where ideas exist in the mind. One of his goals in his work "An Essay Concerning Human Understanding" is to trace the origin of ideas. There are no innate ideas “stamped upon the mind” from birth, and all knowledge is rooted in experience. Further, there are also "simple ideas" and "complex ideas". Simple ideas enter by the senses, and they are simple and unmixed. Complex ideas are simple ideas that have been combined and related together using the abstracting activity of the mind.
