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.
Educational psychology
John Locke was considered one of the most influential philosophers in post-renaissance Europe in about mid 1600s. Locke was called "Father of English Psychology". One of Locke's most important works was written in 1690, named "An Essay Concerning Human Understanding". In this essay, he introduced the term "tabula rasa" meaning "blank slate." Locke explained that learning was primarily understood through experience only, and we were all born without knowledge.
