input: Alba expressed an interest in acting from the age of five. In 1992, the 11-year-old Alba persuaded her mother to take her to an acting competition in Beverly Hills, where the grand prize was free acting classes. Alba won the grand prize, and took her first acting lessons. An agent signed Alba nine months later. Her first appearance on film was a small role in the 1994 feature Camp Nowhere as Gail. She was originally hired for two weeks but her role turned into a two-month job when one of the prominent actresses dropped out.  Alba appeared in two national television commercials for Nintendo and J. C. Penney as a child. She was later featured in several independent films. She branched out into television in 1994 with a recurring role as the vain Jessica in three episodes of the Nickelodeon comedy series The Secret World of Alex Mack. She then performed the role of Maya in the first two seasons of the television series Flipper. Under the tutelage of her lifeguard mother, Alba learned to swim before she could walk, and she was a PADI-certified scuba diver, skills which were put to use on the show, which was filmed in Australia.  In 1998, she appeared as Melissa Hauer in a first-season episode of the Steven Bochco crime-drama Brooklyn South, as Leanne in two episodes of Beverly Hills, 90210, and as Layla in an episode of Love Boat: The Next Wave. In 1999, she appeared in the Randy Quaid comedy feature P.U.N.K.S.. After Alba graduated from high school, she studied acting with William H. Macy and his wife, Felicity Huffman, at the Atlantic Theater Company, which was developed by Macy and Pulitzer Prize-winning playwright and film director, David Mamet. Alba rose to greater prominence in Hollywood in 1999 after appearing as a member of a snobby high school clique in the Drew Barrymore romantic comedy Never Been Kissed, and as the female lead in the 1999 comedy-horror film Idle Hands, opposite Devon Sawa.

input: Lewis went on to publish Counterfactuals (1973), which contained an analysis of Counterfactual conditionals in terms of the theory of possible worlds. He had already proposed it in some of his earlier papers: "Counterpart Theory and Quantified Modal Logic" (1968), "Anselm and Actuality" (1970), and "Counterparts of Persons and their Bodies" (1971). In spite of significant technical advantages promised by this approach, the theory was widely considered to be too implausible to be taken literally, as Lewis urged it should be. Most often the idea that there exists an infinite number of causally isolated universes, each as real as our own but different from it in some way, and that furthermore that alluding to objects in this universe as necessary in order to explain what makes certain counterfactual statements true but not others, meets with what Lewis calls the "incredulous stare" (Lewis, OPW, 2005, pg. 135-137). Lewis defends and elaborates his theory of extreme modal realism, while insisting that there is nothing extreme about it, in On the Plurality of Worlds (1986). Lewis acknowledges that his theory is contrary to common sense, but believes that its advantages far outweigh this disadvantage, and that therefore we should not be hesitant to pay this price.  According to Lewis, what makes a counterfactual conditional of the form  "Had I made that shot our team would have won the game."  true is that there is a world, as concrete as ours and significantly similar to it, in which my counterpart makes rather than misses the shot and the counterpart of our team wins the game. Had there been a world even more similar to ours in which my counterpart makes the shot but the counterpart of our team still loses the counterfactual would have been false. When we speak of counterfactual possibilities we speak of what is the case in some possible world or worlds. According to Lewis, "actual" is merely an indexical label we give to a world when we locate ourselves in it. Things are necessarily true when they are true in all possible worlds. (Note that Lewis is not the first one to speak of possible worlds in this context. Leibniz and C.I. Lewis, for example, both speak of possible worlds as a way of thinking about possibility and necessity, and some of David Kaplan's early work is on the counterpart theory. Lewis's original suggestion was that all possible worlds are equally concrete, and the world in which we find ourselves is no more real than any other possible world.)
