topic. Based on “We Can Remember It for You Wholesale” by Philip K. Dick, it raises the fundamental question – do memories define character? If your memories tell you that you are a gun-slinging, ass-kicking spy; does that make you a gun-slinging, ass-kicking spy? Bladerunner (based on Philip K Dick’s, ‘Do Androids Dream of Electric Sheep?) takes a more meditative approach to the topic. Is the film-noiresque hero, Deckard, real or not? Is he a human or is he a replicant who has forgotten that he is artificial. The random selection of antique photos on Deckard’s piano gives us a clue. Are they a record of Deckard’s past or are they a badly constructed history; a collation of tenuously linked memories. Then there’s the unicorn dream he keeps having. Again, is this his subconscious at work or another memory, implanted by Tyrell Corporation? Similarly, if you can hide memories, can you hide a personality? Take Talia Winters from Babylon 5. One minute she is a mild mannered telepath, minding her own business as best she can, the next minute her ’sleeper’ personality has been activated and she’s a cold-blooded killer. Ditto with The Long Kiss Goodnight. Amiable housewife becomes professional killer. There are many many many other examples. But just one question really. If you woke up tomorrow with a completely different set of memories, would you still be you?
