Maybe an asteroid hit Earth. Perhaps a nuclear war reduced our cities to radioactive rubble. Or an avian flu killed almost everyone on Earth. However it happened, the world as we know it is over and we must start again. So how do we set about rebuilding our world from scratch?
Our memories are our lives, and a fundamental basis of our culture. Collective memoirs of the past both bind society together and shape our potential future. With our brains we can travel through time and space, calling to mind places of significance, evoking images and emotions of past experiences. It’s no wonder, then, that we so desperately fear the prospect of memory loss.
What would it be like to live through the end of all that? It depends on whose theory you believe.
