Our brains do a lot of work. Though designed for survival—finding food, fighting, and procreation—we also regularly ask them unanswerable questions such as, what are we, why are we here, where do we go when we die, and why do we have to die? To really answer these questions, we may need bigger, or at least better, brains.
My novel Join, takes the old saying, “let’s put our brains together and figure this out,” very literally. When the story begins, there’s a technology that allows small groups of individuals to unify their minds, after which they can live as a single person with multiple bodies. It’s one possible strategy for enhancing brain power, but there are many others. Here are five classic stories, and one modern depiction of brain augmentation that I’ve enjoyed.
