Choose your Afterlife


The questions that David Eagleman deals with at his day job at the Baylor College of Medicine in Houston are already pretty far-out: How do our brains construct reality? Why does our perception of time's flow change? Why do some people "see" music or associate lucky numbers with colours?

But even at work, some of Eagleman's ideas are so far-out they have to be put aside ... until he goes home and writes about them.

"In some sense, I use my literary fiction as a channel to explore ideas that I come up with during the day," he told me.

For example, consider how the data in your brain determines your identity. "For a long time, there's been this open question of what it would be like to be someone else - or to be something else," he said. "Once you're John Malkovich, you wouldn't remember what it's like not to be John Malkovich."

That spawned Eagleman's little story about cross-species reincarnation, titled "Descent of Species": Suppose you admired the strength and beauty of horses, and you got the chance to become a horse in your next life. Once you become a horse, would you have enough wits to appreciate that life, or even enough wits to choose the life after that? And if that's the case, what unwitting demigods might we humans have been in our past lives?

Other stories play off the fact that existential meaning doesn't scale well. "What would happen if we showed Shakespeare to a dog or a bacterium?" Eagleman asked. "It's pointless, because what's meaningful to you changes by spatial scale."
