Recent advances in cognitive science have allowed scientists to identify many of the brain structures and chemical substances that regulate our moral beliefs and behaviors — which has some scientists thinking we’re close to developing drugs that can control our morality.

Whether or not this is close to happening, Guy Kahane at the University of Oxford thinks the mere possibility raises a couple interesting questions:

We don’t yet know, of course, what’s possible. But it’s better to begin the ethical discussion too early than too late. And even if “moral” pills are just science fiction, they raise deep questions. Will we want to take them if they ever become available? And what does it say about us if we won’t?
