After all, however great it would feel to be happy all the time, emotion control in someone else's hands is a scary prospect. One of the few scientists who might possibly know what he's talking about when it comes to the mechanics of emotions is Professor Jospeph LeDoux, author of The Emotional Brain . Creating an emotion requires synaptic changes in so many areas of the brain that it would be impossible to recreate. S o perhaps we should carry on laughing at the conspiracy theorists. But it would be worth remembering the distinguished scientists who once used the word impossible to describe heavier than air flying machines, wire transmission of voice and flying to the Moon.
Science has a worrying habit of achieving the impossible.
