The empathy machine
…Let’s dwell for a moment on ‘Silver Blaze’ (1892), Arthur Conan Doyle’s story of the gallant racehorse who disappeared, and his trainer who was found dead, just days before a big race. The hapless police are stumped, and Sherlock Holmes is called in to save the day. And save the day he does — by putting himself in the position of both the dead trainer and the missing horse. Holmes speculates that the horse is ‘a very gregarious creature’. Surmising that, in the absence of its trainer, it would have been drawn to the nearest town, he finds horse tracks, and tells Watson which mental faculty led him there. ‘See the value of imagination… We imagined what might have happened, acted upon that supposition, and find ourselves justified.’
Holmes takes an imaginative leap, not only into another human mind, but into the mind of an animal. This perspective-taking, being able to see the world from the point of view of another, is one of the central elements of empathy, and Holmes raises it to the status of an art.
Usually, when we think of empathy, it evokes feelings of warmth and comfort, of being intrinsically an emotional phenomenon. But perhaps our very idea of empathy is flawed. The worth of empathy might lie as much in the ‘value of imagination’ that Holmes employs as it does in the mere feeling of vicarious emotion. Perhaps that cold rationalist Sherlock Holmes can help us reconsider our preconceptions about what empathy is and what it does.
Though the scientific literature on empathy is complex, a recent review in Nature Neuroscience by a team of researchers from Harvard and Columbia including Jamil Zaki and Kevin Ochsner has distilled the phenomenon into three central stages. The first stage is ‘experience sharing’, or feeling someone else’s emotions as if they were your own — scared when they are scared, happy when they are happy, and so on. The second stage is ‘mentalising’, or consciously considering those states and their sources, and trying to work through understanding them. The final stage is ‘prosocial concern’, or being motivated to act — wanting, for example, to reach out to someone in pain. However, you don’t need all three to experience empathy. Instead, you can view these as three points on an empathetic continuum: first, you feel; then, you feel and you understand; and finally, you feel, understand, and are compelled to act on your understanding. It seems that the defining thing here is the feeling that accompanies all those stages.
