Mirror Neurons and Morality

Knowledge is power. We all know it; it is in our core. If we know more, we can manipulate more. If we want to ride a horse, there are some basic facts we need to know: How to sit on a horse, how to direct a horse, how to remain on the horse when the horse makes a sudden movement. And this knowledge is not simply head knowledge. We could read five books on horse riding, but we will not really “know” how to ride a horse until we actually do it.

However, there is something we can do that accomplishes more than reading manuals about horse riding, still short of getting on the horse, and that is watching someone ride a horse. We can watch a person who is a little more skilled than we are ride a horse and learn most of what we need to actually get on the horse and try it ourselves. This doesn’t work as well if we watch a jockey racing—someone who is too advanced over us feeds us too much information and the wrong kind of information for us to try it ourselves. Besides, if we have never ridden a horse, we would rather know how to ride a horse walking than a horse at full speed.

The question is, how can we do this? There is so much information about riding a horse that it cannot be successfully communicated with words. But all we have to do is see it and suddenly we have enough information to try it ourselves. All of this is because of mirror neurons.

The mirror neuron is a recent discovery of neurology. They are parts of the brain in which we internally imitate what we see. In mirror neurons we “experience” things just by seeing them. We can watch someone playing a simple tune on a piano and even if we’ve never played before, we can sit down and try it out ourselves, with reasonable success. A savant can focus so well on this that they can accomplish great feats of skill without ever doing it before. But the basic ability to repeat what we have experienced second hand is something we all have.

And not just us. Most mammals have some level of mirror neurons. We can see this by who catches a yawn. If we see a yawn, our mind experiences it as our yawn and so replicates the act. Not only can we “catch” a yawn from a dog or a cat, but our dog or cat can “catch” a yawn from us. This means that they have some kind of mirror neuron.

However, the most successful mirror neurons are those developed by humans. There was an experiment done by an animal researcher where he allowed a chimp to hang out 24 hours a day with his son. His idea is that his son would teach the chimp how to be a human. This worked well at first, where they were creating their own games and the chimp did pick up on some pretty human traits. In the end, however, the researcher’s son became much more like the chimp than the chimp became like a human. This is because human mirror neurons are stronger, more able to pick up on others’ experiences than any other mammal. This also explains why humans have been a more successful species than other animals. Humans can draw on the experience of other humans, other animals and even insects and inanimate objects, while animals are more limited in their ability to fully know others’ activity.

Why do we have mirror neurons, let alone successful ones? Because mirror neurons have proven to be more effective in creating a successful species than any other physical apparatus. Chimps have opposable thumbs. Gorillas have the ability to learn language. And most species are more successful at obtaining food that is nutritious for them than modern humans. But humans are able to obtain and replicate more knowledge than any other species, and thus are more successful. And, because of mirror neurons, humans are able to create an ever growing store of knowledge. As a species, it only takes one person to learn something from an apple or a preying mantis or a horse, and we can all learn it. This knowledge passes on and the most successful of knowledge ends up in the permanent store of the collective human psyche.

Someone at this point will say that I am making an evolutionary argument. Not at all. God desired for humans to be more successful than other species, despite human weakness. And God created humans to be in His image. Mirror neurons are simply the apparatus by which God make human beings successful

  1. You've got to be joking?! What is the point in injecting a god into the formula - there's no deity required . . .
