As human beings we have the capacity to feel empathy. Our nervous systems are built for it. Our bodies physically react when we see another person in pain. The more connected we are to someone, the more we can respond empathetically to what they are experiencing, but we also have this capacity with strangers. This is a pro-social ability that we evolved as highly social group mammals. It is in our best interest to behave in ways that benefit the group and that foster social bonds. It is in our best interest to be able to respond effectively to the needs of our highly dependent young. We know how to read each other’s minute facial expressions and body language. We know ho to put ourselves in each other’s shoes and imagine each other’s perspectives. This is a big part of what it means to be human. We also have the ability to shut empathy off. And that is a big part of being human too.
