My son Zack just shared this article with me. It's fascinating and thought-provoking, and highly recommended.
It's called, Six Habits of Highly Empathetic People, by Roman Krznaric. He is a founding faculty member of The School of Life in London and empathy advisor to organizations including Oxfam and the United Nations.
Mr. Krznaric contends that science is pointing us from many directions into an understanding of how human beings are actual hardwired to be empathetic, which makes a lot of sense, given that we are a highly socially-based species. He offers 6 ways that people can increase their empathy. Some are easier than others. Certainly, it's easier to talk to the person sitting next to us on the bus than it is to go live among people in a slum. But all of the ideas are well-worth exploring, however we can.
Do check out this article, with its accompanying videos.
