"Is the pious loved by the gods because it is pious, or is it pious because it is loved by the gods?" -- Socrates asks Euthyphro in Plato's "Euthyphro"
In "The Bonobo and the Atheist", Frans de Waal argues that the source of our morality is not religion. Morality is much older. It arose with life. It has been built into it. So much so that it is seen in apes, monkeys, canids (dogs), whales, and dolphins. Morality isn't an exclusively human trait.
I found de Waal's explanation compelling and uplifting. At this time when there is such confused, often heated, disagreements over what religion is and what role it should play, it is reassuring to know that nature has built in several backstops to prevent us from complete devolution into anarchy. de Waal's style in making his points is warm, not confrontational. That made them more compelling than the abrasive condescending approach of neo-atheists like Dawkins or Hitchens.
To be clear, I am not a believer, but I do want to understand the role religion has played in our history. Why does it have such a strong grip on so many of us regardless of culture? I don't want to displace religion without having something else to take its place and serve the needs it has done up to now. The good news is many civic institutions are rising up to the task. I expect that trend to continue into the future freeing us from the need to believe in something supernatural.
I enjoyed the book. I agree with de Waal's message. But, I didn't think it was as fun to read as Robert Wright's "The Moral Animal". Still, I would recommend it for you to check out. I would love to hear what you think :)
