I finished this book about a week ago and would have liked to have a more thorough review. Time doesn’t permit, so instead, I want to share a few brief thoughts. I suspect several of the themes of this book will work their way into my regular thinking on a few topics.
1) Haidt is a brilliant psychologist. He does a great job of explaining the way people think. I found myself fully convinced by his first two points which were that (a) our moral intuitions drive our moral reasoning most of the time and (b) that our moral intuitions are based on six moral “taste buds”.
2) Related: Everyone should familiarize themselves with Moral Foundation Theory and how/why it divides conservatives, progressives, and libertarians. This by itself is worth the price of the book.
3) My deepest critique of the book is not of Haidt as a moral psychologist, but Haidt as a philosopher. He offers an account of the origin of morality and religion that is purely evolutionary. For Haidt, both arose out of natural group selection because they helped groups outperform other groups. He is, therefore, relatively friendly towards religion. It’s helpful, for Haidt, it (along with morality) is an illusion.
4) This leaves Haidt’s “oughts” hollow. He ultimately argues for a sort of utilitarianism that is less individualistic, but does not (cannot) explain how he got to that conclusion. He makes many moral judgments throughout the book, but doesn’t have any of the tools to back them up. He just assumes that they will be self-evident to the reader.
5) The end result is that a lot of the descriptive parts of the book are very helpful for understanding individuals, politics, and culture. And a lot of his main points coincide very well with a biblical point of view. For instance, the Bible also teaches that we have “innate” moral intuitions. The Bible also bases its moral laws on various moral foundations (harm/care, fairness, proportionality, liberty, sanctity, etc.). The Bible also teaches that those intuitions can be trained through culture, law, parents, etc. The Bible also teaches that we operate as both individuals and as groups, etc. And these principles can be helpful in how we relate with people in different groups, even how believers share the gospel, etc. And yet, chunks of the book will nevertheless be frustrating.
6) One final thought: Haidt’s description of moral intuition as taste buds is apt. The problem is that for Haidt these don’t correspond to objective reality. I think they do. I think that these taste buds are more than just helpful tools to allow us to work together as groups to accomplish amazing things. I think they correspond to an objective moral reality. Good really is good. Evil really is evil. And the fact that we have the sense to see that, is evidence of that reality, and evidence of an ultimate law giver to his given us moral minds to see it.
