Is Morality All About Cooperation?

Morality as Cooperation (MAC): The Basic Theory

MAC takes as its starting point the view that human morality is about cooperation. In itself, this is not a particularly ground-breaking insight. Most moral philosophers have thought that morality has something to do with how we interact with other people — with “what we owe each other” in one popular formulation. Scott Curry, in his original paper on the MAC, does a good job reviewing some of the major works in moral philosophy and moral psychology, showing how each of them tends to link morality to cooperation.

Some people might query this and say that certain aspects of human morality don’t seem to be immediately or obviously about cooperation, but one of the claims of MAC is that these seemingly distinctive areas of morality can ultimately be linked back to cooperation. For what it is worth, I am willing to buy the idea that morality is about cooperation as a starting hypothesis. I have some concerns, which I will air below, but even if these concerns are correct I think it is fair to say that morality is, in large part, about cooperation.


In summary, the idea behind the MAC is that human moral systems derive from attempts to resolve cooperative problems. There are seven basic cooperative problems and hence seven basic forms of human morality. These are often blended and combined in actual human societies (more on this in a moment), nevertheless you can still see the pure forms of these moral systems in many different societies. The diagram below summarises the model and gives some examples of the ethical norms that derive from the different cooperative problems.
