We all know you can’t derive “ought” from “is.” But it’s equally clear that “is” — how the world actual works — is going to matter for “ought” — our moral choices in the world. And an important part of “is” is who we are as human beings. As products of a messy evolutionary history, we all have moral intuitions. What parts of the brain light up when we’re being consequentialist, or when we’re following rules? What is the relationship, if any, between those intuitions and a good moral philosophy? Joshua Greene is both a philosopher and a psychologist who studies what our intuitions are, and uses that to help illuminate what morality should be. He gives one of the best defenses of utilitarianism I’ve heard.

Bonus! Joshua is a co-founder of Giving Multiplier, an effective-altruism program that lets you donate to your personal favorite causes and also get matching donations to charities that have been judged to be especially effective. He was kind enough to set up a special URL for Mindscape listeners, where their donations will be matched at a higher rate of up to 100%. That lets you get matching donations when you donate to a personal favorite cause along with a charity that has been judged to be especially effective.
