I remember reading William MacAskill’s book Doing Good Better back in 2015 and wondering: is this too good to be true? MacAskill, the fresh-faced Oxford philosopher and prime mover of “effective altruism”, was on a mission to take personal emotion out of charitable giving. Doing good works was one thing, he suggested, but if you really wanted to scale charitable effect it was the duty of social justice warriors in the affluent west to earn as much money as possible, and then give it away in the most evidence-based fashion, to the poorest people on the planet.
