The Why and How of Effective Altruism (TED Talk)
The Life You Can Save, published in 2009, was written by Peter Singer, a proponent of the philosophy and social movement referred to as Effective Altruism. Singer's name appeared on a chalkboard in Season 1, Episode 2 of The Good Place. As a result, Schur was asked to write an introduction to the 10th anniversary edition published in 2019.
