Hi! This is my first post here. I had been thinking about aesthetics for philosophical movements and ended up using Effective Altruism as a case study, so it felt appropriate to share the essay, first published here, on the EA forum. Note that it's not written primarily for an EA audience, and it is somewhat of an outsider's perspective. I've been familiar with EA for several years, but I probably got some things wrong anyway. The most successful ideology of all time is arguably Christianity.
