"I know how it feels to think that pure motives and actions must somehow translate into good for the world. It's a natural way for humans to think, and the pathology of it only really becomes clear when someone takes moral behavior very seriously, which is tragic because caring about morality is a good thing. It's a hard thing to learn, but we have to learn to see moral actions mechanistically the way we see less charged issues. We have to demand to know *how* an action will affect the good outcome we want, and we have to be open-minded about weighing the various harms and goods that the various available options entail. We have to see moral problems as *problems to be solved* instead of just evils to oppose. This is why the Effective Altruism movement is so important to me."
