Effective altruism is a philosophy and social movement focusing on getting the most good out of charitable activities (donations of money, time, and effort).  It has received much popular attention, but a number of philosophical issues surrounding it remain under-explored.  For example:

  • What is the best statement of effective altruism as a philosophical view, and what is its relation to consequentialism, deontology, or virtue ethics? Is the view tenable?
  • What is the most important cause? Fighting extreme poverty, reducing existential risks, or what? To what extent, if at all, should we take into consideration the well-being of possible future persons? How should we decide where to give if there is no clearly best cause?
  • To what extent is progress in ethical theory a priority, from an effective altruist perspective? For example, how important is it to figure out what well-being consists in, or to solve problems in population ethics?
