 How, then, are we to ascribe forward looking collective responsibility in practice? At the very least, we need to make room for various kinds of practical judgments, including those that draw attention to who is best able to remedy the harm in question and at what cost. But such practical judgments, which are very important, are not the only non-causal matters that we need to take into consideration when ascribing forward looking responsibility. Indeed, as recent debates concerning our responsibility for remedying health care problems at home, starvation abroad, and environmental disasters everywhere attest, judgments about the relative value of our projects in the world are also crucial. So, too, are judgments about fairness and obligation.
