 Batson and his collaborators have accomplished a great deal. They have formulated a sophisticated altruist hypothesis, the empathy-altruism hypothesis, that can be tested against competing egoist hypotheses, and they have designed experiments making a strong case that many of those egoist hypotheses are false. But to show that altruism is true, it is not enough to show that specific egoist hypotheses can’t explain specific episodes of helping behavior. Nor would it be enough to show that all plausible versions of egoism are false. It must also be shown that episodes of helping behavior that can’t be explained egoistically can’t be explained by another process, such as principalistic ultimate motivation or ultimate motivation by a non-moral norm. In addition, the defender of altruism must show that non-egoistic episodes of helping behavior are not the product of the habitual or Pavlovian systems. None of Batson’s experiments were designed to rule out these non-egoistic options or others that might be suggested. So there is still much work to be done.
