Tomasello's novel and insightful theory of obligation explains why we sometimes sense an obligation to treat each other equally, but he has not yet explained why human morality also allows and enables much inequality in wealth and power. Ullman-Margalit's (1977) account of norms of partiality suggested a different source and kind of norms that might help to fill out Tomasello's picture.
托马塞洛新颖而有见地的义务理论解释了为什么我们有时会感到有义务平等对待彼此，但他尚未解释为什么人类道德也允许并促成了财富和权力的巨大不平等。尤尔曼-马格利特（Ullman-Margalit）的（1977）偏倚规范的解释提供了一个不同的来源和规范类型，这可能有助于充实托马塞洛的观点。
