We need to assert what philosophers and religious teachers have at all times asserted: that there is something called the good life, apart from survival, and our understanding of it has to be taught, just as Mill’s father taught him the elements of Aristotle’s Posterior Analytics. Our nature may predispose us to learn; but what we learn depends on how we are nurtured.
我们需要从科学角度拯救道德。我们需要维护哲学家和宗教导师时刻教导的——有一种东西叫美好生活（good life），它独立于生存之外，对它的理解需要有人教导，正如穆勒的父亲教他亚里士多德《后分析篇》的内容。我们的天性或许能驱使我们学习，但学习什么取决于后天接受。
