In the chapter entitled "Philosophy and the Meaning of Life' in Robert Nozick's Philosophical Explanations there is an admonitory passage with many applications. "It is a puzzle', says Nozick, "how so many people, including intellectuals and academics, devote enormous energy to work in which nothing of themselves or their important goals shines forth, not even in the way their work is presented. If they were struck down, their children upon growing up and examining their work would never know why they had done it, would never know who it was that did it. They work that way and sometimes live that way, too'.¹
